relied upon to demonstrate that the material is not capable of releasing AN in
airborne concentrations in excess of 1 part per million of air by volume (1
ppm) as an 8-hour time-weighted average, under the expected conditions of
processing, use, and handling which will cause the greatest possible release;
and
(C) Solid materials made from
and/or containing AN which will not be heated above 170° F during handling,
use, or processing.
(3)
An employer relying upon exemption under Section
5213(a)(2)(B)
shall maintain records of the objective data supporting that exemption, and of
the basis of the employer's reliance on the data, as provided in Section
5213(q).
(4) The requirements of this section are
subject to the provisions of the Occupational Carcingens Control Act of 1976
(Health and Safety Code, Division 20, Chapter 2).

Quantitative fit testing. A procedure using
sophisticated instrumentation which measures the concentration of a test agent
inside a respirator while worn in a test atmosphere of known concentration; the
ratio of the concentration of the agent in the test atmosphere to its
concentration inside the respirator provides a numerical value (the protection
factor) indicative of the degree of protection afforded the wearer by the
respirator.
(c) Exposure
Limits.
(1) Permissible Exposure
Limits--Inhalation.
(A) Time-Weighted Average
Limit (TWA). The employer shall assure that no employee is exposed to a
concentration in excess of 2 parts acrylonitrile per million parts of air by
volume (2 ppm) as an 8-hour time-weighted average.
(B) Ceiling Limit. The employer shall assure
that no employee is exposed to a concentration in excess of 10 parts
acrylonitrile per million parts of air by volume (10 ppm) as averaged over any
15-minute period during the working day.
(2) Dermal and Eye Exposure. The employer
shall assure that no employee is exposed to skin or eye contact with liquid
AN.
(d) Reporting of Use
and Emergencies. See section
5203.
(e) Exposure Monitoring.
(1) General. Determinations of exposure
levels shall be made from air samples that are representative of each
employee's exposure to AN over an 8-hour period. (For the purposes of this
subsection, employee exposure is that which would occur if the employee were
not using a respirator.)
(2)
Initial Monitoring. Within 30 days of the effective date of this standard (or
within 30 days of the introduction of AN into the workplace), each employer who
has a place of employment in which AN is present shall monitor each such
workplace and work operation to accurately determine the concentrations of
airborne AN to which employees may be exposed. Such monitoring may be done on a
representative basis, provided that the employer can demonstrate that these
determinations are representative of employee exposures.
NOTE: Monitoring conducted under the provisions of the
temporary emergency standard for AN may be relied upon to meet this initial
monitoring requirement.
(3)
Frequency.
(A) If the monitoring required by
this subsection reveals employee exposure to be below the action level, the
employer may discontinue monitoring for that employee.
(B) If the monitoring required by this
subsection reveals employee exposure to be at or above the action level but
below the permissible exposure limits, the employer shall repeat monitoring for
each such employee within three months. Quarterly measurements shall be
continued until at least two consecutive measurements taken at least 7 days
apart, are below the action level and thereafter monitoring may be discontinued
for that employee.
(C) If the
monitoring required by this subsection reveals employee exposure to be in
excess of the permissible exposure limits, the employer shall repeat these
determinations for each such employee at least monthly. The employer shall
continue these monthly measurements until at least two consecutive
measurements, taken at least seven (7) days apart, are below the permissible
exposure limits, and thereafter the employer shall monitor at least
quarterly.
(4) Additional
Monitoring. Whenever there has been a production, process, control, or
personnel change which may result in new or increased exposures to AN, or
whenever the employer has any reason to suspect a change which may result in
new or increased exposures to AN, additional monitoring which complies with
this subsection shall be conducted.
(5) Employee Notification.
(A) Within five (5) working days after the
receipt of monitoring results, the employer shall notify each employee in
writing of the results which represent that employee's exposure.
(B) Whenever the results indicate that the
representative employee exposure exceeds the permissible exposure limits, the
employer shall include in the written notice a statement that the permissible
exposure limits were exceeded and a description of the corrective action being
taken to reduce exposure to or below the permissible exposure
limits.
(6) Accuracy of
Measurement. The method of measurement shall be accurate, to a confidence level
of 95 percent, to within plus or minus 35 percent for concentrations of AN at
or above the permissible exposure limits, and to within plus or minus 50
percent for concentrations of AN below the permissible exposure
limits.
(f) Regulated
Areas.
