3.4 Risk of poisoning
Gases and fumes that are harmful when inhaled for a longer time can be released while
welding.
Because of this, the following safety guidelines have to be observed:
Ensure that you have adequate ventilation for the work area.
During the processing of materials such as, beryllium, potassium, zinc, or galvanized and painted
pieces, you must set up forced ventilation.
The operator has to protect his airway with appropriate equipment.
Wherever a sufficient air supply is ensured, you must use respirators and additional air supply.
In small rooms (in boilers, in the ditch, etc.), the welders have to be backed up by another person.
Provided that all requirements are met to prevent accidents.
Weld never near degreasing and painting, because there may be released bleach-water, which
transform under the influence of heat into phosgene, a highly toxic gas.
The signs of inadequate ventilation or a possible poisoning are charms in the eyes, nose and
throat. In this case, you have to interrupt the welding work and ventilate the work area. If you feel
uncomfortable anyway stop the welding work.
3.5 Installation of the power source
When setting up the welding machine the following requirements have to be obeyed:
All switch ports and devices must be accessible.
Thus, the source can be adequately ventilated, never set up the device in a narrow space. Avoid
dirty and dusty areas, so the device can absorb no foreign body.
The unit including all cables should not impede the ability to work and the passage to other rooms.
The unit must be secured against falling down.
Setting up objects higher, increases the risk that it may fall off during the work.
