*While not a requirement of the regulation, occupational hygiene professionals registered by the Canadian Registration Board of Occupational Hygienists or certified by the American Board of Occupational Hygienists are examples of individuals who may be qualified persons. Having air sampling conducted by, or under the supervision of, a qualified person in industrial hygiene can help ensure that sampling is carried out in accordance with the regulation and the results are representative of worker exposures. It is ultimately the employer’s responsibility to ensure that the regulatory requirements are met. An employer may use their own staff if they are qualified or engage outside personnel who are qualified to perform or supervise the work. Who can conduct air samplingĪir sampling must be performed by, or under the direction of, a person who is qualified because of knowledge, training and experience in industrial hygiene practice* (section 24). It is important to ensure that the method used, the sampling done and the results analyzed are all done in compliance with the regulation. There are a wide variety of sampling methods. to record the personal exposure of workers to the designated substance.to ensure that respirators are appropriate for the concentration of the designated substance.t o obtain information that will aid in the selection of additional controls including respirators.to evaluate the effectiveness and performance of existing controls.to demonstrate compliance with the OELs.to determine the extent of exposure to the designated substance.There are several reasons why air sampling is carried out, including:

The methods and procedures to monitor airborne concentrations of and worker exposure to designated substances must be included in control programs. It usually involves collecting representative samples of the substance from the air and having them analyzed to determine the quantity of the substance present.Īir sampling assesses a worker’s exposure by inhalation. Air samplingĪir sampling refers to a procedure for determining the concentration of a contaminant in workplace air. The requirements of section 24 of the regulation must be considered and adhered to in the development of the program. To fulfil this requirement workplaces should develop an “air monitoring program” that, among other things, specifies when and where to conduct air sampling, how often and the methods to be used. The methods and procedures to monitor airborne concentrations of and worker exposure to airborne concentrations of designated substances must be included in control programs (subsection 20(2)).
