You may be exposed quite frequently to mechanical risk factors at your work as a municipal cleaner due to characteristics of your work: using equipment with moving parts (e.g. chainsaws), risk of injury from items moving out of control (e.g. pieces of woods or stones being catapulted by equipment, or objects that may fall from buildings or vehicles passing by), working on mixed surfaces (e.g. uneven, or slippery), being exposed to sharp objects (e.g. broken glass, sharp sheets or shards of metal), performing work in proximity of road traffic (producing risk of being hit by vehicle passing by).
