People operating machinery and equipment could: • be required to place their hands close to the mechanism of the machinery and equipment that does the work, and may be injured if caught or trapped by moving parts • be exposed to constant harmful noise, radiated energy or fumes being emitted

Equipment has a wider definition, which basically refers to things needed for a certain task. They act as a set of facilities used in the mechanical works or any other works. The equipment can also be said to be a set of tools used by a human being for a

People providing cleaning services could: • work alone • access machinery and equipment from the rear or sides, or in unexpected ways • climb on machinery and equipment • enter confined spaces, or larger machinery and equipment • become trapped by the mechanism of the machinery and equipment through poor

Machines are used broadly in the field of mechanics. The word mechanical refers to the work that has been produced by machines or the machinery. It mostly relates to the machinery tools and the mechanical applications of science.

The two buttons must be pushed at the same time and are located at a distance from each other that prevents simultaneous operation by one hand. The operation should be designed so that if either or both of the buttons are released, the hazardous action of the machinery and/or equipment

Where exposure to machinery and equipment hazards cannot be eliminated or substituted for machinery and equipment of improved design, risk controls must be applied to the hazards to prevent or reduce the risk (chance) of injury or harm.

People performing these tasks must be provided with the means to get themselves and any equipment they require onto the roof with no risk, or minimal risk of fall or injury.

Note: Safe work practices must take into account the risk of trapping an operator between the EWP and a fixed structure (e.g. overhead beams, electrical cables, pipes).

• Separating people from non-mechanical hazards is necessary where the emission cannot be controlled at the source through elimination or substitution. Hazardous machinery and equipment emission controls rely largely on isolating of people from the hazardous emission. Hoods, lids, covers or impervious guards (solid barriers that prevent escape of the

Accidental start-up, or movement of a machine mechanism, can occur: • if control levers or buttons are bumped or knocked • if a short circuit of the control system occurs • when hydraulic or air pressure is released • when undoing retaining bolts. The word machine is derived from the

A critical safety system is a safety control system responsible for ensuring the safety of a person when approaching or accessing a hazard. Failure of the critical safety system will leave a person exposed to the hazard, and in danger. Critical safety systems may include barriers or guards fitted to

Working at height. Providing people with a suitable work platform for the task being undertaken reduces the risk of injury from falling from machinery and equipment. Often safe access equipment, made available during installation of machinery and/or equipment, is removed after commissioning.
