When a guardrail system is used, the guardrail height must be increased in height equal to the height of the stilts. This section does not apply to aerial lifts, the criteria for which are set out exclusively in 1926.453. When vertical lifelines are used, they shall be fastened to a fixed safe point of anchorage, shall be independent of the scaffold, and shall be protected from sharp edges and abrasion. The top edge height of toprails or equivalent member on supported scaffolds manufactured or placed in service after January 1, 2000 shall be installed between 38 inches (0.97 m) and 45 inches (1.2 m) above the platform surface. Steps and rungs of ladders and stairways must line up vertically with each other between rest platforms.

Wood platforms shall not be covered with opaque finishes, except that platform edges may be covered or marked for identification. [29 CFR 1926.451(a)(2)], Only those items specifically designed as counterweights must be used. Guardrail systems installed to meet the requirements of this section shall comply with the following provisions (guardrail systems built in accordance with Appendix A to this subpart will be deemed to meet the requirements of paragraphs (g)(4)(vii), (viii), and (ix) of this section): Guardrail systems shall be installed along all open sides and ends of platforms. Excess suspension wire rope and any additional independent lines from grounding shall be insulated; The suspension wire rope shall be covered with insulating material extending at least 4 feet (1.2 m) above the hoist. Suspension ropes shall be shielded from heat-producing processes. Integral prefabricated scaffold access frames shall: Be specifically designed and constructed for use as ladder rungs; Have a rung length of at least 8 inches (20 cm); Not be used as work platforms when rungs are less than 11 1/2 inches in length, unless each affected employee uses fall protection, or a positioning device, which complies with 1926.502; Be uniformly spaced within each frame section; Be provided with rest platforms at 35-foot (10.7 m) maximum vertical intervals on all supported scaffolds more than 35 feet (10.7 m) high; and. Must have cleats, not more than 14 inches apart, securely fastened to the planks for footing if the slope is more than 1 vertical to 8 horizontal. Must be positioned so as not to tip the scaffold.

Stairways must be installed between 40 degrees and 60 degrees from the horizontal. [29 CFR 1926.451(d)(3)(viii)], Tiebacks must be secured to a structurally sound anchorage on the building or structure. [29 CFR 1926.451(d)(13)], The stall load of any scaffold hoist must not exceed three times its rated load. Scaffolds and scaffold components shall not be loaded in excess of their maximum intended loads or rated capacities, whichever is less. Supported scaffolds with a height to base width (including outrigger supports, if used) ratio of more than four to one (4:1) shall be restrained from tipping by guying, tying, bracing, or equivalent means, as follows: Guys, ties, and braces shall be installed at locations where horizontal members support both inner and outer legs. WORKERS MUST USE FALL PROTECTION WHEN WORKING FROM THIS SCAFFOLD Green: SCAFFOLD IS OK FOR USE Tag must include the scaffold capacity: Are there requirements for suspension ropes? Work on or from scaffolds is prohibited during storms or high winds unless a competent person has determined that it is safe for employees to be on the scaffold and those employees are protected by a personal fall arrest system or wind screens. Hook-on and attachable ladders shall have uniformly spaced rungs with a maximum spacing between rungs of 16 3/4 inches. [, When employees are plastering and lathing 18 inches (46 cm) or less from the front edge. This basically means that the ladder rungs should have sufficient clear space behind them to allow a foot or hand to make sufficient purchase on the rung. Construction materials such as, but not limited to, masonry units and rolls of roofing felt, shall not be used as counterweights. WebAccess points may be designed for access or be opportunistic. Sand, gravel and similar materials that can be easily dislocated shall not be used as counterweights. Do employees working on supported scaffolds need to be trained? Note to paragraph (b)(2)(i): Pursuant to an administrative stay effective November 29, 1996 and published in the Federal Register on November 25, 1996, the requirement in paragraph (b)(2)(i) that roof bracket scaffolds be at least 12 inches wide is stayed until November 25, 1997 or until rulemaking reguarding the minimum width of roof bracket scaffolds has been completed, whichever is later. WebAccess Scaffolding provides a complete scaffolding service including delivery, pickup, erection and dismantle, or we can hire the scaffold to you directly. At all points of a scaffold where the platform changes direction, such as turning a corner, any platform that rests on a bearer at an angle other than a right angle shall be laid first, and platforms which rest at right angles over the same bearer shall be laid second, on top of the first platform. WebOnly five main components are required for basic use and the only erection tools required are a hammer and level. Except as provided in paragraphs (b)(3)(i) and (ii) of this section, the front edge of all platforms shall not be more than 14 inches (36 cm) from the face of the work, unless guardrail systems are erected along the front edge and/or personal fall arrest systems are used in accordance with paragraph (g) of this section to protect employees from falling. Scaffolds and scaffold components shall be inspected for visible defects by a competent person before each work shift, and after any occurrence which could affect a scaffold's structural integrity. When other types of hoists are used, the suspension ropes shall be long enough to allow the scaffold to be lowered to the level below without the rope end passing through the hoist, or the rope end shall be configured or provided with means to prevent the end from passing through the hoist. Two tie-backs installed at opposing angles are required when a perpendicular tieback cannot be installed. When scaffold platforms are more than 2 feet (0.6 m) above or below a point of access, portable ladders, hook-on ladders, attachable ladders, stair towers (scaffold stairways/towers), stairway-type ladders (such as ladder stands), ramps, walkways, integral prefabricated scaffold access, or direct access from another scaffold, structure, personnel hoist, or similar surface shall be used. Scaffolds are commonly used in construction work so workers have a safe, stable work On scaffolds where platforms are overlapped to create a long platform, the overlap shall occur only over supports, and shall not be less than 12 inches (30 cm) unless the platforms are nailed together or otherwise restrained to prevent movement. Ropes shall be inspected for defects by a competent person prior to each workshift and after every occurrence which could affect a rope's integrity. insulated protective covers cover the hoist. Each end of a platform, unless cleated or otherwise restrained by hooks or equivalent means, shall extend over the centerline of its support at least 6 inches (15 cm). Stairrails shall be not less than 28 inches (71 cm) nor more than 37 inches (94 cm) from the upper surface of the stairrail to the surface of the tread, in line with the face of the riser at the forward edge of the tread. If there is a tail line below the hoist, it shall be insulated to prevent contact with the platform. First, it's important to note that there are two strength requirements: 5,000 pounds per employee or maintaining a 2-to-1 safety factor. Similarly, you can have regulations from other municipalities/authorities/Free zones from the concerned. Stilts may be used on a large area scaffold. The ends of all rails shall not overhang the terminal posts except when such overhang does not constitute a projection hazard to employees.
