First-aid measures
Eye Contact:
Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes,
keeping eyelids open. Cold water may be used. Do not use an eye ointment. Seek medical attention.
Skin Contact:
If the chemical got onto the clothed portion of the body, remove the contaminated clothes as quickly as possible,
protecting your own hands and body. Place the victim under a deluge shower. If the chemical got on the victim's
exposed skin, such as the hands : Gently and thoroughly wash the contaminated skin with running water and
non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. Cold water may be used.
If irritation persists, seek medical attention. Wash contaminated clothing before reusing.
Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate
medical attention.
Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate medical attention.
Serious Inhalation:
Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
resuscitation. WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth resuscitation
when the inhaled material is toxic, infectious or corrosive. Seek immediate medical attention.
Ingestion:
Do not induce vomiting. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible
indication that the toxic material was ingested; the absence of such signs, however, is not conclusive. Loosen
tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Seek immediate medical attention.
Serious Ingestion: Not available.

Fire-fighting measures
SMALL FIRE: Use DRY chemical powder.
LARGE FIRE: Use water spray, fog or foam. Do not use water jet.
LARGE FIRE: Use water spray, fog or foam. Do not use water jet.
Accidental release measures
Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container.
Large Spill:
Corrosive solid.
Stop leak if without risk. Do not get water inside container. Do not touch spilled material. Use water spray to
reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition
sources. Call for assistance on disposal. Be careful that the product is not present at a concentration level above
TLV. Check TLV on the MSDS and with local authorities.

Handling and storage
Precautions:
Keep container dry. Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire
risk, evaporate the residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not
breathe dust. Never add water to this product Wear suitable protective clothing In case of insufficient ventilation,
wear suitable respiratory equipment If ingested, seek medical advice immediately and show the container or the
label. Avoid contact with skin and eyes Keep away from incompatibles such as oxidizing agents, reducing
agents, acids, moisture.
Storage:
Keep container dry. Keep in a cool place. Ground all equipment containing material. Corrosive materials should
be stored in a separate safety storage cabinet or room.

Exposure controls / personal protection
Engineering Controls:
Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.
Personal Protection:
Splash goggles. Synthetic apron. Vapor and dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves.
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Vapor and dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.
Exposure Limits:
TWA: 0.25 (ppm) from ACGIH (TLV)
TWA: 1 (mg/m3) from ACGIH
Consult local authorities for acceptable exposure limits.

Stability and reactivity
Chemical Stability The product is stable except when in contact with water
Conditions to Avoid Incompatible materials, moisture
Incompatible materials May react violently with amines, alkali metal ions such as Sodium or Potassium, and bases. At temperatures above 150°C, these materials, at concentrations as low as 200 ppm., can trigger a rapid decomposition and polymerization reaction that would produce heat and gas and cause equipment to rupture.
Hazardous Decomposition Products Toxic levels of Carbon monoxide, carbon dioxide, irritating aldehydes and ketones may be formed on burning. Heating in air may produce irritating aldehydes, acids, and ketones.
Hazardous Polymerization Will not self-polymerize but can undergo uncontrolled co-polymerization in the presence of other monomers and catalysts.

Disposal considerations
Recycle if possible. Consult your local authorities. This product has the RCRA characteristics of corrosivity, and is identified under RCRA as Maleic Anhydride. If discarded in its present form, it would have the hazardous waste numbers D002 and U147. Under RCRA, it is the responsibility of the user of the product to determine, at the time of disposal, whether the product meets RCRA criteria for hazardous waste.
