Supportive Information:
1. No person shall use a ladder without having received ladder training2. Caretaking staff may climb up to 8 feet (2.5 meters) only, unless authorized by supervisor3. Work requiring a ladder over 12 ft tall requires 2 workers4. Only CSA Grade 1 or better ladders are to be use
Purpose
Provide guidance and information relating to the minimum standard of safe work practice to reduceinjury while working with ladder
IntroductionLadders are commonly used to reach or to gain access to higher areas/levels andsometime from which to perform work. There are a number of hazards associated withladderuse that can cause accidents resulting in serious injuries. These potentialinjuries include:
• Falling from ladders (especially when getting on/off or contact with electricity)• Struck by objects or by ladder (falling ladder or when carrying ladders)• Tripping over ladders• Muscle strain from carrying heavy ladders
Causes of ladder accidents include:
• Ladder not secured in place• Slippery surfaces (feet, rungs, footwear)• Improper angle• Improper set-up - not spreading ladder legs and spreader bars.• Poor grip• Unsafe position on ladder (reaching, climbing too high)• Defective/damaged ladder• Ladder positioned too close to electrical lines• Using ladder in high winds

Working from ladders poses the risk of falling and the decision to use a ladder fromwhich to work should be considered the least desirable method. Safer alternate methodssuch as performing work from stairs, scaffolding or elevating platforms should beconsidered first. Except for work of short duration that can be done safely from aladder, work will be done with a scaffold or elevated work platform; this will bedetermined and documented with a JHA by the individuals performing the workltask

Method
The method used to reduce the risk of incidents involving ladders is based on the rigorousapplication of risk management principles combined with education and training including:
• compliance with applicable legislation;• risk identification;• risk assessment;• identification and implementation of treatments;• communication and review of procedures;• training and education; and• actions and considerations following an incident.
This document describes different ladder types and outlines the procedures forproper selection and safe use of portable ladders.
TYPES OF LADDERS
LADDER TYPES
Ladders may be fabricated from wood, aluminum or fiberglass and they come indifferent shapes and heights or lengths. Selecting the proper ladder depends on theparticular task at hand. Ladder types include:
• Straight• Extension• Sectional• Hooked• Trestle and extension trestle- Platform (best choice if working from ladder)

GENERAL LADDER SELECTION AND SAFE USE PROCEDURES
1) Ladder Selection
Working from ladders poses the risk of falling and the decision to use a ladderfrom which to work should be considered the least desirable method. Except for workof short duration that can be done safely from a ladder, work will be done with ascaffold or elevated work platform; this will be determined and documented with a JHAby the individuals performing the workltaskWhen selecting a ladder:
A) Select the most appropriate type of ladder for the task to be performed• Step• Straight• Extension• Platform
B) Select most appropriate material (PP is fading out aluminum & wood ladders)- Aluminum• Fiberglass (only use fiberglass near electrical equipment)• Wood
C) Select proper ladder height to:• Position yourself so you don’t have to stand on the upper rungs!• Check for overhead power lines!• See chart (voltages and distance)• Use fiberglass when working on or near electrical conductors
2) Inspect Ladders Prior to UseBefore using a ladder, be sure to inspect it to ensure it is in good working condition andsafe to use. Inspect ladders for:
• Defects such as broken or missing rungs, cleats, safety feet or rails.• Slippery substances on wngs• Stability• Inspect for structural integrity
V Joints should be fight and secureV Hardware and fittings should be secure, not damaged or corrodedV Moveable parts should operate freelyV Check side rails and rungs for signs of damage, cracks, fraying (fiberglass)V Test rung locks (extension ladders)V Check ropes, cables and pulleys
Damaged or defective ladders must be immediately removed from service andnot used.
3) Set-Up• Check the work and surrounding areas for hazards such as overhead wires, slippery or
uneven surfaces, traffic etc...• Ensure the area at base and top of ladder is free/clear of obstructions• Ensure ground/surface is firm and level
Keep metal and wood ladders away from power lines and other live conductors

