Occupational and Construction Safety

EHS promotes safe work practices and provides occupational safety services to university employees in accordance with Occupational Safety and Health Administration requirements and industry standards. The University has developed safety and health programs to help provide a safe working environment for faculty, staff, students, and visitors.

These occupational safety programs include asbestos work, confined space entry, electrical safety, indoor air quality, lead exposure in construction, personal protective equipment, and forklift use.

EHS staff are available to consult on any occupational safety issue. Training classes are provided to make sure all stakeholders have the latest information relevant to performing their jobs in a safe manner.

The following occupational safety programs are administered by EHS:

Confined Spaces

1.0 Introduction

Many workplaces contain spaces which are considered "confined" because their configuration can hinder the activities of employees who must work in them. In addition, there are many instances where employees who work in confined spaces face increased risk of exposure to serious hazards. Some confined spaces pose entrapment hazards, while others restrict air circulation so that hazardous atmospheres may accumulate. Other hazards include exposure to electrical shock, contact with chemicals, heat stress, and moving parts of machinery. OSHA uses the term "permit-required confined space" to describe those spaces which meet the definition of "confined space" and pose health or safety hazards.

2.0 Definitions

Atmosphere-controlled confined space - A permit-required confined space in which potential or actual atmospheric hazards can be controlled with continuous forced mechanical ventilation. Entrants are not required to use a retrieval system.
Attendant - an individual stationed outside the permit space who monitors the authorized entrants
Confined space - a space that is large enough for an employee to bodily enter and perform assigned work, has limited or restricted means for entry or exit, and is not designed for continuous occupation.
Entry permit - a written document provided by the employer to allow and control entry into a permit space
Entry supervisor - a person responsible for determining if acceptable entry conditions are present, for authorizing entry and overseeing entry operations, and for terminating entry
Fully regulated permit-required confined space - A permit-required space that contains a hazard that cannot be controlled or eliminated. Entry into this space requires a retrieval system.
Hazardous atmosphere - Atmospheric conditions are considered hazardous if oxygen levels are less than 19.5% or greater than 23.5%, a combustible gas is greater than 10% of its lower explosive limit (LEL), a toxic substance exceeds an OSHA or American Conference of Governmental Industrial Hygienists (ACGIH) limit, an airborne combustible dust obscures vision at five feet or less, or any atmospheric condition recognized as immediately dangerous to life or health (IDLH).
Hot work permit - the employer's written authorization to perform operations capable of providing a source of ignition (e.g., welding, cutting, and brazing)
Non-permit confined space - a confined space that does not contain or have the potential to contain any hazard capable of causing death or serious physical harm
Permit required-confined space - a confined space that contains one or more of the following characteristics:
- A known or potentially hazardous atmosphere.
- An engulfment hazard.
- Has an internal configuration that could trap a worker.
- Contains any other recognized serious safety or health hazard.
Retrieval system - equipment used for non-entry rescue of persons from permit spaces. Includes a retrieval line, chest or full-body harness and a lifting device or anchor.

3.0 Program

澳门老奇人论坛 will comply with the Standard by developing and implementing a written Permit-Required Confined Space Entry Program. The program will include provisions for employee training, hazard identification and control, permit system, and rescue procedures.
This program applies to all permit spaces except telecommunication manholes, which are covered by a separate standard.
The program is maintained in the Facilities Management Department and the Safety Office and is updated as necessary by the Safety Manager. The program is available in the Facilities Management Library for inspection by employees.

4.0 Identification of Spaces

A survey to identify permit-required confined spaces at the university will be conducted by the Safety Office and the Facilities Management Department. The inventory will be maintained in the Facilities Management Department and the Safety Office and updated by the Safety Manager.
Confined spaces will be identified by signs, lists, color coding, and/or training programs. Affected employees will be notified of the hazards and that only authorized individuals may enter these spaces.
Confined spaces will be classified as non-permit or permit-required. Permit-required spaces will be classified as atmosphere-controlled or fully regulated spaces.

