Inhaling air containing PAHs

Malignant neoplasm of the bladder - Inhaling air containing PAHs Factor

RMA definition

Polycyclic aromatic hydrocarbons (PAHs) are hydrocarbons with three or more condensed aromatic rings in which certain carbon atoms are common to two or three rings. A common example is benzo[a]pyrene. Polycyclic aromatic hydrocarbons occur in crude oil, shale oil, and coal tars, and can be formed during the combustion of organic material or during high temperature processing of crude oil, coal, coke, or other industrial carbon compounds.

SOP Requirements

For the purposes of the SOP the minimum concentration of PAHs in the air must be 0.2mg/m³.  This is a very high concentration level well beyond that which would be permissible under normal workplace health and safety provisions.  Such concentrations would result in visible pollution and might occasionally occur, for example, within an enclosed vehicle workshop, when diesel exhaust fumes leak into a closed APC, or as a result of the oil fires during the first Gulf War.
