Fire dampers are passive fire protection products used in heating, ventilation and air conditioning (HVAC) ducts to prevent the spread of fire inside the ductwork. Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperatures higher than ambient but low enough to indicate the presence of a fire, a

We all saw or heard of the fire that broke out at the East Rand Retail Park in Boksburg. “The fire started in Coricraft, and then jumped to other stores like Adidas, Tekkie Town and Jam,” said Eric Maloka, Ekurhuleni metro’s disaster and emergency services spokesperson. The last thing any business needs or wants is for it to go up in flames. This is why there are very strict Regulations when it comes to fire safety and protection against fire in any building in South Africa,

The Curvent Fire X Vertical fire ventilator is a louvre bladed vertical mounted fire ventilator. The Fire X Vertical louvred blades are designed to close individually over each other, providing a waterproof system in the closed position. In the event of fire, the spring loaded louvred blades open automatically to allow hot gasses to exhaust. This will aid in the buildings structural integrity against collapse. We have just installed a 110 of these FXV Electro Mechanical Units

The smoke ventilation system at Grenfell Tower was reported to have failed eight days before the fatal blaze claimed 71 lives, but a proposal to fix it for £1,800 was ignored, the public inquiry has heard. The failure of the ventilation system, designed to extract smoke from lobbies outside flats in the event of a fire, has been identified by experts as a factor in the escape routes from the building filling with thick black smoke that may have prevented evacuation and rescue

Summed up it is a process of redirecting smoke and fumes in order to save lives and assets. The advantages of smoke control systems The first advantage to specify and install smoke control systems are to protect escape routes and to assist firefighters in the event of a fire. Another advantage of smoke control systems is that stock and machinery can be protected and the risk of loss of the building (perhaps due to roof collapse) can be reduced. Smoke ventilation systems utili

Fire needs three basic elements to start; Fuel Oxygen Heat Source This is called the ‘Fire Triangle’. If anyone of the three elements is missing, fire will not ignite, or, if it is already burning, removing one of the three will quench the flames. The fire can be brought under control and/or can be quenched, if one of these elements is taken out of the ‘Fire Triangle’. Example: Remove the oxygen and the flames go out. This is often what is being done when we talk about exting

Industrial ventilation systems are designed to move a specific amount of air at a specific speed, which results in the removal of undesirable contaminants. Industrial ventilation systems are specifically used in: Production factories & - plants Mines Control rooms, machine rooms and offices Laboratories Electrical rooms, cable spaces and automation rooms Every ventilations system are specifically designed for the individual operating environment. Since 1984 Curvent Internatio

Without the correct sources of inlet air, your ventilation system will not work effectively. If you are trying to extract air from a factory without replacing the air/smoke that you are trying to extract nothing will move. This is called a vacuum and that is why you need an expert to determine the number of air inlets into a building. It's simple for air to come out, air must come in Without insufficient air inlet into a factory carbon monoxide can build up and temperatures

South Africa's building regulations emphasis smoke control for safety reasons. A well-designed smoke control system should always provide for a smoke-free escape to allow for the minimum risk of smoke inhalation, injury or death. Curvent International has considerable experience in the design and implementation of smoke control systems in Shopping Centres and Car Parks across South Africa With over 100,000 people in one day visiting some of the largest Shopping Centres, the b

Multistory above and below ground car parks are becoming more common due to increased public reliance on cars as well as the congestion in towns and cities resulting from higher population densities. Motor vehicle engines running within an enclosed space will result in poor air quality and the confinement also increases the potential threat of smoke inhalation in the event of a fire. It is essential to ventilate covered car parks in order to limit users to the harmful effect

We mentioned in a previous article that all ventilation systems requires inspection and testing. Training on routine and emergency operating procedures should also be provided and all three these elements should be incorporated into a good ventilation control program. Let's discuss these points separately: Inspection Never assume the system is operating properly just because the fan is running. Some things to be considered during inspections are: Determining the velocities at

All ventilation systems require inspections and testing. Training on routine and emergency operating procedures should also be provided. We can help you to incorporate these into a ventilation control program. Some factors to be considered and incorporated into the program are: Written standards and procedures for operation of ventilation systems Regular daily or weekly inspections, depending upon the toxicity of substances to be exhausted Regular clean-out schedules for set

Depending upon workplace conditions and activities, the hazards of poor or no ventilation could include: 1. Lack of oxygen. Symptoms can include headache, fatigue and asphyxiation, particularly in confined spaces 2. Excessive heat, cold, and humidity. Any one of these could hinder your production 3. Toxic fumes for e.g., lead, cadmium, zinc and toxic vapours like benzene, toluene, trichloroethylene, MEK 4. Toxic gases for example hydrogen sulphide, ammonia 5. Dusts that can c

Is your building or factory in need of an upgrade? Do you need to renovate to increase your productivity? It may become necessary, because of changes in plant layout or processes, to make additions or renovations to the ventilation system. Before doing so, seek expert advice. What may seem to be minor alterations or additions can seriously impair the functioning of the entire ventilation system. If ventilation is required to keep the exposure limits to below the Legislative O

Fire curtains are curtains that prevent damage and threat from heat and smoke in the event of a fire. They come in all shapes, sizes, and materials and are found in commercial, public and domestic properties.
