Signs on Trails with Naturally Occurring Asbestos

December 15, 2010

People using trails – especially OHV trails where a lot of dust can be generated – need to be aware of whether they may be exposed to naturally occurring asbestos (NOA).  Naturally occurring asbestos is already mapped in many places, so a desktop exercise could be performed to learn which trails intersect with known NOA.

Trails are normally posted with use and route information – The Sierra Fund recommends an easily recognizable icon or sticker to be added to already existing information.
