Update of the Fire Safety Design (FSD) Project for EV Charging Station Installation

Miroslav Hlúbik — Mon, 25 May 2026 14:41:29 +0000

The construction of electric vehicle charging stations has become a common part of modernizing residential buildings, administrative facilities, and industrial sites in recent years. However, as the number of electric vehicles increases, safety requirements are also rising – especially in the area of fire protection. Installing chargers today does not simply mean “adding electrical infrastructure,” but also verifying whether the building is prepared from the perspective of a Fire Safety Design (FSD) project.

In many cases, it is necessary to update the existing FSD project — not only due to legislation, but primarily because of real risks associated with the operation of battery technologies in enclosed or semi-enclosed spaces.

Why is updating the FSD project necessary?

Increased risk

Charging stations introduce higher thermal and fire risks.

Structural modifications

Interventions in construction or evacuation routes may be required.

New technology

Installation changes both the character of the space and its safety profile.

Technical systems

Often it is necessary to add fire alarm systems (FAS), ventilation, or detection elements.

Mandatory updates

Legislation requires FSD adjustments whenever technology changes.

Fire brigade requirements

Approval usually requires current FSD documentation.

Are you planning to install EV charging stations in a garage or underground parking facility?

Specifics of fire safety for charging stations

Risks of electric vehicles and plug-in hybrids

Thermal runaway and toxic emissions – battery vehicles may, in case of failure, cause thermal runaway, intense combustion, and release of toxic gases.

Technical requirements for spaces

Changes to layout and operational conditions – chargers may require changes in space usage, structural evaluation, and reorganization of parking areas.

Fire protection and safety systems

Detection, ventilation, FAS – operation of charging stations often requires upgrades to fire alarm systems, additional detection, ventilation, and emergency shutdown solutions.

Why does it matter?

Charging stations significantly change how a space behaves in terms of heat, flammability, and technology. These impacts must be assessed before installation, to ensure the environment is safe and that the approval process proceeds smoothly.

When is an FSD update required?

When changing electrical installation or load capacity
Installing chargers significantly changes electrical load, which must be incorporated into the FSD.
When fire risk classification changes
Battery technologies affect space categorization and safety requirements.
When adding technology to garages or parking facilities
In enclosed areas, ventilation, evacuation routes, and heat propagation must be assessed.
At the request of building authorities or fire departments
Authorities often require updated FSD documentation for approval of charging stations.
During related construction modifications
Any changes to structures, partitions, or fire signaling must be reflected in documentation.

Final recommendation for safe integration of charging stations

Charging stations significantly affect a building’s fire risk, technical requirements, and documentation obligations. Many buildings still do not have FSD documentation prepared for modern electromobility technologies, which can lead to complications during approval, unnecessary delays, or even dangerous situations in operation.

Updating the FSD project is a key step to ensure safe operation of charging stations, compliance with legislation, and a smooth approval process. If you want to be sure your building is ready for electromobility without risks or additional costs, we will be happy to help.

Water Mist: A Modern Standard of Fire Protection in Demanding Projects

Miroslav Hlúbik — Thu, 21 May 2026 11:00:08 +0000

In the field of fire protection, we increasingly encounter a technology that is gradually changing traditional approaches – water mist systems. Although they are already part of many projects, their operation and real benefits are not always fully understood.

So why is water mist becoming an increasingly common choice in demanding applications?

How Water Mist Works

Water mist uses finely atomized water droplets that have a significantly larger active surface area compared to droplets in traditional sprinkler systems. This principle delivers three key effects:

intensive fire cooling,
local reduction of oxygen concentration,
limitation of heat radiation and fire spread.

The result is effective fire suppression with significantly lower water consumption and reduced impact on protected technologies and building structures.

Where Water Mist Makes the Most Sense

Today, water mist is mainly used in environments where traditional systems cannot effectively combine safety with damage minimization:

Data Centers and Admin. Spaces

Water mist systems provide effective fire protection without damaging sensitive equipment. They minimize water consumption while reducing the risk of critical infrastructure failure.

Tunnels and Transport Infrastructure

Water mist quickly cools the environment and limits smoke spread, increasing safety for people and emergency responders. It is an ideal solution for demanding transport conditions.

