How close should safety nets be to the working surface?
30 feet
Safety nets must be installed as close as practicable under the surface on which employees are working, but in no case more than 30 feet below. When nets are used on bridges, the potential fall area must be unobstructed.
How often must perimeter guardrail cables be flagged?
6′ intervals
Flagging must be present at a minimum of 6′ intervals with high-visibility material. Must have a smooth surface so an employee does not sustain a puncture, laceration, or possibly snag their clothing. The system is properly spliced or terminated at walls, columns and posts.
When wire rope is used as a guardrail system it must be?
Toprails and midrails of guardrail systems must be at least one-quarter inch (0.6 centimeters) nominal diameter or thickness to prevent cuts and lacerations. If wire rope is used for toprails, it must be flagged at not more than 6 feet intervals (1.8 meters) with high-visibility material.
What are the OSHA requirements for guardrails?
OSHA states that guardrail must reach a height of 42 inches, plus or minus 3 inches, above the walking-working surface and withstand a force of 200 pounds at any point in a downward or outward direction. If the railing dips below 39 inches, due to the force, the railing is not OSHA compliant.
What are the requirements for guardrail systems?
Guardrail systems are capable of withstanding, without failure, a force of at least 200 pounds (890 N) applied in a downward or outward direction within 2 inches (5 cm) of the top edge, at any point along the top rail.
What are the OSHA requirements for handrails?
The top rail must be at least 42 inches in height (§1910.29(f)(1)(ii)(B)) and the handrail must be 30 to 38 inches in height (§1910.29(f)(1)(i)) (as measured at the leading edge of the stair tread to the top surface of the rail).
What is the maximum gap between handrails?
As a result, four inches would be the maximum allowable opening between the two handrails.
Can chains be used as guardrail?
OSHA does not specifically allow or prohibit chains. If used, chains must be equivalent to a guardrail, so at least two chains would be needed because a guardrail must have a top rail and mid rail. A single chain would be a violation.
