Potential Health Effects:

Eye: Contact may cause mild eye irritation including stinging, watering, and redness.

Skin: Mild to moderate skin irritant. Contact may cause redness, itching, burning, and skin damage.Prolonged or repeated contact may cause drying and cracking of the skin, dermatitis (inflammation),burns, and severe skin damage. Not acutely toxic by skin absorption, but prolonged or repeated skincontact may be harmful (see Section 11).

Inhalation (Breathing): Expected to have a low degree of toxicity by inhalation.

Ingestion (Swallowing): Low degree of toxicity by ingestion. ASPIRATION HAZARD - This material can enter lungs during swallowing or vomiting and cause lung inflammation and damage.

Signs and Symptoms: Effects of overexposure may include irritation of the nose and throat,irritation of the digestive tract, nausea, vomiting, transient excitation followed by signs of nervoussystem depression (e.g., headache, drowsiness, dizziness, loss of coordination, disorientation andfatigue) and pneumonitis (inflammation of the lungs).

Cancer: Skin cancer hazard (see Sections 11 and 15).

Target Organs: Inadequate data available for this material.

Developmental: Inadequate evidence available for this material. See Section 11 for developmental toxicity information of individual components, if any.

Other Comments: Reports have associated repeated and prolonged occupational overexposureto solvents with permanent brain and nervous system damage (sometimes referred to as Solvent or Painters'Syndrome). Intentional misuse by deliberately concentrating and inhaling this material may be harmful orfatal.

Pre-Existing Medical Conditions: Conditions aggravated by exposure may include skindisorders and respiratory (asthma-like) disorders.


Eye: If irritation or redness develops, move victim away from exposure and into fresh air. Flush eyeswith clean water. If symptoms persist, seek medical attention.

Skin: Remove contaminated shoes and clothing, and flush affected area(s) with large amounts of water. If skin surface is damaged, apply a clean dressing and seek medical attention. If skin surface is notdamaged, cleanse affected area(s) thoroughly by washing with mild soap and water. If irritation or redness develops, seek medical attention.

Inhalation (Breathing): If respiratory symptoms develop, move victim away from source of exposure and intofresh air. If symptoms persist, seek medical attention. If victim is not breathing, clear airway and immediatelybegin artificial respiration. If breathing difficulties develop, oxygen should be administered by qualifiedpersonnel. Seek immediate medical attention.

Ingestion (Swallowing): Aspiration hazard: Do not induce vomiting or give anything by mouth because thismaterial can enter the lungs and cause severe lung damage. If victim is drowsy or unconscious andvomiting, place on the left side with the head down. If possible, do not leave victim unattended and observeclosely for adequacy of breathing. Seek medical attention.

Note To Physicians: High-pressure hydrocarbon injection injuries may produce substantialnecrosis of underlying tissue despite an innocuous appearing external wound. Often these injuriesrequire extensive emergency surgical debridement and all injuries should be evaluated by aspecialist in order to assess the extent of injury.


Flammable Properties: Flash Point: 100-150°F/38-66°C (TCC, ASTM D-56)OSHA Flammability Class: Combustible liquid LEL%: 0.7 / UEL%: 7.0Autoignition Temperature: 410°F/210°C

Unusual Fire & Explosion Hazards: This material is flammable and can be ignited by heat, sparks, flames, orother sources of ignition (e.g., static electricity, pilot lights, or mechanical/electrical equipment, and electronicdevices such as cell phones, computers, calculators, and pagers which have not been certified as intrinsicallysafe). Vapors may travel considerable distances to a source of ignition where they can ignite, flash back, orexplode. May create vapor/air explosion hazard indoors, in confined spaces, outdoors, or in sewers. Vapors areheavier than air and can accumulate in low areas. If container is not properly cooled, it can rupture in the heat of afire.

Extinguishing Media: Dry chemical, carbon dioxide, or foam is recommended. Water spray is recommended tocool or protect exposed materials or structures. Carbon dioxide can displace oxygen. Use caution when applyingcarbon dioxide in confined spaces. Water may be ineffective for extinguishment, unless used under favorableconditions by experienced fire fighters.

Fire Fighting Instructions: For fires beyond the incipient stage, emergency responders in the immediate hazardarea should wear bunker gear. When the potential chemical hazard is unknown, in enclosed or confined spaces, orwhen explicitly required by DOT, a self contained breathing apparatus should be worn. In addition, wear other appropriate protective equipment as conditions warrant (see Section 8).

