Employees can be exposed to chemical agents through three main routes: skin contact; ingestion; and inhalation. While exposures by skin absorption and ingestion are relatively easily recognised and controlled, the evaluation of inhalation hazards is more complex. Chemical exposure monitoring (of airborne vapours or particles of hazardous chemicals) will be required to confirm whether specific hazardous chemicals are present and to determine if the concentration presents a health risk to employees.

According to USECHH reg.2000, Part 1, under clause Duty of Employer, the employer should take necessary action to reduce and maintain the exposure level of employees to chemical hazardous to health to:

The lowest practicable level

Below the permissible exposure limits

Section 26 USECHH reg.2000 stated that, monitoring is to be conducted on employees exposure to chemical hazardous to health listed in Schedule II of the USECHH Regulation 2000 and where CHRA recommend monitoring to be conducted in accordance with an approved method of sampling and analysis for the chemical hazardous to health. Workplace exposure monitoring also may be required for other reason such as:

• To ensure the employees exposure level are maintained below the Permissible Exposure Limits
• To ensure the maintenance of adequate control measure
• To quantify exposure during new process set-up
• To assess the effects of a change in process specification
• To ensure that the risk assessment is still valid
