Where should HMIS, 6 year, hydrostatic tests, or other labels not be placed on a fire extinguisher?

Fire extinguishers are designed to ensure that critical information is easily visible and accessible to users in case of an emergency. The front of the fire extinguisher is typically the location where the primary labeling and instructions for use are displayed. Placing labels such as HMIS (Hazardous Materials Identification System), hydrostatic test dates, and other important information on the front could obstruct the visibility of these critical instructions, potentially leading to confusion during a fire incident.

The back, side, or bottom of the extinguisher are more appropriate locations for these additional labels, as they do not interfere with the main labeling and operational guidance that must be readily seen and understood. Therefore, keeping the front area clear allows users to quickly find the necessary information for effective use in an emergency situation while still maintaining compliance with safety standards.
