Eyes contact：slight irritation
Skin contact：normally no sensitivity
Taking orally by accident：not fatal by small amount
4.
First Aid
Inhalation：keep away from contact and transfer to fresh air environment. If dyspnea continues, turn to
doctors.
Skin contact：clean the skin with soap and clean water and daub some skin-care balm. If irritation is
severe, turn to doctors.
Eyes contact：use clean water to rinse 15 minutes. If irritation is severe, turn to doctors.
Taking orally by accident：drink 3-4 cups of water and milk, and you may press the throat to vomit.
However, if the patient is unconscious, turn to the hospital at once and don’t give him anything for oral
taking.
Instruction for doctors: normally not fatal, but the possibility of chronic poisoning is unknown.
5.
Fire Fighting
Flash point：297℃
Self-ignition Point：＞350℃
Special Danger：When the product powder is mixed with air or oxidation medium, explosive blend will
form, thus preventing the creation of powder and fire source. All the devices and containers contacting the
product should take static electricity earthing.
Steps for putting out fire：cut in from the uptake, and avoid inhaling smoke. Wear gas mask or self-help
inspirator in case of heavy smoke.
Materials for putting out fire: chemical dry powder, phosphor dioxide, foam, spray.
Harmful thermo decomposition product: carbon monoxide, carbon dioxide, aromatics, low-molecular
hydrocarbon.
6.
Leakage Emergency
Sweep the materials or use vacuum cleaning, and put them in special recycling container, wash the floor
with clean water.
