Sawing 300 mm (wet)

TNO has tested control measures for sawing 300 mm (wet) in sand lime blocks and concrete.

The hazardous substance management plan is as follows (in order of effectiveness):

Step 1: Choose quartz-Free / quartz-poor building materials.

Step 2: Choose to build PREFAB.

Step 3: Choose dust-free processes an tools.  

 

TNO has tested one dust-free process for sawing 300 mm (wet). The test specifications are a space volume of 15 m3, ventilation of 150 m3/h and 100% power-on time of the tool.

The concentration of substance is measured in the employee's respiratory zone.

 

 

SAWING 300 MM (WET) WITHOUT CONTROL MEASURES

Excess factor: 300 times limit respiratory quartz

SAWING 300 MM (WET) WITH CONTROL MEASURES

Prevention factor (PF): 35 – 300.
Concentration of quartz quartz at workplace below limit value (0.075 mg / m³).
