The monitor sensors can be placed directly at nosecones or induction chamber lids where readings will be higher than the exposure at the investigator's breathing area, many inches away. Badge Analysis Badges are the monitoring method of choice for most facilities. The badge is clipped to the user's shirt collar where it adsorbs samples of the air near the breathing area. The badge is then sent to a laboratory for analysis and reporting. Frequency Monitoring via badges, air samples or real-time devices is not done daily or weekly.
Most facilities opt to have one person in each procedure area wear a badge once every six months.
You and your safety assessment committee may opt for more frequent monitoring if results exceed PEL's, procedure protocols change, if there is a change in personnel or equipment, or as needed.

Trace gas can occur due to leaking equipment, method of filling vaporizers, spillage, etc. It is assumed that prolonged and repetitive exposure to anesthetic gases can be toxic to procedure area personnel. However, the recommendation should be applied to these agents until updated recommendations are made.
