Skin contact: |
For skin burns from arc radiation, promptly flush with cold water. Get
medical attention for burns or irritations that persist. To remove dust or
particles wash with mild soap and water. |
Electric shock: |
Disconnect and turn off the power. Use a nonconductive material to
pull victim always from contact with live parts or wires. If not breathing,
begin artificial respiration, preferably mouth-to-mouth. If no detectable
pulse, begin Cardio Pulmonary Resuscitation (CPR). Immediately call a
physician. |
General: |
Move to fresh air and call for medical aid. |
|
|
05. Fire fighting measures |

Keep separate from chemical substances like acids and strong bases,
which could cause chemical reactions. |
|
|
08. Exposure controls/ Personal protection |
General: |
Avoid exposure to welding fumes, radiation, spatter, electric shock,
heated materials and dust. |
Engineering measures: |
Ensure sufficient ventilation, local exhaust, or both, to keep welding
fumes and gases from breathing zone and general area. Keep working
place and protective clothing clean and dry. Train welders to avoid contact
with live electrical parts and insulate conductive parts. Check condition
of protective clothing and equipment on a regular basis. |
Personal protective equipment: |
Use respirator or air supplied respirator when welding or brazing in a
confined space, or where local exhaust or ventilation is not sufficient to
keep exposure values within safe limits. Use special care when welding
painted or coated steels since hazardous substances from the coating
may be emitted. Wear hand, head, eyes, ear and body protection like
welders gloves, helmet or face shield with filter lens, safety boots,
apron, arm and shoulder protection. Keep protective clothing clean and
dry. Use industrial hygiene monitoring equipment to ensure that exposure
does not exceed applicable national exposure limits. The following
limits can be used as guidance. Unless noted, all values are for 8 hour
time weighted averages (TWA). For information about welding fume
analysis refer to section 10. |

Refer to applicable national exposure limits for fume compounds, including
those exposure limits for fume compounds found in section 8. A
significant amount of the chromium in the fumes can be hexavalent
chromium, which has a very low exposure limit in some countries.
Manganese and nickel have low exposure limits, in some countries,
that may be easily exceeded. Reasonably expected gaseous products
would include carbon oxides, nitrogen oxides and ozone. Air contaminants
around the welding area can be affected by the welding process
and influence the composition and quantity of fumes and gases produced.
|
|
|
11. Toxicological information |
General: |
Inhalation of welding fumes and gases can be dangerous to your
health. Classification of welding fumes is difficult because of varying
base materials, coatings, air contaminations and processes. The International
Agency for Research or Cancer has classified welding fumes
as possibly carcinogenic to humans (Group 2B). |
Acute toxicity: |
Overexposure to welding fumes may result in symptoms like metal
fume fever, dizziness, nausea, dryness or irritation of the nose, throat
or eyes. |
Chronic toxicity: |
Overexposure to welding fumes may affect pulmonary function. Prolonged
inhalation of nickel and chromium compounds above safe exposure
limits can cause cancer. Overexposure to manganese and
manganese compounds above safe exposure limits cam cause irreversible
damage to the central nervous system, including the brain,
symptoms of which may include slurred speech, lethargy, tremor, muscular weakness, psychological disturbances and spastic gait. Prolonged
inhalation of titanium dioxide above safe exposure limits can
cause cancer. Inhalable quartz is a respiratory carcinogen however the
process of welding converts crystalline quartz to the amorphous form
which is not considered to be a carcinogen. |
|
|
12. Ecological information |
Welding consumables and materials could degrade/ weather into components originating from the consumables
or from the materials used in the welding process. Avoid exposure to conditions that could
lead to accumulation in soils or groundwater. |
|
|
13. Disposal considerations |
Discard any product, residue, disposable container or liner in an environmentally acceptable manner,
in full compliance with federal and local regulations. Use recycling procedures if available. USA
RCRA: Unused products or product residue containing chromium is considered hazardous waste if
discarded, RCRA ID characteristic Toxic Hazardous Waste D007. Residues from welding consumables
and processes could degrade and accumulate in soils and groundwater.
