(2) “f/cc” means fibres per cubic centimetre of air; “CAS” means Chemical Abstracts Service. (3) The numbers 1, 2 and 3 in the “Substance Interaction” column have the following meanings: 1 — substance may be readily absorbed through intact skin; 2 — substance is a simple asphyxiant that may create an atmosphere deficient in oxygen; available oxygen in the range of 19.5 percent to 23 percent by volume must be present; 3 — occupational exposure limit is based on irritation effects and its adjustment to compensate for unusual work schedules is not required. (4) A carcinogen is defined as “an agent capable of inducing benign or malignant neoplasms.” Based on the weight of evidence from epidemiologic studies, “A1” would be a Confirmed Human Carcinogen and means that the agent is carcinogenic to humans. “A2” would be a Suspected Human Carcinogen and means that human data are accepted as adequate in quality but are conflicting or insufficient to classify the agent as A1 (American Conference of Governmental Industrial Hygienists).
