Covers and/or guardrails shall be provided to protect personnel from the hazards of open pits, tanks, vats or ditches. Skylights shall also be protected to prevent accidental falling through Ladderway floor openings shall be guarded with a standard railing with toeboards on all exposed sides (except entrance)

  7. General Requirements: Floor Opening Floor Opening Definitions Floor Opening: 12 inches or more in its least dimension, in a floor, platform, or yard, through which persons may fall. Floor Hole: less than 12 inches but more than an inch, through which materials, no persons may fall. Wall Opening: at least 30 inches high and 18 inches wide in any wall or partition through which persons may fall. Standards specific to protective devices that must be used – CFR 1910.23

  8. General Requirements: Floor Openings Floor Openings 1910.23(a)(1) Standard railing Consists of top rail, mid rail and posts. Height from the upper surface of top rail to floor level is 42 inches. Mid rail height is 21 inches. Standard toeboard 4 inches high, with not more than ¼-inch clearance above the floor.

  9. General Requirements: Wall Openings Wall Openings 1910.23(b) Opening at least 30 inches high and 18 inches wide, in a wall or partition, through which a person may fall Every wall opening from which there is a drop of more than 4 feet shall be guarded by one of the following: Rail, roller, picket fence, half door or equivalent barrier. 18" Wall Opening W x H 30" 4' Drop

  10. General Requirements: Open-Sided Floors and Platforms Open-Sided Floors and Platforms Open-sided floors or platforms 4 feet or more above adjacent floor or ground level must be guarded by a standard railing (or equivalent) on all open sides, except where there is an entrance to a ramp, stairway or fixed ladder. A toeboard is required when beneath the open sides: Persons can pass There is moving machinery There is equipment with which falling materials could create a hazard

  11. General Requirements: Stairways Stairways 1910.23(d)(1) Every flight of stairs having four or more risers shall be equipped with standard stair railings or standard handrails. Fixed Industrial Stairs: Treads must be slip resistant with uniform rise height and tread width. Must be able to carry 5 times expected load; minimum of 1000 pounds. Minimum width of 22 inches.

  12. General Requirements: Railings Railings 1910.23(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.

  13. General Requirements: Portable Ladders Portable Ladders Ladders used to gain access to a roof or other area must extend at least 3 feet above the point of support Withdraw defective ladders from service and tag or mark "Dangerous, Do Not Use“ Never use ladders in a horizontal position as scaffolds or work platforms Never use metal ladders near electrical equipment

  14. General Requirements: Portable Ladders Portable Rung and Cleat Ladders Use at an angle where the horizontal distance from the top support to the foot of the ladder is ¼ the working length of the ladder (length along the ladder between the foot and the top support)

  15. General Requirements: Fixed Ladders Fixed Ladders Permanently attached to a structure, building or equipment Cages or wells required if longer than 20 feet to a maximum unbroken length of 30 feet. Ladder safety devices may be used on tower, water tank and chimney ladders over 20 feet in unbroken length instead of cage protection

  16. General Requirements: Portable Wood Ladders Portable Wood Ladders 1910.25 All wood parts free from sharp edges and splinters Visually acceptable Stepladders 20 feet max. Single ladders 30 feet max.

  18. General Requirements: Summary Slips, trips and falls constitute the majority of general industry accidents. OSHA’s standards for walking and working surfaces include requirements for housekeeping, guarding floor and wall openings and holes, industrial stairs and ladders. Keeping working surfaces clean, dry and uncluttered can prevent many workplace accidents.
