Per OSHA’s April 2017 memo, the updated Silica standard* is enforceable as of September 23, 2017. You’ve got just over a month to comply if you weren’t ready by the previous deadline of June 23, 2017.
*the sampling analysis part of the standard is on track for enforcement June 23, 2018.
The construction standard for respirable crystalline silica is pretty “user friendly,” and is available here.
My recommended strategy for compliance is in the graphic below and I have a program template available for purchase by clicking on the graphic or here. The downloadable and customizable program template is $100 + one free hour of consultation via phone or in person within the Minneapolis, MN metro area.
