1 KENORA CATHOLIC DISTRICT SCHOOL BOARD 600 Health and Safety Procedures AP 628: Portable Ladder Purpose Accidents involving ladders are common in the workplace because this tool is often abused and/or used improperly. A ladder must be used once you exceed a comfortable work height. The following section is intended to provide some guidelines and requirements for the safe use of portable ladders. Responsibilities Worker shall: Inspect all ladders prior to use Only use Canadian Safety Association(CSA) approved ladders Report, tag out and take out of service any defective ladders Comply with relevant legislation Supervisor shall: Ensure staff is properly trained in ladder use Ensure staff follow proper procedure as set out Take out of service any unsafe ladders Employer shall: Ensure all supervisors and staff are properly trained in the use of portable ladders Provide Personal Protective Equipment(PPE) as necessary to carry out work Adhere to ladder purchasing criteria Assign staff to carry out a thorough ladder inspection on an annual basis LADDER SAFETY PROCEDURES 1.0 INTRODUCTION Ladders are commonly used to reach or to gain access to higher areas/levels and sometimes from which to perform work. There are a number of hazards associated with ladder use that can cause accidents resulting in serious injuries. These potential injuries 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 ;

2 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 from which to work should be considered the least desirable method. Safer alternate methods such as performing work from stairs, scaffolding or elevating platforms should be considered first. This document describes different ladder types and outlines the procedures for proper selection and safe use of portable ladders. 2.0 TYPES OF LADDERS 2.1 LADDER TYPES Ladders may be fabricated from wood, aluminum or fiberglass and they come in different shapes and heights or lengths. Selecting the proper ladder depends on the particular task at hand. Ladder types include: straight extension sectional hooked trestle and extension trestle step platform (best choice if working from ladder) step For the purposes of the procedure only the straight, extension, and step ladders will be dealt with. The other ladder types may require different procedures and are for information only. KENORA CATHOLIC DISTRICT SCHOOL BOARD ADMINISTRATIVE PROCEDURE 2

Safer alternate methods such as performing work from stairs, scaffolding or elevating platforms should be considered first. When 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 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. This may be applicable. See chart (voltages and distance) Use fiberglass when working on or near electrical conductors Inspect Ladders Prior to Use Before using a ladder, be sure to inspect it to ensure it is in good working condition and safe to use. Inspect ladders for: Broken or missing rungs, cleats, safety feet or rails Slippery substances on rungs Stability Inspect for structural integrity Joints should be tight and secure Hardware and fittings should be secure, not damaged or corroded Moveable parts should operate freely Check side rails and rungs for signs of damage, cracks, fraying (fiberglass) Test rung locks (extension ladders) Check ropes, cables and pulleys Damaged or defective ladders must be immediately removed from service and not used.
