It is more likely that this will happen during electrical testing and fault finding, when conductors at dangerous voltages are often exposed. You can minimise this risk if testing is done while the equipment is isolated from any dangerous source of supply, although this is not always possible. Take care to prevent contact with any hazardous internally produced voltages. The most serious injuries are caused by electric shock. The effects of a shock are largely unpredictable and can easily lead to a fatal injury. However, there is also a risk of burn injuries from arcing when conductors are accidentally short-circuited.

| Hazard Category | Hazards | Controls |
| Electrical Testing | 1. Can occur through contact with live conductors. | 1. Work shall never be carried out on live equipment. 2. Only qualified and authorized personnel shall work on electrical equipment. 3. A “Safe System of Work” shall be implemented and documented (where necessary) i.e. work permit 4. Local testing shall be carried out (competent person) to ensure that equipment is isolated |
| Fire and/or Explosion | 1. Can occur through electrical test equipment generating sparks in areas of potentially flammable and/or explosive materials. | 1. Work shall never be carried out on live equipment. 2. Only qualified and authorized personnel shall work on electrical equipment. 3. Personnel shall ensure that circuits are isolated atboth ends before testing. |
| Emergencies | 1. The potential of accidents/incidents and/or dangerous occurences can be increased if suitable and sufficient emergency procedures have not been implemented prior to work commencement. | 1. Emergency procedures shall be in place prior to work cemmencment covering fire fighting equipment, access/egress routes, trained first aiders, etc. 2. Regular drills shall be utilized to ensure that the emergency procedures which have been implemented are suitable and sufficient. |
| Burns | 1. Can occur during the process of electric shock and are normally very severe. | 1. Work shall never be carried out on live equipment. 2. Only qualified and authorized personnel shall work on electrical equipment. 3. A “safe system of work” shall be implemented where necessary (i.e. Work permit) 4. Local testing shall be carried out to ensure that equipment is isolated. 5. Personnel shall ensure that all burns, etc. are treated immediately by a trained first aider. |

제주도 서쪽 비양도라는 섬이 있습니다. . 비양도는 제주시 한림읍 비양리 위치해 있으며, 하늘에서 날오온 섬이라는 의미를 지니고 있습니다. 비양도는 한림항에서 약 1.1km 떨어져 있으며, 섬의 모양은 원형에 가깝고 약 2000여명의 주민이 거주하고 있습니다. 비양도의 중앙에는 해발 114m 높이의 비양봉 본석구가 있고, 서쪽 해안에는 제주도에서 가장 큰 초대형 화산탄들이 분포하고 있습니다. . 섬의 북쪽 해안에는 호니토(homito)로 알려진 굴뚝모양의 바위들이 약 20여기 분포하고 있다. 호니토는 용암이 흐르다가 습지 등의 물을 만나 수증기와 용암이 뒤섞여 분수처럼 솟구쳐 나와 쌓여 만들어졌으며, 천연기념물 제439호로 지정되어 있습니다. . 섬의 동쪽에는 펄렁못 엄습지와 마을 신당이 위치해 있습니다. 최근까지 비양도는 약 1,000년 전에 분출한 섬으로 알려져 왔으나 용암의 나이를 분석한 결과 27,000년 전에 형성된 것으로 조사되었습니다. . …
