An occupational safety specialist works with dozens of types of regulatory documents every day, and it is easy to get lost: how does NPAOP differ from DSTU, where to look for construction codes, and where for fire safety rules. Without clear navigation by class, finding the right act turns into flipping through reference books and running search-engine queries. The document search section of the portal solves this problem: more than 45,977 documents are structured by class, each class has its own explanatory landing page, and the navigation leads straight to the relevant list of acts.
What document classes are
A document class is its membership in a particular system of standardization. Each class has its own scope, its own developer, and its own coding logic:
- NPAOP — occupational safety regulations (rules, instructions, model provisions).
- DSTU — national standards of Ukraine (requirements for products, methods, terminology).
- DBN — state construction codes (design, construction, operation of facilities).
- GOST — interstate standards still valid in certain areas.
- NAPB — fire safety regulations.
- PUE — electrical installation rules.
Why this matters to a safety engineer
Understanding classes saves time at every stage of work. Once you know that electrical safety requirements live in PUE, fire-regime requirements in NAPB, and work-at-height rules in NPAOP, you immediately narrow the search. The explanatory landing page for each class describes in plain language what these documents are and what they are for, and links directly to the full list of acts in that class within the registry. This is especially valuable for new specialists and when preparing for inspections, when you need to quickly assemble evidence of the applicable requirements.
How to use navigation by class
In the search section you can filter the registry by document class, as well as by type and industry. If you do not remember the exact code, the system normalizes your input and finds the act even with imprecise spelling. Each document opens as a card with a short human-readable explanation, status and dates, full text, a download option, and a list of related documents — this helps you not miss adjacent norms.
An everyday scenario
Imagine you are tasked with updating the fire safety system at a warehouse. Instead of recalling specific codes, you open the NAPB class landing page, read the explanation, and move to the list of current fire safety acts. From there to NPAOP for warehouse-work safety rules, then to DBN for building requirements. In a few minutes you have a structured set of current documents instead of an hour of scattered searching.
Tips for efficient searching
- Start with the class, then narrow down by type and industry.
- Check the document status on the card — work only with current editions.
- Save the acts you need in your personal account so you do not search for them again.
- Review the related-documents block — norms that are easy to forget often hide there.
Master the classes once, and the registry will start working for you. Open the document search section, choose the class you need, and assemble an up-to-date regulatory base for your task in minutes.
