![]() These are fixed locations where RCS materials are being disturbed and control are not adequate to keep RCS below the PEL. Regulated area means an area, demarcated by the employer, where an employee’s exposure to airborne concentrations of respirable crystalline silica exceeds, or can reasonably be expected to exceed, the PEL. The data must reflect workplace conditions closely resembling or with a higher exposure potential than the processes, types of material, control methods, work practices, and environmental conditions in the employer’s current operations. Objective Data means information, such as air monitoring data from industry-wide surveys or calculations based on the composition of a substance, demonstrating employee exposure to Respirable Crystalline Silica associated with a particular product or material or a specific process, task, or activity. Permissible Exposure Limit (PEL) means the employer shall ensure that no employee is exposed to an airborne concentration of Respirable Crystalline Silica in excess of 50 μg/m3, calculated as an 8-hour TWA. The competent person must have the knowledge and ability necessary to fulfill the responsibilities set forth in this Exposure Control Plan.Īction Level, means a concentration of airborne Respirable Crystalline Silica of 25 μg/m3, calculated as an 8-hour TWA. SECM, Specified Exposure Control Methods: SECM outline work practices and personal protective equipment requirements for various tasks as outlined by OSHA.Ĭompetent Person, means an individual who is capable of identifying existing and foreseeable respirable crystalline silica hazards in the workplace and who has the authorization to take prompt corrective measures to eliminate or minimize them. RCS, Respirable Crystalline Silica: Silica dust that is composed of crystalline silica (quartz, Cristobalite, and/or Tridymite) small enough ( < 10 microns) to be inhaled into the respiratory system. ![]() ![]() PPE must be determined using the PPE Hazard Assessment form (include link to form or to PPE website) PPE, Personal Protective Equipment, PPE includes respirators, work gloves, hard hats, etc… SECM may require that respiratory protection be used for certain work tasks.
