What should you always keep near an operating air compressor for safety?

Having a fire extinguisher readily available near an operating air compressor is essential for safety because air compressors can pose a risk of fire due to electrical components and potential oil leaks. If a fire were to occur, having a fire extinguisher within reach allows for prompt action to mitigate the danger, thereby enhancing the safety of the operators and the surrounding environment.

While pressure gauges are important for monitoring the performance and ensuring the safety of the compressor during operation, they do not directly address potential emergencies. Similarly, tools are necessary for maintenance and repairs, but they do not serve immediate safety purposes in the event of a fire. A first aid kit is crucial for treating injuries, but it does not prevent a fire or help mitigate its consequences. Thus, having a fire extinguisher nearby plays a vital role in emergency preparedness when operating an air compressor.