Historical and Heritage Buildings

Thanks to fine water distribution, water mist can extinguish fires without damaging valuable historical elements. It represents a gentle and reliable solution for protecting cultural heritage.

Industrial and Energy Facilities

Water mist effectively suppresses fires in high-risk technologies while reducing water consumption and secondary damage. At the same time, it supports employee safety and operational continuity.

Practical Advantages

With proper design and application, water mist offers several practical benefits:

lower water and storage requirements,
reduced secondary damage caused by firefighting,
more compact technical solutions,
high efficiency even in complex or sensitive environments.

This makes it a suitable choice for projects with high reliability and asset protection demands.

Understanding Through Real Testing

For designers and investors, it is not enough to know only technical parameters. It is crucial to understand system behavior in real conditions.

That is why certified fire tests play a key role, demonstrating real performance across various scenarios – from enclosed spaces to complex infrastructure applications.

VID Firekill Seminar 2026

In this context, it is worth mentioning a specific professional initiative by our partner. VID Firekill is organizing an international seminar on September 22–24, 2026 in Svendborg, Denmark.

The seminar focuses on:

practical demonstrations of water mist technology,
real fire tests in a certified testing facility,
expert discussions with international specialists.

For professionals, this is a unique opportunity to see the technology in action and gain practical insights for design and implementation.

3MON: Practical Water Mist Solutions

At 3MON, we focus on designing and implementing fire protection systems using modern technologies, including water mist.

As a VID Firekill partner, we deliver solutions based on real-world experience and verified testing. Our goal is to design systems that:

meet specific project requirements,
comply with current standards and regulations,
provide maximum protection at optimal cost.

FIRETEST 2026 – After the Electric Vehicle Fire, We Successfully Simulated Fires Involving Photovoltaic Systems and Battery Energy Storage

Miroslav Hlúbik — Tue, 05 May 2026 10:01:59 +0000

The safety of modern technologies has become one of the most widely discussed topics in the field of fire protection today. While in 2024 we focused on electric vehicle fires in garages, FIRETEST 2026 naturally expanded to other critical areas – photovoltaic systems and battery energy storage, which are increasingly becoming part of buildings, companies and public infrastructure.

Electromobility and decentralized energy systems are growing rapidly in Slovakia. By the end of 2025, more than 24,000 battery electric vehicles were operating on Slovak roads, with forecasts indicating growth to approximately 150,000 vehicles by 2030. At the same time, charging infrastructure continues to expand – today, more than 3,000 public charging points are already available, with thousands more expected in the coming years.

This development brings new challenges not only for designers and building operators, but also for fire and rescue services. Photovoltaic systems, battery storage and charging technologies exhibit specific behavior in the event of damage or fire, which cannot be reliably assessed through theory alone.

For this reason, FIRETEST was once again conducted under real conditions at the Lešť Training Center, where fires involving these technologies were simulated in a controlled environment. In cooperation with the Fire and Rescue Service of the Slovak Republic (HaZZ) and the Slovak Electric Vehicle Association (SEVA), we were able to take part directly in testing scenarios that reflect the current development of energy systems and electromobility in practice – and provide answers to the questions the market is asking today.

FIRETEST 2026 focused on one of the key topics of the safe transformation of the energy sector – fire protection in the field of renewable energy, specifically photovoltaic systems, battery energy storage systems (BESS), and related electrical installations.

The principles of safe installation of photovoltaic systems play a crucial role in the prevention of failures and fires. As the use of these technologies in buildings and infrastructure continues to grow, so does the need for a systematic approach to fire safety already at the design and installation stage. Particular emphasis must be placed on high‑quality project documentation – covering both electrical installations and fire safety design – correct placement of technologies, compliance with separation distances, creation of access routes for fire brigades, safe cable routing, the possibility of central system shutdown, and clear identification of buildings equipped with PV systems.

The objective of the test was to simulate conditions as realistically as possible that firefighters and system operators may encounter in real‑world scenarios.

he first part of the practical demonstrations focused on an outdoor wallbox installation. However, the wallbox itself was not tested intentionally – instead, the focus was placed on the electrical distribution board, which is most often the source of failures and subsequent fires in real‑world scenarios. An automatic fire suppression device MAUS STIX Pro was installed inside the distribution board. Following a simulated short circuit, the device was activated by thermal detection at a temperature of approximately 170 °C and filled the internal space with a potassium‑based extinguishing agent. This demonstration also presented an environmentally friendly fire suppression principle without secondary damage.

