Study on Prevention of Accidents at Firefighting Operation through Analyzing a Potential Risk Using Reliability Analysis Technique - For the Extinguish Activities of Embers by Fireman

Many kinds of peculiar technology, skills or tacit knowings have been lost at the mass hiring and the mass retirement period in various industries in recent years. Fire fighting organization has also similar situation. Therefore, the risk that firemen get injured in firefighting would increase because of the reason above mentioned.
