Editorial Policy

AsbestosHQ guides are written and reviewed by editorial staff using publicly available regulatory documents (EPA, OSHA, state environmental agencies), peer-reviewed research, and contractor and laboratory pricing data.

We disclose affiliate relationships at the top of every guide containing affiliate links. We earn commissions when readers purchase products through our links to Amazon Associates, EMSL Analytical, Schneider Laboratories, and other partners.

Affiliate relationships do not influence which products we recommend. We recommend the test kits, equipment, and laboratory services that match the use case described in the guide.

Corrections: We update guides when regulations change, prices shift materially, or readers identify factual errors. Corrections will be addressed in a future contact channel. We're setting that up now. Material corrections include a 'Last reviewed' date at the top of the guide.
