2 Composition / Data on Components
Description
CADWELD Electrical Welding Materials are exothermic mixtures that react to produce molten metal and a ceramic
phase by-product. The reaction temperatures can exceed 4000潞F (2200潞C ) producing molten metal in excess of
2500潞F (1370潞C). These products are intended for use with CADWELD accessories only in making permanent
connections.

3 Hazard Identification
Hazard Description
Improper use of the product or inadequate preparation of the conductors, molds or surroundings can result in
aggressive reactions. Instruction prints should be followed at all times. If information is missing contact ERICO or
visit our web site at www.erico.com to obtain proper procedures.
Self-propagating high temperature reaction will occur if heated above ignition temperature. Generates molten metal
in excess of 2500潞F (1370潞C), slag, and dense, dusty smoke.
Immediate Hazards
Burns from contact with reaction, reaction products, or from hot equipment are possible.
Exposure To Reaction By-Products
A detailed fume analysis was conducted on CADWELD Electrical Welding Materials. Reactions byproducts were
tested for total dust, respirable dust, metals, acids, fluorides, and various elements identified in typical welding
fume analysis. All sampling and analysis followed methodologies dictated by the National Institute of
Occupational Safety and Health (NIOSH) and by the Occupational Safety and Health Administration (OSHA). A
certified Industrial Hygienist did the sample collection and independent labs conducted all analytical work.
Data collected was evaluated and compared to limits set by the American Conference of Governmental Industrial
Hygienists (ACGIH) and OSHA. As a worse case scenario, calculations were completed based on a sealed 800 ft 3
room with no ventilation. These calculations would indicate that the copper fume PEL would be the limiting factor.
Under normal outdoor use or in ventilated areas threshold limits are beyond any expected exposure limits.

CADWELD 庐 Electrical Welding Material
4 First Aid Measures
General Information
The product produces materials at elevated temperatures. Proper protection should be utilized to avoid contact
with hot materials. Standard treatment for burns in the event of contact with molten metal, slag or hot equipment
Inhalation
For excessive inhalation of dust, fume, remove from exposure, provide fresh air, and consult a physician.
Skin contact
Standard treatment for burns in the event of contact with molten metal, slag or hot equipment.
Eye contact
Exposure to powdered metals should be treated by flushing eyes with large amounts of water from the nasal area
outward. Consult a physician if irritation persists.
Eye contact with molten metal or reaction by products requires immediate medical attention.
5 Fire Fighting Measures
Suitable Extinguishing Agents
Dry sand and/or flooding with large amounts of water. Water application should be at a reasonable distance. Use
of hand water buckets or hand storage pumps is not recommended. Molten metal contact with water can cause
small pockets of superheated steam.
Suitable extinguishing agents should be used to protect surrounding areas.
Additional Information
CADWELD Electrical Welding Materials are exothermic mixtures, which react to produce hot molten metals with
temperatures in excess of 2500潞F (1370潞C) and small amounts of metal fume and smoke. Ignition temperatures are in
excess of 1750潞F (950潞C). The material is not sensitive to vibrations, shock, or impact and is not subject to any form
of spontaneous ignition.
In the event that the packaging materials are ignited, the immediate and direct application of large quantities of
water will effectively eliminate the spread of fire to the surrounding areas. The ignition of the packaging materials
may, in rare cases, lead to ignition. Direct application of a continuous heavy stream of water is recommended.
Ignition of extremely large quantities of exothermic materials may result in large volumes of dense smoke.

6 Accidental Release Measures
Person-Related Safety Precautions
RESPIRATORY PROTECTION: Normal use precludes use of special protection as material is generally used out of
doors, in small quantities and is of short duration.
VENTILATION: Local Exhaust - May be necessary if used in confined space. Special - Use of NIOSH approved
respirator for dusts and metal fumes in lieu of local exhaust.
PROTECTIVE GLOVES: Recommended for handling hot equipment.
EYE PROTECTION: Safety glasses recommended and caution to user to avoid direct eye contact with "flash" of
light from reaction.
Measures for Environmental Protection
Precautions should be taken to prevent hot material and reaction byproducts from contact with combustible
materials in surrounding areas.
Measures for Cleaning/Collecting
All unused, spilled materials may be swept up for disposal, in accordance with local regulations and guidelines.
7 Handling and Storage
Handling
CADWELD Exothermic Welding Materials are designed for use in CADWELD equipment only. Use of improper or
damaged equipment can lead to exposure to molten metal and reaction byproducts, resulting in personal injury.
All product instructions should be followed to help ensure proper welding and safety. For additional information,
see American National Standard, Safety In Welding And Cutting, Z49.1.
Storage
CADWELD Electrical Welding Material should be stored in a clean, dry and secure location. Storage should
include provisions to minimize rough handling, excessive vibration and physical abuse. All outer packages must
be stored in accordance with label markings.
If proper storage is maintained, CADWELD Electrical Welding Materials do not exhibit any storage or shelf life.
If evidence is present of damaged or contaminated products, these units should not be used.
