Invasive means: inhalation Ingestion
Health hazard: inhalation of dust from zinc oxide zinc casting heat. I have the symptoms of metallic taste, thirst, Yangan, loss of appetite, chest, tight, dry cough, headache, dizziness, limb pain, high fever Wuhan. Zinc oxide could be a lot of dust and caused obstruction of sebaceous skin papules and eczema.
Blasting risk: The drug Noncombustible.
 
3, first-aid measures

Eye contact: opened eyelids, use of mobile water rinse for 15 minutes. For medical treatment.
Inhalation: from the scene to fresh air. For medical treatment.
Ingestion: mistaken consumption, oral milk, soy milk or egg white, gastric lavage. For medical treatment.
 
4, fire measures
Hazardous characteristics: magnesium, flax seed oil in fierce reaction. With a mixture of chlorinated rubber heated to above 215 ℃ possible explosion. Decomposition by high fever, the release of toxic gas.
Harmful combustion products: zinc oxide.
Fire fighting methods and extinguishing agents: systemic fire officers must wear anti-virus service, the wind direction on fire. Noncombustible. Available around the scene of the fire extinguishing media.
 
5, leakage of emergency
Emergency Treatment: isolation leak polluted area, located around the warning signs, the proposed emergency personnel wearing masks good, goggles, wearing overalls. So carefully, to avoid dust, deep inverted to open areas. Can also use a lot of water washing, the dilution of the washing water into wastewater systems. Such as the large number of spills, recycling or collection of sound waste treatment.
 
6, storage and disposal operation
Operation Note: confined operation, local exhaust. The operator must go through specialized training and strictly abide by the rules. Recommended operating officer wearing self-absorption filter-dust masks, wearing protective chemical safety glasses, wearing anti-virus infiltration of uniform, wearing latex gloves. Avoid dust. Avoid contact with the oxidant. Carrying, Qingzhuang light unloading, packaging to prevent breakage. Equipped with emergency equipment leakage. Empty containers may be harmful residues of.
Save Attention: stored in a cool, ventilated coffers. Away from the fire, heat. Should be kept separate from and oxidizer must not mix certificates. Reservoir areas should be equipped with suitable material asylum spill.
 
7, exposure control / Personal Protection
The maximum admissible concentration: MAC: 5mg/m3 the former Soviet Union MAC: 0.5mg/m3 U.S. TLV-TWA: 5mg / m
Engineering controls: closed operation, local exhaust.
Respiratory Protection: Workers wearing dust masks recommendations.
Eye protection: safety masks when necessary, can be.
Physical protection: Wear tight sleeves overalls, rubber shoes longituba.
Hand protection: wear protective gloves.
Other protective: no smoking at work, eating and drinking water. After work, shower changing. To pay attention to personal hygiene.

11, waste disposal
Waste disposal: the disposal of security buried
 
12, transport information
Packaging:
Transport Attention: stored in a cool, ventilation between the positions. Away from the fire, heat. Remain sealed containers, with the oxidant, consumption of chemicals stored separately. Carrying, to Qingzhuang light unloading, packaging and containers to prevent damage. Packaging and handling operations to pay attention to personal protection.
 
13, regulatory information
Domestic chemical safety regulations: Chemical Safety Management of Dangerous Goods Ordinance (February 17, 1987 the State Council), the chemical safety management of the Dangerous Goods Regulations (of labour, [1992] 677), the workplace safe use of chemicals regulations ([1996] No. 423 of the Labour Department) and other regulations, dangerous goods for the safety of chemical use, production, storage, transport, handling and so on a corresponding provisions.
