ANOTHER STEP TOWARDS BETTER OCCUPATIONAL HEALTH AND SAFETY 12 #3500 ORGANIC VAPOR MONITOR NIOSH EVALUATION OF DIFFUSIONAL MONITORS We have been made aware that there is conflicting informa tion CIRCULATING ABOUT THE CURRENT TESTS BEING CONDUCTED BY NIOSH, ESPECIALLY CONCERNING THE PERFORMANCE OF THE OVM #3500. Because of the.- design of the test protocol, there are some test conditions under which all diffusion-type monitors will do badly. This stems from the choice of compounds and levels being tested. There are other test areas which will discriminate between the performance of individual monitors. AT THIS TIME, SPECIFIC INFORMATION IS NOT BEING RELEASED, AND WILL PROBABLY NOT BE RELEASED UNTIL THE END OF THE YEAR. Anything you may hear from the field is merely speculation. Rumors that the DuPont Pro-Tek would have some advantage if INCLUDED IN THE PRESENT TESTING ARE UNFOUNDED. MIM/FWS :tas giYI Occupational Health E.
