Chemical hazard

Chemical Hazard

A chemical hazard refers to a type of occupational hazard caused by exposure to chemicals in the workplace. Exposure can occur through inhalation, skin contact, or ingestion of the chemical substance.

Types of Chemical Hazards

Chemical hazards can be classified into four main types: corrosives, toxics, flammables, and reactives.

Corrosives

Corrosives are substances that can cause damage to living tissue, metals, and other materials on contact. Examples include acids and bases.

Toxics

Toxics are substances that can cause harm to the body, often by interfering with biological processes. Examples include heavy metals and certain organic compounds.

Flammables

Flammables are substances that can ignite easily and burn rapidly in the presence of a flame, spark, or heat. Examples include gasoline and alcohol.

Reactives

Reactives are substances that can undergo a chemical reaction, often releasing energy in the form of heat or light. Examples include explosives and oxidizing agents.

Risk Assessment and Management

The assessment and management of chemical hazards involves identifying the hazards, evaluating the risks associated with them, and implementing measures to control the risks. This process is often guided by regulations such as the OSHA standards in the United States.
