FIRE AND EXPLOSION
Flash Point (TCC): NE
Explodibility Limits in Air for Chlorine Dioxide (% by volume):
Upper (UEL) = NE
Lower (LEL) = 10%
UNUSUAL FIRE, EXPLOSION AND REACTIVITY HAZARDS
Product is an oxidizer. Oxidizers decompose, especially when heated, to yield oxygen or other gasses
which will increase the burning rate of combustible matter. Contact with moisture will produce
Chlorine Dioxide gas. The lower explosive limit (LEL) for chlorine dioxide is 10%. If large amounts
of the product are involved in a fire, it is possible that the application of water mist or fog could
release enough chlorine dioxide gas in a confined space to present an explosion hazard. The chlorine dioxide will dissolve harmlessly in flooding amounts of water.
IN CASE OF FIRE
Extinguisher Media: Flooding amounts of water.
Special Fire Fighting Procedures: Positive pressure, self-contained breathing apparatus. Wear
full protective clothing. Apply water from a protected location or from a safe distance.
SECTION 6. ACCIDENTAL RELEASE MEASURES
PEL/TLV Note: Upon exposure to moisture, this product releases chlorine dioxide. The OSHA PEL, as
well as the ACGIH TLV, for chlorine dioxide is 0.1 ppm, 0.3 ppm STEL.
SECTION 3. HAZARDS IDENTIFICATION
MOST IMPORTANT HAZARDS
Irritating to eyes, respiratory system and skin, harmful if swallowed. May cause burns. May cause pain,
nausea, vomiting and diarrhea. Danger: Oxidizer. Contact with combustible material may cause fire.
NOTES TO PHYSICIAN
Probable mucosal damage may contraindicate the use of gastric lavage.
SIGNS/SYMPTOMS OF EXPOSURE
Inhalation: Harmful if inhaled. Exposure to dust particles generated from this material causes irritation of the respiratory tract. May result in burns of the mucous membranes, bronchospasms,
coughing, delayed pulmonary edema, difficulty breathing and sore throat.
Ingestion: Harmful if swallowed. May cause irritation to the mouth, throat and stomach. May cause
pain, nausea, vomiting and diarrhea. May cause weakness and fatigue.
Skin Contact: Harmful by skin contact. Contact with moist skin may cause burns. May cause toxic
effects by prolonged or extensive skin contact. Causes skin irritation. Prolonged contact may cause dermatitis. Contact with a 500 ppm of this product, was slightly irritating to rabbit skin. (See section 11.)
Eye Contact: Causes severe eye irritation. May cause eye burns. Causes eye damage.
Other Effects: Note: Upon exposure to moisture, this product releases Chlorine Dioxide gas.
Inhalation of Chlorine Dioxide may cause irritation, coughing, wheezing and burning of the mucous
membranes. Inhalation of large amounts may lead to pulmonary edema and bronchitis. Direct contact
with Chlorine Dioxide causes eye and skin irritation and may cause burns. Toxic by oral exposure.
ROUTES OF ENTRY
Primary: Inhalation
Secondary: Skin/Eye
Tertiary: Ingestion
HAZARDOUS DECOMPOSITION PRODUCTS
Chlorine. This product can decompose exothermically, releasing a large amount of heat.
UNUSUAL FIRE, EXPLOSION AND REACTIVITY HAZARDS
Product is an oxidizer. Oxidizers decompose, especially when heated, to yield oxygen or other gasses
which will increase the burning rate of combustible matter. Contact with moisture will produce
Chlorine Dioxide gas. The lower explosive limit (LEL) for chlorine dioxide is 10%. If large amounts
of the product are involved in a fire, it is possible that the application of water mist or fog could
release enough chlorine dioxide gas in a confined space to present an explosion hazard. The chlorine dioxide will dissolve harmlessly in flooding amounts of water.
SECTION 4. FIRST AID MEASURES
Have the product container or label with you when calling a poison control center or doctor or going for
treatment. Describe any symptoms and follow the advice given.
Eye Contact: Hold eyes open and rinse slowly and gently with water for 15 - 20 min. Remove contact lenses, if present, after the first 5 min, then continue rinsing eyes. Call a poison control center
or doctor for 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 to do so by the poison control center or doctor. Do not give anything by mouth to an unconscious person.
IN CASE OF SPILL OR LEAK
Contain spillage. Scoop up or vacuum into a container for reclamation or disposal. Avoid dusting. If
a solution of this product is spilled, take up as much a possible and place in a suitable container for
disposal in compliance with local regulations. Dilute chlorine dioxide solutions (100 - 200 ppm) do
not need to be pH neutralized. Flush residual material, down drain, with an excess of water, in accordance with local regulations.
This product contains no Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA) listed chemicals. Releases of this product are NOT reportable to the National Response Center.

burns. May be fatal if absorbed through skin. Harmful if swallowed. Do not get in eyes, on skin or on
clothing. Wear protective eyewear (goggles, face shield or safety glasses), protective clothing and
rubber gloves. Wash thoroughly with soap and water after handling and before eating, drinking or
using tobacco. Remove contaminated clothing and wash clothing before reuse.

Respiratory Protection: None required when exposure limits are not likely to be exceeded. Refer to
the label and Section 2 of this MSDS. If overexposure is likely or if used in enclosed or confined areas,
a NIOSH approved respirator with an organic vapor (OV) cartridge or canister with any R or P prefilter
may be used. See 29 CFR 1910.134 for respiratory protection, training and testing requirements.
Protective Gloves: Wear chemical-resistant rubber gloves. (Good practice requires that gross amounts
of any chemical be removed from the skin as soon as practical, especially before eating or smoking.)
