The causes of fires and explosions - 75 years later

75 years ago, this month, the worst airship disaster took place when the hydrogen filled Hindenburg air ship caught fire and exploded as it was completing its 35th trip across the Atlantic, killing 35 people. Till date there are many theories about the incident. The Smithsonian magazine has published an article that mentions "Realistic alternatives for the cause of the explosion include a buildup of static electricity, a bolt of lightning or a backfiring engine, but at this point it’s impossible to determine what exactly caused the spark".
Today, static electricity. lightning and backfiring engines are still causes of fires, though there has been a lot of development in each of these fields to avoid fires. The BP Texas refinery disaster was started when the vapour cloud ignited due to a back firing engine. There are numerous cases of fires due to static electricity and lightning. Though technology has improved, man continues to commit the same mistakes!
