Three main types of laboratory hazards:

1. Chemical hazards: These include exposure to toxic, corrosive, or flammable chemicals that can cause harm through inhalation, ingestion, or skin contact. Examples of chemical hazards in the laboratory include acids, solvents, and reagents.

2. Biological hazards: These include exposure to infectious agents such as bacteria, viruses, and fungi that can cause illness or infection. Biological hazards can be present in samples, cultures, or animal tissues used in laboratory experiments.

3. Physical hazards: These include risks such as fires, explosions, electrical hazards, and ergonomic hazards that can cause injury or harm to laboratory personnel. Physical hazards can arise from equipment malfunctions, improper handling of materials, or unsafe laboratory practices.
