Ladder slips account for more than one third of all ladder-related fall
incidents. The US-American National Institute for Occupational Safety and
Health (NIOSH) is collaborating with SRI International, an independent
nonprofit research and development institute, to develop a prototype device
that will enhance extension ladder stability. The device will use an innovative
electroadhesion technology invented and developed at SRI. Electroadhesion
provides a means to electrically attach a ladder to a variety of building
surfaces using considerable force, thereby providing increased traction and
resistance to slip. Applying electroadhesion technology to ladders has the
potential to improve their stability on variety of materials with smooth,
rough, and dusty surfaces.
