case" conditions. All work shift personal sampling will be conducted in accordance with Cal- <br /> OSHA or NIOSH approved methods and procedures specific to the substance or physical hazard <br /> being monitored. In cases where methods are not available from Cal-OSHA or NIOSH, another <br /> nationally recognized industrial hygiene organization, such as the American Conference of <br /> Governmental Industrial Hygienists (ACGIH), will be consulted for reference. All sampling <br /> equipment will be maintained and calibrated in accordance with accepted methods or the <br /> manufacturer's recommendations. Samples requiring laboratory analysis will be submitted to <br /> qualified laboratories such as those accredited by the American Industrial Hygiene Association <br /> (AIHA). Sample preservation, quality control, and chain of custody procedures will be followed <br /> when transferring samples to the lab. <br /> Sampling Results <br /> Sampling results from direct reading instruments will be evaluated by a trained safety staff <br /> member. The safety member will develop an exposure estimate based on the results and the <br /> typical exposure time and determine the need for further work shift monitoring. The result from <br /> exposure estimates and actual work shift personal monitoring will, at a minimum, be compared to <br /> Cal-OSHA permissible exposure limits (PELs) to determine regulatory compliance. Results will <br /> also be compared to more restrictive standards, such as the ACGIH threshold limit values (TLVs) <br /> as a best practice. All sampling results will be documented using field notes, sampling forms, <br />' laboratory reports, and/or electronic databases. Documentation will typically include: <br /> • Work process monitored <br /> • Employee-partner(s) monitored <br /> • Frequency of exposure <br /> • Controls and/or personal protective equipment being used <br /> • Sampling date/time and duration <br /> • Monitoring equipment used in sampling <br /> Sampling results and interpretation will be communicated by safety staff to management at the <br /> location, who are then responsible for notifying affected employees. If the results pertain to an <br /> Cal-OSHA regulated substance, employees will be notified according to the procedures set forth <br /> in the applicable regulation. Sampling results will be used to identify areas for additional, more in- <br /> depth study, to select hazard controls, and to determine if existing controls are adequate. <br /> Program Review <br /> This industrial hygiene plan will be reviewed periodically by location management in consultation <br /> with Company IH/Safety staff and modified as needed to address changes in control measures, <br /> facilities, materials, and processes, or to respond to suspected or identified exposure hazards. <br /> ATTACH LOCATION SAMPLING PLAN <br /> 5 <br />
