SECTION 3 鈥? HAZARD IDENTIFICATION
Emergency Overview: Pale green, clear, non-volatile liquid. CORROSIVE! Can
cause severe irritation to eyes and skin. Highly reactive to strong acids, reducing
substances producing toxic and potentially explosive amounts of chlorine dioxide
gas. Combustible materials saturated with dried solution and exposed to heat can
ignite. Toxic to aquatic organisms. Read the entire MSDS for a more thorough
evaluation of the hazards.
Potential Health Effects:
Inhalation: Does not readily form a vapor and inhalation exposure is likely to occur
as an aerosol. Due to its corrosive nature, aerosols could cause pulmonary edema
(severe, life-threatening lung injury). The development of pulmonary edema may be
delayed up to 48 hours after exposure. The early symptoms of pulmonary edema
include shortness of breath and tightness in the chest.
Skin Contact: Corrosive! Capable of causing severe irritation and/or burns with
symptoms of redness, itching, swelling, and possible destruction of tissue. The
severity of injury depends on the concentration (solutions) and the duration of
exposure.
Eye Contact: Corrosive! The severity of injury increases with the concentration,
the duration of exposure, and the speed of penetration into the eye. Damage can
range from severe irritation and mild scarring to blistering, disintegration, ulceration,
severe scarring and clouding.
Ingestion: May cause gastroenteritis with any or all of the following symptoms:
nausea, pain, burning of the mouth, throat and esophagus; vomiting; diarrhea;
collapse, bleeding or ulceration. Acute ingestion of large quantities may also cause
anemia due to the oxidizing effects of the chemical.
Chronic Effects: Repeated or prolonged skin contact would be expected to cause
drying, cracking, and inflammation of the skin (dermatitis).
Existing Medical Conditions Possibly Aggravated By Exposure : Asthma,
bronchitis, emphysema and other lung diseases and chronic nose, sinus or throat
conditions. Skin irritation may be aggravated in individuals with existing skin
disorders.
Carcinogenicity: Not classified as a carcinogen by ACGIH (American Conference of
Governmental Industrial Hygienists) or IARC (International Agency for Research on
Cancer), not regulated as a carcinogen by OSHA (Occupational Safety and Health
Administration), and not listed as a carcinogen by NTP (National Toxicology
Program).

SECTION 4 鈥? FIRST AID MEASURES
General: If you feel unwell seek medical advice (show the label where possible).
Inhalation: Move victim to fresh air. If breathing is difficult, oxygen may be
beneficial if administered by trained personnel, preferably on a doctor's advice. Give
artificial respiration ONLY if breathing has stopped. Do not use mouth-to-mouth
method if victim ingested or inhaled the substance: induce artificial respiration with
the aid of a pocket mask equipped with a one-way valve or other proper respiratory
medical device. Give Cardiopulmonary Resuscitation (CPR) only if there is no pulse
AND no breathing. Obtain medical attention IMMEDIATELY. Symptoms of
pulmonary edema can be delayed up to 48 hours after exposure.
Skin Contact: Immediately flush skin with running water for at least 20 minutes and
upward to 60 minutes is recommended. Under running water remove contaminated
clothing, jewelry, and shoes. If irritation persists, repeat flushing. For burns, obtain
medical attention. Discard contaminated clothing and shoes in a manner, which
limits further exposure.
Eye Contact: Immediately flush eyes with running water for a minimum of 20 minutes
and upward to 60 minutes is recommended. Hold eyelids open during flushing. If
irritation persists, repeat flushing. Obtain medical attention IMMEDIATELY. Do not
transport victim until the recommended flushing period is completed unless flushing
can be continued during transport.
Ingestion: DO NOT INDUCE VOMITING. If victim is alert and not convulsing,
rinse mouth and give as much water as possible to dilute material (8 to 10 oz.). If
spontaneous vomiting occurs, have victim lean forward with head down to avoid
breathing in of vomitus, rinse mouth and administer more water. IMMEDIATELY
transport victim to an emergency facility.

