30) Recognise the distinct hazards and risks of working on or near to HV equipment and systems (Knowledge, basic level)

31) Discuss appropriate control measures for working on or near to HV equipment and systems (Knowledge, intermediate level)

32) Explain arc flash hazards, risks and appropriate protection measures including Arc Flash Risk Assessment (Knowledge, intermediate level)

33) Recognise the varied sources of hazards from HV equipment: electrical, mechanical and pressure stored energies, gasses, chemicals, thermal energy, radiation, inductance (Knowledge, basic level)

The instructor shall:

Lead a discussion to explain and illustrate hazards, risks and controls of working with HV equipment using real world examples:

a. hazards, such as electricity, heat, chemical hazards including gasses

b. risks, such as electrocution, arc eye, burns, asphyxiation, fire, flashover, explosions

c. stored mechanical and pressure energies within switchgear, or other HV equipment

d.

thermal energy - radiation and inductance

e. hazardous insulating media and chemical hazards from SF6, non-greenhouse gasses or other insulating gasses and oils

Explain Arc Flash Hazards and protection, including the requirements for

a.

Arc Flash Risk Assessment

b. Difference of mandatory requirements for some regions such as under NFPA 70E or others

The participants shall:

Engage in group discussion on hazards, risks and controls of working adjacent to or on HV equipment based on the examples from the instructor