5.0 Training

All personnel involved in confined space work shall receive appropriate training in hazard recognition, personal protective equipment, safety equipment, communications equipment, procedures for calling rescue services, and proper use of rescue equipment. Training shall be performed before the employee is assigned duties in confined spaces.
Training will be conducted under the coordination and supervision of the Safety Office. Retraining will be performed at least annually. Training records will be maintained by the Safety Manager.
At least one member of the rescue team will receive training in basic first-aid and cardiopulmonary resuscitation (CPR) and maintain a current certification.
Workers will be trained in the hazards associated with special work practices such as welding, cutting, and the use of chemicals.
Individuals who perform atmospheric testing will be trained by the Safety Manager. Training will cover field checks, normal use, and specific limitations of the equipment.

6.0 Testing the Atmosphere

The atmosphere in all permit-required confined spaces shall be tested for oxygen concentration, combustible gases, and known or suspected toxic substances immediately prior to entry. A properly calibrated direct reading gas monitor will be used. Calibration will be performed at least every six months by the Safety Office. Prior to use, the equipment will be field checked to ensure that it is operating properly. Gas detector tubes may also be used to test potentially toxic atmospheres.
Atmosphere testing must be performed by a person qualified by the Safety Office. From outside the structure, sampling will be performed at various levels within the confined space, and around all conduits, pipes, or cables. Sampling will be started at the top of the vessel to detect the presence of lighter than air combustibles and toxins. Sampling may be performed with a remote probe. "Listed" intrinsically safe equipment will be used if the monitor is lowered into the confined space.
The atmosphere shall be tested in the following order: oxygen concentration, combustible gases, and toxic materials. Results will be written on the entry permit. If the test instrument indicates the atmosphere is safe and there is no potential for a hazardous atmosphere, workers will be allowed into the space without respiratory protection.
The Facilities Management Director, Assistant Director, or the Safety Manager must be notified immediately if atmospheric conditions are hazardous. Entry will be prohibited until conditions are brought into acceptable limits by purging, cleaning and/or ventilating the space, or appropriate respiratory equipment is worn. Respirators must be approved by the Safety Office.
Testing will be repeated at least hourly or more often depending on the possibility of changing conditions. Monitoring must be continuous if the potential for a hazardous atmosphere exists. For example, continuous monitoring is required for entry into sewers and during welding operations. Atmosphere testing must be recorded on the entry permit.
Any employee who enters the space will be provided an opportunity to observe the pre-entry testing and any periodic testing.
Authorized entrants will be immediately provided with the results of the testing.

7.0 Physical Hazards

If the space poses serious health or safety hazards other than atmospheric either the hazards must be eliminated prior to entry or the space must be entered using retrieval equipment.
If energized parts of electrical equipment are exposed, the circuit parts must be de-energized and tagged or locked out. Mechanical sources in a confined space that could be hazardous must be tagged and locked out or guarded.
Belt and chain drives and mechanical linkages on shaft-driven equipment will be disconnected where possible.
Mechanical moving parts within a confined space will be secured with latches, chains, chocks, blocks, or other devices.
All pumps or lines which convey flammable, injurious, toxic or oxygen displacing gases into a confined space shall be disconnected, or effectively isolated to prevent the development of a hazard in the space. The closing and locking of valves alone are not considered effective protection.

8.0 Mechanical Ventilation

Continuous forced mechanical ventilation must be used in all permit-required confined spaces that contain a known or potential atmospheric hazard.
Mechanical ventilation must be used regardless of initial monitoring results if a potential for a hazardous atmosphere still exists. The potential for a hazardous atmosphere will be determined by supervision in consultation with the Safety Manager.
Ventilation systems used in flammable atmosphere shall be explosion-proof and appropriately rated for the hazard. Air will be from a clean source. Oxygen will not be used to ventilate a confined space.
If a hazardous atmosphere is detected, employees will not enter the space until the hazardous atmosphere has been eliminated by continuous forced air ventilation. If it is possible for the hazardous atmosphere to return then retrieval equipment must be worn.
The forced air will be directed to the immediate vicinity where an employee is or will be present within the space. Ventilation shall continue until all employees have left the space.

