Rust develops easily if the walking equipment is being taken into the toilets or is being used while bathing. Rust reduces the strength of the equipment significantly and it makes it difficult to assess actual damage to the metal. This is especially important for weight bearing parts.

These checks are especially important while taking walking equipment on rent which would have been used earlier. Look for newer, non rusted equipment when renting walking equipment. Old rusted equipment might come cheap but it may not be worth the risk taken
