Most building codes reference NFPA 80, Standard for Fire Doors and Fire Windows. This standard estabhshes the minimum rating for the most commonly encountered types of openings in walls stated in hours. With regard to fire doors, the following is a description of various types ... 

NFPA 80, Fire Doors and Fire Windows, hsts requirements for the installation of doors, windows, and shutters, and also specifies how the opening should be constructed and how the door or window should be mounted, equipped, and operated. 

Optical Properties. The high refractive index (2.42 at 589.3 nm) and dispersion (0.044) are the basis for the brilliance and fire of a properly cut gemstone. The optical transmission out to 10.6 p.m for Type Ila diamonds makes possible windows for CO2 lasers and for devices such as were in the... 

Prevention of arson Control access at all times Screen employees and casual labour Lock away flammable substances and keep combustibles away from doors, windows, fences Provide regular fire safety patrols, even where automatic systems are provided Secure particularly storage and unmanned areas... 

FIRE SIMULATOR predicts the effects of fire growth in a 1-room, 2-vent compartment with sprinkler and detector. It predicts temperature and smoke properties (Oj/CO/COj concentrations and optical densities), heat transfer through room walls and ceilings, sprinkler/heat and smoke detector activation time, heating history of sprinkler/heat detector links, smoke detector response, sprinkler activation, ceiling jet temperature and velocity history (at specified radius from the flre i, sprinkler suppression rate of fire, time to flashover, post-flashover burning rates and duration, doors and windows which open and close, forced ventilation, post-flashover ventilation-limited combustion, lower flammability limit, smoke emissivity, and generation rates of CO/CO, pro iri i post-flashover. 

After a period of 30 to 90 seconds following release, the flammable cloud was ignited. The time was then about 4 53 p.m. The explosion caused extensive damage and started numerous fires. The blast shattered control room windows and caused the collapse of its roof. It demolished the main office block, only 25 m from the explosion center. Twenty-eight people died, and thirty-six were injured. The plant was totally destroyed (Figures 2.4 and 2.5), and 1821 houses and 167 shops and factories in the vicinity of the plant were damaged. 

Heard loud explosion. Ran to control room and found that the windows had been blown in. Supervisor then sounded plant alarm. Then went to separation module and found it severely damaged and on fire.
