1.4 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.
1.5 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.
