Which of the following actions can obstruct access to fire extinguishers?

Using fire extinguishers as doorstops is a clear example of obstructing access to them. When fire extinguishers are employed in this manner, they are rendered unusable and their location may not be immediately recognizable in an emergency situation. Fire extinguishers are critical tools for controlling small fires and need to be easily accessible at all times. If they are blocked or impeded by other objects, there could be a delay in responding to a fire, putting lives and property at risk.

Access to fire extinguishers should always be unhindered, ensuring that they are ready for use when needed. Proper placement involves strategic positioning, and using a fire extinguisher as a doorstop undermines this purpose entirely. In contrast, other options, such as placing them near exits or mounting them at eye level, are in line with accessibility standards and do not obstruct their intended use. Keeping fire extinguishers in open hallways also avoids obstruction.
