How to recognize medical signs and symptoms that may limit or prevent the effective use of the respirator; 7. What §1910.134 generally requires the employer to do under its Respiratory Protection Program. Employers may exclude from the Respiratory Program those employees who use a filtering facepiece type respirator in an atmosphere where no hazard exists. An employer whose employees are using any other type of respirator in an atmosphere where no respiratory hazard exists are required to be included in a Respiratory Program in accordance with §1910.134. An important provision in this rule allows employers whose employees are in an atmosphere containing hazardous gases or vapors to use air-purifying respirators only if the respirator is equipped with a NIOSH approved End-of-Service-Life-Indicator (ESLI) for the specific contaminant, or if the employer establishes a change schedule based upon objective information or data that will ensure that cartridges are changed before the end of their useful life. If neither an ESLI nor a change shedule is available, a supplied air respirator must be used. How to Select the Appropriate Respirator 29 CFR 1910.134 (d) “requires the employer to evaluate respiratory hazard in the workplace, identify relevant workplace and user factors, and base respirator selection on these factors.” To select the correct respirator, the employer must first identify the respiratory hazards in the workplace, and then: 1. estimate the employee’s exposure to the respiratory hazard(s), and 2. determine if the environment is immediately dangerous to life or health (IDLH). •All oxygen deficient atmospheres shall be considered IDLH with one exception: when an employer demonstrates that, under all foreseeable conditions, the oxygen concentration can be maintained within the ranges specified in the following table (for the altitudes set out in the table), then any North atmosphere supplying respirator(airline or SCBA) may be used - but no air-purifying respirator! •If an employer cannot identify or “reasonably estimate” the employee exposure, the atmosphere MUST be considered IDLH. Finally, the employer must 3. Identify the contaminant(s) present in the atmosphere and ask (and answer) the following questions: •What is the concentration? •Are they gaseous or particulate? •Are the contaminants IDLH? After following the preceding steps, the employer is ready to select the appropriate respirators for the particular hazard(s). If the atmosphere is IDLH, the employer must provide the following respirators for the employee: •A full facepiece NIOSH certified SCBA with a minimum service life of 30 minutes (e.g. North 800 Series), OR •A full facepiece pressure demand airline respirator with auxiliary self-contained air supply (e.g. North A8-85500A) If the atmosphere is NOT IDLH, the employer must provide a respirator to the employee that is appropriate for the contaminant(s) identified (concentration level, gaseous or particulate). For protection against gases and vapors, the following must be used: •An atmosphere-supplying respirator, OR •An air-purifying respirator where: 1. The respirator is equipped with a NIOSH certified ESLI for the contaminant, OR 2. If there is no ESLI available, a change schedule for cartridges that is based on objective information or data that ensures cartridges are changed before the end of their services life. For protection against particulates, the following must be use: •An atmosphere- supplying respirator, OR •An air-purifying respirator equipped with NIOSH certified filter for particulates under 42 CFR 84. In Canada, refer to Federal or Provincial Regulations and to CSA Z94.4 Standard for Respiratory Protection.
