Demolition work
Alterations Chiselling, grinding, milling Plaster work Stripping old plaster Compaction work Mixing dry mortar Recycling plants for building materials Jet blasting Cleaning work
High exposure to dust in construction industry
Session 32 – Good Practices
Dipl.-Geogr. Norbert Kluger
Angle grinder without dust extraction / wet sawing
equipment without vacuum cleaner existing technical measures insufficient

Legal requirements (Germany 2006)
Threshold limits:
Respirable dust fraction (E-dust) 10 mg/m³
Alveolar dust fraction (A-dust) 3 mg/m³
Alveolar silica dust 0.15 mg/m³
Since July 2005 alveolar silica dust has been classified in Germany
as carcinogenic. Therefore the threshold limit was set out.

What is the situation on construction sites ?
Some exposure data:
Dry cutting Wet cutting
Respirable dust 169.00 mg/m³ 54.97 mg/m³
A – dust 29.80 mg/m³ 6.37 mg/m³
Silica dust 3.89 mg/m³ 0.63 mg/m³
Cleaning work
Respirable dust 23.80 mg/m³
A – dust 5.13 mg/m³
Silica dust 0.23 mg/m³

Low-dust machines are commercially available
Clean solution: Modern machinery such as hammer drills with integrated dust extraction provide good services even when working overhead.
Session 32 – Good Practices
Dipl.-Geogr. Norbert Kluger
Practice-orientated research project
Clarify the question: How effective are the currently
available systems in dust collection ? Approx. 100 commercially available processing
systems (electric power tool and mobile vacuum cleaner) have been tested.

Testing hand-held machines and equipment
using standardised criteria that have been agreed with the manufacturers
each machine is tested 3 times
on average, one machine per day
tested on selected materials

Key message
Consider a certain system in the practical situation!(do not use just any exhaust system / vacuum cleaner you like)
Use only matched systems! (matched system = machine + vacuum cleaner recommended by the producer)
What technically is possible,
is seldom found in practice!

The future: Change the work process
… only with extraction !
Not like this …

The way: Develop a “Sector-specific solution”
Sector-specific solutions are recommendations developed for implementing specific hazardous
substances regulations across an industry sector
Such solutions should be developed with the collaboration of employers and employees, the health and safety inspectors,
the accident insurance institutions (BGs) as well as other institutions.

Agreement between all partners in the construction industry
Guidelines for use in practice
Our experience: Effective Sector-specific solution

A package of measures shall fight the “cement dermatitis” effectively
The beginning of the end - initiatives would lead to a European-wide ban
Our experience: Effective Sector-specific solution
