generates dust that comes from the material
being processed, 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 disease (affecting your ability
to breathe), including chronic bronchitis,
silicosis and pulmonary fibrosis from
exposure to silica. These diseases may be
fatal;
Skin irritation and rash.
Cancer according to NTP* and IARC* */

Agency for Research on Cancer.
Take precautionary steps:

dust, mist and fumes.
Wear and ensure that all bystanders
wear appropriate respiratory protection such
as dust masks designed to filter out
microscopic particles. (See OSHA 29 CFR

To minimize dust emissions, use water
to bind the dust, when feasible. If dry
