Most important symptoms/effects, acute and delayed
Dust may cause swelling of eyes and eye injury, irritation of nose and throat. Solid irritates skin on prolonged contact. (USCG, 1999)
SYMPTOMS: Symptoms of exposure to this type of compound include irritation of the nose and pharynx. It can produce redness, edema and chemical burns on skin contact. In the eyes it induces conjunctival irritation, corneal injury and iritis. Symptoms of exposure to a related compound may include respiratory system irritation, eye irritation, softening and whitening of the skin followed by the development of painful burns, headache, dizziness, rapid and difficult breathing, weakness, collapse, abdominal pain, nausea, vomiting, internal damage, digestive disturbances, nervous disorders, skin eruptions, liver and kidney damage and dermatitis. Other symptoms may include coma, painless blanching or erythema, corrosion, profuse sweating, intense thirst, diarrhea, cyanosis from methemoglobinemia, hyperactivity, stupor, decrease in blood pressure, hyperpnea, hemolysis, convulsions, pulmonary edema followed by pneumonia, jaundice, oliguria, anuria and skin sensitivity reactions. Skin contact may result in central nervous system damage, cerebral edema and muscle contractions. ACUTE/CHRONIC HAZARDS: A related compound may be absorbed through the skin. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
For advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious or in respiratory arrest. Positive-pressure ventilation techniques with a bag-valve-mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias if necessary . Start an IV with D5W TKO /SRP: To keep open, "minimal flow rate"/. Use lactated Ringer's if signs of hypovolemia are present. Watch for signs of fluid overload. Consider drug therapy for pulmonary edema . For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors for hypotension with a normal fluid volume. Watch for signs of fluid overload . Administer 1% solution methylene blue if patient is symptomatic with severe hypoxia, cyanosis, and cardiac compromise not responding to oxygen. . Treat seizures with diazepam (Valium). ... Use proparacaine hydrochloride to assist eye irrigation . Phenols and related compounds/
SECTION 5: Firefighting measures
Suitable extinguishing media
Extinguish fire using agent suitable for type of surrounding fire. Material itself does not burn or burns with difficulty.
Specific hazards arising from the chemical
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)
Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
Special protective actions for fire-fighters
Use foam, dry powder, carbon dioxide.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
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. Carefully collect remainder. Then store and dispose of according to local regulations.
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. Carefully collect remainder. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
Land Spill: Dig a pit, pond, lagoon, or holding area /SRP: If time permits, pits, ponds, lagoons, soa holes, or holding areas should be sealed with an impermeable flexible membrane liner./ to contain liquid or solid material. Cover solids with plastic sheet to prevent dissolving in rain or fire fighting water.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames. Above 62°C use a closed system and ventilation. 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
Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. Separated from strong oxidants and food and feedstuffs.

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and on burning. This produces toxic fumes. Reacts with oxidants, acid anhydrides and acid chlorides.
Chemical stability
no data available
Possibility of hazardous reactions
Non-combustiblePhenols, such as TRICHLOROPHENOL, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has pKa = 9.88). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid.

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.
