The first step is to be sure you have an OSHA compliant respirator program and then review the process for how the respirator cartridges and filters are being replaced in your workplace. This process should follow the principles outlined in OSHA Standard 29 CFR 1910.134.

The next step is to identify the contaminants in your workplace using one of these three methods:

Analysis of Existing Data: Review existing air monitoring data to understand contaminants in your workplace. If contaminants are not known, consult material safety data sheets (MSDS) for potential airborne hazards.

Workplace Environmental Analysis: Once potential contaminants are identified, 3M Diffusion and Detection Monitors can be used for certain gas or vapor contaminants to determine the average concentration level in the air.

Consultant Evaluation: Companies that specialize in contaminant evaluation can be found at www.aiha.org by selecting “Consultants Listing."

Based on the contaminants and concentrations documented in step two, the 3M™ Select and Service Life Software and Respirator Selection Guide (PDF , 416 KB) will help determine which respirator is recommended for a given exposure situation. It includes data on 800+ chemicals, including gases, vapors and particulates.

The cartridge and filter replacement plan implements a process that helps employees replace their cartridges and filters at the appropriate time. To help establish how frequently cartridges should be replaced, visit 3M™ Select and Service Life Software.

Ongoing record keeping is important for ensuring long-term compliance to the replacement schedule. It also assists in purchasing and inventory management. This record-keeping template can help you collect and maintain all the necessary information.
