29 CFR 1910.25 - Portable wood ladders.
(a) Application of requirements. This section is intended to prescribe rules and establish minimum requirements for the construction, care, and use of the common types of portable wood ladders, in order to insure safety under normal conditions of usage. Other types of special ladders, fruitpicker's ladders, combination step and extension ladders, stockroom step ladders, aisle-way step ladders, shelf ladders, and library ladders are not specifically covered by this section.
(b) Materials -
(1) Requirements applicable to all wood parts.
(i) All wood parts shall be free from sharp edges and splinters; sound and free from accepted visual inspection from shake, wane, compression failures, decay, or other irregularities. Low density wood shall not be used.
(c) Construction requirements.
(i) General requirements.
(c) The minimum width between side rails at the top, inside to inside, shall be not less than 11 1/2 inches. From top to bottom, the side rails shall spread at least 1 inch for each foot of length of stepladder.
(d) -(e) [Reserved]
(f) A metal spreader or locking device of sufficient size and strength to securely hold the front and back sections in open positions shall be a component of each stepladder. The spreader shall have all sharp points covered or removed to protect the user. For Type III ladder, the pail shelf and spreader may be combined in one unit (the so-called shelf-lock ladder).
(3) Portable rung ladders.
(ii) Single ladder.
(a) Single ladders longer than 30 feet shall not be supplied.
(iii) Two-section ladder.
(a) Two-section extension ladders longer than 60 feet shall not be supplied. All ladders of this type shall consist of two sections, one to fit within the side rails of the other, and arranged in such a manner that the upper section can be raised and lowered.
(iv) Sectional ladder.
(a) Assembled combinations of sectional ladders longer than lengths specified in this subdivision shall not be used.
(v) Trestle and extension trestle ladder.
(4) Special-purpose ladders.
(ii) Painter's stepladder.
(a) Painter's stepladders longer than 12 feet shall not be supplied.
(a) Mason's ladders longer than 40 feet shall not be supplied.
(5) Trolley and side-rolling ladders -
(d) Care and use of ladders -
(1) Care. To insure safety and serviceability the following precautions on the care of ladders shall be observed:
(i) Ladders shall be maintained in good condition at all times, the joint between the steps and side rails shall be tight, all hardware and fittings securely attached, and the movable parts shall operate freely without binding or undue play.
(ii) Metal bearings of locks, wheels, pulleys, etc., shall be frequently lubricated.
(iii) Frayed or badly worn rope shall be replaced.
(iv) Safety feet and other auxiliary equipment shall be kept in good condition to insure proper performance.
(xi) Rungs should be kept free of grease and oil.
(2) Use. The following safety precautions shall be observed in connection with the use of ladders:
(i) Portable rung and cleat ladders shall, where possible, be used at such a pitch that the horizontal distance from the top support to the foot of the ladder is one-quarter of the working length of the ladder (the length along the ladder between the foot and the top support). The ladder shall be so placed as to prevent slipping, or it shall be lashed, or held in position. Ladders shall not be used in a horizontal position as platforms, runways, or scaffolds;
(ii) Ladders for which dimensions are specified should not be used by more than one man at a time nor with ladder jacks and scaffold planks where use by more than one man is anticipated. In such cases, specially designed ladders with larger dimensions of the parts should be procured;
(iii) Portable ladders shall be so placed that the side rails have a secure footing. The top rest for portable rung and cleat ladders shall be reasonably rigid and shall have ample strength to support the applied load;
(v) Ladders shall not be placed on boxes, barrels, or other unstable bases to obtain additional height;
(ix) Short ladders shall not be spliced together to provide long sections;
|Size of ladder (feet)||Overlap (feet)|
|Up to and including 36||3|
|Over 36 up to and including 48||4|
|Over 48 up to and including 60||5|
(xix) The user should equip all portable rung ladders with nonslip bases when there is a hazard of slipping. Nonslip bases are not intended as a substitute for care in safely placing, lashing, or holding a ladder that is being used upon oily, metal, concrete, or slippery surfaces;
(xx) The bracing on the back legs of step ladders is designed solely for increasing stability and not for climbing.
