Step-by-step explanation:
The location of a class A fire extinguisher is crucial for ensuring safety in a laboratory setting. According to safety regulations, a class A fire extinguisher should be easily accessible and located within a maximum distance from any point within the area it is intended to serve. It is essential for students and laboratory personnel to be familiar with the location of the fire extinguisher, as well as other safety equipment such as the eyewash station, to ensure they can respond quickly in case of an emergency. While the exact distance may vary based on local regulations and the size and layout of the laboratory, as a general rule, the extinguisher should be located no more than 75 feet away from the workplace area. It is also important that the path to the extinguisher remains unobstructed to allow for quick and easy access.
