Miscellaneous Organic Peroxides

Lauroyl peroxide is a mild eye irritant the irritation from 500 mg/day in rabbits eyes was mild. It is nontoxic. Prolonged exposure to laboratory animals caused tumors at the site of application. However, the evidence of carcinogenicity in animals is inadequate to date. 

Lauroyl peroxide presents a much smaller hazard than do most other diacyl peroxides. It is combustible in a dry state and shock sensitive only at elevated temperatures. Its self-accelerating decomposition temperature is 49°C (I20°F). 

It may ignite and explode when mixed with chemical accelerators, readily oxidiz-able, flammable, and organic compounds. Fire-extinguishing agent use a water spray from a safe location. 

Store in a well-ventilated, cool area, isolated from other chemicals. It is shipped in fiber drums not exceeding 100 lb. Small amounts may be shipped in 1-lb fiberboard boxes. 

Although lauroyl peroxide is relatively less hazardous, it is recommended that to handle spills and disposal, the same safety measures be followed as those for other hazardous organic peroxides.

The Department of Transportation (DOT) defines the term hazardous materials (or hazmat) as materials capable of posing an unreasonable risk to health, safety, and property, when transported in commerce. Each person who offers a material for transport must determine whether the material is hazardous. That is, the person must determine whether it is identified as an explosive, gas, flammable or combustible liquid, flammable solid, oxidizer or organic peroxide, poison, radioactive material, corrosive, or miscellaneous hazardous material. 

Transportation instmctions require DOT Hazard Class in which materials are divided into the following classes 1 - Explosives, 2 - Gases, 3 - Flammable and combustible liquids, 4 - Flammable spontaneously combustible solids, 5 - Oxidizers organic peroxides, 6 - Poisonous infectious materials, 7 - Radioactive materials, 8 - Corrosives, 9 - Miscellaneous. In addition UN number and packaging group is also given. 

There are nine classes of dangerous goods, with divisions of some classes. The classes are explosive flammable and non-flammable non-toxic gases flammable liquids flammable solids and spontaneously combustible materials oxidizing substances and organic peroxides toxic and infectious substances radioactive and fissile materials corrosive substances and miscellaneous.
