What is construction vacuum cleaner

Fine dust on construction sites

Construction dust is a general term that describes the types of dust that typically occur when working in the construction industry. If not properly controlled, they can seriously affect your breathing and damage your health. The new wet and dry vacuum cleaners from Kärcher are characterized by improved filter technology, which helps to control the dust around you and to protect you and others from it.

What is construction dust?

Construction dust is a general term that describes the types of dust that typically occur when working in the construction industry. These dusts are not only annoying. If not properly controlled, they can seriously affect your breathing and damage your health. With prolonged exposure, some types of dust can cause life-threatening lung diseases and even death.

We know about the fine dust particles floating in the atmosphere every day, such as human skin cells, textile fibers and actually also burnt meteorite particles. However, construction workers are faced with much more dangerous types of dust.

There are three broad categories of dust that are created when cutting, filing, grinding or other breaking up of materials:

 

Fumed silica

Concrete, bricks, tiles, mortar and sandstone (also known as "respirable crystalline silicate" in English)

Wood dust

Softwood, hardwood, and wood products such as MDF and plywood

Dusts with lower toxicity

Gypsum (e.g. in plasterboard), limestone, marble and dolomite

What dust do you breathe?

  • Quartz and asbestos dust
    • are particularly dangerous and can cause cancer.

  • Toxic or carcinogenic dust
    • of lead, cadmium, vanadium or manganese not only damage the lungs, but also other organs such as the liver or spleen. Dust of this type arises among other things. when welding.

  • Wood dust
    • For example, oak and beech can cause nasal cancer in the long term.

  • Allergenic dust
    • is usually of vegetable or animal origin and occurs e.g. B. when cleaning work on or in buildings that are contaminated with bird droppings. Molds and microorganisms can also cause allergies.

  • Fibrinogenic dust
    • leads to the formation of scars and, after frequent exposure over a long period of time, to a progressive remodeling of the lung tissue. Dust infections caused by quartz and asbestos are among the most common recognized occupational diseases.

Then submit the invoice & request for reimbursement to BG-Bau. As soon as the application is approved, you will be reimbursed the specified portion of the purchase price.

Avoidance is always the best protection

Dust that does not arise in the first place cannot endanger anyone. There are many ways to avoid dust. And if we cannot avoid it, then we can tie it up, suck it off or block the way into our lungs with protective clothing and respirators.

What you can do to avoid dust:

 

  1. Extract dust as it arises.
    Many power tools have nozzles for connecting to a vacuum cleaner. Vacuum cleaners with connection sockets switch on automatically when the connected power tool starts. Always use a suitable filter.

  2. Low-dust work processes insert, e.g. B. wet or damp machining.

  3. Bind dust with water, z. B. during demolition work and grinding work outdoors.

  4. Use low-dust products, z. B. Mortar pellets, ready-mixed concrete and finished plaster.

  5. Avoid unnecessary stirring up of dust. Instead of dry sweeping and blowing, it is better to use vacuum cleaners and vacuum sweepers.

  6. Preventive occupational medical examinations initiate and use.

  7. Jobs clean regularly, Workrooms ventilate sufficiently,Workwear keep clean.

  8. Remove waste immediately and free of dust.

  9. Regularly check the suction performance of vacuum cleaners. Clean or replace filter as required. Use vacuum cleaners with automatic filter cleaning for consistently high suction power.

  10. Wear protective clothing and respirators. A matter of course for dust-intensive activities, but you should always wear at least suitable respiratory protection even with less dust exposure.

Security is a "tact" issue

We want to help protect workers in the construction industry from the dangers of fine dust. That is why we have developed a range of vacuum cleaners that can pick up wet and dry dirt and dust - optionally directly at the dust source using chip and dust extraction. With our latest generation of wet and dry vacuum cleaners in the Tact H and M classes, we have gone one step further.

What does “Tact” stand for? Triggered Air-draft Cleaning Technology

With a multitude of functions such as our new sensor-controlled, automatic filter cleaning system (Tact), Kärcher Professional dust and dry vacuum cleaners recognize when the flat pleated filter needs to be cleaned - then they briefly reverse the air flow and blow air through the filter. The user can therefore work without interruption without any loss of suction power. This revolutionary system leads to unprecedented amounts of dust that can be extracted without manual filter cleaning and to significantly less noise pollution when only small amounts of dust occur.

Due to this highly efficient filter cleaning, the powerful Tact vacuum cleaners are suitable for both typical and dangerous dusts. The filters have a unique service life of 180 kg of fine dust (mineral dust category A). Only then do they have to be changed. At the same time, this means longer uninterrupted work with constant suction power and better protection against fine dust.

What do classes L, M and H stand for?

Dusts are divided into classes L, M or H, depending on the hazard level.

L class

Class L vacuum cleaners are particularly suitable for vacuuming softwood, lime and plaster dust or rubbish. L-class dust poses a moderate risk. No special precautionary measures are required for their disposal.

M class

The upgrade to the L-Class. Suitable for vacuuming dust and dirt generated by the following materials: hardwood, panel materials, paint dust particles, ceramics, concrete and brick. The M-Class is the lowest legally required class for use on construction sites.

H class

Class H vacuum cleaners are suitable for picking up large quantities of safe and dangerous / highly carcinogenic substances such as asbestos dust, lead, coal, nickel, cobalt, copper, cadmium and mold.
