The exposure limit for welding fume has been established at 5 mg/m3 with OSHA's 
PEL and ACGIH's TLV. The individual complex compounds within the fume may have 
lower exposure limits than the general welding fume PEL/TLV. An Industrial 
Hygienist, the OSHA Permissible Exposure Limits for Air Contaminants (29 CFR 
1910.1000), and the ACGIH Threshold Limit Values should be considered to 
determine the specific fume constituents present and their respective exposure 
limits. 

SECTION 3 - PHYSICAL / CHEMICAL CHARACTERISTICS

Welding consumables applicable to this sheet are solid and nonvolatile as 
shipped. 

SECTION 4 - FIRE AND EXPLOSION HAZARD DATA

Welding consumables applicable to this sheet as shipped are non reactive, 
nonflammable, non explosive and essentially non hazardous until welded. Welding 
arcs and sparks can ignite combustibles and flammable products. See American 
National Standard Z49.1 referenced in Section 7. 

SECTION 5 - REACTIVITY DATA
HAZARDOUS DECOMPOSITION PRODUCTS
Welding fumes and gases cannot be classified simply. The composition and 
quantity of both are dependent upon the metal being welded, the process, 
procedures and electrodes used. Most fume ingredients are present as complex 
oxides and compounds and not as pure metals. 
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 work 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 2. Decomposition products of normal operation include those originating 
from the volatilization, reaction or oxidation of the materials shown in Section 
2, plus those from the base metal and coating, etc, as noted above. 
Reasonably expected constituents of the fume would include: Primarily - complex 
oxides of iron: Secondarily - complex oxides of manganese, silicon and copper. 
Molybdenum compounds may be present in ER80S-D2.
Monitor for the materials identified in Section 2. Fumes from the use of this 
product may contain copper, manganese compounds, and amorphous silica whose 
exposure limits are lower than the 5 mg/m3 PEL/TLV for general welding fume. 
Gaseous reaction products may include carbon monoxide and carbon dioxide. Ozone 
and nitrogen oxides may be formed by the radiation from the arc. 
One recommended way to determine the composition and quantity of fumes and gases 
to which workers are exposed is to make an air sample inside the welder's helmet 
if worn or in the worker's breathing zone. [See ANSI/AWS F1.1 available from the 
"American welding society", P.O. Box 351040, Miami, FL 33135. Also, from AWS is 
F1.3 "Evaluating Contaminants in the Welding Environment. - A Sampling Strategy 
Guide", which gives additional advice on sampling.]

SECTION 6 - HEALTH HAZARD DATA

EFFECTS OF OVEREXPOSURE;
Electric arc welding may create one or more of the following health hazards:
ARC RAYS can injure eyes and burn skin. 
ELECTRIC SHOCK can kill. See Section 7.
FUMES AND GASES can be dangerous to your health. 
PRIMARY ROUTES OF ENTRY are the respiratory system, eyes and/or skin.


SHORT-TERM (ACUTE) OVEREXPOSURE EFFECTS;
WELDING FUMES - May result in discomfort such as dizziness, nausea or dryness or 
irritation of nose, throat or eyes.
IRON, IRON OXIDE - None are known. Treat as nuisance dust or fumes. 
MANGANESE - Metal fume fever characterized by chills, fever, upset stomach, 
vomiting, irritation of the throat and aching of body. Recovery is generally 
complete within 48 hours of the overexposure. 
SILICA (AMORPHOUS) - Dust and fumes may cause irritation of the respiratory 
system, skin and eyes. 
COPPER - Metal fume fever characterized by metallic taste, tightness of chest 
and fever. Symptoms may last 24 to 48 hours following overexposure.
MOLYBDENUM - Irritation of the eyes, nose and throat. 

