Quick details
UN 0238
Class: 1
Placard type: Explosive 1.3G
ERG: Guide 112 (check current ERG)
Isolation: ERG 112: Initial isolation 500m in all directions; if fire involves rockets, evacuate 1600m radius; protect from fire, shock, and static discharge
Chemical & Response Details
| Also known as | Line-throwing rocketsDistress signal rocketsMarine line-throwing apparatusShip-to-ship line rockets |
| Appearance | Solid propellant rockets in cylindrical metal or composite casings, typically red or orange colored, designed to carry a line for rescue or mooring operations. Contains explosive propellant and may include pyrotechnic illuminating or signaling components. |
| Flash Point | Not applicable (explosive solid with self-contained oxidizer) |
| Boiling Point | Not applicable (solid explosive composition) |
| Vapor Density | Not applicable (solid article) |
| Water Reactivity | Generally stable in water, but moisture can degrade propellant over time; do not use water to extinguish burning rockets |
| Extinguishing | Do not use foam or water; use dry chemical, sand, or earth to smother small fires; allow larger fires to burn unless threatening structures |
| PPE | ⚠️ Level B minimum with structural firefighting gear; SCBA required; maintain blast-resistant cover; fragment projection risk up to 300m |
| Isolation | ERG 112: Initial isolation 500m in all directions; if fire involves rockets, evacuate 1600m radius; protect from fire, shock, and static discharge |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Fire and burning hazard — not mass explosion.
- Intense heat and possible fragment projection.
- May deflagrate and initiate other materials.
- Smoke and toxic combustion products.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper.
- Isolate area; stage upwind — fire and fragment hazard.
- Request Hazmat + law enforcement.
- Control ignition sources; deny entry.
- Consult current ERG Guide 112 and follow SOP/SOG.
