Hazards and Protection.
Aqueous solutions are stable for periods over 2 weeks in alkaline or neutral pH and room temperature. Acid solutions are slightly less stable. Store at in dark bottles since dibutylnitrosamine is light sensitive.
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.
Dispensers of liquid detergent should be available. Protective suits (preferably disposable, one-piece and close-fitting at ankles and wrists), gloves, hair covering and overshoes. In the laboratory, gloves and protective clothing should always be worn but should not be assumed to provide full protection. Carefully fitted masks or respirators when working with particulates or gases. Protective clothing should be a distinctive color.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Stable @ room temperature for more than 14 days in neutral or alkaline aqueous solution in dark, slightly less stable in acidic solution; light-sensitive, esp to UV light.
Strong oxidizing agents.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

The toxicological properties of this material have not been investigated.
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
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.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Pesticides - remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing. Irritation - treat dermal irritation or burns with standard topical therapy
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
