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.
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.
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

:
No action shall be taken involving any personal risk or without suitable training. It may
be dangerous to the person providing aid to give mouth-to-mouth resuscitation.
See toxicological information (Section 11)
Section 5. Fire-fighting measures
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. If involved in fire, shut off flow immediately if it can be done without risk.

No action shall be taken involving any personal risk or without suitable training.
Evacuate surrounding areas. Keep unnecessary and unprotected personnel from
entering. Shut off all ignition sources. No flares, smoking or flames in hazard area.
Avoid breathing gas. Provide adequate ventilation. Wear appropriate respirator when
ventilation is inadequate. Put on appropriate personal protective equipment.
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).

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). 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). Separate from reducing
agents and combustible materials. Store away from grease and oil. Keep container
tightly closed and sealed until ready for use. See Section 10 for incompatible materials
before handling or use.
:
:
Protective measures
Put on appropriate personal protective equipment (see Section 8). Contains gas under
pressure. Avoid breathing gas. 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.
Avoid contact with eyes, skin and clothing. Empty containers retain product residue
and can be hazardous. Keep away from clothing, incompatible materials and
combustible materials. Keep reduction valves free from grease and oil.

Section 8. Exposure controls/personal protection
Ingredient name
Exposure limits
Hand protection
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.
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.
Eye/face protection
:
:
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.
Appropriate engineering
controls
:
Good general ventilation should be sufficient to control worker exposure to airborne
contaminants.
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.

Section 8. Exposure controls/personal protection
Based on the hazard and potential for exposure, select a respirator that meets the
appropriate standard or certification. Respirators must be used according to a
respiratory protection program to ensure proper fitting, training, and other important
aspects of use. 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.
Respiratory protection
:
Body protection
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.

Other skin protection
:
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
