5. Cleaning and Maintenance

5.4.1 Replacing the prefilter

The prefilter bag must be changed after every 10,000 - 15,000 cassettes - de­pending on the type of laser printing (positive or inverted) - or 1x a year.
If the laser printer detects a reduction of the air flow rate, an audible signal is sounded by the filter unit and you see the following message on the monitor.
When either condition (warning or beeping) is present the user must change the prefilter bag.
In the case of the warning, click OK on the warning massage window after you have changed the filter to reset the counter back to zero. If you click the Cancel button, the window is closed, but the window reappears after the next cassette is printed.

2. Then tilt the tube end on the cover towards the metal plate to ensure
secure closing.
3. Make sure that the prefilter bag does not get crushed between the plas­tic cover and the metal plate and become damaged.
· This causes the filter to lose vacuum and releases harmful dust particles.
Do not operate the LP C Laser Cassette Printer without ensuring that the filter unit is properly connected and running. Other­wise, the instrument will malfunction and expel harmful dust particles.

5.4.2 Replacing the main filter

The main filter must be replaced once a year or after printing 100,000- 120,000 LPC cassettes, or if the following message appears on the monitor.

7.1 Laser hazard classes

The intent of laser hazard classification is to provide clear distinction of the lasers’ properties and hazards to users so appropriate protective measures can be taken. Classification is based on the maximum output available for the intended use. Specific labeling requirements indicate that the class of the laser as well as the emission wavelength(s) and any other applicable precaution­ary instructions must be included on any signage. Laser classification is also used for determin­ing requirements for medical surveillance for those individuals working with and around lasers.
The US standard for laser safety [21 CFR 1040.10], the ANSI standard [ANSI Z136.1] and the inter­national standard [EN 60825] classify lasers into five different hazard categories. These classes are based upon the combination of wavelength range, power, and emission duration, which are used to determine the level of risk and the potential to cause biological damage to the eye or skin.
The definitions compiled from ANSI Z136.1 are as follows: The Leica LPC Laser Cassette Printer, Model LPC is rated as follows:
CLASS 1 laser product using a CLASS 4 (5 W, 10.57 – 10.63 µm)
embedded laser
38
Class 1:
Any laser, or laser system containing a laser, with wavelength ranges from Ultraviolet through Far Infrared (180 nm – 100,000 nm +), that cannot emit laser radiation levels exceeding Class 1 Accessible Emission Limits (AEL) as defined by ANSI Z136.1. For example this would compute to exposure (for a 48-hour period) for a 488 nm laser of no greater than 0.2 mW. Basically, the laser radiation level emitted by a device classified as Class 1 produces no haz­ard whatsoever to the user during normal operation. Presently, Class 1 lasers and laser sys­tems are exempt from all control measures. The Class 1 designation does not apply during times of maintenance or service where the safety controls of the device are defeated or otherwise removed. The Class 1 environment resumes once the device is returned to its orig­inal state with all safety devices properly reconnected.
Operating Manual V 1.0 – 06/2010
7. Appendix A – Laser Safety
••
Class 2:
••
This classification applies only to continuous wave (CW) and repetitive-pulse lasers and laser systems of the visible part of the electromagnetic spectrum (400 – 700 nm) that exceed Class 1 levels, but do not exceed an average radiant power of 1 mW.
••
Class 3a:
••
Lasers and laser systems that have an accessible output between one and five times the Class 1 AEL for wavelengths shorter than 400 nm or longer than 700 nm, or less than five times the Class 2 AEL for wavelengths between 400 and 700 nm. Lasers of this class have intermediate power ranges of 1 - 5 mW.
••
Class 3b:
••
Lasers and laser systems having the power range between 5 - 500 mW. This applies to la­sers with wavelength ranges from Ultraviolet through Far Infrared (180 nm – 100,000 nm +). These lasers or laser systems can produce a hazard if viewed directly, and may produce an eye hazard when viewing diffuse reflections off of a shiny surface at angles of less than 5 degrees from the source, however Class 3b lasers should not produce a hazardous diffuse reflection from a matte (not shiny) surface.
••
Class 4:
••
Lasers and laser systems having power greater than 500 mW. This applies to lasers with wavelength ranges from Ultraviolet through Far Infrared (180 nm – 100,000 nm +). This class of laser poses the greatest hazard, and any and all precautions should be taken to protect oneself from exposure to direct or diffuse laser radiation. Direct exposure to the eye from this class of laser can cause permanent damage. Stray beams are potential fire hazards and combustible material should be kept out of beam paths at all times.
Leica LPC
ANSI Z136.1 requires specific control measures for each laser classification and the en­vironment in which they are used. The chart above lists some of the requirements that may need to be implemented in a laboratory setting. The Biosystems Laser Safety Offic­er, or designee, should reference the applicable safety regulations for appropriate con­trol measures to implement in the area the instrument will be used.

