Protecting the health of people, who work in dusty environments, is an indispensable requirement. Dust, such as wood or flour dust, can be harmful and at worst inclined to an explosion!
Health Hazards – Working in a Dusty Environment
Working in an environment with machinery, that processes dry material, can create harmful dust. Wood dust, for example, can cause skin, lungs and eye irritation (http://www.hse.gov.uk/woodworking/wooddust.htm). The smallest particle of wood dust, from cutting or shaping wood, can be very dangerous to a worker: Microscopic dust particles can enter the pores of the skin or settle deep into the lungs; causing irritation, rhinitis, asthma or even cancer!
Moreover, hardwood dust exposure, a carcinogen, should be eliminated as far as possible; in reasonably practical limits and at least within the legal Work Exposure Limit (WEL): 5mg/m-3.
High-quality dust extraction systems can have positive effects on both the tidiness of your workplace and the health of your workers. Masterflex produces polyurethane hoses and ducts for use as flexible connectors in dust extraction systems.
Fires & The Risk of Dust Explosion – Antistatic Ducting & Hoses
The First Explosion
As dust particles travel, through non-antistatic/non-electroconductive plastic hoses/ducting, they can build up a static charge. If naked flames or sparks come into contact, with the charged dust particles, they could produce flash fire; these flash fire particles can cause an explosion. In other words, dust contained within an enclosure, such as within a duct or silo, builds pressure; and therefore creating a destructive blast.
The Second Explosion
The pressure from the first explosion can throw dust deposits, creating dust clouds, around the work area. These dust clouds, if ignited by the first explosion, would result in a secondary explosion; which can be more destructive than the first!
Therefore, it is vital to keep your work area as dust free, as much as possible, to prevent an explosive mixture; efficient extraction at source is the most effective method of reducing the hazard of dust.
The elimination of static build-up, when transporting dust through hoses/ducts, is of crucial importance. It is also critical to have efficient dust extraction at the source, by preventing dust buildup in ducting, using smooth bore hoses.
Dust Extraction Hoses: Here at Masterflex Technical Hoses Ltd, (Masterflex UK), we understand the importance of having safe and efficient extraction of dust at the source; and strive to supply the best quality dust extraction hoses to a variety of industry; including dust extraction for woodworking machinery. Dust extraction hoses, which fully comply with the ATEX European Directive for explosive hoses, are manufactured provided by Masterflex UK.
