Subchapter 7. General Industry Safety Orders Group 16. Control of Hazardous
Substances Article 110. Regulated Carcinogens
§5212. 1,2 Dibromo-3-Chloropropane (DBCP).
(a) Scope and Application.
(1) This section establishes requirements for the control of employee exposure to 1,2-dibromo-3-chloropropane (DBCP).
(2) This section applies to the manufacture, reaction, release, packaging, storage, handling, disposal or other use of DBCP except as otherwise provided by this subsection.
(3) This section does not apply to exposures to DBCP which result from the application or use of DBCP as a pesticide. These exposures are governed by the California Department of Health Services for low level DBCP concentrations in water and the California Environmental Protection Agency for direct pesticide application or use.
(4) The storage, transportation, distribution or sale of DBCP in intact containers sealed in such a manner as to prevent the release of DBCP vapor or liquid are subject to the following provisions of this section:
(A) Notification of use and emergencies (subsection (d)).
(B) Emergency requirements (subsection (i)).
(C) Training (subsection (n)).
(D) Labeling requirements (subsection (o)(3)).
(5) The provisions of this section are subject to the requirements of the Occupational Carcinogens Control Act of 1976 (Health and Safety Code, Division 20, Chapter 2).
(1) Authorized person. Any employee or other person, specifically authorized by the employer whose duties require access to a regulated area including any employee or employee representative designated to observe the performance of monitoring and measuring procedures pursuant toCalifornia Administrative Code, Title 8, Section 340.1.
(2) Chief. The Chief of the Division of Occupational Safety and Health, P.O. Box 420603, San Francisco, California, 94142.
(3) DBCP. 1,2-Dibromo-3-chloropropane, Chemical Abstracts Service Registry Number 96-12-8, and includes all forms of DBCP.
(4) 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 an unexpected release of DBCP.
(c) Permissible Exposure Limit.
(1) Inhalation. The employer shall assure that no employee is exposed to a concentration of airborne DBCP in excess of 1 part DBCP per billion parts of air by volume (ppb) as an 8-hour time-weighted average (TWA).
(2) Dermal and Eye Exposure. The employer shall assure that no employee is exposed to eye or skin contact with DBCP.
(d) Notification of Use and Emergencies. See section 5203.
(e) Regulated Areas.
(1) The employer shall establish, within each place of employment, regulated areas wherever DBCP concentrations are in excess of the permissible exposure limit.
(2) Regulated areas shall be demarcated and segregated from the rest of the workplace in any manner that minimizes the number of persons potentially exposed to airborne DBCP. The posting of regulated areas shall be in conformance with Subsection (o) (2) (A).
(3) Access to regulated areas shall be restricted to authorized persons.
(f) Exposure Monitoring.
(A) Determinations of exposure levels shall be made from air samples that are representative of each employee's exposure to airborne DBCP over an 8-hour period.
(B) For the purpose of this paragraph, employee exposure is that exposure which would occur if the employee were not using a respirator.
(2) Initial. Each employer who has a place of employment in which DBCP is present, shall monitor each workplace and work operation to accurately determine the concentration of airborne DBCP to which employees may be exposed. Such monitoring shall be conducted as soon as possible but not latter than 30 days following the effective date of this section.
(A) If the monitoring required by this section reveals employee exposure to be below the permissible exposure limit, the employer shall repeat these measurements at least quarterly.
(B) If the monitoring required by this section reveals employee exposures to be in excess of the permissible exposure limit, the employer shall repeat these measurements for each such employee at least monthly. The employer shall continue monthly monitoring until at least two consecutive measurements, taken at least seven (7) days apart, are below the permissible exposure limit. Thereafter the employer shall monitor at least quarterly.
(4) 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 reason to suspect new or additional exposures to DBCP, the employer shall monitor the employees potentially affected by such change for the purpose of redetermining their exposure. Monitoring shall be conducted as soon as possible but not later than 30 days after the change.
(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 measurements which represent the employee's exposure.
(B) Whenever the results indicate that employee exposure exceeds the permissible exposure limit, the employer shall 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 limit.
(6) Accuracy of Measurement. The employer shall use a method of measurement which has an accuracy, to a confidence level of 95 percent, of not less than plus or minus 25 percent for concentrations of DBCP at or above the permissible exposure limit.
(g) Methods of Compliance.
(1) Priority of Compliance Methods. The employer shall 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 shall nonetheless use them to reduce exposures to the lowest level achievable by these controls, and shall supplement them by use of respiratory protection.
(2) Compliance Program.
(A) The employer shall establish and implement a written program to reduce employee exposures to DBCP to or below the permissible exposure limit solely by means of engineering and work practice controls as required by paragraph (g)(1). The program shall be established within 30 days of the effective date of the Order or within 30 days of the introduction of DBCP into the workplace.
(B) The written program shall include a detailed schedule for development and implementation of the engineering and work practice controls. These plans shall be revised at least every six months to reflect the current status of the program.
(C) Written plans for these compliance programs shall be submitted to the Chief upon request of authorized representatives of the Division of Occupational Safety and Health Administration and shall be available at the worksite for examination and copying by authorized representatives of the Division of Occupational Safety and Health Administration and any affected employee or designated representative of employees.
(D) The employer shall institute and maintain at least the controls described in his most recent written compliance program.

(C) Work operations for which feasible engineering and work practice controls are not yet sufficient to reduce exposure to or below the permissible exposure limit;
(2) Respirator program. The employer must implement a respiratory protection program in accordance with section 5144 (b) through (d) (except (d)(1)(C)), and (f) through (m).
(3) Respirator Selection.
