Guidance on Safe Use
Administrative data
First-aid measures
General advice : Seek medical advice if breathing has stopped or is labored, give assisted respirations.
Supplemental oxygen may be indicated. If the heart has stopped, trained personnel should begin cardiopulmonary resuscitation immediately.
Inhalation : If breathing is irregular or stopped, administer artificial respiration.Move to fresh air.
Skin contact : Immediately remove contaminated clothing, and any extraneous chemical, if possible to do so without delay.
Flush immediately with copious amounts of water.
Initiate and maintain continuous irrigation until the patient receives medical care. If
medical care is not promptly available, continue to irrigate for one hour.
Cover wound with sterile dressing.Wash off immediately with soap and plenty of water.
Eye contact : Hold eyelids apart, initiate and maintain gentle and continuous irrigation until the patient receives medical care. If medical care is not promptly available, continue to
irrigate for one hour.Rinse immediately with plenty of water for at least 15 minutes.
Ingestion : If a person vomits when lying on his back, place him in the recovery position. Never give anything by mouth to an unconscious person.Prevent aspiration of vomit.
Turn victim's head to the side.
Fire-fighting measures
Suitable extinguishing media :
Alcohol-resistant foamCarbon dioxide (CO2)
Dry chemical
Dry sand
Limestone powder
Special hazards arising from the substance or mixture:
Incomplete combustion may form carbon monoxide.
May generate ammonia gas.
May generate toxic nitrogen oxide gases.
Burning produces noxious and toxic fumes.
Downwind personnel must be evacuated.
Advice for firefighters:
Avoid contact with skin.
A face shield should be worn.
Use personal protective equipment.
Wear self-contained breathing apparatus for firefighting if necessary.
Do not allow run-off from fire fighting to enter drains or water courses.
Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.
Accidental release measures
Personal precautions, protective equipment and emergency procedures:
Use self-contained breathing apparatus and chemically protective clothing.Evacuate personnel to safe areas.
Environmental precautions:
Construct a dike to prevent spreading.
Methods and material for containment and cleaning up:
Call Emergency Response number for advice.
Approach suspected leak areas with caution.Place in appropriate chemical waste container.
Open enclosed spaces to outside atmosphere.
If possible, stop flow of product.
Handling and storage
Precautions for safe handling
Advice on safe handling :
Use only in well-ventilated areas.
Avoid breathing vapors and/or aerosols.
Avoid contact with skin and eyes.
Avoid contact with eyes.
Emergency showers and eye wash stations should be readily accessible.
Adhere to work practice rules established by government regulations.
Use personal protective equipment.
Hygiene measures : Provide readily accessible eye wash stations and safety showers.
General protective measures : Discard contaminated leather articles.
Wash hands at the end of each workshift and before eating, smoking or using the toilet.
Do not store near acids.

Exposure controls / personal protection
Appropriate engineering controls:
Provide readily accessible eye wash stations and safety showers.
Provide natural or explosion-proof ventilation adequate to ensure concentrations are kept below exposure limits.
Eye protection: Full face shield with goggles underneath.
Hand protection : Neoprene gloves
Impervious gloves
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.
Body Protection : No specific recommendation.Impervious clothing
Respiratory protection : Not required for properly ventilated areas.Wear appropriate respirator when ventilation is inadequate.
Stability and reactivity
Stable under normal conditions.
No hazardous reactions with proper storage and handling.
Incompatible materials:
Organic acids (i.e. acetic acid, citric acid etc.).
Mineral acids.
sodium hypochlorite
Reaction with peroxides may result in violent decomposition of peroxide possibly creating an explosion.
Oxidizing agents
Hazardous decomposition products:
Carbon monoxide
Carbon dioxide (CO2)
Nitrogen oxides (NOx)
Nitrogen oxide can react with water vapors to form corrosive nitric acid.
Ammonia
Disposal considerations
Dispose of container and unused contents in accordance with natioanl and local requirements.
