Not only is dust a major factor requiring control on site, it is hazardous and a real health issue when not treated correctly. Two of the biggest concerns are silica dust and asbestos contaminated material. More information on both of these can be found on the HSE website.
Although 100% prevention is almost impossible, there are numerous ways to limit the effect of dust.
- Adequate dust extraction
- Additional air scrubber
- Appropriate PPE
Firstly, all of our equipment is compatible with at least one of our range of dust extraction units. We run an array of sizes, which are available with or without Longopac debris bags, as well as 110v and 415v versions.
Dust extractors which take the Longopac debris bags are most popular with our asbestos demolition contractors, as the dust is immediately contained and easily tied off, ready to be disposed of appropriately. Alternatively, our bin style dust extractors are most popular with our concrete form work contractors, and domestic customers. However, even our customers that primarily work externally will also always hire a dust extractor to work alongside the main machines.
It is a common misconception that if you’re working externally, you won’t need dust extraction.
Although the elements will have a certain level of effect on the level of dust, the operative using the machine will still be in too close a proximity for the wind to mitigate it completely. In addition, we are often asked if grinding or scabbling wet is better than dry. Adding water to the area you’re working on will help to combat the level of dust, but you’ll then be left with a slurry to clear away. Although you can use our machines wet, they’re primarily set up to use dry, as we deem this the safest and cleanest course of action.
Air Scrubbers are also a useful tool, which can be used in all sized areas. We run the Ermator A1200 which are specialist air dust filtration machine and are designed to filter any remaining air borne dust, into reusable clean air. We also advise hiring a Wand & Floor Head with your dust extractor, as these help clear up any remaining surface level dust.
How often do I need to clean the filter?
This is a majorly key point, that many people often overlook. All of our dust extractors are designed with a filter cleaning mechanism to help maintain its productivity whilst on site. How often you need to do this, is often relative to the type of floor you’re working on. If you’re grinding an especially soft concrete, you will need to clean the filter more regularly, so it can keep up with the rate of dust that is being created.
How durable are the hose attachments?
All of our dust extractors are fitted with specialist anti-static, heavy duty hose. This is to add another level of protection for the operative, but they aren’t designed to be driven over by a stray scissor lift!
How else can I limit the effect of dust?
It is essential to ensure the dust guard on the machine is sitting correctly on the floor. Occasionally, if someone on site has altered the angle of the machine, it can create gaps around the bottom, leaving space for dust to escape. In addition, ensuring you have a well fitted face mask is paramount. Dust particles can be smaller than a strand of hair, so you really do need to make sure your mask fits perfectly before commencing work.
Why should I hire from Concept?
As with our previous blog posts, we can prove that were not like every other hire company out there. We care about our customers, and take these matters seriously. To ensure our dust extractors are ready for hire, they go through a strict cleaning, servicing and testing process in our workshop. As part of this, our workshop is equipped with heavy duty downdraft benches. If you’re unsure which dust extraction unit will be best suited for your job, we are always more than happy to advise.
