DUST WARNING

Cutting, especially when DRY cutting, generates dust that comes 
from the material being cut, which frequently contains silica. 

Silica is a basic component of sand, quartz, brick clay, granite and 
numerous other minerals and rocks. Exposure to excessive amount of 
such dust can cause:

• Respiratory diseases (affecting your ability to breath), including 

chronic bronchitis, silicosis and pulmonary fibrosis from exposure 

to silica. These diseases may be fatal;
• Skin irritation and rash; and
• Cancer according to NTP* and IARC*
* National Toxicology Program, International Agency for Research 
on Cancer

Take precautionary steps

• Avoid inhalation of and skin contact with dust, mist and fumes;
• Wet cut when feasible, to minimize dust;
• Wear and ensure that all bystanders wear appropriate respiratory 

protection such as dust masks designed to filter out microscopic 

particles. (See OSHA 29 CFR Part 1910.1200) 

California Prop 65 Warning: Use of this product can cause exposure to 
materials known to the State of California to cause cancer and/or birth 
defects or other reproductive harm.
