00:06introduction to portable appliance testing what is a portable electrical appliance according to
00:13the health and safety executive hse a portable electric appliance pat is any item that can be
00:21moved either connected or disconnected from an electrical supply almost all portable that is
00:27movable appliances have a cable or lead and a plug portable and movable equipment includes the
00:34following electrical equipment which is relatively easy to move around such as kettles vacuum cleaners
00:41floor polishers portable heaters electric fans lamps radios microwave ovens small electric cookers
00:50laptops computer and film projectors onions hair dryers food mixers and toasters larger items such
00:58as water coolers fridges photocopiers and fax machines vending machines washing machines and dryers electric
01:06cookers and computers handheld items that do not have a plug but are fixed or wired in are considered to
01:14be
01:14portable appliances a good example can be the hair dryer however larger electrical items such as wired
01:21in boilers and heaters are not battery charging equipment that is plugged into the mains such as
01:27mobile phone chargers are included but not the phones themselves extension leads to multiple adapters and
01:35collection lead what are the risks the main hazards of working with electricity are electric shock
01:44burns from human contact with live parts injury from exposure to arcing fire from fog electrical
01:51equipment or installations explosions caused by poly maintained electrical apparatus or static electricity
01:58igniting flannable materials paper or dust electric shocks can also cause other types of injury such as
02:06when a person falls from a ladder or scaffolding risk can also come from obstructive or poorly laid out leads
02:13cables cables and wires rodents tend to be considered as part of general workplace health and safety
02:19rather than specifically electrical problems however always report cables and wires that appear to be in
02:26hazardous or risky position understanding shock risk all who are involved with electrical systems are termed
02:34duty holders by the law a good understanding of the dangers and effects of electric shock is necessary for
02:40those employees and workers who only have limited knowledge of electricity but are still charged with their
02:46company's appliance testing it will help give meaning and confidence to the inspection and that process
02:53electric shock electric shock is the term used to describe the passage of electric current through the
03:00body in such magnitude as to have harmful effects which can be extremely damaging and life-threatening
03:06the effects of current passing through the human body which originated from different amplitudes can be
03:12summarized as follows ma equals milli amperes or milliamps 1 to 2 milli amperes barely perceptible 5 to 10
03:21milli amperes the subjected individual will be thrown away from the appliance and will experience pain 10 to 15
03:28milli amperes the person will experience muscular contraction and won't be able to let go of the equipment
03:3520 to 30 milli amperes breathing is impaired more than 50 milli amperes may experience a heart attack
03:43and death a little about risk assessment the control of risk arising from the use of portable electrical
03:50equipment should be based on a risk assessment a risk assessment identifies hazards and institutes
03:56appropriate mitigation and measures to control risk in the workplace often partly by setting up an
04:02appropriate maintenance plan there will be no wrong risk assessment later in the course legislation
04:10while there is currently no absolute legal requirement for pat testing the government has produced
04:15regulations which govern the maintenance of electrical appliances the most effective way for employers to
04:22conform to these regulations is by pat testing the hse expects you to perform pat testing to ensure that
04:29you are compliant with the appropriate regulations insurance companies also expect compliance to validate their
04:35policies fully several published regulations that have been implemented are the health and safety at work act
04:431974 hswa the management of the health and safety at work act regulations 1999 the provision and use of work
04:53equipment regulations 1998 the electricity at work regulations 1989 ewr
