An important parameter in assessing the fire safety of a new product is the smokiness of the material with regard toits effect on visibility. Materials with tendency to produce high levels of smoke make it more difficult for people to egress from the affected area. Minimizing smoke is especially important in transportation systems such as planes, trains, and subways. It is also important to avoid smoke deposition in high impact areas like communication systems and computer facilities. Smoke deposition is also a major concern in high cost production facilities where a clean environment is crucial such as for semiconductor fabrication and for pharmaceutical preparation.