The test then moved to a pitched roof equipped with VITVOLT 300 photovoltaic panels. The fire was initiated using an open flame in order to controllably simulate a fire originating in the photovoltaic structure. In addition to observing the behavior of the structure during the fire, one of the key objectives was to verify the functionality and reliability of early thermal detection using the LISTEC detection cable, which operates as an electrical fire alarm system (EPS). The test also highlighted the importance of material reaction to fire and the development of new photovoltaic panel types classified as A1 (glass–glass), which do not contribute to fire spread. The use of older panel models made it possible to observe the behavior of existing systems under real operating conditions.

Another part of the test was carried out on a flat roof, where a photovoltaic system fire was simulated using the same principle of early detection, but with a different fire suppression solution.

The final scenario focused on a battery energy storage system (BESS) with a capacity of 25 kWh. The fire was initiated using an open flame to assess system behavior, detection speed, and the possibilities of early intervention before full fire development.

RTVS Report:

In photovoltaic systems, linear heat detection using the LISTEC cable was deployed. The system is classified as an electrical fire alarm system (EPS) in accordance with EN 54, and is accepted by insurance companies as an enhancement of the level of fire protection. The detection cable was installed directly within the panel area, enabling early identification of thermal anomalies.

Firefighting units subsequently demonstrated the extinguishing of photovoltaic panels using a fire extinguisher with a polymer‑based agent. After application, the agent forms an impermeable layer on the panel surface, which within seconds significantly reduces electrical power generation and thus lowers the risk of electrical hazards to responding units.

On the flat roof, in addition to LISTEC detection, a water mist system PV Protect Stop by MINIMAX was deployed. This system is specifically designed for extinguishing fires on photovoltaic roofs and for minimizing consequential damage.

During the battery energy storage system (BESS) fire, a key role was played by ASD Securiton Fire aspirating smoke detection. Suction piping was installed inside the battery rack enclosure, providing continuous monitoring of smoke concentration using optical detectors. Within seconds of fire initiation, the system identified the risk and enabled an early response at a very early stage of fire development.

FIRETEST 2026 confirmed the importance of practical testing of modern technologies under real‑world conditions. During the individual scenarios, valuable technical data and observations were collected, providing a better understanding of the behavior of photovoltaic systems and battery energy storage during fire events, as well as the possibilities for early detection and safe intervention.

The insights gained will serve as an expert basis for further discussions and potential updates to the legislative and regulatory framework in the field of fire safety. The objective is to establish rules that reflect real risks, ongoing technological development, and the needs of responding firefighting units.

FIRETEST 2026 once again demonstrated that the safe development of electromobility and renewable energy sources depends on the close integration of practical experience, modern technologies, and cooperation with fire brigades – a principle long emphasized by fire safety specialist and CEO of 3MON, Simona Kalinovská:

„By using state-of-the-art detection, handling and extinguishing systems, we can much better protect not only property, but most importantly human health and lives, including safe conditions for the firefighters themselves.”

Floor Marking in Real‑World Conditions (OHS)

Miroslav Hlúbik — Fri, 17 Apr 2026 06:10:06 +0000

Floor marking is a simple but important tool for managing the movement of people and equipment in work environments. Properly designed marking has a direct impact on workplace safety, clarity, and operational flow. It is most commonly used in warehouses, production halls, logistics centers, parking facilities, and technical operations.

Why address floor marking at all?

Without clear marking, operations become unclear and hazardous:

pedestrian traffic mixes with material‑handling equipment,
safe and hazardous zones are not clearly separated,
visual orientation within the space is missing.

The result is an increased risk of workplace injuries, process disruptions, and problems during OHS inspections. Floor marking resolves these situations immediately and clearly through visual communication.

Floor Marking and OHS

From an occupational health and safety perspective, floor marking primarily serves to:

separate pedestrian routes from equipment traffic,
mark hazardous and high‑risk zones,
indicate escape routes and safe areas,
highlight obstacles, columns, and collision points.

