Description

FIRE SIMULATION CONTROL SYSTEM

The present invention relates to fire training systems. In particular, the present invention relates to a fire simulation rig comprising a control and safety system.

Fire simulation rigs are used to provide fire safety training which involves providing a controlled flame to a range of purpose-built products that replicate equipment/test devices used on a daily basis in commercial and domestic settings. The controlled flame is typically provided using a supply of gas (usually LPG contained in a gas cylinder), and ignition means such as a blow torch. The gas supply is typically remote from the replicate equipment and therefore remote from the flames. The size and duration of the flames can be controlled by an operator using a valve to increase or decrease the amount of gas being supplied to the replicate equipment. The more gas supplied, the bigger the flame. Trainees are required to select and utilise an appropriate extinguisher to extinguish the flames while the operator observes the technique of the trainee as they extinguish the flames. If the operator is satisfied with the trainee’s technique, they gradually reduce the gas supply until the flame has been fully removed.

In many countries, fire safety training is a legal requirement in the workplace. However, most workplaces do not have the means or personnel to provide in-house training and therefore employ the services of a qualified fire safety instructor to visit the workplace and provide on-site fire training using a fire simulation rig. Due to the requirement of being compact and transportable, there is a lack of control and regulation mechanisms provided on these rigs. In addition, the frequent transportation of these units often results in the rigs and associated equipment becoming neglected and faulty and the current rigs and equipment used do not provide the necessary means to carry out appropriate quality checks on these systems. The result is that any gas overpressure or gas leak in the system may go undetected. A gas leak left undetected can result in asphyxiation or, especially during fire training, may become ignited causing a fire or an explosion. Therefore, there is a need to provide a fire simulation rig having appropriate control and regulation mechanisms.

It is therefore an object of the present invention to provide a fire simulation rig operable to prevent gas leaks or gas over pressure.

It is a further object of the present invention to provide a fire simulation rig to enable increased control and regulation of gas delivery during fire safety training. It is a further object of the present invention to provide a fire simulation rig having means to enable appropriate quality checks.

Each valve is also capable of being in a configuration between the first configuration and the second configuration, wherein partial gas flow is permitted. Gas pressure at each distribution port 6, 8 is in direct correlation with gas flow such that as gas flow through a distribution port 6, 8 increases so does the pressure at that distribution port, and, as gas flow through a distribution port 6, 8 decreases so does the pressure at that distribution port 6, 8. The control arrangement 14 thereby enables an operator to control the pressure of the gas at each distribution port 6, 8. Each valve is configured to enable increased gas flow and pressure as it is moved from the first configuration towards the second configuration and each valve is configured to enable decreased gas flow and pressure as it is moved from the second configuration towards the first configuration. This enables gradual increase or decrease in gas pressure.

The control arrangement 14 has an actuation arrangement 16 associated with each valve to enable movement of each valve towards, away from and between the first configuration and the second configuration. This enables operation of each valve to open, partially open, or close, as required.

Further, this prevents gas overpressure or under pressure from the gas supply 20 or within the fire simulation control system 1 going undetected. This is in comparison to systems without pressure indicators whereby the operator is unaware of the pressure throughout the system and/or being delivered downstream. The pressure detection arrangement 18 provided in the drawings has a pressure gauge associated with each of the distribution ports, the pressure gauges having a dial to indicate the pressure level. An example of such pressure gauge includes RS PRO Bourdon Tube Pressure gauge having a liquid filling.

This enables an operator to determine if gas is being released unintentionally into the surrounding environment. An example of an appropriate leak detection arrangement is the Gaslow Adaptor Gauge - Propane. The fire simulation control system 1 has a level detector configured to connect to the gas supply and detect gas levels within the supply 20. The level detector has indication means to indicate gas levels within the gas supply 20 to the operator. The level detector arrangement enables an operator to determine gas levels in the gas supply 20 during or prior to beginning the fire safety training. Thereby, this enables appropriate planning for the gas safety training such that mechanisms can be put in place to allow safe refilling or changing of the gas supply 20, if required. The fire simulation control system 1 has a temperature sensor to detect whether temperatures internal to the gas supply 20 or surrounding the gas supply 20 are at an optimum or safe level.
