Organic peroxides are thermally unstable substances or mixtures, which can undergo exothermic self-accelerating decomposition. The thermal stability of an organic peroxide is characterized by its Self-Accelerating Decomposition Temperature (SADT). The SADT is the lowest temperature at which the peroxide will decompose in its original packaging via a so-called runaway reaction. This runaway reaction can be, dependent on the circumstances, a fierce decomposition, followed by self-ignition of the vapors or even an explosion.
Contamination of a peroxide with for instance metals, acid, alkalis or accelerators lowers the stability and consequently the SADT of the peroxide. This can possibly result in a runaway reaction at ambient temperatures. Especially MEKP formulations are very sensitive for contamination.

NOTIFY FIRE DEPARTMENT
SMALL FIRES - use water or carbon dioxide extinguisher.
LARGE FIRES - from a safe distance use water, preferably fog or spray or water-based agents such as AFF foam.
KEEP CONTAINERS COOL with water spray during fires near storage or handling areas.
DIFFICULT TO IGNITE – BURNS VIGOROUSLY, WITH INCREASED INTENSITY.
AFTER FIRE - WAIT UNTIL COOL before attempting clean-up or salvage operations.
EYES - Irrigate immediately with water and continue washing for at least 15 minutes. Obtain medical attention promptly.
SKIN - Remove contaminated clothes and shoes and then wash skin thoroughly with soap and water.
IF SWALLOWED - Do not induce vomiting. Drink large quantities of milk or water. Obtain immediate medical attention.
INHALATION - Obtain medical attention. Remove to fresh air and contact physician immediately.
STORE IN A COOL PLACE - AWAY FROM FLAMMABLE MATERIALS. Separate isolated storage should be provided for large quantities.
NEVER store in a REFRIGERATOR containing food or drink.
NEVER store with COBALT COMPOUNDS or other promoters or accelerators or corrosives or flammables.
ONLY ORIGINAL CONTAINERS should be used for storage.
"NO SMOKING" and "ORGANIC PEROXIDE" - "KEEP FIRES AWAY" signs should be provided at all storage locations.
