What to do after an adverse tightness-test result
A sequence for control, scope review, diagnosis and documentation without treating the result as a volumetric reading or promising a repair.

A result that does not meet the method criteria should not be treated as a simple paperwork issue. It also does not establish, without diagnosis, which component failed or how much product was released.
1. Follow the response procedure
Keep the area safe, notify the facility lead and follow the internal plan. If there is evidence of a release, water, vapors, an alarm or immediate risk, the priority is risk control and coordination of applicable measures and notifications.
2. Review the report and scope
Confirm system identification, method, conditions, included components and result classification. For MESA 2-D, the independent listing describes a nonvolumetric method based on vacuum, acoustic signals and a water sensor. The 0.1-gallon-per-hour figure belongs to the method evaluation under defined conditions, not a volume automatically measured in each test.
3. Separate finding from cause
The result may justify further diagnosis, but it does not always locate the ingress or release point. The tank, connections, lines and other components should be investigated according to scope, without changing parts at random or claiming that one repair will solve the issue.
4. Document decisions and changes
Record the finding, immediate measures, inspections, components inspected, repaired or replaced, completion evidence and basis for the next step. If scope changes, state clearly what was evaluated before and what will be evaluated afterward.
5. Coordinate the procedure
Repeating a technical test does not replace DINASEPI inspection or guarantee certification. Confirm with the authority which report, validity and documentation apply to the facility.
Master Services can review the report and quote diagnosis, repair and another evaluation separately. Scope is defined from evidence, not an advance guarantee. To organize information before another visit, see our test preparation guide.
