Reactivity Alerts
Air & Water Reactions
No rapid reaction with air. No rapid reaction with water.
Fire Hazard
Excerpt from 114 Polymerizable warning [Explosives* - Division 1.4 or 1.6]:

MAY EXPLODE AND THROW FRAGMENTS 800 METERS (1/2 MILE) OR MORE IF FIRE REACHES CARGO. For information on "Compatibility Group" letters, refer to Glossary section. (ERG, 2020)
Health Hazard
Excerpt from 114 Polymerizable warning [Explosives* - Division 1.4 or 1.6]:

Fire may produce irritating, corrosive and/or toxic gases. (ERG, 2020)
Reactivity Profile
The organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with a strong oxidizing acid. The unsubstituted tetrazole is unstable when heated above its melting point. Its solutions are also explosive when shocked. Carbonyl azides are explosive, some exceptionally so, and suitable handling is necessary, Leiber, E. et al., Chem. Rev., 1965, 65, 377.

Response Recommendations

Isolation and Evacuation
Excerpt from 114 Polymerizable warning [Explosives* - Division 1.4 or 1.6]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area immediately for at least 100 meters (330 feet) in all directions.

LARGE SPILL: Consider initial evacuation for 250 meters (800 feet) in all directions.

FIRE: If rail car or trailer is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also initiate evacuation including emergency responders for 800 meters (1/2 mile) in all directions. If fire threatens cargo area containing packages bearing the 1.4S label or packages containing material classified as 1.4S, consider isolating at least 15 meters (50 feet) in all directions. (ERG, 2020)
Firefighting
Excerpt from 114 Polymerizable warning [Explosives* - Division 1.4 or 1.6]:

CARGO FIRE: DO NOT fight fire when fire reaches cargo! Cargo may EXPLODE! Stop all traffic and clear the area for at least 800 meters (1/2 mile) in all directions and let burn. Do not move cargo or vehicle if cargo has been exposed to heat.

TIRE OR VEHICLE FIRE: Use plenty of water - FLOOD it! If water is not available, use CO2, dry chemical or dirt. If possible, and WITHOUT RISK, use unmanned master stream devices or monitor nozzles from maximum distance to prevent fire from spreading to cargo area. Pay special attention to tire fires as re-ignition may occur. Stand by, at a safe distance, with extinguisher ready for possible re-ignition. CLASS 1.4S Fire Packages bearing the 1.4S label or packages containing material classified as 1.4S are designed or packaged in such a manner that when involved in a fire, they may burn vigorously with localized detonations and projection of fragments. Effects are usually confined to immediate vicinity of packages. Fight fire with normal precautions from a reasonable distance. (ERG, 2020)
Non-Fire Response
Excerpt from 114 Polymerizable warning [Explosives* - Division 1.4 or 1.6]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. DO NOT OPERATE RADIO TRANSMITTERS WITHIN 100 METERS (330 FEET) OF ELECTRIC DETONATORS. DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST. (ERG, 2020)
Protective Clothing
Excerpt from ERG Guide 114 [Explosives* - Division 1.4 or 1.6]:

Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. (ERG, 2020)

First Aid
Excerpt from 114 Polymerizable warning [Explosives* - Division 1.4 or 1.6]:

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. (ERG, 2020)
