Morning folks
Is test and tag a legal requirement, no, it is a way to deemed safe (apart from two specific instances). What absolutely is a legal requirement (and our friends at WorkSafe don't appear to know this), the person responsible for an electrical installation is responsible for the safety of the installation and appliances connected to it under the Electrical (Safety) Regulations 2010
15 Using works, installations, fittings, appliances, and associated equipment
- (1)A person who owns or operates works, installations, fittings, or appliances must not use, and must not allow any other person to use, the works, installations, fittings, or appliances if the works, installations, fittings, or appliances are electrically unsafe.
Worksafe also appear not to have read the legislation that brought them into existence:
38 Duty of PCBU who manages or controls fixtures, fittings, or plant
at workplaces
(1) A PCBU who manages or controls fixtures, fittings, or plant at a
workplace must, so far as is reasonably practicable, ensure that the
fixtures, fittings, or plant are without risks to the health and safety of
any person.
So how do we not be reckless about the safety of appliances used in our workplaces? (applies to items used when working from home)
(1) Where possible we supply them through electrically safe RCD's which are regularly tested
(2) All appliances are tested and tagged by a suitably qualified/trained and experienced person
(3)Persons using appliances perform regular pre use checks (cord & plug, controls, guards present
and unmodified (90% of items fail a visual check)
So how do we reduce the cost of test & tag?
Don't accept the cheapest quote, the responsible person has to ensure that whoever is TnT'ing, knows what they are doing (most electricians/ESTs/EASs don't) Cheapest almost certainly won't detect all the issues.Leckies hate TnT, it's below their dignity and will slap five year tags on all office items, they also don't look at voltage and current ratings to determine what plug is required
Be aware that some TnT service providers will overtest things, by this I mean that things like Office Kitchen appliances should be TnT'ed yearly, likewise laptop chargers, heaters, extension leads, fans, power boards. Items such as monitors should only need to be tested on their introduction to service and then retested every 5 years, likewise terminals the IEC leads that supply them, printers and their IEC leads likewise.
In a factory/workshop six monthly retesting complies with Table 4 of AS/NZS760, being aware that an office in the middle of a factory gets items in it tested yearly/five yearly
Hire equipment every three months, with a visual check before each hire
Building site gear, you fellas/fellesses get to deemed safe by testing and tagging to AS/NZS3012 and Table 3 Periodic Verification specifies 3 monthly retests
For the last two, you cannot do a risk assessment and vary the retest interval (except to test more frequently)
When legally must an item be tested and tagged, if it is being sold secondhand, and if it is repaired and that repair could compromise it's electrical safety. So chuck something on TradeMe, must be TnT'ed first, send your drill into get a new chuck fitted, no, send the same drill in for a new cordset then yes
(Noting that second hand items get tested to AS/NZS 5761:2011 and repaired items to AS/NZS 5761
One thing you can do is to triage your appliances, as I said above 90% of fails will be visual, so before your TnT provider does his or her thing, do a walk round, remove disused IEC leads/power packs etc, check extension leads (after unplugging them) look for any sign of damage, if you have tools, are the guards present? (sparkies usually get this wrong too) Do switches and controls work? Rating plate present and readable (legal requirement).
