The most appropriate way of verifying electrical safety is to carry out a series of routine safety tests that
both reflect those tests used in the manufacturing process and, particularly in the hire industry, that take
into account the effects of normal wear and tear.

NSPECTION


It is important when carrying out routine testing to first check for signs of undue wear and tear by a
thorough visual inspection - a nick in the supply cable or a cracked casing etc can easily lead to hazardous
situations when the power tool or appliance is in use.

AFETY


The tests to verify satisfactory 'earth bonding' and insulation levels will depend on the basic construction of
the tool or appliance - Class I (Earthed) or Class II (Double insulated) - and the original standard to which it
was manufactured, the most common British Standards being BS2769 for hand held power tools, BS3456
for general appliances and BS415 for mains operated electronic, mainly audio/visual equipment.

However, clear guidance should be sought from the manufacturer, or importer, to determine the appropriate
requirement.
