Remove contaminated clothes. Rinse and then wash skin with water and soap.
Rinse with plenty of water (remove contact lenses if easily possible).
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Exposure Routes: inhalation, skin absorption, ingestion, skin and/or eye contact Symptoms: Headache, dizziness; cyanosis; red blood cell Heinz bodies Target Organs: Blood, kidneys, liver, cardiovascular system, central nervous system (NIOSH, 2016)
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. Aniline and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
Use dry chemical, carbon dioxide, or alcohol foam extinguishers. Vapors are heavier than air and will collect in low areas. Vapors may travel long distances to ignition sources and flashback. Vapors in confined areas may explode when exposed to fire. Storage containers and parts of containers may rocket great distances, in many directions. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position ... The only respirators recommended for fire fighting are self-contained breathing apparatuses that have full facepieces and are operated in a pressure-demand or other positive-pressure mode. Anisidines
Specific hazards arising from the chemical
This chemical is flammable. (NTP, 1992)
Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
Spill handling: Evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area after clean-up is complete. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. It may be necessary to contain and dispose of this chemical as a hazardous waste. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. Anisidines
SECTION 7: Handling and storage
Precautions for safe handling
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.
Conditions for safe storage, including any incompatibilities
Separated from strong oxidants, strong bases, acids, chloroformates and food and feedstuffs. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.Store in tightly closed containers in a cool, dark, well-ventilated area. Protect against sunlight and strong oxidizers. Metal containers involving the transfer of this chemical should be grounded and bonded. Where possible, automatically pump liquid from drums or other storage containers to process containers. Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only non-sparking tools and equipment, especially when opening and closing containers of this chemical. Sources of ignition, such as smoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could create a potential fire or explosion hazard. A regulated, marked area should be established where this chemical is handled, used, or stored ... Anisidines

Persistence and degradability
AEROBIC: p-Anisidine, present at 100 mg/L, reached 65.3% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). p-Anisidine degraded 82% in river water obtained from Mino River, Japan, and 2% in seawater obtained from Akashi Beach, Japan during a Cultivation Method screening test(2). p-Anisidine did not degrade during a Modified OECD test, but degraded completely after 28 days using the same procedure with a modified activated sludge (1.5 mL/L) inoculum and a test sample concn of 60 mg/L(3). Half-lives of <3 weeks in non-adapted inoculum and <2 weeks in adapted inoculum were obtained during an adapted, semistatic OECD biogradability test and dynamic Pitter test(4). p-Anisidine, present at 25 ug/L and inoculated with a mixed culture of soil microorganisms in an aqueous mineral salts medium, underwent complete degradation in 64 days as indicated by a total loss of UV absorbency(5). Partially purified enzymes of the soil fungus Geotrichum candidum transformed the anisidines into colored polyaromatic hydrocarbons(6). Pure cultures of the bacterium Escherichia coli metabolized p-anisidine in the presence of nitrate, as indicated by a color change occurring within 24 hours of incubation; a disappearance rate of 0.10/hr was reported(7).
Bioaccumulative potential
An estimated BCF of 3.2 was calculated for p-anisidine(SRC), using a log Kow of 0.95(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 p-anisidine is estimated as 45(SRC), using a log Kow of 0.95(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that p-anisidine is expected to have very high mobility in soil. The pKa of p-anisidine is 5.36(4), indicating that this compound will partially exist in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
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.
