300 Training and Equipment Manual
SECTION 308.012 TANGO TX-1
PURPOSE
The purpose of this procedure is to provide instruction to Fresno Fire Department
(FFD or Department) members on the proper use and maintenance of the Tango TX-
1 Carbon Monoxide (CO) detector.
APPLICATION
All front-line Fresno Fire Department apparatus are assigned a Tango TX-1 to monitor
carbon monoxide.
OPERATIONAL POLICY
The Industrial Scientific Tango TX-1 shall not be stored on or inside the medical aid
bag, on the AED, or inside any tool compartment.
OPERATIONAL GUIDELINE
The Industrial Scientific Tango TX-1 should be carried by Company Officers or their
designee on all medical aid calls and/or incidents where carbon monoxide may be a
hazard.
The Industrial Scientific Tango TX-1 should be safely stored inside the apparatus cab
area away from alcohol-based cleaners.
FFD operates with the Tango TX-1 always on and should not be turned off by
members.
Gas detection monitors should not be exposed to active fire conditions. Extreme
temperatures and high level of contaminants may damage the instrument. Good
judgement and caution should be used to prevent saturating the sensors with
contamination.

PROCESS
OPERATING THE INSTRUMENT
• Ensure the monitor is on. Do not turn it off.
• Pressing the power button allows the user to scroll through the display
screens. The instrument automatically defaults back to the home screen
after a short period of no activity.
• To fresh air calibrate the monitor:
o Move to an outdoor location or clean environment.
o Zero the instrument by using the power button to scroll through
the display screens until you reach a zero with a slash icon.
o Press the Enter button to begin.
o The instrument will beep when it is done
ALARMS
• The Tango TX-1 is equipped with audible and visual alarms, each have
a high and low alert setting. These alarm thresholds are set in
accordance with FFD policy as well as State and Federal regulations.
• A low alarm consists of flashing red LED lights in addition to an audible
chirp.
• The high alarm consists of rapidly flashing blue and red LED lights as
well as a rapid chirping audible alarm.
Carbon Monoxide (CO): Low alarm activates at 25ppm
High alarm activates at 50ppm
NOTE: A display showing OR indicates over range (1000ppm) meaning
concentrations exceed the sensor’s ability to calculate. Leave
the environment immediately.
MAINTENANCE
Daily checks include checking that the instrument is on and operating. By design the
dual sensor technology does not require regular weekly calibration.
Contact the Hazardous Materials Response Team if repairs are needed or suspected.

DECONTAMINATION
The instrument may be wiped down with a damp towel or rag. Avoid getting moisture
into the sensor ports. Do not use chemicals to clean.
NOTE: Chemicals such as alcohol-based cleaners can saturate the
sensors and cause the instrument to alarm. If nearby equipment
requires decontamination, remove the monitor from the area
until the cleaning product vapors dissipate.
INFORMATION
The Industrial Scientific Tango TX-1 is a single gas detection monitor that uses dual
CO sensors that can measure the gas concentration in the atmosphere at the same
time but operate independently of each other. Each sensor will revert to operate as a
single sensor in the event its redundant sensor fails. This allows the instrument to
continue operating without the need to be turned off.