9.0 Entry Permits

A fully completed entry permit will be prepared by the entry supervisor prior to entry into a permit-required confined space. The entry supervisor will be in charge of the entry and must be approved by the Director of Facilities Management and the Safety Manager.
The entry supervisor will ensure that the permit specifies the location, type of work, type of space, personal protective measures, authorized entrants, monitoring equipment and calibration date, hazards of the permit space, atmosphere testing, and control measures. Rescue equipment and rescue services will also be included on the permit.
The permit will be dated and carry an expiration time limiting the work to one shift (12 hours). The permit may be extended for another shift if conditions are still acceptable.
The entry supervisor shall sign the permit prior to allowing entry and ensure that entry operations remain consistent with the terms on the permit. The entry must be terminated if a potential hazardous situation occurs which exceeds the conditions authorized on the permit.
The permit will be available at the work site outside the confined space for inspection by all workers.
All confined space entry permits will be turned into the department supervisor after the work is completed. The Safety Office will keep the permits and related information for a minimum of three years.
Hot work (potential ignition sources) shall be authorized on a separate hot work permit and attached and noted on the entry permit.
Entry supervisors may also serve as entrants or attendants.
After the entry has been completed the permit will be canceled by the entry supervisor. Cancellation of the permit indicates that the space is ready to be returned to its normal operating mode.
Entry permits will be reviewed yearly. The program will be revised as necessary to ensure that the health and safety of employees are not compromised.
The space will be reevaluated and a new permit issued if an entrant has reason to believe that the evaluation may not have been adequate.

10.0 Entry Procedures

All permit-required confined spaces

Only individuals authorized and trained by the Safety Office are allowed to enter a permit-required confined space.
The Safety Manager, Director of Facilities Management, and/or entry supervisors will evaluate the space for potential atmospheric and physical hazards prior to entry. Hazards will be controlled or eliminated if possible.
An entry permit will be properly completed by an entry supervisor prior to entry into the confined space.
Any condition making it unsafe to remove an entrance cover will be eliminated before the cover is removed. When a cover has been removed, the opening shall be promptly guarded to prevent an accidental fall through the opening and prevent objects from falling into the hole. Appropriate vehicle and pedestrian barriers will be used to protect workers. Cylinders of compressed gases, except those used with SCBAs, shall never be taken into a confined space.
Any entry into a permit-required confined space will require atmosphere testing for oxygen content, flammable gases and vapors, and potential toxic air contaminants by a properly trained individual. The Director of Facilities Management, Assistant Director, or the Safety Manager must be notified prior to entering a permit-required confined space that contains a hazardous atmosphere.
An attendant with a communication device will remain outside the permit space during all entries.
During confined space entry, all safety rules and procedures must be followed. Metal ladders will not be used when working around electrical equipment. Adequate lighting will be provided. There shall be no smoking in a confined space.
Continuous forced air mechanical ventilation must be used if there is a hazardous or potentially hazardous atmosphere in the space. Any use of chemicals, welding, cutting, or soldering must be approved by supervision and the Safety Manager.
Personal protective equipment (PPE), including respirators, will be provided to workers as necessary for safe entry into the confined space. All PPE must be approved by the Safety Manager.
Electrical equipment used in the confined space must be appropriate for the hazard and meet the requirements of the National Electric Code if a hazardous atmosphere is present. Electrical cords, tools, and equipment will be visually inspected for defects prior to use in a confined space. All electrical equipment must be connected to a ground fault circuit interrupter.
Entry operations will be reviewed if there is reason to believe that the measures taken under this program are not adequate to protect employees. The program will be revised as necessary to correct problems.

Atmosphere controlled permit spaces

If the only hazard posed by the permit space is an actual or potential hazardous atmosphere that can be controlled by continuous forced air ventilation alone, workers may enter the space without retrieval equipment.
Flammable and toxic atmospheres must be less than 50% of a "hazardous atmosphere" to qualify as an atmosphere-controlled space.
Continuous monitoring must be performed. Monitoring results must be documented on the entry permit every hour.

