Electricity is widely embraced in every aspects of life today as it is almost if not impossible to find equipment not using electricity one way or the other though it is possible to find manual copy of some portable equipment especially find in the home for some light duties. Even though many people don’t know what it entails to produce this resource and its associated features, no doubt it is a significant part of life which we may not find a matching substitute.
Therefore it is a matter of necessity for you first as users, then as a Technician or Engineer, or whatever category to know how to handle this resource with respect in any area you may find it. Electricity is a very obedient servant when you respect it but it may become nasty if you disobey proper handling principles. I am not trying to scare you. Why would I do that? I have handled electricity as a kid now I am an adult and I am still handling it so fear not. You just need to get the information I am trying to share with you as a user or expert.
Let me assure you it is fun using, producing and working on electrical devices. The reason some stop pursuing courses related to electricity is fear but they still use it so why fear? If you are really interested in related career and not because they ask you or push you to it, then I assure you will find it interesting, funny, rewarding and fulfilling.
Lessons in Electrical Safety is a prerequisite for anyone willing to work in any laboratory, workshop, and anywhere you will handle electrical apparatus and most especially to a student of electricity and electronics. No one has seen electricity but we see its effects in what it does like light, sound, motion, heating, if you don’t know, your body as human and body of animals generates electricity. Have you heard of electric eel?
There exist two types of electricity static and moving/current electricity which may divide into Direct Current (DC) and Alternating Current (AC). A unit of electricity is Voltage or V so you see them write direct current or alternating current voltage. Anything which allows electric current to pass through it unhindered is a conductor while its opposite insulator would not allow electric current to pass at all, but there is an in between materials called semiconductor. These materials will either allow passage of electricity or not depending on certain conditions. Therefore to prevent danger inherent in electricity, use materials that does not permit electric current to flow, an insulator. Electric cable consists of conductor and insulator, the inner material is a metal conductor while the outer is rubber or another type of insulator. It is important to know some materials such as water and methylated spirit like other fluids are not truly conductors but they assists in smooth flow of electricity by offering some resistance when impurities is in them.
It is the responsibility of an on duty Technician to ensure safe use of electrical equipment at his or her care before handling over to users department and to ensure safe handling of that equipment by the user in a safe condition and environment. It is also pertinent for the technician to ensure the equipment is safe for handling at all time especially when using in wet areas is inevitable. Electrical Safety Test is a must to carry out on regular basis especially when you have just install or repaired the equipment. You may want to know more about electrical safety for technician and users especially in offices, home and hospital environment then check it out soonest.
