Laser Principle and Safety - Desklib

This article discusses the hazards associated with laser operation, the adverse effects of laser plume inhalation, the mandatory information on entryway signs to laser rooms, and the Laser Safety Committee. It also provides a checklist of immediate actions to be taken in case of an incident. The article is relevant to healthcare service providers and users, and is useful for anyone interested in laser safety.

Week 7 and 8
Qa. 5 hazards associated with laser operation with example
The five laser operation hazards that has the potential to impose negative impact on
the patients includes electrical hazards, explosion hazards, compressed gasses hazards,
flammability hazards and hazards from laser generated air contaminants.
Hazard types Example
Electrical hazards Due to the usage of huge power supplies as well as repetitive pulsed laser, a
great risk of electric shock is there. This shock usually takes place when the
healthcare service users works with equipments that are not appropriately
grounded or posses a huge capacitor bank that has not been discharged.
Explosion hazards Due to the usage of high-pressure arc lamps, filament lamps, and capacitor
banks in laser equipment the second hazard takes place (Versteeg et al.,
2015). These items should be enclosed in housings that can endure the high
pressure resulting from exploding of these components.
Compressed gasses
hazards
The third hazard, that is compressed gases occurs since several lasers are
used that comprises hazardous gases like chlorine, fluorine, hydrogen
chloride, and hydrogen fluoride. Major example of this hazard includes free-
standing cylinder handling process that are not separated from the operators.
The inability to protect open cylinders from atmosphere and contaminants is
the major constrain in this situation (Flemming, 2015).
Flammability
hazards
When it comes to fire hazards, there prevails a good chance for a fire hazard
to happen with the class four lazar users. Fire accidents can takes place when
a class four laser is enclosed in a matter, which is exposed to irradiances.
Hazards from laser
generated air
contaminants
Finally, lazar generated air contaminants also known as cloud of
contaminants bears potential hazard both for the healthcare service providers
as well as healthcare service users. Some of the major example of air
contaminants includes a range from metallic fumes and dust, chemical
fumes, and aerosols containing biological contaminants (Versteeg et al.,
2015).

Qb. Likelihood of adverse effects resulting from laser plume inhalation
Laser plume can bear the potential hazard to both healthcare service users as well as health
care service providers. Direct exposure to laser plumes posses the potential to negetive
impact on the health of the same. Other workplaces where laser plumes inhalation causes
negative impact includes veterinary clinics, dental clinics, cosmetic treatment clinics,
laboratories and others. More than 29 percent of lazar associated healthcare issues includes
laser plumes issues. Healthcare symptoms that takes place from plume exposure involves
nose, eye as well as throat irritation. Currently, no further evidence of any long term as well
as short term health effects has been obtained . According to researchers, more and more
studies are required. However, hazardous materials like carcinogens, mutagens and irritants
have been found in laser plumes. Along with that, The human papilloma virus (HPV) DNA
and the human immunodeficiency virus (HIV) has also been found in the plume.
Qc.
Delegated to write the report: The laser operator is delegated to write the report
Needs to be notified about incident occurring: personnel who needs to be notified about
the report includes immediate supervisor, hazard recovery unit of the organization, ENT
medical team, the family of the health care service users.
Checklist of immediate actions:
Activity Checklist
1. Immediately pausing the operation
2. Reporting to the immediate
supervisors
