Which of the following describes a container of chemicals that will put out a small fire?

A fire extinguisher is specifically designed to contain and expel a substance that can effectively suppress or extinguish small fires. They come in various types, each filled with different agents suited for different classes of fires, such as water, foam, dry powder, or carbon dioxide. Proper training on how to use a fire extinguisher is essential for safety and effectiveness during a fire emergency.

In contrast, ventilation equipment serves to improve air circulation and quality but does not influence fire suppression directly. A high voltage protector is used to prevent electrical hazards in systems with high voltage, and while it is crucial for safety, it does not address fire suppression. Lastly, a lockout system is implemented to ensure that machinery is shut down and remains inoperable during maintenance, again not directly related to extinguishing fires. Therefore, the fire extinguisher stands out as the clear choice for extinguishing small fires due to its specific purpose and functionality.
