For metal fires: Use specific agents only.

Infrared radiation from flame or hot metal can ignite combustibles and flammable products. When involved in a fire, these products may generate irritating fumes and a variety of metal compounds. The molten material can present a significant thermal hazard to firefighters.

Use standard firefighting procedures and consider the hazards of other involved materials.

Prevent waste from contaminating surrounding environment.

Avoid breathing dust. Ensure exhaust system at the workplace. Any deposit of dust which cannot be avoided must be regularly removed. Read and understand the manufacturer's instruction and the precautionary label on the product. Refer to Lincoln Safety Publications at www.lincalelectric.com/safety. See the Australian Standard - AS 1674.1 - 1997 - Reconfirmed 2016. Safety in Welding and Allied Processes Australia.

Store in closed original container in a dry place. Store away from incompatible materials. Store in accordance with local/regional/national regulations.

No special measures required.

Use enough ventilation, local exhaust at the flame or heat source, or both to keep the fumes and gases from the worker's breathing zone and the general area. Train the operator to keep his head out of the fumes. Keep exposure as low as possible.

Thermally-protective gloves. Suitable gloves can be recommended by the glove supplier. The glove material has to be impermeable and resistant to the product/ the substance/ the preparation.

Wear helmet, glasses or face shield with filter lens protective screens, flash goggles to shield others. Start with shade too dark then go to lighter shade which gives sufficient view of weld zone.

Use respirable fume respiratory or air supplied respirator when in confined space or local exhaust does not keep exposure below recommended exposure limit. An approved respirator should be used unless exposure assessments are below applicable exposure limits. Particulate mask should filter at least 99% of airborne particles. For maximum safety: Be certified for and wear a respirator at all times when welding and brazing.

Protective work clothing

No special requirements.

Stable under normal temperatures and pressures.

the composition and quality of welding fumes and gases are dependent upon the metal being welded, the process, procedure and electrodes used. other conditions which also influence the composition and quantity of fumes and gases to which workers may be exposed include: coatings on metal being welded (such as paint, plating, or galvanizing), the number of welders and volume of the work area, the quality and amount of ventilation, the position of welder's head with respect to fume plume, and the presence of contaminants in atmosphere (chlorinated hydro-carbon vapors from cleaning and degreasing activities). when electrode is consumed, the fume and gas decomposition products generated are different in percent and form from ingredients in section 2. fume and gas decomposition products, and not ingredients in electrode, are important. Concentration of given fume or gas component may decrease or increase by many times original concentration. new compounds in electrode may form. decomposition products of normal operation include those originating from volatilization, reaction, or oxidation of materials in section 2, plus those from base metal and coating, etc., as noted above. reasonably expected fume constituents of product could include primarily oxides of iron; secondarily oxides of chromium, nickel, manganese, silicon, and molybdenum. present osha EXP. LIMITS FOR HEXAVALENT-CHROMIUM (0.05 mg/m3 and nickel 1mg/m3 which will result in significant reduction from 5mg/m3 general fume level. gaseous reaction in products may include carbon monoxide and carbon dioxide. ozone and nitrogen oxides may be formed by the radiation from arc, in addition to shielding gases like argon and helium when employed. one recommended way to determine composition and quantity of fumes and gases to take air sample from inside welder's helmet if worn or in breathing zone. see AWS R.1 and AWS R.2 - 1985, available from the American welding society. see aws publication: "fumes and gases in the welding environment".

None unless otherwise specified.

No further relevant information available.

Brazing fumes and gases cannot be classified simply. The composition and products: quantity of both are dependent upon the metal being joined, the process, procedure and filler metals and flux 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 joined (such as paint, plating, or galvanizing), the number of operators and the volume of the worker area, the quality and amount of ventilation, the position of the operator's head with respect to the fume and fumes from chemical fluxes used in some brazing operations.
