Health Hazard
This compound is highly toxic by ingestion. (EPA, 1998)
Reactivity Profile
PHENOL, 2,2'-THIOBIS-4-CHLORO-6-METHYL- is a halogenated organosulfide and phenol. Incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials may generate heat and toxic or flammable gas. Heat is also generated by the acid-base reaction with bases.

First Aid
Warning: Effects may be delayed. Caution is advised. Vital signs should be monitored closely.

Signs and Symptoms of Acute Phenol, 2,2'-thiobis(4-chloro-6- methyl)- Exposure: Signs and symptoms of acute exposure to phenol, 2,2'-thiobis(4 chloro-6-methyl)- 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 profound and followed by coma. Pallor, sweating, dilated pupils, drop in body temperature may also be found. Gastrointestinal effects include nausea, abdominal pain, bloody vomitus, and bloody diarrhea. Hematuria (bloody urine) may be noted. Phenol, 2,2'-thiobis(4-chloro-6-methyl)- 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 phenol, 2,.2'-thiobis(4-chloro-6-methyl)- 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 as necessary, air respiratory equipment should also be worn. 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 phenol, 2,2'-thiobis(4- chloro-6-methyl)-.
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 phenol, 2,2'-thiobis(4-chloro-6-methyl)-.
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 and isolate 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.
6. Rush to a health care facility. (EPA, 1998)

The Physical Property fields include properties such as vapor pressure and boiling point, as well as explosive limits and toxic exposure thresholds The information in CAMEO Chemicals comes from a variety of data sources.

Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
