What is the minimum height for service tags as per the requirements?

The correct minimum height for service tags as per the requirements is 5 inches. This specification is important for ensuring that the tags are visible and easily readable by anyone who needs to check the service status of the extinguisher. Proper visibility helps in maintaining safety compliance and facilitates regular inspections. Ensuring the tags are placed at this height helps prevent them from being overlooked, thereby supporting effective maintenance and inspection routines.

The options that suggest lesser heights do not meet these visibility criteria and could lead to situations where necessary inspections might be missed simply due to inaccessible or unnoticed service tags. Ultimately, the 5-inch minimum height serves as a standard that enhances safety and compliance in extinguisher servicing.
