About Mechanical Smoke Ventilation Systems

The integration of smoke-control systems have the ability to improve the safety of buildings significantly. Smoke ventilation systems are available in various forms and vary widely when it comes to complexity. For example: there are mechanical smoke ventilation systems, pressurization systems as well as natural-smoke venting. Regardless of the type of system, it is recommended by fire risk assessment Kent company, the Fire Risk Assessment Network, the objective basics are all the same and will include the following:

  • To make sure that escape routes are kept free from any smoke
  • To remove or contain smoke form an area experiencing a fire in order to prevent the smoke from moving into other areas
  • To accelerate fire-fighting operations
  • To minimize property loss and protect lives


Mechanical Smoke Ventilation System


How An Mechanical Smoke Ventilation System Works

The MSVS (Mechanical Smoke Ventilation System) acts effectively as a type of depressurization system. The system extracts heat and smoke out of an area which results in depressurization of the space. Due to the fact that surrounding areas like staircases have higher pressures, the air will be forced out of these areas and directed towards the smoke shafts preventing smoke from migrating into the staircases and the neighboring areas.

However, it is essential to stipulate that there is an extra inlet of air to a space that is depressurized in order to stop the space from becoming over depressurized. When a room becomes too depressurized, the smoke-venting equipment can become damaged and the pressure differentials that occur across the doors can cause the door handles to become difficult to pull open between the fire area and depressurized room.

The make-up of inlet air for these systems can be achieved in various ways and will be dependent on the layout of a building. Below are the 4 common methods used to achieve an air inlet:

  • Natural inlet of air through an AOV positioned at the top of a staircase
  • Natural inlet of air through external air
  • Mechanical inlet of air through a shaft
  • Natural inlet of air through a shaft

MSVS In Residential Buildings

The foundation of smoke-control systems in residential buildings is to stop smoke from moving into the area of a staircase in order for the occupants to escape from fires unhindered. In addition, this can ensure that fire services can have a protected and clear access to the source of the fire.

As an MSVS pulls smoke and heat from a common lobby or corridor that is not dependent on the buoyancy of natural smoke, the “shaft” area is significantly minimized when compared to natural systems. The area of a smoke shaft on a MSVS will depend on a number of factors like the size of an AOV opening in the shaft, the extraction rates of a fan, fire loading in the next room as well as the size of the lobby or the corridor. Once all these factors are taken into consideration the shaft area on the MSVS will typically range between 0.25m2 and 0.6m2. Fire engineers are able to provide the correct guidance in this matter.

Getting a Good HVAC Electrician Service Is A Must!

All About Local Exhaust Ventilation Testing

If you find yourself scratching your head for a reason to clean and maintain your Local Exhaust Ventilation (LEV) system, you need to know that you are actually required by law to make certain your LEV system keeps working correctly. Of course, you are NOT required by law to do it every month. That said, you should do periodic testing on your LEV.

In our experience, local exhaust ventilation systems are the most prone to breakdowns. Certainly one of primary explanations why LEV does not do what it really should happens because the air flow falls for some reason or another, the parts break down and efficient control are lost.
By testing your exhaust ventilation for air flow, parts breakdown, and efficient control, you can stop problems before they even start.

How do you do local exhaust ventilation testing? One easy method of checking this is actually the utilization of air flow indicators in the ventilation system. By simply checking the indicators, your air flow rates are maintained, and your workers are protecting. You will find different tools of checking air flow, for example, using anemometer, or perhaps a dust-light or smoke tracer. However, an air flow indicator is present in most ventilation systems.

How do you know that the LEV air flow is sufficient?

It’s not easy to gauge effectively the rate or velocity of the air entering an LEV hood ‘by hand’. A appropriate air flow indicator helps it to be easy to understand whether air flow is sufficient.

It’s not a legal requirement, but you ought to have a way of making sure that sufficient air flow has been maintained. If you choose to get air flow indicator tools, you need to identify which LEV systems or areas of the system have to be addressed first. LEV providers can fit air flow indicators if you ask them for it.
Are air flow indicator tools the easiest method to check air flow for all sorts of LEV systems?

It depends on the LEV system. For example, a manometer, which calculates static pressure over the filter unit, can offer sufficient indication, is sufficient for a simple LEV system composed of a fan, filter, a duct, and a hood.

What kind of air flow indicator ought to be fitted to your local exhaust ventilation?

It is dependent on the amount of potential health problems. If risk is low, a simple indicator is going to be appropriate. However, if your system handles hazardous substances and conditions, you need modern-day, and potentially more pricey, indicators that have advanced features, like sounding an alarm if air flow drops. But regardless if you’re buying a cheap model or a more expensive one, make sure it exhibits clearly if the air flow is sufficient.

Wouldn’t air flow tell-tale signs be great enough? Tell-tales signs like bits of plastic or paper hung to bend within the LEV hood air flow, don’t offer an effective symbol of air flow. In most simple systems that deal with hazardous substances, they’re not going to work and neither are they sufficient or appropriate.

Do investigators need to label LEV systems they test? No – there’s no specific legal requirement on companies or investigators to label tested systems. What the law states is that the employer must maintain a system level performance and also arrange an intensive examination and test a minimum of once every three months or so.

You and your administrators and operators must know when a test is going to be done or when it is due. More important, they should also know when a ventilation system is not working properly.
