4. FIRST AID MEASURES
EYE CONTACT
Hold eyelids apart and immediately flush eyes with plenty of water for at least 15 minutes. Seek medical advice.
SKIN CONTACT
Remove contaminated clothing and shoes. Remove product and immediately flush affected area with water for at least 15
minutes. Cover the affected area with a sterile dressing or clean sheeting and transport for medical care. Do not apply greases
or ointments. Control shock, if present.
INHALATION
Move patient to fresh air. If breathing has stopped or is labored give assisted respiration (e.g. mouth-to-mouth). Supplemental
oxygen may be indicated. Seek medical advice. Turn victim's head to the side to prevent aspiration of vomit
INGESTION
If person is conscious and can swallow, immediately give two glasses of water, but do not induce vomiting. This material is
corrosive. If vomiting occurs, give fluids again. Have physician determine if condition of patient will permit induction of
vomiting or evacuation of stomach. Do not give anything by mouth to an unconscious or convulsing person.
Other Instructions
Swallowing of this corrosive material may result in severe ulceration, inflammation, and possible perforation of the upper
alimentary tract with hemorrhage and fluid loss. Aspiration of this product during induced emesis can result in severe lung
injury. If evacuation of stomach is necessary, use method least likely to cause aspiration, such as gastric lavage after
endotracheal intubation. Contact Poison Control Center for additional treatment information.

6. ACCIDENTAL RELEASE MEASURES
CONTAINMENT TECHNIQUES (Removal of ignition sources, diking etc)
Stop the leak, if possible. Ventilate the space involved. Shut off or remove all ignition sources. Construct a dike to prevent
spreading (includes molten liquids until they freeze).
CLEAN-UP PROCEDURES
If recovery is not feasible, admix with dry soil, sand or non-reactive absorbent and place in an appropriate
chemical waste container. Transfer to containers by suction, preparatory for later disposal. Place in metal
containers for recovery or disposal. Neutralize residue with dilute solution of Acetic Acid.. Flush area with water spray.
Clean-up personnel must be equipped with self-contained breathing apparatus and butyl rubber protective clothing.
OTHER EMERGENCY ADVICE
Open enclosed spaces to outside atmosphere. Wear protective clothing, boots, gloves, and eye protection. At
elevated temperatures a cartridge mask National Institute for Occupational Safety and Health (NIOSH) approved
for ammonia may be appropriate.
7. HANDLING AND STORAGE
STORAGE
Keep away from acids and oxidizers. Keep in cool, dry, ventilated storage areas and in closed containers. Do not store in
reactive metal containers.
HANDLING
Avoid contact with skin or eyes. Avoid breathing of vapors. Handle in well-ventilated workspace. When handling,
do not eat, drink, or smoke.
OTHER PRECAUTIONS
Emergency showers and eye wash stations should be readily accessible. Adhere to work practice rules established by
government regulations (e.g. OSHA). Do not use sodium nitrite or other nitrosating agents in formulations containing this
product. Cancer-causing nitrosamines could be formed.

EYE PROTECTION
Chemical Safety Glasses with Side-Shields. A full-face shield and vapor respirator is recommended for operations involving
spraying or other operations placing this material under pressurized conditions.
HAND PROTECTION
Neoprene rubber gloves. Impermeable gloves. Cuffed butyl rubber gloves. Nitrile rubber gloves. Polyvinyl chloride
gloves. Rubber Gloves. The breakthrough time of the selected glove(s) must be greater than the intended use
period. The selection of a specific glove for a particular application and duration of use in a workplace should also take into
account all requisite workplace factors such as, but not limited to: Other chemicals which may be handled, physical
requirements (cut/puncture protection, dexterity, thermal protection), as well as the instructions/specifications provided by the
glove supplier.
RESPIRATORY PROTECTION
An organic vapor respirator National Institute for Occupational Safety and Health (NIOSH) approved for organic vapors is
recommended where local ventilation is not adequate. At elevated temperatures, a cartridge mask National Institute for
Occupational Safety and Health (NIOSH) approved for ammonia may be appropriate.
PROTECTIVE CLOTHING
Chemical resistant apron, coveralls and other impervious clothing. A full-face shield and vapor respirator is recommended for
operations involving spraying or other broadcasting
ENGINEERING CONTROLS

Chemical Stability
Stable under normal handling and storage conditions, see Section 7,Handling and Storage.
Materials to Avoid
Mineral acids, Organic acids, Oxidizing Agents, Reactive metals, Sodium or Calcium
Hypochlorite. CAUTION! N-Nitrosamines, many of which are known to be potent carcinogens, may be formed when the
product comes in contact with nitrous acid, nitrites or atmospheres with high nitrous oxide concentrations. Product slowly
corrodes copper, aluminum, zinc and galvanized surfaces. Reaction with peroxides may result in violent decomposition of
peroxide possibly creating an explosion. Materials reactive with hydroxyl compounds. Nitrites, nitrosating agents. A reaction
accompanied by large heat release occurs when the product is mixed with acids. Heat generated may be sufficient to cause
vigorous boiling creating a hazard due to splashing or splattering of hot material.
HAZARDOUS DECOMPOSITION PRODUCTS (from burning, heating, or reaction with
other materials).
Nitrogen oxide can react with water vapors to form corrosive nitric acid (TLV=2 ppm). Carbon Monoxide in a fire.
Carbon Dioxide in a fire. Ammonia when heated. Nitrogen Oxides in a fire. Irritating and toxic fumes at elevated
Temperatures. Nitric acid in a fire. Nitrosamines. The oxides of nitrogen gases (except nitrous oxide) emitted on
decomposition are highly toxic.
