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.

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: 7/26/00 CHLOROTRIS (TRIPHENYLPHOSPHINE) RHODIUM (I) MSDS No. C3025
Flash Point: Not applicable
Autoignition Temperature: Not applicable
LEL: Not Applicable
UEL: Not Applicable
Extinguishing Media: Water, foam, CO2, dry chemical. Use extinguishing media appropriate for surrounding fire conditions.
Unusual Fire or Explosion Hazards:
Hazardous Combustion Products: Not applicable
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: Prevent wastage; conserve, accumulate spent residues wipes, ect. in inert containers; polyethylene or
polypropylene is suitable for recovery of precious metal. Wear protective clothing and respiratory
protection.
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:
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.

Section 11- Toxicological Information
Toxicity Data:
Animal tests suggest that this compound is mildly irritating to skin and eyes. Oral LD50 >500 mg/kg (rat) is not classified as
harmful by ingestion. Some Rhodium compounds may cause mild skin and eye irritaion. Signs and symptoms of irritaion are
itching, redness and swelling, and in severw cases, burning and pain at the site of exposure. Irritaion should stop when exposure is
dicontinued and first aid procedures are followed. There are no documented effects of overexposure to Rhodium metal.
