Section 4. First aid measures
Description of necessary first aid measures
Eye contact
Inhalation
Skin contact
Ingestion
: Immediately flush eyes with plenty of water, occasionally lifting the upper and lower
eyelids. Check for and remove any contact lenses. Continue to rinse for at least 10
minutes. Get medical attention if irritation occurs.
: Remove victim to fresh air and keep at rest in a position comfortable for breathing. If
not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial
respiration or oxygen by trained personnel. It may be dangerous to the person providing
aid to give mouth-to-mouth resuscitation. Get medical attention if adverse health effects
persist or are severe. If unconscious, place in recovery position and get medical
attention immediately. Maintain an open airway. Loosen tight clothing such as a collar,
tie, belt or waistband. In case of inhalation of decomposition products in a fire,
symptoms may be delayed. The exposed person may need to be kept under medical
surveillance for 48 hours.
: Flush contaminated skin with plenty of water. Remove contaminated clothing and
shoes. Get medical attention if symptoms occur. Wash clothing before reuse. Clean
shoes thoroughly before reuse.
: As this product is a gas, refer to the inhalation section.

nitrogen oxides
Special protective actions
for fire-fighters
: Promptly isolate the scene by removing all persons from the vicinity of the incident if
there is a fire. No action shall be taken involving any personal risk or without suitable
training. Contact supplier immediately for specialist advice. Move containers from fire
area if this can be done without risk. Use water spray to keep fire-exposed containers
cool.
: Fire-fighters should wear appropriate protective equipment and self-contained breathing
apparatus (SCBA) with a full face-piece operated in positive pressure mode.
Special protective
equipment for fire-fighters
Section 6. Accidental release measures
Personal precautions, protective equipment and emergency procedures
For non-emergency
personnel
: No action shall be taken involving any personal risk or without suitable training.
Evacuate surrounding areas. Keep unnecessary and unprotected personnel from
entering. Avoid breathing gas. Provide adequate ventilation. Wear appropriate
respirator when ventilation is inadequate. Put on appropriate personal protective
equipment.
For emergency responders : If specialised clothing is required to deal with the spillage, take note of any information
in Section 8 on suitable and unsuitable materials. See also the information in "For nonemergency personnel".
Environmental precautions
: Ensure emergency procedures to deal with accidental gas releases are in place to avoid
contamination of the environment. Inform the relevant authorities if the product has
caused environmental pollution (sewers, waterways, soil or air).
Methods and materials for containment and cleaning up
Small spill
: Immediately contact emergency personnel. Stop leak if without risk.
Large spill
: Immediately contact emergency personnel. Stop leak if without risk. Note: see Section
1 for emergency contact information and Section 13 for waste disposal.

Precautions for safe handling
Protective measures
Date of issue/Date of revision
: Put on appropriate personal protective equipment (see Section 8). Contains gas under
pressure. Avoid contact with eyes, skin and clothing. Avoid breathing gas. Empty
containers retain product residue and can be hazardous. Do not puncture or incinerate
container. Use equipment rated for cylinder pressure. Close valve after each use and
when empty. Protect cylinders from physical damage; do not drag, roll, slide, or drop.
Use a suitable hand truck for cylinder movement.

Section 7. Handling and storage
Advice on general
occupational hygiene
Conditions for safe storage,
including any
incompatibilities
: Eating, drinking and smoking should be prohibited in areas where this material is
handled, stored and processed. Workers should wash hands and face before eating,
drinking and smoking. Remove contaminated clothing and protective equipment before
entering eating areas. See also Section 8 for additional information on hygiene
measures.
: Store in accordance with local regulations. Store in a segregated and approved area.
Store away from direct sunlight in a dry, cool and well-ventilated area, away from
incompatible materials (see Section 10). Keep container tightly closed and sealed until
ready for use. Cylinders should be stored upright, with valve protection cap in place,
and firmly secured to prevent falling or being knocked over. Cylinder temperatures
should not exceed 52 °C (125 °F).

Oxygen Depletion [Asphyxiant]
Appropriate engineering
controls
: Good general ventilation should be sufficient to control worker exposure to airborne
contaminants.
Environmental exposure
controls
: Emissions from ventilation or work process equipment should be checked to ensure
they comply with the requirements of environmental protection legislation. In some
cases, fume scrubbers, filters or engineering modifications to the process equipment
will be necessary to reduce emissions to acceptable levels.
Individual protection measures
Hygiene measures
Eye/face protection
: Wash hands, forearms and face thoroughly after handling chemical products, before
eating, smoking and using the lavatory and at the end of the working period.
Appropriate techniques should be used to remove potentially contaminated clothing.
Wash contaminated clothing before reusing. Ensure that eyewash stations and safety
showers are close to the workstation location.
: Safety eyewear complying with an approved standard should be used when a risk
assessment indicates this is necessary to avoid exposure to liquid splashes, mists,
gases or dusts. If contact is possible, the following protection should be worn, unless
the assessment indicates a higher degree of protection: safety glasses with sideshields.
Skin protection
Hand protection
Body protection
Other skin protection
Respiratory protection
Date of issue/Date of revision
: Chemical-resistant, impervious gloves complying with an approved standard should be
worn at all times when handling chemical products if a risk assessment indicates this is
necessary. Considering the parameters specified by the glove manufacturer, check
during use that the gloves are still retaining their protective properties. It should be
noted that the time to breakthrough for any glove material may be different for different
glove manufacturers. In the case of mixtures, consisting of several substances, the
protection time of the gloves cannot be accurately estimated.
: Personal protective equipment for the body should be selected based on the task being
performed and the risks involved and should be approved by a specialist before
handling this product.
: Appropriate footwear and any additional skin protection measures should be selected
based on the task being performed and the risks involved and should be approved by a
specialist before handling this product.
: Use a properly fitted, air-purifying or air-fed respirator complying with an approved
standard if a risk assessment indicates this is necessary. Respirator selection must be
based on known or anticipated exposure levels, the hazards of the product and the safe
working limits of the selected respirator.

Handling
Storage
: Do not puncture or incinerate container. High pressure gas. Use equipment rated for
cylinder pressure. Close valve after each use and when empty. Protect cylinders from
physical damage; do not drag, roll, slide, or drop. Use a suitable hand truck for cylinder
movement.
Never allow any unprotected part of the body to touch uninsulated pipes or vessels that
contain cryogenic liquids. Prevent entrapment of liquid in closed systems or piping
without pressure relief devices. Some materials may become brittle at low temperatures
and will easily fracture.
: Keep container tightly closed. Keep container in a cool, well-ventilated area. Cylinders
should be stored upright, with valve protection cap in place, and firmly secured to
prevent falling or being knocked over. Cylinder temperatures should not exceed 52 °C
(125 °F).
