Quick details
UN 2017
Class: 6
Placard type: Toxic
ERG: Guide 159 (check current ERG)
Isolation: ERG 159: isolate spill or leak area immediately for at least 25-50 meters in all directions; if fire involved, isolate 800 meters and consider evacuation for 1600 meters downwind
Chemical & Response Details
| Also known as | CS tear gas ammunitionCN tear gas ammunitionLachrymatory agent ammunitionRiot control ammunitionTear gas cartridgesNon-lethal chemical ammunition |
| Appearance | Solid ammunition containing tear-producing agents (typically CS or CN compounds). CS is a white crystalline powder; CN is a pale yellow solid. Both produce irritating vapors when dispersed. |
| Flash Point | Not applicable (non-explosive ammunition) |
| Boiling Point | Not applicable (solid formulation, decomposes upon heating) |
| Vapor Density | Heavier than air when dispersed (particulates and vapors settle in low areas) |
| Water Reactivity | No significant reaction with water, though water may help disperse or wash away residues |
| Extinguishing | Not applicable for intact ammunition; if dispersed, use water spray to suppress vapors, avoid dry methods that spread particles |
| PPE | ⚠️ Full face respirator with organic vapor/particulate cartridges minimum; Level B with SCBA for enclosed spaces or heavy concentrations; eye protection essential |
| Isolation | ERG 159: isolate spill or leak area immediately for at least 25-50 meters in all directions; if fire involved, isolate 800 meters and consider evacuation for 1600 meters downwind |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Inhalation of vapors or dust is extremely irritating.
- May cause burning of eyes and lachrymation (flow of tears).
- May cause coughing, difficult breathing and nausea.
- Brief exposure effects last only a few minutes.
- Exposure in an enclosed area may be very harmful.
- Fire will produce irritating, corrosive and/or toxic gases.
- Runoff from fire control or dilution water may cause environmental contamination.
- Some of these materials may burn, but none ignite readily.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- Consider initial downwind evacuation for at least 100 meters (330 feet).
