SECTION III-FIRE AND EXPLOSION HAZARD DATA |
On Flammable; Welding arc and sparks can ignite combustibles and
flammable products. See Z49.1 referenced in Section VI. |
SECTION IV-HEALTH HAZARD DATA |
Threshold Limit Value: The ACGIH recommended general limit for
Welding Fume NOC-(Not Otherwise Classified) is 5 mg/m3.
ACGIG-1999 preface states that the TLV-TWA should be used as guides in
the control of health hazards and should not be used as fine lines
between safe and dangerous concentrations. See Section V for specific
fume constituents which may modify this TLV. Threshold Limit Values are
figures published by the American Conference of Government Industrial
Hygienists. Units are milligrams per cubic meter of air.
Effects of Overexposure: Electric arc welding may create one or more of
the following health hazards:
Fumes and Gases can be dangerous to your health. Common entry is by
inhalation. Other possible routes are skin contact and ingestion.
Short-term (acute) overexposure to welding fumes may result in
discomfort such as metal fume fever, dizziness, nausea, or dryness or
irritation of nose, throat, or eyes. May aggravate pre-existing
respiratory problems (e.g. asthma, emphysema). Chromates present in the
fume have been known to cause severe irritation of the bronchial tubes
and lungs. Asthma has been reported. Exposure to extreme cases it can
cause loss of consciousness and death.
Long-term (chronic) overexposure to welding fumes can lead to siderosis
(iron deposits in lung) and may affect pulmonary function. Manganese
overexposure can affect the central nervous system, resulting in
impaired speech and movement. Bronchitis and some lung fibrosis have
been reported. Chromates may cause ulceration and perforation of the
nasal septum. Liver damage and allergic reactions, including skin rash,
have been reported. Repeated exposure to fluorides may cause excessive
calcification of the bone and calcification of ligaments of the ribs,
pelvis and spinal column. May cause skin rash. Chromium and nickel and
their compounds are on the IARC (International Agency for Research on
Cancer) and NTP (National Toxicology Program) Lists as posing a
carcinogenic risk to humans. WARNING: This product contains or produces
a chemical known to the State of California to cause cancer and birth
defects (or other reproductive harm). (California Health & Safety Code
Section 25249.5 et seq).
Arc Rays can injure eyes and burn skin. Skin cancer has been reported.
Electric Shock can kill. If welding must be performed in damp locations
or with wet clothing, on metal structures or when in cramped positions
such as sitting, kneeling or lying, or if there is a high risk of
unavoidable or accidental contact with workpiece, use the following
equipment: Semiautomatic DC Welder, DC Manual (Stick) Welder., or AC
Welder with Reduced Voltage Control.
Emergency and First Aid Procedures: Call for medical aid. Employ first
and techniques recommended by the American Red Cross.
IF BREATHING IS DIFFICULT give oxygen. IF NOT BREATHING employ CPR
(Cardiopulmonary Resuscitation) techniques.
IN CASE OF ELECTRICAL SHOCK, turn off power and follow recommended
treatment. In all a physician. |
SECTION V – Reactivity Data
|
Hazardous Decomposition Products: Welding fumes and gases cannot be
classified simply. The composition and quantity of both are dependent
upon the metal welded, the process, procedure and electrodes used.
Other conditions which also influence the composition and quantity of
the fumes and gases to which workers may be exposed include: coatings on
the metal being welded (such as paint, plating., or galvanizing), the
number of welders and the volume of the worker area, the quality and
amount of ventilation, the position of the welder's head with respect to
the fume plume, as well as the presence of contaminants in the
atmosphere (such as chlorinated hydrocarbon vapors from cleaning and
degreasing activities.)
When the electrode is consumed, the fume and gas decomposition products
generated are different in percent and form from the ingredients listed
in Section II. Decomposition products of normal operation include those
originating from the volatilization, reaction, or oxidation of the
materials shown in Section II, plus those from the base metal and
coating, etc., as noted above.
Reasonably expected fume constituents of this product would include:
Primarily iron oxide and fluorides; secondarily complex oxides of
aluminum, calcium, chromium, magnesium, manganese, nickel, potassium,
silicon, sodium and zirconium when used with recommended Lincolnweld
fluxes. Primarily iron oxide, manganese oxide, and complex chromium
oxides; secondarily complex oxides of molybdenum (316 types) and nickel
when used with gas shielding.
Maximum fume exposure guideline for this product (based on Cr(VI)
content) is 0.8 milligrams per cubic meter for submerged arc and 3.0
milligrams per cubic meter (based on Cr(III) content) when used with gas
shielding for GMAW and 1.5 milligrams per cubic meter (based) on
manganese content) when used for CTAW. See MSDS for flux being used.
The OSHA PEL (Permissible Exposure Limit) is a ceiling value that shall
not be exceeded at any time.
Keep exposure as low as possible. Indoors, use local exhaust; outdoors,
a respirator may be required.
Gaseous reaction products may include carbon monoxide and carbon
dioxide. Ozone and nitrogen oxides may be formed by the radiation from
the arc.
Determine the composition and quantity of fumes and gases to which
workers are exposed by taking an air sample from inside the welder's
helmet if worn or in the worker's breathing zone. Improve ventilation if
exposures are not below limits. See ANSI/AWS F1.1,F1.2,F1.3,F1.4 and
F1.5, available from the American Welding Society, 550 N.W. LeJeune
Road, Miami, FL 33126.
| SECTION VI AND VII
CONTROL MEASURES AND PRECAUTIONS FOR SAFE HANDLING AND USE |
Read and understand the manufacturer's instruction and the
precautionary label on the product, Request Lincoln Safety Publication
E205. See American National Standard Z49.1, 'Safety In Welding, Cutting
and Allied Processes' published by the American Welding Society, 550
N.W. LeJeune Road, Miami, FL, 33126 and OSHA Publication 2206
(29CFR1910), U.s. Government Printing Office, Superintendent of
Documents, P.O.Box 371954, Pittsburgh, PA 15250-7954 for more details on
many of the following: | Ventilation: Use enough
ventilation, local exhaust at the arc, or both to keep the fumes and
gases from the worker's breathing zone and the general area. Train the
welder to keep his head out of the fumes. Keep exposure as low as
possible. | Respiratory Protection: Use respirable
fume respirator or air supplied respirator when welding in confined
space or general work area when local exhaust or ventilation does not
keep exposure below TLV. | Eye Protection: Wear
helmet or use face shield with filter lens shade number 12 or darker.
Shield others by providing screens and flash goggles. ( ) No specific
recommendation for submerged arc.
| Protective Clothing: Wear hand, head, and body
protection which help to prevent injury from radiation, sparks and
electrical shock. See Z49.1. At a minimum this includes welder's gloves
and a protective face shield, and may include arm protectors, aprons,
hats, shoulder protection, as well as dark substantial clothing, Train
the welder not to permit electrically live parts or electrodes to
contact skin… or clothing or gloves if they are wet. Insulate from work
and ground. | Disposal Information: Discard and
product, residue, disposable container, or liner as ordinary waste in
and environmentally acceptable manner according to Federal, State and
Local Regulations unless otherwise noted. |
