Final answer:
The emo button is used to turn off the high-pressure gas cylinder during a chemical leak, while vermiculite is used to cover the fire surface. The emergency response helps to contain the situation and minimize the impact on nearby areas.
Step-by-step explanation:
The emo button, or emergency button, is pressed to immediately turn off the high-pressure gas cylinder when water-reactive and pyrophoric materials leak. This is done to prevent further release of potentially dangerous gases and to reduce the risk of fire or explosion.
Vermiculite is used in this situation as a priority material to fully cover the fire surface. Vermiculite is a mineral that has excellent insulation properties and can withstand high temperatures. When applied to a fire, it helps to smother the flames, preventing the spread of fire and reducing the risk of ignition.
The emergency response, including pressing the emo button and using vermiculite, aims to contain the situation and minimize the impact on nearby areas. By quickly shutting off the gas cylinder and covering the fire surface, the release of harmful gases is reduced and the risk of fire spreading is decreased, thereby protecting the surrounding environment and ensuring the safety of nearby individuals.
