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

while removing contaminated clothing and shoes. Get medical attention, if needed.



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

attention.



INGESTION: DO NOT induce vomiting. If a large amount is swallowed, get immediate 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: Contact with heat may generate toxic and/or flammable gases.

Containers may rupture or explode if exposed to heat.



EXTINGUISHING MEDIA: carbon dioxide, regular dry chemical, 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. Water may be used to blanket 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).

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. Due to the concentration of Creosote and the

CERCLA (40 CFR 302.4) reportable quantity of 1 pound, the release of 0.1 gallons (1 pound) 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 tightly closed. Protect from physical damage. Keep separated from incompatible substances.

Long term heated storage may evolve dangerous gases. 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: Do not breathe vapor or mist. Avoid contact with eyes, skin and clothing. Avoid ingestion.

When using, do not eat, drink or smoke. Wash exposed areas thoroughly with soap and water 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. Remove and launder contaminated clothing

separately from other laundry before reuse.





8. EXPOSURE CONTROLS, PERSONAL PROTECTION



EXPOSURE LIMITS:

CREOSOTE - PETROLEUM SOLUTION (PRESSURE APPLICATIONS):

Creosote is a complex mixture of variable composition, and while no odor threshold for creosote has been

established, work done at the University of California has measured the odor thresholds for one of the more

volatile components in creosote and determined that the involved odor threshold is in the part per billion

range, and well below applicable exposure limits. On the basis of these data the perception of creosote odor

in and of itself should not be taken as an indication of exposure in excess of accepted exposure limits.



Elevated temperatures during long-term storage and/or transportation may release hydrogen sulfide.

However, heat treatment testing of the distillate resulted in less than 1 ppm of hydrogen sulfide being

released into the headspace at 329 F (165 C). If necessary, see applicable exposure limits.



HYDROGEN SULFIDE:

20 ppm OSHA ceiling

50 ppm OSHA peak 10 minute(s) (once if no other measurable exposure occurs)

10 ppm ACGIH TWA

15 ppm ACGIH STEL

10 ppm (15 mg/m3) NIOSH recommended ceiling 10 minute(s)



COAL TAR CREOSOTE:

COAL TAR PITCH VOLATILES:

0.2 mg/m3 OSHA TWA (benzene soluble fraction)

0.2 mg/m3 ACGIH TWA (benzene soluble fraction)

0.1 mg/m3 NIOSH recommended TWA 10 hour(s) (cyclohexane extractable fraction)



NEEDLE COKER GAS OIL:

COAL TAR PITCH VOLATILES:

0.2 mg/m3 OSHA TWA (benzene soluble fraction)

0.2 mg/m3 ACGIH TWA (benzene soluble fraction)

0.1 mg/m3 NIOSH recommended TWA 10 hour(s) (cyclohexane extractable fraction)



NAPHTHALENE:

10 ppm (50 mg/m3) OSHA TWA

15 ppm (79 mg/m3) OSHA STEL (vacated by 58 FR 35338, June 30, 1993)

10 ppm ACGIH TWA (skin)

15 ppm ACGIH STEL (skin)

10 ppm (50 mg/m3) NIOSH recommended TWA 10 hour(s)

15 ppm (75 mg/m3) NIOSH recommended STEL



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.



CLOTHING: Individuals who enter pressure treatment cylinders and other related equipment that is

contaminated with the wood treating formulation must wear protective clothing (including overalls, jackets,

gloves and boots) impervious to the wood treatment formulations and a respirator. Protective clothing must

be changed when it shows signs of contamination. Remove and launder contaminated clothing separately

from other laundry before reuse.



GLOVES: Individuals must wear gloves impervious to the wood treatment formulations in all situations

where dermal contact with creosote is expected.



PROTECTIVE MATERIAL TYPES: Examples of impervious materials for protective clothing (e.g.

overalls, jackets, gloves and boots) required during application and handling of creosote are polyvinyl

acetate (PVA), polyvinyl chloride (PVC), Neoprene and NBR (Buna-N).



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

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

Individuals who manually open cylinder doors must wear gloves and a respirator.

"Respirator" means properly fitting, well-maintained, half-mask canister or cartridge respirators which are

MSHA/NIOSH-approved for polynuclear aromatics and organic vapors.

11. TOXICOLOGICAL INFORMATION



CREOSOTE - PETROLEUM SOLUTION (PRESSURE APPLICATIONS):

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

component carcinogen status)

TARGET ORGANS: respiratory system, skin, eyes, mucous membranes, brain, central nervous system, and

possibly the liver, kidneys, spleen, and testes

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

disorders, nervous system disorders, heart disorders, impaired liver, kidney or spleen function

ADDITIONAL DATA: This product contains coal tar creosote. Volume 35 of the IARC monograph states

that there is limited evidence that coal tar derived creosotes are carcinogenic in humans and sufficient

evidence for the carcinogenicity of creosote in experimental animals. Limitations in the human exposure

studies reviewed by IARC (including the presence of other chemicals, small study populations and not well

documented exposure levels) contributed to IARC's conclusions regarding human exposure to creosote.

When applied to the skin of mice in experimental studies, creosote produced skin tumors and in one study

produced lung tumors.



Most available information on the effects of coal tar creosote in humans comes from older occupational

studies in the wood-preserving and construction industries. Today, with the use of engineering controls and

personal protective equipment, occupational exposure to creosote components is expected to be below

permissible exposure limits (measured as CTPVs).



This product contains a heavy cracked distillate which contains various polynuclear aromatic hydrocarbons

greater than 0.1%, some of which have been reported to cause skin cancer in humans under conditions of

poor personal hygiene, prolonged and/or repeated contact, and exposure to sunlight. The distillate may

possibly also contain alkyl- and alkylbenzocarbozoles, which if absorbed through the skin, based on limited

animal studies, may cause systemic toxicity to the liver, kidneys, spleen, and/or testes.



In addition to containing information about the product as a whole, this data sheet also contains information

about individual components of the product. Information of this nature may not have been derived from

studies or data relating to this product and/or may have been derived from studies or data that did not involve

human exposure and involved animal exposure only.

POLYCYCLIC AROMATIC HYDROCARBONS:

ADDITIONAL DATA: Some polycyclic aromatic hydrocarbons (PAHs), found in coal tar complex

substances, have been reported to cause lung and skin cancer in humans under conditions of poor personal

hygiene, prolonged/repeated contact, and exposure to sunlight. The National Toxicology Program (NTP) and

IARC have independently classified various PAH compounds present in coal tar substances as reasonably

anticipated to be human carcinogens (NTP), probably carcinogenic to humans (IARC Group 2A), possibly

carcinogenic to humans (IARC Group 2B), and not classifiable as to carcinogenicity to humans (IARC

Group 3). The cancers reported in the studies upon which IARC based its conclusions involved lung, skin,

liver, stomach, kidney and blood cancers in animals. Based on the results of animal experiments PAHs may

cause injury to the liver, kidneys, lungs, blood and lymph systems. Some PAH's have also been associated

with impaired fertility, heritable genetic damage and birth defects in mice.
