The Ronald McDonald House volunteer said the training meant he was capable of keeping his cool until the ambulance arrived.

"It definitely had its advantages there," Mr Fairgrieve said.

The long time volunteer took part in a refresher course at the accommodation for families undergoing treatment at Orange hospital on Thursday.

As one of about 25 volunteers who regularly spend the night at the facility, Mr Fairgrieve said the skill brush up is important to feeling prepared.

"You don't want any event to happen throughout the night but it always helps," Mr Fairgrieve said.

RMH executive officer Rebecca Walsh said the overnight volunteers undergo first aid and fire warden training, relationship and housekeeping trainings, as well as what to do if they have to bring someone into the house or hospital.

"In case something critical happens in the house they can react in a timely manner," she said.

PRM Training have been sponsors of the house since 2015, volunteering their services to train the men and women who work with families at the RMH.
