First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth.
Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound may include irritation. ACUTE/CHRONIC HAZARDS: This compound may be harmful by ingestion and inhalation. It may cause irritation. When heated to decomposition it emits toxic fumes of carbon monoxide, carbon dioxide and nitrogen oxides. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
In an/ ... experiment conducted with groups of 2 to 3 rats, each rat was treated with 200 uL of 50 % hair colorant base containing 0.025 to 0.48 % /2-nitro-p-phenylenediamine/ (2NPPD) (14C) on 10 sq cm of skin for five minutes. The base was rinsed off, and a 48-hour nonocclusive patch was applied. Skin penetration increased with increasing 2NPPD concentration and was proportional to 2NPPD concentration; it was 0.01 ug/sq cm with 0.025 % 2NPPD and 3.2% with 0.48 % 2NPPD.

Persistence and degradability
AEROBIC: Information is not available regarding the biodegradation potential of 2-nitro-p-phenylenediamine; however, 80% percent of p-phenylenediamine was removed over 120 hours based on chemical oxygen demand measurements and using an activated sludge inoculum(1).
Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for 2-nitro-p-phenylenediamine(SRC), using a log Kow of 0.53(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).
Mobility in soil
The Koc of 2-nitro-p-phenylenediamine is estimated as 46(SRC), using a log Kow of 0.53(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-nitro-p-phenylenediamine is expected to have very high mobility in soil. However, anilines (aromatic amines) are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4), suggesting that mobility may be much lower in some soils(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