Fully regulated permit spaces

Workers entering a permit space containing an uncontrolled hazardous atmosphere or other uncontrolled serious health or safety hazard will wear full retrieval equipment.
Full retrieval equipment must be worn if it is likely that the hazardous atmosphere will return.
Monitoring must be continuous if a hazardous atmosphere is detected.
Each individual entering a confined space containing an uncontrolled hazardous atmosphere, a potential for engulfment, or other serious health or safety hazard will have a safety line attached to a chest or full body harness. The other end of the line will be secured to an anchor point or lifting device outside the entry portal. The anchor point will not be a motor vehicle. When entry is made through a top opening, a lifting device such as a tripod will be used for lifting employees out of the space.
An individual may enter a confined space containing a hazardous atmosphere without a lifeline if a positive-pressure SCBA or air-line respirator with a 10 minute escape bottle is worn.
The Safety Office and The Radford City Fire Department will be notified prior to the entry.

Non-permit confined spaces

When there are changes in the use of a non-permit confined space that may increase the hazards, the space will be re-evaluated and classified as a permit-required space if necessary.
A space classified as a permit-required confined space may be re-classified as a non-permit space if the following conditions are met:
The space poses no actual or potential atmospheric hazard
All hazards are eliminated prior to entry (control of atmospheric hazards through forced air ventilation does not constitute elimination of hazards)
If it is necessary to enter the permit space to eliminate hazards entry must be performed in according to the requirements of an atmosphere-controlled space or fully regulated space.

Excavating and Trenching

1.0 Introduction

Excavation and trenching cave-ins result in more than one hundred fatalities annually in the United States. With little or no warning, an unsupported, improperly shored or sloped trench or excavation wall can collapse, trapping workers below in seconds. For each fatality there are an estimated fifty related serious injuries annually. In addition to human losses the financial costs can be enormous--property damage, work stoppage, and workers' compensation.

The purpose of this program is to protect employees from hazards that may be encountered while working in trenches and excavations. The program includes provisions for employee training, hazard identification and control, and safe work practices that must be followed while working in an excavation or trench. This program complies with Occupational Safety and Health Administration (OSHA) standard 29 CFR 1926 Subpart P.

2.0 Scope

This program applies to all open excavation made in the earth's surface, including trenches. It covers all employees that work in or around excavations.

3.0 Definitions

Accepted engineering practices - the standards of practice required by a registered professional engineer.
Aluminum Hydraulic Shoring - a manufactured shoring system consisting of aluminum hydraulic cylinders (crossbraces) used with vertical rails (uprights) or horizontal rails (wales). This system is designed to support the sidewalls of an excavation and prevent cave-ins.
Bell-bottom pier hole - a type of shaft or footing excavation in which the bottom is made larger than the cross section above to form a belled shape.
Benching - a method of protecting employees from cave-ins by excavating the sides of an excavation to form horizontal steps, usually with vertical or near-vertical surfaces between levels.
Cave-in - the sudden movement of soil or rock into an excavation, or the loss of soil from under a trench shield or support system, in amounts large enough to trap, bury, or injure a person.
Competent person - one who has been trained to identify hazards in the surroundings or working conditions and has the authority to have these hazards promptly corrected. For purposes of this standard, a competent person must have specific training in, and be knowledgeable about, soil analysis, protective systems, and the requirements of this standard. The competent person shall determine the means of protection (sloping back the sides of the excavation, use of trench shields, or shoring) that will be used for each excavation project.
Cross braces - the horizontal members of a shoring system installed perpendicular to the sides of the excavation. The cross braces bear against either uprights or wales.
Excavation - any man-made cut, cavity, trench, or depression in an earth surface formed by earth removal.
Faces or sides - the vertical or inclined earth surfaces formed as a result of excavation work.
Failure - the movement or damage of a structural member or connection that makes it unable to support loads.
Hazardous atmosphere - an atmosphere that is explosive, flammable, corrosive, oxidizing, irritating, oxygen deficient, toxic, or otherwise harmful, that may cause death, illness, or injury.
Kickout - the accidental movement or failure of a crossbrace.
Protective System - a method of protecting employees from cave-ins from material that could fall from an excavation face or into an excavation, or from the collapse of adjacent structures. Protective systems include shoring, sloping, shield systems or other systems that provide the necessary protection.
Ramp - an incline walking or working surface used to gain access to one point from another. A ramp is constructed of earth or structural materials such as steel or wood.
Sheeting - the members of a shoring system that retain the earth in position and in turn are supported by other members of the shoring system.
Shield - a structure that withstands cave-ins and protects employees working within the shield system. Shields can be permanent structures or portable units moved along as work progresses. Shields used in trenches are usually called "trench boxes" or "trench shields." Shields do not generally prevent cave-ins but protect employees if a cave-in occurs.
Shoring - a structure that supports the sides of an excavation to prevent cave-ins. Shoring systems may be hydraulic, mechanical, or made from timber.
Sloping - inclining the sides away from the excavation to protect employees from cave-ins. The required slope will vary with soil type, weather, and surface loads that may affect the soil in the area of the trench (such as adjacent buildings, vehicles near the edge of the trench)
Stable rock - natural solid mineral material that can be excavated with vertical sides that will remain intact while exposed. Rock which contains visible fractures or seams, or rock (e.g., shale) which is interlayed with clay or soil does not constitute stable rock.
Structural ramp - a ramp built of steel or wood, usually used for vehicle access. Ramps made of soil or rock are not considered structural ramps.
Support system - a structure such as underpinning, bracing, or shoring, which provides support to an adjacent structure, underground installation, or the sides of an excavation.
Tabulated Data - tables and charts approved by a registered professional engineer used to design and construct a protective system.
Trench - a narrow excavation (in relation to its length) made below the surface of the ground. In general, the depth is greater than the width. The width of a trench measured at the bottom is less than 15 feet.
Uprights - the vertical members of a trench shoring system placed in contact with the earth and usually positioned so that individual members do not contact each other. Uprights spaced so that individual members are closely spaced, in contact with or interconnected to each other are often called "sheeting."
Wales - horizontal members of a shoring system placed parallel to the excavation face whose sides bear against the vertical members of the shoring system or earth (the uprights or sheeting)

