As a result of September 11th 2001 US fire
experts are beginning to advocate the use of elevators in high-rise
buildings throughout a fire, both to carry firefighters to the site
of the blaze and as a secondary method (after stairwells) for evacuating
building occupants. The US National Institute of Standards and Technology
(NIST) has joined others to study ways to build ‘protected’
elevators.
As
reported at a recent conference in Malaysia,* NIST is working with
the elevator industry to develop and test redundant, more reliable
elevator-dedicated emergency power systems and waterproof elevator
components. NIST is investigating software and sensing systems that
can adapt to changing smoke and heat conditions, maintain safe and
reliable operation, and not shut down during fire emergencies. Such
changes could allow elevators to be operated with remote control
from the ground floor during fires, thus freeing urgently needed
firefighters from elevator operation duties.
NIST also will use its expertise
in virtual reality simulation to test scenarios for coordinating
firefighting activities, elevator egress and stairway evacuation.
By incorporating elevators into its graphic computer models, NIST
will help fire safety experts identify the most effective operational
procedures for specific fire conditions. NIST fire researchers hope
to collaborate on emergency elevator operations standards with colleagues
from around the world. Global standardisation should reduce confusion
during an emergency, enabling people to take evacuation actions
with confidence.
