ELECTRICAL HAZARDS CHECKLIST QUESTION

CHECKLIST

1. Are switchboards properly constructed and set up?

Ensure supply switchboards are of robust design and build.

2. Are all circuits, portable equipment, electrical plant and tools protected from earth leakage?

Check that every final sub circuit, all portable electrical equipment, electrical plant and tools are protected.

3. Are the correct general purpose outlets being used?

Check that general-purpose outlets with double pole switches are used for 240-volt sockets on portable equipment.

4. Are the portable outlet devices suitable?

Double adapters are not suitable for normal use on construction sites. Check that multiplug portable outlet devices comply with SANS 10142-1:2001.

5. Are electrical powered tools and flexible leads in a safe condition?

Ensure that all electrical powered tools and leads are safe is by having them inspected, tested and tagged by an electrician when they are first brought on site and then at regular intervals. Keep a site of inspections. Make sure unserviceable tools or leads are immediately withdrawn from service until they are repaired or replaced.

COMMENT

They should have: 1. A tie bar to prevent strain at termination of cables / wiring 2. Insulted stands for the of cables and extension leads 3. A lockable door to prevent damage to leads 4. A method of ensuring the door is kept open when undertaking electrical installation work 5. Weatherproofing when located outdoors and anywhere subject to water 6. A clear area of 1m at the front 7.

ELECTRICAL HAZARDS CHECKLIST CHECKLIST QUESTION 6. Have Electrical Certificates of Compliance been issued? 7. Have earth leakages been tested? 8. Are portable generators suitable?

COMMENT Ensure that Electrical Certificates of Compliance have been issued for all construction wiring, including switchboards, before use Ensure that earth leakages are tested by operation of the test button before each use, and tested for tripping current and time by an electrician every calendar month while used on site. Check that portable generators are: • Fully serviceable and properly maintained • Fitted with a 30 mA earth leakage • Installed by a ed electrical contractor (Where supplying a fixed installation) and an Electrical Certificate of Compliance is provided and, before use, generators are inspected by an Electrician. • Provided with earth and bonding connections according to the manufacturer / supplier information displayed on the generator.

9. Are leads set out safely?

Check that leads are not lying in mud, water or in areas where they can be damaged or become tripping hazards. Use stable, insulated lead stands to keep them above headheight. Do not allow leads to be wrapped around scaffolds or formwork – use S shaped off-cuts of steel reinforcing bar sheathed in cut-off lengths of garden hose instead.

10. Are plant and temporary structures a safe distance from power lines?

Make sure there is always a safe distance between live power lines and cranes, earth moving equipment, elevated work platforms, hoists, scaffolds, formwork and portable ladders by observing “no go zone” safe clearances.

11. Is electrical installation and repair work undertaken safely?

Make sure that all electrical installation and repair work is supervised by licensed electricians.
