Any sort of work which includes an exposure to electrical circuits and equipment involves its own set of risks. Particularly, electricians are exposed to these hazards on a regular basis. We commonly know that electric shock is the only danger electricians are exposed to, but little do we know that electric arc explosion is an equally perilous threat, which can generate blistering heat called arc flash that can cause lethal injuries. read more
It’s not uncommon for home and business owners to contact an electrician when they are having electrical problems in their home. From electrical sockets causing shortages to replacing old light fixtures, there are a number of issues that people may need to be addressed.
Though each problem may be different, there are some common concerns that electricians and anyone who assists them must be familiar with and that is taking the appropriate safety measure to avoid unnecessary risks and injuries. That being said, here’s several safety precautions that must be taken to keep everyone safe. Read More
The answer must be “yes” .The centrifugal pumps in the pictures are all water pumps which exploded. The explosions did not occur because of any contamination or chemical reaction with something that was not supposed to be in the pump.
In fact, explosions like this have happened with very pure water – boiler feed water pumps, condensate pumps, and de-ionized water pumps. read more
Electrical shock is the major factor contribute to injury and more serious death statistic for electrical incident around the world.We can’t assume are is present or not because it is not visible and can look with naked eyes.
Electrical safety principle is to keep away person from live voltage.For electrical person,they need to clarify voltage value is safe or not before proceed any maintenance and repairing activity to avoid electrical shock using a multimeter.
To minimize the electrical shock incident,some country have the new standard and regulation for machine and power panel safety installation such as to install the Voltage Verification. read more
A new terminology for electrical currents now include all faults those between live conductors as well as earth or grounding faults.
If we not design our circuit protection properly followed standard guide,it can cause serious injury or death for human and equipment damage.
Fault current be determined at every relevant point. For small and medium installations with LV utility supplies, this is satisfied by determination of the fault currents at the incoming power supply. read more
As we known when working on electrical installations, safety matter is our priority.Every step we need to consider about hazards when perform electrical works.
Only competent electrician can work on electrical installation or live condition according to relevant industrial safety standards.Common industrial safety standard for electrical works such as VDE 0105 for Germany, and international standards for EN 50110 or IEC 60364.
For electrician,they need to special tools which have been tested and qualified with electrical standard.Hand tools also must suitable and followed the electrical standard IEC 60900 and it has specified worldwide requirements for tools for electrical live condition.
In the Electrical Engineering field,many cases of accident or death around the world causes by electric shocked.It very dangerous because we cannot see,smell and feel the electric current.
Current flow into our body and can make heart stop from functioning and can cause the serious injury even death.The level of danger for electric shock depends on the value of the body current and the time for which the current flows.
Human body have a different insulation value (Ohm) and also different current value can effected the heart.For the body have a low current level,it can easily attack the heart function and it so dangerous.
