Air & Water Reactions
Sensitive to light and air. Insoluble in water.
Fire Hazard
Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases. This material may burn but does not ignite readily. Container may explode in heat of fire. Slight explosion and fire hazard in the form of vapor when exposed to heat or flame. When heated to decomposition, it emits highly toxic fumes. Reacts violently with nitric acid, oleum, and chlorosulfonic acid. Hazardous polymerization may not occur. (EPA, 1998)
Health Hazard
The chemical is rated as a very toxic compound with a probable oral lethal dose in humans of 50-500 mg/kg, or between 1 teaspoon and 1 ounce for a 70 kg (150 lb.) person. It is a strong dermal irritant and frequently causes dermatitis. Serious or fatal poisoning may result if large areas of skin are wet with cresol, o- and the substance is not removed immediately. Ingestion of even a small amount may cause paralysis and coma. It is corrosive to body tissues, with toxicity similar to phenol. (EPA, 1998)
Reactivity Profile
O-CRESOL is incompatible with oxidizing agents and bases. Mixing it with chlorosulfonic acid, nitric acid and oleum in a closed contained caused the temperature and pressure to increase. (NTP, 1992)
Belongs to the Following Reactive Group(s)

Firefighting
Use water to keep fire-exposed containers cool. Fight fire from a maximum distance. Dike fire control water for later disposal; don't scatter the material. Wear positive pressure breathing apparatus and full protective clothing. Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Remove and isolate contaminated clothing at the site.
Water to blanket the fire and dry chemical, foam, or carbon dioxide to extinguish the flames. Extinguish small fires with dry chemical, carbon dioxide, water spray, or foam. For large fires use water spray, fog, or foam. Move container from fire area if you can do so without risk. (EPA, 1998)

Non-Fire Response
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Neutralize spilled material with crushed limestone, soda ash, or lime. Apply water spray or mist to knock down vapors. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Neutralize with agricultural lime (CaO), crushed limestone (CaCO3) or sodium bicarbonate (NaHCO3). Absorb bulk liquid with fly ash or cement powder. Water spill: Use natural barriers or oil spill control booms to limit spill travel. Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. (AAR, 2003)
Protective Clothing
Skin: Wear appropriate personal protective clothing to prevent skin contact.
Eyes: Wear appropriate eye protection to prevent eye contact.
Wash skin: The worker should immediately wash the skin when it becomes contaminated.
Remove: Work clothing that becomes wet or significantly contaminated should be removed and replaced.
Change: Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premise.
Provide: Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substance; this is irrespective of the recommendation involving the wearing of eye protection. Facilities for quickly drenching the body should be provided within the immediate work area for emergency use where there is a possibility of exposure. [Note: It is intended that these facilities provide a sufficient quantity or flow of water to quickly remove the substance from any body areas likely to be exposed. The actual determination of what constitutes an adequate quick drench facility depends on the specific circumstances. In certain instances, a deluge shower should be readily available, whereas in others, the availability of water from a sink or hose could be considered adequate.] (NIOSH, 2003)

First Aid
Warning: Effects may be delayed. Caution is advised. Vital signs should be monitored closely.
Signs and Symptoms of Acute o-Cresol Exposure: Signs and symptoms of acute exposure to o-cresol may include a weak pulse, hypotension (low blood pressure), tachycardia (rapid heart rate), cardiac arrhythmias, and cardiac failure. Tachypnea (rapid respiratory rate), pulmonary edema, and respiratory arrest or failure may be noted. Weakness, headache, dizziness, tinnitus (ringing in the ears), shock, and delirium are common. Seizures may occur and are often followed by coma. Pallor, sweating, dilated pupils, and a profound drop in body temperature may also be found. Gastrointestinal effects include nausea, abdominal pain, bloody vomitus, and bloody diarrhea. Renal insufficiency may lead to hematuria (bloody urine). o-Cresol is corrosive to the skin, eyes, and mucous membranes. Contact may result in severe and painful burns, which promptly become anesthetized (numb) to touch and pain. Ulceration may occur.
Emergency Life-Support Procedures: Acute exposure to o-cresol may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.
Inhalation Exposure:
1. Move victims to fresh air. Emergency personnel should avoid self-exposure to o-cresol.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.
3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
4. Transport to a health care facility.
Dermal/Eye Exposure:
1. Remove victims from exposure. Emergency personnel should avoid self- exposure to o-cresol.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.
3. Remove contaminated clothing as soon as possible.
4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes.
5. Wash exposed skin areas with undiluted polyethylene glycol 300 or 400. If polyethylene glycol is unavailable, use water. Follow initial polyethylene glycol or water wash with a second (water) wash.
6. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
7. Transport to a health care facility.
Ingestion Exposure:
1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.
2. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
3. Immediately give conscious and alert victims water or milk: children up to 1 year old, 125 mL (4 oz or 1/2 cup); children 1 to 12 years, 200 mL (6 oz or 3/4 cup); adults, 250 mL (8 oz or 1 cup). Do not exceed 250 mL (8 oz or 1 cup).
4. Activated charcoal may be administered if victims are conscious and alert. Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water.
5. Promote excretion by administering a saline cathartic or sorbitol to conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz) of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults.
