Fire doors are vital when it comes to containment of smoke and flames in a structure that is on fire.
People may not realize that these doors are not just sturdy but they can definitely provide the true protection when subjected to the high temperature of flames, provided that they are properly maintained on a regular basis.
There are suppliers that are given license to sell these doors and consumers are advised not to buy from any store but only the certified ones if they need fire door replacement.
These doors are installed only after careful consultation and inspection with the governing bodies and upon recommendation by construction professionals.
The type of door to install would always refer to what the construction engineers and the building code inspectors have specified such as if the area would require 60 minutes of protection because it is a large area.
Some areas would only require at least 30 minutes protection by a fire-resistant door, so the building or house owner will look for an FD 30 specification on the door that they will buy.
It is important to coordinate with the building contractors and the proper agencies when you also want a fire door replacement of your ordinary door.
Through this consultation, you will be able to ascertain the other requirements so that materials would comply with one another.
It is understandable that a door that can withstand fires should be installed on a fire-proof door frame and walling as well, because otherwise, it doesn't make sense to have the other components around the door set to give in to burning a few minutes after exposure to fire.
Passive fire prevention systems are seriously taken into consideration when a building wants to operate.
Furthermore, the fire door does not function as the sole method for passive fire prevention but it can be used together with the fire extinguishers, fire and smoke alarms, fire sprinklers and emergency water hoses.
Doors that are fire proof can automatically close when the alarm is set off, once the sensors of these alarms can detect smoke or heat build-up in a certain location.
Indoor fires are dangerous because they can initially start with "cold smoke".
A fire-preventive door with no smoke seals can allow this type of smoke to pass through and imperil people from other rooms and spaces.
It is common for victims of indoor fires to have been reached by smoke first and they fainted before the flames have reached the place they have fainted on.
If the fire is put out quickly, then the unconscious building occupants can still be saved if they have not inhaled smoke too much.
On the other hand, should the inhalation be severe, the person can die and that would be another casualty for the lack of the proper passive fire prevention tools inside the building and also a deficiency on the part of fire rescue teams to carry out quick rescue.
This is the reason why fire doors are stringently imposed on buildings that are newly built and those that allow a large number of people to occupy the spaces at any given time.
