Add 2 Msa Altair Gas Meter Flashcards
MSA all tear digital gas meter is issued to who?
All engine and ladder companies.
The meter does not replace the existing SENSITTKX detector, but must be used in conjunction with it
What can the MSA all terra digital gas meter detect?
Is equipped with two sensors, one for combustible gas and the other for oxygen. The meter is calibrated to methane, the major component of natural gas. Although the meter is capable of detecting other combustible gas is, the displayed readings will not be accurate. For this reason, the meter should not be used to detect other than natural gas
Before turning the meter on the member must be an area free of contamination. Press the power button located in the center of the meter above the LCD screen. A self check test will take approximately___Seconds. During this test the meter will momentarily activate or three alarm types audible, visual and vibrating. One screen will display FAS prompt in the user to perform a fresh air set up. To perform the FAS what do you do?
40 seconds; press the power button again to perform the FAS. DFAS is used to zero the LEL sensor. Not performing FAS may affect the accuracy of the meter readings. The FAS can be bypassed by either pressing the reset right arrow button or waiting 10 seconds
While I am monitoring the meter will omit a vibrating pulse and flashing___ LED light every___Seconds to alert the user that the meter is operating
Green; 30 seconds
In fresh air, the normal sensor reading on the LCD should read?
0.0% LEL; 20.8% O2
The meter will alarm at the following LCD readings;
LEL- 10.0%
02- 23.5% oxygen in Riched
O2- 19.5% oxygen the deficient
After alarm activation consider using an additional meter to verify readings. The silence alarms press the reset button (right arrow)
If a meter malfunctions what show the officer on duty do?
Call Haz Mat operations and request a replacement. Hazmat operations shall I arrange for the pick up of the out of service meter and issuance of a replacement. Meter shall not be sent through the bag. One for one basis with the replacement meter become in the units permanent meter. Unit Sean that place identifying markings on the meter
When the atmosphere is above 100% LEL, the LCD symbol______Will be displayed under the COMB/EX icon. This is an extremely dangerous atmosphere that is indicative of a potentially explosive environment
XXX
When LEL readings exceed 100%, in addition to the LCD assemble XXX being displayed, the meter will enter into a lock alarm state. The lock alarm state cause the meter to shut down the LEL sensor and no longer read natural gas levels. To reset the sensor, do what?
Remove two fresh air and turn off then turn back on
The oxygen sensor was included on the meter since the LEL sensor requires oxygen to function properly. In an oxygen______Atmosphere the LEL centers will not be accurate
Deficient
The normal oxygen reading on the meter is 20.8%. The low oxygen level alarm is set at 19.5%. Upon activation of the oxygen sensor, member shall do what?
Don their SCBA face piece and notify the incident commander of abnormal axle oxygen readings on the meter. Notify the dispatcher of conditions. And have the utility company respond and request an ETA.
The high oxygen sensor will alarm at 23.5%. Oxygen inenriched atmospheres_____ Flashpoints of combustibles and______The chances of ignition of material not normally thought of as an ignition hazard.
Decreases flashpoints; increases the chance of ignition
A series of_____ along the screen under the O2 icon indicates the atmosphere is above_____% oxygen.
+++; 30%
This is an extremely dangerous condition since the actual readings are not known. Incident commanders shall take the necessary action to address the abnormal condition and initiate a Haz Mat response
