PMU: short-term mobile protection
The Ukrainian Civil Protection Code defines a primary mobile shelter as a technical product, including block-modular formats, intended for short-term protection of people in an outdoor/location-based scenario. The legal definition specifies a period of up to 4 hours.
This makes PMU relevant to a particular protection scenario rather than a generic synonym for any modular shelter product.
PRU: a civil-protection protective structure
An anti-radiation shelter belongs to the civil-protection protective-structure system and is governed through a project and regulatory framework different from the PMU product category.
The current legal definition referenced by ShelterMetric describes PRU as a non-hermetic protective structure intended for people to remain for the defined period of at least 48 hours.
Different standards and project documents apply
- PMU: DSTU 9329:2025 is the dedicated national-standard reference;
- PRU design: DBN V.2.2-5:2023 and other applicable project requirements;
- modular protective structures can also require understanding the scope of DSTU 9195:2022;
- the final document set depends on the actual project category and solution.
Do not replace the required category only because another format is cheaper
A school, workplace, residential project or public location first needs its civil-protection requirement and project basis established. Only then can a project team determine whether a PMU, PRU or another format can satisfy part or all of the identified need.
