I. In the course of the aloft work, the worker should use safety to avoid dropping.
2. Beware of the arc light
A. When you observe the arc light during the welding process, you should wear a mask
with black glass. Appropriate flame-retardant material should be used to protect other
persons and warn them not to observe the welding arc light or to keep away from the
arc light, the spatter or hot workpiece.
B. The mask with black glass and cover plate is to protect your eyes from burning by the
spark or arc light. The mask and black glass must meet the requirements listed in the
standard ANSIZ87.1.Wear clothes made of refractory materials to protect skins from
burning by the spark or the arc light.
3. Beware of the welding fume
A. The exhausted gas during the welding process is harmful to our healthy, thus we
should avoid inhaling these gases. When we conduct the welding operation, The
head should be avoided to facing the welding fume and the exhausted gas.
Meanwhile, it is necessary to install enough ventilation equipments to keep these
gases away from the breathing zone. In the welding process of stainless steels, or
layer rich in cadmium (refer to corresponding items on containers and MSDS), or
steels containing lead and plated with cadmium with the manual metal arc welding,
some poisonous gas and fume will be generated, and then some specific ventilation
equipments are needed. In these conditions, try to reduce the direct exposure and
local gas exhaustion or mechanical ventilation equipments should be applied when it
is lower than the lowest value. In the restrict zones or outdoors, protection masks are
needed. It also needs to take protection measures in the course of welding
galvanized steels.
B. The welding operations are forbidden near the steam of chloridized hydrocarbons
generated in the course of the lubrication, cleanliness or spraying operations. The arc
heat and arc light will react with these chloridized hydrocarbon to generate gaseous
phosgene and stimulus with virulent property.
C. The shielding gas used for the welding technology is harmful to our body and even
leads to death. It is necessary to install enough ventilation equipments to ensure the
breathing safety, especially in narrow working zone.
D. Read through and understand the supplied manuals for the equipment and
consumables, including the material safety databases (MSDS). And then, be sure to
comply with the employer’s safety regulations. The MSDS can be obtained from the
distributors or the manufacturers.
4. Fire prevention
A. Keep combustibles away from the welding area. If it is impossible, they should be
shaded to avoid fires caused by the welding spatter. Keep in mind that welding
spatters and hot material can easily flow though the slit in the welding area and then
