Which of the following is a common cause for fire extinguisher inaccessibility?

Obstructions from furniture or equipment are a common cause of fire extinguisher inaccessibility because they can physically block access to the extinguisher. In an emergency situation, quick and easy access to a fire extinguisher is critical for effective fire response. When an extinguisher is blocked by items such as furniture, equipment, or other obstacles, individuals may waste precious time trying to locate and reach the extinguisher, which can lead to a more intense fire and significant damage or injury.

In contrast, regular inspection and maintenance ensure that extinguishers are operational and in good condition, and placement on well-lit mounts enhances visibility, making it easier to find them when needed. Clear signage helps indicate the location of extinguishers, reinforcing the ability to access them swiftly in an emergency. Thus, these actions contribute positively to accessibility rather than detract from it.