During inspections, emphasis is placed especially on clarity, consistency, and up‑to‑date marking.
Damaged, inconsistent, or outdated markings are often considered just as serious a problem as their complete absence.

Basic Types of Floor Marking

In practice, floor marking consists of several elements that, when properly combined, create a clear and easy‑to‑read system at first glance:

Lines and Routes

– movement of people, forklifts, and material handling, supply and logistics routes

Zoning of Space

– storage areas, workstations, safety distances

Symbols and Pictograms

– warnings, prohibitions, and orientation signs, aplied directly on the floor

„Floor marking is not a design element, but a functional safety tool. In practice, it determines whether the movement of people and equipment is clear, controlled, and safe.“

Colors of Floor Marking and Their Meaning

Colors must have a consistent meaning across the entire facility, otherwise they lose their function:

Yellow – routes, traffic lanes, work areas
White – organization and storage layout
Red – prohibition, danger, fire‑safety equipment
Green – safe zones and escape routes

A common mistake is using the same colors for different purposes or combining them without a clear system.

Implementation of Floor Marking

The method of implementing floor marking must take into account floor load, operational characteristics, and the need to maintain smooth pedestrian traffic. In industrial and logistics environments, it is not feasible to shut down operations and wait several days for conventional paint to cure.

For this reason, we use modern UV technology with immediate curing, which allows application without operational downtime and ensures instant usability of the space.

UV floor marking is characterized by high chemical and mechanical resistance, long service life, and a clean application process without odors or solvents. It is suitable even for demanding conditions at temperatures from –25 °C to +35 °C. Each marking is designed according to actual movement of people and equipment and in line with OHS requirements to ensure clarity, consistency, and functionality even under intensive use.

Floor Marking by 3MON

At 3MON, we provide both design and implementation of floor marking, with full respect for OHS requirements and real workplace conditions. Each solution is tailored to the specific space and its intended use.

Celebrating 15 Years of 3MON in the Spirit of Technology

Miroslav Hlúbik — Thu, 16 Apr 2026 10:03:30 +0000

On the occasion of the 15th anniversary of 3MON, we met with colleagues from our partner company JKBOZ to mark this milestone in a way that is close to us – through technology, live demonstrations, and personal interaction.

The event was opened by founder and CEO Simona Kalinovská, who delivered a short address and shared the history of the company, its development, and key milestones over the past fifteen years. She outlined why 3MON has been built from the very beginning on technology, a system-based approach, and continuous education.

A day Full of Technology

The program of the day was prepared not only for our colleagues but also for our partners from JKBOZ, for whom we wanted to practically demonstrate the solutions we work with. The program included a presentation of the MAUS system, along with a live demonstration of its functionality during a simulated fire in an electrical distribution cabinet. We also introduced the FIRE ISOLATOR fire blanket, NEURUPPIN fire extinguishers designed for lithium batteries, and discussed their possible applications.

Participants also had the opportunity to try out VR glasses, through which they could test their abilities in firefighting and first aid scenarios within a virtual environment. The program was further enriched by the interactive game Rescue Mission, combined with a competition for a wellness entry.

As an additional technological highlight, we showcased the Colossus firefighting robot, which arrived from France and offered a broader perspective on modern tools used in the field of fire protection.

„Some days are about technology. The important ones are about the people around it.“

Space for Conversation and Good Food

An informal part was also an integral part of the day, during which we made time for conversation and the sharing of experiences. It was precisely these moments that created space for personal meetings, feedback, and discussions beyond the usual work context. The celebratory cake cutting symbolically marked the end of the official program. Lunch was prepared by Andrej Duban, whose steak and burger specialties helped create a relaxed and welcoming atmosphere throughout the day.

The anniversary day was above all a meeting of people who stand behind 3MON projects and collaborate in bringing them to life. It offered a moment to slow down, reflect on our shared journey, and reaffirm that personal connections still have a strong place in a highly technical world. We would like to thank everyone who joined us.

Come to FireTest 2026 – an event that pushes the boundaries of fire protection

Miroslav Hlúbik — Tue, 07 Apr 2026 07:43:58 +0000

The safety of modern technologies requires more than discussion — it requires proof. This is why FireTest 2026 is a unique event that pushes the boundaries of what we consider safe. In the real conditions of the Výcvikové centrum Lešť, authentic fire tests will once again take place on April 29, 2026, putting to the test the technologies we encounter today in cities, companies, and households.

