Guidance on Safe Use

First-aid measures

Eye: Flush eyes with water immediately while holding the eyelids open. Remove contact lenses, if worn, after initial flushing, and continue flushing for at least 15 minutes.  Get immediate medical attention.

Skin: No specific first aid measures are required.  As a precaution, remove clothing and shoes if contaminated.  To remove the material from skin, apply a waterless hand cleaner, mineral oil, or petroleum jelly. Then wash with soap and water.  Discard contaminated clothing and shoes or thoroughly clean before reuse.

Ingestion: No specific first aid measures are required.  Do not induce vomiting.  As a precaution, get medical advice.

Inhalation: No specific first aid measures are required.  If exposed to excessive levels of material in the air, move the exposed person to fresh air.  Get medical attention if coughing or respiratory discomfort occurs.

Fire-fighting measures

FLAMMABLE PROPERTIES:

Flashpoint:   (Cleveland Open Cup)  160 °C (320 °F)   Minimum

Autoignition:   No data available

Flammability (Explosive) Limits (% by volume in air):  Lower:  No data available Upper:  No data available

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

PROTECTION OF FIRE FIGHTERS:

Fire Fighting Instructions: This material will burn although it is not easily ignited.  For fires involving this material, do not enter any enclosed or confined fire space without proper protective equipment, including self-contained breathing apparatus.

Combustion Products:   Highly dependent on combustion conditions.  A complex mixture of airborne solids, liquids, and gases including carbon monoxide, carbon dioxide, and unidentified organic compounds will be evolved when this material undergoes combustion.    Combustion may form oxides of: Sulfur, Phosphorus, Zinc  .

Accidental release measures

Protective Measures:  Eliminate all sources of ignition in vicinity of spilled material.

Spill Management:  Stop the source of the release if you can do it without risk.   Contain release to prevent further contamination of soil, surface water or groundwater.  Clean up spill as soon as possible, observing precautions in Exposure Controls/Personal Protection.  Use appropriate techniques such as applying non-combustible absorbent materials or pumping.  Where feasible and appropriate, remove contaminated soil.  Place contaminated materials in disposable containers and dispose of in a manner consistent with applicable regulations.

Reporting:  Report spills to local authorities as appropriate or required.

Handling and storage

Precautionary Measures: Proper handling and storage temperatures for this material are time and temperature dependent and are necessary to avoid decomposition that releases hazardous fumes described in MSDS Section 3 (Potential Health Effects) and Section 10 (Stability and Reactivity).    If adequate engineering controls are used, short term activities such as loading, unloading and in-line blending may occur at temperatures ranging from 80-85°C (176-185°F).  During shipment by railcar or tank truck, loading temperatures as high as 80-85°C (176-185°F) may be used and are expected to drop to 66°C (150°F) or lower within 7 days. Storage temperatures for up to 2 weeks should not exceed 66°C (150°F). The recommended long-term (2 weeks or more) storage temperature is ambient to 45°C (113°F) maximum.   Do not get in eyes, on skin, or on clothing.  Do not breathe vapor or fumes.  Wash thoroughly after handling.

Unusual Handling Hazards: Toxic quantities of hydrogen sulfide (H2S) may be present in storage tanks and bulk transport vessels which contain or have contained this material.  Persons opening or entering these compartments should first determine if H2S is present.  See Exposure Controls/Personal Protection -Section 8.  Do not attempt rescue of a person over exposed to H2S without wearing approved supplied-air or self-contained breathing equipment.  If there is a potential for exceeding one-half the occupational exposure standard, monitoring of hydrogen sulfide levels is required.  Since the sense of smell cannot be relied upon to detect the presence of H2S, the concentration should be measured by the use of fixed or portable devices.

General Handling Information: The recommended reheating medium is hot water or regulated low pressure steam. Care must be taken not to exceed the temperatures stated above when reheating this material in order to avoid decomposition that releases hazardous fumes.  Avoid contaminating soil or releasing this material into sewage and drainage systems and bodies of water.

Static Hazard: Electrostatic charge may accumulate and create a hazardous condition when handling this material. To minimize this hazard, bonding and grounding may be necessary but may not, by themselves, be sufficient. Review all operations which have the potential of generating and accumulating an electrostatic charge and/or a flammable atmosphere (including tank and container filling, splash filling, tank cleaning, sampling, gauging, switch loading, filtering, mixing, agitation, and vacuum truck operations) and use appropriate mitigating procedures.

General Storage Information: In normal storage conditions, the shelf life of this product is 5 years.

Container Warnings: Container is not designed to contain pressure. Do not use pressure to empty container or it may rupture with explosive force.  Empty containers retain product residue (solid, liquid, and/or vapor) and can be dangerous.  Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, static electricity, or other sources of ignition.  They may explode and cause injury or death.  Empty containers should be completely drained, properly closed, and promptly returned to a drum reconditioner or disposed of properly.

Exposure controls / personal protection

GENERAL CONSIDERATIONS:

Consider the potential hazards of this material (see Section 3), applicable exposure limits, job activities, and other substances in the work place when designing engineering controls and selecting personal protective equipment.  If engineering controls or work practices are not adequate to prevent exposure to harmful levels of this material, the personal protective equipment listed below is recommended.  The user should read and understand all instructions and limitations supplied with the equipment since protection is usually provided for a limited time or under certain circumstances. Refer to appropriate CEN standards.

ENGINEERING CONTROLS:

Use in a well-ventilated area.

PERSONAL PROTECTIVE EQUIPMENT

Eye/Face Protection: Wear protective equipment to prevent eye contact. Selection of protective equipment may include safety glasses, chemical goggles, face shields, or a combination depending on the work operations conducted.

Skin Protection: No special protective clothing is normally required.  Where splashing is possible, select protective clothing depending on operations conducted, physical requirements and other substances in the workplace.  Suggested materials for protective gloves include:  Nitrile Rubber, Silver Shield, Viton.

Respiratory Protection: No respiratory protection is normally required.   If material is heated and emits hydrogen sulfide, determine if airborne concentrations are below the occupational exposure limit for hydrogen sulfide.  If not, wear an approved positive pressure air-supplying respirator.  For more information on hydrogen sulfide, see Chevron MSDS No. 301.  If user operations generate an oil mist, determine if airborne concentrations are below the occupational exposure limit for mineral oil mist.  If not, wear an approved respirator that provides adequate protection from the measured concentrations of this material.  For air-purifying respirators use a particulate cartridge.

No applicable occupational exposure limits exist for this material or its components.  Consult local authorities for appropriate values.
