To strengthen guardrails, reduce the spacing of posts to between 1 and 2 metres (3 feet 4 inches and 6 feet 8 inches) and double the 2 x 4 top tail. Posts on wooden guardrails must not be further apart than 2.4 metres (8 feet).
What is the maximum distance allowed between guardrail posts?
OSHA requires guardrail posts to be spaced no more than 8-feet apart on center, no matter if it’s wood, pipe railing, or structural steel. If posts are spaced more than 8-feet on center, it will no longer be OSHA compliant.
What is the maximum distance a guardrail system should be installed from the exposed edge that it is protecting from?
Guardrails should be installed as close to the edge as possible — no further away than one foot (30 cm) — and must be capable of resisting any load likely to be applied.
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 is the OSHA standard 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).
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.
What is the minimum gap between handrails?
2.25 inches
The minimum clearance between handrails and other objects is 2.25 inches. Handrails have the shape and dimension necessary to grasp firmly. Ends of handrail and systems do not present any projection hazards.
What vertical drop is allowed when using a travel restraint system?
A fall-restricting system is designed to limit a workerʼs free-fall distance to 0.6 metres (2 feet).
What is the maximum distance a safety net may be installed under a walking working surface?
30 feet
Safety nets shall be installed as close as practicable under the walking/working surface on which employees are working, but in no case more than 30 feet (9.1 m) below such level. When nets are used on bridges, the potential fall area from the walking/working surface to the net shall be unobstructed.
How far above the working platform must the top rail of a scaffold guardrail be?
between 900mm and 1.07m
Edge protection must be provided as close as possible on the gable ends. The top rail should be between 900mm and 1.07m above the line of the gable (slope of the roof). If the work performed on the roof is weatherproofing, a toe board is not required but is recommended.
What is the OSHA recommended maximum single person lift?
51 pounds
The lifting equation establishes a maximum load of 51 pounds, which is then adjusted to account for how often you are lifting, twisting of your back during lifting, the vertical distance the load is lifted, the distance of the load from your body, the distance you move while lifting the load, and how easy it is to hold
What is the vertical height of a standard railing?
42 inches
Railing, toe boards, and cover specifications. (1) A standard railing shall consist of top rail, intermediate rail, and posts, and shall have a vertical height of 42 inches nominal from upper surface of top rail to floor, platform, runway, or ramp level.
How much weight can a railing support?
Guardrail systems must be capable of withstanding at least 200 pounds of force applied within 2 inches of the top edge, in any direction and at any point along the edge, and without causing the top edge of the guardrail to deflect downward to a height less than 39 inches above the walking/working level.
Can you tie off to a guardrail?
OSHA has determined that when a standard guardrail is not feasible because it would result in impairment of the work being performed alternate protection may be provided for employees. A tie-off system is acceptable as a method of meeting the intent of Section 1910.23(c)(1).
How far apart should deck railing posts be?
U.S. building code requires support posts for the rail structure to be no further apart than 6 feet on a deck with 4×4′ deck rail posts and no more than 8 feet apart for decks with 6×6′ deck rail posts. Posts should be no further apart than 5.5 feet on stairs.
What is the minimum distance a 10 foot scaffold plank should extend over its supports if it is not cleated or otherwise restrained from movement?
12 inches
Each end of a platform 10 feet or less in length shall not extend over its support more than 12 inches (30 cm) unless the platform is designed and installed so that the cantilevered portion of the platform is able to support employees and/or materials without tipping, or has guardrails which block employee access to
What is the minimum horizontal distance a safety net shall be place from the edge of a work surface when the safety net is 7 fee below the work surface?
Nets shall extend 8 feet beyond the edge of the work surface where employees are exposed and shall be installed as close under the work surface as practical but in no case more than 25 feet below such work surface.
What is the maximum fall height of the safety net?
6 m
Safety nets can be used with a maximum falling height up to 6 m (3 m within 2 m of the edge). Install the Safety net as close as possible to the working level, preferably within 2 m.
What is the difference between a handrail and a guardrail?
Defining Guardrails and Handrails
OSHA and many building codes use the term “guardrail” to refer to fall protection for raised platforms and stairways, but the industrial safety industry uses the more specific term “handrail,” with “guardrail” used only to refer heavy-duty beams of formed steel.
How long should a stair rail be?
Measuring Handrail Length
ADA compliant stair handrails, mandatory in commercial settings, must run the full length of the Nosing Line. In addition, they require a 12” horizontal section at the top, starting at a point directly above the upper nosing.
What is the maximum height of a handrail on a stairway?
38 inches
The current ADA standards dictate that the top of Handrails gripping surfaces shall be 34 inches minimum and 38 inches maximum measured vertically above walking surfaces, stair nosings, and ramp surfaces with a greater than a 1:20 slope.
