A description of the proposed changes are as follows:
INDUSTRY SAFETY ORDERS
INFORMATIVE DIGEST OF PROPOSED ACTION/PLAIN ENGLISH OVERVIEW
Section 4322. Speed of Saw
Section 4322 states the arbor speed on circular saw blades or knives up to 22 inches in diameter shall not exceed 3600 rpm. On circular saws or knives with blades exceeding 22 inches in diameter, the manufacturers recommendations are to be followed. New language is proposed for the title of the regulation to read "Speed of Circular Saw Blades or Knives" to more accurately reflect the content of the regulation. Language pertaining to the arbor speed limit of 3600 rpm on saw blades or knives, and language specific to the diameter of saw blades are deleted in the proposal. New language is proposed that will permit circular saw blades or knives to be operated at speeds recommended by the manufacturer. Circular saws in use today operate at blade speeds between 2200 and 11000 rpm. The proposed amendment will permit the use of saws with blade speeds in the aforementioned rpm range that are already available on the market.
