Twenty Hawke's Bay firefighters tested new safety gear as they "rescued" seven students in a training exercise at Havelock North High School.
New face masks equipped with a special breathing apparatus were worn for the drill, which involved volunteer firefighters from the Havelock North station.
Senior fire officer Anita Murrell said the masks, being rolled out throughout the country, scored top points from the fire crew.
"Inside the mask is an electronic voice enhancer, so you can hear the person next to you a lot better."
They also linked to the Fire Service radio system, eliminating the need for walkie-talkies, Mrs Murrell said.