A warning system is not required for mobile equipment used to push soil back into the trench.

Hazardous Atmospheres

A qualified individual will test the atmosphere in excavations over four feet deep if a hazardous atmosphere is possible. The qualified individual will be trained by the Safety Office. A hazardous atmosphere may exist, for example, in excavations in landfill areas, where hazardous substances are stored, or near gas pipelines.
Adequate precautions will be taken to prevent exposures to atmospheres containing less than 19.5 percent oxygen and other hazardous atmospheres. These precautions include proper respiratory protection or forced mechanical ventilation.
Forced mechanical ventilation shall be used to prevent exposure to an atmosphere containing a flammable gas in excess of 10 percent of its lower flammability limit.
When controls are used to reduce the level of atmospheric contaminants to acceptable limits, continuous air monitoring will be performed. The device used for atmospheric monitoring will be equipped with an audible and visual alarm.
Atmospheric testing will be performed using a properly calibrated direct reading gas monitor. Direct reading gas detector tubes or other acceptable means may also be used to test potentially toxic atmospheres.
Atmospheric testing instruments shall be calibrated at least every six months by the Safety Office.
Each atmospheric testing instrument will be field checked immediately before use to ensure that it is operating properly.
Emergency rescue equipment such as breathing apparatus, safety harness and line, and a tripod shall be readily available where hazardous atmospheres may develop in an excavation. Only personnel that have approved training and appropriate equipment shall attempt retrieval into a hazardous atmosphere.
If entry into a known hazardous atmosphere must be performed, the Safety Office shall be given advanced notice so hazards can be evaluated and rescue personnel placed on standby.

Personal Protective Equipment

All employees working in trenches or excavations shall wear approved hardhats and steel toed shoes.
Employees exposed to flying fragments, dust, or other similar materials shall wear approved safety glasses with side shields.
Employees exposed to hazards produced by welding, cutting or brazing operations shall use approved spectacles, faceshield, or helmet.

There shall be no indications while the trench is open of a possible loss of soil from behind or below the bottom of the support system.
Installation of a support system shall be closely coordinated with the excavation of trenches.

Appendix A: Soil Classification

Appendix A describes a method of classifying soil and rock deposits based on site and environmental conditions, and on the structure and composition of the earth deposits. The appendix contains definitions, requirements, and describes acceptable visual and manual tests for use in classifying soils.

