SECTION 2 COMPOSITION / INFORMATION ON INGREDIENTS

No Reportable Hazardous Substance(s) or Complex Substance(s).

SECTION 3 HAZARDS IDENTIFICATION

This material is not considered to be hazardous according to regulatory guidelines (see (M)SDS Section 15).

POTENTIAL HEALTH EFFECTS

Low order of toxicity. Excessive exposure may result in eye, skin, or respiratory irritation. High-pressure
injection under skin may cause serious damage.

NFPA Hazard ID: Health: 0 Flammability: 1 Reactivity: 0

HMIS Hazard ID: Health: 0 Flammability: 1 Reactivity: 0

NOTE: This material should not be used for any other purpose than the intended use in Section 1 without expert
advice. Health studies have shown that chemical exposure may cause potential human health risks which may vary
from person to person.

SECTION 4 FIRST AID MEASURES

INHALATION
Remove from further exposure. For those providing assistance, avoid exposure to yourself or others. Use
adequate respiratory protection. If respiratory irritation, dizziness, nausea, or unconsciousness occurs, seek
immediate medical assistance. If breathing has stopped, assist ventilation with a mechanical device or use

mouth-to-mouth resuscitation.

SKIN CONTACT
Wash contact areas with soap and water. If product is injected into or under the skin, or into any part of the
body, regardless of the appearance of the wound or its size, the individual should be evaluated immediately by
a physician as a surgical emergency. Even though initial symptoms from high pressure injection may be
minimal or absent, early surgical treatment within the first few hours may significantly reduce the ultimate extent
of injury.

EYE CONTACT
Flush thoroughly with water. If irritation occurs, get medical assistance.

INGESTION
First aid is normally not required. Seek medical attention if discomfort occurs.

SECTION 5 FIRE FIGHTING MEASURES

EXTINGUISHING MEDIA
Appropriate Extinguishing Media: Use water fog, foam, dry chemical or carbon dioxide (CO2) to extinguish
flames.

Inappropriate Extinguishing Media: Straight Streams of Water

FIRE FIGHTING
Fire Fighting Instructions: Evacuate area. Prevent runoff from fire control or dilution from entering streams,
sewers, or drinking water supply. Firefighters should use standard protective equipment and in enclosed
spaces, self-contained breathing apparatus (SCBA). Use water spray to cool fire exposed surfaces and to
protect personnel.

Hazardous Combustion Products: Aldehydes, Oxides of carbon, Sulfur oxides, Smoke, Fume, Incomplete
combustion products

SECTION 6 ACCIDENTAL RELEASE MEASURES

NOTIFICATION PROCEDURES
In the event of a spill or accidental release, notify relevant authorities in accordance with all applicable
regulations. U.S. regulations require reporting releases of this material to the environment which exceed the
reportable quantity or oil spills which could reach any waterway including intermittent dry creeks. The National
Response Center can be reached at (800)424-8802.

SPILL MANAGEMENT
Land Spill: Stop leak if you can do it without risk. Recover by pumping or with suitable absorbent.

______________________________________________________________________________________________________________________

Water Spill: Stop leak if you can do it without risk. Confine the spill immediately with booms. Warn other
shipping. Remove from the surface by skimming or with suitable absorbents. Seek the advice of a
specialist before using dispersants.

Water spill and land spill recommendations are based on the most likely spill scenario for this material;
however, geographic conditions, wind, temperature, (and in the case of a water spill) wave and current direction
and speed may greatly influence the appropriate action to be taken. For this reason, local experts should be
consulted. Note: Local regulations may prescribe or limit action to be taken.

ENVIRONMENTAL PRECAUTIONS
Large Spills: Dike far ahead of liquid spill for later recovery and disposal. Prevent entry into waterways,
sewers, basements or confined areas.

SECTION 7 HANDLING AND STORAGE

HANDLING
Prevent small spills and leakage to avoid slip hazard.

Static Accumulator: This material is a static accumulator.

STORAGE
Do not store in open or unlabelled containers.

SECTION 8 EXPOSURE CONTROLS / PERSONAL PROTECTION

Exposure limits/standards for materials that can be formed when handling this product: When mists / aerosols
can occur, the following are recommended: 5 mg/m³ - ACGIH TLV, 10 mg/m³ - ACGIH STEL, 5 mg/m³ - OSHA PEL.

NOTE: Limits/standards shown for guidance only. Follow applicable regulations.

ENGINEERING CONTROLS

The level of protection and types of controls necessary will vary depending upon potential exposure conditions.
Control measures to consider:
No special requirements under ordinary conditions of use and with adequate ventilation.

PERSONAL PROTECTION

Personal protective equipment selections vary based on potential exposure conditions such as applications,
handling practices, concentration and ventilation. Information on the selection of protective equipment for use
with this material, as provided below, is based upon intended, normal usage.

Respiratory Protection: If engineering controls do not maintain airborne contaminant concentrations at a

level which is adequate to protect worker health, an approved respirator may be appropriate. Respirator
selection, use, and maintenance must be in accordance with regulatory requirements, if applicable. Types of
 Product Name: MOBIL DTE OIL HEAVY MEDIUM

______________________________________________________________________________________________________________________
respirators to be considered for this material include:
No special requirements under ordinary conditions of use and with adequate ventilation.

For high airborne concentrations, use an approved supplied-air respirator, operated in positive pressure mode.
Supplied air respirators with an escape bottle may be appropriate when oxygen levels are inadequate,
gas/vapor warning properties are poor, or if air purifying filter capacity/rating may be exceeded.

Hand Protection: Any specific glove information provided is based on published literature and glove
manufacturer data. Work conditions can greatly effect glove durability; inspect and replace worn or damaged
gloves. The types of gloves to be considered for this material include:
No protection is ordinarily required under normal conditions of use.

Eye Protection: If contact is likely, safety glasses with side shields are recommended.

Skin and Body Protection: Any specific clothing information provided is based on published literature or
manufacturer data. The types of clothing to be considered for this material include:
No skin protection is ordinarily required under normal conditions of use. In accordance with good
industrial hygiene practices, precautions should be taken to avoid skin contact.

Specific Hygiene Measures: Always observe good personal hygiene measures, such as washing after
handling the material and before eating, drinking, and/or smoking. Routinely wash work clothing and protective
equipment to remove contaminants. Discard contaminated clothing and footwear that cannot be cleaned.
Practice good housekeeping.
