When a workplace has an environment or processes that produce a fair amount of dust and other airborne material, it makes sense to protect the health of its workers by installing dust extraction units. Dust, when constantly inhaled, can lead to respiratory diseases and this can affect the health not only of the workers around machinery, but may also affect the surrounding environment. This is especially true in the case of large construction projects, and project managers have to take care to control this in the best way they can.
The type of dust extraction units can depend on the size of the units producing dust and the type and volume of dust created. In most such cases, it becomes necessary to workers to wear face masks or other breathing devices, and other measures like wetting the dust to enable it to be trapped. Many drilling machines are equipped with water sprays that prevent the dust from rising, and enable it to be trapped in to slurry that can then be conveniently disposed of. In many processes, other chemicals and fumes may also be produced that can harm health, and these also need to be extracted and carried away for treatment or to be rendered harmless after treatment.
Common dust extraction units will be composed of exhaust fans that allow dust and fumes to be extracted from a work place. These will function better, if simultaneous arrangements are also made for ventilation, so that fresh air can return to the work space. An effective system for cleaning air has to be conceived of during the installation of any machinery for fabrication or manufacturing that will produce, dust, fumes or heat. This requires proper design of the work space, with respect to its total volume, the number of people working within it, and the particles that any work process will produce.
A proper dust extraction system will first act to confine the dust to a particular space, before it can be extracted. This can be done by installing hoods that can capture the material, and must be positioned according to the throw of the machine that produces the dust. The objective has to be to confine the dust or other particles to a definite area, where they can be captured until they are extracted by the unit.
Most dust extraction units capture the dust in a hood, and then convey it out of the working environment to places where they can be further treated for rendering them harmless. In many cases, these units are fitted with filters that capture the offending dust, so that what passes through the unit is air that has been rendered harmless. It then becomes very important to see that these filters are constantly cleaned so that they can continue to capture the dust efficiently. In many processes, such dust can be valuable and may contain chemicals or other material that is expensive, and dust extraction units are then linked to recovery units, specially designed to collect the dust. You will find such units commonly used in processes where expensive coating material is used.
The installation of dust and fume extraction units requires attention to be paid to their constant maintenance and cleanliness, so that performance never reduces and leads to health hazards. They must also be assured of constant ventilation, as otherwise the extraction may not be as efficient, as required. Air qualities must be constantly monitored to ensure that the machinery is working as it should. Proper attention to dust extraction is a part of worker’s safety and can never be neglected. It can also lead to better productivity and higher efficiencies of equipment.
