Text For Citation: 01 Item/Group: 001B Hazard:

29 CFR 1910.1000(e): Feasible administrative or engineering controls were not determined and implemented to achieve compliance with the limits prescribed in 29 CFR 1910.1000(a) through (d): (a) Pine Flooring, LLC at 428 Vivian St., Longmont, CO: On and before April 14, 2019, the employer failed to implement an effective combination of engineering and administrative controls to reduce and maintain employee exposures to carbon monoxide to or below 50 ppm or less over an 8-Hour Time Weighted Averaged concentration. An employee, conducting assigned work tasks in a carpet cleaning van, was exposed to carbon monoxide at an 8-Hour Time Weighted Averaged concentration of 283.4 ppm, approximately 5.7 times the permissible exposure limit. Abatement Note: Feasible engineering controls include, but are not limited to: 1. Installation of local exhaust ventilation at the point of exhaust generation on the electrical generator in the van. 2. Use of general dilution ventilation in the van. 3. Evaluate the electrical generator for exhaust leaks and make repairs to ensure containment of exhaust. 4. Use of general ventilation may be adequate if the electrical generator was used outside the van or any confined spaces. Abatement Note: Abatement of this item will normally be multi-step as follows: 1. Effective respiratory protection shall be provided and used by exposed employees as an interim protective measure until feasible engineering and/or administrative controls can be implemented or whenever such controls fail to reduce employee exposure to within exposure limits. Only supplied-air respirators (SAR) and self-contained breathing apparatus (SCBA) are effective forms of respiratory protection for carbon monoxide. Continuous monitoring devices should be used to provide employees with methods to detect if they are being exposed to hazardous concentrations of carbon monoxide. STEP 1 ABATEMENT DATE (5 DAYS): June 14, 2019 2. Submit to the Area Director a written detailed plan of abatement outlining a schedule for the implementation of engineering and /or administrative measures to control employee exposures to the hazardous substance referenced in this citation. The plan shall include, at a minimum, target dates for the following actions which should be consistent with the dates required by this citation: a. Evaluation of the extent and location of the hazard source; b. Evaluation of control measure options; c. Selection of optimum control measures; d. Determination of control measure design; e. Ordering and delivery of equipment; f. Installation of control measures; g. Training of employees in proper operation and maintenance of newly implemented control measures; and h. Assurance of the effective performance of control measures. All proposed control measures shall be evaluated for each particular use by a competent Industrial Hygienist or other technically qualified person. Thirty day progress reports are required during the abatement period. The progress report must identify the action taken to achieve abatement and the date the action was taken. STEP 2 ABATEMENT DATE (15 DAYS): July 8, 2019 3. Abatement will be completed by the implementation of feasible engineering and/or administrative controls and upon verification of their effectiveness in achieving compliance. STEP 3 ABATEMENT DATE (30 DAYS): August 2, 2019
