We are down to do a Wartime NFS display at 12:00 and a Cold War AFS display at 15:30 on Saturday, but on Sunday the times are AFS at 10:00 and NFS immediately following at 10:40. We also hope to take part in the vehicle parade (11:10 Sat, 15:00 Sun) and put our TL in with other high-rise appliances (15:00 Sat, 13:45 Sun).
See www.newark999show.co.uk for visitor information.
John Sutcliffe will be Officer-In-Charge (OIC) of the NFS with David Moore OIC of the AFS.
NFS Display Overview
All available NFS vehicles will enter the arena and perform a couple of laps. All except the Fordson PE will leave and park up outside the arena. The PE will slip the escape by the tower, and drive off to set suction into the dam.
A fireman will go up the escape ladder, and find a casualty in the tower. The TL is summoned, and a Neil Robertson stretcher is hauled up.
By the time the TL is set in place and extended, the casualty is strapped into the stretcher. He is lowered to the ground using the TL as a crane. As soon as the casualty reaches the ground, a fireman will climb the ladder.
Meanwhile, the K2 will arrive, and set suction into the dam, and run out a couple of hand-held branches to tackle the fire.
As this happens, the ARP wardens and firemen will bring the stretcher to the foreground, where the casualty’s injuries are treated. If available, an ambulance will arrive to take the casualty to hospital.
The Fordson will then give water to the TL to continue fighting the fire. When the OIC deems the fire to be out, the order to ‘knock off and make up’ will be given. Once all equipment is made up, the firefighting vehicles will start to drive round the arena, with the OIC in the lead vehicle. At this point, the other vehicles parked at the back will join in, and once the complete convoy has completed a lap or two of the arena, the OIC will direct the convoy to return to base.
Practice for this session will be Friday afternoon with a ‘dress rehearsal’ 9:00 on Saturday.
AFS Display Overview
The convoy will form up outside the arena in the following order:
- Convoy Goddesses
- Petrol Carrier
- Hose Layer
- Relay 4 Goddess (If present)
- Relay 3 Goddess
- Relay 2 Goddess
- Delivery Goddess
- Base Goddess
The convoy will enter the arena and make two full circuits.
The Convoy vehicles will peel off under the pipe bridge, and park behind the dams. Note that crew members who do not have the relevant insurance must stay with the vehicles.
The hose layer will start at the dams, and will start laying hose. 8 lengths of 6-inch hose will be slaked and clamped ready for laying at speed (15-20 mph) as the layer makes an oval round the arena, heading back to the pipe bridge.
The base relay goddess and the delivery goddess will drop off the end of the convoy at the dams, and reverse back to set suction into the dam. Attention to be paid to position the goddesses to allow maximum view of the pumping by the public.
The 2 or 3 relay goddesses will follow the hose layer. The motorbike will indicate where a goddess should stop and break into the hose, and then catch up to indicate to the next goddess. Note that goddesses MUST drive slowly to not get too far ahead of the motorcycle. Once the hose is laid, the hose layer will go under the pipe bridge and park with the convoy vehicles.
The intermediate relay goddesses will connect into the relay hose using a nurse valve and a 45-degree bend.
The final relay goddess will connect to the nurse valve, and run out 4 delivery hoses which connect to the collecting head (either on the base of the pipe-bridge riser, or on a single length of 6-inch.
The delivery goddess will run out 4 delivery hoses, each to a ground monitor pointing towards the tower.
The OIC will despatch the motorcycle who will start at the final relay goddess and check that they are ready. This means all connections made, pump engaged and engine running at tickover. The motorbike will wait by any vehicle that is not ready before proceeding. On establishing that all vehicles are ready, the OIC, who will be near the base pump when the rider arrives, will then give the water on signal to the base pump operator, who will prime his pump, and run at low revs as the water fills the lines. As soon as water has passed the final pump, he will raise the pressure (and hence the flow rate). Maximum flow will be reached when all pumps are running at 3000 rpm.
As soon as water is circulating the relay, the delivery goddess can prime, and following ‘water on’ from the OIC, can deliver water to the fireground.
When ‘water off’ is given, it is given to the base pump. As each goddess stops receiving water, the inlet hose will collapse, and the engine knocked back to tickover. On the ‘Make Up’ signal, the hoses are disconnected and rolled, ready for collection by the RL. As the RL continues, the goddess will follow behind, till eventually all the goddesses are behind. As the convoy passes the non-operational vehicles, they tack on behind. Following a lap (or two) of the arena, the entire convoy leaves.
Each relay goddess should park with the joint in the hose directly in line with the outlet, and ideally with the wheels within 6” of the hose
It is not possible to prime the base pump in advance, as there is no valve on the 6-inch delivery. It will pump a substantial amount of water even on tickover.
As soon as a goddess is parked, the driver should engage the pump PTO, put the 2WD/4WD gear into neutral, and select 4th gear. The engine should be started.
The base pump controls the flow rate round the relay. All other pumps should adjust their revs until the inlet hose is still packed, but no water comes out of the nurse valve.
Assembling the victualic ring onto pipe or hose ends is much easier if they are lubricated with soapy water. Each goddess should carry a bucket with 2cm of water in the bottom, with a good squirt of washing-up liquid in it.
As soon as the pumping gets underway, a crew member with a suction spanner or crowbar will position himself adjacent to every joint, so that when the ‘knock off and make up’ signal is given, every joint will be split immediately and the ends moved apart, ensuring no kinks in the hose. Crew will start from the Goddesses rolling the hose towards the middle of the run, so that 2 hoses, and one clamp and rubber, are ready for the RL to collect.
Practice for this session will be Friday afternoon with a ‘dress rehearsal’ early evening on Friday.
