time the monitor has been on








QRAEII 4 Gas MonitorQRAEII 4 Gas Monitor















QRAE cont.QRAE cont.

• Good reliable easy to use monitor• Monitor must be turned on in fresh air to

zero before exposure to test atmosphere• Monitor will tell you when it needs

calibration or a bump test• When this occurs, bring it to HCTC for

testing• If testing fails, loaners are available until

your monitor is serviced and ready for use
















ToxiRAE IIToxiRAE IIToxiRAE II

ToxiRAE II Single Gas MonitorsToxiRAE II Single Gas Monitors

• These monitors are designed as personalmonitors for workers in hazard areas

• We use them throughout Summit County forresponse purposes– Hydrogen Cyanide (HCN) 4-5 devices?

• Designed for overhaul/ Safe to remove packs• Should be in Battalion response vehicles

– Phosphine (PH₃) 2 devices?• Designed for Clandestine drug lab discovery• Should be on HM-2 and one is at HCTC currently













ToxiRAEToxiRAE

• Shows gas concentration• Displays STEL, TWA and

PEAKS• Will alarm at preset limit• Must be periodically calibrated

with span gas• Good meter to start, but only

shows one problem in amultiple problem world

• We need to know where theseALL are and when they werelast calibrated

TIFTIF

• The TIF is well known as a combustible gasdetector– TIF ids combustible gases by “ticking”– Faster the ticking the higher the PPM of the detected

substance is

• The instrument is sensitive to a number ofcombustible and toxic gases vapors andrefrigerants

• The TIF also identifies Carbon Monoxide– However, CO isn't picked by the device until it reaches nearly

20,000 ppm making it a highly toxic an now combustibleatmosphere.

TIF cont.TIF cont.

• The instrument contains bothvisual /audible confirmation ofhazards– About 10 PPM change produces

a change in tick rate– Spitball accuracy

• Specific purpose device– Has no ability to determine O₂

levels in a given area

• Best used pen-pointingsmall hazards– Small Gas Leaks
















ChemPro 100iChemPro 100iChemPro 100i

ChemPro 100i How does it work?ChemPro 100i How does it work?

• Ion Mobility Spectroscopy (IMS)

• Uses multiple Gas Libraries to try and detect TICs and TWAs

• These Libraries help to narrow down the specificity of your"question".

• Designed for toxic industrial chemicals (TIC) and toxic industrialmaterials (TIM)– Utilized for initial responders for WMD– Uses a radioactive source to ionized samples create a specific

signature– Signatures correlate with reference database in the device– Several databases make up chemical libraries

•

•

First ResponderFirst Responder

• This library offers a broadlist of TICs and should beused as the primary first-inlibrary to alert a responderthat a potential toxic threatfor these chemicals mayexist.




Clan LabClan Lab

• This library is used insuspected meth labs andwill alert when potentiallytoxic chemicals typicallypresent in clan labs maybe present at levels thatexceed TWA.




OverhaulOverhaul

• Use it during overhaulto see if theatmosphere is clearenough to doff SCBA.



IrritantIrritant

• This library couldbe helpful todetermine if anarea was able tobe reoccupiedafter lawenforcement hasdischarged pepperspray.




CWACWA

• This library is designedfor use in monitoringscenarios such asvenue security whereCWAs are not presentand would only beunder abnormalcircumstances.

• You could also use thislibrary if there was aknown chemical intransport that had beeninvolved in an accident.







Chemical HazardChemical Hazard

• Sometimes when in a Libraryyou may get a generic ChemicalHazard alarm. This is triggeredwhen one of the followingconditions is identified:

• An individual chemical isdetected which is not in thecurrent library selected

• A chemical mixture isencountered

• Environmental conditions areencountered that are not in thecurrent library.













Trend ModeTrend Mode

• While the unit is in Trend modeyou can use it as a sniffer topossibly locate the source of aleak or area of strongestconcentration.



How do I turn it on?How do I turn it on?

• Open top capcounterclockwise until you feela click.

• Press power button untilInitialization process begins.You will hear the fan turn onand continuously run.







How do I turn it off?How do I turn it off?

• IMPORTANT - anytime theunit is exposed to a productor gets any readings:

• The unit needs to run for atleast 30 minutes beforeshutting it down.

• Also be sure to close capbefore putting unit away.










