WHAT ARE
GASEOUS SYSTEMS?
• CO2, FM-200®, Novec™1230, Inergens
• CO2 and Clean Agents are non-conducting fire
extinguishants
• They vaporise easily and do not leave residue on
evaporation
• Clean agents consist of two types: halo-carbons or inert
gases
• They extinguish by cooling or diluting oxygen concentration
respectively
• Removing one of the aspects of the fire triangle: fuel, oxygen
& heat
• Gases are stored under pressure: CO2 50 bar, Novec™1230 25-30
bar,
Inergen 300 bar
• Thus the systems are dynamic ones

WHY ARE THEY USED?
W W W . C O L T R A C O . C O M
Resilience for special hazards & safety critical
infrastructure
• Fire systems are an essential, integral aspect of businesses
in
today’s globalised and interconnected world
• e.g. military, government, banks, data centres, power
generation,
shipping, oil & gas, museums, archives,
telecommunications
Benefits of gaseous extinguishing systems
• We understand fire brigades far more than we do our own
engineered fire systems
• What is wrong with the our current way of annual
inspection?
-
REGULATIONS
W W W . C O L T R A C O . C O M
ISO 14520-1:2015(E)
• Deals with the fire extinguishing systems contents, pressure
& the protected
space into which the system is installed
• 9.2.1.3 Allows for a maximum of 5% loss of contents & 10%
loss of pressure
• 9.2.4.1 to check for changes to the enclosure that would
affect the efficacy of
the fire extinguishing system
Thus, the need for improved implementation of the
regulations, moving to a call for constant monitoring
-
MAINTENANCE
• Annual/periodic inspections contain risk
• There is risk of accidental discharge or slow seepage:
resulting in too little agent to suppress a fire
• One of the highest chances of discharge occurs during
their maintenance: primarily from shutting down &
dismantling the system in order to weigh it
• Cylinders can be tested ultrasonically in 30 seconds
Raising awareness of fire risks &
understanding the value of regular,
effective inspections

ACCIDENTS & ANECDOTES
W W W . C O L T R A C O . C O M
• 2004 – Routine inspection of fixed CO2 system led to death of
four
Officers in Hong Kong
• 2011 – CO2 discharge on SD Nimble resulting in serious injury
to a
shore-based service engineer at HM’s Naval Base Faslane
• 2015 – CO2 leak at US coffee plant led to death of one
employee
FM Global: 1/3 business expire after a major fire
• Over filled & under-filled cylinders; 20% marine cylinders
suspected
• Cheap pressure gauges sticking in position
• Safety pins retained in cylinder valves after installation
• Paint covering severe corrosion

Step 1
• To find the liquid level in a cylinder of CO2, clean
agents,
transformer oil, refrigerants gases and more
Step 2
• Use Portasteele® Calculator tablet based app to convert
the
level height into the weight/mass of extinguishing agent
• Popular cylinder types saved to easy-to-find settings list
• Record and download results for added value servicing
Identify Liquid Level with Portalevel® MAX
PRACTICAL TERMS
Level to Weight/Mass: Portasteele® Calculator
• Ease of use, portability, rugged casing, accuracy and
reporting capabilities provides an unparalleled solution
• Future monitoring aspirations: Contents-Weight-Pressure
