Silica Dust in the workplace
Silica is a natural substance found in concrete, bricks, rocks, stone, sand and clay.
Without the relevant protective measures, the smallest of dust particles are breathed in. In the worst cases, these penetrate into the lung tissue, the alveoli, where they cause severe damage.
TAKE NO RISKS!
It is important to eliminate silica dust from a workplace or control any exposure to ensure worker safety. Silica is a known contributor to lung cancer. At least 600 – 900 people die a year form occupational health disease in New Zealand.
Exposure to RCS is a workplace hazard that employers must eliminate, isolate or minimise.
Employers have a legal duty to take all practicable steps to ensure employees are safe at work. Employers may also have duties to other people at or in the vicinity of the workplace.
Avoidance of dust development through the use of the highly efficient Starmix Dust Extractors.
The Starmix Dust Extractors remove dust particles directly from the danger zone.
DO NOT FORGET: FINER IS MORE FEARSOME
The general rule is: the finer the dust, the greater the health risk.
Therefore, different particle sizes have different dangers:
- < 10 µm Reduces lung function
- < 2 µm Skin and eye ailments
- < 1 µm Tumors
- < 0,1 µm Heart and lung diseases
All dust classes at a glance.
Dust class L (light)
These dusts have an occupational exposure limit value (AGW) of > 1mg/m³. The filter material of vacuum cleaners of dust class L is tested. The maximum particle penetration grade is less than 1 %. There are no special disposal requirements.
Dust class M (middle)
Here, dusts with an AGW of > 0.1 mg/m³ are present. These vacuum cleaners are tested as complete units. The maximum particle penetration grade is less than 0.1 %. Disposal must be carried out low on dust.
Dust class H (high)
This dust class covers dust with an AGW value of > 0.1 mg/m³, all carcinogenic dust and dust which is tainted with pathogens. These vacuum cleaners are also tested as complete devices. The maximum particle penetration grade is less than 0.005 %. Disposal must be carried out free of dust.
Dust class H - Asbestos
This class corresponds to dust class H. The difference: an additional test for machines and devices that eliminates dust and is intended to collect and separate asbestos
