IMPORTANT DATA

Physical State; Appearance
COLOURLESS LIQUID, WITH PUNGENT ODOUR.

Chemical dangers
Heating may cause violent combustion or explosion. On combustion, forms toxic and corrosive gases. The substance is a strong oxidant and reacts violently with combustible and reducing materials amines, metals, strong acids, strong bases,, causing fire and explosion hazard.

Occupational exposure limits
TLV: 0.2 ppm (Ceiling value) (ACGIH 2005).
MAK not established.

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of short-term exposure
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point (decomposes): >80°C Relative density (water = 1): 1.10-1.17 Solubility in water: very poor

NOTES

The occupational exposure limit value should not be exceeded during any part of the working exposure.
Technical product is sold with 40-60% of diluent (for example, dimethyl phthalate, cyclohexanol peroxide, diallyl phthalate) to reduce potential explosion hazard.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Rinse contaminated clothes (fire hazard) with plenty of water.
Other UN numbers 3105, 3107 for Organic peroxide.
