SECTION IV (FIRE AND EXPLOSION HAZARD DATA) 

Nonflammable. Welding arc and sparks can ignite combustibles. Refer to American National Standard Z-49.1 for fire prevention 
during welding. 

SECTION V (REACTIVITY DATA) 

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. 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 welds and volume of the work area, quality and amount of ventilation, 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 percentage from 
the ingredients listed in Section II. Fume and gas decomposition products, not the ingredients in the electrode, are important. 
Decomposition products generated in normal operations include those originating from the volatilization, reaction, or oxidation 
of the materials shown in Section II plus those from the base metal, coating, etc., as noted above. 

It is understood, however, that the elements and/or oxides to be mentioned are virtually always present as complex 
oxides and not as metals (Characterization of Arc Welding Fume: American Welding Society). The elements or oxides listed 
below correspond to the ACGIH categories located in “TLV Threshold Limit Values for Chemical Substances and Physical 
Agents in the workroom environment.” 

Reasonably expected constituents of the fume would include: complex oxides of copper, chromium, manganese, and 
silicon. The limits of vapor for chromium (Cr) (0.5 mg/m2) can be reached before the general limit of vapor of 5 mg/m2. 
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 to which workers are exposed is to take 
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.) At a minimum, materials 
listed in this section should be analyzed for the following: 

SECTION VI (HEALTH HAZARD DATA) 

Threshold Limit Value: The ACGIH recommended general limit for welding fume NOC (Not Otherwise Classified) is 
5 mg/m2. ACGIH 1984-85 preface states, “The TLV-TWA should be used as guides in the control of health hazards and 
should not be used as firm lines between safe and dangerous concentrations.” See Section V for specific fume constituents 
which may modify this TLV. 

Effects of Overexposure: 

FUMES AND GASES can be dangerous to your health. Primary route of exposure is inhalation of fumes. Preexisting 
respiratory or allergic conditions may be aggravated in some individuals. 


WARNING: DO NOT BREATHE FUMES! 
SHORT-TERM (ACUTE) OVEREXPOSURE to welding fumes may result in discomfort such as dizziness, nausea, or 
dryness or irritation of the nose, throat or eyes. 

CONTINUED ON THE BACK 


LONG-TERM (CHRONIC) OVEREXPOSURE may lead to siderosis (iron deposits in the lungs) and is believed by some 
investigators to affect pulmonary functions. Beryllium can lead to respiratory symptoms, weakness, fatigue, weight loss, 
cumulative lung damage (Beryllosis), and is a suspected carcinogen. Chromium: ulceration and perforation of nasal septum. 
Respiratory irritation may occur with symptoms resembling asthma. Studies have shown that chromate production workers 
exposed to hexavalent chromium compounds have an excess of lung cancers. Chromium (VI) compounds are more readily 
absorbed through the skin than chromium (III) compounds. Good practice requires the reduction of employee exposure to 
chromium (III) and (VI) compounds. Cobalt should be considered as a possible carcinogen. 
ARC RAYS can injure eyes and burn skin. 
ELECTRIC SHOCK can kill. See Section VII. 
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 burns develop after exposure, consult a physician. 
CARCINOGENICITY: Chromium VI, cobalt, beryllium, nickel and its compounds should be considered as 
possible carcinogens. 
WARNING: CALIFORNIA PROPOSITION 65: This product, when used for welding, soldering, brazing, cutting and other 
metal working or flame processes, produces fumes, particulates, residues and other by-products which contain chemicals 
known to the State of California to cause cancer and birth defects or other reproductive harm. 


WARNING: This product 
contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. 
SECTION VII (PRECAUTIONS FOR SAFE HANDLING AND USE/APPLICABLE CONTROL MEASURES) 

Read and understand the manufacturer’s instructions and the precautionary label on the product. (See American National 
Standard Z-49.1, “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), US Government Printing Office, Washington, DC 20402 for more details 
on the following): 

VENTILATION: Use enough ventilation, local exhaust at the arc, or both, to keep the fumes and gases below the TLV’s 
in the worker’s breathing zone and the general area. Train the welder to keep his head out of the fumes. 


WARNING: DO NOT BREATHE FUMES! 
RESPIRATORY PROTECTION: Use NIOSH approved or equivalent respirable fume respirator or air supply respirator 
when welding in confined space or where local exhaust or ventilation does not keep exposure below TLV. 

EYE PROTECTION: Wear helmet or use face shield with filter lens. As a rule of thumb, begin with shade #14. Adjust if 
needed by selecting the next lighter or darker shade number. 

PROTECTIVE CLOTHING: Wear hand, head, and body protection which help to prevent injury from radiation, sparks 
and electrical shock. See ANSI Z-49.1. 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 substantial 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 and in full compliance with federal, state and local regulations. 

SPECIAL PRECAUTIONS: IMPORTANT. MAINTAIN EXPOSURE BELOW PEL/TLV. USE INDUSTRIAL HYGIENE 
MONITORING TO ENSURE THAT YOUR USE OF THIS MATERIAL DOES NOT CREATE EXPOSURES WHICH EXCEED 
PEL/TLV. Always use exhaust ventilation. Refer to the following sources for important additional information: ANSI Z-49.1.
