General Description
A white solid (shipped packed in Dry Ice to stabilize) with a sharp unpleasant odor. Insoluble in sater and sinks in water. Used as polymerization catalyst. (USCG, 1999)

Hazards

Reactivity Alerts
Air & Water Reactions
Highly flammable. Insoluble in water. Spontaneous decomposition at room temperature releases flammable toxic products.
Fire Hazard
Special Hazards of Combustion Products: Flammable and/or toxic gases formed in fires include acetone, isopropyl alcohol, acetaldehyde, and ethane.

Behavior in Fire: Undergoes auto- accelerative decomposition and may self-ignite. Confinement may lead to detonation. Fires very difficult to extinguish because air not needed (USCG, 1999)
Health Hazard
Inhalation overexposure unlikely, but prolonged exposure may cause lung edema. Contact with eyes may cause irritation. Solutions are severe primary skin irritants. (USCG, 1999)
Reactivity Profile
DIISOPROPYL PEROXYDICARBONATE decomposes violently or explosively at temperatures 0-10°C owing to self- accelerating exothermic decomposition; Several explosions were due to shock, heat, or friction; amines and certain metals can cause accelerated decomposition [Bretherick 1979 p. 156]. Spontaneous decomposition possible at room temperature to release flammable and corrosive products (presence of stabilizer reduces this possibility). A strong oxidizing agent. May ignite organic compounds on contact, hence a fire risk. Strongly reduced material such as sulfides, nitrides, and hydrides can react explosively. Reacts at least to produce heat when mixed with members of most chemical classes. These reactions often generate gases (toxic and nontoxic). Subject to decomposition, buildup of heat and even an explosion if contaminated with a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium or a salt of a transition metal).

Response Recommendations

Isolation and Evacuation
Excerpt from 148 Polymerizable warning [Organic Peroxides (Heat and Contamination Sensitive / Temperature Controlled)]:

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, 2020)
Firefighting
Fire Extinguishing Agents Not to Be Used: All extinguishing agents may be ineffective.

Fire Extinguishing Agents: Water (USCG, 1999)
Non-Fire Response
Excerpt from 148 Polymerizable warning [Organic Peroxides (Heat and Contamination Sensitive / Temperature Controlled)]:

DO NOT allow the substance to warm up. Use a coolant agent such as dry ice or ice (wear thermal protective gloves). If this is not possible or none can be obtained, evacuate the area immediately. ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch or walk through spilled material. 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: Dike far ahead of liquid spill 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, 2020)
Protective Clothing
Rubber gloves and shoes; hard hat; chemical splash goggles; plastic apron; respirator (depending on solvent used) (USCG, 1999)

First Aid
INHALATION: move to uncontaminated atmosphere; if breathing is difficult, give oxygen.

EYES: flush with copious amounts of water.

SKIN: wash off with isopropyl alcohol and water; call a physician. (USCG, 1999)
