Today's topic, you will identify the best practices for technicians and system engineers to consider inorder to prevent them from encountering unexpected electrocution or electrical hazards.The most prevalent physical hazards that computer technician and electrical engineers encounter mostly are electrical hazards.
Although it is necessary to run a computer, or any other device which may be sensitive.Electricity can damage sensitive computer equipment,other devices and in some cases, may pose a danger to humans.Observing or adhering to the best practices with regard to electrical safety will protect both devices and human lives.
For instances, Static Electricity is a build-up of stationary electrical charge on an object.it is called static because the charge attributed cannot escape the charged body.But rather remains still.
Static charges can be as very small as the sparks that come off a dry blanket in the winter time or as massive as a lightening strike, with its millions of Volts.
Static electricity is often caused by friction;rubbing one object against another causes a transfer of electrons between the two.And using friction to create a static charge is called Tribo-electric generation.The amount or Probability of static that can be built up in this manner depends on various factors.
including the types of materials,their surface area and texture, and the unprecedent ambient humidity.And because air has very high resistance static electric discharge usually requires contact with the statically changed object .
You can also feel a static discharge starting around 3,000V. The drier the air, the greater the resistance which is why static shocks on dry winter days can fall within the range of 10,000 to 20,000 Volts.If probably 120v from a household electrical outlet can kill you,why won't a static spark of 20,000V just startle you without a warning.
This is because, while the voltage might be high, the current is very Low: Very few total electrons are transferred in a static spark.And Keeping a room humidified is one way to reduce the risk of static electricity.Do not handle electrical equipment when your hands or feet are wet or when you are standing on a wet surface.
Remember that pesstimistic exposure to electricity may cause you fatal electrocution which can lead to serious injury or death. Adhere to every necessary safety precautions to ensure sanity.
