The article discusses how to prevent accidents in oil refineries by evaluating fire and explosion hazards. The researchers used a computer program called ALOHA to identify potential dangers from toxic, flammable, and explosive substances. By inputting information like chemical release details, the software calculates safe distances for flammable liquids and gases. The results show areas where hazards could pose a threat to people and property, helping to plan emergency responses for oil refineries and nearby communities.
