Trainer Tips This subpart is long, a comprehensive review will require a minimum of two hours of class time Choose the applicable sections to cover based on the work environment(s) of the students Limit discussion in other areas(i.e. mobile scaffolds) The most cited areas of the subpart are found in housekeeping requirements and requirements for guarding floor and wall openings and holes
Trainer Objectives Describe Subpart D general requirements Explain the requirements for guarding floor openings and holes. Describe the requirements for stairways and railings. Identify applicable standards relating to ladders.
4 Subpart D - Walking/Working Surfaces ( ) Open-sided floors Housekeeping Wet floors Floor holes Stairways and stair platforms - Railings Standard: * * * * * *Average number of Federal OSHA citations issued between 2000 and 2003
What’s wrong with this picture?

Floor Openings (a)(5) Every pit and trapdoor floor opening, infrequently used, guarded by a floor opening cover of standard strength and construction. While the cover is not in place, the pit or trap opening constantly attended by someone or protected on all exposed sides by removable standard railings.
Clarification of as it would apply to repair pits Bus and rail car inspection and repair pits. When the pit or pits are not covered, employees walking are least 6 feet from the pit would not be in violation of 29 CFR (a)(5), provided the following actions are implemented by the employer: –The employee's safety training program will instruct employees to maintain a 6 feet clear distance from uncovered pits – Highly visible contrasting lines will be installed 6 feet from the edge of pits –Employer will install caution signs and ensure compliance by employees
Floor Openings (a)(7) Every temporary floor opening shall have standard railings, or shall be constantly attended by someone.
Floor Openings (a)(8) Every floor hole into which persons can accidentally walk shall be guarded by either: –(i)A standard railing with standard toeboard –(ii)A floor hole cover of standard strength and construction. While the cover is not in place, the floor hole shall be constantly attended by someone or shall be protected by a removable standard railing. Floor opening large enough to fall through
Floor Openings (a)(10) Where doors or gates open directly on a stairway, a platform shall be provided, and the swing of the door shall not reduce the effective width to less than 20 inches.
Wall Openings (b) (1)Every wall opening from which there is a drop of more than 4 feet shall be guarded by one of the following: –(i)Rail, roller, picket fence, half door, or equivalent barrier. 30" 18" 4' Wall Opening W x H Drop
Every open-sided floor or platform 4 feet or more guarded on all open sides except where there is entrance to a ramp, stairway, or fixed ladder. Open-sided Floors (c)(1)
The railing shall be provided with a toeboard wherever, beneath the open sides, –(i)Persons can pass, –(ii)There is moving machinery, –(iii)There is equipment with which falling materials could create a hazard
Open-sided Floors (c)(3) All open-sided floors, walkways, platforms, or runways above or adjacent to dangerous equipment, guarded with a standard railing and toe board Equipment traverses over wiring pit opening
Stairways (d)(1) Every flight of stairs having four or more risers shall be equipped with standard stair railings or standard handrails.
Railings (e)(1) A standard railing consists of top rail, intermediate rail, and posts Have a vertical height of 42 inches nominal from upper surface of top rail to floor. The top rail smooth-surfaced The ends of the rails shall not constitute a projection hazard
09/16/ Clarification of our railing requirements in 29 CFR (e) Other types, sizes, and arrangements of railing construction are acceptable provided they meet the following conditions: –A smooth-surfaced top rail at a height above floor, platform, runway, or ramp level of 42 inches nominal;
09/16/ Clarification of our railing requirements in 29 CFR (e) –A strength to withstand at least the minimum requirement of 200 pounds top rail pressure; –Protection between top rail and floor, platform, runway, ramp, or stair treads, equivalent at least to that afforded by a standard intermediate rail.
Directives STD Height of Guardrails in General Industry Applications OSHA Regional Administrators/Area Directors shall classify technical violations of 29 CFR (e)(1) as de minimis violations, where the employer has provided guardrails which meet the following specifications:
Directives STD Height of Guardrails in General Industry Applications 1. Existing guardrailing shall consist of a top rail, intermediate rail, and posts, or equivalent, and shall have a minimum vertical height of 36 inches to 44 inches from the upper surface of the top rail to the floor, platform, runway or ramp level. 2. Guardrailings with heights greater than 44 inches are permissible provided the extra height does not create a dangerous situation for employees. Openings beneath the top rail that would permit the passage of a 19 inch or larger spherical object would create an unsafe condition, therefore, additional mid-rails may be necessary
30" - 34" A stair railing shall be not more than 34 inches nor less than 30 inches from upper surface of top rail to surface of tread in line with face of riser at forward edge of tread. Railings (e)(2)
Railings (e) (i)Wood railings, posts at least 2 by 4 (i)Posts < 6 feet (i)Rails, at least 2 by 4 (ii)Pipe railings at least 1 1/2 inches nominal diameter (ii)Posts spaced not more than 8 feet on centers.
Railings (e) For structural steel railings –(iii)Posts and top and intermediate rails 2 by 2 by 3/8 inch angles –(iii)Posts spaced not more than 8 feet on centers.
Railings (e)(iv) The completed structure shall be capable of withstanding a load of at least 200 pounds applied in any direction at any point on the top rail. 200 lb.
Railings (e)(4) A standard toeboard 4 inches nominal in vertical height Securely fastened Not more than 1/4-inch clearance above floor level. Openings not over 1 inch 1" max 1/4" max Floor level
Railings (e)(4) Where material is piled to such height that a standard toeboard does not provide protection, paneling from floor to intermediate rail, or to top rail shall be provided.
Fixed Stairs (b) Provided for regular travel between levels Where equipment requires attention routinely Fixed stairs provided where access to elevations is daily For work around acids, caustics, gases, or other harmful substances
Standard Interpretations 04/27/ Minimum width of means of egress; The OSHA egress requirements, § (f)(6), state that the minimum width of any way of exit access shall in no case be less than 28 inches and the OSHA stair requirement, § (d), requires a minimum stair width of 22 inches. Is an employer out of compliance with this egress standard if the stairs are 22 inches in width? Reply: Yes, if the stair is a means of egress component (the exit access, the exit itself, or exit discharge). All stairs, and other approved egress components, must meet the Subpart E, Means of Egress standards.
