Transcript of MFD-MICROMAX PLUS

LUMIDOR MICROMAX PLUS/SERIES 1
MONTCLAIR FIRE DEPARTMENT
HISTORY
MICROMAX PLUS/Series One
OPERATION
OXYGEN
HONEYWELL INTERNATIONAL
-FOUNDED IN 1906 BY MARK C. HONEYWELL
-COMPANY MERGED WITH "Minneapolis-Honeywell Regulator Company", FIRST COMPANIES TO SUPPLY "DAMPER-FLAPPER THERMOSTATS"
-IN WWII, HONEYWELL JOINS THE DEFENSE DEPARTMENT WHICH STARTED THE AREOSPACE DEPT.
-FIRST TO DEVELOPE DOMESTIC CO MONITORING
Programbable gas detector
-reads up to 5 gases with combo-tox sensor
-Liquid Crystal Display
-high contrast 4 lines by 16 aplhanumeric display
-Display Backlighting
-automatic fiber-optic backlight
-battery can be used as NiCAD rehchargable pack or with 2 "AA" = 9 hours of operation (4 "AAA" for st. 2)*
-low battery alarm is double beep every 15 seconds
- *for micromax series one, 1 beep every 15 seconds until 1.9v is reached, then continuous alarm until unit shut down.
-Confidence Beep every 20 seconds, if programed, to insure instrument is working.
-battery gage, if programed, with up to 6 Bars
-Audible and Visual Alarms
-low flow (steady audible alarm with visual alarm)
-display indicates low flow
-RFI (radio frequency interference) minimizes false alarms
-Storage = 200 hours of data
- -4 to 122 degress F operation tempurature.
- 90 db at 1 ft
-16 ounces
DEFICIENCY
- LESS THEN 19.5%
- BECOME HYPOXIC
ALOC WITH MEMORY LOSS
DEATH MAY BE RESULT
Originally incorporated as EIC-Sieger in 1959 and later re-branded as J&S Sieger Ltd in 1961.
- Joshua Sieger invented the first low-power catalytic bead in 1958, designed for the detection of flammable gases onboard boats.
-Sieger sells company to Zellweger Analytics in 1979
-Zellweger is bought out and rebranded in 2005 by Honeywell; Honeywell Analytics
- Turn unit on by pressing ON/OFF button
-wait to hear confirmation beep.
-instrument will display firmware version #
-Instrument will go through "Testing" and "Zeroing" cycles, displays low-alarm and High-alarm levels
-indicates "ready" and goes into operation mode.
Different standard modes are available by pressing "MODE" button
-PEAK READING;(hightest toxic and combustible gas levels and the lowest o2 levels)
- STEL (short term exposure limit) values for toxic gases.
-TWA (time weighted average) for O2, LEL, Toxic gases.
-clear memory
REMOTE SAMPLING
-10' tube used for confined space or remote areas
-Insure instrument is in "P" pump mode
-connect hose to monitor
-place in space to be monitored and wait 2 minutes
-> may use up to 100' hose; add 1 sec. per ft added
-> hose should mainly be used for pre-sampling; may drain battery.
ALARMS
-If gas alarm is present evacuate if you do not have proper PPE.
-> low gas alarm = 3 beeps/red flashing light/flashing gas range on monitor.
-> high gas alarm = 3 beeps/flashing light/flashing gas range
->Low flow alarm= continuous audible alarm/ flashing LED with words "LOW FLOW"
-> Battery Shutdown = 5 audible beeps.
OXYGEN (O2) = 19.5% to 23.5%
COMBUSTIBLE (%LEL) Methane = 10% to 20%
CARBON MONOXIDE (CO) = 25PPM to 35PPM
HYDROGEN SULFATE (H2S) = 10PPM to 20PPM
HYPEROXIA
-OXYGEN TOXICITY
-BLOOD BECOMES ALKALOTIC
-CELL DAMAGE MAY OCCURE
-EFFECT CNS
-SIGNS AND SYMPTOMS
-TUNNEL VISION
-TINNITUS
-NAUSEA
-MUSCLE SPASMS
-ANXIETY
-DIXXINESS
-SEIZURES
CARBON MONOXIDE
-COLORLES, ODERLESS GASS PRODUCED BY BURNING MATERIAL CONTAING CARBON
-LEADING CAUSE OF ACCIDENTAL DEATH IN AMERICA
-SIGNS AND SYMPTOMS
-HEADACHE, NAUSEA, FATIUGE
-SOB, C.P., N/V.
-DEATH BY OXYGEN DEFICIENCY.
- 1,500 ppm is fatal
METHANE
NOT A TOXIC SUBSTANCE STANDING ALONE; THOUGH HIGHLY FLAMABLE.
-MAY CAUSE ASPHYXIATION IF IN A CONFINED SPACE OR AREA WITH POOR VENTILATION.
-CAN BE INTRODUCED TO BODY BY: INGESTION, INHALATION, AND TOUCH.
-MAIN COMPONET OF NATURAL GAS.
-SIGNS AND SYMPTOMS
-BLURRED VISION
-COUGH
-CNS DEPRESSENT (HYPOXIA)
-LOC
HYDROGEN SULFIDE
COLORLESS GAS WITH "ROTTEN EGG" LIKE SMELL.
- FOUND FROM HOT SPRINGS, UNDERWATER THERMAL VENTS.
-EFFECTS CNS
-ASPHYXIANT
-LESS THAN 50PPM - EYE IRRATION WITH MILD HEAD ACHE
HIGH LEVELS OF H2S
- > 100PPM, MAY NOT DETECT ROTTEN EGG SMELL.
-> S/S MAY NOT SHOW UP UNTIL 72 HOURS
THETHAL
- >1,000PPM WILL CAUSE DEATH WITHIN 30 MINUTES.
Calibration
**must be done in clean air environment.
**insure that calibration gas is within expiration date.
Station 152
- Use mode button to scroll to "user set up"
- depress "ON/OFF" button to enter
-instrument will count down to 0
-apply calibration gas.
-instrument will display "CALIBRATING"
-all sensors must be displaying post "CAL COMPLETE"
-instrument goes into purging countdown to 0
-memory is cleared.
Station 151
-use hex wrench to remove calibration screw
-turn on monitor.
-use wrench to tap switch inside port once.
-wait 30 seconds then apply gas; apply gas appropriate to instruments sensor complement.
-before removing gas, tap calibration screw again, then gas levels will appear on display.
-clear memory.
TWO TYPES OF CALIBRATION TIME FRAMES
- "bump test"
-exposes sensors to known concentration test gas every day
-calibration interval can be every 90 days.
- If "Bump Test" is not performed, check monitor every few days to insure nothing in you atmosphere is damaging sensors (high concentrations of combustible gas, terta-ethel-lead, sulfides or silicone lubricants).
-if this is done calibration interval is every 30 days.

- recalibrate if measurements are off by 15%.
