( )
Signs & Symptoms of Exposure:
Ingestion: Irritation and/or burns can occur to the entire gastrointestinal tract, including the stomach and
intestines, characterized by nausea, vomiting, diarrhea, abdominal pain, bleeding and/or tissue ulceration.
Ingestion causes severe damage to the gastrointestinal tract with the potential to cause perforation.
Inhalation: Irritating to the nose, mouth, throat, and lungs. It may also cause burns to the respiratory tract with
the production of lung edema that can result in shortness of breath, wheezing, choking, chest pain, and
impairment of lung function. Inhalation of high concentrations can result in permanent lung damage from
the corrosive action of the lung.
Skin Contact: Dermal exposure can cause severe irritation and/or burns characterized by redness, swelling, and
scab formation. Prolonged skin exposure may cause permanent damage.
Eye Contact: Sever irritation and/or burns can occur following eye exposure. Contact may cause impairment of
vision and corneal damage.
Medical Conditions Aggravated by Exposure: Asthma, respiratory and cardiovascular disease.

UEL:
Auto-ignition Temperature: N/A
Extinguishing Media: Water. Do not use dry chemical extinguisher containing ammonia compounds.
Special Fire-fighting Procedures: Fire fighters should wear full protective clothing and self-contained breathing
apparatus (SCBA) in positive pressure mode. Cool containers with water spray. On small fires, use water
spray or fog. On large fires, use heavy deluge of fog streams. Flooding amounts of water may be required
before extinguishment can be accomplished.
Unusual Fire and Explosion Hazards: When heated to decomposition, may release poisonous and corrosive
fumes of nitrogen trichloride, chlorine, and carbon monoxide.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
Steps to Be Taken In Case Material Is Spilled or Released:
Hazardous concentrations in air may be found in local spill area and immediately downwind. If spill material is still
dry, do not put water directly on this product as a gas evolution may occur.
On Soil: Do not contaminate spill material with any organic materials, ammonia, ammonium salts, or urea.
Clean up all spill material with clean, dry dedicated equipment and place in a clean dry container.
On Water: This material is heavier than and soluble in water. Stop flow of material into water as soon a possible.
Begin monitoring for available chlorine and pH immediately.
In Air: vapors may be suppressed by the use of water fog.
SECTION 7 - HANDLING AND STORAGE
Precautions to Be Taken in Handling and Storage:
Handling: Do not take internally. Avoid contact with skin, eyes, and clothing. Upon contact with skin and eyes,
wash off with water.
Storage: Store in a dry, cool, well-ventilated area, away from incompatible materials. Do not store at
temperatures above 60°C/140°F. Product has an indefinite shelf-life limitation.
SECTION 8 - EXPOSURE CONTROLS/PERSONAL PROTECTION
Respiratory Protection: When dusty conditions are encountered, wear a NIOSH/OSHA full-face respirator with
chlorine cartridges, for protection against chlorine gas and dust/mist pre-filter. A respiratory protection
program meeting OSHA 1910.134 and ANSI Z88.2 requirements must be followed whenever workplace
conditions warrant a respirator's use.
Ventilation:
Local Exhaust: Use local exhaust ventilation to minimize dust and chlorine levels where industrial use occurs.
Otherwise, ensure good general ventilation.
Mechanical Exhaust:
Other Protective Clothing or Equipment: Neoprene gloves, Use chemical safety glasses to avoid eye contact.
Where industrial use occurs, chemical goggles may be required. Use impervious body covering clothes,
boots, and neoprene apron.
Work/ Hygienic Practices: Safety showers and eye bath should be provided. Do not eat, drink, or smoke until
after-work showering and changing clothes.
