Many companies provide ready-made stickers to indicate that a worker has been trained in electrical, confined space, or excavation trench safety, as well as operation of specialized equipment. Environmental monitors often make stickers to indicate that the worker has been educated on the risk of unexploded ordnance or the archaeological/biological sensitivity of a given area. Unions may offer hard hat stickers to their members to promote the union, encourage safety, and commemorate significant milestones.
