Section IV 鈥? Fire and Explosion Hazard
Welding arc and sparks, and the use of oxy-fuel torches, can ignite combustibles and flammable. Refer to American
National Standard Z49.1 for fire prevention during the use of welding and allied procedures.
Section V 鈥? Health Hazard Data
Use of this product in welding and brazing operations can result in exposure to airborne metal particulates and fumes.
Section 2 lists specific hazardous ingredients and exposure limits. Section 6 lists exposure limits for hazardous reaction
products that might be formed by welding and high temperature cutting.
IMPORTANT: Determine actual exposure by industrial monitoring.
Primary routes of exposure are inhalation of fumes, gases, or particulates. Absorption through the skin is unlikely.
Welding Fumes
The constituents of the fume are generally different from the ingredients listed in Section 2 and may include oxides of
the metals, chromates, fluorides, and complex metallics. The gases may include carbon monoxide, ozone, and oxides
of nitrogen. Chlorinated solvents may be decomposed by the arc into toxic gases such as phosgene. The chemicals
listed in Table 6a have low PEL鈥檚/TLV鈥檚 and represent potential health hazards. Postle Industries recommends
monitoring o these chemicals.

POSSIBLE SIGNS AND SYMPTOMS OF EXPOSURE TO DUST, WELDING FUME AND GASES:
SHORT TERM EXPOSURE:
2
Metallic taste; nausea; vomiting, fatigue/drowsiness, dizziness, weakness, headache, tightness of chest; metal fume
fever; coughing, irritation of eyes, irritation to mucous membranes, throat and skin; loss of consciousness or death due
to welding gases and lack of oxygen. Welding fumes can also be a respiratory and pulmonary irritant.
LONG TERM EXPOSURE:
Adverse effects may result from long time exposure to welding fumes, gases, or dusts. These effects may include skin
sensitization, neurological damage, and respiratory disease such as bronchial asthma, lung fibrosis or pneumoconiosis.
Chronic exposure to copper, zinc and manganese may cause metal fume fever. Symptoms of metal fume fever include
fever, fatigue, dryness of throat, head and body ache, chills. Chronic exposures may affect the central nervous system
leading to emotional disturbances, gait and balance difficulties and paralysis. Overexposure to copper may result in
skin and hair discoloration.
Nickel and chromium when present in welding electrodes arc of special interest. The OSHA Hazard Communication
Standard (29 CFR 1910.1200) deems them to be human carcinogens. They are on the IARC and NTP lists of suspect
or proven carcinogens. Also, OSHA regards some Chromium VI compounds as carcinogenic. Certain chromium and
nickel compounds have been clearly shown to be animal and human carcinogens, however these compounds have not
been found in the welding fumes. Nevertheless, the welding fume should be monitored for chromium and nickel and
exposures must be maintained below the levels specified in the Sections 2 and 6. Studies have shown the chromate
production workers exposed to hexavalent chromium compounds have excess in lung cancer. 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.
Aggravation of pre-existing respiratory of allergic conditions may occur in some workers.
FIRST AID:
Ingestion: Ingestion is unlikely. Seek medical help if large quantities of product are ingested
Inhalation: Remove from exposure and obtain medical attention. If victim is unconscious, administer oxygen. If not
breathing, resuscitate immediately.
Skin Contact: Wash thoroughly with soap and water. If rash develops, call a physician.
Eye Contact: Flush with water for at least 15 minutes. Seek medical help if required.
VI 鈥? Reactivity Data
Fumes and gases from welding and high temperature cutting cannot be classified simply. The composition and
quantity of both depend on 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 welding and the volume of
the work area, the quality and amount of ventilation, the position of the welder鈥檚 head with respect to the fume plume,
as well as the presence of contaminates in the atmosphere (such as chlorinated hydrocarbon vapors from cleaning and
degreasing activities.)
Most fume ingredients are present in complex combinations, rather than as separate compounds. Excessive
overexposure may produce the effects outlined in Section 6.
Section VII 鈥? Spill or Leak Procedures
Product is a non-hazardous solid. No special precautions are required for spills of bulk material. Scrap metal can be
reclaimed for reuse. Follow Federal, State and Local regulations regarding disposal.
Section VIII 鈥? Special Protection Information
Ventilation: Use enough ventilation, local exhaust at the arc (or flame), or both, to keep the fumes and gases below the
PEL鈥檚, TLV鈥檚 and STEL鈥檚 in the workers breathing zone and general area. Train the employee to keep his head out of
the fumes. See ANSI/ASC Z49.1 Section 5.
Respirator Protection: Use respirable fume respirator or air-supplied respirator when welding in confined area, or
where local exhaust or ventilation does not keep exposure below TLV/PEL. Respirator selection and use should be
based on contaminant type, form and concentration. Follow OSHA 1910.134, OSHA 1910.1026, ANSI Z88.2 and
good industrial Hygiene practice.
IMPORTANT: SPECIAL VENTILATION AND/OR EXHAUST REQUIRED: Overexposure to manganese can
irreversibly affect the central nervous system resulting in impaired speech and movement. Fumes from the normal use
of this product contain manganese compounds. The TLV (Threshold Limit Value) for manganese exposure, 0.2
3
mg/m3, may be exceeded. Use enough ventilation, local exhaust and respirators to keep the workers鈥? breathing zone
and general area below the TLV for exposure to manganese.
Eye Protection: Arc Rays can injure your eyes. Wear helmet or face shield with filter lens of appropriate shade
number. See ANSI/ASC Z49.1 Section 4.2. Provide protective screens and flash goggles, if necessary, to shield
others.
Protective Clothing: Wear head and body protection, which help to prevent injury from radiation, sparks, flame and
electrical shock. See ANSI Z49.1. At a minimum this includes welder鈥檚 gloves and a protective face shield, and may
include arm protectors, aprons, hats, shoulder protection, as well as dark substantial clothing. Train the employee not
to touch live electrical parts and to insulate him/herself from work and ground. Welders should not wear short sleeve
shirts or short pants.
Section VIIII 鈥? Special Precautions and Information
OZONE DEPLETING SUBSTANCES- Products neither contain nor are manufactured with an ozone depleting
substance subject to the labeling requirements of the Clean Ai Act Amendments of 1990 and 40 CFR Part 82.
IMPORTANT- Maintain exposures below the TLV. Use industrial hygiene air monitoring to ensure that your use of
this material does not create exposures which exceed TLV. Always use exhaust ventilation. 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 (29CFR1910) US Government Printing Office, Washington, DC 20210.
Wash hands thoroughly after use, especially before eating, drinking or smoking.