7.3 Biological effects of laser beams

7.3.1 Eye injuries

Because of the high degree of beam collimation, a laser serves as an almost ideal point source of intense light. A laser beam of sufficient power can the­oretically produce retinal intensities at magnitudes that are greater than conventional light sources, and even larger than those produced when di­rectly viewing the sun. Eye exposure to a direct beam can cause permanent eye damage including blindness. Protective eyewear should always be worn when potential exposure to direct laser beams exist.
Due to the lens-like focusing effect of the human eye, it is 100,000 times more susceptible to injury than the skin.
The laser protective eyewear must always be available for the wave­lengths of the laser used.
However, with regard to protection from laser radiation, eye protection equipment is the last step in the process. Engineering and administrative controls are the first step.
Do not wear jewelry when working with an open laser beam to prevent the beam from being reflected in uncertain directions.
If possible, use all protective housings, locking mechanisms and guards.
Always use laser protective eyewear when repairing, aligning or install­ing lasers or whenever a laser safeguard is not present.
7. Appendix A – Laser Safety

7.3.2 Thermal injury

Leica LPC
The most common cause of laser-induced tissue damage is thermal in na­ture, where the tissue proteins are denatured due to the temperature rise following absorption of laser energy. The thermal damage process (resulting in burns) is generally associated with lasers operating at exposure times greater than 10 microseconds and in the wavelength region from the near ultraviolet to the far infrared. Tissue damage may also be caused by thermally induced acoustic waves following exposures to sub-microsecond laser exposures.
41
7. Appendix A – Laser Safety

7.3.3 Skin injuries

Radiation in the UVA (315-400 nm) range can cause hyperpigmentation and erythema (sunburn). Exposure in the UVB (280-315 nm) range is most injuri­ous to skin. In addition to thermal injury caused by ultraviolet energy, there is also possibility of radiation carcinogenesis from UVB. The shorter wave­lengths are absorbed in the outer dead layers of the epidermis (stratum cor­neum) and the longer wavelengths have an initial pigment-darkening effect followed by erythema if there is exposure to excessive levels.
The dangers associated with exposure to the skin to radiation are less se­vere than the eye injuries; however, with the increasingly widespread use of powerful laser systems, particularly ultraviolet lasers, the skin of personnel can be exposed to hazardous levels of radiation if they are used in non-en­capsulated systems.
Skin burns caused by lasers can happen quite fast and with great intensity. Protective clothing should be worn when potential exposure to direct laser beams exist.
Radiation in the UVC (200-280 nm) range can cause erythema (sunburn), skin cancer and burns.
Radiation in the UVB (280-315 nm) range can cause accelerated skin aging, increased skin pigmentation and burns.
Radiation in the UVA (315-400 nm) range can cause pigment darkening and skin burns.
Visible radiation (400-700 nm) can cause photosensitive reactions and skin burns.
Infrared radiation (700-100,000 nm) can cause skin burns.
