5. Environmental standards
China (TJ36-79) Workshop harmful substances in the air that the maximum allowable concentration 1mg (F) / m3

6. Emergency treatment and disposal methods
a leakage disposal

isolation leakage, based warning signs. Emergency personnel wearing protective equipment, wearing gas masks entered the scene. Soda and hydrated lime used and also can be used industrial vacuum cleaners to clear.

two protective measures

confined generation process, the scene enhanced ventilation. Operators on wearing protective clothing, wearing goggles, gloves, use appropriate respirators equipped with a shower and eye-wash facilities between.

three, and emergency measures

eye contact with the slow flow of water washing for at least 15 minutes. Skin contact, the pollution off the clothing, wash with soap for at least 15 minutes, patients will be moved to fresh air, if necessary oxygen or mouth. Nose bleeding at the nose squeezed within absorbent material, and frequently replaced. Wrongly, egg white or milk to drink and to seek medical treatment.
