SMAW operation, must pay attention to safety and protection, security and protection technology mainly to avoid electric shock, arc radiation, fire and explosion and toxic gases and smoke poisoning.

1 avoid electric shock

In the welding of the welding rod, the output voltage of the electric network and the output voltage of the welding machine and the voltage of the portable lamp will have the risk of electric shock. Therefore, to take measures to avoid electric shock. Or zero. Welding cable holder and insulation to good, if damaged, should be timely repair. When welding the welding rod, wear the insulated shoes, and wear the gloves. In the boiler, pressure vessel, pipe, narrow and wet trench in the welding, to have an insulation pad, and some people in the external monitoring. When using a portable lamp, the voltage does not exceed the safe voltage of 36V, high above 12V. High altitude operation, power required in high voltage line 5m or within 2.5m, low line operation, and hang warning signs in the gates, guardianship. In case of electric shock, to quickly cut off the power, and timely rescue.

2 avoid arc radiation

The intense arc welding arc and UV damage to the eyes and skin. SMAW, must be used with welding goggles and masks, wearing overalls, wear a glove. People should pay attention to prevent welding operation, mutual influence, should set the arc shield or take other measures to prevent cross effects of arc radiation.

Isolated from mars. When more than 6 gale, did not take effective measures to safely stop the welding operation in the open and high-altitude operations, welding operations around the site should have fire fighting equipment. The end of the welding operation should be pulled, and the timely liquidation of the site, to eliminate the fire.

3 avoid fire

In the welding operation point of fire within lOm and aerial below and Mars and welding range should be thoroughly eliminate organic dust, wood, sawdust, cotton yarn, cotton yarn of straw hay, oil, gasoline, paint and other flammable materials. If not the withdrawal of combustible materials, such as wood, without removal of insulation of combustible materials, should take measures to secure peace, such as water spray, wet sack, asbestos cloth cover.
