Fresh air, rest.
Rinse and then wash skin with water and soap.
Rinse with plenty of water (remove contact lenses if easily possible).
Rinse mouth.
Most important symptoms/effects, acute and delayed
Ingestion causes gastrointestinal disturbances. Contact causes eye irritation and, if prolonged, irritation of skin. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Ketones and related compounds

SECTION 10: Stability and reactivity
Reactivity
On combustion, forms toxic gases. Reacts with strong oxidants. This generates fire and explosion hazard.
Decomposes on burning. This produces toxic fumes.
Chemical stability
no data available
Possibility of hazardous reactions
CombustibleKetones, such as BENZOPHENONE, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. This compound can react with oxidizing materials. (NTP, 1992)
Conditions to avoid
no data available
Incompatible materials
Dust can form explosive mixture with air.
Hazardous decomposition products
When heated to decomp it emits acrid and irritating fumes.

Aspiration hazard
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed.
SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Pimephales promelas - 15.3 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 6.784 mg/L - 48 h.
- Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 3.5 mg/L - 72 h.
- Toxicity to microorganisms: EC50 - activated sludge of a predominantly domestic sewage - 787 mg/L - 3 h. Remarks:Respiration rate.
Persistence and degradability
AEROBIC: Benzophenone, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). In a separate screening test, benzophenone reached 12% of its theoretical BOD over an incubation period of 5 days using a sewage sludge inoculum(2). The removal of benzophenone from soil columns treated with feed solutions containing 5.8X10-5, 1.3X10-4, 1.1X10-4, and 2X10-3 ppm benzophenone was 15, 41, 45, and 40%, respectively(3). An increase in the column effluent concentration of benzophenone after mercuric chloride was added to the feed solution indicated that some biodegradation took place in the soil column(3).
Bioaccumulative potential
BCF values of 3.4-9.2 were measured using carp (Cyprinus carpio) which were exposed to benzophenone concentrations of 0.3 ppm over an 6-week period(1). According to a classification scheme(2), this BCF range suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Kd for benzophenone was measured to be 2.71 on a red earth soil from Australia with an organic matter content of 1.09%(1), corresponding to a Koc of about 430(SRC). The average Koc value from three soils was measured to be 517(2). According to a classification scheme(3), these Koc values suggest that benzophenone is expected to have moderate to low mobility in soil. Benzophenone was detected (concentration below 0.500 ug/L) in both the treated effluent applied at the top of a 2.4 m long, 32.5 cm diameter soil column and in the drainage collected from the bottom of the column after 23 days(4).
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.
