An opening in the floor is considered a hole when it is more than 24 in. True False Stairway openings do not need fall protection. True False Railings in Subpart D must withstand 800 lbs. thrust in any direction. True False The vertical posts of railings must be at 20 ft. centers. True False Fixed stairs must have a minimum width of 22 in. True False Subpart D Test Circle the appropriate answer and locate appropriate standard QuestionStandard (e)(3)(iv) (e)(3)(i) & (ii) & (iii) (a)(1) (a)(1) (d)
Part 1910 Subpart D - Walking- Working Surfaces Definitions General requirements Guarding floor and wall openings and holes Fixed industrial stairs Portable wood ladders Portable metal ladders Fixed ladders Safety requirements for scaffolding Manually propelled mobile ladder stands and scaffolds (towers) Other working surfaces.
Open sided Floors Housekeeping Stair rails - 93 Floor holes (c)(1) 22(a)(1) 24(h) 23(a)(8) Subpart D - Walking/Working Surfaces ( ) Number of Serious Violations - FY 98 Wet Floors (a)(1)
(a)(1) & (a)(2) - Floor hole vs floor opening
(a)(1) All places of employment, passageways, storerooms, service rooms shall be kept clean and orderly and in a sanitary condition.
Debris on floor
(a)(2) - Floors Where wet processes are used, keep floors clean and dry as possible
(a)(3) - Protruding nails
(b) - Aisles and passageways (1) Safe clearances; clean and good repair; no obstacles in aisles where mechanical handling equipment is used. (2) Aisles and passageways shall be permanently marked
(d) - Floor loading protection (1) Loads approved by building official shall be marked.

Guarding floor and wall openings and holes
Guard Rail System Top Rail Mid Rail Toe Board (a)- Protection for floor openings (1) Every stairway floor opening shall be guarded by a standard railing constructed in accordance with paragraph (e) of this section.
Types of materials
(a)(2) - Ladderway floor openings, platforms - Guarded by standard railing, toeboard
(a)(3) Hatchway/chute floor opening Guarded by hinged cover or removable railing/toeboard
(a)(4) Skylight floor opening Guarded by standard skylight screen/or fixed standard railing
Protected sky light
(a)(6) Manhole floor opening - Guarded by standard manhole cover
(a)(8) Floor hole opening - Guarded by standard railing/cover
(a)(8)(ii) - Floor hole opening
(b) - Wall openings/holes (1) Drop greater than 4’ shall be guarded
(c)(1) Open sided floors, platforms and runways
Elevated runway Runway
Adequate platform guardrail
What’s the problem here? No toe board
What’s up with this???
(c)(3) Adjacent to dangerous equipment (regardless of height) - Guarded by standard railing with toeboard Open screw auger directly underneath
(d) Stairway railings and guards
(d)(1) Stairway railings and guards 4 or more risers require standard stair railings or handrails
(d)(1)(i) Stairways less than 44” wide - At least one handrail
(d)(1)(ii) Less than 44” wide with one open side - At least one railing on open side
(d)(1)(iii) Less than 44” wide with both open sides - Stair railing on each side
What’s wrong with this picture?
(e)(3)(iv) The anchoring of posts and framing of members for railings of all types - Capable of withstanding a load of at least 200 pounds applied in any direction at any point on the top rail.
Fixed Industrial Stairs
(c) Stair strength Must carry 5 times normal live load anticipated, but never less than 1000 pounds moving concentrated load
(h) Standard railing on open sides of all exposed stairways and stair platforms Hand rails provided on at least one side of closed stairways (i) Vertical clearance above stair tread to overhead obstruction - At least 7 feet
