Using a knife or sharp object is permissible when it is necessary to remove a glad hand gasket.

• A. True
• B. False
• C. Only if gloved
• D. Only with supervisor approval

Answer: (B)

When working on glad hand connections, you must follow approved tools and procedures to protect the air brake system and your safety. A knife or other sharp object is not a permitted method for removing a gasket because it can slice the gasket, damage the seating surfaces, introduce debris into the line, or cause a cut if you slip. These risks can lead to leaks, contamination, or injury, which safety rules aim to prevent. The correct approach is to use the designated gasket removal tool or an approved method described in the maintenance instructions, typically after isolating or depressurizing the line and installing a new gasket as required. Wearing gloves or obtaining supervisor approval does not change the fundamental rule: only approved tools and methods should be used.
