Foam fire suppression systems

The foam fire-suppression system was neither fully installed nor operational on the three tanks containing flammables. 

Unless the laboratory is a very specialized one utilizing large quantities of flammable liquids, it is unlikely that a foam fire suppression system would be selected as a first choice. Foam-generating... 

Before the storage of the flammable liquid (crude sulfate turpentine, CST), there were no flammable materials in the terminals enclosure. Local fire protection agencies specified a fixed foam-piping, fire-suppressing system as a condition to store flammable liquids. The terminal s management agreed to the terms of the protection package. 

Outlier analysis also revealed one subject LAN9356 was miscoded. The subject, originally coded as moderately exposed (MOD), actually worked in Aircraft Fuel System Repair Shop and handled fuel-soaked fire suppression foam on the day of the test. After the subject s exposure code was changed and the Davis Monthan ABF LOW-exposed subjects from Monday and Tues-... 

The 1-hour separation required between the different occupancy classifications of Zone 2 and the Zone 2A canyon cannot be achieved due to unsealed and non-rated penetrations in the hot cell canyon walls. Although the potential of a fire occum ng in the Zone 2A canyon is very small, a manual foam suppression system has been provided for fires in the canyon to provide defense in depth. The pre-piped nozzles allow the application of a fixed amount of foam into the hot cell canyon from Zone 2, without exposing operators or emergency responders to high radiation levels, if a fire were to occur. 

The space or room containing the incinerator combustion chambers and their accompanying burners should have a fire detection and alarm system. Fire protection may be provided by automatic extinguishing means such as a water sprinkler system or a fire hose station. In particular applications, foam or powder may be more appropriate. Depending on the radiation level expected for some of the components, an automatic or remotely actuated suppression system may be required. 

An example of risk reduction is bunding between oil storage tanks to help to contain fire or spillage. Foam, sprinklo and otho fire suppression or detection systems do not prevoit fires or explosions, but may reduce tbe extent and amount of damage which occurs fiom such events.
