Fire protection is separated into two categories: active and passive. Each system offers a distinct approach to fire protection, but both are vital in ensuring the highest standards of fire safety are met. This article will be highlighting the differences between active and passive fire protection.
What is active fire protection?
Active fire protection is a system of equipment and components that safeguards through action.
Active fire equipment possess an active state and a latent state. A manual or automatic trigger is required to activate the equipment, bringing it out of its latent state and into its active state. Once active, these components aim to eliminate the blaze. This may be achieved indirectly, such as an alarm alerting people of the fire and prompting them to take action, or directly, by releasing a liquid or foam that attempts to extinguish the blaze.
Active fire protection in its latent state offers no defence against fire. A sprinkler with dead batteries, or an extinguisher that is never squeezed, offer no protection against an ongoing fire. It is only when they are activated as a result of a trigger that protection is provided.
What is passive fire protection?
A Passive fire protection is the components of a building's structure that reduce or prevent the movement of fire.
Passive fire protection does not seek to extinguish a blaze, merely to prevent it from spreading and causing further harm. This is achieved through compartmentalisation and fire-resistant materials.
Manual Vs Automatic Fire Protection
Examples of passive fire protection:
Reduces the amount of oxygen that leaks into a room.
Rire protection coating protects electrical cables.
Fire protection coating for walls and other applications.
Strategic structural placement prevents a fire spreading.
Prevents fire spreading through ventilation and air conditioning ducts.
Possess fire-resistant materials and coatings that prevent the door from setting alight.
Glass remains intact and prevents fire from spreading.
Protects the structural frame of the building.
What is the difference between active and passive fire protection?
In summary, the differences between active and passive fire protection are as follows:
Should I use active or passive fire protection?
Active fire protection and passive fire protection work in tandem. Both types of fire protection should be implemented in every establishment to ensure the maximal levels of fire safety.
When a fire occurs, the smoke or heat from the blaze will trigger the fire alarm system. The fire alarm system becomes active and instantly communicates with multiple components. The sounder is triggered, emitting a loud noise to alert people of the fire. Once alerted, people can take suitable action, including tackling the blaze themselves with a fire extinguisher, calling the emergency services, or evacuating. Sprinklers will also be triggered, raining down water in an attempt to extinguish the flame.
Simultaneously, the fire-resistant walls will be preventing the fire from spreading, giving the active fire protection the best chance to tackle the flame. Fire doors, in addition to participating in compartmentalising certain areas, will enable alerted inhabitants to evacuate safely.
