There were firefighting demonstrations, stations tours, and safety presentations.

Crookwell Captain Glenn Bonomini said it was an opportunity for people to get up close with firetrucks and special equipment, and ask firefighters about the critical work they do to keep communities safe.

He also said it provided the firefighters with a chance to teach people about staying fire safe.

The open day was a chance for people to thank their local firefighters for their commitment to protecting life and property, Minister for Emergency Services David Elliott said.

"The brave men and women of Fire and Rescue NSW (FRNSW) put their lives on the line to keep the community safe. Anyone who puts their own safety at risk for the community is a hero in my books," Mr Elliott said.

FRNSW Commissioner Paul Baxter said it was a chance to show people that firefighters do more than fight fires.

They can be called to road crashes, hazardous material incidents and natural disasters, urban search and rescue, and humanitarian relief.

It was a chance for families to talk to firefighters about home fire safety in the lead up to winter.

He said there has been a 10 per cent increase in the number of home fires during the winter months.

Most fires are starting in bedrooms and lounge rooms due to heaters and electric blankets.

Crookwell was one of the hundreds of fire stations across NSW that opened their doors on Saturday, May 18.
