Lesson 6 Mechanical factors

  • Workers may be exposed to a large and mixed group of factors that are quite specific.
  • Those are called “mechanical factors”, which are factors of physical nature, able to cause injuries or even death.
  • Mechanical hazards arise from interaction between parts of human body and items from the working environment: tools, machines, equipment, materials used in production process, etc.
  • Moving machines and items being transported
  • Elements moving in controlled manner
  • Elements moving in uncontrolled manner
  • Sharp, protruding elements
  • Falling elements
  • Pressurized liquids
  • Slippery, uneven surfaces
  • Limited spaces (e.g. corridors, entrances, etc.)
  • Location of workplace in relation to ground level (e.g. work at heights or in pits)
  • Other, like e.g. live animals
  • Cutting
  • Crushing
  • Shearing
  • Stabbing
  • Puncture
  • Entanglement
  • Drawing-in
  • Trapping
  • Driving into
  • Driving over
  • Slipping
  • Falling, etc.
  • You may be exposed quite frequently to mechanical risk factors at your work and a municipal cleaner due to characteristics of your work and 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).
