Human body harm and protection

[Health hazards]: the eyes, respiratory mucosa have a strong stimulating effect, severe cases can cause pulmonary edema. Can cause skin irritation.
[Invasive approach]: inhaled ingested percutaneous absorption
[Skin contact]: Immediately remove contaminated clothing, rinse thoroughly with plenty of flowing water.
[Eye contact]: immediately filed eyelid, with mobile water or saline for at least 15 minutes.
[Inhalation]: Quickly disengage from the scene to fresh air. Note that warm, breathing difficulties when oxygen. When breathing stops, perform artificial respiration immediately. Get medical attention.
[Ingestion]: When the patient awake immediately gargle, to drink milk or egg white. Get medical attention.
[Respiratory protection]: It may be exposed to vapor, it should wear gas masks. Emergency rescue or escape, wearing self-contained breathing apparatus.
[Eye protection]: Wear chemical safety glasses.

Storage and Leakage Handling

[Storage and transportation precautions]: Stored in a cool, ventilated warehouse. Keep away from fire and heat. Storage temperature should not exceed 30 ℃.
To prevent direct sunlight. Keep the container sealed. Should be oxidant, edible chemical raw materials stored separately.
Handling to light loading and unloading to prevent damage to packaging and containers. Pay attention to personal protection during packing and handling.
[Leak disposal]: evacuate people living in contaminated areas to a safe area, prohibit unrelated persons from entering the contaminated area, cut off the fire source.
Recommended emergency personnel wearing self-contained breathing apparatus, wear chemical protective clothing. Do not directly contact the spill, plugging to ensure safety.
Spray water to reduce evaporation. Mixed with sand or other non-flammable absorbent absorption, and then transported to the collection and disposal of waste disposal sites.
It can also be treated with an alkaline substance. Such as large leaks, the use of dike embankment, and then collect, transfer, recycling or harmless disposal.
[Engineering Control]: Strictly sealed to provide adequate local exhaust. As far as possible mechanization, automation.
