But twice a month, the Fire and Rescue NSW crew from Morisset give it their best shot.

Under the leadership of Captain Steve McNulty, and the glare of floodlights, the crew of 18 gather at the Morisset station to hone their skills in a variety of mock emergency scenarios.

"There's a big difference between training and the real thing," Captain McNulty said.

Screaming casualties, hysterical relatives, and leaking fuels can all add to the stress of trying to extract a car accident casualty safely but quickly.

"It's much more intense in the real world," he said.

"There are so many variables."

Ambulance paramedics at car accident scenes can sometimes instruct the rescue crew to extract a casualty from a vehicle in a specific way.

If it means carrying the casualty out through the boot, Captain McNulty and his crew must find a way.

Multiple airbags in modern cars are another potential hazard during rescues.

Captain McNulty's crew have become well versed in identifying such threats and nullifying them.

The Morisset crew's territory extends from the M1 Motorway, at Toronto, to Hue Hue Road, at Wyee, and takes in the Watagan Mountains.

"But basically, we'll go anywhere we're sent."

In the past 12 months the crew has attended seven serious motor vehicle accidents. They have involved cars that have crashed down embankments and into trees, as well as on-road collisions.

But it's not all about car crashes.

"We've had to help ambos break into 12 homes this year to get to patients," Captain McNulty said.

Last week the crew helped to rescue a motorist whose four-wheel-drive had become stuck in bush in the grounds of Morisset Hospital.

"We even get called to help with animal rescues."

The crew was recently called to a Mandalong property to help extract a horse that had fallen into a sewer pond.

"That was a joyous job, I can tell you!" Captain McNulty smiled.