Isolate immediate hazard area, keep unauthorized personnel out. Stop spill/release if it can be done with minimal

risk. Move undamaged containers from immediate hazard area if it can be done with minimal risk.

Water spray may be useful in minimizing or dispersing vapors and to protect personnel. Cool equipment exposed tofire with water, if it can be done with minimal risk. Avoid spreading burning liquid with water used for cooling purposes.


Flammable. Keep all sources of ignition and hot metal surfaces away from spill/release. The use of explosion-proof equipment is recommended.

Stay upwind and away from spill/release. Notify persons down wind of the spill/release, isolate immediate hazardarea and keep unauthorized personnel out. Stop spill/release if it can be done with minimal risk. Wear appropriate protective equipment including respiratory protection as conditions warrant (see Section 8).

Prevent spilled material from entering sewers, storm drains, other unauthorized drainage systems, and natural waterways. Dike far ahead of spill for later recovery or disposal. Use foam on spills to minimize vapors (seeSection 5). Spilled material may be absorbed into an appropriate absorbent material.

Notify fire authorities and appropriate federal, state, and local agencies. Immediate cleanup of any spill isrecommended. If spill of any amount is made into or upon navigable waters, the contiguous zone, or adjoiningshorelines, notify the National Response Center (phone number 800-424-8802).


Handling: Open container slowly to relieve any pressure. Bond and ground all equipment whentransferring from one vessel to another. Can accumulate static charge by flow or agitation. Can be ignitedby static discharge. The use of explosion-proof equipment is recommended and may be required (seeappropriate fire codes). Refer to NFPA-704 and/or API RP 2003 for specific bonding/grounding requirements.

Do not enter confined spaces such as tanks or pits without following proper entry procedures such as ASTMD-4276 and 29CFR 1910.146. The use of appropriate respiratory protection is advised when concentrationsexceed any established exposure limits (see Sections 2 and 8).

Do not wear contaminated clothing or shoes. Keep contaminated clothing away from sources of ignition suchas sparks or open flames. Use good personal hygiene practices.

High pressure injection of hydrocarbon fuels, hydraulic oils or greases under the skin may have seriousconsequences even though no symptoms or injury may be apparent. This can happen accidentally when usinghigh pressure equipment such as high pressure grease guns, fuel injection apparatus or from pinhole leaks intubing of high pressure hydraulic oil equipment.

"Empty" containers retain residue and may be dangerous. Do not pressurize, cut, weld, braze, solder, drill,grind, or expose such containers to heat, flame, sparks, or other sources of ignition. They may explode andcause injury or death. "Empty" drums should be completely drained, properly bunged, and promptly shipped tothe supplier or a drum reconditioner. All containers should be disposed of in an environmentally safemanner and in accordance with governmental regulations.

Before working on or in tanks which contain or have contained this material, refer to OSHA regulations, ANSIZ49.1 and other references pertaining to cleaning, repairing, welding, or other contemplated operations.

Storage: Keep container(s) tightly closed. Use and store this material in cool, dry, well-ventilatedareas away from heat, direct sunlight, hot metal surfaces, and all sources of ignition. Post area "No Smoking or Open Flame." Store only in approved containers. Keep away from any incompatible material (seeSection 10). Protect container(s) against physical damage. Outdoor or detached storage is preferred.Indoor storage should meet OSHA standards and appropriate fire codes.


Engineering controls: If current ventilation practices are not adequate to maintain airborne concentrations belowthe established exposure limits (see Section 2), additional engineering controls may be required. Where explosive

mixtures may be present, electrical systems safe for such locations must be used (see appropriate electrical codes).

Personal Protective Equipment (PPE):

Respiratory: A NIOSH certified air purifying respirator with an organic vapor cartridge maybe used under conditions where airborne concentrations are expected to exceed exposurelimits (see Section 2).

Protection provided by air purifying respirators is limited (see manufacturer's respiratorselection guide). Use a NIOSH approved self-contained breathing apparatus (SCBA) orequivalent operated in a pressure demand or other positive pressure mode if there ispotential for an uncontrolled release, exposure levels are not known, or any othercircumstances where air purifying respirators may not provide adequate protection.

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2requirements must be followed whenever workplace conditions warrant a respirator's use.

