LEAK-TEST LKT-7
1. TECHNICAL DESCRIPTION
The leak-test confirms that any leakage from the apparatus is within a safe and
acceptable limit. This Module details the procedure for leak-testing constant-flow
escape breathing apparatus.
2. TEST EQUIPMENT
This test requires the use of Leak-detection Fluid.
3. TEST PROCEDURE
1. Ensure that escape apparatus is fully-charged.
2. Use a soft brush to apply Leak-detection Fluid to connections and joints,
particularly around:
• Hose port;
• Reducer head;
• Contents gauge;
• Charging adaptor;
• Cylinder neck.
3. Pull firing pin on escape apparatus to begin constant flow of air.
4. Inspect connections and joints for evidence of bubbles, which will indicate a
leakage of air.
5. Rectify leakage in accordance with the Fault-finding Chart contained within the
Product Module of this Manual.
6. Once rectification has been completed, re-test apparatus as described above.
7. Testing is complete once no evidence of leakage is detected.
8. Upon completion, clean Leak-detection Fluid from apparatus.
9. Fully-charge cylinder and prepare escape apparatus for service as described in
