Our monitors are available in the form of “badges” that are worn by the employee during a sampling period. There’s no liquid or metal mechanics involved in our badge sampling, so the process is not cumbersome at all.
As for how the badge works, there is a microporous membrane that chemical vapors pass through. Under the membrane are special adsorbents that collect the vapors at a fixed rate. Our badges meet and exceed OSHA requirements, and OSHA/NIOSH validated methods are used in ACS’s AIHA-LAP, LLC-accredited laboratory.
Our badges:
- Cost less.
- Don’t need training.
- Don’t interfere with a worker’s activities.
- Test indoor air and personal exposure to toxic chemicals.
Here’s how personal exposure in the workplace is tested using our monitoring badges:
Step 1: Expose the badge
Workers clip the badge in or near a breathing zone, most likely on their person, to measure their personal exposure level to certain chemicals. Badges can be placed in rooms to measure the concentration of chemicals in the air. When clipped on a person, the badge is small and lightweight enough to not interfere with worker activities.
Step 2: Record Start Time and Stop Time
Record the requested information on the outside of the pouch that will enclose the badge after testing is complete. The required information includes the start time and stop time of testing.
Step 3: Return the Badge for Analysis
- Fast Turnaround Time
- Reliable Results
- Tested in an AIHA-LLP, LLC Accredited Laboratory
- The Lab is NY ELAP Accredited
When the test is finished, put the badge back into the pouch, make sure the ziplock is completely sealed, and mail it back to our lab for analysis. Our normal turnaround time is 72 hours after samples have been received. Some chemical analysis may take longer than 72 hours. Reports can be emailed, faxed, or mailed.
Workers can clip the badge near the breathing zone to measure person exposure level or place it in a room to measure area concentration. Badges are small and lightweight and do not obstruct the worker activities.
For Testing Indoor Air Quality or Area Monitoring
Simply leave the badge in the area for 24 hours.
To test indoor air quality of your lab, leave the badge in the area at least 5 ft off the floor for 24 hours. No need to hire expensive consultants.
