OSHA citations for flash fire and exposure hazards of toluene ($183K)

OSHA has cited a carpet restoration, plumbing, and resurfacing contractor for exposing employees to safety and health hazards after a fatal incident at a worksite. The company faces $183,127 in penalties.  OSHA initiated an investigation after an employee suffered fatal injuries after inhaling lacquer thinner, which was used to resurface a bathtub. OSHA cited the company for

  • failing to evaluate the chemical wash cleaning task and determine workers’ level of exposure to the lacquer thinner
  • improperly labeling mixtures used to clean and resurface bathtubs and countertops
  • exposing employees to a concentration of toluene several times above permissible exposure limits
  • allowing flash fire and explosion hazards
  • failing to provide suitable facilities for quick drenching and flushing of the eyes and body 
  • flame retardant clothing
  • not performing a personal protective equipment assessment
  • using respirators properly

However, other methods of abatement may be equally, or more appropriate. The ultimate responsibility for determining the most appropriate abatement method rests with the employer given its superior knowledge of the specific conditions at its worksite.

Abatement Schedule

Step 1 – A written detailed plan of abatement shall be submitted to the Area Director outlining a schedule for the implementation of engineering and/or administrative measures to control employee exposures to hazardous substances 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 engineering/administrative control options;

(2) Selection of optimum control methods and completion of design;

(3) Procurement, installation and operation of selected control measures;

(4) Testing and acceptance or modification/redesign of controls.

All proposed control measures shall be approved for each particular use by a competent industrial hygienist or other technically qualified person. 90-day progress rep01is are required during the abatement period.

Step 2: Abatement shall have been completed by the implementation of feasible engineering and /or administrative controls upon verification of their effectiveness in achieving compliance.
