First-aid measures

Skin Contact

Immediately take off all contaminated clothing. For skin contact, flush with large amounts of water. If any adverse effects persist, get medical attention. The signs and symptoms that may result from an emergency or an unexpected acute overexposure include: rash to irritation to burns.

Eye Contact

For eye contact, rinse immediately with plenty of water. Seek medical advice. The signs and symptoms that may result from an emergency or an unexpected acute overexposure include: irritation to burns.

Inhalation

Move person to non-contaminated air. If not breathing, give artificial respiration, preferably mouth-to mouth. If breathing is difficult, give oxygen. Seek medical attention. The signs and symptoms that may result from an emergency or an unexpected acute overexposure include: irritation – respiratory tract.

Ingestion

If the material is swallowed, get immediate medical attention or advice. Never give anything by mouth to a victim who is unconscious or is having convulsions. If patient has a good gag reflex, you can consider giving several ounces of water for dilution. The signs and symptoms that may result from an emergency or an unexpected acute overexposure include: nausea; vomiting; gastritis.

Cardiovascular

The signs and symptoms that may result from an emergency or an unexpected acute overexposure include: arrhythmia.

Central Nervous system

Monitor for shock; anticipate seizures and treat accordingly.

Medical Conditions Aggravated by Exposure to this Material

Provide general supportive measures and treat symptomatically. Please consider other resources such as a regional Poison Control Center or web sites like the National Library of Medicine TOXNET @ http://toxnet.nlm.nih.gov. A specific antidote is not known. Some of the symptoms presented may become life threatening if the exposure is a result of an emergency or an unexpected acute overexposure. Additionally, some workers with certain pre-existing medical conditions such as: asthma, allergies, or impaired pulmonary and/or liver functions, or who may be particularly susceptible to this material, may be affected by exposure to this material.

Sensitivity to Static Discharge

Material can accumulate static charges from material handling management. Bond and ground as appropriate while recognizing that bonding and grounding alone may be insufficient to eliminate the potential hazard from static-accumulating flammable liquids. For additional recommendations, consult an applicable guideline such as National Fire Protection Association [NFPA] 77, “Recommended Practices on Static Electricity” and API RP “Recommended Practice 2003, Protection Against Ignitions Arising out of Static, Lightning, and Stray Currents” (2008).  The Minimum Ignition Energy for some organic solids as a dust may be as low as 3 mJ [millijoules]. The minimum Explosive Concentration for some organic solids as a dust may be as low as 0.025 oz/ft3 or ~20g/m3.

Suitable Extinguishing Media

Dry chemical, foam, carbon dioxide, water fog.

Extinguishing Media which must not be used for Safety Reasons

Do not use a solid water stream as it may scatter and spread fire.

Protection of Firefighters/Specific Hazards Arising from the Chemical

Exclude air; treat like a gasoline or oil fire. Wear full protective clothing, including helmet, self-contained positive pressure or pressure demand breathing apparatus, protective clothing and face mask.

Accidental release measures

Personal Precautions

Follow facility/company’s emergency plans.

Environmental Precautions

Stop the flow of material, if this is without risk. Eliminate sources of ignition. Ventilate contaminated area. Material will be HOT when in liquid state. One may consider allowing the material to cool as part of a response plan. Contain the spill and prevent the material from obtaining access to any confined spaces, public sewers, or waterways.

Methods for Clean-Up

Ventilate the contaminated area. Eliminate ignition sources including sources of electrical, static or frictional sparks. Material will be HOT when in liquid state.  Be sure any absorbents used can withstand the temperature. One may wish to allow it to cool before attempting to collect the material using absorbents, non-sparking tools, explosion-proof vacuums or other equipment required by the size of the release. When material is cool, manage the release as a solid. For example, one can: collect solids, place them into an appropriate container, properly label the container, and then close the container. Immediately arrange for the containers to be palced in an appropriate waste handling area for ultimate transportation or disposal. Thoroughly clean the release area with a suitable agent and collect any cleaning, rinsing media(s) for proper reclamation or disposal. Wear appropriate personal protective equipment during cleanup activities.

Other Information

Wear appropriate protective equipment and clothing during clean-up. Determine appropriate course of action for the collected material. Regulations vary. Consult local authorities before disposal.

Exposure Guidelines

All PPE use is to be determined by a qualified person.

Handling and storage

Handling

Guard against dust accumulation of this material. As with all chemicals, good industrial hygiene practices should be followed when handling this material. When the container(s) is empty it may retain product residue including vapors which could accumulate. Therefore, do not cut, drill, grind, or weld empty containers. Additionally, do not conduct such activity(ies) near full, partially full, or empty product containers without appropriate workplace safety authorization(s) or permit(s).

Storage

Protect container from physical abuse. Keep the container tightly closed. Store in a cool, dry, well-ventilated storage area. Keep separate from incompatibles. Bond and ground containers when transferring material. Empty product containers may contain product residue. Do not reuse empty containers.
