Equipment subject to technical inspection
Non-pressure and low-pressure vessels (with overpressure not exceeding 0.5 bar) used for storing poisonous or caustic hazardous materials are subject to technical inspection if the substances and chemical preparations were classified as hazardous (very toxic, toxic, harmful or caustic) under separate provisions.
Exceptions:
- vessels used for transporting poisonous or caustic materials subject to requirements set out in separate provisions,
- holding vessels not used for storage,
- packaging used for storing and transporting poisonous or caustic hazardous materials referred to in separate provisions,
- factory packaging of pharmaceuticals and medical equipment,
- articles and equipment containing caustic materials, especially dry and wet electric cells and vessels with caustic charges in foam extinguishers,
- vessels for radioactive materials.
Forms of inspection and deadlines for tests
| Type of working medium in the vessel | Vessel volume V < 60 dm3 | Vessel volume 60 dm3≤ V < 1 m3 | Vessel volume 1 m3 ≤ V < 5 m3 | Vessel volume V ≥ 5 m3 |
| very toxic | S | L | F | F |
| toxic | S | L | F | F |
| harmful | S | S | L | F |
| caustic | S | L | L | F |
| Explanations for the table: In the columns presenting volume, the letters have the following meaning: S – simplified technical inspection L – limited technical inspection F – full technical inspection Operating permits are not issued for equipment subject to simplified technical inspection. | ||||
Required technical documentation
Technical documentation issued by the manufacturer (to the extent specified in Section 42 of the Regulation of the Minister for the Economy of 16 April 2002).
Certification from the manufacturer of the vessel that the vessel was manufactured and tested in accordance with technical documentation and conditions set out in the licence to manufacture. This certification should be issued also by the installer if the vessel is installed on site.
A description of operation, together with data on accessories and power sources (application).
A diagram of connections to compatible equipment.
Data on corrosion protection, including a description of a cathodic protection system for underground vessels, if it is to be used.
A vessel location plan, showing where the vessel and related equipment are located, for vessels located in buildings.
A vessel location plan, taking into account the location of nearby buildings and equipment within a distance of 10 m, for vessels located outside buildings.
A report on leak tests for lining or protective coating, if such tests are required for the technical documentation.
A vessel operating manual provided by the manufacturer (for vessels ready for use) or prepared and/or supplemented by the operator.
The above documentation concerns also equipment put into operation once again, in which case it may be modified on the basis of qualification tests carried out for such equipment.
