Describe proper clothing when electric work is conducted. 6. Degrees of burns with electric power and the injuries. 7. What did you learn regarding safety at work, in the lab and protecting you and your co-workers? (Most important part). The following is taking notes from the video. Electric Safety – Fuses Part One – Arc and Blast – Misapplication of Low Voltage Overcurrent Protective Devices – The 600-volt one time fuses w the 10000 amp interrupting rating will be subjected to a cord of 100000 amp (which is far of its success of an interrupting rating) – The fault is again initiated by the closing switch ny the testbox and can hear/see the rupturing of the fuse as they tremendously short circuit energy and forces one of fuses out of its clip – 100000 amp with 480 volts (serious misapplication) – The tenth brought closing switch initiates the box and observe the results = an explosion and a hazard, misapplied Common Hazards in Electrical Systems – Low and Medium Voltage Arc and Blast – Polyester in flammable The Medical Facts of Electrical Burns – Burns give us tissue destruction such as thermal, electrical, and chemical radiation – Not only skin but all parts of the body. Including nerves, muscles, blood vessels heart and bone – On the job, you have a special exposure to thermal and electrical burns – Thermal burns = injury is outside and in. the outer layer is injured – Electrical burn = goes to structure inside. Nerves, muscles, and blood vessels. When vessel is destroyed, all the tissue houses are destroyed. Therefore, blood vessels are destroyed because they contain sol solution. – Electrical burn is from inside and out. – Most are third degree – Best way to treat a burn is to avoid and follow safety regulations – Electrical burn can affect you heart = try being calm and avoid extortion Arc Flash – The box where the guy was blown up – An electrical burn – should remain calm but also help the guy that had gotten injured – Seek help immediately
