3. Non mechanical hazards
Definitions For the purpose of this presentation a machine or a mechanical device is considered to be a device that performs one or more functions, e.g. cuts wood; moulds plastics; carries product on a conveyor, etc. When used in the workplace such machines become work equipment.
Definitions When we consider mechanical hazards
we are concerned with the hazards posed by
the moving parts of a machine / work equipment.
For the purpose of this presentation mechanical
hazards are defined as those hazards that are
associated with the moving parts of a machine.

Recognising Mechanical Hazards If a machine looks dangerous then it probably is………..
Recognising Mechanical Hazards Can I come into contact with a moving part?
Can I become entangled in a moving part?
Can I become trapped between moving parts?
Can I be struck by a part or product of the machine?
Recognising Mechanical Hazards In Running Nips
These are usually associated with belt drives, chain drives, rolling drums and conveyor systems.
A worker using this machine became entangled in the protruding bolts and was dragged into and then thrown over the machine resulting in his left forearm being ripped off at the elbow.

Mechanical Hazard Fatality
A worker died when he became entangled between the cylinder and the feed on this machine. ‘X’ marks the spot where he was standing when he was pulled into the machine.
Non Mechanical Hazards
Non Mechanical Hazard!
Source! Consequences!
Hot and cold parts! Engines, freezers, boiler plant, furnaces!
Burns, frost bite, heat stress, heat stroke!
Electrical parts !
Generators, electrical motors, all electrically operated plant!
