Safety notes
A code of practice for operating gas turbines may be accessed from the Gas Turbine Builders
Association (GTBA) website on
GTBA.com
. The GTBA is the British Model Flying Association (BMFA)
advisory body for model gas turbines.
It is advised always to have a CO
2
or similar gas-type fire extinguisher with you when running the
engine – you never know when an emergency will strike and it is best to be prepared. If you need to
extinguish an onboard fire you should point the extinguisher into the front of the engine and not in
through the turbine end.
Always ensure, when running a gas turbine that you keep people 10m (30ft) clear of the area to the
side and rear of the engine as you would a propeller engine, as although a broken turbine is extremely
rare it is still technically possible and it is better to be safe.
When running the engine you should stand slightly in front and to one side of the engine, and not to
the side for the reason above.
Always wear ear defenders when running the engine as gas turbines have a high intensity noise level
(around 112db) close to the engine that can impair your hearing in time.
Never try to improve/speed up the starting of the engine by spraying ignition agents into the engine – a
dangerous flashback fire may result and you will in any case never improve the starting this way.
This engine is not a toy and can cause bodily harm to you or others if misused.
It is your responsibility as owner, to ensure safe, careful and considerate operation of your engine at all times, and
in accordance with the manufacturers instructions.
If you sell or give away this engine, please pass these instructions to the new owner.
This engine
must
only be run firmly attached to a secure and sturdy engine test stand or model installation. The
thrust is considerable for such a small size and mountings must be sufficient to withstand such forces. Use
appropriate screws and lock-nuts. The engine must not be run held in the hand or clamped in a vice.
This engine is an internal combustion gas turbine engine which generates large quantities
of heat – ensure the mountings and installation are appropriate for operation at these
elevated temperatures.
During operation and for a time afterwards there are parts of the engine which are hot
enough to cause serious burns – do not touch any part of the engine until it has cooled to
room temperature.
Always operate your engine in open air away from confined spaces as the engine exhaust
contains gases which can cause asphyxiation and nuisance from smells.
The exhaust gases are very hot (over 450’C) on leaving the engine and can cause burns to
skin or damage to objects close to it – keep exhausts clear of anything which is affected by
such heat.
This engine must not be used near flammable gases, liquid or materials.
Turbine fuel is poisonous to living beings. Keep it away from the mouth and eyes and from
contact with skin. Always store it in a marked container out of reach to children.
Turbine fuel has a relatively high flash-point but in certain circumstances can be highly
flammable. Keep it away from heat and sources of combustion.
The starting gas is highly flammable and must be used with extreme care. Maintain canister and fittings in good
leak-proof condition. Protect from sunlight and prevent exposure to temperatures exceeding 50’C. Keep out of
reach of children. Discard used canisters in a safe place and do not puncture or incinerate, even when empty.
Avoid deliberate inhalation.
