ERICO CADWELD for Rebar Splicing System - Manual (Page 2)

IMPORTANT
General and Safety Information
A. Only ERICO ® manufactured equipment and materials should be used to make CADWELD ® rebar splices.
1. Do not splice except as detailed in the instructions.
2. Do not use worn or broken equipment that could cause leakage.
3. Do not alter equipment or material without factory authorization.
4. Do not substitue for specified ERICO manufactured equipment and materials.
Failure to comply with the above may result in hazards to the individual, improper splices, or damage to items being spliced.
B. Make splices in accordance with described splicing procedures and in consideration of surrounding conditions and personnel.
Refer to ANSI Z-49.1 SAFETY IN WELDING AND CUTTING and your local safety procedures.
1. Personnel should be properly trained in the use of this product.
2. Avoid breathing concentrations of smoke, as it may be hazardous to health.
3. Avoid contact with hot materials.
4. Advise nearby personnel of splicing operation in the area.
5. Remove or protect fire hazards in the immediate area.
6. Do not smoke when handling starting material.
C. Adhering to the recommended splicing procedures will minimize risk of burns and fire caused by hot molten material
spillage.
1. Make sure there is proper fit and assembly of equipment.
2. Avoid moisture and decomposable contaminants on splicing equipment and rebar.
Contact of hot molten metal with moisture or contaminants may result in spewing of hot material.
D. Unusual applications or conditions may exist which require special considerations.
1. Provide adequate ventilation where natural air flow is not sufficient to prevent personnel breathing concentrations of
smoke.
E. Storage of CADWELD filler material should be in a clean, dry, “No Smoking” area and should be restricted to access by
authorized personnel only.
1. Starting material and filler material are exothermic mixtures and react to produce hot molten materials with
temperatures in excess of 2200°C (4000°F) and a localized release of smoke. These materials are NOT explosive.
Ignition temperatures are in excess of 450°C (850°F) for starting material and 900°C (1650°F) for filler material.
2. In case of fire, water or CO

will aid in control of burning containers. Large quantities of water will aid in controlling
a fire should the exothermic materials become involved. Water should be applied from a distance.
F. CADWELD filler material in the work area should be protected from spatter and hot materials to prevent accidental ignition.
Use a covered wood or metal gang box for storage of materials not for immediate use.
G. Dispose of slag from the CADWELD splicing process in a steel container that has a layer of dry sand in the bottom.
The sand is necessary to prevent burn through.
H. See splicing instructions enclosed for additional information.
