[…] at 7:33 a.m., we were dispatched to smoke at one of the stores in Nowogrodziec. After the first crews arrived at the scene, a thermal imaging camera and carbon monoxide detectors were used to rule out a fire.

The smoke was caused by leaking refrigerant from a refrigeration unit.

Fortunately, no one was injured.