This appendix applies when a sloping or benching system is designed as a method of protection for employees from cave-ins. This appendix also applies when timber shoring is designed according to appendix C and aluminum hydraulic shoring is designed according to appendix D. Appendix A also applies if other protective systems are designed from data requiring that soil be classified.

Each soil and rock deposit must be classified by a competent person as stable rock, type A, type B, or type C soil. Type A soil is the strongest (e.g., clay) and Type C soil is the weakest and most unstable (e.g., sand). Classification is based on at least one visual and one manual analysis. Analysis may be done using the methods described in this appendix or any other recognized method of soil classification and testing such as those adopted by the American Society for Testing Materials.

Once the soil type has been determined the proper protective system can be selected. Each layer in a layered system must be classified. The protective system for the weakest layer must be chosen. Soils may have to be reclassified in case of a heavy rainstorm or other hazard-increasing occurrence.

Appendix B: Sloping and Benching

This appendix is mandatory if the employer decides to classify the soil and chooses a sloping or benching system. The slopes in the appendix are the maximum allowable slopes for each type of soil, i.e., the steepest incline allowed for the particular soil. Slopes are expressed as a ratio of horizontal distance to vertical rise. In Type C soil, for example, a trench 10 feet deep would require a horizontal distance of 15 feet on both sides of the trench (1 1/2:1). The only exception to the maximum allowable slopes is for short-term (less than 24 hours) excavations in Type A soil where the excavation is 12 feet or less in depth. The slope for such an excavation can be 1/2:1 rather than 3/4:1.

Following are the maximum allowable slopes for excavations less than 20 feet deep:

Soil Type	Slope
Stable Rock	Vertical
Type A	3/4:1
Type B	1:1
Type C	1 1/2:1

Appendix C: Timber Shoring

This appendix is mandatory when an employer uses timber shoring in a trench 20 feet or less in depth. The employer must first classify the soil using Appendix A, then select the proper configuration from the tables in appendix C.

Appendix D: Aluminum Hydraulic Shoring for Trenches

This appendix is mandatory when an employer uses aluminum hydraulic shoring in a trench 20 feet or less in depth. This option is only used when the employer cannot utilize manufacturers' tabulated data. The employer must first classify the soil using Appendix A, then select the proper configuration from the tables in this appendix.

Personal Protective Equipment

1.0 Introduction

Employers are required to correct conditions that endanger the health and safety of workers. The most reliable method is to reduce or eliminate hazards through engineering controls. This includes enclosing the operation, using less toxic materials, and providing proper ventilation. Administrative controls may also be used, such as limiting the amount of time an employee works in a hazardous area. However, when hazards cannot be controlled by these means, the use of personal protective equipment (PPE) may be required to protect employees from workplace hazards and contaminants. PPE can also provide added protection to employees even if the hazard has been controlled by other means.

Several types of personal protective equipment are available to protect workers from hazards they may encounter on the job. These include eye protection, gloves, protective clothing, respirators, hard hats, harnesses, safety shoes, and hearing protection. PPE is only effective if the equipment is selected based on its intended use, employees are trained in its use, and the equipment is properly tested, maintained, and worn.

2.0 Procedures

General. Personal protective equipment shall be used whenever chemical, biological, or physical hazards are encountered in a manner capable of causing injury through absorption, inhalation, or physical contact. PPE does not eliminate the hazard and if the equipment fails exposure to the hazard will occur. To reduce the possibility of failure, PPE must be properly fitted and maintained in a clean and serviceable condition.
Hazard Assessment. The Safety Office, in cooperation with management and employees, will assess the workplace and determine if hazards are present that may require the use of PPE. If hazards are found, properly fitted PPE will be used by employees. The hazard assessment will be certified in writing and kept in the Safety Office.
Training. Before doing work that requires the use of PPE, the Safety Office will train personnel in the proper use and maintenance of the equipment. Training records will be maintained in the Safety Office. Training will include the following: when PPE is necessary, what type of PPE is required, how it is to be worn, what its limitations are, and the proper care, maintenance, and disposal of PPE. Retraining will be performed if the employee does not understand how to use PPE properly or if the need for PPE changes.
Approval. All PPE must be approved by the Safety Office to ensure that it meets OSHA requirements. Management may determine specific types of safety equipment based on price, comfort, and style.
Supply. Personal safety equipment, except safety shoes and prescription safety glasses, will be supplied by individual departments at no cost to employees and remain the property of 澳门老奇人论坛.
Responsibilities. Employees are responsible for wearing and properly maintaining PPE. Supervision shall ensure that all regulations regarding the use of personal safety equipment are enforced.
Hazard reduction. Providing personal safety equipment should not deter efforts by management to eliminate hazards at the source through engineering design, administrative controls or the substitution of less hazardous materials.
Maintenance. All PPE should be inspected for tears, leaks, punctures, breaks, contamination, or signs of wear before use. Damaged or defective equipment should not be used. PPE should be stored carefully to prevent damage and kept clean. Contaminated PPE that cannot be decontaminated should be disposed of properly.

