What this inspection record means

OSHA opens inspections for many reasons: routine scheduling under a national or local emphasis program, an employee complaint or referral, or a follow-up after a reported injury. Opening or conducting an inspection is not itself an allegation or a finding that this employer broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

29 CFR 1910.132(a): Protective equipment was not used when necessary whenever hazards capable of causing injury and impairment were encountered:    a)  On or about September 3, 2014, and at times prior, employees were exposed to fall hazards of greater than 10 feet when they stood on tanker trucks at the sodium hydrosulfide loading station without adequate personal protective equipment that would prevent them from falling.    b)  On or about September 3, 2014, and at times prior, employees were exposed to fall hazards of greater than 10 feet when they stood on railcars at the sodium hydrosulfide loading station without adequate personal protective equipment that would prevent them from falling.    c)  On or about September 3, 2014, and at times prior, employees were exposed to fall hazards of greater than 10 feet when they stood on tanker trucks at the SS1 asphalt loading station without adequate personal protective equipment that would prevent them from falling.      Or, in the alternative:      29 CFR 1910.23(c)(1):  Open-sided floors and/or platforms four feet or more above adjacent floor or ground level were not guarded with standard railings (or equivalent) and toeboards:      a)  On or about September 3, 2014, and at times prior, employees were exposed to fall hazards of greater than 10 feet when they stood on tanker trucks at the sodium hydrosulfide loading station because the platform on the truck was not equipped with standard railings.  A top rail did exist, but the rail system was missing a standard mid rail.      b)  On or about September 3, 2014, and at times prior, employees were exposed to fall hazards of greater than 10 feet when they stood on railcars at the sodium hydrosulfide loading station because the platform on the rail car was not equipped with standard railings.  One rail did exist around most of the platform, but the rail system did not have the standard top and mid rail.      c)  On or about September 3, 2014, and at times prior, employees were exposed to fall hazards of greater than 10 feet when they stood on tanker trucks at the SS1 asphalt loading station because the platform on the truck was not equipped with standard railings.

29 CFR 1910.134(d)(1)(i): The employer did not select and provide an appropriate respirator based on the respiratory hazard(s) to which the worker was exposed and user factors that affect respirator performance and reliability:    a.  On or about August 27, 2014, and at times prior, employees loading truck and rail tankers with sodium hydrosulfide were exposed to hydrogen sulfide at greater than the maximum peak (50 parts per million) above the acceptable ceiling concentration of 20 parts per million because the employer did not ensure that respirators appropriate for the hazardous atmosphere were worn by employees:    1.  On or about August 27, 2014, one employee was exposed to 200 parts per million or greater of hydrogen sulfide while he loaded a tanker truck with sodium hydrosulfide.       2.
