Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .
Moderately toxic: probable oral lethal dose (human) 0.5-5 gm/kg, or between 1 ounce and 1 pint (or l lb.) for 150 lb. person. Chronic sublethal exposure may cause antithyroid activity. Can produce hyperglycemia of three times normal in three hours. People with chronic respiratory disease or liver disease may be especially at risk. (EPA, 1998)
Treatment includes gastrointestinal decontamination with activated charcoal, supportive care, and monitoring of electrolytes and glucose. Pulmonary edema may be delayed up to 72 hours. Patients ingesting more than 5 mg/kg body weight should be admitted for observation.
If material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire (Material itself does not burn or burns with difficulty). Use water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources. Naphthylthiourea
Emits sulfur dioxide, oxides of nitrogen, and carbon monoxide fumes upon decomposition. It reacts with silver nitrate and strong oxidizers. Avoid decomposing heat. (EPA, 1998)
Use water spray, powder, foam, carbon dioxide.
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Ventilate area of spill. For small quantities, sweep onto paper or other suitable material, place in appropriate container and burn in safe place (such as fume hood). Large quantities may be reclaimed ... If not practical, dissolve in flammable solvent ... and atomize in ... combustion chamber ...
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Decomposes on heating. This produces toxic gases and toxic fumes including nitrogen oxides, sulfur oxides and carbon monoxide. Reacts with strong oxidants such as silver nitrate. This generates fire and explosion hazard.
Stable on exposure to air and to sunlight.
To fight fire use:/Powder, water spray, foam, carbon dioxide.ANTU is incompatible with the following: Strong oxidizers, silver nitrate (NIOSH, 2016).

Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

An estimated BCF of 5.7 was calculated in fish for alpha-naphthylthiourea(SRC), using a log Kow of 1.65(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Using a structure estimation method based on molecular connectivity indices(1), the Koc of alpha-naphthylthiourea can be estimated to be 3600(SRC). According to a classification scheme(2), this estimated Koc value suggests that alpha-naphthylthiourea is expected to have slight mobility in soil. The pKa of alpha-naphthylthiourea is estimated as 9.47(3), indicating that this compound will exist partially in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
