4. First Aid Measures
First Aid Skin Wash off with water.
Remove clothing.
Shower thoroughly.
First Aid Eyes Flush eyes with water for 15 minutes.
Hold eyelids open while washing.
Seek medical attention.
First Aid Ingested Do not induce vomiting.
Give large amounts of water.
Seek medical attention.
First Aid Inhalation Remove from contaminated area.
Give oxygen.
CPR if indicated.
Seek medical attention.
5. Fire Fighting Measures
Solution is non flammable but may assist combustion.
Contain fire and allow to burn.
Move container from fire area if you can do it without risk.
Cool containers that are exposed to flames with water from the side until well after the fire
is out.
Stay away from ends of tanks.
Keep unnecessary people away; isolate hazard area and deny entry.
Thermal decomposition product is chlorine gas - stay upwind; keep out of low areas.
Use self contained breating apparatus and chemical protective clothing.
Use an extinguishing media appropriate for the maqterial that is burning.
Do not allow run-off from fire fighting to enter sewers or water courses.
6. Accidental Release Measures
Full protective clothing including breathing apparatus
Dilute (substance may be washed to drain with a lot of water)
PRECAUTIONS:
Restrict access to area.
Provide adequate protective equipment and ventilation.
Always work upwind from the spill.
Remove sources of heat and flame.
Notify occupational and environmental authorities.
SPILL OR LEAK:
Do not touch spilled material.
Stop leak if you can do it without risk.
Use water spray to reduce vapours.
SMALL SPILLS:
Takeup with sand or other noncombustible absorbent material

7. Handling And Storage
HANDLING
Avoid contact with eyes or skin and do not breath in mist.
Avoid generation of mist.
Keep away from cleaning agents.
STORAGE
Keep containers in cool ventilated areas away from sunlight.
Keep away from acids, ammonia salts, amines, methanol.
8. Exposure Controls/Personal Protection
Occupational Exposure Limits TWA - OEL - RL not listed
In case of chlorine emmission, observe OEL for chlorine
TWA - OEL - RL = 1.5 mg/m3 Cl2
Short term OEL - RL = 3 mg/m3 Cl2
Controls The control measures appropriate for a particular worksite
depend
on how this material is used and on the extent of exposure.
The best protection is to enclose operations and/or provide
local exhaust ventilation at the site of chemical release.
Use a non-sparking, grounded ventilation system separate
from other
exhaust ventilation systems. Exhaust directly to the outside.
Supply sufficient replacement air to make up for air removed.
Have a safety shower/eye wash fountain readily available in
the immediate work area
Personal Protection If engineering controls and work practices are not effective in
controlling this material, then wear suitable personal
protection
equipment, including chemical safety goggles & face shield,
boots,
imperious gloves, coveralls, & respiratory protection.
Have appropriate equipment available for use in emergencies.

heat and UV light.
Product should be diluted asap to at least 6 % to improve stability.
Shelf life at 12.5 % is approximately 1 week, before it starts to deteriorate.
10. Stability And Reactivity
Conditions to Avoid High temperatures and light will cause the product to
deteriorate. Precipitates (chlorates) will form and the product
will turn brown/black. Gas will form which may lead to
containers bursting.
Incompatible Materials Reacts with acids and releases toxic chlorine gas and oxygen.
Powerful oxidizing agent.
Other Thermal decomposition product will evolve toxic chlorine and
sodium dioxide fumes.
11. Toxicological Information
Acute toxicity:
Released Chlorine is toxic by inhalation.
Skin and eye contact:
Irritating to skin causing burns.
Chronic toxicity:
Prolonged exposure to skin will result in dermatitis, to eyes - conjunctivitis, inhalation -
adversely effect respiratory tract.
12. Ecological Information
No ecological problems are expected when the product is handled and used with due care.
13. Disposal Considerations
Disposal Method Product There are no uniform EC regulations for the disposal of
chemicals or residues.
Chemical residues generally count as special waste.
The disposal of the latter is regulated in the EC member
countries through corresponding laws and regulations.
We recommend that you contact the authorities in charge or
approved
waste disposal companies which will advise you on how to
dispose of special waste.
Disposal Method Packaging Disposal in accordance with local legal provisions.