Three real fire scenarios that show more than theory can

Fire protection for wallboxes

The test will demonstrate how quickly the ASD Fire System and MAUS Stixx Pro candetect and stop a fire in an AC charging station.

Fire protection for photovoltaic systems

A simulation of a panel fire will verify the effectiveness of LISTEC and MINIMAX technologies in detecting and extinguishing solar system fires.

Fire protection for battery storage systems

The test will identify the most suitable detection and extinguishing solutions for the safe operation of battery storage systems.

„FireTest is not a conference, but an event where technologies are tested under real‑world conditions. It is the only place in Slovakia where professionals can see the actual course of fires, system reactions, and test results broadcast live.“

Why is FireTest so important?

After FireTest 2024, where an electric vehicle was intentionally ignited inside an enclosed space, new guidelines were created that enable the safe parking and charging of electric vehicles even in underground garages. The event showed that practical data from real tests can shape technical and legislative solutions — and change practice on a large scale.

FireTest 2026 has clear objectives:

verify new possibilities for the placement of early fire‑detection systems,
prepare technical background materials for the safe operation of photovoltaics,
identify key measures for battery storage safety.

An event for professionals who seek answers, not assumptions

FireTest 2026 is intended for everyone who makes decisions about safety — from facility managers and designers to industry technology leaders, firefighters, and rescue services. The benefit is clear: data from real‑world conditions that cannot be gathered in an office or laboratory.

At FireTest 2026, you will see how the latest detection, monitoring, and extinguishing technologies behave in situations that can arise at any time in real life. And that is the real value of this event — the opportunity to test the systems that protect our homes, health, and critical infrastructure. See it live.

Night Work: Health Risks and Effective Prevention

Miroslav Hlúbik — Wed, 04 Mar 2026 12:53:41 +0000

Night work represents an increased strain on the human body and is associated with higher health risks. That is why legislation precisely defines and regulates the obligations that employers must follow to protect their employees. Correctly identifying who qualifies as a night worker is essential not only for safety but also for meeting all legal and preventive requirements.

This article provides a clear, practical overview.

Why Is It Important to Correctly Identify Night Workers?

Increased Health Risks

Night shifts disrupt the circadian rhythm, increase fatigue, impact sleep quality, and may contribute to long‑term health complications.

Legislative Obligations

By classifying employees as night workers, employers automatically assume specific responsibilities, including mandatory medical checks for night work.

Employer Responsibility

Correct classification is key to ensuring that employees receive appropriate assessments and that employers meet all legal requirements related to night work.

When Is an Employee Considered a Night Worker?

Regularly performs at least 3 consecutive hours of work between 22:00 and 06:00.

Night workers are subject to different rules than employees who only occasionally work at night.

What Is NOT Considered Night Work?

occasional
random
one‑time

Performing a small portion of work during night hours does not qualify the employee as a night worker.

Mandatory Medical Examinations for Night Work

Initial Medical Examination

Before assigning an employee to night work, every worker must undergo an initial medical check focused on fitness for night work. Its goal is to confirm the employee's ability to safely perform night work.

Regular Periodic Examinations

Employees working night shifts must regularly undergo periodic medical examinations, usually once a year, to detect early health changes or risk factors caused by night work.

Assessment of Health Limitations

If a doctor identifies a health condition that may limit or prevent night work, they can recommend adjusting working hours or transferring the employee to day shifts. The employer is required to follow the doctor’s assessment.

How Can an Employer Prevent Health Risks from Night Work?

Regular assessment of the work regime – technical, technological, and organizational measures should be reviewed and improved to reduce risks associated with night work.

Cooperation with occupational health services – professional monitoring helps detect reduced fitness for night work early—ideally during annual examinations—so preventive actions can be taken.

Education and prevention

Night work represents an increased physical and mental burden, which is why correct identification of all night workers and timely medical examinations are essential. Proper classification ensures protection of employees’ health and helps employers meet all legislative duties without stress.

If you need assistance with process setup or evaluating current solutions, we’re here to help.
