29 CFR 1910.1000(e): To achieve compliance with paragraphs (a) through (d) of this section, administrative or engineering controls must first be determined and implemented whenever feasible. When such controls are not feasible to achieve full compliance, protective equipment or any other protective measures shall be used to keep the exposure of employees to air contaminants within the limits prescribed in this section. Any equipment and/or technical measures used for this purpose must be approved for each particular use by a competent industrial hygienist or other technically qualified person. Whenever respirators are used, their use shall comply with 1910.134. [71 FR 16673, April 3, 2006] On or about April 30, 2019, the employer did not implement sufficient engineering controls to keep the exposure of employees to below 50 ppm Carbon Monoxide during the work shift. An employee filling cracks and knot holes in lumber was exposed to 440% of the 8-hour Time Weighted Average Carbon Monoxide exposure limit of 50 ppm. The employee's calculated 8-hour Carbon Monoxide Time Weighted Average was 223.8 ppm.
