Potential Health Effects 2
H
Primary Entry Routes: Dermal F 0
Target Organs: pancreas, liver, thyroid and eyes. R 0
Acute Effects
Inhalation: Vapors, which are not significant unless heated or sprayed can cause irritation to
respiratory tract.
Eye: May cause irritation, redness, tearing.
Skin: Contact will cause irritation and reddening swelling.
Ingestion: Effects are unknown.
Carcinogenicity: IARC, NTP, and OSHA do not list any components of this product as a
carcinogen.
Medical Conditions Aggravated by Long-Term Exposure: Pre-existing skin disorders.
Chronic Effects of Overexposure:
This product contains an organo-mercury catalyst below the reportable level required by OSHA
1910.1200; however, due to the chronic toxicity of organo-mercury compounds careful handling of
this product is required.
Section 4 - First Aid Measures
Inhalation: Remove source(s) of contamination and move victim to fresh air.
Eye Contact: Flush eyes with plenty of water. If irritation persists, seek medical attention.
Skin Contact: In case of skin contact, wash thoroughly with soap and water; remove contaminated
clothing and launder before reuse; seek medical attention if rash develops.
Ingestion: Do not induce vomiting unless instructed by a physician. Contact physician
immediately
After first aid, get appropriate in-plant, paramedic, or community medical support.

Section 5 - Fire-Fighting Measures
NFPA
Flash Point: >300 掳F (150掳C)
Flash Point Method: COC 0
0
2
Flammability Classification: Non-Flammable 鈥?
Extinguishing Media: Water Fog, Dry Chemical, and Carbon Dioxide Foam
Unusual Fire or Explosion Hazards: None
Fire-Fighting Instructions: Fire fighters should wear self-contained breathing apparatus. Do not
release runoff from fire control methods to sewers or waterways.
Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear
a self-contained breathing apparatus (SCBA) with a full facepiece operated in pressure-demand or
positive-pressure mode.
Section 6 - Accidental Release Measures
Spill /Leak Procedures: Dike and contain spill; absorb or scrape up excess into suitable container
for disposal. Stop or reduce discharge if it can be done safely.
Regulatory Requirements: Follow applicable OSHA regulations (29 CFR 1910.120).
Section 7 - Handling and Storage
Handling Precautions: Minimize breathing of vapors and avoid prolonged or repeated contact
with skin. Wear proper protective equipment. If ventilation is not sufficient, wear proper
respiratory equipment. Use good general housekeeping procedures.
Storage Requirements: Store in cool dry, well-ventilated area.
Section 8 - Exposure Controls / Personal Protection
Engineering Controls:
Ventilation: 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: Seek professional advice prior to respirator selection and use. Follow
OSHA respirator regulations (29 CFR 1910.134) and, if necessary, wear an MSHA/NIOSH-
approved respirator. 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 nonroutine 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: Wear chemically protective gloves, boots, and aprons to prevent
prolonged or repeated skin contact. Wear protective eyeglasses or chemical safety goggles, per
OSHA eye- and face-protection regulations (29 CFR 1910.133). Contact lenses are not eye
protective devices. Appropriate eye protection must be worn instead of, or in conjunction with
contact lenses.
Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using
this material, especially before eating, drinking, smoking, using the toilet, or applying cosmetics