OSHA - Job Safety and Health Protection

The Virginia Occupational Safety and Health (VOSH) law, By the authority of title 40.1 of the labor laws of Virginia, provides job safety and health protection for workers. The purpose of the law is to assure safe and healthful working conditions throughout the state. The Virginia safety and health codes board promulgates and adopts job safety and health standards, and employers and employees are required to comply with these standards.

Employers: Each employer shall furnish to each of his employees employment and a place of employment free from recognized hazards that are causing or are likely to cause death or serious harm to his employees; and shall comply with occupational safety and health standards issued under the Law.

Employees: Each employee shall comply with all occupational safety and health standards, rules, regulations and orders issued under the law that apply to his own actions and conduct on the job.

Inspections: The Law requires that a representative of the employer and a representative authorized by the employees be given an opportunity to accompany the VOSH inspector for the purpose of aiding the inspection. Where there is no authorized employee representative, the VOSH inspector must consult with a reasonable number of employees concerning safety and health conditions in the workplace.

Citations: If upon inspection VOSH believes an employer has violated the law, a citation alleging such violations will be issued to the employer. Each citation will specify a time period within which the alleged violation must be corrected. The VOSH citation must be prominently displayed at or near the place of alleged violation for three days or until the violation is corrected, whichever is later, to warn employees of dangers that may exist there.

Proposed Penalty: The Law provides for mandatory penalties against private sector employers of up to $1,000 for each serious violation and for optional penalties of up to $1,000 for each other-than-serious violation. Penalties of up to $1,000 per day may be proposed for failure to correct violations within the proposed time period. Also, any employer who willfully or repeatedly violates the Law may be assessed penalties of up to $10,000 for each such violation.

Public Sector employers, all departments, agencies, institutions or other political subdivisions of the Commonwealth, are exempt from the penalty provisions of this Law.

Criminal penalties are also provided for in the Law. Any willful violation resulting in the death of an employee is punishable, upon conviction, by a fine of not more than $10,000 or imprisonment for not more than six months, or by both. Conviction of an employer after a first conviction doubles these maximum penalties.

Complaint: Employees or their representatives have the right to file a complaint with the nearest VOSH office requesting an inspection if they believe unsafe or unhealthful conditions exist in their workplace. VOSH will withhold, on request, names of employees complaining. Complaints may be made at the Department of Labor and Industry regional offices or the State office as shown below.

Discrimination: The Law provides that employees may not be discharged or discriminated against in any way for filing safety and health complaints or otherwise exercising their rights under the Law. An employee who believes he has been discriminated against may file a complaint with the Commissioner of the Virginia Department of Labor and Industry and/or the Federal Occupational Safety and Health Administration (OSHA) Regional Office within 30 days of the alleged discrimination.

Caspa: Complaints Against State Plan Administration: any person may complain to the Regional Administrator of OSHA (address below) concerning the Administration of the State Safety and Health program.

State Coverage: The VOSH program shall apply to all public and private sector businesses the State except for Federal agencies, businesses under the Atomic Energy Act, railroad rolling stock and tracks, certain federal enclaves, and businesses covered by the Federal Maritime jurisdiction.

Voluntary Activity: Voluntary efforts by the employer to assure his workplace is in compliance with the Law are encouraged. Voluntary Safety and Health Compliance and Training Programs exist to assist employers. These services may be obtained by contacting the Main State Office or any Regional Office.
