[Jewelry making - Article 00202] - [Orchid] Respirator Hygiene

Good day,

    I write this as only a reminder that respirator hygiene can often be
    overlooked as days, weeks, and months go by. Yesterday, as do once a
    month, I cleaned my respirator with Dr. Bronners Peppermint Soap and
    changed the filters. I do a LOT of polishing and sanding, so I
    disassemble and clean the facepiece once a month and replace the
    filters. 

    This 3M 7502 half-face respirator and 3M 2047 pancake filters weigh
    in total only 5.5 ounces, so I can wear it all day. It is used for
    particulate protection. The pancake filters are fitted with a layer
    of charcoal for nuisance smells. If you have a cold, you might want
    to clean the facepiece more frequently. You'll notice that I put the
    date on the filter itself to remind me when they were last replaced. 

    You would follow the same procedure when using a chemical
    respirator. As always, read the manufacturers' instructions regarding
    filter application and exposure limits for that particular
    respirator. 

    Please try to be diligent in this practice as it WILL save your
    life. 

All the best,
