(2) To achieve compliance with subrule (1) of this rule, an employer shall ensure that administrative or engineering controls are implemented whenever feasible. If administrative or engineering controls are not feasible to achieve full compliance, then protective equipment or other protective measures must be used to keep the exposure of employees to air contaminants within the limits prescribed in this rule. Any equipment and technical measures used for this purpose must first be approved for each particular use by a competent industrial hygienist or other technically qualified person. Respirators must be used in a manner that is in compliance with Occupational Health Standard Part 451. “Respiratory Protection.” (3) General Industry Safety and Health Standard Part 302 “Vinyl Chloride,” applies to the exposure of every employee to vinyl chloride in every employment and place of employment covered by these rules in place of any different standard on exposure to vinyl chloride that would otherwise be applicable under subrule (1) of this rule. (4) The “Threshold Limit Values (TLV) of the American Conference of Governmental Industrial Hygienists (A.C.G.I.H.) for 1970” appear in R 325.60153 to R 325.60161. The Threshold Limit Values identified in these rules as Maximum Allowable Concentrations (MAC) are specified in these rules.
