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 disease (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.
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.
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 1926.1153)
To minimize dust emissions, wet cut when
feasible. If dry cutting is necessary, use an
appropriate dust extractor.
It is the owner's/employer's responsibility that the
operator has sufficient knowledge about how to use the
product safely. Supervisors and operators must have
read and understood the Operator's Manual. They must
be aware of:
