SECTION 5 FIRE FIGHTING MEASURES
GENERAL HAZARDS
The materials are not explosive; ignition temperatures are in excess of 850°F (454°C) for starting material
and 1750° F (954°C) for base material. They are not shock sensitive, nor are they subject to spontaneous
ignition. Should the material be accidentally ignited, the immediate and direct application of large volumes
of water will effectively retard the spread of fire and control it. Large amounts of dense, dusty smoke will be
liberated during an accidental fire. Smoke, oxides of carbon; fumes of copper and aluminum, small amounts
of fluoride fume or hydrofluoric acid fume may be released under ignition.
EXTINGUISHING MEDIA
Appropriate Extinguishing Media: Use carbon dioxide, water, water fog, dry chemical, chemical foam,
dry sand.
Inappropriate Extinguishing Media: None known
FIRE FIGHTING PROCEDURES
Fire Fighting Instructions: Firefighters must wear full face piece self- contained breathing apparatus in
positive pressure mode. Water may be used from a distance once reaction is complete. Molten metal
contact with water can produce pockets of superheated steam.
Unusual Fire Hazards / Combustion Products: BURNDY Weld copper base welding/joining materials are
exothermic mixtures, which when reacted, produce hot molten materials with temperatures in excess of
4000° F (2204° C) and a localized release of smoke.
SECTION 6 ACCIDENTAL RELEASE MEASURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:
Confine and segregate product for reuse; place material into approved containers for disposal; for spills in
excess of allowable limits (RQ) notify the National Response Center (800) 424 - 8802; refer to CERCLA 40
CFR 302 for detailed instructions; refer to SARA Title Ill, Section 313, 40 CFR 372 for reporting requirements.
Do not discharge into lakes, ponds, streams or public waters.
ENVIRONMENTAL PRECAUTIONS:
Copper and Aluminum can be serious marine pollutants. Prevent entry into waterways, sewer, basements or
confined areas. In the event of a spill or accidental release, notify relevant authorities in accordance with all
applicable regulations. The National Response Center can be reached at [phone]; refer to CERCLA
40 CFR 302 for detailed instructions; refer to SARA Title Ill, Section 313, 40 CFR 372 for reporting
requirements.
CLEAN UP AND CONTAINMENT METHODS:
Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Stop leak if you can
do it without putting yourself in harm's way. All equipment used when handling the product must be
grounded. Avoid breathing vapors/fumes/dusts and wear specific protective equipment specified in section 8.
Use clean non-sparking tools to collect material and segregate material for reuse. If material cannot be
reused place material in appropriate disposal container.
Spill recommendations are based on the most likely spill scenario for this material; however, geographic
conditions, wind, temperature, (and in the case of a water spill) wave and current direction and speed may
greatly influence the appropriate action to be taken. For this reason, local experts should be consulted.
Note: Local regulations may prescribe or limit action to be taken.
SECTION 7 HANDLING AND STORAGE
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE:
Storage of BURNDYWeld Exothermic materials should be in a clean dry area and restricted to access by
authorized personnel only.
Do not subject to rough handling or physical damage, nor excessive vibration. Store in accordance with "This
Side Up" labels. Protect from weather and moisture. DO NOT USE PRODUCTS THAT HAVE BEEN
