Which of the following is NOT a part of the "quick check" for fire extinguishers?

In the context of fire safety checks, a "quick check" for fire extinguishers typically involves assessing critical factors to ensure the extinguisher is operational and ready for immediate use. One aspect of this quick check includes confirming that the extinguisher is fully charged, is in its designated location, and shows no visible damage, all of which directly relate to its effectiveness in an emergency situation.

The inclusion of an expiry date is not a standard part of the immediate visual assessment during a quick check. Instead, while maintaining awareness of expiration is important for overall safety and maintenance management, it is not something that can be quickly assessed at a glance. The focus of a quick check is on the extinguisher's current operational readiness rather than historical or future maintenance milestones such as expiry dates. This highlights the necessity of ensuring the extinguisher can be utilized right away without extensive checks that may require further investigation or missing documentation.
