Description of necessary first aid measures

Inhalation : 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.

Ingestion : Wash out mouth with water. Remove dentures if any. Remove victim to fresh air and keep at rest in aposition comfortable for breathing. If material has been swallowed and the exposed person is conscious, give small quantities of water to drink. Stop if the exposed person feels sick as vomiting may be dangerous. Do notinduce

vomiting  unless directed to do so by medical personnel. If vomiting occurs, the

head should be  kept low so that vomit does not enter the lungs. Get medical

attention if adverse  health effects persist or are severe. Never give anything by

mouth to an unconscious  person. 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.

Skin contact:  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.

Eye contact : 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.

Extinguishing media

Suitable : Use an extinguishing agent suitable for the surrounding fire

Not suitable : none known

Specific hazards arising : In a fire or if heated, a pressure increase will occur and the container may burst from the chemical     This material is toxic to aquatic life with long lasting effects. Fire water

contaminated with this material must be contained and prevented from being                      discharged to any

waterway, sewer or drain.

Hazardous thermal :    Decomposition products may include the following materials: decomposition products  carbon dioxide; carbon monoxide ; nitrogen oxides

Special precautions for Promptly isolate the scene by removing all persons from the vicinity of the  fire- fighters: incident if there is a fire. No action shall be taken involving any personal risk or without suitable training.

Remark : Not  available.

SECTION 6 Leakage Emergency Measures

Emergency measures&

Personal protection: keep away from eyes and wear protective articles.

Environment protection ： limit entry of nonproduction workers and collect and put leakage

material in sealed container, rinse the spot and discharge waste water into specified water treatment system.

SECTION 7   Handle and storage

Handle

Take care of load and unload in order to avoid sprinkle due to package breakage. easily agglomerate exposed to the moisture, it’s unadvisable to handle them when raining, unless under rain shelter.

Advices on general occupational hygiene:

When using do not eat, drink, smoke, sniff.

Wash hands before breaks and after work.

Used working clothes should not be worn outside the work area.

Storage

Can be stored one year in cool and well-ventilated warehouse, avoid insolation, seal the bag immediately after use, the shelf life is 12 months.

SECTION 8 Protection Measures

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.

Engineer Control: keep workshop and storage room ventilated and materials sealed.

Operation Protection: keep materials away from eyes and ventilate during production and usage.

Thoroughly rinse after operation.

Personal Protection :

Hand protection : Chemical-resistant, impervious gloves complying with an approved standard should

be worn at all times when handling chemical products ifa risk assessment indicates this is necessary.

Use gloves approved to relevant standards e.g.  EN   374 (Europe), F739 (US). Suitability and durability of a glove is dependent on  usage, e.g. frequency and duration of contact, chemical resistance of glove

material and dexterity. Always seek advice from glove suppliers.

Eye protection :  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 side-shields.

Skin 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.
