What is the function of a fire damper?

What is the function of a fire damper?

The fire damper secures the integrity of the existing barrier thus preventing fire penetration before temperatures reach the fire rating level of the barrier itself. Its primary function is to prevent the passage of fire from one side to the other of a fire-rated separation.

How often do you test fire dampers?

every 4 years
NFPA 105(10), Sec. 6.5. 2 requires that each damper be tested and inspected 1 year after installation and that the test and inspection frequency then be every 4 years, except for hospitals, where the frequency is allowed to be every 6 years.

Is fire damper testing statutory?

Under the Regulatory Reform (Fire Safety) Order it is a legal requirement to test fire dampers at regular intervals in accordance with fire safety in the design, management and use of buildings code of practice (BS:9999 2017), using a method known as ‘drop testing’.

What is the function of damper in suspension system?

A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.

What is fire damper maintenance?

According to the BS 9999 fire damper legislation, you must ensure that your fire dampers are repaired or replaced immediately if found to be faulty. It is highly recommended that you create a maintenance plan to help you budget and schedule repairs, ensuring your fire dampers remain in a fully working condition.

How does damping work?

damping, in physics, restraining of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipation of energy. Unless a child keeps pumping a swing, its motion dies down because of damping. Shock absorbers in automobiles and carpet pads are examples of damping devices.

How important is testing your fire dampers?

1. Fire dampers are a key component of a building’s fire safety system. It is important that they are tested regularly to ensure that they are in the best condition to do their job and work effectively in the event of a fire. Yet, a large number of building owners are still unaware if they even have fire dampers installed in their properties.

How often do fire dampers need to be inspected?

Then, each fire damper must be tested and inspected one year after the installation. After that one year mark, fire dampers must then be tested and inspected every four years except for hospitals which have a six year frequency.

Is a fire damper or a smoke damper is required?

Fire smoke damper installation is required for all Heating Ventilation Air Conditioning (HVAC) Systems. To inhibit unforeseen accidents due to fire and smoke, the dampers are installed to interrupt the passage of flame, smoke, and heat. Well, it cannot be denied that fire smoke damper installation seems to be a single installation process.

What is a fire damper service?

A Fire/Smoke Damper is a very important element of passive fire stopping in a building. Coupled with other elements of a passive fire system, a correctly installed Fire/Smoke Damper will compartmentalise an area, impeding the spread of Smoke, Toxic Gases and Fire throughout a building. Effectively, this will increase the time available for evacuation of the building and for fire services to extinguish the fire and minimise the damage to the property.
