29 CFR 1910.95(b)(1): Employees were subjected to sound levels exceeding those listed in Table G-16 of Subpart G of 29 CFR 1910.95 and feasible administrative or engineering controls were not utilized to reduce sound levels: (a)Hill Air Force Base, at 7290 Weiner Street, Hill Air Force Base, UT: On 3/1/11, employees were subjected to sound levels exceeding those listed in Table G-16 of Subpart G of 29 CFR 1910.95 and feasible administrative or engineering controls were not utilized to reduce sound levels. On 3/1/11 one employee sanding aircraft parts in Building 238Q1 was exposed to noise at a dose in excess of the one hundred percent dose Permissible Exposure Limit (PEL). The employee was exposed to noise at a dose of 162.6 %. This is 1.62 times the PEL. The employer had not implemented engineering or administrative controls to reduce noise exposure to below the levels listed in Table G-16. This condition exposed the employee to a hazardous noise dose. (b)Hill Air Force Base, at 7290 Weiner Street, Hill Air Force Base, UT: On 3/1/11, employees were subjected to sound levels exceeding those listed in Table G-16 of Subpart G of 29 CFR 1910.95 and feasible administrative or engineering controls were not utilized to reduce sound levels. On 3/1/11 one employee abrasively blasting an aircraft in Building 275B2 was exposed to noise at a dose in excess of the one hundred percent dose Permissible Exposure Limit (PEL). The employee was exposed to noise at a dose of 442.7 %. This is 4.43 times the PEL. The employer had not implemented engineering or administrative controls to reduce noise exposure to below the levels listed in Table G-16. This condition exposed the employee to a hazardous noise dose. (c)Hill Air Force Base, at 7290 Weiner Street, Hill Air Force Base, UT: On 3/2/11, employees were subjected to sound levels exceeding those listed in Table G-16 of Subpart G of 29 CFR 1910.95 and feasible administrative or engineering controls were not utilized to reduce sound levels. On 3/2/11 one employee abrasively blasting aircraft parts in Building 220 was exposed to noise at a dose in excess of the one hundred percent dose Permissible Exposure Limit (PEL). The employee was exposed to noise at a dose of 179.9 %. This is 1.80 times the PEL. The employer had not implemented engineering or administrative controls to reduce noise exposure to below the levels listed in Table G-16. This condition exposed the employee to a hazardous noise dose. (d)Hill Air Force Base, at 7290 Weiner Street, Hill Air Force Base, UT: On 3/3/11, employees were subjected to sound levels exceeding those listed in Table G-16 of Subpart G of 29 CFR 1910.95 and feasible administrative or engineering controls were not utilized to reduce sound levels. On 3/3/11 one employee abrasively blasting aircraft parts in Building 507J4 was exposed to noise at a dose in excess of the one hundred percent dose Permissible Exposure Limit (PEL). The employee was exposed to noise at a dose of1116.0 %. This is 11.16 times the PEL. The employer had not implemented engineering or administrative controls to reduce noise exposure to below the levels listed in Table G-16. This condition exposed the employee to a hazardous noise dose. 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: A reduction in employee noise exposure would be considered significant if a three to five decibel noise level decrease is achieved (CPL 2-2.35A). 1)Reduce air pressure of the abrasive blasting equipment. 2)For small parts, perform the abrasive blasting in insulated blasting cabinets. Abatement Note: Abatement of this item will normally be multi-step as follows: STEP 1: Effective hearing 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. Hearing Conservation Program: 1)Employees working in, but not limited to, abrasive blasting or sanding shops are to be included in the existing Hearing Conservation Program. No additional costs anticipated. 2)Program to include all provisions required by OSHA Standards. 3)Costs associated with purchasing hearing protection are part of the existing PPE Program of the company. No additional costs anticipated. 4)Indirect costs include, but are not limited to, decreased production on audiometric testing day(s) and follow-up noise monitoring. STEP 1 ABATEMENT DATE (15 DAYS): August 15, 2011 STEP 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 industrial noise. The plan shall include, at a minimum, target dates for the following actions which should be consistent with the dates required by this citation: 1)Evaluation of the extent and location of the hazard source(s); 2)Evaluation of control measure options; 3)Selection of optimum control measures; 4)Determination of control measure design; 5)Ordering and delivery of equipment; 6)Installation of control measures;7)Training of employees in proper orientation and maintenance of newly implemented control measures; and 8)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 (30) 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 STEP 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
