Aggravated by Exposure as asthma, emphysema or bronchitis. Skin contact may aggravate existing skin
disease.
SECTION 4. FIRST AID MEASURES
Eye Hold eye open and rinse slowly and gently with water for 15-20 minutes.
Remove contact lense, if present, after the first 5 miutes, then continue rinsing
eye. Call a poison control center or doctor for treatment advice.
Skin Take off contaminated clothing. Rinse skin immediately with plenty of water for
15-20 minutes. Call a poison control center or doctor for further treatment advice.
Ingestion Call a poison control center or doctor immediately for treatment advice. Have
person sip a glass of water if able to swallow. Do not induce vomiting unless told
by a poison control center or doctor. Do not give anything by mouth to an
unconscious person.
Inhalation Move person to fresh air. If person is not breathing, call 911 or ambulance, and
then give artificial respiration preferably mouth-to-mouth if possible. Call poison
control center or doctor for further treatment advice.
Note to Physician All treatments should be based on observed signs and symptoms of distress in
the patient. Consideration should be given to the possibility that overexposure to
materials other than this product may have occurred.
Probable mucosal damage may contraindicte the use of gastric lavage. No
specific antidote is available. All treatments should be based on observed signs
and symptoms of distress in the patient.
Victims of severe overexposure, by inhalation, should be kept under medical
observation for up to 72 hours for delayed onset of pulmonary edema. In a
victim of overexposure by ingestion, careful gastric lavage is required due to the
possibility of stomach or esophageal perforation. This material is an acid, but
the use of alkaline substances to neuttralize it is contraindicted.

SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls Where engineering controls are indicated by use conditions or a potential for
excessive exposure exists, the following traditional exposure control techniques
may be used to effectively minimize employee exposures.
Eye/Face Protection Eye and face protection requirements will vary dependent upon work
environment conditions and material handling practices. Appropriate ANSI Z87
approved equipment should be selected for the particular use intended for this
material.
Face contact should be prevented through use of a face shield and protective
eyewear.
Body Protection Skin contact must be prevented through the use of permeation resistant clothing
including long-sleeved shirts and long pants, chemical resistant gloves and
shoes plus socks, selected with regard for use conditions and exposure
potential.
An emergency shower must be readily accessible to the work area.
Consideration must be given both to durability as well as permeation resistance.
Respiratory Protection When respirators are required, select NIOSH/MSHA approved equipment based
on actual or potential airborne concentrations and in accordance with the
appropriate regulatory standards and/or industrial recommendations.
Under normal conditions, in the absence of other airborne contaminants,the
following devices should provide protection from this material up to the
conditions specified by the appropriate OSHA, WHMIS or ANSI standard(s): Air-
purifying (half-mask/full-face) respirator with cartridges/canister approved for use

against dusts, mists and fumes, pesticides.
Under conditions immediately dangerous to life or health, or emergency
conditions with unknown concentrations, use a full-face positive pressure air-
supplied respirator equipped with an emergency escape airsupply unit or use a
self-contained breathing apparatus unit.
General Protection These recommendations provide general guidance for handling this product.
Because specific work environments and material handling practices vary, safety
procedures should be developed for each intended application. While developing
safe handling procedures, do not overlook the need to clean equipment and
piping systems for maintenance and repairs. Waste resulting from these
procedures should be handled inaccordance with Section 13: Disposal
Considerations.
Assistance with selection, use and maintenance of worker protection equipment
is generally available from equipment manufacturers.
