Class D Involves combustible metals such as magnesium, sodium, lithium and titanium. be a special one designed for particular material and situation know the specific extinguishing agent required before using the metal.


8.2       Fire and Smoke Doors

Fire doors are held open only with magnetic hold-open devices.  The fire doors are used to separate:

·         hazardous areas from each other, such as laboratories from patient-care areas;

·         buildings such as Children’s Hospital and John Sealy Hospital;

·         stairwells and laundry rooms from other areas.


Smoke doors:

·         are designed to divide buildings into smaller compartments to provide refuge from smoke during a fire;  for example John Sealy is divided into four smoke zones on each floor which close automatically when the fire alarm system sounds;

·         are designed to allow travel in either direction;

·         should be held open only with magnetic hold-open devices.


8.3       Fire Protection Outage Permit Systems

An outage permit system has been developed to ensure that fire protection systems, including sprinklers, Halon and alarm systems are not turned off or left off without the knowledge and approval of EHS.  Before any system can be deactivated or reported as being back in service, contact EHS at ext. 24190.
