4.2 Fire Hazard

Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

4.3 Other Preventative Measures

Wash contaminated areas of skin with concentrated soap solution without delay. Contaminated gloves, clothing, shoes should be immediately removed and disposed of in an incinerator. /4-Chlorophenol/
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers.

4.4 Hazard Class

4.4 Hazard Declaration

H302 + H312-H317-H318-H400

4.4 Cleanup Methods

Activated carbon is a good method for removing chlorophenols from water. Competitive adsorption occurs between chlorophenols and humic substances present in nearly all municipal water supplies. This competition decreases the capacity of carbon for chlorophenols. /Chlorophenols/

4.5 DisposalMethods

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number U039, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.
A good candidate for rotary kiln incineration at a temperature range of 820 to 1,600 deg C and residence times of seconds for liquids and gases, and hours for solids.
A pilot plant study was conducted to evaluate the fate and behavior of 22 toxic organic compounds in conventional activated sludge wastewater treatment plants. The organic cmpd, 3-methyl-4-chlorophenol, spiked at a nominal concn of 50 ug/l was about 95-98% removable. Results showed that biodegradability was variable & was a function of molecular structure.

4.6 DOT Emergency Guidelines

/GUIDE 152: SUBSTANCES - TOXIC (COMBUSTIBLE)/ Health: Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. 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. /Chlorocresols; Chlorocresols, liquid; Chlorocresols, solid; Chlorocresols, solution/
/GUIDE 152: SUBSTANCES - TOXIC (COMBUSTIBLE)/ Fire or Explosion: Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. /Chlorocresols; Chlorocresols, liquid; Chlorocresols, solid; Chlorocresols, solution/
/GUIDE 152: SUBSTANCES - TOXIC (COMBUSTIBLE)/ Public Safety: CALL Emergency Response Telephone Number ... . As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. /Chlorocresols; Chlorocresols, liquid; Chlorocresols, solid; Chlorocresols, solution/
/GUIDE 152: SUBSTANCES - TOXIC (COMBUSTIBLE)/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible. /Chlorocresols; Chlorocresols, liquid; Chlorocresols, solid; Chlorocresols, solution/
/GUIDE 152: SUBSTANCES - TOXIC (COMBUSTIBLE)/ Evacuation: ... Fire: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. /Chlorocresols; Chlorocresols, liquid; Chlorocresols, solid; Chlorocresols, solution/
/GUIDE 152: SUBSTANCES - TOXIC (COMBUSTIBLE)/ Fire: Small fires: Dry chemical, CO2 or water spray. Large fires: Water spray, fog or regular foam. Move containers from fire area if you can do it without risk. Dike fire control water for later disposal; do not scatter the material. Use water spray; do not use straight streams. Fire involving tanks or car/trailer loads: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. /Chlorocresols; Chlorocresols, liquid; Chlorocresols, solid; Chlorocresols, solution/
/GUIDE 152: SUBSTANCES - TOXIC (COMBUSTIBLE)/ Spill or Leak: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Cover with plastic sheet to prevent spreading . Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. /Chlorocresols; Chlorocresols, liquid; Chlorocresols, solid; Chlorocresols, solution/
/GUIDE 152: SUBSTANCES - TOXIC (COMBUSTIBLE)/ First Aid: Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. /Chlorocresols; Chlorocresols, liquid; Chlorocresols, solid; Chlorocresols, solution/