LONG-TERM (CHRONIC) OVEREXPOSURE EFFECTS;
WELDING FUMES - Excess levels may cause bronchial asthma, lung fibrosis, 
pneumoconiosis or "siderosis" 
IRON, IRON OXIDE FUMES - Cab cause siderosis (deposits of iron in lungs) which 
some researches believe may affect pulmonary function. Lungs will clear in time 
when exposure to iron and its compounds cases. Iron and magnetite (Fe3O4) are 
not regarded as fibrogenic materials. 
MANGANESE - Long-term overexposure to manganese compounds may affect the central 
nervous system. Symptoms may be similar to Parkinson's Disease and can include 
slowness, changes in handwriting, gait impairment, muscle spasms and cramps and 
less commonly, tremor and behavioral changes. Employees who are overexposed to 
manganese compounds should be seen by a physician  for early detection of 
neuralgic problems. 
SILICA (AMORPHOUS) - Research indicates that silica is present in welding fume 
in the amorphous form. Long term overexposure may cause pneumoconiosis. 
Non crystalline forms of silica (amorphous silica) are considered to have little 
fibroric potential. 
COPPER - Copper poisoning has been reported in the literature from exposure to 
high levels of copper. Liver damage can occur due to copper accumulating in the 
liver characterized  by cell destruction and cirrhosis. High levels of copper 
may cause anemia and jaundice. High levels of copper may cause central nervous 
system damage characterized by nerve fiber separation and cerebral degeneration. 
MOLYBDENUM - Prolonged overexposure ay result in loss of appetite, weight loss, 
loss of muscle coordination, difficulty in breathing and anemia. 

MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Persons with pre-existing impaired lung functions (asthma-like conditions).

EMERGENCY AND FIRST AID PROCEDURES;
Call for medical aid. Employ first aid techniques recommended by the American 
Red Cross.
Eyes and Skin: If irritation or flash burns develop after exposure, consult a 
physician. 

CARCINOGENICITY:
Welding fumes must be considered as possible carcinogens under OSHA (29 CFR 
1910.1200). 

CALIFORNIA PROPOSITION 65;
WARNING: This product, when used for welding or cutting, produces fumes or gases 
which contain chemicals known to the State of California to cause birth defects 
and, in some cases, cancer.  (California Health & Safety Code Section 25249.5 et 
seq.)

SECTION 7 - PRECAUTIONS FOR SAFE HANDLING & USE/APPLICABLE CONTROL MEASURES

Read and understand the manufacturer's instructions and the precautionary label, 
on the product. See American National Standard Z49.1: Safety in Welding and 
Cutting published by the American Welding Society. P.O. Box 351040, Miami, FL 
33135 and OSHA Publication 2206 (29 CFR 1910), U.S. Government Printing Office. 
Washington
DC 20402 for more detail on any of the following. 
VENTILATION: Use enough ventilation, local exhaust at the arc or both, to keep 
the fumes and gases below PEL/TLVs in the worker's breathing zone and the 
general area. Train the welder to keep his head out of the fumes. 
RESPIRATORY PROTECTION; Use NIOSH approved or equivalent fume respirator or air 
supplied respirator when welding in confined space or where local exhaust or 
ventilation does not keep exposure below PEL/TLVs.
EYE PROTECTION; Wear helmet or use face shield with filter lens. As a rule of 
thumb begin with Shade Number 14. Adjust if needed by selecting the next lighter 
and/or darker shade number. Provide protective screens and flash goggles, if 
necessary, to shield others. 
PROTECTIVE CLOTHING; Wear hand, head and body protection which help to prevent 
injury from radiation, sparks and electrical shock. See ANSIZ49.1. 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 non synthetic 
clothing. Train the welder not to touch live electrical parts and to insulate 
himself from work and ground. 
PROCEDURE FOR CLEANUP OF SPILLS OR LEAKS; Not applicable. 
WASTE DISPOSAL; Prevent waste from contaminating surrounding environment. 
Discard any product, residue, disposable container or liner in an 
environmentally acceptable manner, in full compliance with Federal, State and 
Local regulations. 
SPECIAL PRECAUTIONS (IMPORTANT): Maintain exposure below the PEL/TLVs. Use 
industrial hygiene monitoring to ensure that your use of this material does not 
create exposures which exceed PEL/TLVs. Always use exhaust ventilation. Refer to 
the following sources for important additional information. ANSI Z49.1 from the 
American Welding Society, P.O. Box 351040 Miami, FL 33135 and OSHA (29 CFR 1910)
