The third part: risk overview
Risk categories:
Invasive way:
Health hazard: acute poisoning mainly for Ma Zui effects on the central nervous system, fatigue, nausea, headache, dizziness,irritability. In serious cases of vomiting, shortness of breath,cramps, and even coma. Eye, nose, and throat irritation. After oral administration, first lips, throat burning, dry mouth, aftervomiting, coma, and ketosis acid poisoning. Chronic effects:long-term exposure to the goods appear dizziness, burning sensation, pharyngitis, bronchitis, fatigue, irritability and other.The long-term repeated exposure may cause skin dermatitis.
Environmental hazards:
Fire and explosion hazards: This product extremely flammable,irritating.
The fourth part: first aid measures
Skin contact: remove contaminated clothing, wash thoroughlywith soap and water and clean water for skin.
Eye contact: filed eyelid, rinse with water or saline. Medical treatment.
Inhalation: remove to fresh air. To maintain airway patency. If breathing is difficult, give oxygen. If not breathing, artificial respiration immediately. Medical treatment.
Ingestion: drink plenty of warm water, emetic. Medical treatment.
The fifth part: fire protection measures
Hazardous characteristics: its vapor and air can form explosive mixtures, the event of fire, burning heat easily explosion. It can react with oxidants. The vapor is heavier than air, to the lower at a far place diffusion, meeting fire will fire backdraft. In case of high fever, increased pressure within the container, cracking and explosion.
Hazardous combustion products: carbon monoxide, carbon dioxide.
Fire extinguishing method: as far as possible the vessels to an open area. Keep the fire water spray container cooling, until the fire is extinguished. If the containers in the fireground havediscoloration or from the sound generated pressure safety reliefdevice, must evacuate immediately. Fire extinguishing agent: anti insoluble foam, carbon dioxide, dry, sandy soil. Water fire invalid.
The sixth part: Leakage Emergency Treatment
Emergency treatment: leakage of contaminated areas to evacuate personnel to a safe area, and isolation, strict restrictions on access. Cut off the fire source. Recommended emergency personnel wear self positive pressure respirator,wear anti-static clothing. As far as possible to cut off the source of leakage. To prevent it from flowing into the sewer drainage ditch, confined space. Small spills: absorb with sand or other non combustible material adsorption or. Also can rinse with plenty of water, wash water diluted into the wastewater system. Large spills: constructing dike or dig a hole. Covered with foam, lower vapor disasters. Explosion proof pump transferred totankexclusive collector, site for the disposal of recycled ortransported to the waste disposal.
The seventh part: handling and storage
Matters needing attention: closed operation, overall ventilation.The operator must go through specialized training, strictly abide by the rules. Proposed operators wear filtration mask (half mask), wear safety glasses, wear anti-static overalls, wearing rubber oil resistant glove. Away from fire, heat source, smoking is prohibited in the workplace. Use explosion-proof ventilation systems and equipment. To prevent steam leakage in the air of workplace. Avoid contact with oxidizing agent, reducing agent,alkali. Filling should control the flow rate, and the grounding device, to prevent the accumulation of static electricity. When moving to light light unloading, prevent damage to packagingand containers. Equipped with the appropriate variety and quantity of fire fighting equipment and leakage emergencytreatment equipment. May be left empty containers of hazardoussubstances.
Storage note: store in a cool, ventilated warehouse. Away from fire, heat source. Not more than 26 DEG C temperature. Keep the container sealed. Should be stored with the oxidant, reducing agent, alkali separately, avoid mixing reservoir. The use of explosion-proof type lighting, ventilation facilities. Mechanical equipment and tools to prohibit the use of easy to producesparks. Storage areas should be equipped with emergency treatment equipment and suitable housing materials.

Engineering controls: production process is sealed, general ventilation.
Respiratory protection: air chroma, wear filtration mask (half mask).
Eye protection: do not need special protection, can wear safety glasses high concentration exposure.
Body protection: wear anti-static overalls.
Hand protection: wear rubber oil resistant glove.
Other protection: work site smoking. Pay attention to personal hygiene. Avoid long-term repeated exposure.
