Things to check before use Folding Ladder

All joints must be checked if they are all in definitely good condition.

The lock must be strong enough to bear the pressure weight when totally spreaded.

Is the surface of the steps and the body of the stairs clean and tidy? The ladder used by technician may be stained with lubricants, grease or oil. Thus, it must be cleaned thoroughly before using it again.

The working area must be consistent with the adjustment of the level. The height is considered as a whole, the ladder itself. Then you should consider the obstacles and the risk of crashes below especially when working at roadside. Wire and others must be in details before start working.
