Explanation:

The SDS also informs that:

Most Important Hazards:

May cause severe burns to skin, eyes and mucous membranes.  Steam produced is irritating.  Pollution of rivers and water bodies by changing the pH. Affects flora and fauna that comes in contact with acid.

Product Effects:

 Inhalation causes severe respiratory tract irritation. May cause pulmonary edema. The contact  with the skin causes burns, which can lead to dermatitis. Prolonged contact of acid leads to  visual damage to vision loss. If swallowed, may cause burns to the mucous membranes of the mouth and  digestive system.

Environmental Effects:

 Affects rivers and streams by changing the pH of the water. May contaminate the soil. Vapors may  temporarily affect air quality.

Physical and chemical hazards:

 Reacts with metals such as; iron, aluminum, zinc, magnesium, among others, forming hydrogen, which  mixed with air may cause explosion and air displacement upon ignition under  specific.
