Reactivity Alerts
Air & Water Reactions
Dust may form an explosive mixture in air. Insoluble in water.
Fire Hazard
Excerpt from 150 Polymerizable warning [Substances (Self-Reactive / Temperature Controlled)]:

Self-decomposition, self-polymerization, or self-ignition may be triggered by heat, chemical reaction, friction or impact. Self-accelerating decomposition may occur if the specific control temperature is not maintained. These materials are particularly sensitive to temperature rises. Above a given "Control Temperature" they decompose or polymerize violently and may catch fire. May be ignited by heat, sparks or flames. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Some may decompose explosively when heated or involved in a fire. May burn violently. Decomposition or polymerization may be self-accelerating and produce large amounts of gases. Vapors or dust may form explosive mixtures with air. (ERG, 2020)
Health Hazard
Excerpt from 150 Polymerizable warning [Substances (Self-Reactive / Temperature Controlled)]:

Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce irritating, toxic and/or corrosive gases. Runoff from fire control or dilution water may cause environmental contamination. (ERG, 2020)
Reactivity Profile
4-DIMETHYLAMINO-6-(2-DIMETHYLAMINOETHOXY)TOLUENE-2-DIAZONIUM ZINC CHLORIDE is a diazonium salt, a class of compounds which can be shock-sensitive and decompose violently with heating. Because they are so unstable, they are usually not isolated, but are instead used as intermediates for organic syntheses. Many diazonium salts are susceptible to displacement reactions by various substrates, generating nitrogen gas (N2) as a by-product. Another common reaction pathway is to undergo a coupling reaction to form a diazo compound. Diazonium salts in general are high energy materials that can decompose violently either by heating or by mechanical force (shock-sensitive), so in that sense, they may be considered self-reactive. Stability often is improved by adding zinc chloride or other salts. Conversely, exposure to bases, transition metal impurities (e.g. Cu, Sn), nitrous acid and/or direct sunlight can promote decomposition and lower the onset temperature of decomposition. Diazonium salts should never be heated above 40°C and the dried powder should not be "scratched" with a metal spatula or ground finely, as this friction could be enough to cause an explosive decomposition (H. Zollinger, Diazotization of amines and dediazoniation of diazonium ions. In S. Patai, The Chemistry of Amino, Nitroso, Nitro and Related Groups, John Wiley & Sons, Ltd. (1996), 627).

Response Recommendations

Isolation and Evacuation
Excerpt from 150 Polymerizable warning [Substances (Self-Reactive / 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
Excerpt from 150 Polymerizable warning [Substances (Self-Reactive / Temperature Controlled)]:

The temperature of the substance must be maintained at or below the "Control Temperature" at all times.

SMALL FIRE: Dry chemical, CO2, water spray or regular foam.

LARGE FIRE: Flood fire area with water from a distance. If it can be done safely, move undamaged containers away from the area around the fire.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: BEWARE OF POSSIBLE CONTAINER EXPLOSION. Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2020)
Non-Fire Response
Excerpt from 150 Polymerizable warning [Substances (Self-Reactive / 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. 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. 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
Excerpt from ERG Guide 150 [Substances (Self-Reactive / Temperature Controlled)]:

Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE. Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. (ERG, 2020)

First Aid
Excerpt from 150 Polymerizable warning [Substances (Self-Reactive / Temperature Controlled)]:

Call 911 or emergency medical service. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air if it can be done safely. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Keep victim calm and warm.
