Question
There are approximately 10 explosions in the US every year due to agricultural grain (corn and soybean) dust. Why is corn dust so dangerous?A) Corn contains a lot of oil and is therefore very flammable.
B) Grain elevators use a lot of flammable material while processing the corn.
C) Corn dust has a lot of surface area and can be ignited by even a very small spark, which can be created simply by a person walking around.
D) Due to the presence of lots of agricultural material, grain elevators are especially rich in oxygen.
E) Workers are not careful about where they throw their cigarette butts, and sometimes set the corn on fire.
