Chemical Exposure

Brief Overview

The term “chemical exposure monitoring” typically means the measurement of employee exposure to airborne vapors, mists, fumes or dust particles. Chemical hazards and toxic substances pose a wide range of health hazards such as irritation, sensitization, and carcinogenicity. This monitoring is used by occupational health and safety professionals to assess workplace contaminants and associated worker exposures.

Why it is Needed?

Where there is uncertainty of the risk of the chemicals used by the employees, chemical monitoring is conducted. This is to ensure that employee exposure to airborne chemicals are within permissible limits. These permissible exposure limits (PELs) have been established by the Occupational Safety and Health Administration (OSHA)

How to conduct?

The validity of an assessment is based, in part, on the procedures used for sample collection and analysis and data interpretation. The monitoring is conducted by a competent person, known as the Industrial Hygiene Technician 1 registered with the Department of Occupational Safety & Health, Malaysia. Source of hazardous chemicals is determined, a portable sampling pump attached with specific sampling media is placed on the employee’s body for the monitoring during his/her normal working period. The sampling media will then be sent for analysis in the laboratory. Report will be presented once laboratory results are ready. Specification of exposure to hazardous chemicals will be based on Occupational Safety & Health Regulations 2000. (Use and Standards of Chemicals Hazardous to Health (USECHH) Regulations 2000).
