During

Position Ladders Correctly

  • Keep the area around the top and bottom of a ladder clear.
  • When using a ladder in a crowded area, erect warning signs or barricades to guide traffic away from the foot of the ladder. If this is not possible, have someone hold and guard the bottom of the ladder.
  • Rest the base of ladder on a spot away from hallways, passageways, doorways, driveways or heavy traffic areas. Never set up a ladder in front of a door unless the door is locked or a guard is posted.
  • Rest the base of ladders on firm, level, dry, non slippery surfaces. If one foot sits in a low spot, build up the surface with firm material or use leg levelers or mudsills when necessary to provide firm support.
  • Make sure the ladder is sitting straight and secure before climbing it. Do not allow ladders to lean sideways. Level them before using.
  • Position the extension ladder such that top section is above and resting on the bottom section with the rung locks engaged.
  • To provide the correct angle so extension ladders won’t slip, place the base of the ladder one foot away from whatever the top of the ladder leans against, for every four feet in height of the ladder.
  • To check, put your feet at the base of the ladder and extend your arm straight out. If you can touch the closest part of the ladder without bending your arm, or bending over, the ladder is at the correct angle. If not, the ladder is not at a safe angle.
  • Do not try to make a ladder reach farther by setting it on boxes, barrels, bricks, blocks or other unstable bases.
  • Never set up or use a ladder in a high wind, especially a lightweight metal or fiberglass type. Wait until the air is calm enough to ensure safety.
  • Do not use ladders on ice or snow unless absolutely necessary. If they must be used on ice or snow, use spike or spur-type safety shoes on the ladder feet and be sure they are gripping properly before climbing.
  • When two or more separate ladders are used to reach an elevated work area, make sure that the ladders are offset with a platform or landing between the ladders.

Secure Ladders Properly

  • The ladder shall be so placed as to prevent slipping, or it shall be tied, blocked, held, or otherwise secured to prevent slipping. One way to prevent slipping is to use safety shoes on ladder feet.
  • Brace the foot of the ladder with stakes or place stout boards against the feet if there is any danger of slipping.
  • Tie, block or otherwise secure the ladder to prevent it from being displaced.
  • Make sure that the top support is supported equally on the two rails, unless a single support attachment is provided and used.
  • Top support for a ladder is as important as good footing. The top should rest evenly against a flat, firm surface. If a ladder is to be leaned against a surface, test the surface first for strength and stability.

Maintain Overlap in Extension Ladders


While using extension ladders, make sure that you are always maintaining at least the minimum required overlap between the sections of the ladder. The minimum overlap lengths are:
Ladder Size (Feet) Minimum Overlap (Inches)
Up to and including 32 36
Over 32, up to and including 36 46
Over 36, up to and including 48 58
Over 48, up to and including 60 70

Climb and Work Safely on Ladders

  • While climbing and working on ladders, you need to climb or work with the body near the middle of the step or rung to keep the load on the ladder centered.
  • Make sure that you do not overreach from the center position. To avoid overreaching, you need to descend and reposition the ladder.
  • When it is not practical to work with the body near the middle of the step or rung, you need to secure the ladder at the top, and use a personal fall protection system.
  • Always face the ladder and maintain contact with the ladder at three-points at all times. Contact with the ladder at three points means two feet and one hand, or two hands and one foot which is safely supporting the user’s weight.
  • Do not carry equipment or materials on ladders. Have coworkers hand up tools and equipment instead of carrying them when on a ladder.
  • Make sure that you are not standing and working on the top 3 rungs of a single or extension ladder. If you have to work from the top 3 rungs, ensure that there are structures that provide you with a firm handhold or you use a personal fall protection system.
  • Do not stand on the top cap or the step below the top cap of a step ladder.
  • Do not use cross-bracing on the rear section of step ladders for climbing.
  • Ladders shall not be moved, shifted, or extended while in use, unless permitted by the manufacturer.
  • Always follow manufacturer’s recommendations for proper use.

Follow Safe Work Practices

Following safe work practices like these given below can save your employees from the accidents and injuries while climbing and using ladders in workplace.
  • Get help when needed. DO NOT try to do alone if you can’t do it safely by yourself.
  • DO NOT take short cuts.
  • Use ladder only for the purpose it is made for.
  • Read and follow all labels/markings on the ladder.
  • Never use a ladder when under the influence of alcohol, on drugs or medication, or in ill health.
  • If you get sick, dizzy or panicky while on a ladder, do not try to climb down in a hurry. Wait. Drape your arms around the rungs and rest your head against the ladder until you feel better. Then climb down slowly and carefully.
  • Allow only one person at a time on a ladder unless the ladder is specifically designed to hold more than one person at a time (e.g., double sided or mechanics ladders).
  • Never use a ladder on a scaffold platform. If you need to reach higher, the scaffold should be higher.
  • DO NOT use step ladders as single ladders or in a partially closed position.
  • Be sure that all locks on an extension ladder are properly engaged.
  • Always open a stepladder completely and make sure the spreader is locked open before using the ladder.
  • Never slide down a ladder.
  • Never climb onto a ladder from the side, from above the top or from one ladder to another.
  • Do not straddle the front and back of a stepladder.
  • Ladders shall not be used in a horizontal position as platforms, runways, or scaffolds unless designed for such use.
  • DO NOT use ladders as a brace, skid, guy or gin pole, gangway, or for uses other than they were intended.
  • DO NOT use wooden ladders that are painted.
  • Never tie or fasten ladders together to gain additional length/height.
  • Avoid overhead electrical hazards. Look for overhead power lines before handling a ladder. Avoid using a metal ladder near power lines.
  • Never use metal ladders around exposed electrical wiring. Metal ladders should be marked with tags or stickers reading “CAUTION-Do Not Use Around Electrical Equipment” or similar wording.
  • Use only the non-conductive ladders in wet and damp locations where electrical work is anticipated.
  • Wear shoes with slip resistant soles.
  • Clean mud and other slippery substances off your shoes and ladder rungs before climbing the ladder.
  • When moving an extension ladder always retract the “fly” section(s).
  • When carrying an extension ladder keep the bottom section lower than the top. Use a ladder dolly to help you carry heavy ladders.
  • When using extension ladders consider using fall protection systems
