Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)
Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 mg/kg up to 200 mL of water for dilution if the patent can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Cover skin bums with dry sterile dressings after decontamination . /Organic bases/Amines and related compounds/
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.
Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Those substances designated with a (P) 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. (ERG, 2016)
Use water spray, dry powder, foam.

NIOSH considers beta-naphthylamine to be a potential occupational carcinogen.
Decomposes on burning. This produces toxic and corrosive fumes including nitrogen oxides.
Stable in cold in absence of air; oxidizes in presence of air; volatile in steam
It is combustible and at elevated temperatures evolves a vapor which is flammable ... Fire hazard: moderate, when exposed to heat or flame.Dust explosion possible if in powder or granular form, mixed with air.BETA-NAPHTHYLAMINE is a weak base.

The substance may be irritating to the respiratory tract and skin. The substance may cause effects on the blood. This may result in the formation of methaemoglobin. The substance may cause effects on the bladder. This may result in inflammation and blood in the urine. Medical observation is indicated. The effects may be delayed. See Notes.
This substance is carcinogenic to humans. See Notes.
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
AEROBIC: In a test for primary biodegradation, 2-naphthylamine was not degraded in chernozem soil after 90 days at an initial concentration of 500 mg/kg(1). The maximum mineralization rate for 2-naphthylamine (conc. 50 ug/g) in a soil/water suspension over 220 days was 0.12 ug/g-day during a short initial phase and 0.027 ug/g-day during a longer second phase(2). Addition of fresh amounts of 2-naphthylamine (conc. 50 ug/g) at 220 days restored the mineralization to the initial phase rate value. The recalcitrance of aminonaphthalenes in soil has been attributed to their ability to form complexes with soil matter which, to a large extent, renders them biologically unavailable(3).
An estimated BCF of 11 was calculated for 2-naphthylamine(SRC), using a log Kow of 2.28(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).
The measured Koc for 2-naphthylamine is 1,000(1). According to a classification scheme(2), this Koc value suggests that 2-naphthylamine is expected to have low mobility in soil. Results of a batch equilibrium study with various soils indicated that 1-naphthylamine, which is structurally analogous to 2-naphthylamine, binds to soil in two phases with an initial rapid and reversible equilibrium established between the amine and the inorganic and organic components of soil followed subsequently by a strong association with the humic fraction of soil via covalent binding(3,4). Aminonaphthalenes are known to form complexes with soil matter(5). The pKa of 2-naphthylamine is 4.16(6), indicating that this compound will partially exist in cation form in the environment.

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.
