Health Hazard Evaluation Report HETA 91-287-2228, Ohio Department of Agriculture,Reynoldsburg Laboratory, Reynoldsburg, Ohio

摘要

In response to a confidential request from an employee at the Ohio Department ofAgriculture (SIC-8734) laboratory in Reynoldsburg, Ohio, an evaluation was undertaken of microbiological safety in the laboratory. Management subsequently requested an evaluation of noise exposures. The results of air sampling for sulfates did not reveal concentrations above the limit of detection. A major source of noise was identified as a Wellsaw and Stryker saw which are used to remove the spinal column, bisect skulls, or open the cranium of animals during necropsy. Both veterinarians wore ear muffs while sawing. Noise levels ranged from 93 to 98 decibels-A, but the sawing activities were of short duration. Noise from the ventilation system and noise in several other areas exceeded the recommended levels for laboratories where communication is necessary. During necropsy, total particulates were not above the limit of detection of the method. Questionnaires and interviews indicated that there was great deal of variability in the use of personal protective equipment, food and personal item storage, use of lab coats and home laundering of work clothes. The authors conclude that a potential hazard existed in the laboratory for the transmission of infectious organisms due to the lack of a comprehensive biological safety program. Improvements in laboratory ventilation were suggested for Building 3.
