Answer:
Hydrogen sulfide.
Explanation:
Hydrogen sulfide is a chemical compound formed due to the reaction of hydrogen and sulfur. It is a colorless, corrosive, poisonous and highly flammable gas having the foul smell of rotten eggs.
Under the United Nations/North America number datasheet, the identification number for hydrogen sulfide is 1053.
In this scenario, you respond to a fire at a pharmaceutical production plant. One of the outside storage tanks is on fire. The placard on the tank shows the ID number is 1053. Therefore, this material is hydrogen sulfide.
