(1) Scope and application.
(a) This section applies to occupational exposure to 1,2-dibromo-3-chloropropane (DBCP).
(b) This section does not apply to:
(i) Exposure to DBCP which results solely from the application and use of DBCP as a pesticide; or
(ii) The storage, transportation, distribution or sale of DBCP in intact containers sealed in such a manner as to prevent exposure to DBCP vapors or liquids, except for the requirements of subsections (11), (16), and (17) of this section.
(2) Definitions applicable to this section:
(a) Authorized person. Any person specifically authorized by the employer and whose duties require the person to be present in areas where DBCP is present; and any person entering this area as a designated representative of employees exercising an opportunity to observe employee exposure monitoring.
(b) DBCP. 1,2-dibromo-3-chloropropane, Chemical Abstracts Service Registry Number 96-12-8, and includes all forms of DBCP.
(c) Director. The director of labor and industries, or his authorized representative.
(d) Emergency. Any occurrence such as, but not limited to equipment failure, rupture of containers, or failure of control equipment which may, or does, result in unexpected release of DBCP.
(3) Permissible exposure limits.
(a) Inhalation.
(i) Time-weighted average limit (TWA). The employer must ensure that no employee is exposed to an airborne concentration in excess of one part DBCP per billion part of air (ppb) as an eight-hour time-weighted average.
(ii) Ceiling limit. The employer must ensure that no employee is exposed to an airborne concentration in excess of five parts DBCP per billion parts of air (ppb) as averaged over any fifteen minutes during the working day.
(b) Dermal and eye exposure. The employer must ensure that no employee is exposed to eye or skin contact with DBCP.
(4) Notification of use. Within ten days of the effective date of this section or within ten days following the introduction of DBCP into the workplace, every employer who has a workplace where DBCP is present must report the following information to the director for each such workplace:
(a) The address and location of each workplace in which DBCP is present;
(b) A brief description of each process or operation which may result in employee exposure to DBCP;
(c) The number of employees engaged in each process or operation who may be exposed to DBCP and an estimate of the frequency and degree of exposure that occurs;
(d) A brief description of the employer's safety and health program as it relates to limitation of employee exposure to DBCP.
(5) Regulated areas. The employer must establish, within each place of employment, regulated areas wherever DBCP concentrations are in excess of the permissible exposure limit.
(a) The employer must limit access to regulated areas to authorized persons.
(b) All employees entering or working in a regulated area must wear respiratory protection in accordance with Table I.
(6) Exposure monitoring.
(a) General. Determinations of airborne exposure levels must be made from air samples that are representative of each employee's exposure to DBCP over an eight-hour period. (For the purposes of this section, employee exposure is that exposure which would occur if the employee were not using a respirator.)
(b) Initial. Each employer who has a place of employment in which DBCP is present must monitor each workplace and work operation to accurately determine the airborne concentrations of DBCP to which employees may be exposed.
(c) Frequency.
(i) If the monitoring required by this section reveals employee exposures to be below the permissible exposure limits, the employer must repeat these determinations at least quarterly.
(ii) If the monitoring required by this section reveals employee exposure to be in excess of the permissible exposure limits, the employer must repeat these determinations for each such employee at least monthly. The employer must continue these monthly determinations until at least two consecutive measurements, taken at least seven days apart, are below the permissible exposure limit, thereafter the employer must monitor at least quarterly.
(d) Additional. Whenever there has been a production process, control or personnel change which may result in any new or additional exposure to DBCP, or whenever the employer has any other reason to suspect a change which may result in new or additional exposure to DBCP, additional monitoring which complies with this subsection must be conducted.
(e) Employee notification.
(i) Within five working days after the receipt of monitoring results, the employer must notify each employee in writing of results which represent the employee's exposure.
(ii) Whenever the results indicate that employee exposure exceeds the permissible exposure limit, the employer must include in the written notice a statement that the permissible exposure limit was exceeded and a description of the corrective action being taken to reduce exposure to or below the permissible exposure limits.
(f) Accuracy of measurement. The method of measurement must be accurate, to a confidence level of ninety-five percent, to within plus or minus twenty-five percent for concentrations of DBCP at or above the permissible exposure limits.
(7) Methods of compliance.
(a) Priority of compliance methods. The employer must institute engineering and work practice controls to reduce and maintain employee exposures to DBCP at or below the permissible exposure limit, except to the extent that the employer establishes that such controls are not feasible. Where feasible engineering and work practice controls are not sufficient to reduce employee exposures to within the permissible exposure limit, the employer must nonetheless use them to reduce exposures to the lowest level achievable by these controls, and must supplement them by use of respiratory protection.
(b) Compliance program.
(i) The employer must establish and implement a written program to reduce employee exposure to DBCP to or below the permissible exposure limit solely by means of engineering and work practice controls as required by this section.
(ii) The written program must include a detailed schedule for development and implementation of the engineering and work practice controls. These plans must be revised at least every six months to reflect the current status of the program.
