-- proliferation of electrical and electronic devices in the home, leading to a
surprising and shocking bill at the end of the month;
-- excessive current flowing in an inadequately sized conductor, leading to
overheating and possible fire;
-- grave mortal danger to a human person, caused by placing his body in-circuit
between the mains supply and a grounded point.
Note that none of these risks is "caused by" the mains voltage. Any risk is due
to careless and inattentive handling of the mains supply by people responsible
for its proper use. In this respect, mains voltage is no more risky than a car,
a bottle of sleep aid tablets, a pistol, or a discarded banana peel.

How do you run induction motor above rated speed?
From the ordinary A.C. mains - you can't.The induction motor tries to run at a speed determined by the AC mains frequency supplied to it - in the U.S. it's trying to run at some fraction of 3600 r.pm., here in Australia, it's some fraction of 3000 r.p.m.The problem is that the motor relies on the stationary winding (stator)'s magnetic field inducing an opposing magnetic field in the rotating rotor. This can only happen if there is a slight speed difference between the two magnetic fields - this is "slip".Slip increases with increasing load - the motor slows when you load it.High-tech motor controllers create a variable-frequencysupply. Such controllers can output an AC supply at a higher frequency than the mains, so it's possible to make the motor run above its "nameplate" speed.This is not usually done - the rotor is designed for a maximum r.p.m., higher r.p.m.s pose the risk of destroying the rotor due to excessive "centrifugal" forces.
What is the purpose of using 3 different colour wires in an electric iron?
The live (blue) wire delivers the power from the mains into the iron's circuit. The neutral (brown) is the return path back to the mains (electricity needs a closed circuit to flow). The earth (green/yellow stripe) wire is a safety device in case anything goes wrong with the wiring in the iron to cause a short circuit. It delivers the power along the earth wire into the ground instead of it going through the user.The Iron would work without the earth wire being connected but the user would be at risk of electric shock if the iron developed a fault or the wires came loose.
What problems can occur with the hand fitting activities and how can these be overcome?
You could cut yourself or otherwise injure yourself. These are hard to overcome within the activity itself, but it's possible to reduce the risk of injury with more caution.
Why do light industry and heavy industry use different voltage?
Heavy industry and light industry use different voltages because usually the heavy industry has larger and more powerful machines, therefore the voltage needs to be higher. On the other hand, if high voltage is used in Light industry, with smaller less powerful machines, it could be very dangerous with risk of fire and harm or death to workers and staff.
Should i wear a grounding strap when servicing a CRT monitor?
I would suggest not wearing one, because the CRT uses very high voltages which could potentially remain while you are servicing it. Grounding yourself will put you at a greater risk of serious shock. The parts in a CRT are generally not as likely to be static sensitive as many other electronic devices, so the need for a grounding strap is not as great. Also, before working with a CRT, do some research into other precautions you should take to avoid electric shock.

What is financial risk management?
Financial Risk Management is a process of evaluating and managing current and possible financial risk at a firm as a method of decreasing the firm's exposure to the risk. Financial risk managers must identify the risk, evaluate all possible remedies, and then implement the steps necessary to alleviate the risk. These risks are typically remedied by using certain financial instruments as a method of counteracting possible ramifications. Financial risk management cannot prevent a firm from all possible risks because some are unexpected and cannot be addressed quickly enough.

Risk management deals with a variety risk deals with mitigating companies possible risk losses and compliance in the work place.