Fire and Explosion Hazards: Does not burn, but combustibles wetted with this
solution and subsequently allowed to dry are easily ignited and will burn vigorously
Extinguishing Media: Water is the only effective extinguisher in the event of a fire
with combustibles.
Special Information: Evacuate area and fight fire from a safe distance or a
protected location, especially in the event that the solution is in contact with acids,
which can generate toxic amounts of chlorine dioxide gas. Approach fire from
upwind. If possible, isolate materials not involved in the fire and protect personnel.
Move containers from fire area if it can be done without risk. Water should be used
to extinguish the fire.
Fire Fighting Protective Equipment: Firefighter's normal protective clothing
(Bunker Gear) will not provide adequate protection. Chemical resistant clothing (e.g.
chemical splash suit) and positive pressure self-contained breathing apparatus
(MSHA/NIOSH approved or equivalent) may be necessary.
NOTE: Also see "Section 10 - Stability and Reactivity"
SECTION 6 鈥? ACCIDENTAL RELEASE MEASURES
Spills, Leaks, or Releases:
鈥? Restrict access to area until completion of clean up. Ensure that trained
personnel conduct the clean up. Ventilate area.
鈥? Wear adequate personal protective equipment (See Section 8). Do not touch
spilled material.
鈥? Prevent entry into sewers or waterways.
鈥? Land spills of solution should be contained by diking with an inert material, such
as sand or earth, and not with any combustible materials such as sawdust. The
material should be made alkaline with the addition of sodium carbonate (soda
ash) to prevent any generation of chlorine dioxide. The material should then be
collected into clean metal or high density polyethylene containers.
鈥? Water spill: Make alkaline with soda ash.
鈥? Comply with Federal, Provincial/State and local regulations on reporting
releases.
Deactivating Chemicals: Dilute solution or material with water, add soda ash to
make solution alkaline followed by the addition of dilute aqueous sodium sulfite.
Waste Disposal Methods: Dispose of waste material at an approved waste
treatment/disposal facility, in accordance with applicable regulations. Do not dispose
of waste with normal garbage or to sewer systems because it is an oxidizer.

SECTION 7 鈥? HANDLING AND STORAGE
Precautions: Have emergency equipment (for fires, spills, leaks, etc.) readily
available. Ensure all containers are labeled. Wear appropriate Personal Protection
Equipment. Product is NOT compatible with acids and combustibles such as cloth,
leather, and paper. People working with this chemical should be properly trained
regarding its hazards and its safe use.
Handling Procedures and Equipment: Use smallest possible amounts in
designated areas with adequate ventilation. Keep containers closed when not in
use. Empty containers may contain hazardous residues and should be properly
rinsed or washed to remove residues. Avoid generating mists. Transfer solutions
using equipment, which are corrosion-resistant. Cautiously, transfer into sturdy
containers made of compatible materials. Never return contaminated material to its
original container.
Storage Requirements: Store in a cool, dry, fireproof, well-ventilated area. Keep
containers tightly closed when not in use and when empty. Protect from damage.
Store away from incompatible materials such as strong acids, reducing agents, and
combustibles. See Section 10 for Incompatibles. Use corrosion-resistant structural
materials and lighting and ventilation systems in the storage area. Containers made
of plastics or plastic-lined steel, or FRP tanks of Derakane vinyl ester resin may be
suitable. Container contents may develop pressure after prolonged storage. Drums
may need to be vented. Trained personnel should only perform venting.
Storage Temperature: Avoid freezing. Do not expose sealed containers to
temperatures above 50 潞C (122 潞F).
SECTION 8 鈥? EXPOSURE CONTROLS / PERSONAL PROTECTION
PREVENTIVE MEASURES
Recommendations listed in this section indicate the type of equipment, which
will provide protection against over exposure to this product. Conditions of
use, adequacy of engineering or other control measures, and actual
exposures will dictate the need for specific protective devices at your
workplace.
Engineering Controls: Use separate, corrosion resistant local exhaust ventilation
wherever there is an incidence of point source emissions or dispersion of regulated
contaminants in the work area. Ventilation control of the contaminant as close to its
point of generation is both the most economical and safest method to minimize
personnel exposure to airborne contaminants. Do not use wood or other
combustibles to construct the system. Prevent entry of solution into motor bearings
or gear boxes, which could cause an explosion by reaction with petroleum
lubricants.
