29 CFR 1910.1026(c): The employer did not ensure that employees were not exposed to an airborne concentration of chromium (VI) in excess of five micrograms per cubic meter of air (5ug/m3), calculated as an 8-hour time-weighted average (TWA):     (a) Denver Zoological Foundation, Special Projects Building, at 2900 E 23rd Ave, Denver, CO: On 2/21/19, the employer did not ensure that employees were not exposed to an airborne concentration of chromium (VI) in excess of 5ug/m3, calculated as an 8-hour TWA.  Employees performed MIG welding on stainless steel. This process generated chromium (VI) fume.  On 2/21/19 one employee was exposed to chromium (VI) at a concentration greater than the 8-hour TWA Permissible Exposure Limit (PEL) of 5 ug/m3.  The employee was exposed to chromium (VI) at a concentration of 6.26 ug/m3 as an 8-hour TWA.  This is 1.25 times the PEL.  Air monitoring was conducted for 390 minutes.

29 CFR 1910.1026(f)(1)(i): The employer did not implement engineering and work practice controls to reduce and maintain employee exposure to chromium (VI) at or below the PEL:  (a) Denver Zoological Foundation, Special Projects Building, at 2900 E 23rd Ave, Denver, CO: On and preceding 2/21/19, the employer did not implement engineering and work practice controls to reduce and maintain employee exposure to chromium (VI) at or below the PEL.  An employee performed MIG welding on stainless steel. This process generated chromium (VI) fume.  On 2/21/19 one employee was exposed to chromium (VI) at a concentration greater than the 8-hour TWA PEL of 5 ug/m3.  The employee was exposed to chromium (VI) at a concentration of 6.26 ug/m3 as an 8-hour TWA.  This is 1.25 times the PEL.  Air monitoring was conducted for 390 minutes.      Abatement Note:  Feasible engineering controls include, but are not limited to:  1.    Installation of local exhaust ventilation at the point of generation of the welding fume.   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):     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):     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):