UNIVERSITY0 OF MANITOBA
PHYSICAL PLANT Safe Work Practice # 1.6.1Safe Ladder Use
• Place ladders on firm, level ground• Position ladder at proper angle (straight and extension) and secure in position.• Open ladder fully (step ladder)• Take appropriate measures to protect the base of the ladder from any activity that could
bang it (e.g. people, doors, vehicles).
V Have someone guard or block the area while work is being performed on theladder
V Post warning signs or use pylons if necessary
4) Safe Climbing and Use
• Caretaking staff may climb up to 8 feet (2.5 metersl only, unless authorized by supervisor
• Work requiring a ladder over 12 ft tall requires 2 workers• Only one person is permitted on a ladder at the same time- Do not overreach• Always face the ladder and keep your hips (center of gravity)
between the rails• Maintain 3-point contact with ladders (1 hand and 2 feet or
2 hands and 1 foot) when climbing or descending ladders.• Keep hands free when climbing ladders. Use a tool belt
or rope to raise tools.• Ensure soles of shoes are clean and not slippery• Never climb a damaged, bent or broken ladder.• Get help when carrying long or heavy ladders.• Be aware of surroundings when carrying ladders. Pay particular attention to
overhead obstacles and people around to avoid striking them.• Do not use ladders if you tire easily, are subject to fainting spells, are using medicine
or are physically limited.• You must be physically fit to work on a ladder.
• DO NOT USE A LADDER IF YOUHave a sore back, legs, arms, hands
Z Have dizziness, nausea, light headednessAre taking medications that affect your balance or concentration
• If you experienced a dizzy spell on a ladder:• Stop and drape arms over a rung• Wait until spell passes• Slowly and carefully descend ladder.
5) Storing and Transporting Ladders• Ladders should be supported to prevent sagging• Do not store items on top of ladders
• When carrying a ladder:V Hold middle side rail and tip front slightly upwardV Watch for swing in the tail endV Watch for overhead hazardsV Get help with long ladders (>1211) or in congested or public area where the
public may be injured

EXTENSION OR SINGLE-SECTION STRAIGHT LADDERS1) Ladder Selection
• Select a ladder of proper length to reach the working height and inspect prior to use.• Keep metal and wood ladders away from power lines and other live conductors• Use fiberglass ladders when performing work on or near electrical conductors
2) Set-Up
• Set ladder on firm ground. Do not use on ice, snow orslippery surface without non-skid devices or securing feet.
• Extend ladder 3ff above roof line and tie top at support points.V Extend top section only from ground, never by
“bouncing” or from the roof.- Secure the base when raising.• Never set-up ladder when it is extended• Position ladders at a safe angle. The recommended angle is
V 4:1 - Position the feet 1 foot back for each 4 feet up.• Do not overextend the ladder sections. Maintain
minimum overlap of sections• Have someone hold the bottom of the ladder when the top is not tied off• Securely engage ladder locks before climbing. Check to ensure the top and bottom
ends of ladder rails are firmly supported.• Protect the base of the ladder from any activity that could bang it (e.g. people,
doors, vehicles).• Have someone guard or block the area while work is being performed on the
ladder• Post warning signs or use pylons if necessary• Ladder MUST surpass upper level by 3 feet
4) Safe Climbing and Use
• Do not place in front of a door opening toward the ladder unless the doorway canbe secured.
• Face ladder when climbing up or down.• Do not overreach.• Keep body centered between side rails.• Move ladder as needed. Never “walk” a ladder while standing on it.• Maintain a firm grip. Use both hands when climbing.• Do not climb onto ladder from the side unless the ladder is secured against movement.• Do not stand on or above the 3rd rung from the top of the ladder. Never climb above
the top support point.• Do not use ladder in high winds.• Keep ladder close to work area. Avoid pushing or pulling off to side of ladder.• Do not place on boxes, unstable surfaces or on scaffolds to gain additional height.
