ESPI recommends the following good industrial hygiene practice which includes reducing airborne exposures to the lowest
feasible level for all constituents in this product. A leading scientific body recommending occupational standards is the American
Conference of Governmental Industrial Hygienists (ACGIH). The ACGIH recommends standards for all listed substances. The
ACGIH defines a threshold limit value (standards) as follows: “Threshold Limit Values refer to airborne concentrations of substances
and represent conditions under which it is believed that nearly all workers may be repeatedly exposed day after day without adverse
health effects.”
Because of wide variation in individual susceptibility, however, a small percentage of workers may experience discomfort
from some substances at concentrations at or below the threshold limit; a smaller percentage may be affected more seriously by
aggravation of a pre-existing condition or by development of an occupational illness. “Individuals may also be hyper-susceptible or
otherwise unusually responsive to some industrial chemicals because of genetic factors, age, personal habits (smoking, alcohol, or
other drugs), medication, or previous exposures. Such workers may not be adequately protected from adverse health effects from
certain chemicals at concentrations at or below the threshold limits.”
