The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.
Reactivity Alerts
  • Highly Flammable
  • Explosive
  • Strong Oxidizing Agent
  • Decomposes at Elevated Temperatures (<120 deg. C)
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).
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources.
Isolation and Evacuation
Excerpt from ERG Guide 148 [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 tank car or highway tank 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, 2024)
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 ERG Guide 148 [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, 2024)
Protective Clothing
Rubber gloves and shoes; hard hat; chemical splash goggles; plastic apron; respirator (depending on solvent used) (USCG, 1999)
DuPont Tychem® Suit Fabrics
No information available.
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)

The Physical Property fields include properties such as vapor pressure and boiling point, as well as explosive limits and toxic exposure thresholds The information in CAMEO Chemicals comes from a variety of data sources.

Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
