Healthcare Health Hazards

January 30, 2018


hospital.jpgHospitals are wonderful concentrations of scientific disciplines that work together to diagnose, treat, heal, and cure a myriad of injuries and illnesses.  Unfortunately, this environment can expose the personnel providing these services to some health hazards of their own.  We have all heard about the infectious diseases (tuberculosis, etc.) and blood-borne pathogens (HIV, HBV, etc); but there are many more that are not patient-related. 

Industrial Hygiene is the science and art engaged in the anticipation, recognition, evaluation, and control of these other workplace health hazards.  In the healthcare setting these include, but are not limited to:

  • Ethylene oxide
  • Formaldehyde
  • Glutaraldehyde
  • Waste anesthetic gases
  • Anti-neoplastic drugs
  • Mercury
  • Latex allergy
  • and many more

Ethylene Oxide (EtO) is used within central supply as a sterilant for items that cannot be exposed to steam sterilization. Exposure usually results from improper aeration of the ethylene oxide chamber after the sterilizing process or poor gas-line connections.  Most hospitals concentrate their worry about EtO to the central sterilization area.  But it can also occur during off-gassing of sterilized items in outpatient surgery clinics, cardiac catheterization laboratories, operating rooms, dental labs, autopsy labs and other areas.  Periodic sampling in these other areas can help identify whether your EtO programs should be broader.

Formaldehyde is used as a fixative and is commonly found in most laboratories and the morgue.  Acute exposure to liquid and vapors can cause eye and respiratory irritation, while chronic exposure can cause laryngitis, bronchial pneumonia, and conjunctivitis. But most importantly, formaldehyde is a suspected carcinogen.  OSHA requires employers limit exposures to 0.75 ppm as an eight-hour time weighted average.  Since exposures are directly related to concentration of the solution, the duration of exposure, and the frequency of the task, all formaldehyde usage should be sampled occasionally.

Glutaraldehyde is used to disinfect heat-sensitive medical equipment in products such as Cidex, Sporicidin, and others. Glutaraldehyde is also used as a tissue fixative in histology and pathology labs and as a hardening agent in the development of x-rays.  It can irritate the mucous membranes and acts as a sensitizer. This means some workers will have strong reactions even if they are exposed to only small amounts. Workers may get sudden asthma attacks with difficult breathing, wheezing, coughing, and tightness in the chest.  OSHA does not regulate this chemical but the recommended limit of 0.05 ppm is a ceiling value that should not be exceeded during any part of the work shift.

This is a multi-part post that will be expanded on with additional health hazard examples in the coming weeks on our blog.
