This course is for security guards and other workers who use portable ladders now and then. It covers choosing the right ladder, inspection, the 4-to-1 rule, stepladders, three points of contact and when fall protection is needed. It is background knowledge only: your employer must train you on your site's ladders, and in Ontario, construction workers who use fall protection need approved working at heights training.

No. It is background knowledge only. Your employer must train you for the ladders and fall protection at your site, and in Ontario, construction workers who use fall protection must take working at heights training from a provider approved by the Chief Prevention Officer.
