During air sealing and retrofit work ladders may be used to access attics, crawlspaces, ceilings, roofs and exterior walls. Choosing, inspecting, setting up, and working safely from ladders is essential as they are a frequent source of injuries in the work space. Ladders should be chosen by type of work and access requirements, and should always bear on stable ground in low hazard areas. Workers should always face the ladder and maintain three points of contact with the ladder while ascending and descending.
