PART 2
iNFO FOR THE LSO & OTHERS RESPONSIBLE FOR LASER SAFETY
************************
HERE ARE SOME DEFINITIONS-
----------
AEL-- (ACCESSABLE EMISSION LIMIT)
the max accessable emission level or collateral radiation within a particular class
Accessible radiation= lasers which humans can have access to.
Angular radiation= the apparent visual angle, a, as calc. from a soure that is accessaible to humans
Apeture+ the PJ opening - any radiation from there to which humans arte accessible
Apeture stop+ means an opening serving to limit the beam size. and thus the area exposed
******************Certified laser product= product is 'maker' certified to be compliant -- not all sellers who claim to be doing this are being truthful.
CDHR= Center for Devices and Radiological Health (of the FDA)
Classes of lasers= from Class 1 to Class 4- high number higher hazard and power
Collateral radiation= electronic product radiation (except laser) emmitted by a laser as a result of operation. again CFR 1040.10
Continous Wave or CW- Not pulsed
Cosmetic procedure protocol= delegated written authorization to select specific laser or IPL settings , initiate, -for procedures and conduct necessary follow-up.
Demonstration laser= any made, designed , intended, or used for purposs of demo-entertainment, advertizing display or artistic.
Embedded laser= enclodsed laser with higher class number than the inherent capibility --where the system's lower capability of the laser system in which it is incorperated.
(engineered features that limit accessible emission).
Enclosed laser= contained within its own protective housing or
laser made- designed, intended or used
'Federal performance standards for light-emitting products'
= the regulations in 21CRF 1040... incorp. by refernece, published by the Off. of Fed. Reg. Nat. Archives & records W D.C.
Human access= capasity to intercept laser or collatreal radiation by any part of the human body.
Incident= an event or occruance that results in actual or suspected exposure to laser radiation (light) that has caused or likely to cause damage.
Intergrated radiance= rad. energy per unit area of a radiating surface per unit solid angle of emission, expressed in joules per sq. cm. per steradian.
Irradiance = tme ave. radiant power incident on an element of a surface divided by the area of that element, expressed in watts per sq. cm.
Laser energy source= any device intended for use in conjunction with a laser to supply energy for the operation of the laser.
Gen. energy sources like mains or batts are not considered by the Agency
Laser facility.= place where one or more lasers are used. class of laser matched class of facility. highest prevails.
Laser product= any manufatured product or assembledge of componenets that constitutes, incorps., or intended to become a laser.
Laser protective device= any used to reduce or prevent exposure like eyeware-garments-engineering controls and op. controls.
Laser radiation= all electromag. rad. emitted by laser within range spect. range specified in def of laser-- result of controlled stim. emission or that is detectable eith radiation so produced through the appropiate apeture stop and within the approp. solid angle ofacceptance.
More definations; (paraphrased and (at times) crude abbreviations plus typos sry)
LSO- ..with combined experience (w/control & evaluation of laser hazards) & training any may be designated by the 'registrant' and has authority /responsibility to 'administer a program for a particular class of facility'.
Laser systems- = a laser with appropriate energy source w or w/o
additional incorperated components/
Limited exposure duration or Tmax= the exposure is limited by design or use.
Maintenance= self service intended by the maker- to ensure preformance. (more later on this)
MPE- (max permissible exposure)-the level where no harm or hazard.
for both eyes and skin as per ANSI Z136.12000.
Medical laser product- med device lasers- any body part and for purpose of diagosis, surgery, therapy, or relitive position of the human body. Like the red laser that used to aim the X-ray by some.
Operation= preformance of the laser product over the full range of its function. (But not maintenance or service.)
Protective housing= portians of laser product that are designed to prevent human access any radiation.
Pulse duraton = time increment measured between half-peak- power points.(at leading & trailing edges)
Pulse interval= period between identical points in two pulses.
Radiance= "time-averaged radiant power per unit area of a radiating surface per unit solid angle of emmission, expressed in watts per sq centimeter per steradian",
Radiant energy= energy emitted, transfered, or recieved in the form of radiation expressed in joules.
Radiant power= time-averaged power emitted , transferred, or recieved in the form of radiation expressed in watts.
RULE of the nines= when you hear of someone having 40% burns ..this is how they figure this using regions of the human body-
like head & neck 9%--
Safety interlock= system that prevents exposure by removing parts.
a protective housing .Not easily accessed.
Sampling interval= presented by the symbol "t" (in seconds) the time interval of sampling by measurement the radiation in the process.
Secured enclosure -area where causal access is impeded by various means like door locks, latch, or screws to secure.
Service= procedures or adjustments described in service manual
Uncertified laser product= laser NOT certified or meeting requirements -by 21CFR 1040.10 ( pretty much 95% (or more) of the PJs on Greedbay-
