What is QCVN 06:2022? Guide to Applying Fire Prevention and Fighting Standards

If you work in the construction industry or have a project requiring fire prevention and fighting (F&P) approval, then QCVN 06:2022 is a standard you cannot overlook. This is the national technical regulation on fire safety for buildings and structures, issued by the Ministry of Construction under Circular No. 06/2022/TT-BXD, which officially took effect on January 16, 2023.

At Bao Tin Steel, we understand that timely and proper updates on changes in the standards are key factors to help you avoid mistakes during design, construction, or fire safety permit applications. This article will explore the highlights of QCVN 06:2022, how to apply it effectively, and provide a full downloadable version for easy use throughout your project implementation process.

Scope of Application and Subjects of Regulation

QCVN 06:2022/BXD applies to all organisations and individuals involved in construction investment activities in Vietnam, including both new construction projects and renovation or repair works that involve changes related to fire safety.

If you are designing, constructing, or applying for permits for projects such as apartment buildings, high-rise houses, public buildings, warehouses, or factories, you are required to comply with this standard. Specifically, the types of projects that must be applied for include:

• Apartment buildings and collective housing up to 150 meters high, with a maximum of 3 basement levels.

• Detached houses with 7 floors or more, or buildings taller than 25 meters, or with a volume greater than 5,000 cubic meters.

• Public buildings, warehouses, manufacturing facilities, infrastructure works, transportation projects, etc.

However, not all projects are required to fully comply with the entire standard. Certain special projects, such as hydropower plants, chemical facilities, defence works, mining operations, or metro stations, may be exempt from some parts due to more specialised fire prevention and fighting requirements.

At Bao Tin Steel, we often assist customers in clearly determining whether their projects fall under the mandatory scope of QCVN 06:2022. From there, we provide precise advice on suitable fire prevention and fighting materials and equipment, helping to avoid waste while ensuring full compliance with legal regulations.

Main Contents of QCVN 06:2022/BXD

When you hold the QCVN 06:2022 standard in your hands, you might feel a bit overwhelmed because this document is quite extensive, consisting of 7 main sections and 9 technical appendices. But don’t worry, Bao Tin Steel  has summarised the most essential content you need to know:

1. General Requirements for Fire Safety

• This is the foundation of the entire standard, outlining design principles to ensure that the building not only meets fire prevention and fighting criteria but also facilitates evacuation and rescue during emergencies.

2.

Technical Classification of Fire

Building materials and components are classified based on their combustibility, smoke generation, toxicity of combustion products, etc. From this, the fire resistance rating and appropriate fire prevention solutions for each construction element are determined.

3. Ensuring Safety for People

This section is especially important if you are preparing fire prevention and fighting documentation. It regulates:

• Design of escape routes, corridors, and emergency staircases.

• Limitation of flammable materials on escape routes.

• Regulations for basement rooms, fire alarm systems, and smoke extraction systems.

4. Fire Spread Prevention

• QCVN 06:2022 requires the division of fire compartments, the use of fire-resistant walls and floors with specified fire resistance limits. Additionally, it mandates proper fire separation distances between adjacent buildings.

5. Fire Water Supply

• It specifies the indoor and outdoor water supply systems, including pressure, flow rate, storage tanks, and the service coverage of fire hydrants. This is a section you need to pay special attention to when selecting valves, steel fire pipes, and fire protection accessories.

6. Firefighting and Rescue

• Includes requirements for fire truck access roads, firefighting elevators, turning areas, roof access, etc., to ensure firefighting forces can reach the building as quickly as possible.

7. Implementation Organisation

• Defines the responsibilities of all parties involved — from investors, design consultants, construction units, to state management agencies.

All the above content is presented in great detail in QCVN 06:2022, but the important thing is that you understand it correctly and apply it appropriately according to the nature of each project.

Key New Features and Revisions in QCVN 06:2022 Compared to the Previous Version

If you have worked with QCVN 06:2021 before, you will surely notice that QCVN 06:2022 has many significant changes. These updates are not only technical but also reflect a quick adaptation to reality and recent incidents, most notably, the fire at An Phú karaoke bar.

