Serious Gravity 10 3 instances 3 exposed
Issued
Abate by
Penalty
Initial $2800.00 · Current $0.00 Reduced
29 CFR 1926.55(a): Employee(s) were exposed to crystalline silica at concentrations above those specified in the Threshold Limit Values of Airborne Contaminants for 1970 of the American Conference of Governmental Industrial Hygienists:    (a) On or about August 27, 2012, an employee chipping concrete was exposed to respirable dust containing crystalline silica at an 8-hour time weighted average of 35.75 mppcf, approximately 1.64 times the calculated permissible exposure limit of 21.85 mppcf; this limit is established prevent silicosis. The sample was collected for 448 minutes; exposure calculations include a zero increment for the 32 minutes not sampled.     (b) On or about August 27, 2012, an employee chipping concrete was exposed to respirable dust containing crystalline silica at an 8-hour time weighted average of 36.32 mppcf, approximately 2.55 times the calculated permissible exposure limit of 14.2mppcf; this limit is established prevent silicosis. The sample was collected for 438 minutes; exposure calculations include a zero increment for the 42 minutes not sampled.     (c) On or about August 27, 2012, an employee chipping concrete was exposed to respirable dust containing crystalline silica at an 8-hour time weighted average of 46.99 mppcf, approximately 2.06 times the calculated permissible exposure limit of 22.8 mppcf; this limit is established prevent silicosis. The sample was collected for 438 minutes; exposure calculations include a zero increment for the 42 minutes not sampled.

Issued
Abate by
Penalty
Initial $0.00 · Current $0.00
29 CFR 1926.55(b): Feasible administrative or engineering controls were not implemented to reduce employee exposure(s) to crystalline silica:    (a) On or about August 27, 2012, an employee chipping concrete was exposed to respirable dust containing crystalline silica at an 8-hour time weighted average of 35.75 mppcf, approximately 1.64 times the calculated permissible exposure limit of 21.85 mppcf; this limit is established prevent silicosis. The sample was collected for 448 minutes; exposure calculations include a zero increment for the 32 minutes not sampled.     (b) On or about August 27, 2012, an employee chipping concrete was exposed to respirable dust containing crystalline silica at an 8-hour time weighted average of 36.32 mppcf, approximately 2.55 times the calculated permissible exposure limit of 14.2mppcf; this limit is established prevent silicosis. The sample was collected for 438 minutes; exposure calculations include a zero increment for the 42 minutes not sampled.     (c) On or about August 27, 2012, an employee chipping concrete was exposed to respirable dust containing crystalline silica at an 8-hour time weighted average of 46.99 mppcf, approximately 2.06 times the calculated permissible exposure limit of 22.8 mppcf; this limit is established prevent silicosis. The sample was collected for 438 minutes; exposure calculations include a zero increment for the 42 minutes not sampled.     Abatement normally will be multistep as follows:    STEP 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.    Abatement due 30 days from issuance date:    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 exposure to hazardous substance as referenced in this Citation.  This plan shall include, at a minimum, target dates for the following actions which must be consistent with the abatement dates required by this Citation:  1.  Evaluation of the extent and location of the hazard source.  2.  Evaluation of control measure option.  3.  Selection of optimum control measure(s).  4.  Ordering and delivery of equipment and materials.  5.  Installation of control measures.  6.  Training of employees in the proper operation and maintenance of the newly          implemented measures.  7.  Assurance of effective performance of control measures.  8.  All proposed control measures shall be approved for each particular use by a        competent industrial hygienist or other technically qualified person.    Abatement due 60 days from issuance date:    Step 3:  Abatement shall have been completed by the implementation of feasible engineering and/or administrative controls upon verification of their effectiveness in achieving compliance.
