General Safety
Cumulative Trauma
Disorders ("CTD's")
CTD's, or musculoskeletal
disorders, involve damage
to the hands, wrists,
elbows, shoulders, neck,
and back. Carpal tunnel
syndrome and tendonitis
(such as tennis elbow or
rotator cuff syndrome) are
examples of CTD's.
The following hazards may occur during the normal use of this equipment.
Please read the following chart before using this equipment.
CAUSE
Solvent and coatings can be highly
flammable or combustible especially when
sprayed.
During use and while cleaning and flushing,
solvents can be forcefully expelled from
fluid and air passages. Some solvents can
cause eye injury.
Certain materials may be harmful if inhaled,
or if there is contact with the skin.
Halogenated hydrocarbon solvents - for
example; methylene chloride and 1,1,1,
- Trichloroethane are not chemically
compatible with the aluminum that might
be used in many system components. The
chemical reaction caused by these solvents
reacting with aluminum can become violent
and lead to an equipment explosion.
Improper operation or maintenance of
equipment.
Use of hand tools may cause cumulative
trauma disorders ("CTD's").
CTD's, when using hand tools, tend to affect
the upper extremities. Factors which may
increase the risk of developing a CTD include:
1. High frequency of the activity.
2. Excessive force, such as gripping,
pinching, or pressing with the hands and
fingers.
3. Extreme or awkward finger, wrist, or arm
positions.
4. Excessive duration of the activity.
5. Tool vibration.
6. Repeated pressure on a body part.
7. Working in cold temperatures.
CTD's can also be caused by such activities
as sewing, golf, tennis, and bowling, to
name a few.
SAFEGUARDS
Adequate exhaust must be provided to keep air free of
accumulations of flammable vapors.
Smoking must never be allowed in the spray area.
Fire extinguishing equipment must be present in the spray area.
Wear eye protection.
Follow the requirements of the Material Safety Data Sheet
supplied by your coating material manufacturer.
Adequate exhaust must be provided to keep the air free of
accumulations of toxic materials.
Use a mask or respirator whenever there is a chance of inhaling
sprayed materials. The mask must be compatible with the material
being sprayed and its concentration. Equipment must be as pre-
scribed by an industrial hygienist or safety expert, and be NIOSH
approved.
Guns with stainless steel internal passageways may be used
with these solvents. However, aluminum is widely used in other
spray application equipment - such as material pumps, regula-
tors, valves, and this gun and cup. Check all equipment items
before use and make sure they can also be used safely with these
solvents. Read the label or data sheet for the material you intend
to spray. If in doubt as to whether or not a coating or cleaning
material is compatible, contact your material supplier.
Operators should be given adequate training in the safe use
and maintenance of the equipment (in accordance with the
requirements of NFPA-33, Chapter 15). Users must comply with
all local and national codes of practice and insurance company
requirements governing ventilation, fire precautions, operation,
maintenance, and housekeeping. These are OSHA Sections
1910.94 and 1910.107 and NFPA-33.
Pain, tingling, or numbness in the shoulder, forearm, wrist,
hands, or fingers, especially during the night, may be early
symptoms of a CTD. Do not ignore them. Should you experience
any such symptoms, see a physician immediately. Other early
symptoms may include vague discomfort in the hand, loss of
manual dexterity, and nonspecific pain in the arm. Ignoring early
symptoms and continued repetitive use of the arm, wrist, and
hand can lead to serious disability. Risk is reduced by avoiding or
lessening factors 1-7.
