Hazards and Protection.
Storage
Keep containers tightly sealed. Keep away all sources of ignition. Take precautions against static discharges. Ensure all storage areas are well ventilated. Protect from heat. Store in a cool, dry area. Do not store or transport with acids, acid forming substances or oxidising substances. When stored correctly in tightly sealed containers, the product has a minimum shelf life of two years.
D2B E
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary.
Disposal code
5
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides (Roger Patrick, DuPont Engineer).
Decomposition
Nitrogen and carbon oxides.

Fire fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use dry chemical, dry sand, or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
May burn but does not ignite readily.
Hazards
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. May polymerize explosively when heated or involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Exposure effects
   Ingestion
Burns of the esophagus and less commonly the stomach may occur after caustic ingestion; the absence of oral mucosal injury does not reliably exclude esophageal burns. Patients with stridor, drooling or vomiting are more likely to have esophageal burns.
   Inhalation
Stridor, dyspnea, upper airway injury, and pulmonary edema, especially following inhalation of vaporized caustics, may occur.
   Skin
Severe skin irritation and/or burns may occur.
   Eyes
See Inhalation.

First aid
 
   Ingestion
Mucosal if no respiratory compromise is present, dilute immediately with milk or water; no more than 8 ounces in adults and 4 ounces in children. Gastric ipecac contraindicated. Consider insertion of a small, flexible nasogastric or orogastric tube to suction gastric contents after recent large ingestions; the risk of further mucosal injury must be weighed against potential benefits.
   Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
   Skin
Remove contaminated clothes. Irrigate exposed skin with copious amounts of water for at least 15 minutes or longer, depending on concentration, amount and duration of exposure to the chemical. A physician may need to examine the area if irritation or pain persist.
   Eyes
Home irrigation - exposed eyes should be irrigated with copious amounts of water for at least 30 minutes. An examination should always be performed. Ophthalmologic consultation should be obtained. Medical facility: irrigate with sterile 0.9% Saline for at least an hour or until the cul-de-sacs are free of particulate matter and returned to neutrality (confirm with pH paper).
