Putting on a cartridge mask correctly is crucial for effective protection. First, ensure you have the correct cartridge for the specific hazard you're facing. Improper selection renders the mask useless.
Steps to Wearing a Cartridge Mask:
- Inspection: Before use, visually inspect the mask and cartridges for any damage. Replace if necessary.
- Placement: Hold the mask in front of your face, positioning it correctly over your nose and mouth.
- Straps: Secure the head straps, ensuring a snug but comfortable fit. Adjust straps until there are no gaps between the mask and your face. The reference material mentions pulling straps "far enough through the buckles to permit easy adjustment."
- Seal Check: Conduct a seal check by gently inhaling. The facepiece should collapse slightly, indicating a proper seal. If it doesn't, readjust the straps.
Important Considerations:
- Training: Proper training is essential. OSHA guidelines and resources emphasize the need for training on correct donning and use. [Source: http://www.osha.gov/publications/respiratory_protection_bulletin_2011]
- Cartridge Selection: Choose cartridges appropriate for the specific hazard. Using the wrong cartridges offers no protection. For example, a 3M 60926 cartridge is often cited as suitable, potentially even overkill, for certain resin and IPA fumes.

- Fit Testing: For critical applications, professional fit testing ensures a proper seal for maximum protection.
Remember, consulting the manufacturer's instructions for your specific mask model is crucial.
