Turn off switches before working on electrical gadgets

You might be pretty much conversant with the operations of domestic electronic appliances, but that does not make working on live wires advisable. If you feel you need to take a look at any particular functional part of your television, mixer, fan, or any other electronic gadget, make it a point to switch off the concerned equipment first. The same should remain a priority, even when you avail the services of a professional contractor.
