Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Contact with liquid irritates eyes and skin. Ingestion causes irritation of mouth and stomach. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Treatment: prompt washing of affected areas is essential.
SECTION 5: Firefighting measures
Suitable extinguishing media
Water, dry chemical, foam, or carbon dioxide.
Specific hazards arising from the chemical
Behavior in Fire: Can increase the severity of a fire. Becomes sensitive to shock when hot. Containers may explode in a fire. May ignite or explode spontaneously if mixed with flammable materials. (USCG, 1999)
Special protective actions for fire-fighters
Use water in large amounts, water spray. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Consult an expert! Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Remove all ignition sources. Do NOT absorb in saw-dust or other combustible absorbents. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Methods and materials for containment and cleaning up
Isolate and remove discharged material. Notify local health and pollution control agencies.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Prevent warming above 25°C. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof. Separated from combustible substances and reducing agents. Cool.Store in a cool, well-ventilated storage of noncombustible construction, distant from residences. Separate from other stocks, especially vulcanizing agents, easily oxidizable organic materials, and combustible material; avoid fire and sparks. Provide large-quantity storage room with cool sprinkler system. Protect containers against physical damage. Do not open containers in storage room. Do not place in glass-stopper or screw-capped containers because of possible explosion caused by frictional handling.

SECTION 10: Stability and reactivity
Reactivity
Heating may cause violent combustion or explosion. The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard.
Chemical stability
Stable if not overheated
Possibility of hazardous reactions
FIRE HAZARD: ORGANIC PEROXIDES CONTAIN SUFFICIENT AVAILABLE OXYGEN TO SUPPORT THEIR OWN COMBUSTION EVEN IN A DEFICIENCY OR ABSENCE OF ATMOSPHERIC OXYGEN. /PEROXIDES, ORGANIC/LAUROYL PEROXIDE is an oxidizing agent. Can ignite organic materials; hence a dangerous fire and explosion risk [Hawley]. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively. Vigorous reactions with other reducing agents. With charcoal sometimes ignites. [Bretherick, 5th ed., 1995, p. 1194].
Conditions to avoid
no data available
Incompatible materials
Dangerous fire & explosion risk; will ignite organic materials.
Hazardous decomposition products
Becomes shock sensitive on heating, and self-accelerating decomposition sets in at 49 deg C.

Carcinogenicity
Evaluation: No epidemiological data relevant to the carcinogenicity of lauroyl peroxide were available.

Overall evaluation: Lauroyl peroxide is not classifiable as to its carciogenicity to humans (Group 3).
Reproductive toxicity
no data available
STOT-single exposure
The aerosol is irritating to the eyes, skin and respiratory tract.
STOT-repeated exposure
no data available
Aspiration hazard
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
