Locking Pin

Locking Pin

The locking pin is a small metal rod typically located near the handle or top of the fire extinguisher. Here’s how it functions:

• Securing the Discharge Lever: The locking pin is designed to hold the discharge lever in place, preventing accidental activation.
• Tamper Seal: In most cases, the locking pin is attached to a tamper seal. This seal indicates that the extinguisher has not been tampered with and is ready for use. Breaking the tamper seal is a necessary step before extinguisher operation.

Using the Locking Pin:

When using a fire extinguisher in an emergency, follow these steps:

• Locate the Locking Pin: Identify the locking pin on the extinguisher. It’s usually a brightly colored metal rod with a tamper seal attached.
• Pull the Locking Pin: Grasp the pin firmly and pull it straight out with a swift, jerking motion. You might hear a popping sound as the tamper seal breaks, indicating the extinguisher is ready for discharge.
• Proceed with PASS Method: Once the pin is pulled, you can proceed with the PASS method (Pull, Aim, Squeeze, Sweep) to operate the extinguisher.

Importance of the Locking Pin:

The locking pin plays a vital role in preventing accidental discharges. Here’s why it’s important:

• Safety During Storage and Transport: A secure locking pin ensures the extinguisher doesn’t discharge unintentionally during storage, transport, or handling, potentially causing injuries or property damage.
• Accidental Activation Prevention: It prevents accidental activation due to bumps, vibrations, or someone unknowingly hitting the discharge lever.
• Maintaining Fire Extinguisher Integrity: A broken tamper seal indicates the extinguisher may not be fully functional and should be inspected by a qualified professional.
