CAUTION
⚠
Use extreme care when opening, pouring, and mixing
flammable antifreeze solutions. Remote flames or
electrical sparks can ignite undiluted antifreezes and
vapors. Use only in a well ventilated area. Do not smoke
when handling flammable solutions. Failure to observe
safety precautions may result in fire, injury, or death.
Never work with 100% alcohol solutions.
Notes:
1.
Consult with your representative or distributor if you have any questions regarding antifreeze selection or use.
2.
Some antifreeze suppliers and manufacturers recommend the use of either de-ionized or distilled water with their products.
Some brands are designed to work with tap water. Consult the antifreeze manufacturer’s technical data.
