| toxicity | toxic and corrosive hydrogen fluoride smoke is produced in humid air. It has a severe irritation to the skin, eyes, and mucous membranes. Inhalation can cause respiratory tract inflammation and pulmonary edema. Patients who inhale gas should be removed from the contaminated area, placed to rest and keep warm. In severe cases, they must seek medical treatment. If you accidentally splash your eyes, you should rinse them with plenty of water for 15min and seek medical treatment. If the skin is contaminated, rinse with plenty of water, and if burned, seek medical attention. |
