Waste anesthetic gases are found in medical, dental, and veterinary workplaces.  Employees should be monitored to determine exposure levels, and protect worker health.  For this badge, the collection media is 150 mg of activated carbon in a PTFE binder. 

The anesthetic gases are much more stable when toluene is used as the desorbtion solvent rather than carbon disulfide, as is used in OSHA 103.

The badge is the same as the 566 badge.  The only difference is in the labeling and analysis. Laboratories or customers using their own lab should order Item N566AT.

Tech Doc


Before sampling, ship and store at room temperature.

After sampling, store and ship at room temperature.  Return the samples to the lab for analysis within 14 days of sampling.

Use For

Sample during the time that the gas is in use.

Functional range: 30 minutes – 8 hours.  Minimum recommended sampling time is 30 minutes.

Regulatory Limits for Anesthetic Gases

Frequently, we are asked why there are no regulatory limits on our reports for two of the three most popular anesthetic gases:  Sevoflurane and Desflurane.  And for Isoflurane, we list a California OSHA limit.

Years ago, we used to quote the NIOSH recommendation of 2 ppm for all anesthetics.  In 2000, OSHA published a document about this issue.  (Anesthetic Gases: Guidelines for Workplace Exposures).  Unfortunately, the document specifically says:

  • At present, the Occupational Safety and Health Administration (OSHA) has no permissible exposure limits regulating these agents.


  • No NIOSH REL’s exist for the three most currently used anesthetics (isoflurane, desflurane, and sevoflurane.)

As far as we know, there is no further word from OSHA.  So, we no longer refer to the NIOSH recommendation on our reports.  However, until OSHA offers some leadership about this issue, we believe it wise to continue to use the 2 ppm recommendation.
