A chemical hazard is a type of occupational hazard caused by exposure to chemicals in the workplace. Exposure to chemicals in the workplace can cause acute or long-term detrimental health effects. There are many types of hazardous chemicals, including neurotoxins, immune agents, dermatologic agents, carcinogens, reproductive toxins, systemic toxins, asthmagens, pneumoconiotic agents, and sensitizers.

Chemicals can change their physical state depending on temperature or pressure. Thus it is important to identify the health risks as these states can determine the potential route the chemical will take. For example, gas state chemicals will be inhaled or liquid state chemicals can be absorbed by the skin.