Skin: The use of gloves impervious to the specific material handled is advised to prevent skincontact, possible irritation, and skin damage. Examples of approved materials arenitrile, or Viton® (see glove manufacturer literature for information on permeability).Depending on conditions of use, apron and/or arm covers may be necessary.

Eye/Face: Approved eye protection to safeguard against potential eye contact, irritation, orinjury is recommended. Depending on conditions of use, a face shield may be necessary.

Other Protective Equipment: A source of clean water should be available in the work area for flushing eyes and skin. Impervious clothing should be worn as needed.

Suggestions for the use of specific protective materials are based on readily available publisheddata. Users should check with specific manufacturers to confirm the performance of their products.

Hydrodesulfurized Kerosene ..C9-16 (CAS# 64742-81-0)

Carcinogenicity: Application of hydrodesulfurized kerosene to mouse skin, twice a week for 12 months, resulted in an increased incidence of skin tumors. It has not been identified as a carcinogen by NTP, IARC or OSHA.

Developmental: Hydrodesulfurized kerosene applied to the skin of female rats at 494, 330, or 165 mg/kg daily for 7 consecutive weeks (premating, mating, and gestation), or for 8 consecutive weeks in males did not result in systemic, reproductive, or developmental toxicity.

Hydrotreated Distillate, Light ..C9-16 (CAS# 64742-47-8)

Carcinogenicity: Application of a similar material, hydrodesulfurized kersoene, to mouse skin, twice a week for 12 months resulted in an increased incidence of skin tumors. This material has not been identified as a carcinogen by NTP, IARC or OSHA.

Kerosene ..C9-16 (CAS# 8008-20-6)

Carcinogenicity: Application of kerosene to mouse skin, twice a week for 12 months, resulted in an increased incidence of skin tumors. It has not been identified as a carcinogen by NTP, IARC or OSHA.

Naphthalene (CAS# 91-20-3)

Carcinogenicity: Naphthalene has been evaluated in two year inhalation studies in both rats and mice. The National Toxicology Program (NTP) concluded that there is clear evidence of carcinogenicity in male and female rats based on increased incidences of respiratory epithelial adenomas and olfactory epithelial neuroblastomas of the nose. NTP found some evidence of carcinogenicity in female mice (alveolar adenomas) and no evidence of carcinogenicity in male mice. Naphthalene has been identified as a carcinogen by IARC.

When kerosenes and jet fuels escape into the environment due to leaks or spills, most of their constituent hydrocarbons will evaporate and be photodegraded by reaction with hydroxyl radicals in

the atmosphere. The half-lives in air for many of the individual hydrocarbons is less than one

day. Less volatile hydrocarbons can persist in the aqueous environment for longer periods. They

remain floating on the surface of the water; those that reach soil or sediment biodegrade

relatively slowly. Soil contaminated with jet fuel can develop adapted microbial species able to

use the fuel as a carbon source; soil aeration and nutrient supplementation can enhance this


Reported LC50/EC50 values for water-soluble fractions of kerosenes and jet fuels are usually in the

range of 10 to 100 mg/liter. Adverse effects on the gills, pseudobranch, kidney and nasal mucosa

have been reported in fish involved in spills of jet fuel. Juvenile clams may be particularly

sensitive to marine sediments contaminated as a result of spilled jet fuel. Direct toxicity and

fouling of sea birds from jet fuel can occur if birds dive through floating layers of spilled fuel.

Phytotoxic effects of jet fuel have been reported following exposure of plants to sprays or vapors.

Lack of seed germination and inhibition of seedling growth may also occur. There is evidence for

moderate bioaccumulation of the water-soluble hydrocarbons present in jet fuels.


This material, if discarded as produced, would be a RCRA "characteristic" hazardous waste due to the

characteristic(s) of ignitability (D001) and benzene (D018). If the spilled or released material impacts soil,

water, or other media, characteristic testing of the contaminated materials may be required prior to their

disposal. Further, this material, once it becomes a waste, is subject to the land disposal restrictions in 40

CFR 268.40 and may require treatment prior to disposal to meet specific standards. Consult state and local

regulations to determine whether they are more stringent than the federal requirements.

Container contents should be completely used and containers should be emptied prior to discard. Container

rinsate could be considered a RCRA hazardous waste and must be disposed of with care and in full compliance

with federal, state and local regulations. Larger empty containers, such as drums, should be returned to the

distributor or to a drum reconditioner. To assure proper disposal of smaller empty containers, consult with

state and local regulations and disposal authorities.
