What is the purpose of a fire extinguisher in the Model Shop?

The purpose of a fire extinguisher in the Model Shop is to provide a means to extinguish small fires and prevent larger incidents. Fire extinguishers are essential safety equipment designed to quickly put out fires before they escalate into more dangerous situations. By effectively using an extinguisher, individuals can contain a fire, minimize damage, and ensure the safety of themselves and others in the vicinity. This proactive approach is vital in a space where flammable materials may be present, as it can prevent injuries and property loss associated with larger fires.

The other options do not accurately reflect the primary function of a fire extinguisher. For instance, while signaling for help is crucial in emergencies, it is typically the role of alarms or communication devices rather than an extinguisher. Additionally, fire extinguishers are not meant for decoration; they serve a serious purpose in fire safety. Lastly, dumping flammable materials should not be associated with the use of a fire extinguisher and is not a safe practice in any environment. Thus, the function of extinguishing fires is clearly the most relevant and correct option.
