Section 3 - Hazards Identification
Emergency Overview
Potential Health Effects
Primary Entry Routes: Inhalation
Target Organs: Not known
Acute Effects Not known
Inhalation: Not known
Eye: Not known
Skin: Not known
Ingestion: Not known
Carcinogenicity: Not known
Medical Conditions Aggravated by Long-Term Exposure: Allergies, lung disease
Chronic Effects: Not known
Other: Respiratory irritation on high exposure, pulmonary effects. Can cause eye irritation. There are no documented effects of
overexposure to this compound, however, intravenous administration of Palladium can cause systemic damage. In
laboratory, Palladium appears to bind to many cell components; it blocks the action of enzymes and interferes with the use
of energy by nerves and muscles; induces lung malfunction and production abnormal fetuses. There are no documented
effects of overexposure in humans
Section 4 - First Aid Measures
Inhalation: Remove person to fresh air. If breathing has stopped, administer artificial respiration. If breathing is difficult,
give oxygen. Get immediate medical attention.
Eye Contact: Flush with plenty of water for at least 15 minutes including beneath eyelids. Remove contacts/glasses while
flushing. Get immediate medical attention.
Skin Contact: Flush with copious amounts of soap and water for at least 15 minutes while removing contaminated clothing and
shoes. Get immediate medical attention. Wash clothing/shoes thoroughly before reuse.

revision: 7/17/01 1% - 10% PALLADIUM ON BARIUM SULFATE MSDS No. PdBaSO4
Ingestion: Do not induce vomiting. Rinse the mouth out with water. Give milk or water. Do not make an unconscious
person vomit. Get immediate medical attention.
Section 5 - Fire-Fighting Measures
Flash Point: Non -volatile
Autoignition Temperature: Not applicable
LEL: Not Applicable
UEL: Not Applicable
Extinguishing Media: Dry chemical, Carbon dioxide, nitrogen, water.
Unusual Fire or Explosion Hazards: Hazardous Combustion Products: This material is not classified as a flammable, but if
involved in a fire, will burn with the possible production of toxic carbon monoxide. The residue, ash, or char will have catalytic
properties and will promote the ignition of flammable liquids and vapors. Dust may form flammable or explosive mixtures with
air. There is a potential for fire and explosion when palladium dust is exposed to heat or flame.. Explosion Hazard from dust
when in contact with heat, flame, (NH4NO3 + heat), (NH/ClO4 @ 240 C), bromates, Ca (OCl)2, chlorates, Cl2, (Cl2 + Cr (OCl)2),
C10, F2, Iodates, IO5, Pd(NO3)2, HgNO3, (oils + air), (K + air), Na2(5)3, ZnO3)2 To help avoid dust explosions, prevent dust
formation. After use, all catalyst which contains absorbed hydrogen may ignite when dried in air, especially in the presence of
organic materials. A used, filtered catalyst should, therefore, be kept wet and out of contact with combustible vapors and liquids.
Palladium dust is a fire and explosion hazard.
Fire-Fighting Instructions: Do not release runoff from fire control methods to sewers or waterways.
Fire-Fighting Equipment: Use normal procedures which include wearing NIOSH/MSHA approved pressure demand self-
contained breathing apparatus, flame and chemical resistant clothing; hat (hard), boots and gloves.
Section 6 - Accidental Release Measures
Spill /Leak Procedures: Remove or eliminate all sources of flammable liquids or vapors. Collect all spillage. Wash with water
to reduce its organic content and store in water wetted condition in a sealed container; high efficiency
vacuum recommended. Collect residue wipes, ect. for recovery of precious metal. Wear protective
clothing ect.
Containment: For large spills, dike far ahead of liquid spill for later disposal. Do not release into sewers or waterways.
Regulatory Requirements: Follow applicable federal, state and local regulations.
Section 7 - Handling and Storage
Handling Precautions: Follow good industrial hygiene and housekeeping practices. Do not eat, drink, or smoke while working
with this material. Wash hands before eating, drinking, smoking or applying cosmetics and at the end of
the work shift. Do not breath dust or mist and do not get in eyes, on skin or on clothing. A shower and
clothing policy should be established depending on the potential for exposure.
Storage Requirements: Keep in a cool, dry, well ventilated place away from incompatible materials and conditions. Use proper
labeling in accordance with 29 CFR 1910.1200.
Section 8 - Exposure Controls / Personal Protection
Engineering Controls:
Ventilation:
Local Exhaust: Fume Hood at point of generation.
Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs
(Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area
by controlling it at its source.
Administrative Controls:
Respiratory Protection: If there is a possibility that the TLV鈥檚 or PEL鈥檚 may be exceeded, a NIOSH/MSHA approved full
face piece respirator with high efficiency particulate filter cartridge is the recommended minimum
level of respiratory protection. To ensure proper respirator selection and use, refer to the
requirements of 29 CFR 1910.134 and the latest edition of ANSI Z 88.2.
Select respirator based on its suitability to provide adequate worker protection for given working
conditions, level of airborne contamination, and presence of sufficient oxygen. For emergency or non-
routine operations (cleaning spills, reactor vessels, or storage tanks), wear an SCBA. Warning! Air-
purifying respirators do not protect workers in oxygen-deficient atmospheres. If respirators are used,
OSHA requires a written respiratory protection program that includes at least: medical certification,
training, fit-testing, periodic environmental monitoring, maintenance, inspection, cleaning, and
convenient, sanitary storage areas.
Protective Clothing/Equipment:

revision: 7/17/01 1% - 10% PALLADIUM ON BARIUM SULFATE MSDS No. PdBaSO4
Protective Gloves: Rubber, impervious gloves to chemicals and conditions encountered.
Eye Protection: OSHA, ANSI approved safety goggles/glasses. Contact lenses are not protective devices. Appropriate
eye- and face-protection must be worn instead of, or in conjunction with, contact lenses.
Protective Clothing: Wear disposable protective clothing to prevent exposure. Protective clothing includes lab coat and
apron, flame and chemical resistant coveralls, and boots/safety shoes to prevent prolonged or repeated
skin contact.
Safety Stations: Where there is a possibility that an employee鈥檚 eyes may be exposed to the product, an eyewash fountain
should be provided within the immediate work area for emergency use. Safety drench shower and
hygienic facilities are available in production areas.
Comments: Follow good industrial hygiene and housekeeping practices. Do not eat, drink, or smoke while working
with this material. Wash hands before eating, drinking, smoking or applying cosmetics and at the end of
the work shift. Do not breathe dust or mist and do not get in eyes, on skin or on clothing. A shower
and clothing policy should be established depending on the potential for exposure.
This material will catalyse the oxidation of combustible organic vapors in the presence of oxygen or air.
The risk of ignition can be reduced by cooling both the catalyst and the solvent before mixing and performing the mixing under
the inert atmosphere such as nitrogen, or by removing oxygen from the system to eliminate the ignition potential. Since many
catalysts are pyrophoric after use in hydrogenation reaction, they should, ideally, be filtered under an inert atmosphere. If this is
not possible, then the filtered solid should not be allowed to dry to such that air is drawn through it before it was washed with
water in sealed containers while awaiting metal recovery. Use proper warning labels in accordance with 29 CFR 1910.1200.
