SECTION 4. FIRST AID
Eyes: Check for and remove any contact lenses. IMMEDIATELY flush eyes with running water for 15-30
minutes, keeping eyelids open. Use warm water if available. Seek medical attention.
Skin: MINOR CONTACT - Remove contaminated clothing as quickly as possible while protecting your own
hands and body. Place the person under a deluge shower. Gently and thoroughly wash the
contaminated skin with running water and non-abrasive soap. Use warm water if available. If irritation
persists, seek medical attention.
EXTENSIVE CONTACT 鈥? If skin surface is damaged, immediately flush skin with water while removing
contaminated clothing and shoes. Use warm water if available and continue flushing for at least 15, but
preferably 30, minutes. GET MEDICAL ATTENTION. Contaminated clothing should be discarded in a
manner that limits further exposure.
Inhalation: Using appropriate respiratory protection, remove the affected individual from the area of overexposure.
Loosen tight clothing. Allow the person to rest in a well-ventilated area. Give artificial respiration if
breathing has stopped. Obtain immediate medical attention.
Ingestion: Do not induce vomiting. Careful removal of the substance from the stomach by medical personnel is
required. Call a physician or poison control center immediately. Get immediate medical attention. If
tolerated, give no more than 1 cup of milk or water to rinse the mouth and throat and dilute the
stomach contents. No more than 8 ounces (1 cup) in adults and 4 ounces (陆 cup) in children is
recommended to minimize the risk of vomiting.

SECTION 5. FIRE AND EXPLOSION HAZARDS
Flash Point: Not applicable.
LEL/UEL Flammable Limits: Not applicable.
Autoignition Temperature: Not applicable.
Flammability Classification: Noncombustible.
Known Hazardous Products of Combustion: Can vigorously decompose under high temperature conditions
(>230掳F,>110掳C) to release carbon dioxide gas. Small
quantities of carbon dioxide will be released under normal
storage conditions. If material is exposed to prolonged heat in a
fire, oxides of carbon, nitrogen and sulfur may be formed.
Reactions that Release Flammable Gases or Vapors: May react with incompatible metals to generate highly
flammable and explosive hydrogen gas.
Unusual Fire & Explosion Hazards: Do not allow water to enter container because of violent
reaction. Container explosion may occur under fire conditions
or when heated. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Responders should consider the need for evacuation based on
concentrations of emitted decomposition products. Flammable
hydrogen gas may be produced on prolonged contact with
metals such as aluminum, tin, lead and zinc.
Extinguishing Media: Suitable for surrounding materials.
Special Firefighting Procedures: Wear positive pressure, self-contained breathing apparatus and
full turnout gear. Dike and collect water used to fight fire for
later treatment and disposal.
SECTION 6. SPILLS AND LEAKS
Evacuation: Warn personnel to move away. Isolate area. Keep unnecessary and unprotected personnel from
entering. Observe protective equipment requirements.
Containment: Stop leak if possible to do so without risk. Prevent product spillage from entering sewage or drainage
systems and drinking water supplies or streams.
Clean Up: Contain spill with dry earth or sand. Dilute 3 to 1 with water. Neutralize spill by slowly and carefully
applying powdered limestone or sodium carbonate to spill. Allow time to neutralize. Use appropriate
equipment to recover spilled material for disposal. Ensure disposal complies with government
requirements and local regulations. Consult your environmental advisor regarding recovery and
disposal alternatives.
Evacuation: Warn personnel to move away. Isolate area. Keep unnecessary and unprotected personnel from
entering. Observe protective equipment requirements.
SECTION 7. STORAGE AND HANDLING
Storage: Store in original container in a cool, well-ventilated, dry place at temperatures above
40oF. Do not store near food or feeds. Do not stack pallets more than 2 high.
Transfer Equipment: Will corrode incompatible metals. Polyethylene, polypropylene or 316L stainless steel
are acceptable materials of construction. Ensure that all pumps, valves, meters, gaskets,
etc. are of compatible material.
Work/Hygienic Practices: Personnel handling this material should be well trained in the use of personal protective
equipment, safe handling techniques, potential hazards and first aid requirements. Do
not breathe fumes or mists. Avoid contact with eyes and skin. Keep away from
incompatible materials. When using product, do not eat, drink or smoke. Ensure that an
eyewash station and safety shower is near place of use.

SECTION 8. PERSONAL PROTECTIVE EQUIPMENT
Eyes: Wear chemical safety goggles plus a face shield to prevent eye contact. As a general rule, do not
wear contact lenses when handling.
Skin: Wear acid resistant rubber gloves, boots, and a chemical resistant suit or apron.
Respiratory: In case of insufficient ventilation, wear suitable NIOSH/MSH approved respiratory equipment.
Protection provided by air purifying respirators may be limited.
Ventilation: Recommended but no exposure limit established by government authorities. The following
recommended occupational exposure limits are based on established ACGIH TLVs for acids: 8 hour
TWA = 1 mg/m3; 15 minute STEL = 3 mg/m3.

SECTION 10. STABILITY AND REACTIVITY
Stability: Stable.
Incompatibility: Reactive or incompatible with hypochlorites, sulfides, alkaline materials and many metals. Toxic
or flammable gases may be formed or unacceptable corrosion may result
Corrosivity: Extremely corrosive to copper, aluminum and zinc. Corrosive to mild steel, especially when
diluted. Slightly corrosive to 304 stainless steel. Non-corrosive to fiberglass, CPVC, polyethylene,
polypropylene or 316L stainless steel. Consult a metallurgical specialist to ensure compatibility
with handling equipment.

to prevent excessive heating or spatter. Avoid excessive heat. If heated above 110掳C will
decompose to produce carbon dioxide.
SECTION 11. POTENTIAL HEALTH EFFECTS
Acute Effects:
Eyes: Severe irritant. Contact may result in severe irritation or eye burns resulting in permanent damage.
Skin: Contact with intact skin does not normally cause immediate irritation, but prolonged contact may
result in redness, swelling, skin burns and severe damage. LD50=2000 mg/kg [rabbit].
Ingestion: Corrosive if swallowed. May cause severe irritation or burns to the mouth, throat and digestive tract.
LD50=350 mg/kg [rat].
Inhalation: Overexposure by inhalation may cause irritation and burning of the nose, throat and respiratory tract.
Chronic Effects: Prolonged or repeated overexposure by inhalation of skin or eye contact may result in severe
irritation or corrosive effects. MCDS is not known to be carcinogenic, mutagenic or teratogenic.

SECTION 12. ECOLOGICAL INFORMATION
May be harmful to fish, livestock and wildlife. Dissolved mineral salts may cause irritation of the digestive tract. Non-
persistent. Non-cumulative when applied using normal agricultural practices. The product itself and its products of
degradation (nitrogen oxides and sulfur oxides) are not harmful under normal conditions of careful and responsible
use.
Aquatic/Marine Toxicity: A toxic hazard to fish. Avoid spills or release to watercourses. Highly soluble. Will disperse
with current. Release to watercourses may cause effects down stream from the point of release. U.S. D.O.T.: This
material is not listed as a marine pollutant.
SECTION 13. DISPOSAL
Do not contaminate lakes, streams, ponds, estuaries, oceans or other waters by discharge of waste effluents or
equipment washwaters. Ensure disposal complies with government requirements and local regulations. Container
contents should be completely used and the containers rinsed prior to discard. Rinsate should be treated as a corrosive
material. Also, chemical additions or other alterations of this product may invalidate any disposal information in this
MSDS. Therefore, consult local waste regulators for proper disposal. Do not discharge.
