Skip to main content. Electrical Alert. Don't rush. Control hazards. Electricity has killed three people in the mining industry since August 7, An electrician contacted an energized component of a 4, VAC electrical circuit while adjusting the linkage between the disconnect lever and the internal components of the panel that supplied power to the plant feed belt motors.

A contract electrician contacted an energized VAC conductor while working inside a fire suppression system's electrical panel. An electrician contacted an exposed energized connector while troubleshooting a VAC flooded bed scrubber motor circuit on-board a continuous mining machine. Best Practices:. Never work alone. Talk to coworkers and confirm your plan is safe. Identify and control all hazardous energy sources before conducting any task and follow safe work procedures.

Electricians must know how to de-energize and disconnect electrical systems and equipment. Always troubleshoot without power first. If you must troubleshoot an energized circuit, use properly rated personal protective equipment to prevent hazards. For example, use electrically rated gloves, insulated blankets or mats, and polycarbonate barriers to prevent accidental contact with energized components.

We rely on electricity, but sometimes underestimate its capability of causing injury. Even household current volts can stop your heart. UW personnel need to be aware of the hazards electricity poses, such as shock, fire and explosion, and either eliminate or control those hazards. Electrical shock happens when current passes through the body. Electricity travels through closed circuits, and people, sometimes tragically, can become part of the circuit.

The major hazards associated with electricity are electrical shock and fire. Electrical shock occurs when the body becomes part of the electric circuit, either when an individual comes in contact with both wires of an electrical circuit, one wire of an energized circuit and the ground, or a metallic part that has become energized by contact with an electrical conductor. The severity and effects of an electrical shock depend on a number of factors, such as the pathway through the body, the amount of current, the length of time of the exposure, and whether the skin is wet or dry. Water is a great conductor of electricity, allowing current to flow more easily in wet conditions and through wet skin. The effect of the shock may range from a slight tingle to severe burns to cardiac arrest. Table

15 Safety Precautions When Working With Electricity

Beta This is a new way of showing guidance - your feedback will help us improve it. Electricity can kill or severely injure people and cause damage to property. However, you can take simple precautions when working with or near electricity and electrical equipment to significantly reduce the risk of injury to you, your workers and others around you. This section provides a summary of those precautions. Investigation showed that the 13A plug had been incorrectly refitted to the cabinet's main lead. This meant the metalwork of the cabinet, which should have been safe to touch, was dangerously live at mains voltage.

Safety must not be compromised and some ground rules need to be followed first. The basic guidelines regarding safe handling of electricity documented below will help you while working with electricity. Avoid water at all times when working with electricity.

Не останавливаясь, он отстегнул телефон от брючного ремня. - Говорите. - Где мой ключ? - прозвучал знакомый голос. - Кто со мной говорит? - крикнул Стратмор, стараясь перекрыть шум. - Нуматака! - огрызнулся сердитый голос.  - Вы обещали мне ключ.

ТРАНСТЕКСТ не может с ним справиться. Сьюзан подумала о Стратморе, о том, как мужественно он переносит тяжесть этого испытания, делая все необходимое, сохраняя спокойствие во время крушения. Иногда она видела в нем что-то от Дэвида. У них было много общего: настойчивость, увлеченность своим делом, ум. Иногда ей казалось, что Стратмор без нее пропадет; ее любовь к криптографии помогала коммандеру отвлечься от завихрений политики, напоминая о молодости, отданной взламыванию шифров. Но и она тоже многим была обязана Стратмору: он стал ее защитником в мире рвущихся к власти мужчин, помогал ей делать карьеру, оберегал ее и, как сам часто шутил, делал ее сны явью. Хотя и ненамеренно, именно Стратмор привел Дэвида Беккера в АНБ в тот памятный день, позвонив ему по телефону.

 - Она направилась к двери. - Ты уходишь. - Ты же знаешь, что я бы осталась, - сказала она, задержавшись в дверях, - но у меня все же есть кое-какая гордость. Я просто не желаю играть вторую скрипку - тем более по отношению к подростку. - Моя жена вовсе не подросток, - возмутился Бринкерхофф.  - Она просто так себя ведет. Мидж посмотрела на него с удивлением.

Сьюзан пожала плечами. - Обычная проверка кандидата. - Ну и ну… - Беккер с трудом сдержал улыбку.  - И что же ты ответила. Она ткнула его в ногу носком туфли.

На ВР последняя стена стала уже тоньше яичной скорлупы. Джабба поднял брови. - Хорошо, это ничего не дает.

Беккер кивнул: - Самым решительным образом. Консульство этого так не оставит. - Надеюсь. - Месье Клушар.  - Беккер улыбнулся и достал из кармана пиджака ручку.
