WARNING Dust and fume hazard
Dusts and/or fumes generated or dispersed when
using the machine may cause serious and
permanent respiratory disease, illness, or other
bodily injury (for example, silicosis or other
irreversible lung disease that can be fatal, cancer,
birth defects, and/or skin inflammation).
Some dusts and fumes created by drilling,
breaking, hammering, sawing, grinding and other
construction activities contain substances known to
the State of California and other authorities to
cause respiratory disease, cancer, birth defects, or
other reproductive harm. Some examples of such
substances are:
•
Crystalline silica, cement, and other masonry
products.
•
Arsenic and chromium from chemically-treated
rubber.
•
Lead from lead-based paints.
Dust and fumes in the air can be invisible to the
naked eye, so do not rely on eye sight to
determine if there is dust or fumes in the air.
To reduce the risk of exposure to dust and fumes,
do all of the following:
►
Perform site-specific risk assessment. The risk
assessment should include dust and fumes
created by the use of the machine and the
potential for disturbing existing dust.
►
Use proper engineering controls to minimize the
amount of dust and fumes in the air and to
minimize build-up on equipment, surfaces,
clothing, and body parts. Examples of controls
include: exhaust ventilation and dust collection
systems, water sprays, and wet drilling. Control
dusts and fumes at the source where possible.
Make sure that controls are properly installed,
maintained and correctly used.
►
Wear, maintain and correctly use respiratory
protection as instructed by your employer and
as required by occupational health and safety
regulations. The respiratory protection must be
effective for the type of substance at issue (and
if applicable, approved by relevant
governmental authority).
►
Work in a well ventilated area.
►
Since the machine has an exhaust, direct the
exhaust so as to reduce disturbance of dust in a
dust filled environment.
►
Operate and maintain the machine as
recommended in the operating and safety
instructions
►
Select, maintain and replace consumables/
working tools/ other accessories as
recommended in the operating and safety
instructions. Incorrect selection or lack of
maintenance of consumables/ inserted tools/
other accessories may cause an unnecessary
increase in dust or fumes.
►
Wear washable or disposable protective clothes
at the worksite, and shower and change into
clean clothes before leaving the worksite to
reduce exposure of dust and fumes to yourself,
other persons, cars, homes, and other areas.
►
Avoid eating, drinking, and using tobacco
products in areas where there is dust or fumes.
►
Wash your hands and face thoroughly as soon
as possible upon leaving the exposure area,
and always before eating, drinking, using
tobacco products, or making contact with other
persons.
►
Comply with all applicable laws and regulations,
including occupational health and safety
regulations.
►
Participate in air monitoring, medical
examination programs, and health and safety
training programs provided by your employer or
trade organizations and in accordance with
occupational health and safety regulations and
recommendations. Consult with physicians
experienced with relevant occupational
medicine.
►

body.
►
Adopt a comfortable posture while maintaining
secure footing and avoiding awkward offbalanced postures.
►
Changing posture during extended tasks may
help avoid discomfort and fatigue.
►
In case of persistent or recurring symptoms,
consult a qualified health professional.
WARNING Vibration hazards
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
nerves and blood supply or other body parts,
including debilitating and/or permanent injuries or
disorders that may develop gradually over periods
of weeks, months, or years. Such injuries or
disorders 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, persistent recurring discomfort,
burning sensation, stiffness, throbbing, 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, stop operating the machine, tell your
employer 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.
