Top Requirements for Dust Extraction Systems
Posted on July 20th, 2016
Any industry that involves welding and woodworking should take a look at some of our latest dust extraction and ducting technology to ensure they are following best practices.
Processes like sanding, milling, cutting and turning creates wood dust and particles that become airborne. Welding fumes are also a potentially fatal health hazard.
The major hazard when it comes to wood dust is, of course, breathing it in, however, a lot of particulates in the atmosphere can also create a potential explosion problem along with product quality can be affected.
Here at BenchVent, we have invested heavily into research and development to ensure our customers to the very latest and best dust extraction and ducting technology available to them.
To help keep workplaces free from toxic welding fumes and wood dust, we have a number of proven solutions, such as downdraught benches and benchtop extraction cabinets that can make your working environment much safer. We have a range of ducted models that extract to the atmosphere and several filtration units that provide at-source filtration.
If you are unsure which best suits your needs please contact us.
What are the requirements for Ducted Dust Extraction Systems?
- The air required at the dust extraction hood must be of adequate volume and velocity to capture the waste product produced during manufacture
- The speed (conveying velocity) required to move waste material through the ductwork must be high enough to ensure that the material does not fall out of the airstream onto the floor of the ducting, causing blockages in the system and bringing production to a halt. In factories that work around the clock, this is extremely important.
- The actual type of dust collector used in the workplace is exceptionally important. Basically, the correct selection of dust extraction system for the job is of critical importance, both to the worker and to the company. If you get it wrong you may be putting employees in more danger than previous.
- The fan in the extraction system must produce the adequate air volume overcome resistance to airflow.
Industrial Dust & The Human Body
Sometimes we get caught up in the mechanics, regulations, and safety of why an industrial dust collection system is needed. Other times we are concerned with combustible dust and it’s dangers, but what about the effects of dust on the human body.
Whenever people inhale airborne dust at work, they are at risk of occupational disease. Year after year, both in developed and in developing countries, overexposure to dusts causes disease, temporary and permanent disabilities and deaths. The Health & Safety Executive (HSE) offers documents to help educate and train people and employers in the prevention and control of dust in the woodworking environment.
Irritant dust can settle in the nose and may lead to inflammation of the mucus membrane as well as inflammation of the trachea or the bronchi. According to the Canadian Centre for Occupational Health and Safety, “The lungs are constantly exposed to danger from the dusts we breathe.” The most dramatic dust reaction of the lung occurs in the deepest parts of the organ, leaving scarring and impaired normal lung function. The amount of dust particles that settle in the lung also effects the capacity of the lung and the ability to take full deep breaths. Many lung diseases are caused by inorganic dust exposure to silica, tin, tungsten carbide and coal. Even organic dust such as hair particles, hay, and dust of heat treated sludge can cause a disease to the lung.
The eyes are not immune to the effects of dust particles. Even most safety glasses allow small dust particles to reach the eye causing irritation and/or possible damage to the cornea. The HSE has certain standards in place to limit exposures to specific dust and fumes.Inhalation of cobalt metal, dust and fumes may cause interstitial fibrosis, interstitial pneumonitis, myocardial and thyroid disorders, and sensitization of the respiratory tract and skin. Some diseases of the heart have been linked to dust and fumes.
