The American Ladder Institute (ALI) has a lot of free resources about basic ladder safety and training information. You can learn about how to select the right ladder for the job, as well as how to identify the different varieties.
This website also includes 4 ladder safety training videos: Mobile Ladder Safety, Articulated Ladder Safety, Single and Extension Ladder Safety, and Stepladder Safety.
You can also find a Ladder Safety Checklist, which can be downloaded and used as part of safety training and a daily reminder.
Cal/OSHA has a portable ladder safety etool which has a useful section on Inspection, Use, and Maintenance. This etool also summarizes the California regulations pertaining to ladder use.
In addition to these free resources, the Loss Prevention Department is here to help with any questions or assistance you may need.
