Answer 1

The hazards of substances used in a formal laboratory environment include burns, irritations, and toxic fumes. Precautions should be taken to protect oneself from these hazards. Avoid contact with skin and eyes. Work in a well-ventilated area or use fume hoods to minimize exposure to toxic fumes.

Step-by-step explanation:

Hazards of Substances:Hydrochloric acid: It is a corrosive substance that can cause severe burns to the skin and eyes. Inhalation of its fumes can irritate the respiratory tract.Bleach: It contains sodium hypochlorite, which can irritate and burn the skin and eyes. Mixing it with certain chemicals, such as ammonia, can produce toxic gases.Hydrogen peroxide: It can irritate the skin, eyes, and respiratory system. High concentrations may cause burns.

Precautions in a Formal Laboratory: Always wear appropriate personal protective equipment, such as gloves, goggles, and lab coats. Handle chemicals with care, following the instructions provided. Avoid contact with skin and eyes. Work in a well-ventilated area or use fume hoods to minimize exposure to toxic fumes.