MultiRAE PlusMultiRAE PlusMultiRAE Plus

MultiRAEMultiRAE

• Photoionization Detector (PID)• Detects 5 Chemicals using electrochemical sensors

and an ultraviolet lamp (VOC)• SFA MultiRAE is currently setup for

– CO (Tox1)– Hydrogen Sulfide H₂S (Tox2)

• The MultiRAE is capable of sensors for Sulfur Dioxide, Nitric Oxide, Nitrogen Dioxide,Chlorine, Hydrogen Cyanide, Ammonia, and Phosphine in its two toxic ports

• The MultiRAE alerts the user of low levels ofVOCs– cannot tell us what chemical is present; only that a

VOC is in the area

MultiRAEMultiRAE

• Turning it on takes awhile!– Turn it on, then go make a sandwich and wait

• It will then ask you if you want to fresh aircalibrate?– We always want clean air to calibrate with

• A Warning screen may indicate that the‘Warranty Expired’ on sensors– As long as the sensor calibrates it remains valid to use– HOWEVER, keep this in mind if you begin to see problems










MultiRAE Cont.MultiRAE Cont.

• MutliRAE must have its filter– Do not use without external filter

• MultiRAE has a rather loud airpump that must be on all thetime

• Air pump has the ability tobecome clogged with debris ifallowed to come in contactwith loose material

• MultiRAE will not tell you whatVOC you are dealing with













Calibrated LimitsCalibrated Limits

• As the monitor warms up it will indicate all of the limitsof the monitor– Carbon Monoxide

• Alarm Limits: Low 35ppm; High 200ppm, STEL 100ppm, TWA 35ppm

– Hydrogen Sulfide (H₂S)• Alarm Limits: Low 10ppm, High 20ppm, STEL 15ppm, TWA 10ppm

– Oxygen (O²)• Low 19.5%, High 23.5%

– Combustible Gas• Show percentage of the LEL

– VOC• Alarm Limits:, Low 50ppm, High 100ppm STEL 25ppm, TWA 10ppm

• View Warm Up screen as monitor sets up to confirmAlarm values have not been changed

Ludlum 2241-2Ludlum 2241-2

Radiation DetectionRadiation Detection

• Radiation instrument best described byhttps://www.youtube.com/watch?v=xmJLvEiidtQ

• Designed to be calibrated for two separatedetectors

• 3 position mass switch– Off– Ratemeter– Scaler










Ludlum 2241-2 RatemeterLudlum 2241-2 Ratemeter

• Measures amount of radiation exposurewithin a time period MREM/hr or REM/hr– Continuously updating information– Helping us know if time/distance/shielding measures are

enough

• Auto calculates– As rate increases, meter automatically moves from

mrem/hr to Rem/hr• Pre-set alarm function

– Alert on the LCD gives us a warning– Alarm means Danger and we must take action

Ludlum 2241-2 ScalerLudlum 2241-2 Scaler

• The scaler provides timed counts over aspecified period.

• With this information one can determinethe rate at which an area is contaminatedor object is omitting radiation.– Rarely used by emergency response

personnel, however, could be useful tomonitor zones over periods of time










Smith Detection UnitsSmith Detection Units

Gas and Hazmat IDsGas and Hazmat IDs

• Both of these units are specialized equipmentdesigned primarily for identification

• Both units utilize the same highly effective inspecific scenarios they are used for.

• If used correctly, this equipment makes thejog easier and more effective than ever; whileif used incorrectly they only waste time andeffort










Smith DetectionGasIDSmith DetectionGasIDSmith DetectionGasIDSmith DetectionGasID

Gas IDGas ID

• Highly specialized equipment– Designed more for identification and not as a monitoring

device

• GasID measures how gases and vaporsinteract with infrared light.– Each chemical has its own unique infrared fingerprint– When analyzed by the GasID results in an identification

• Can give up to a 95% accurate in its result due tothe unique reaction of chemicals to the infrared

• Product must be trapped in a high enough ppmsample for analysis– Often difficult to get enough product for analysis

Smith DetectionsHazmat IDSmith DetectionsHazmat IDSmith DetectionsHazmat IDSmith DetectionsHazmat ID

Hazmat IDHazmat ID

• Another highly specialized device designedfor identification of hazardous products

• Hazmat ID also identies liquids and solids• Hazmat ID has a greater usability than GasID

– Samples are added to the machine instead of captured– No need for high enough concentrations with HazmatID

• HazmatID often has sample contaminationissues– Often techs will find that the sample comes out as “rubbing

alcohol” from cleaning the lens– Other times the percentage return will be under what is

acceptable to be considered a match
