Passive Measures
1. FIREWALLS AND PARTITIONS
Firewalls are designated for the separation of rooms of different functional fire hazard classes, as well as for separation of productions of different fire hazard categories. Firewalls shall be designed with a fire resistance class REI 60 (or EI 60) and shall be made of construction products with a reaction-to-fire class not less than A2. The openings in the fire protection walls shall be designed with a total area not exceeding 25% of the area of the respective wall. Doors and shutters for openings in fire-proof walls are self-closing and fire-resistant class EI 60. Horizontal fire barriers are intended to limit the spread of fire in a vertical direction. They shall be designed as floor, ceiling and intermediate structures made of construction products with a reaction-to-fire class of not less than A2 and with a fire resistance class of at least REI 60. The openings in the horizontal fire protection barriers shall be protected by automatic fire-proof closing devices with fire resistance class at least EI60 which also block the operation of the facilities passing through them. It is permitted that the total area of openings in the horizontal fire barriers to be up to 2% of the area of the barrier.
2. CHIMNEY SYSTEM
Regulation No Iz-1971 of 2009 on construction and technical rules and standards for ensuring fire safety stipulates the requirements for the chimneys of buildings. In this regulation Art. 127 to Art. 136 describe in details the requirements for the chimneys in a building which are often purposely neglected and as a result the construction output have hidden deficiencies. Such constructions are fire hazardous and the risk of a fire is vastly higher than those in which fireproof, energy efficient and environmentally friendly chimney systems are used. What is even less known to the general public is how serious the consequences of improperly built chimney ststems could be.
3. EVACUATION PLAN
The main purpose of the evacuation plan is to prevent panic, chaos and riots from occurring during evacuation from a building. When we have a clearly defined and well-practiced evacuation plan, it could be ensured that the building is safely and orderly left and that it is possible to count the people who have successfully evacuated. Part of the components of the evacuation plan include placing signs to help guide people to move within fire-safe walls and floors, corridors leading to safe exits, supplying the building with an emergency staircase to when it is required by Regulation № Iз-1971of 29.10.2009 on construction and technical rules and norms for for ensuring fire safety. These components are the main means to guide people in a building what action to be taken in case they need to evacuate. In case of fire, accident or disaster, the decision-making time is a key factor on which your life may depend on, so take the time to acquaint yourself with the evacuation plan in order to react and make the right decisions in a timely manner.
