What is the primary precaution when using glycol on a fire?

1. Use to extinguish electrical fires

2. Only use after fire is out

3. Never use on electrical fires

4. Use for all types of fires

The correct answer is: Never use on electrical fires

The primary precaution when using glycol on a fire is that it must never be used on electrical fires. Glycol can act as a conductor of electricity, posing a significant risk of electrocution if used on an active electrical fire. This precaution is critical because using an inappropriate substance can exacerbate the situation, leading to further hazards instead of effectively extinguishing the flames. When managing fires, it’s essential to understand the specific fire type and the recommended extinguishing agents for each. Electrical fires, for example, usually require non-conductive agents such as carbon dioxide or dry chemical extinguishers to ensure safety. Other options outlined may suggest alternatives or approaches that do not adequately support safety protocols surrounding electrical fires.
