HARMFUL OR FATAL IF SWALLOWED

HARMFUL IF ABSORBED THROUGH SKIN

GRINDING MAY PRODUCE FLAMMABLE DUST/AIR MIXTURES

MOLTEN PRODUCT CAN CAUSE THERMAL BURNS

MAY CAUSE ALLERGIC SKIN AND RESPIRATORY (ASTHMA LIKE) REACTION

HMIS Hazard Ratings Health - 3, Flammability - 1, Chemical Reactivity - 1

4. FIRST AID MEASURES

Ingestion:

Do not induce vomiting. Have a conscious person drink several glasses of water or

milk. Seek immediate medical attention.

Inhalation:

Allow the victim to rest in a well ventilated area. Seek immediate medical attention.

Skin Contact:

After contact with skin, wash immediately with plenty of water. If irritation persists

seek medical attention. Wash contaminated clothing before reusing.

Eyes:

Immediately flush with water for at least 15 minutes, keeping eyelids open. Seek

medical attention.

5. FIRE FIGHTING MEASURES

Small fire: Carbon dioxide, water, foam.

Large fire: Water spray, fog or foam, do not use water jet.

Extinguishing Media:

DO NOT USE DRY CHEMICAL: Large volumes of gases could be produced by

reaction with Maleic Anhydride.

Special Fire-Fighting Procedures:

Wear self-contained breathing apparatus with full face piece operated in the

positive pressure demand mode and full body protection when fighting fires

Hazardous Combustion Products:

Carbon Dioxide, Carbon Monoxide.

Unusual Fire and Explosion Hazards:

Unstable, or air-reactive or water-reactive chemical involved (see Section 10).

Vapors from melted material can be ignited. Keep melted material away from

ignition sources. May form flammable dust-air mixtures when finely divided.

Prevent dust buildup by providing adequate ventilation during grinding or milling

operations.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions:

Avoid breathing dust. Pressure demand air supplied respirators should always be

worn when the airborne concentration of the contaminant or oxygen is unknown.

Otherwise, wear respiratory protection and other personal protective equipment as

appropriate for the potential exposure hazard. Wear gloves, goggles, and

protective clothing to avoid contact with eyes, skin, or clothing.Bartek Ingredients Inc. 421 Seaman St., Stoney Creek, Ont. Canada L8E 3J4 905-643-1286 English MSDS: Maleic Anhydride Dec 05

IN CASE OF A DANGEROUS GOODS EMERGENCY CALL CANUTEC AT THE 24-HOUR NUMBER 613-996-6666

Personal precautions cont’d:

Recycle, if possible. Use appropriate tools to put the spilled solid in a waste

disposal container.

If necessary, neutralize the residue with a dilute solution of sodium hydroxide. Do

not dry sweep or use methods that increase dusting. Prevent entry into sewers

and waterways.

7. HANDLING AND STORAGE

Handling:

Eye wash and safety shower should be available nearby when this product is

handled or used.

Minimum feasible handling temperatures should be maintained. Avoid generating

mist or dust.

Exercise care when opening bleeders and sampling ports.

Do not breathe gas, fumes, vapor or spray. Do not ingest. Avoid contact with skin

and eyes. After handling, always wash hands thoroughly with soap and water.

Storage:

Store away from incompatible materials. Store at temperatures not exceeding

70°C (158°F). Contains moisture sensitive material -- store in a dry place.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Eye/Face Protection

Avoid eye contact. Chemical type goggles with face shield must be worn. Do not

wear contact lenses.

Skin Protection

Protective clothing such as coveralls or lab coats must be worn. Gloves resistant

to chemicals and petroleum distillates required. When handling large quantities,

impervious suits, gloves, and rubber boots must be worn. Remove and dry-clean

or launder clothing soaked or spoiled with this material before reuse. Dry cleaning

of contaminated clothing may be more effective than normal laundering. Inform

individuals responsible for cleaning of potential hazards associated with handling

contaminated clothing.

Respiratory Protection

Airborne concentrations should be kept to the lowest levels possible. If vapor, mist

or dust is generated and the occupational exposure limit of the product is

exceeded, use appropriate NIOSH or MSHA approved air purifying or air supplied

respirator after determining the airborne concentration of the contaminant. Air

supplied respirators should always be worn when airborne concentration of the

contaminant or oxygen content is unknown.

Ventilation

Adequate to meet occupational exposure limits (see below)

Exposure Limits

TLV-TWA: 0.1 ppm 8 hours (ACGIH TLV, United States, 2002)

10. STABILITY & 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 (see Incompatible Materials, above).

11. TOXICOLOGICAL INFORMATION

Oral LD-50 (rat)

1030 mg/kg

Dermal LD-50 (rabbit)

2620 mg/kg

Skin irritation (rabbit)

corrosive

Eye irritation (rabbit)

extremely irritating

Sensitization

The limited number of animal studies investigating the dermal or respiratory

sensitization potential of maleic anhydride have not shown conclusive evidence of

sensitization potential. Although there have been reports of human dermal or

respiratory sensitization from maleic anhydride exposures, the number of reports

has been low when compared to the number of potentially exposed individuals.

Maleic anhydride has a low potential for human dermal or respiratory sensitization.

Effects of Acute Exposure

Extremely dangerous in case of skin contact (corrosive, irritant), of eye contact

(irritant) and inhalation. Very dangerous in case of ingestion. Slightly dangerous in

case of skin contact (sensitizer). Eye contact can result in corneal damage or

blindness. Inhalation of dust will produce irritation to gastro-intestinal or respiratory

tract, characterized by burning, sneezing and coughing.

Effects of Chronic Exposure:

Carcinogenic effects Not available. Mutagenic effects: Not available. Teratogenic

Effects: Not available. Toxicity of the product to the Reproductive system: Not

available. Repeated exposure of the eyes to low level dust can produce irritation.

Repeated skin exposure can cause local skin destruction or dermatitis. Repeated

inhalation can cause a varying degree of respiratory irritation or lung damage.

Repeated exposure to a highly toxic material may produce general deterioration of

health by accumulation in one or many human organs

12. ECOLOGICAL INFORMATION

Aquatic Toxicity

LC50 - 96hr 230 mg/liter (mosquito fish) practically nontoxic

LC50 - 24hr 150 mg/liter (blue gill sunfish) practically nontoxic

Mobility

This product is not likely to volatilize rapidly into the air because of its low vapor

pressure.

Bioaccumulative potential

This product is not expected to bioaccumulate through food chains in the

environment.

Remarks

This product will hydrolyze rapidly to the acid. Expected to be slightly toxic to

aquatic species because of acidity.

13. DISPOSAL CONSIDERATIONS
