This may be done using opening switches, removing fuses or links, opening circuit breakers or removing circuit connections. The risk of electric shock often results from people making contact with unprotected energised parts of electrical equipment and earth. The worker correctly observes the isolator is open, however they assume the earth switch can be closed because the isolator is open.

For example, if you engage an electrical contractor to nz out electrical work at your workplace you should consult with the contractor on how in general the work is to be carried out and in particular how risks to their health and safety and that of others at the workplace are to be managed while the work is carried out. The most effect control measure is to remove the hazard or hazardous work practice.

Work Health and Safety (Managing Electrical Risks in the Workplace) Code of Practice

The reason this Standard is used for test and tagging purposes is because it is recognised as credible document and is a reference document for many industries, organisations etc.

Electrical equipment commonly used 376 these types of lower-risk workplaces includes computers, photocopiers, stationery or fixed electrical equipment. Common examples of electrical equipment requiring an RCD include: A high voltage may develop across the open-circuited secondary winding causing an electric shock, arcing or a fault at a later stage. General Guidance — Use. Alternatively, it could be replaced or permanently removed from use.

If there are any exposed conductors in the immediate work area they should be separated by design or segregated and protected with insulated barricades, insulated shrouding or insulated material to prevent against inadvertent or direct contact. A record of testing must specify the following: Inspection and testing of electrical equipment may involve, in hzs For more information about the applicable electrical licensing or registration laws contact the local regulator in the relevant jurisdiction.

If Yesproceed to Part 2. Identifying and assessing the risks and developing risk control measures as described in the Code of Practice: Administrative controls involve the use of safe work practices to control the risk, for example the provision of suitable and adequate training, establishing exclusion zones, use of permits and warning signs.

The ways of controlling risks are ranked from the highest level of protection and reliability to the lowest. These persons will also have duties in relation to the health and safety of the electrical worker s and other persons at the place where the electrical work is being carried out. Insulated barriers should be of suitable material to effectively separate electrical workers from adjacent energised equipment. xs

What Is AS/NZS 3760?

Workers using hand-held or portable electrical equipment should be advised as to whether the outlets they use are adequately protected by RCDs. Working near sources of 33760, explosion or fires. All materials should be regarded as conductive unless proved otherwise.

For this purpose, you must consider all relevant matters, including the following: Isolation points should be fitted with control mechanisms that prevent the electrical equipment from being inadvertently re-energised.

They may also incorporate a risk assessment. For example, equipment may be at greater risk of damage if used outdoors or in a factory or workshop environment. Workers carrying out electrical testing must be appropriately trained and competent in test procedures and in the use of testing instruments and equipment, including: Can the work be undertaken while the electrical equipment is de-energised?

Consultation involves sharing of information, giving workers a reasonable opportunity to express views and taking those views into account before making decisions on health and safety matters. When electricity is restored tests must be carried out to confirm that polarity is correct, actives are switched and, where applicable, phase sequences are correct before electrical equipment is used.

The electrical equipment may also be fitted with a tag stating: If that is not reasonably practicable you must minimise the risk so far as is reasonably practicable. Residual current device RCD means nzx device intended to isolate supply to protected circuits, socket outlets or electrical equipment in the event of a current flow to earth that exceeds a predetermined value.

This can be a safe and ax alternative if the switchboard option is not reasonably practical. Type I RCDs are the most sensitive and are required for electrical equipment that is directly connected to people, for example patients in hospitals or dental practices. This is to prevent inadvertent use before the electrical equipment can be tested, repaired or replaced.

The RCD may be fixed or portable. A risk assessment can help determine: Risk assessment involves considering what could happen if someone is exposed to a hazard consequence and the likelihood of it happening.

Only competent electrical workers who have received appropriate training in high voltage electrical work are permitted to work on high-voltage electrical equipment. They provide multiple protected socket outlets and can provide RCD protection to multiple items of electrical equipment from one power board.

Test instruments that are to be used or connected to electrical equipment should meet the following conditions: This does not apply if the supply of electricity to the electrical equipment: For example, in an exposed energised high voltage situation, the electricity supply should be isolated and proved de-energised before carrying out a rescue.

Electrical work whether energised or de-energised must only be carried out by appropriately licensed or registered electrical workers. Do you have the appropriate insulating mats and sheeting? Contact with earth occurs through normal body contact with the ground or earthed metal parts. Fault finding should first be attempted in a de-energised environment using de-energised testing methods. This instrument commences on the day after it is registered on the Federal Register of Legislative Instruments.

The is a joint Australian and New Zealand Standard that describes the in-service safety inspection, testing method and frequency of electrical appliances.

This Code is divided into two parts dealing with: Proximity voltage testers should be tested for correct operations immediately before use and again immediately after use, particularly if the test result indicates zero voltage, to confirm that the instrument is still working correctly.

In nza heavy industries, cable protection ramps are used to protect cables.
