Quick Answer

For energized electrical equipment, use an extinguisher appropriate for Class C electrical hazards. Around sensitive electronics or expensive equipment, a clean-agent extinguisher can be a strong choice because it leaves no dry chemical powder behind—reducing cleanup, contamination, and potential corrosion concerns.

Dry Chemical vs. STOP-FYRE®

Both can be used for appropriate electrical hazards, but what happens after discharge can be very different—especially when valuable electronics and equipment are involved.

Frequently Asked Questions

What class of fire is an electrical fire?

Fires involving energized electrical equipment are treated as Class C hazards. The extinguisher should be appropriate for both the electrical hazard and the material that may be burning.

Can dry chemical powder damage electronics?

Dry chemical powder can spread into electronics, controls, cabinets, wiring, and other components, creating additional cleanup after the fire has been extinguished.

Can dry chemical extinguisher powder cause corrosion?

Multipurpose dry chemical residue may contribute to corrosion under certain heat and humidity conditions, especially when residue remains on equipment.

Is a clean-agent extinguisher good for electronics?

Clean-agent extinguishers are often considered around sensitive equipment because they can suppress fire without leaving dry chemical powder behind. Always confirm the extinguisher is appropriate for the specific hazard.

Trusted Resources

Workplace note: Where OSHA 29 CFR 1910.157 applies, required workplace extinguishers must meet applicable approval requirements. STOP-FYRE® can provide supplemental clean-agent protection where a separately approved extinguisher is required.
