Falls from ladders are common to all trades and are one of the most serious safety problems in construction. Falls from ladders result in serious injuries and fatalities. There are four documents in this series – General, Types, Set up, and Inspection.
Ladders must be designed, constructed, and maintained so that no worker is placed in danger, and must be capable of withstanding all loads it may be used for. A portable latter at a project must be manufactured and meet the design, performance, test, and marking requirements of a Grade 1, Grade 1A or Grade 1AA ladder as specified in the CSA Standard Z11-12, Portable Ladders.
Any tools, ladders, scaffolding and other equipment or materials capable of conducting electricity must not be stored or used so close to energized electrical equipment, installation or conductors that they can make electrical contact.
When a fall protection system is to be utilized while using a ladder, Working at Height training must also be provided.
For more information about ladders, use the documents listed under the resources tab.