Let’s review the key changes you need to be aware of with Bao Tin Steel:

1. Clear Changes in the Scope of Application

The new regulations provide more specific classifications for buildings, such as:

• Large-scale detached houses or those with commercial areas occupying 30% or more of the total floor area must also comply with the standard.

• The number of basement floors, building height, and volume are more clearly defined to avoid ambiguity during application.

2. Addition of the “Technical Justification” Mechanism

A very commendable point: instead of strictly following every fixed regulation, you (or the design unit) can propose alternative solutions, as long as you can prove that the fire prevention effectiveness is equivalent or superior. This approach creates flexibility, especially for projects with modern designs or those following international standards.

3. Updates to Many New Concepts and Definitions

QCVN 06:2022 clarifies a series of terms such as “fire safety height,” “atrium lobby,” “direct exit,” “smoke extraction door,” etc., helping readers understand accurately and reducing the risk of errors in design and approval.

4. Addition of More Practical Requirements

For example:

• Rolling doors and revolving doors are no longer considered emergency exits.

• Some public rooms (such as supermarkets and restaurants) are allowed to be located in basements if there is a clear evacuation plan.

• Curved staircases or zigzag stairs are permitted if they meet specific conditions, something that was strictly prohibited before.

5. Encouragement to Use Active Firefighting Systems

The new standard offers several technical incentives if a building is equipped with an automatic firefighting system (sprinklers), such as:

• Relaxed fire compartmentation requirements and increased allowable opening sizes.

• Reduced fire resistance ratings for certain structural components → This helps optimise construction costs while still ensuring safety if you invest properly in an active fire protection system.

It is clear that QCVN 06:2022 is not merely a “technical update,” but a shift in mindset—from rigid regulations to more open, flexible, and practical standards. However, because of this, deeply understanding, correctly applying, and fully proving compliance requires you to invest more in expertise and selecting certified equipment.

With experience accompanying hundreds of projects nationwide, Bao Tin Steel is ready to consult, supply, and support you to meet the stringent requirements of QCVN 06:2022 and related amendments.

Guidelines for Applying QCVN 06:2022 in Practice

It may seem complicated at first, but if you know the right approach, you can effectively apply QCVN 06:2022 to your project, from the design stage through construction and fire safety acceptance.

Here are some practical guidelines that Bao Tin Steel often shares with customers:

Starting from the Basic Design Phase

Right from the initial project planning stage, you should collaborate with a consulting unit experienced in QCVN 06:2022 to:

• Correctly classify the building according to the standard.

• Determine the fire safety height, number of basement floors, fire compartments, escape systems, etc.

• Integrate appropriate firefighting and fire alarm systems for each type of building (residential, industrial, public, etc.).

➡ This helps you avoid revising documents and saves time during the approval process.

Proper Approval and Acceptance Process

Fire prevention and fighting design documents must comply with the important parts of the standard:

• Section 3: Safety for People – Escape routes, smoke control.

• Sections 5–6: Water supply and firefighting plans.

• Appendices D, E, G, H: Many projects encounter issues here due to incorrect material selection, escape route dimensions, or improper fire separation distances.

➡ If you need a supplier of galvanized steel pipes, fire valves, outdoor hydrants, etc., that meet QCVN 06:2022 standards, Thép Bảo Tín always has stock available and provides detailed consultation.

For Renovation and Expansion Projects

If you are repairing or changing the function of an existing building, keep in mind:

• If the scale increases, escape routes change, or the function becomes more hazardous, QCVN 06:2022 must be reapplied.

• If only minor repairs are made without affecting fire safety, adjustments to the new standard may not be necessary. However, it is still advisable to consult experts to be certain.

Prepare Technical Justification (If Needed)

For designs that do not follow standard templates (such as using sliding doors, curved stairs, or new materials), you need to prepare a technical justification to prove that the solution still ensures equivalent fire safety.

➡ This is a new feature and also a great opportunity for innovative projects. But to do it well, you need a design unit and supplier who fully understand the standard. Bao Tin Steel is ready to connect and assist you.

In summary, QCVN 06:2022 is not difficult if you have the right approach and a reliable partner by your side. Bao Tin Steel is always ready to support you, from consulting on selecting compliant equipment to supplying goods on schedule, ensuring quality and clear origin traceability.
