On January 19, 2018, OSHA issued a citation to Spirit Aerosystems, Inc., alleging one willful and five serious violations of the OSHA hexavalent chromium standard (29 CFR 1910.1026) and assessing $194,006 in penalties.
In the citation, OSHA alleges that the manufacturer of aerostructures (including portions of fuselages) willfully failed to prevent employee exposures to levels above the permissible exposure limit (PEL) of 5.0 ug/m3 8 hour time weighted average (TWA) and to implement feasible engineering and work practice controls “to reduce employee exposure to the lowest achievable level.” The citation notes an employee who was sanding and grinding was exposed to hexavalent chromium at 9.0 ug/m3 on a time weighted average, 1.8 times the PEL.
The citation further alleges that Spirit Aerosystems did not perform periodic monitoring every three months, did not perform monitoring when process changed, did not demarcate a regulated area for hex chrome, allowed employees to leave the hex chrome work area without removing contaminated clothing and equipment, and did not adequately train employees regarding the OSHA hex chrome standard.
The citation is notable for several reasons. First, it is an indication that OSHA is still actively enforcing the hex chrome standard. Second, it underscores OSHA’s position that an increased scheduled work load is a process change that would require additional exposure monitoring. Third, it affirms that the aircraft painting exception, which establishes a 25 ug/m3 exposure limit, does not apply to grinding and sanding operations. Finally, it raises questions about how far an employer has to go to reduce exposures—does the employer’s obligation to implement controls require it to reduce exposure “to the lowest achievable level” as alleged in the citation or does the employer meet its obligation if it reduces exposure to the PEL?
