Washington – OSHA has published an amendment to correct typographical errors in the formulas in its final rule aimed at protecting workers from exposure to respirable crystalline silica.

The rule, which was released March 25 and went into effect June 23, establishes a new PEL of 50 micrograms of respirable crystalline silica per cubic meter of air.

According to the amendment, published in the Sept. 1 Federal Register, OSHA has corrected errors in formulas related to preceding permissible exposure limits for sectors and operations for which the new PEL does not apply “so they will appear as they did prior to publication of the final rule.”
