Text For Citation: 01 Item/Group: 015B Hazard: CHEMNEP

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)Hill Air Force Base, at 7290 Weiner Street, Hill Air Force Base, UT: On 3/3/11, Hill Air Force Base did not ensure that feasible administrative or engineering controls were determined and implemented to achieve compliance with the limits prescribed in 29 CFR 1910.1000(a) through (d). One employee abrasively blasted generators and small parts in Building 843B1. This process generated Particulates Not Otherwise Classified (iron oxide total dust). On 3/3/11 one employee was exposed to iron oxide total dust at a concentration greater than the 8 hour Time Weighted Average (TWA) Permissible Exposure Limit (PEL) of 15.00 mg/m3. The employee was exposed to iron oxide total dust at a concentration of 1373.07 mg/m3 as an 8 hour TWA. This is 91.54 times the PEL. Air monitoring was conducted for 265 minutes. (b)Hill Air Force Base, at 7290 Weiner Street, Hill Air Force Base, UT: On 3/3/11, Hill Air Force Base did not ensure that feasible administrative or engineering controls were determined and implemented to achieve compliance with the limits prescribed in 29 CFR 1910.1000(a) through (d). One employee abrasively blasted generators and small parts in Building 843B1. This process generated copper dust. On 3/3/11 one employee was exposed to copper dust at a concentration greater than the 8 hour Time Weighted Average (TWA) Permissible Exposure Limit (PEL) of 1.00 mg/m3. The employee was exposed to copper dust at a concentration of 1.578 mg/m3 as an 8 hour TWA. This is 1.58 times the PEL. Air monitoring was conducted for 265 minutes. Abatement Note: Abatement certification and documentation are required for this item (See enclosed "Sample Abatement-Certification Letter"). Abatement Note: Feasible engineering controls include, but are not limited to: 1.Use of abrasive blasting chamber, i.e., glove box, for small to medium sized parts. 2.Installation of local exhaust ventilation at the point of generation of the air contaminant. 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. STEP 1 ABATEMENT DATE (15 DAYS): August 15, 2011 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 (60 DAYS): September 29, 2011 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 (120 DAYS): November 28, 2011
