AIR TESTING
|
- Summa canister, Tedlar bag, sorbent tube, cassette filter & liquid impinger sampling media can be provided by MAI.
- Soil gas, indoor air, ambient air, stack gases, gas cylinder purity (gases in gases), aerosols, air borne particulates & dissolved gases in water can be tested.
- Analytes include: Light & permanent gases, inert gases, biogenic gases, VOCs, TPH / fuels, metals & various organics groups. We are rapidly expanding our air testing capabilities & look forward to the challenge of adding new methods & analytes to serve our client’s needs.
- Excellent sensitivity, for example we can meet most indoor air & soil gas ESL limits for vapor intrusion risk assessment.
- Extended target lists for soil gas & indoor which include all ESL & ASGI volatile compounds
- Enforceable occupational health & safety limits for chemicals in air are issued by the following:
- OHSA PELs (Pemissable Exposure Limits)
- NIOH RELs (Recommended Exposure Limits)
- DFG (Germany) MAKs (Maximum Concentration Values)
- US DOE SCAPA TEELs (Temporary Emergency Exposure Limits for DOE sites only)
- Non-enforceable occupational health & safety limits for chemicals in air are issued by the following:
- ACGIH TLVs (Threshold Limit Values)
- SCAPA HBELs (Health-based Exposure Limits)
- OSHA & NIOSH limits are available at the CDC website, http://www.cdc.gov/niosh/ npg/npgsyn-a.html
