D&J Chemicals Co., Ltd.
CAUSE IRRITATION AND/OR ALLERGIC REACTION IN THE
RESPIRATORY TRACT. MELTED MATERIAL CAUSES THERMAL
BURNS. MAY BE HARMFUL IF SWALLOWED.
Potential Health Effects
Inhalation:
Inhalation of dust or vapor may cause irritation of the nose and throat.
Coughing, sneezing, and burning of the throat may be experienced. Can cause
allergic respiratory reactions.
Ingestion:
Corrosive. Toxic. Swallowing can cause sore throat, abdominal pain, and
vomiting. May cause burns to the digestive tract.
Skin Contact:
Corrosive. May not cause immediate burning of the skin, but prolonged contact
with moist skin cause reddening and blistering or burns.
Eye Contact:
Corrosive. Dust or vapor cause burns or irritation of the eyes with swelling.
Sensitivity to light and double vision may occur.
Chronic Exposure:
Repeated inhalation may cause chronic bronchitis of the asthmatic type.
Repeated skin contact may lead to dermatitis or sensitization.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is
difficult, give oxygen. Call a physician.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give
anything by mouth to an unconscious person. Get medical attention.
Skin Contact:
Remove any contaminated clothing. Wash skin with soap or mild detergent and
water for at least 15 minutes. Get medical attention if irritation develops or
persists.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting
lower and upper eyelids occasionally. Get medical attention immediately.

5. Fire Fighting Measures
Fire:
Flash point: 102C (216F) CC
Autoignition temperature: 477C (891F)
Flammable limits in air % by volume:
lel: 1.4; uel: 7.1
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits
noted above.
Fire Extinguishing Media:
Alcohol foam, carbon dioxide. DO NOT USE dry chemical, multipurpose dry
chemical, or loaded stream media because of explosion potential due to
reactivity of basic compounds in these extinguishing media.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated in the pressure
demand or other positive pressure mode.
6. Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate
personal protective equipment as specified in Section 8. Spills: Clean up spills
in a manner that does not disperse dust into the air. Use non-sparking tools and
equipment. Reduce airborne dust and prevent scattering by moistening with
water. Pick up spill for recovery or disposal and place in a closed container.
Evacuate area of all unnecessary personnel. US Regulations (CERCLA)
require reporting spills and releases to soil, water and air in excess of
reportable quantities. The toll free number for the US Coast Guard National
Response Center is (800) 424-8802.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect
against physical damage. Isolate from incompatible substances. Do not reuse
container. Containers of this material may be hazardous when empty since they
retain product residues (dust, solids); observe all warnings and precautions
listed for the product. Avoid dust formation and control ignition sources.
Employ grounding, venting and explosion relief provisions in accord with
D&J Chemicals Co., Ltd.
accepted engineering practices in any process capable of generating dust and/or
static electricity. Empty only into inert or non-flammable atmosphere.
Emptying contents into a non-inert atmosphere where flammable vapors may
be present could cause a flash fire or explosion due to electrostatic discharge.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL): 0.25 ppm, 1 mg/m3 (TWA)
-ACGIH Threshold Limit Value (TLV): 0.1 ppm, (TWA), Sensitizer, A4 - Not
classifiable as a human carcinogen.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne Exposure Limits. Local exhaust ventilation is
generally preferred because it can control the emissions of the contaminant at
its source, preventing dispersion of it into the general work area. Please refer to
the ACGIH document, Industrial Ventilation, A Manual of Recommended
Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, and engineering controls are not feasible, a
full-face piece respirator with an organic vapor cartridge and particulate filter
(NIOSH type N100 filter) may be worn up to 50 times the exposure limit, or
the maximum use concentration specified by the appropriate regulatory agency
or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants,
cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P particulate
filter. For emergencies or instances where the exposure levels are not known,
use a full-face piece positive-pressure, air-supplied respirator. WARNING:
Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres. Where respirators are required, you must have a written program
covering the basic requirements in the OSHA respirator standard. These
include training, fit testing, medical approval, cleaning, maintenance, cartridge
change schedules, etc. See 29CFR1910.134 for details.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron
or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting or splashing
of solutions is possible. Maintain eye wash fountain and quick-drench facilities
in work area.

9. Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage. Readily sublimes. Decomposes
slowly with water forming maleic acid. When dissolved in water it is a strong acid.
Molten product should be stored under 70C (158F)
Hazardous Decomposition Products:
Carbon dioxide and carbon monoxide may form when heated to decomposition.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Incompatible with alkali metals, alkaline earth metals, amines > 66C (150F). Reacts

11. Ecological Information
Environmental Fate:
When released to air, soil and water; maleic anhydride will probably hydrolyze
to maleic acid and be processed as follows. When released into the soil, this
material is expected to leach into groundwater. When released into the soil, this
material is expected to readily biodegrade. When released into water, this
material is expected to readily biodegrade. When released into water, this
material is not expected to evaporate significantly. When released into the air,
this material is expected to exist in the aerosol phase with a short half-life.
When released into the air, this material is not expected to be subject to wet
deposition. When released into the air, this material is expected to be degraded
by reaction with ozone and photochemically produced hydroxyl radicals. This
