We need a national combustible gas leak detection code


National Sales Director, Chris May, joined up with the plumbing engineer magazine to discuss the importance of gas safety.

American Gas Safety are solving the problems with gas safety in boiler rooms through two methods: adding combustible gas detection and gas detection interlocks. In many cases, a gas detection interlock can save lives.

‘With more than a decade of designing authority control and gas detection systems, it still astonishes me that we don’t have a national combustible gas leak detection code. Refrigerant detection, yes. Carbon monoxide (CO) detection, yes. Nitrogen dioxide and CO in enclosed parking structures, yes. We even have hydrogen detection codes for battery storage or battery charging rooms.

These codes all make sense as they add protection and life safety to our designs. But we still don’t have a national requirement to protect mechanical rooms, the facilities they serve or the people working in and around them from the dangers of combustible gas leaks.

Boiler or mechanical rooms are areas where we see the majority of a building’s gas use. Heaters, boilers and burners are all combusting gas. The location of the boiler or mechanical room should be taken into consideration as well; they are typically found in the lower levels or basements of buildings. An explosion event there could damage not only the room itself but the structure of the building, placing all the occupants in danger.’

Detectors Coverage & Location

By | AGS

There are no official figures of the area coverage of gas detectors; however, 50-100m2 per detector is a reasonable general guide.
For ParkSafe Detectors in an open floor plan/garage e.g., 7500sq ft – The radius of coverage should be approx. 15.2 m (50 feet) per Detector or 2,310 sq.m (7,580sq. ft).

There are no specific standards governing gas detector location (unlike fire detection systems); there are, however, general guidance documents. The most relevant being IEC 60079-29-2: Part 29: Gas detectors – Selection, installation, use and maintenance of detectors for flammable gases and oxygen. Much of what it covers is also relevant to toxic gas detection.
Detectors should be mounted where a potential hazard of gas is most likely to be present.

The following points should be noted also when locating gas sensors. When locating detectors consider

• The possible damage caused by natural events e.g., rain or flooding.
• Ease of access to the gas detector for functional testing, observation and service.
• How gas may behave due to natural or forced air currents.

Locations for detectors will vary based on the intended application and target gas, they should be located near identified sources of a potential gas leaks/pockets where gas could quickly accumulate and areas of identified consequential risk to detect gas. The composition of the target gas and its density relative to air are used as the basis for the recommended height of sensors.

Generally, the installation height of a sensor for a heavy gas (such as propane) would be close to the lowest point in the area, and for a light gas (such as methane) would be close to the highest point in the area. These recommended heights may vary based on air flow and temperature conditions in addition to the proposed application and location – this is particularly apparent with oxygen depletion sensors, and the target gas that they are used for.

Target Gas Typical Position
Natural Gas/Methane (NG) High Level – (1ft) from ceiling
Liquid Petroleum Gas (LPG) Low Level – (1ft) from ground level
Carbon Monoxide (CO) Breathing Zone – (5ft 6”) from ground level
Carbon Dioxide (CO2) Breathing Zone – (5ft 6”) from ground level
Hydrogen (H2) High Level – (1ft) from ceiling
Oxygen (O2) *Breathing Zone – (3 – 5ft) from ground level

* If you are installing and monitoring Oxygen depletion – consider the density of gas for its application and position the detector accordingly i.e. ground level for high density gases
