SECTION 4: FIRST AID MEASURES
4.1. Description of First-aid Measures
General: Never give anything by mouth to an unconscious person. If you feel unwell, seek medical advice (show the label where
possible). If frostbite or freezing occurs, immediately flush with plenty of lukewarm water to GENTLY warm the affected area. Do not
use hot water. Do not rub affected area. Get immediate medical attention.
Inhalation: Obtain medical attention if breathing difficulty persists. First, take proper precautions to ensure your own safety before
attempting rescue (e.g. wear appropriate respiratory protective equipment, use the buddy system), then remove the exposed person
to fresh air. Keep at rest in a position comfortable for breathing.
Skin Contact: Remove contaminated clothing. Drench affected area with water for at least 15 minutes. Obtain medical attention if
irritation develops or persists. Thaw frosted parts with lukewarm water. Do not rub affected area. Get immediate medical
advice/attention.
Eye Contact: Rinse cautiously with water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
Obtain medical attention.
Ingestion: Rinse mouth. Do NOT induce vomiting. Obtain medical attention.
4.2. Most Important Symptoms and Effects Both Acute and Delayed
General: May cause frostbite on contact with the liquid. Asphyxia by lack of oxygen: risk of death.
Inhalation: In elevated concentrations may cause asphyxiation, central nervous system effects, and increased breathing rate.
Symptoms of asphyxiation include headache, dizziness, rapid breathing, increased pulse, mood changes, tremors, cyanosis, muscular
weakness, narcosis, numbness of the extremities, unconsciousness and death.
Skin Contact: Contact with gas/liquid escaping the container can cause frostbite and freeze burns.
Eye Contact: Contact with gas/liquid escaping the container can cause frostbite, freeze burns, and permanent eye damage.
Ingestion: Not considered a potential route of exposure, but contact with gas/liquid escaping the container can cause freeze burns
and frostbite.
Chronic Symptoms: None known.
4.3. Indication of Any Immediate Medical Attention and Special Treatment Needed
If exposed or concerned, get medical advice and attention. If medical advice is needed, have product container or label at hand.
SECTION 5: FIRE-FIGHTING MEASURES
5.1. Extinguishing Media
Suitable Extinguishing Media: Do not extinguish burning gas if flow cannot be shut off immediately. Extinguish secondary FIRES with
appropriate materials.
Unsuitable Extinguishing Media: Do not use a heavy water stream. Use of heavy stream of water may spread fire.
5.2. Special Hazards Arising From the Substance or Mixture
Fire Hazard: Extremely flammable gas.
Explosion Hazard: May form flammable/explosive vapor-air mixture. Heat may build pressure, rupturing closed containers,
spreading fire and increasing risk of burns and injuries.
Reactivity: Hazardous reactions will not occur under normal conditions.
5.3. Advice for Firefighters
Precautionary Measures Fire: Exercise caution when fighting any chemical fire. Vapors are heavier than air and may travel
considerable distance to an ignition source and flash back to source of vapors.
Firefighting Instructions: Use water spray or fog for cooling exposed containers. Leaking gas fire: Do not extinguish, unless leak can
be stopped safely. Eliminate all ignition sources if safe to do so. Fight fire remotely due to the risk of explosion.
Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory protection.
