Hazard Identification- Hazards may be biological, chemical, physical, mechanical or psychosocial.

Dose-Response Assessment- Measuring The amount of exposure and the subsequent response.

Exposure Assessment- Identifies and describes the population exposed, determines where and how the exposure occurs, determines the degree of exposure.

Risk Characterization- Integrates Information from hazard identification, dose response relationship, and exposure assessment. Performed to provide policymakers with a synopsis of all information about the nature of the risk including any uncertainties in enables an evaluation of it.

Risk Management- Is done after the risk assessment and is actions taken to control exposure and reduce or avoid the risk.

Factors that influence individual sensitivity- Age, sex, race, nutritional habits, physical condition, obesity, medical conditions, drinking, smoking, and pregnancy.

Additive- combination Effect is equal to the individual affect added together. An example is taking both aspirin and acetaminophen.

Synergistic- Combination Effect is greater than the sum of individual affects. Example is a smoker and asbestos are 50 to 90 times more likely for lung cancer.

Potentiation- non-toxic chemical causes another chemical to be more toxic.

Antagonistic- Chemicals in Hibbett each others actions.
