If you have never done air sampling before, you may wish to take advantage of some of the free training materials available on the SKC website.

The health and safety professional may need to use a basic mathematical formula to calculate the 8-hour time-weighted average if the sample was not collected over the 8-hour day. This result is then compared to the exposure levels allowed by the governing authority or the individual corporation. The laboratory will typically report the concentrations of the designated airborne contaminant in milligrams per cubic meter of air (mg/m3) for particulates or in parts per million (ppm) for gases/vapors. Also, like sorbent sample tubes, they must be analyzed by a qualified laboratory. These samplers however should have scientific validation to ensure their reliability for your target compounds. After sampling, the collection media is removed from the worker and sent to a laboratory for analysis.Īlternatively, passive air sampling can be done for some gases/vapors using small badge-like samplers.These are smaller, less obtrusive for the workers, and do not require a pump. Sampling is typically done for the entire work shift to properly evaluate the exposure level. When the pump is turned on, the air contaminant is pulled onto the collection media. Alternatively, the sample can be collected in a fixed-point location for area sampling. Sample collection media is connected to the pump and placed onto the worker in the breathing zone. Personal sampling pumps are small and compact and are normally attached to the worker’s belt. Sample Collection Media including filters for particulates and sorbent sample tubes for gases/vapors.In general, active air sampling involves the use of 3 components:

These methods specify all pertinent details on how to collect a sample for designated compounds.

Sampling and Analytical Method manuals are published by government agencies such as U.S.

Trichloroethylene in degreasers for metal parts.

Formaldehyde in the medical and health services occupations, mortuary services, or paper mills.

Benzene, a known carcinogen, in petroleum products.

Carbon monoxide gas from poorly maintained engines or other equipment.

Mold spores from water intrusion eventsĮxposures to gases and vapors may include:.

Acid mists from electroplating operations.

Asbestos fibers in building materials, insulation, or brake linings.

Silica dust from sandblasting or cutting concrete.

Particulates include dusts, fibers, mists, fumes, smokes, or bioaerosols. In general, air contaminants can be present as a particulate or as a gas/vapor. In summary then we do air sampling for two reasons:Ģ.

All employers must ensure these allowable levels are maintained or receive citations and fines from the governmental regulatory authorities. These regulations specify allowable levels of designated airborne contaminants in the workplace. Therefore, government agencies have enacted regulations to ensure that workers are safe on the job. Ultimately, workers that are over-exposed can develop serious illnesses affecting target organs such as the lungs, kidneys, and liver. But workers in many industries throughout the world can be exposed to airborne contaminants that are more hazardous, at higher concentrations, and are a more frequent source of exposure.

In our normal lives, we all breathe in low levels of chemicals and other airborne contaminants from sources such as vehicle fuel and exhaust, cleaning supplies, and lawn care products.
