4. FIRST AID MEASURES 

INHALATION: If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not 

breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate 

medical attention. 

SKIN CONTACT: For thermal burns, cool affected areas as quickly as possible by drenching or immersing 

in water. Wash skin with soap and water for at least 15 minutes, or use a waterless handcleaner, while 

removing contaminated clothing and shoes. Get immediate medical attention, if needed. 
EYE CONTACT: Immediately flush eyes with plenty of water for at least 15 minutes. Get medical 

attention, if needed. 

INGESTION: DO NOT induce vomiting. If a large amount is swallowed, get medical attention. Do not give 

anything by mouth to unconscious or convulsive person. If vomiting occurs, keep head lower than hips to 

help prevent aspiration. 

5. FIRE FIGHTING MEASURES 

FIRE AND EXPLOSION HAZARDS: During fire conditions, vapors and decomposition products may be 

released, forming flammable/explosive mixtures in air. Containers may rupture or explode if exposed to heat. 

EXTINGUISHING MEDIA: regular dry chemical, carbon dioxide, regular foam, water spray 

FIRE FIGHTING: Avoid inhalation of material or combustion by-products. Stay upwind and keep out of 

low areas. Use extinguishing agents appropriate for surrounding fire. Flood with fine water spray. Directly 

spraying water or foam onto hot burning product may cause frothing. 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. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tanks 

due to fire. 

FIRE FIGHTING PROTECTIVE EQUIPMENT: Full fire fighting turn-out gear (bunker gear). 

SENSITIVITY TO MECHANICAL IMPACT: No 

SENSITIVITY TO STATIC DISCHARGE: Yes (dust) 

FLASH POINT: >374 F (>190 C) (PMCC) 

AUTOIGNITION: >750 F (>399 C) 

FLAMMABILITY CLASS (OSHA): IIIB 

6. ACCIDENTAL RELEASE MEASURES 

WATER RELEASE:

Subject to California Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). Keep out of 

water supplies and sewers. 

OCCUPATIONAL RELEASE:

Stop leak if possible without personal risk. Small spills: Absorb with sand or other non-combustible material. 

Collect spilled material in appropriate container for disposal. In Canada, report releases to provincial 

authorities, municipal authorities, or both, as required. Due to the concentration of Benzo(a)pyrene and the 

CERCLA (40 CFR 302.4) reportable quantity of 1 pound, the release of 70 pounds (6 gallons) of this product 

requires National Response Center notification. 
7. HANDLING AND STORAGE 

STORAGE: Store and handle in accordance with all current regulations and standards. Label all containers. 

Keep container in a well-ventilated place. Keep away from heat, sparks and flame. Protect from physical 

damage. Notify State Emergency Response Commission for storage or use at amounts greater than or equal 

to the TPQ (U.S. EPA SARA Section 302). SARA Section 303 requires facilities storing a material with a 

TPQ to participate in local emergency response planning (U.S. EPA 40 CFR 355.30). 

HANDLING: Avoid breathing vapors of heated materials. Avoid contact with eyes, skin and clothing. 

When using, do not eat, drink or smoke. Wash exposed areas thoroughly with soap and water, or a waterless 

handcleaner, after skin contact and before eating, drinking, using tobacco products, or restrooms. Use 

protective skin cream on exposed skin before and during work shift. To reduce sun sensitivity a sun-blocking 

lotion (SPF 15+) can also be applied prior to application of a protective cream. Contaminated clothing 

should be removed and laundered before reuse. 

8. EXPOSURE CONTROLS, PERSONAL PROTECTION 

EXPOSURE LIMITS:

HIGH-TEMP. COAL TAR PITCH:

COAL TAR PITCH VOLATILES:

0.2 mg/m3 OSHA TWA (benzene soluble fraction) 

0.2 mg/m3 ACGIH TWA (benzene soluble fraction)

VENTILATION: Ensure adequate ventilation. Ensure compliance with applicable exposure limits. 

EYE PROTECTION: ANSI Z87.1-1989 approved safety glasses with side shields. Provide an emergency 

eye wash fountain and quick drench shower in the immediate work area. At elevated temperatures: A 

faceshield is recommended. 

CLOTHING: Wear protective clothing to prevent contact. Use protective skin cream on exposed skin 

before and during work shift. Contaminated clothing should be removed and laundered before reuse. When 

material is at an elevated temperature, wear appropriate heat resistant clothing. 

GLOVES: Wear appropriate gloves. When material is at an elevated temperature, wear appropriate heat 

resistant gloves. 

PROTECTIVE MATERIAL TYPES: protective skin creams, chemical resistant material, heat resistant 

material 

RESPIRATOR: If the applicable TLVs and/or PELs are exceeded, use canister or cartridge respirators, 

which are MSHA/NIOSH-approved, with organic vapor cartridges.

11. TOXICOLOGICAL INFORMATION 

CARBON PITCH LIQUID:

CARCINOGEN STATUS: OSHA: No, NTP: Yes, IARC: Yes, (See below for additional information on 

component carcinogen status) 

TARGET ORGANS: respiratory tract system, skin, eyes, bladder, scrotum 

MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: respiratory disorders, skin disorders, 

central nervous system disorders (i.e. headache, drowsiness, dizziness, loss of coordination) 

ADDITIONAL DATA: This product is coal tar pitch. Volume 35 of the IARC monograph states that there 

is sufficient evidence that coal tar pitches are carcinogenic in humans. IARC's conclusion is based upon 

studies suggesting an association between skin cancer and chronic occupational dermal exposure to coal tar 

pitches and upon other historical studies and anecdotal reports showing an association between dermal 

exposure to coal tar pitch and scrotal cancer in the absence of good hygiene practices. 
Epidemiological studies of aluminum reduction workers showed an excess risk of developing bladder cancer 

for workers with chronic inhalation overexposure to coal tar pitch volatiles in excess of the recommended 

permissible exposure level. Studies also suggest an association between lung cancer and chronic inhalation 

overexposure to coal tar pitch volatiles in excess of the recommended permissible exposure level. A recent 

animal study may suggest an association between lung cancer and pulmonary deposition of particulate matter 

originating from coal tar pitches. It is not anticipated, however, that use of this product in liquid form will 

create a respirable dust.

Sufficient Evidence, Group 1; ACGIH: A1 -Confirmed Human Carcinogen (Coal tar pitch volatiles)
