Electrical safety is an essential factor for consideration at all facilities and products that uses electricity. It is a must consider before, during and after any electrical installation, design, production, maintenance, and troubleshooting. As a good servant , it gives power to nearly every appliance we use on daily basis but when disobeyed, it becomes a very bad master.
There were reports of electrically motivated fatal issues such as electric shock, fire, burn, electrocution and even death. It’s our responsibility as users and handlers to consider safety as primary issues. It is the duty of all of us to learn safety precautions and comply with professional ethics, government regulations and standards regarding use of electricity for equipment and installation of buildingCommon Electric Mistakes to avoid:
- Dependent on use of extension boxes and overloading electrical circuits;
- Knowing little about your device;
- Leaving broken chords unattended;
- Lack of preventive maintenance on equipment and installations;
- Excessive current leakages – regularly check for safety by confirming electrical leakage current is withing acceptable limits;
- Wet environment;
- Failure to report electrical faults;
- Handling repairs by unskilled or inexperienced personnel.
Manufacturers are duty bound to protect equipment by following standard design and manufacturing guides, and also electrical installation of building should follow guiding rules and adequate protective gears put in place.
A variety of electrical devices are available to protect against those aforementioned disasters and they include common fuse, and circuit breakers. There are different types of fuses and circuit breakers. we have normal, slow blow and fast blow fuse. Circuit breaker include the following: Air Circuit Breaker (ACB), Modulated Case Circuit Breaker (MCCB), Miniature Circuit breaker (MCB), some circuit breaker used in high voltage include Vacuum Circuit Breaker, Oil Circuit Breaker, Earth Leakage Circuit Breaker, Ground Fault Circuit Breaker (GFCI), and Residual Current Devices (RCD).
These are essentials questions for the asking- What needs to be protected? When and by Whom? And What are the essentials for electrical protection?
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.
