Machine-Mounted Tool Hazards

Falling debris is of particular concern in demolition projects, both in terms of the workers actually doing the demolition work, and other workers or bystanders. Make sure the demolition area is clear of all unnecessary personnel prior to work. Large attachments, such as those on excavators, require a viewing area of at least 75 feet, and one of about 30 feet for smaller attachments, such as those mounted on skid-steer loaders, backhoe loaders and mini-excavators. Make sure all attachments are installed according to the manufacturer's guidelines. Refrain from modifying tools or equipment without first contacting the manufacturer.

When an excavator, skid-steer loader, or other piece of equipment is used on a floor deck, floor openings must have protective curbs installed to prevent the equipment from falling through the opening.

Excavators should have cab safety screens installed over top and front glass when demolishing any type of overhead structure, as well as a falling objects protection structure (FOPS). Cab windows should be of transparent, shatterproof glass.

The ball on a ball and crane should not exceed the smaller of 50% of the crane's rated load capacity, or 25% of the breaking strength of the wire rope on which the ball is suspended. Check with the crane manufacturer before beginning work to determine if the crane can be used safely for demolition, as a demolition ball places unusual stresses on a crane boom.
