aside from OSHA and other regulations?
there is a great risk of death from electrocution while working with circuits.
your body is largely made of elements that will allow a current to flow thru, if you happen to touch a live circuit the electricity will assume the path of least resistance to the ground. This will leave the body badly burned if not completely dead.
Electrical equipment shall be so positioned that it 1) it does not impair the function or safety of other equipment, 2)it is readily accessible for installation, 3)replacement, 4)operation, 5) testing, 6) inspection, 7) maintenance and 8) repairs. 9) all parts of the installation shall be accessible without the need to enter any adjoining premises.
Because laboratory equipment must be very clean.
PAT or Portable Appliance Testing is the process by which industrial electrical equipment is inspected and tested on site at regular intervals to ensure worker safety. The testing procedure involves resistance testing, polarity checks and checking safety switch functions. Equipment that passes PAT is certified "safe" and labeled as such. Although the term PAT applies to the process in the UK, Australia and New Zealand., All industrial nations have similar processes required by workers' compensation organizations, government regulations and insurance companies.
If you are asking this question, then it is not safe for you to work on ANY electrical lines... But, to answer your question, a tag does not mean the line is "de-energized". ALWAYS check lines with the appropriate testing equipment (volt meter, etc) and never rely on a tag before working on any electrical lines. I can only hope this question was a joke.
A portable appliance tester is a device used to check the safety and electrical integrity of electrical appliances. It typically performs tests such as insulation resistance, earth continuity, and polarity checks. This helps ensure that appliances are safe to use and comply with electrical safety regulations.
Electrical shock, electricity discharge and short circuiting, these can all be minimised by simply turning off the power
For measuring electrical Current the electrical equipment used is Amphere meter. This equipment tells the current flow in the equipment.
Portable appliance testing (PAT) is basically a method of testing (using a device and by sight) that any electrical equipment, cables, devices, machinery is safe to use.
The hazard is electric shock, flasover, short circuit, fatality. Care should taken to use right tool for roght application. The tool must sutably insulted. The person using the tool must be qualified and trained to do the said job.
In equipment engineering, its meager test is electrical insulation test. Its testing the grounding of an equipment.
Pat testing equipment allows you to test your electrical equipment to make sure that it is safe to use. It stands for Portable appliance testing which basically means it allows you to test portable appliances.
Once could find good deals on electrical testing equipment at any electronics store. These could be found at Walmart, Best Buy, Radio Shack, Amazon, and Ebay.
Test and inspection of electrical equipment should always be carried out when commissioning . This will done before voltage is applied , usually known as dead testing to verify the suitability . Live testing will then be carried out to confirm compliance with regulations .
A multimeter - is a piece of testing equipment used in electronics and electrical diagnostics.
Hazards associated with assembling and testing electronic circuits include slashed chemicals, and toxic fumes. These hazards can be minimized by proper ventilation, and wearing protective gear.
