Safety Engineering
This field of engineering has its object the prevention of accidents. Safety engineering develops methods and procedures to safeguard workers of dangerous occupations. Safety engineering is necessary in any productions.

Welding process of any kind can be dangerous not only to the operator but to any person situated near equipment, if safety rules are not strictly observed. They include: precautionary measures for an operator, fire prevention and the right arrangement of the welding process, electromagnetic compatibility.

Safety measures for an operator.

Operators should ptotect their body by wearing closed, non-flammable protective clothing, without pockets or turned up trousers: a non-flammable helmet, safety glasses, protective sleeves, shoulder guard, three or five-fingered welding gloves, leather apron, and a shin guard.

Safety measures for the welding process.

The welding process must be performed on metal coatings thoroughly cleaned from layers of rust or paint, to avoid production of harmful fumes.

Wealding should never be done on metals or coated metals containing zinc, mercury, chromium, graphite, lead, cadmium or beryllium unless the operator and the people standing at the same area use an air-supplied respirator.

Before connecting the power source to the line, closely follow the instructions: a two-pole plug compatible with above-mentioned socket.

When working in a confined space, the power source must be kept outside the welding area and the ground cable should be fixed to the work piece. Never work in a damp or wet area.

The power source must never be operated without its panels; this could cause serious injury to the operstor and damage the equipment.

Fire prevention.

Fire prevention devices should be available near the welding area. Remove all combustible materials from the welding area. Use the correct shielding gas for welding process, make sure that the regulator mounted Electromagnetic Compatibility

Before installing a power supply cables, check the following:

- make sure that there are no other power supply cables, control lines, telephones cables or other devices
- telephones, TV, computers or other control systems are not in the working area
- people with pace-maker or hearing-prosthesis are far from the power source
- a qualified person first aid technique is present in the working area a person is unconscious and electric shock is suspected, don`t touch the person. Disconnect power from the machine and then use First Aid. Dry wood and other insulating materials can be used to move cables away from the person.
