Testing and tagging
Employers and other PCBUs must make sure electrical equipment is regularly inspected and tested by a competent person if the electrical equipment is:
-
supplied with electricity through an electrical socket outlet ('plug in' equipment), and
-
used in an environment in which its normal use exposes the equipment to operating conditions that are likely to result in damage to the equipment or a reduction in its expected life span, e.g. conditions such as exposure to moisture, heat, vibration, mechanical damage, corrosive chemicals or dust.
Mobile phone chargers and ‘similar hand-held electronic devices’ that are connected to an electrical supply could potentially become damaged and this could create a risk of electric shock or, worst-case scenario, electrocution.
However, if the phone charger is not used in conditions likely to result in damage to the charger or a reduction in its expected life span, testing and tagging are probably not required for the charger.
