Top Challenges and Solutions for Fire Stopping NSW in Ducts

Ventilation ducts usually pass from one fire partitioning area to another. Duct Spray NSW provides proper fire protection in ducts. It also mitigates smoke and fire penetrations from spreading inside the remaining building.

Ventilation ducts are used in many facilities, whether for dust removal, or air quality management. In any case, fire stopping NSW within ductwork is a crucial consideration for firefighters.

A Heat Detector System in Ducts

Ductwork circulates heat, as well as oxygen, meaning that flames and smouldering materials can disperse conveniently within the duct system of a plant, rapidly affecting a wide area inside a plant. The duct systems are often as large as an area of tens of thousands of square feet.

Although fire codes dictate the location of duct alarms in many HVAC equipment systems, in industrial duct applications, the same precautions are also strictly voluntary.

Install rate-of-rise heat detectors within ducts or filter units for fire stopping NSW. If there is a sudden increase in temperature, the system will conduct a shut-down of blower fans; thus, restricting the spread and continued airflow in a fire incident.

Accumulation of Combustible Dirt

In industrial facilities, the ventilation systems are usually to transfer particulate matter within an airstream through a filtration unit. If this particulate matter is in the category of combustible dust, there is potential for an explosion within the duct system.

There can be an accumulation of such dirt in vents and coils of ductwork overtime. It obstructs the ventilation, and the system is stressed. If this causes overheating, the ventilation system may cause a fire to ignite and spread. Duct spray NSW is distinctly helpful in cleaning all these ducts thoroughly, thus preventing the fire hazards.

Back-Flow Dampers

In addition to the apparent firefighter threat, an explosion will transmit fire in the opposite direction to the normal flow of material, now transmitting fire and burning material to new locations within a plant that was not previously involved. Here, proper systems engineering to provide back-flow dampers will reduce the risk of fire and smoke travelling to the other parts of the plant.

Problems with Fire Suppression through Sprinklers

The implementation of fire suppression water (either via automated sprinklers or via manual hose streams) into a duct system will easily cause overhead loading issues. The purpose of duct supports is to support the duct when inside the structure there a minimum volume of accumulation. It would easily overwhelm supports and probably put ductwork down on top of workers by merely applying water to the ducts' interior without a suitable way of draining the structure.

It is better to provide access to hatches inside duct systems so that firefighters may easily reach the interiors of ducts and remove water without causing further harm. Otherwise, it will, eventually, create a more hazardous situation, as this is not a recommended procedure where combustible dust could be involved.

Conclusion

Without a doubt, proper engineering of duct systems can make or break fire stopping NSW tasks. Therefore, it is recommended that you get your ducts cleaned at least every two to five years with duct spray NSW.
