•
Testing the plausibility of the safety plan and measures
Verification of the traceability and plausibility of the safety plan and the measures derived from this in
consideration of underlying constraints.
The test does not apply to systems for which this test has already been carried out in the course of a
permit or approval process.
•
Verifying the implementation of measures
Verification of the measures described in the safety plan with regard to their implementation includes a
holistic examination of the technical and organizational measures in accordance with the specifications
of the safety plan.
•
Checking the deadlines for the recurring tests
When doing so, assess whether the system can be operated safely until the next specified recurring
test.
•
Verifying the maintenance plan
When doing so, assess whether the maintenance plan is suitable for maintaining the safety of the system
until the next recurring test. The maintenance plan can also be used to test the technical protective
measures. It can also be part of an integrated management system
•
Definition of responsibilities
for the maintenance plan, definition of maintenance and inspection
content, e.g. when creating work plans, processing the maintenance and inspection content, e.g. in
the form of work plans, the assessment of deviations from the target state, and any necessary re-
pairs.
•
Determination of maintenance and inspection measures and deadlines for devices, protective sys-
tems, safety, control and regulating devices as well as their connections and interactions, technical
ventilation systems, gas warning devices and inerting devices and MSR devices
•
Comprehensible description of the required maintenance measures and deadlines e.g. in the form
of work plans, work equipment of comparable design can be summarized.
•
Implementation of the maintenance plan: Implementation of maintenance and inspection in accord-
ance with the defined maintenance plan, notification of completion of the implementation of mainte-
nance and inspection, documentation of identified repair needs and implementation of the repairs.
Necessary maintenance measures must be carried out immediately. Maintenance work must be car-
ried out by qualified specialist personnel who have sufficient experience in the maintenance of Ex
systems based on the maintenance plan. The maintenance plan and the implementation of mainte-
nance measures must be clearly documented.
6.2.2 Tests of technical ventilation systems, extinguishing systems, gas warning de-
vices, inerting devices, devices, protective systems or safety, control or regulating
devices, and other technical devices for explosion protection
Test content that has been checked and documented as part of conformity assessment procedures do not
need to be checked again. Verify the plausibility and completeness of documents.
The following points must generally be verified:
•
Technical ventilation systems, gas warning devices, inerting devices with regard to their suitability, their
functionality, their interconnections, their installation conditions, their proper condition, and their instal-
lation / assembly
•
Extinguishing equipment / fire suppression equipment
•
Devices, protective systems, or safety, control, or regulating devices within the meaning of Directive
2014/34/EU on explosion protection with regard to their proper condition, their suitability, their intercon-
nections, their installation conditions, and their installation / assembly
