Before testing an extinguisher, what should you do according to manufacturer instructions?

Following manufacturer instructions is the most important initial step before testing a fire extinguisher. This is crucial because manufacturers provide specific guidelines and procedures that ensure the extinguisher is used and maintained correctly. These instructions are designed to promote safety, ensure effective operation, and maintain the integrity of the extinguisher.

By adhering to these manufacturer instructions, you can verify that you are executing the testing process in line with established protocols. This approach minimizes the risk of failure during an emergency, as it confirms that the extinguisher is in proper working condition. Other actions, such as checking the weight, ensuring it is fully charged, or reviewing the maintenance log, may all be part of regular maintenance and testing, but they should be carried out in the context of the guidelines laid out by the manufacturer to ensure compliance and safety.
