2 ACUTE OR IMMEDIATE EFFECTS : ROUTES OF ENTRY AND SYMPTOMS INGESTION Not a probable route of exposure SKIN Prolonged contact may product skin irritation. Avoid skin contact EYE Mechanical irritation INHALATION Toxic and corrosive hydrogen fluoride may be liberated during processing above 200 C (392 F), or from smoking tobacco or cigarettes contaminated with resin dust. Lung effects may be delayed for several hours. During vulcanization small amounts of methyl bromide may be formed and liberated as a gas. CHRONIC EFFECTS None known MEDICAL CONDITIONS AGGRAVATED TY EXPOSURE None known CARBON BLACK : CAS # 133-86-4 Immediate effects of overexposure to Carbon Black by inhalation may include irritation of the nose, throat, and lungs with cough, difficulty breathing or shortness of breath. If particles from Carbon Black contact the eye, mechanical irritation with tearing, pain or blurred vision may result. Significant skin permeation, and systemic toxicity, after contact with Carbon Black appears unlikely. There are no reports of human sensitization. Epidemiologic studies demonstrate not significant risk of human cancer from exposure to Carbon Black. While some reports cite an increased incidence of pulmonary abnormalities, such as, (decreased pulmonary function and radiological changes) among Carbon Black workers, other reports show no correlation between exposure and effects on pulmonary function or disease. Increased susceptibility to the effects of Carbon Black may be observed in persons with pre-existing disease of the lungs. METHYL ETHYL KETONE : CAS # 78-93-3 Skin contact with liquid Methyl Ethyl Ketone may cause dermatitis with itching or rash. Repeated and / or prolonged exposure may cause defatting of the skin with itching, redness or rash. There are inconclusive or unverified reports of human sensitization. Eye contact with liquid Methyl Ethyl Ketone may cause eye irritation with tearing, pain or blurred vision. Contact with the vapor or aerosol may cause eye irritation with tearing, pain, or blurred vision. Short-term inhalation exposure to Methyl Ethyl Ketone may cause non-specific effects such as headache, nausea, and weakness. Gross overexposure may cause central nervous system depression with dizziness, confusion, incoordination, drowsiness or unconsciousness. Simultaneous exposure to Methyl Ethyl Ketone and chemicals known to produce neuropathy may enhance the neuropathic effect of these chemicals. Increased susceptibility to the effects of Methyl Ethyl Ketone may be observed in persons with pre-existing disease of the central nervous system.

3 Carcinogenicity Information None of the components present in this material at concentrations equal to or greater that 0.1% are listed by IARC, NTP, OSHA, or ACGIH, as a carcinogen. FIRST MEASURES AID First Aid INHALATION

ACCIDENTAL RELEASE MEASURES Safeguards (Personnel)

Note: Review FIRE FIGHTING MEASURES AND HANDLING (PERSONNEL) sections before proceeding with clean-up. Use appropriate PERSONAL PROTECTIVE EQUIPTMEN during clean-up.

Initial Containment Dissipate vapor with water spray. Prevent material from entering sewers, waterways, or

low areas. Spill Clean Up

All flushing and clean-up residuals should be collected for proper disposal to prevent soil and surface, ground and sewer water contamination Discarded material is a RCRA hazardous waste.

HANDLING AND STORAGE Handling (Personnel)

Avoid breathing vapors or mist. Avoid contact with eyes, skin, or clothing. Wash thoroughly after handling. Wash clothing after use.

Handling (Physical Aspects)

Keep away form heat, sparks and flames. Open container only in well-ventilated area. Close container after each use.

Storage Store in a well ventilated place. Store in a cool place EXPOSURE CONTROLS / PERSONAL PROTECTION Engineering Controls Keep container tightly closed.

Use ventilation that is adequate to keep employee exposure to airborne concentrations below the permissible exposure limits, for methyl ethyl ketone (PEL,200 ppm); hydrogen fluoride (PEL,3 ppm) and methyl bromide (PEL, 5 ppm).

Personal Protective Equipment EYE / FACE PROTECTION

Wear safety glasses. Wear coverall chemical splash goggles when possibility exists for eye and face contact due to splashing or spraying material. ANIOSH / MSHA approved air purifying respirator with an organic vapor cartridge or canister may be permissible under certain limited circumstances where airborne concentrations are expected to exceed exposure limits. Protection provided by air purifying respirators is limited. Use a positive pressure air supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstances where air purifying respirators may not provide adequate protection.

