First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Move the affected person away from the contaminated area and into the fresh air. Give artificial respiration if necessary. Call a doctor.

Symptoms: Headache. Nausea.

Skin contact

Immediately remove contaminated clothing or footwear. Rinse with plenty of water. Call a physician immediately.

Symptoms: May cause moderate irritation. Redness. Exposure may produce an allergic reaction.

Eye contact

Rinse immediately and thoroughly, pulling the eyelids well away from the eye (15 minutes minimum). If irritation persists, consult an eye specialist.

Symptoms: Eye irritation. Redness.

Ingestion

Rinse mouth out with water. Never attempt to induce vomiting. Call a physician Immediately.

Symptoms: Nausea. Headache. Symptoms of vasodilation may occur following organic nitrate over exposure

Medical Treatment

Treat as organic nitrate poisoning.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Carbon dioxide (CO2). Water spray. Foam. Dry powder.

Specific hazards

2-EHN is thermally unstable - when heated above 100°C, it may undergo a self-accelerating exothermic decomposition. Upper tank surfaces in contact with the vapour will rapidly reach the auto-ignition temperature (130°C) of 2-EHN. This will lead to an air-vapour explosion in the headspace of the tank. Sealed drums of 2-EHN in an intense fire will rupture. Bursting drums will give rise to projectiles/flying fragments and fireball formation.

Instructions

Removal of radiant heat from nearby fire is vital. Apply deluge water onto tank walls to keep the product cool. Cool containers exposed to flames with flooding quantities of water until well after the fire is out. Fight any fire from a safe distance or protected locations. Do not approach containers suspected to be hot, if tank, rail car or tank truck is involved in fire, ISOLATE the container and evacuate personnel to ensure safety. Drums and IBC's should be immediately cooled by spraying firewater from a fixed deluge.

Firefighter Protection

Do not attempt to take action without suitable protective equipment. Self-continer breathing apparatus. Wear suitable protective clothing.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Avoid any direct contact with the product. Do not breathe vapours. Do not smoke. No flames, no sparks. Eliminate all sources of ignition. Use water spray to reduce vapours. Isolate hazard area and restrict entry. Evacuate the danger area. Do not attempt to take action without suitable protective equipment.

Environmental

Do not allow product to spread into the environment.

Cleanup methods

Wash away residue with large amounts of water
