Many Fort McMurray firefighters, unable to wear their usual air masks while battling a giant wildfire that attacked the northern Alberta city, are being screened for health problems because they spent several days breathing in hazardous smoke.
Some of the 180 crew have developed a persistent cough, says firefighter Nick Waddington, president of the Fort McMurray branch of the International Association of Fire Fighters.
