Portable Ladders

Feet and Levelers

Check the area of the ladder where it sets down on the supporting surface. Check the feet for any missing or bent traction devices. Check that rivets are tight and the connection does not move at the attachment point unless it is designed to do so.

Examine factory attachments to be sure they are in place and functioning properly. Bent or “sprung” ladders should be taken out of service.

Visible Rating

Ladders must be marked with ladder size, type, maximum length, number of sections (if appropriate), highest standing level, total length of sections (if applicable), model number, manufacturer’s name, manufacturer’s location, and date of manufacture. Usage guidelines and other warning statements must also be placed on the ladders in specific locations depending on ladder type. Ladders appropriate for electrical work should be available and clearly identified. Check that ladders are available which are appropriate for the rig workers at that site.
