Explosive

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].

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Dilauroyl peroxide is an indirect food additive for use only as a component of adhesives.

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)|Flammable. Risk of fire and explosion on contact with combustible substances or reducing agents. Risk of fire and explosion on warming.

Excerpt from ERG Guide 145 [Organic Peroxides (Heat and Contamination Sensitive)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. LARGE SPILL: Consider initial evacuation for at least 250 meters (800 feet) in all directions. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 145 [Organic Peroxides (Heat and Contamination Sensitive)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Keep substance wet using water spray. Stop leak if you can do it without risk. SMALL SPILL: Pick up with inert, damp, non-combustible material using clean, non-sparking tools and place into loosely covered plastic containers for later disposal. LARGE SPILL: Wet down with water and dike for later disposal. Prevent entry into waterways, sewers, basements or confined areas. DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST. (ERG, 2016)

Protective gloves, goggles (USCG, 1999)|PROTECTIVE GLOVES, GOGGLES.|Wear long firm body-shield, and fully protective clothing. Preferably handle this material in a draft.|Persons handling peroxides should use safety glasses with side shields, goggles or face shield for eye protection. Emergency eyewash facilities should be provided. Gloves, aprons and other protective clothing as necessary should be used to prevent skin contact. Clothing and equipment that generate static electricity should be avoided. Smoking should be prohibited. /Peroxides, Organic and Inorganic/

WATER, DRY CHEMICAL, FOAM, OR CARBON DIOXIDE.|Combat fires from behind barrier. Flood discharge area with water. Cool exposed containers with water.|In case of fire, water should be applied by the sprinkler system or by hose from a safe distance, preferably with a fog nozzle. Foam may be necessary instead if the peroxide is diluted in a low density flammable solvent. Portable extinguishers should not be used except for very small fires. Peroxides threatened by fire should be wetted from a safe distance for cooling. /Peroxides, Organic and Inorganic/

Isolate and remove discharged material. Notify local health and pollution control agencies.|IN CASE OF SPILLS, SUPPLY OF INACTIVE ABSORBENT MATERIAL (EG VERMICULITE) SHOULD BE AVAILABLE. /PEROXIDES, ORG/|Spills should be cleaned up promptly using non-sparking tools and an inert, moist diluent such as vermiculite or sand. Sweepings may be placed in open containers or polyethylene bags and the area washed with water and detergent. Spilled, contaminated, waste or questionable peroxides should be destroyed. /Peroxides, Organic and Inorganic/|Most peroxides can be hydrolyzed by adding them slowly with stirring to about ten times their weight of cold 10% sodium hydroxide solution. The reaction may require several hours. /Peroxides, Organic and Inorganic/|Dilute and drain into the sewer with abundant water. /Hydrogen peroxide/

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

CONTACT WITH LIQUID IRRITATES EYES & SKIN. INGESTION CAUSES IRRITATION OF MOUTH AND STOMACH.

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.
