4.1 Description of necessary first aid measures

General advice: Remove victim from contaminated area immediately. Keep warm and at rest. Show this SDS to attending physician.

Inhalation:

• Move victim to fresh air immediately. Keep airway clear.
• Administer oxygen if breathing is difficult.
• If not breathing, give artificial respiration (preferably with bag-valve-mask or pocket mask; avoid mouth-to-mouth).
• If no pulse, start cardiopulmonary resuscitation (CPR) immediately.
• Keep victim warm and at rest. Monitor condition closely.
• Seek medical attention immediately.

Skin contact (frostbite):

• Immediately flush affected area with large amounts of lukewarm water (37–40°C) to promote rewarming.
• Do NOT use hot water (>40°C) or direct heat (e.g., electric heaters).
• Do NOT rub or massage frostbitten area; this may worsen tissue damage.
• Carefully remove frozen clothing. If clothing sticks to skin, do NOT pull it off; cut around it.
• Cover with sterile dressing.
• Seek medical attention immediately.

Eye contact:

• Immediately hold eyelids open and rinse thoroughly with plenty of water or normal saline for at least 15 minutes.
• Ensure complete irrigation of all eye surfaces by lifting upper and lower lids.
• Remove contact lenses if present and easily removable.
• Seek medical attention immediately, preferably from an ophthalmologist.

Ingestion:

5.4 Advice for firefighters

• Firefighters must wear positive-pressure self-contained breathing apparatus (SCBA) and full protective fire-resistant clothing.
• If possible, move containers from fire area to a safe location.
• Cool containers with water spray from a safe distance until fire is extinguished.
• Immediately evacuate if containers show discoloration or if pressure relief devices begin to vent.
• Isolate the area; keep unauthorized personnel out.
• Avoid direct water spray on leaking liquefied gas, as this will accelerate evaporation and dispersion.

6.1 Personal precautions, protective equipment and emergency procedures

• Evacuate personnel from the leak area to upwind locations immediately. Establish a perimeter and restrict access.
• Emergency responders should wear SCBA, standard work clothing, cryogenic gloves, and eye protection.

• Stop leak if it can be done safely.
• Do not touch or walk through spilled material.
• Maintain emergency contact personnel for external support.

6.2 Environmental precautions

• Prevent gas from entering sewers, basements, or confined spaces.
• Ventilate the area to accelerate dispersion.
• Minimize releases to control greenhouse gas emissions; recover whenever possible.
• Avoid release to atmosphere, waterways, or soil.

6.3 Methods and materials for containment and cleaning up

• Small leak: Increase ventilation to accelerate gas dispersion. Monitor oxygen levels to prevent asphyxiation.
• Large leak:
  • Close source valve if safe to do so.
  • Recover using dedicated gas recovery equipment.
  • If recovery is not possible, use water fog/mist to dilute and dissolve gas (prevent water pollution).
  • If cylinder valve cannot be closed, immerse cylinder in alkaline water solution for absorption.
• Cylinder leak: Move cylinder to a well-ventilated safe area and vent slowly. If valve cannot be closed, contact supplier for professional handling.
