eye or face injury. Eye and face protective equipment must meet the requirements of ANSI Z87.1-1968, Practice for Occupational and Educational Eye and Face
Employees involved in welding operations must be furnished with filter lenses or plates of at least the proper shade number. Employees exposed to laser beams must be furnished suitable laser safety goggles that will protect for the specific wave length of the laser and the optical density adequate for the energy involved.
Employers are required to assess the workplace to determine if the walking/working surface on which employees are to work have the strength and structural integrity to safely support workers. Employees are not permitted to work on those surfaces until it has been determined that the surfaces have the requisite strength and structural
integrity to support the workers.
Where employees are exposed to falling 6 feet or more from an unprotected side or edge, the employer must select a guard-rail system, safety net system, or personal fall arrest system to protect the worker.
A personal fall arrest system consists of an anchorage, connectors, body harness and may include a lanyard, a deceleration device, lifeline or a suitable combination of these. Each employee in a hoist area must be protected from falling 6 feet or more by guardrail systems or personal fall arrest systems. If guardrail systems (or chain gate or guardrail) or portions thereof must be removed to facilitate hoisting operations, as during the landing of materials, and a worker must lean through the access opening or out over the edge of the access opening to receive or guide equipment and materials, that employee must be protected by a personal fall arrest system.
Personal fall arrest systems, covers, or guardrail systems must be erected around holes (including skylights) that are more than 6 feet above lower levels.
Each employee at the edge of an excavation 6 feet deep or more must be protected from falling by guardrail systems, fences, barricades, or covers. Where walkways are provided to permit employees to cross over excavations, guardrails are required on the walkway if it is 6 feet or more above the excavation.
Each employee using ramps, runways, and other walkways must be protected from falling 6 feet or more by guardrail systems.
Each employee performing overhand bricklaying and related work 6 feet (1.8288 meters) or more above lower levels must be protected by guardrail systems, safety net systems, or personal fall arrest systems, or must work in a controlled access zone.
All employees reaching more than 10 inches below the level of a walking/working surface on which they are working must be protected by a guardrail system, safety net system, or personal fall arrest.
Each employee engaged in roofing activities on low-slope roofs with unprotected sides and edges 6 feet or more above lower levels must be protected from falling by guardrail, safety net, or personal fall arrest systems or a combination of a:
• warning line system and guardrail system,
• warning line system and safety net system,
• warning line system and personal fall arrest system, or
• warning line system and safety monitoring system.
On low-slope roofs 50 feet or less in width, the use of a safety monitoring system without a warning line system is permitted. Each employee on a steep roof with unprotected sides and edges 6 feet (1.8288 meters) or more above lower levels must be protected by guardrail systems with toeboards, safety net systems, or personal fall arrest systems.
A firefighting program is to be followed throughout all phases of the construction and demolition work involved. It must provide for effective firefighting equipment to be available without delay, and designed to effectively meet all fire hazards as they occur.
Firefighting equipment must be conspicuously located and readily accessible at all times, must be periodically inspected, and be maintained in operating condition.
A fire extinguisher, rated not less than 2A, must be provided for each 3,000 square feet of the protected building area, or major fraction thereof. Travel distance from any point of the protected area to the nearest fire extinguisher must not exceed 100 feet. Acceptable substitutes are a 1/2–inch diameter garden-type hose not to exceed 100 feet and capable of discharging a minimum of 5 gallons per minute, or a 55–gallon drum of water with two fire pails.
One or more fire extinguishers, rated not less than 2A, must be provided on each floor. In multistory buildings, at least one fire extinguisher must be located adjacent to stairway.
The employer must establish an alarm system at the worksite so that employees and the local fire department can be alerted for an emergency.
When signs, signals, and barricades do not provide necessary protection on or adjacent to a highway or street, flagmen or other appropriate traffic controls must be provided. Flagmen must be provided with and must wear a red or orange warning garment while flagging. Warning garments worn at night must be of reflective material.
