Welding Health and Safety 焊接作业的健康与安全 Hazards 危害性 •Welding has both “Apparent” hazards and “Hidden” hazards. Apparent hazards are those which can be easily identified. Hidden hazards are those not seen and often forgotten. 焊接分明显的危害和隐藏的危害，明显的危害是容易鉴定而隐藏的危害是不明 显而且容易忽略的。 •Some of these are: ~Electrical Shock 触电 ~Over exposure to arc radiation 电弧光辐 ~Fumes and gasses 有害的烟和气 ~Burns and fire 灼伤和火灾 ~Compressed gas cylinders 压力容器 ~Noise 噪音 EHS俱乐部 ①Electrical Safety 电气安全 •Electric shock and electrocution are possible hazards with all welding processes. 在整个焊接过程中，触电和电击是可 能存在的危害。 EHS俱乐部 ①Electrical Safety 电气安全 •There are two different areas of concern. 有两个不同的区域需要注意。 The primary side: The secondary side: 主要方面: 次级方面: •Exposed wires on the •Fuse or Breaker panel welding lead. 保险丝或者断路面板 焊接端面上的裸线 •Power Supply cables •Contact with the 电源线 electrode and the work •Internal parts of the piece. power source 电极和工件之间的连接 电源内部零件
