when discussing safety standards for mezzanines or raised platforms in a warehouse environment, the main issue is minimizing the risk of falls, which is the most common cause of serious work-related injuries and deaths. oshas mezzanine safety requirements are defined under standard 1910, subpart d walking-working surfaces.
work platforms. designed to increase productivity while reducing the risk of back injuries and fatigue, a work platform is able to raise or lower a worker to the optimal working height. work platforms are essential for packing and assembly stations, hvacr installations and when using heavy machinery such as drill presses, lathes and saws.
for purposes of this subpart, a scaffold does not include a crane-suspended or derrick-suspended personnel platform or a rope descent system. ship stair ship ladder means a stairway that is equipped with treads, stair rails, and open risers, and has a slope that is between 50 and 70 degrees from the horizontal.
platform lifts wheelchair lifts permitted by 4.1 shall comply with the requirements of 4.11. 4.11.2* other requirements. if platform lifts wheelchair lifts are used, they shall comply with 4.2.4 , 4.5 , 4.27 , and asme a17.1 safety code for elevators and escalators, section xx, 1990.
ramp runs must have a clear width of 36 minimum measured between handrails where provided . the width of ramps that are part of a means of egress may further be determined by applicable life safety codes and requirements for minimum exit widths greater than 36.
'railings and handrails.' standard railings shall be provided on the open sides of all exposed stairways and stair platforms. handrails shall be provided on at least one side of closed stairways preferably on the right side descending. stair railings and handrails shall be installed in accordance with the provisions of 1910.23.
guardrail specifications and defects: requirements for guard railings at stair platforms, landing guard railings and other elevated walkways. guardrail guide: stair landing, porch, deck and walkway guardrail specifications and codes: height, dimensions, spacing, construction, photos and sketches of guardrail defects and safety hazards.
raised platform handrail requirements section 13 walking and working surfaces material and strength requirements must equal the stair railing. mount the handrail with a minimum 1-1/2-inch clearance from any obstruction. handrails must provide an adequate handhold for employees grasping them to avoid falling.
deck railing height: requirements and codes for ontario . railing requirements in the ontario building code a guardrail is used to prevent somebody from falling off a raised platform. however, it can double as support similar to the function of the handrail. requirements for handrails in ontario: osha fall protection requirements in general industry
osha railing requirements for load: railings must meet a 200-lb concentrated load. warning: given this load requirement, it is highly unlikely that you can achieve a 6 foot span for a wood railing or an 8 foot span on steel or pipe railings.
any work area four feet or more above the next level lower must have guardrails. period. the guardrails must be on every open side of the platform, excluding openings. the only time railing is not required is when the platform is up against another vertical surface like the side of a helicopter .
the area in question is one corner at the interior of the building where a raised platform is proposed that is 2 ft above the multipurpose main floor. steps on both sides of the platform are proposed as shown. questions: q1 are handrail required at the three locations circled in red?
upright posts or panels must be installed to leave gaps no wider than 19 inches. the purpose of these requirements is to prevent workers from slipping between the rails and the floor.
these requirements are dependent upon stairway width and the number of closed sides for every flight of stairs having four or more risers. for example, on a stairway more than 44 inches wide but less than 88 inches wide, there must be one handrail on each enclosed side and one stair railing on each open side.
these options added to a raised platform can makeup a safe gangway or raised walkway to access machinery or service areas that are hard to reach safely. modular steps and prefabricated metal stairs with landing platforms can be configured and custom painted to fit any number of entrance and exit requirements in your choice of colors.
e crossovers, elevated walkways, elevated ramps, and stairways shall be of substantial construction, provided with handrails, and maintained in good condition. where necessary, toeboards shall be provided. f crossovers shall be provided where it is necessary to cross conveyors.
the following is based on the 2006 ibc: structural capacities: handrails, guardrails, and their supports must be designed for 50 lbs per linear foot, applied in any direction at the top of the top rail, and a concentrated load of 200 lbs applied in any direction at any location along the top of the top rail.
5.7 raised platforms. in banquet rooms or spaces where a head table or speaker's lectern is located on a raised platform, the platform shall be accessible in compliance with 4.8 or 4.11. open edges of a raised platform shall be protected by placement of tables or by a curb. 5.8 vending machines and other equipment.
osha 1910.29 b contains system requirements that employers must follow to ensure guardrail systems will protect workers from falling to lower levels: 1910.29 b 1 the top edge height of top rails, or equivalent guardrail system members, are 42 inches 107 cm , plus or minus 3 inches 8 cm , above the walking working surface.
the railing shall be provided with a toeboard where the platform, runway, or ramp is 6 feet or more above places where employees normally work or pass and the lack of a toeboard could create a hazard from falling tools, material, or equipment.
preventing slips is an effective way to prevent falls. to be in compliance with osha catwalk requirements, all catwalks and raised work platforms must have toeboards at least 3 1/4 inches tall along all open sides. this is to prevent falling tools and materials from injuring workers below.
