A minvan ran into Engine 54 on Grand River near Biltmore while the fire truck was headed to a suspicious fire just a few blocks away. It had its lights and sirens when it was hit.

The crews involved in the crash were responding to a fire at a home on Rutherford Street. It's one of six abandoned properties, all near Grand River and Greenfield, that investigators believe had been purposely set on fire all between 6 and 8 a.m. Monday.

The measure was ordered by Six Nations fire chief Matthew Miller as part of heart month in February. The units were paid for by a grant from the Six Nations Community Trust.

Miller noted that, according to statistics provided by the National Fire Protection Association, cardiac arrest continues to be the leading cause of death for on duty firefighters in North America.

The association says 56 per cent of line of duty deaths in 2014 were the result of cardiac arrest.

Due to this "staggering" number, the Six Nations department has placed defibrillators on every fire truck in the fleet, Miller said.

"When the unthinkable happens, and a firefighter collapses on an emergency scene, we need to be prepared to provide the highest level of care possible."

He noted that the department also has introduced its firefighters to a livesaving technique known as firefighter down CPR.

Prior to the change, ambulance operators could drive at a speed of 25 per cent over the posted limit, while operating with lights and sirens.

The Calgary Police Service and the Edmonton Police Service don't have a specific number for what speeds police vehicles can drive at, but officers are expected to drive to an emergency event at a speed that is safe and reasonable.

Unlike Calgary, Edmonton officers mustn't exceed the limit by more than 50 km/h.

As for the Calgary Fire Department, crews can go as fast as they deem necessary, as long as its safe.

"Safety is the number one factor our drivers take into consideration," said Calgary Fire Department spokeswoman Carol Henke. "I don't think that they need to be looking down at the speedometer to know whether they're being safe or not -- they know intuitively and through experience."
