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 definition in Article 32 describes PRU as a non-hermetic protective structure, including structures built from modular or block-modular components, intended to provide the defined protection conditions for at least 48 hours.

The Code also establishes a specific rule for PRU with capacity up to 50 people: their design and construction use modular or block-modular structures that meet national standards, while the completed structure must comply with the applicable building-code requirements.

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.
