San Francisco is poised to drop a requirement that skyscrapers have refill stations so firefighters can recharge their air tanks during a blaze. The city has required that new high-rises have the air refill systems for about ten years.
The rule was instituted after Los Angeles firefighters spent more than two hours lugging 600 air cylinders up 10 flights of stairs in a 1988 high-rise fire, and three Philadelphia firefighters died from smoke inhalation after running out of air in a 1991 blaze in a 38-story building.
But the air tank refilling systems, now in 20 San Francisco buildings, have never been used during a fire, and some firefighters don’t have confidence in them.
