If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not breathing. Get immediate medical attention. 

Wash skin with soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention, if needed. Thoroughly clean and dry contaminated clothing and shoes before reuse. 

Flush eyes with plenty of water for at least 15 minutes. Then get immediate medical attention. 

If a large amount is swallowed, get medical attention. 

amyl nitrite, inhalation; sodium nitrite, intravenous; pyridoxine, intravenous; urea, intravenous. CAUTION! Get medical attention immediately. 

See Section 9 for Flammability Properties 

Severe explosion hazard. Vapor/air mixtures are explosive. The vapor is heavier than air. Vapors or gases may ignite at distant ignition sources and flash back. 

regular dry chemical, carbon dioxide, water, regular foam Large fires: Use regular foam or flood with fine water spray. 

Move container from fire area if it can be done without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks. For fires in cargo or storage area: Cool containers with water from unmanned hose holder or monitor nozzles until well after fire is out. If this is impossible then take the following precautions: Keep unnecessary people away, isolate hazard area and deny entry. Let the fire burn. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tanks due to fire. For tank, rail car or tank truck: Evacuation radius: 800 meters (1/2 mile). Water may be ineffective. 

Avoid heat, flames, sparks and other sources of ignition. Stop leak if possible without personal risk. Reduce vapors with water spray. Small spills: Absorb with sand or other non-combustible material. Collect spilled material in appropriate container for disposal. Large spills: Dike for later disposal. Remove sources of ignition. Keep unnecessary people away, isolate hazard area and deny entry. 

Store and handle in accordance with all current regulations and standards. Subject to storage regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding required. Keep separated from incompatible substances. 

Component Exposure Limits 

Biological limit value 

Provide local exhaust ventilation system. Ventilation equipment should be explosion-resistant if explosive concentrations of material are present. Ensure compliance with applicable exposure limits. 

Eyes/Face Wear splash resistant safety goggles. Provide an emergency eye wash fountain and quick drench shower in the immediate work area. 

Wear appropriate chemical resistant clothing. 

Wear appropriate chemical resistant gloves. 

Under conditions of frequent use or heavy exposure, respiratory protection may be needed. Respiratory protection is ranked in order from minimum to maximum. Consider warning properties before use. Any powered, air-purifying respirator with a full facepiece and organic vapor and acid gas cartridge(s). Any chemical cartridge respirator with a full facepiece and organic vapor and acid gas cartridge(s). For Unknown Concentrations or Immediately Dangerous to Life or Health - Any supplied-air respirator with a full facepiece that is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode. Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode. 

alcohol, ether, liquid hydrogen sulfide 

Stable at normal temperatures and pressure. 

Avoid heat, flames, sparks and other sources of ignition. Containers may rupture or explode if exposed to heat. Keep out of water supplies and sewers. 

acids, oxidizing materials, 

TERT-BUTYL MERCAPTAN: ACID OR ACID FUMES: May react to produce toxic and flammable vapors. OXIDIZERS (STRONG): Fire and explosion hazard. MERCAPTANS: CALCIUM HYPOCHLORITE: Violent reaction.

hydrogen sulfide, oxides of sulfur, carbon 

Thermal decomposition products: hydrogen sulfide, oxides of sulfur, carbon.

Will not polymerize.

Component Carcinogenicity

None of this product's components are listed by ACGIH, IARC, NTP, DFG or OSHA

THIOLS: Thiols may cause upper respiratory tract irritation Thiols containing 8 carbons have been associated with analeptic and psycomimetic effects Other thiols may cause central nervous system depression Symptoms of exposure may include cyanosis, cold extremities, rapid pulse, dyspnea, fever, irreversible depression of cerebral function, convulsions, respiratory paralysis, coma, and death Delayed pulmonary edema, renal damage with hematuria and albuminuria, and hepatic damage have also been reported Exposure to >50 ppm may cause headache, nausea, vomiting, diarrhea, dizziness, muscle weakness, and unconsciousness.

THIOLS No data available.

THIOLS: Contact with vapor or liquid may cause irritation Forty of forty-four low molecular weight thiols tested caused delayed contact-type dermatitis Sensitization and dermal irritancy are low up to C-6, increase to C-8, level off to C-12, and diminish rapidly thereafter.

THIOLS Repeated or prolonged exposure may cause dermatitis.
