Detailed explanation-1: -Chemical hazards and toxic substances pose a wide range of health hazards (such as irritation, sensitization, and carcinogenicity) and physical hazards (such as flammability, corrosion, and explosibility).

Detailed explanation-2: -Toxicological studies includes the detection, identification, and quantification of hazards ensuing from human exposure to chemicals (smoke, food, and workplace), public health aspects of toxic agents in the environment (air, water, and soil), and testing of novel pharmaceutical products.

Detailed explanation-3: -Physical hazard are based on the intrinsic properties of the chemical. There are five main classes of physical hazard namely Explosive, Flammable, Oxidising, Gases under Pressure and Corrosive to metals.