PROTECTIVE CLOTHING Wear impervious clothing, such as gloves, apron, boots or whole bodysuit made from butyl Rubber, or Neoprene as appropriate. Do not touch decomposed parts even when cool.

Incompatibility with Other Materials

Viton Caulk and Coating (THD, & THP) (defined under page 1 under components / material) is incompatible with caustic, amines, alkanolamines, aldehydes, ammonia, strong oxidizing agents, chloroform, chlorosulfonic acid, oleum, hydrogen peroxide, alkali metals, halogens, rubber, plastics, strong bases, mineral acids, and finely divided metals such as aluminum. Once the caulk or coating has bee applied, the methyl ethyl ketone removed and the product has been vulcanized, the nature and extent of the product’s compatibility changes. The product is now compatible with rubber and plastics. Furthermore, the extent of compatibility with caustics, mineral acids, (sulfuric, hydrochloric, nitric, etc) and strong bases becomes a function of variables such as : concentration, temperature, and contaminants in the media. It is advised that on discuss specific compatibility issues, related to end-use conditions, with the supplier and conduct appropriate compatibility evaluations.

Decomposition

HAZARDOUS DECOMPOSITION PRODUCT Hydrogen fluoride (HF), carbon monoxide and perfluoroolefins. The OSHA permissible exposure limit is 3 ppm for HF. If Viton caulk and coating used at temperature >316 deg C (600 F), the surface of the parts may contain HF or HF condensate, which may cause severe burns, sometimes with symptoms delayed for several hours. Wear Neoprene or PVC (if temperature is low enough) gloves when handling parts or equipment after exposure to such high temperatures. If condensate is expected, wash equipment and parts well with lime water (calcium hydroxide solution). Discard gloves after handling degraded Viton parts.

Polymerization Polymerization will not occur. TOXICOLOGICAL INFORMATION # Animal Data See Hazards Identification section for potential health effects. CARBON BLACK Oral ALD, rat: > 25, 100 mg / kg

Repeated inhalation exposure of animals to Carbon Black cause inflammation of the respiratory track, lungs and emphysema. Repeated exposure to high doses of Carbon Black by ingestion or skin contact caused no significant toxicological effects. No adequate studies have been conducted in animals to define the carcinogenicity of Carbon Black by ingestion. In several skin painting studies using various Carbon Blacks no carcinogenicity was observed. Tests by inhalation for carcinogenicity in rats show significant increases in lung tumors in female rats but not male rats. In another study using female mice exposed by inhalation to Carbon Black there was no increase in the incidence of respiratory tract tumors. Researchers conducting their rat inhalation studies believe that these effects probably result form the massive accumulation of small dust particles in the lung, which overwhelm the normal lung clearance mechanisms. This represents “lung overload” phenomenon, rather that specific chemical effect of the dust particle in the lung. Tests have shown that this material does not cause genetic damage in bacterial or mammalian cell cultures. Tests in animals for genetic toxicity have produced mostly negative results. No animal data are available to define developmental or reproductive toxicity.

METHYL ETHYL KETONE Methyl Ethyl ketone Oral LD50, rat : 2,700 mg / kg Dermal LD50, rabbit : 10,200 mg / kg Inhalation 4 hours, ALC, rat : 2,000 ppm

Animal testing indicates that Methyl Ethyl Ketone is a mild skin irritant, and an eye irritant, but has not been tested for skin sensitization. Single ingestion exposure with Methyl Ethyl Ketone caused liver effects. Single exposure to high doses caused narcosis. Long-term dermal exposure to Methyl Ethyl Ketone caused peeling of the skin.

7

Single inhalation exposure to Methyl Ethyl Ketone caused irritation of the eyes, upper respiratory tract irritation, and cardiovascular system changes. Single exposure to high concentrations caused narcosis. Repeated exposure caused increased liver weight, and altered enzyme activity. Inhalation or ingestion of Methyl Ethyl Ketone alone does not produce neuropathy but it does enhance the neuropathic effects of Ethyl n-Butyl Ketone, Methyl n-Butyl Ketone, Hexane and 2, 5-Hexanedione. No animal data are available to define the carcinogenicity, or reproductive toxicity of Methyl Ethyl Ketone. Animal data show developmental effects only at exposure levels producing other toxic effects in the adult animal. Tests have shown that Methyl Ethyl Ketone does not cause genetic damage in bacterial or mammalian cell cultures, or in animals. Methyl Ethyl Ketone has not been tested for its ability to cause permanent genetic damage in reproductive cells of mammals (not tested for heritable genetic damage).
