CHAPTER II: ILLINOIS EMERGENCY MANAGEMENT AGENCY
SUBCHAPTER b: RADIATION PROTECTION
PART 315
STANDARDS FOR PROTECTION AGAINST LASER RADIATION
SECTION 315.APPENDIX A SAMPLE STANDARD OPERATING PROCEDURES
Section 315.APPENDIX A Sample
Standard Operating Procedures
Standard Operating Procedures
(SOPs) are governed by institutional policy and are developed, modified and
maintained in accordance with the needs of individual facilities. Information
relative to safety incorporated into these SOPs is gathered from a wide range
of resources, including, but not limited to, the laser system manufacturer or
distributor. This Appendix A contains examples of SOPs for issues associated
with the use of laser systems. It is recognized that the safety needs of
installations with multiple laser systems may be different from those
facilities with a single laser system. The samples that follow cannot cover
all situations or procedures; they are only intended as models that should be
used to accommodate specific requirements. Typically, the Laser Safety Officer
shall have the responsibility to see that SOPs are followed.
It is reasonable to expect that
the manufacturer of the laser system shall supply safety information that can
serve as the cornerstone for the generation of the SOPs. It is incumbent upon
the operator to demand the information from the manufacturer. The availability
of safety related information is facilitated by the FDA requirement that the
manufacturer of laser products provide the user with adequate instructions for
the safe operation and maintenance of all laser products.
SAMPLE 1: Controlled Access
to the Laser Room
Purpose: To define the
area in which control measures shall be applied and to describe the control
measures necessary in order to maintain a safe environment for use of the laser
system.
Policy: Class 3b and
Class 4 lasers shall be operated in areas where traffic flow and compliance
with all safety procedures can be monitored.
Procedure:
1) Appropriate warning signs shall be posted at eye level on all
doors that access a room where a laser is to be operated. These signs shall
state all required information and shall be removed when the laser is not in
use.
2) Safety goggles labeled with the appropriate wavelength and
optical density shall be available at the entry where each door sign is posted.
3) Glass windows shall be covered with shades or filters of
appropriate optical density whenever a fiberoptic laser system is operational.
4) All safety procedures shall be followed during service,
maintenance and demonstrations.
5) No one shall be allowed into a laser room unless properly
authorized and protected.
6) The laser shall not be activated when it is necessary to open
the door, if the controlled area extends to the doorway.
7) Laser keys shall be kept in a secured area and signed out only
by those authorized to do so.
SAMPLE 2: Ocular Safety
Purpose: To prevent
ocular injuries to personnel working with Class 3b and Class 4 lasers.
Policy: Within the
controlled area, all personnel shall adhere to appropriate eye protection
procedures during all laser applications.
NOTE: Under some conditions,
the controlled area may include the entire room in which the laser procedure is
performed. Under those conditions, the ocular safety procedures listed in this
Sample 2 apply to the entire room. In health care facilities, ocular safety
procedures shall also apply to the patient receiving laser treatment.
All personnel involved in
maintenance and demonstrations of laser systems shall follow all ocular safety
procedures whenever a laser is in operation in the facility.
Procedure:
1) Appropriate eyewear shall be worn by everyone in the
controlled area while the laser is in operation. Appropriate eyewear consists
of glasses or goggles of sufficient optical density to prevent ocular damage at
the laser wavelength in use. Exception to this is the operator looking through
an attached microscope with a lens that has the appropriate optical density for
the laser in use.
2) Prior to use, the operator and ancillary personnel shall be
responsible for selecting and examining eyewear for comfort, proper fit, and
presence of labels describing both wavelength and proper optical density.
3) If eyewear is damaged, it shall not be worn and a report shall
be made to the laser safety officer.
4) Contact lenses are not acceptable as protective eyewear.
Prescription lens wearers shall use appropriate laser safety eyewear.
5) All goggles shall have side shields to protect from peripheral
injury and impact.
6) Any articulated arm that is not shuttered shall be capped when
not connected to the hand piece or the operating microscope.
7) The laser system shall be placed in standby mode when delivery
optics are moved away from the target.
8) In health care facilities, patients shall be fitted with
appropriately labeled eyewear, or have their eyes covered with wet cloth pads
or towels. Metal or dry materials shall be placed on the patient's face or
eyes only when indicated.
SAMPLE 3: Handling of Laser
Fiber Delivery Systems in Health Care Facilities
Purpose: To promote safe
and proper handling of laser fiber delivery systems and to limit the potential
for fiber breakage, damage and reduced efficiency during clinical laser
procedures.
Policy: Personnel
handling laser fibers shall assure compliance with all safety procedures and
shall consider the fiber an extension of the laser system, governed by
applicable standards and regulations.
Procedure:
1) Appropriate eye safety filters shall be used with
endo/microscopes.
2) Laser room windows shall be covered completely with
appropriate filters, if necessary.
3) Fibers and associated equipment shall be positioned to allow
for safe traffic patterns in the room.
4) The fiber shall be examined for breaks or damage of the distal
tip, the proximal connector and the catheter sheath. Fiber shall be calibrated
