Hello all,

I am reaching out for advice regarding EPA Methylene chloride monitoring.  I work at 2YCC, where we use DCM less than 30 days per year, only for certain lab experiments. It’s likely that only two employees need to be monitored, but I am not quite sure if to perform monitoring only with badges or if we might need to invest in a direct reading equipment (“the owner or operator must provide measurements taken by direct-metering devices that give immediate results and provide sufficient information regarding potentially exposed persons”) if the latter, what equipment would you recommend for efficient direct reading?

I would really appreciate your support.

Thank you,
