Medical and Veterinary Laser Fumes

  1. 1. Medical & VeterinaryLaser ProceduresHazards of Laser FumesA presentation by© 2013 Sentry Air Systems, Inc.All Rights Reserved.
  2. 2. • The term “laser” stands for light amplificationby stimulated emission of radiation.• Ordinary light has many wavelengths andspreads in all directions. Laser light, on theother hand, has a specific wavelength.What are Lasers?Lasers focus in a narrow beam and create a very high-intensity light.
  3. 3. Types of LasersClassFDAClassIECLaser Product Hazard Product ExamplesI 1, 1M Considered non-hazardous. Hazard increases if viewed with opticalaids, including magnifiers, binoculars, or telescopes.•Laser printers•CD players•DVD playersIIa, II 2, 2M Hazard increases when viewed directly for long periods of time.Hazard increases if viewed with optical aids.•Bar code scannersIIIa 3R Depending on power and beam area, can be momentarily hazardouswhen directly viewed or when staring directly at the beam with anunaided eye. Risk of injury increases when viewed with optical aids.•Laser pointersIIIb 3B Immediate skin hazard from direct beam and immediate eye hazardwhen viewed directly.•Laser light show•Projectors•Industrial lasers•Research lasersIV 4 Immediate skin hazard and eye hazard from exposure to either thedirect or reflected beam; may also present a fire hazard.•Laser light show•Projectors•Industrial lasers•Research lasers•Lasers used to perform LASIK eye surgery
  4. 4. Laser Fumes or “Plumes”• A term used to refer to the “cloud” of contaminantscreated when there is an interaction between thebeam and the target matter.• These air contaminants are mostly associated withClass 3B and 4 lasers.• Ranges from metallic fumes and dust, to chemicalfumes and aerosols containing biologicalcontaminants.
  5. 5. Laser Fumes or “Plumes”• Examples include– Polycyclic aromatic hydrocarbons (from mode burns onpoly-type polymers)– Hydrogen cyanide and benzene (from cutting of aromaticpolyamide fibers)– Fused silica (from cutting quartz)– Heavy metals (from etching)– Benzene (from cutting polyvinyl chloride)– Cyanide, formaldehyde and synthetic and natural fibers(associated with other processes)

  7. 7. Hazards to Avoid• Laser Generated Airborne Contaminants (LGAC)– LGACs can form during disruption of tissue cells by heat (lasers,electrosurgical generators), mechanical manipulation (rotarydevices, saws), or ultrasonic instruments.– This disruption can cause the release of plume, which may containviable bacteria, viruses, cellular debris, particulates, noxious andtoxic aerosols, gases, vapors, or fumes.– Escherichia coli, Staphylococcus aureus, human papillomavirus,human immunodeficiency virus, and hepatitis B virus have beenfound in laser plume.– Many different chemicals have also been found in plume including,carbon monoxide, hydrogen sulfide, ammonia, toluene, styrene,phenol, benzyl cyanide, and hydrocyanic acid.
  8. 8. Preventative Measures• In general, there are three major controlmeasures available1. Filtered ventilation units2. Respiratory protection3. Isolation of the processSentry Air Systems designs and manufactures laser fume extractorsequipped with a variety of filters for your unique application.

  13. 13. Testimonial"I have a busy laser practice in Marylandand have been using the Sentry plumeextractor for nearly two years. The unit isquiet and efficient. The HEPA filter assuresme that we are using the most advancedtechnology available to ensure patient andstaff safety. I highly recommend this unitfor any medical practice that desires worryfree performance as an adjunct to theirlaser procedures."Dr. Mark E.
