Fire-fighting measures

Product-specific hazards and other issues :
Suitable extinguishing media
- SMALL FIRE: Use dry chemicals, CO2, water spray or alcohol-resistant foam
- LARGE FIRE: Use water spray, water fog or alcohol-resistant foam

Unsuitable Extinguishing Media Do not use solid water stream.

Fire may produce irritating, corrosive and/or toxic gases.:
- Vapor can burn in absence of air and may be flammable at either elevated temperature or
reduced pressure.
- Fine sprays/mists may be combustible at temperatures below normal flash point.
- Heat can cause exothermic decomposition.
- When evaporated, residual liquid will concentrate in TBHP content and may reach explosive
level (>90%).
- Run-off may create an explosion, fire, and environmental hazard.
- Burning material may release gases, rupture closed containers, spreading fire, increasing risk of
burns/injuries. Availability of other combustibles may hasten burning, spreading fire.
- Flood fire area with water form a distance.
- Do not use straight streams.
- Move containers from fire area if you can do it without risk.
- Do not move cargo or vehicle if cargo has been exposed to heat.
- Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
- Use water spray/fog for cooling.
- Always stay away from tanks engulfed in fire.
- For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw
from area and let fire burn.
- Notify authorities immediately if liquid enters sewer/public waters.

Handling and storage

Handling

Product-specific hazards and other issues
General information :
Advice on safe handling
- For industrial use only.
- Closed containers may generate internal gas pressure by decomposition (oxygen) which can
accelerate burning of combustibles.
- Overpressure may rupture container/cause serious injury/result in or accelerate fire.
- Provide nitrogen pad to dilute any free oxygen buildup and prevent any hydroperoxide self-
combustion.
- Use only non-sparking tools.
- Properly ground containers before beginning transfer.
- All equipment must conform to applicable electrical code.
- Minimize formation of sprays during transfer.
- Inspect frequently to identify bulging or leaking containers.
- Isolate/depressure if safe to do so.
- Do not steam purge systems containing this material until they have been properly flushed with
a suitable material such as mineral oil, kerosene, TBA, etc - depending on system compatibility.
Isolate, vent, drain, wash and purge systems or equipment before maintenance or repair.
- Extinguish all ignition sources.
- Check atmosphere for explosiveness and oxygen deficiencies.
- Wear recommended personal protective equipment.
- Observe precautions pertaining to confined space entry.

Advice on protection against fire and explosion
- Avoid formation of aerosol.
- Keep away from sources of ignition - No smoking.
- Take measures to prevent the build up of electrostatic charge.
- Keep away from combustible material.

Storage

Requirements for storage areas and containers : - Keep away from open flames, hot surfaces and sources of ignition.
