Hello prospective laser user! Please read through this procedure and respond to the blue writing, then forward it to me via
email. Please also put a copy in your LASER notebook, thank you.
STANDARD OPERATING PROCEDURE
FOR THE put the
name and class of your laser here for ex. HE NE 3B LASER
OPERATED BY put your name here, & date
1.0 Prerequisites
1.1 Training
1.1.1 All persons who intend to operate a laser or who could be exposed to a hazardous laser beam or its reflection must receive documented CSULB Laser Safety Training from the Principle Investigator or the CSULB Laser Safety Officer.
1.1.2 Persons intending to operate a laser must receive training from the Principal Investigator or their designee, with respect to the safe operation of the particular laser. This training should be documented.
1.2 Medical Surveillance: Not required at this time.
2.0 Responsibilities
2.1 The Principal Investigator must:
ensure that all laser users receive adequate and appropriate
laser safety training prior to operating the laser(s). This training must include the review of the
CSULB Laser Safety Manual and the CSULB Laser Safety Training Document. This training must be documented. The PI
is also responsible for training laser users in the specific operation of
individual lasers; this training should be documented. Each student must have ready access to a
copy of the written operations guide.
ensure that all appropriate safety procedures are
followed, that any laser safety devices (interlocks etc.) are functioning
properly. Properly rated goggles must
be worn if the person could potentially be exposed to a hazardous beam or its
reflection.
determine the nominal
hazard zone of the laser . Safety
devices such as beam stops, wall blocks, interlocks etc. must be used whenever
possible to reduce the size of this zone.
supervise or otherwise ensure the adequate supervision of
users, visitors and service personnel as appropriate, and provide adequate
security to prevent unauthorized use.
correct and
control all laser equipment and laser
hazards as appropriate.
2.2 Laser users must:
be authorized and
trained appropriately to operate a potentially hazardous laser, or be in the presence of an operating,
potentially hazardous laser.
wear properly
rated goggles if she/he could be exposed to a hazardous beam or its reflection.
adhere to all
appropriate rules and procedures.
immediately
report accidents or potentially dangerous situations to the supervisor and/or
safety personnel. Common sense and
prudent practice must be considered at all times when operating a laser.
2.3 The Laser Safety Officer (LSO) is responsible for implementing the CSULB laser safety policies. Specifically, the LSO will be responsible for periodic safety review of laser facilities, performing basic laser safety training, evaluating protective equipment, and initiating corrective measures as necessary.
3.0 Protective Equipment
3.1 Protective eyewear which is appropriate for the power and wavelength(s) of the lasers in use must be worn in accordance with section 6.0 of this procedure.
3.2 A lab coat or other protective apparel should be worn by personnel if laser operations involve the emission of UV radiation.
3.3 A lab coat and fully enclosed chemical splash goggles will be worn at all times while working with chemicals that could injure the eyes or skin. Appropriate laser goggles shall be worn in lieu of chemical goggles when the potential exists for the eyes to be exposed to a hazardous beam or its reflection.
4.0 Alignment: Describe your alignment procedure. You need not include the safety features described below if they do not apply.
4.1 Appropriate security measures to restrict access to the laboratory should be effected to protect personnel not wearing protective equipment from exposure.
4.2 Assemble all needed items or tools to perform the alignment. Remember to keep objects off the table which may cause specular reflections.
4.3 The laser should be set to the lowest practical power while performing alignments.
4.4 Avoid working with the room lights off. Reducing the illumination in the room causes the pupils to dilate and increases the possibility of eye injury. The potential for electrical shock or other hazard also increases when vision is hampered.
4.5 Appropriate eye protection must be worn by persons performing alignments and persons present in an area where a direct or reflected source of laser light could come into contact with their eye.
4.6 Beam stops should be in place at locations where the beam may leave the table or stray off its intended path. If beam stops, enclosures or other safety devices were moved to perform an alignment, they must be replaced prior to operation.
4.7 Never look directly into the beam. If intra-beam viewing is required to align the beam, use a remote viewing camera.
4.8 In the case of invisible laser emissions, a visible low power laser should be used for the purposes of alignment wherever possible.
5.0 Engineering & Administrative
Controls
5.1 Engineering controls are interlocks or other physical restraints which limit the operation of the laser or impede access to the beam.
List applicable
engineering controls e.g. locks on lasers, beam is enclosed by a
plastic/metal/cardboard tube, laser is fastened to stationary base, laser is in
locked area etc.
5.2 Administrative controls are policies and procedures which laser users are obligated to comply with. Users must comply with policies and procedures described in this SOP.
List applicable administrative controls in addition to those described in this SOP e.g. only
faculty have keys, faculty send all students to Laser Safety Officer for
training prior to laser use, etc.
5.0 Operation
5.1 Set-up all necessary equipment for the experiment, with power off.
5.2 Start-up: Describe start-up procedure. If keys are used, include who has keys and where they are kept.
5.3 Procedural steps: Briefly (two to three paragraphs is typical) describe what you do during a typical experiment. Please give the actual hands on procedure, not the theory behind your experimentation.
5.4 Shut down: describe
