UN 2994 — Arsenical pesticide, liquid, poisonous
Placard: Toxic. ERG Guide 151. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Arsenical pesticide, liquid, poisonous is a broad pesticide formulation entry. Treat it as a toxic liquid and use the label, SDS and shipping papers to identify the active ingredient, solvent and response limits.
Hazard overview: The main hazards are toxic exposure and contaminated runoff. Fire behavior depends on the formulation and carrier solvent. Do not rely on the UN name alone for medical or cleanup decisions.
Response guidance: Isolate the area, avoid skin contact, stop the leak only if safe and contain all runoff. Use dry chemical, CO2, foam or water spray for surrounding fire based on the SDS.
Firefighter training notes: Train responders to identify UN 2994 from shipping papers, confirm the SDS, choose PPE from monitoring results and avoid relying on generic placard information alone.
Regulatory context: UN 2994 is listed for transport under hazard class 6 with ERG Guide 151. Confirm packing group, quantity limits and any special provisions from current DOT/TDG/IMDG documents.
Storage & handling: Store only in approved, labeled containers or packaging. Keep incompatible materials separated, control ignition sources where applicable and protect packages from heat, damage and unauthorized access.
UN 2994 Quick Details
Common Hazards of UN 2994
- Broad arsenical pesticide liquid entry; active ingredient and solvent carrier must be confirmed from SDS and labels.
- Product may be nonflammable or combustible depending on the carrier; do not assume low fire risk without SDS.
- May be fatal or seriously harmful if inhaled, swallowed or absorbed through skin.
- Liquid or mist can irritate or burn skin, eyes and respiratory tract.
- Fire may produce toxic, corrosive or irritating decomposition products.
- Spill runoff can contaminate soil, drains and waterways.
- Vapors or aerosols may collect in low or confined areas depending on the solvent system.
- Containers may rupture when heated.
Chemical Identity & Physical Properties
Liquid pesticide formulation containing arsenic compounds. Color and odor vary depending on formulation and additives; may be clear to colored liquid with characteristic pesticide odor.

| Appearance | Liquid pesticide formulation containing arsenic compounds. Color and odor vary depending on formulation and additives; may be clear to colored liquid with characteristic pesticide odor. |
| Flash Point | Varies by formulation and carrier solvent; typically 23C to 61C (73F to 142F) for common petroleum-based carriers |
| Boiling Point | Varies by formulation and carrier solvent; typically 100C to 200C (212F to 392F) |
| Vapor Density | Greater than 1 (heavier than air); specific value depends on carrier solvent |
| Water Reactivity | No significant reaction with water, though arsenic compounds may dissolve or disperse |

PPE Requirements
SCBA and chemical-resistant clothing are required for releases. Use Level A for unknown/high vapor conditions; Level B may be used when monitoring confirms lower risk.
Isolation & Evacuation
First Actions for a UN 2994 Incident
- Call 911 and the emergency response number listed on the shipping papers.
- Keep unauthorized personnel away and establish hot, warm and cold zones.
- Stay upwind, uphill and upstream; avoid low areas where vapors may collect.
- Avoid breathing vapors, fumes, dust or spray mist; prevent skin and eye contact.
- Do not touch damaged packages or containers without appropriate PPE and monitoring.
- Ventilate confined spaces only when personnel are trained, equipped and monitored.
- Use the ERG guide, SDS, shipping papers and product labels to confirm final tactics.
