AS 5230:2021 pdf free.Safety of machinery一Electrical equipment of machines Part 32: Requirements for hoisting machines (IEC 60204-32:2008 (ED.2.0) MOD).
4 General requirements
4.1 General considerations
This standard is intended to apply to electrical equipment used with a wide variety of hoisting machines and with a group of hoisting machines working together in a coordinated manner.
The risks associated with the hazards relevant to the electrical equipment shall be assessed as part of the overall requirements for risk assessment of the hoisting machine. This will determine the acceptable level of risk, and the necessary protective measures for persons who can be exposed to those hazards, while still maintaining an acceptable level of performance of the hoisting machine and its equipment.
Hazardous situations can result from, but are not limited to. the following causes:
— failures or faults in the electrical equipment resulting in the possibility of electric shock or fire of electrical origin;
— failures or faults in control circuits (or components and devices associated with those circuits) resulting in the malfunctioning of the hoisting machine;
— disturbances or disruptions in power sources as well as failures or faults in the power circuits resulting in the malfunctioning of the hoisting machine;
— loss of continuity of circuits that depend upon sliding or rolling contacts, resulting in a failure of a safety function;
— electrical disturbances, for example, electromagnetic, electrostatic either from outside the electrical equipment or internally generated, resulting in the malfunctioning of the hoisting machine;
— release of stored energy (either electrical or mechanical) resulting in, for example, electric shock, unexpected movement that can cause injury;
— surface temperatures that can cause injury.
In accordance with the hierarchy of protective measures described in ISO 12100-1 and ISO 12100-2, the required risk reduction is achieved by measures implemented by the supplier at the design stage and further measures implemented by the user.
The design and development process shall identify hazards and the risks arising from them. For those hazards that cannot be removed and/or those risks that cannot be sufficiently reduced by inherently safe design measures, other protective measures such as safeguarding shall be provided to reduce the risk. Additional means (for example, means such as flashing beacons, warning notices or signs to raise awareness of the risks) shall be provided where further risk reduction is necessary. In addition, working procedures that reduce risk may be necessary.AS 5230 pdf download.
