Noise hazard
Warning
High sound levels may cause permanent hearing
loss.
Use hearing protection in accordance with
occupational health and safety regulations.
Silica/Dust hazard
Warning
Exposure to crystalline silica (sometimes called
‘silica dust’) as a result of breaking, hammering, or
other activities involving rock, concrete, asphalt or
other materials may cause silicosis (a serious lung
disease), silicosis-related illnesses, cancer, or death.
Silica is a major component of rock, sand and
mineral ores.
To reduce silica exposure:
Use proper engineering controls to reduce the
amount of silica in the air and the build-up of
dust on equipment and surfaces. Examples
of such controls include: exhaust ventilation,
dust collection systems and water sprays. Make
sure that controls are properly installed and
maintained.
Wear, maintain, and correctly use approved
particulate respirators when engineering
controls alone are not adequate to reduce
exposure below permissible levels.
Participate in air monitoring, medical exams,
and training programs offered by your employer
and when required by law.
Wear washable or disposable protective clothes
at the worksite; shower and change into clean
clothes before leaving the worksite to reduce
exposure of silica to yourself, other persons,
cars, homes, and other areas.
Do not eat, drink, or use tobacco products in
areas where there is dust containing crystalline
silica.
Wash your hands and face before eating,
drinking, or using tobacco products outside of
the exposure area.
Work with your employer to reduce silica
exposure at your worksite.
Warning
Some dust, fumes or other airborne material
created during use of the machine may contain
chemicals known to the State of California to cause
cancer and birth defects or other reproductive
harm. Some examples of such chemicals are:
Crystalline silica and cement and other masonry
products.
Arsenic and chromium from chemically-treated
rubber.
Lead from lead based paints.
To reduce your exposure to these chemicals,
work in a well ventilated area, and work with
approved safety equipment, such as dust masks
that are specially designed to filter out microscopic
particles.
Vibration hazard
Warning
Normal and proper use of the machine exposes
the operator to vibration. Regular and frequent
exposure to vibration may cause, contribute to,
or aggravate injury or disorders to the operator’s
fingers, hands, wrists, arms, shoulders and/or
other body parts, including debilitating and/or
permanent injuries or disorders that may develop
gradually over periods of weeks, months, or years.
Such injury or disorder may include damage to the
blood circulatory system, damage to the nervous
system, damage to joints, and possibly damage to
other body structures.
If numbness, tingling, pain, clumsiness, weakened
grip, whitening of the skin, or other symptoms
occur at any time, when operating the machine
or when not operating the machine, do not
resume operating the machine and seek medical
attention. Continued use of the machine after the
occurrence of any such symptom may increase the
risk of symptoms becoming more severe and/or
permanent.
The following may help to reduce exposure to
vibration for the operator:
Let the tool do the job. Use a minimum hand
grip consistent with proper control and safe
operation.