in accordance with manufacturer's directions. If deficiencies or damage are
noted, another fiber shall be obtained.
5) Do not use clamps or other instruments to secure fiber in the
operative site.
6) Always use coaxial cooling that is appropriate to the
procedure. Never use gas to purge a fiber in the intrauterine cavity.
7) Never operate the laser unless the aiming beam (if used) and
the tip of the fiber beyond the end of the endoscope are both visible.
8) Monitor the fiber for distortion of the beam, decreased power
transmission and accumulation of debris on the tip.
9) Never reuse a disposable fiber without manufacturer's
directions.
10) Always put the laser in standby when not aimed at a target.
SAMPLE 4: Non-Beam Hazards
in Health Care Facilities
Purpose: To recognize
and effectively deal with a variety of potential non-beam hazards that may be
present during laser procedures.
Policy: Non-beam hazards
are the purview of safety and industrial hygiene personnel, who will effect the
appropriate hazard evaluation and control.
Procedure:
I. Fire
1) Never use alcohol in the operative field. Fibers may be
rinsed in hydrogen peroxide or saline intraoperatively.
2) Never place a hot fiber directly on paper drapes. Wait until
tip is cool before contact is made with flammable material.
3) Use fire-retardant drapes, damp packs or pads. Fill pelvic
cavity with Ringer's, saline or other appropriate solution during surgery.
4) Put laser system in standby mode when procedure is interrupted
or terminated.
5) Avoid high levels of oxygen in the operative field.
6) Avoid laser beam exposure of the sheaths of flexible fiber
endoscopes, since many of the sheaths are flammable.
II. Plume Management
1) Remove laser generated airborne contaminants from the laser
target area to reduce the transmission of potentially hazardous particles.
2) Position smoke evacuator in the operating room whenever a
plume is anticipated.
3) Check operation of the plume management system prior to the
beginning of a procedure.
4) Check the plume filter monitor and, if needed, install a clean
filter.
5) In-line filters with minimum 0.3 μm filtration shall be
placed between wall suction and the fluid canister for:
a) Suction line not connected to evacuator
b) Procedures producing minimal plume
c) Failure of evacuator before or during operation
6) Distal collection port shall be no more than 2 cm from impact
site when practical.
7) All tubing, connectors, adaptors and wands will be changed
between patients and disposed of according to biohazard procedures.
III. Electrical Shock
1) During service or maintenance, precautions shall be taken
against electrical shock that may be fatal.
2) Medical lasers shall be installed and operated in conformity
with the National Electrical Code.
SAMPLE 5: Work Practices for
Optical Fiber Communications Systems (OFCS)
Purpose: To recognize
and effectively deal with a variety of potential hazards that may be present
when working on an OFCS.
Policy: Engineering
controls shall not take the place of good work practices. Good work practices
are essential to operating, servicing and maintaining OFCS, especially with
higher power systems that utilize Class 3b and Class 4 lasers.
Procedure: The following
presents some basic guidelines when working on any OFCS.
1) Trained Personnel. Only authorized, trained personnel shall
be permitted to install or perform service on OFCS containing Class 3b or Class
4 lasers.
2) Unterminated Fibers
a) Do not view the end of a fiber with unprotected eye. Fiber
should only be viewed with an indirect image converter or with a filtered
optical instrument or optical density (OD) sufficient to reduce the exposure to
levels below the appropriate MPE.
b) Always cover the ends of unterminated fibers with a splice
protector, tape or end caps.
3) Splicing. Splicing on ribbon cables, fixed array cables or
OFCS containing Class 3b or Class 4 lasers shall be de-energized or viewing
systems incorporating personal protection shall be employed.
4) Installation and Testing. The laser source shall be first to
be disconnected and last to be connected when installing and/or testing an
OFCS.
5) Modifications. No modifications shall be made to the OFCS or
associated equipment without management or supervision authorizations. Such
modifications may alter the service group classification of the OFCS.
6) Labels. Any damaged or missing optical safety labels shall be
reported immediately to the supervisor.
7) Other Hazards
a) Use of protective guards or shields shall be used during
splicing and cleaving operation to prevent direct injury from small lengths or
particles of fiber. Proper disposal of fiber pieces avoids subsequent
embedding in clothing or skin.
b) Optical photocuring may present a UV or light source hazard.
Protective filter lenses of the appropriate optical density shall be worn if
viewing of the light source is probable.

GENERAL
NOTES:
|
1.
|
The MPE for diffuse
reflections at wave lengths between 0.400 and 1.400 μm is obtained by
multiplying the corresponding MPEs above by CE (see Section
315.Table C for correction factors and T1).
|
|
|

For repeated (pulsed)
exposures, see ANSI Z136.1.

NOTES:
|
1.
|
These apertures are used for
the measurement of optical power or energy for purposes of laser
classification
|
|
|
|
|
|
|
2.
|
When the laser output is
intended to be viewed with optics (excluding ordinary eyeglasses) or the
laser safety officer determines that there is reasonable probability of
accidental viewing with optics, a 50 mm aperture is used if the following
conditions are met.
|
|
|
|
|
|
|
A)
|
Viewing with optics presents a
more severe hazard than unaided viewing.
|
|
|
|
|
|
|
B)
|
The viewing time is sufficient
to constitute a hazard.
|
|
|
|
|
|
|
3.
|
Under normal conditions these
exposure durations would not be used for classification (see ANSI Z136.1
(Table 9)).
