Aro clor 1242 - 1 . 0 mg per cubic meter o f air. (0. 50 action leve 1) b. Aro clor 1254 - 0 . 5 mg per cubic meter o f air. (0. 25 action leve 1) 2 Haz ar ds and Cont rol a. Inhalation: Absorption is chiefly by inhalation. Concentrations in the workroom atmosphere should be maintained below the recommended levels. Where the chlorinated diphenyls are used at room tempera tures, the hazard of inhalation is considered slight or absent. When these materials are subjected to elevated temperatures, the process either should be completely enclosed or other adequate mechanical exhaust ventilation must be provided to reduce con centrations to safe levels. b. Skin contact: Operations and handling procedures should be such as to avoid the possibility of pro longed or repeated skin contact. Contaminated clothing must be laundered before reuse. c. Eye contact: Goggles or face shield should be used where there is a possibility of liquid splashes. 3. Emergency Treatment: Skin surfaces exposed' to chlorodiphenyls should be thoroughly washed with soap and water at once. If clothing has been contaminated, it should be removed promptly. If exposure to a high vapor concentration occurs, as in the case of spills at elevated temperatures, the patient should be moved from exposure and kept at rest until seen by a physician. Oxygen should be a d m i n i s t e r e if breathing is difficult. Eyes contaminated with chlorodipheny1 should be irrigated with water for at least 15 minutes and the patient should be seen by a physician.

TOXICITY (Cont'd) Special procedures: Persons who are regularly or repeatedly exposed to chlorodiphenyls should be examined periodically to detect early evidence of skin irritation and/or liver damage. Persons with known liver disease should not be exposed to repeated contact with the chlorodiphenyls. * The information in this section is from the Hygienic Guide Series published by the American Industrial Hygiene Association. The particular pamphlet is "Chlorodiphenyls" , Jan.-Feb., 1965. NEV Z479 738134 DEPT. 259 - STANDARD MANUFACTURING PROCESS PYRANOLS AND INERTEENS APPENDIX J - SAFETY AND TOXICITY DATA (Cont'd) III. TOXICITY (Continued) The following toxic rating code will be used in describing the toxicity of these materials: 0 - none .1 -slight 2 - moderate 3 - high U - unknown A. Biphenyl (Code 82601) Threshold Limit Value (TLV for 8 hours) * 0.2 ppm or 1.0 Mg/M^. Action Level = 0.1 ppm or 0.5 Mg/M^. 1. Synonyms: Diphenyl 2. Description: White flakes or solid off-white mass somewhat pleasant odor. 3. Constants: Mol. Wt. 154.2; M.P. 69C; B.P. 255C; Density: .99100 75/4C. 4. FlashPoint: 235F (C.C.) 5. Auto Ignition Temperature: 1004F. 6. Toxic Hazard Rating: Acute Local: U Acute Systematic: Ingestion 3, Inhalation 3 Chronic Local: U 7. Fire Hazard: Definitely when exposed to heat or flame; can react with oxidizing materials. 8. Fire Fighting: CO2 or dry chemical. 9. Formula: C6H5C6H5 10. Biphenyl vapors are irritating to the upper respiratory tract. Workers should not be exposed to vapor levels throughout their shift in excess of the threshold limit value of 1 milligram per cubic meter of air (or about 0.2 ppm). The compound, or organic solu tions of the compound can absorb through the intact skin; therefore, repeated skin contact should be avoided. 11. See Hygienic Guide Series on "Diphenyl".

Description: Greenish yellow gas 2. Formula: Cl 3. Constants: Mol. Wt. 70.914; M.P. = 101C; B.P. 34.5C Density 1.47 @ 0C. 4. Toxic Hazard Rating: Acute Local: Irritant 3; Inhalation 3; Acute Systemic: 0 Chronic Local: U Chronic Systemic: U T.L.V. - 1 ppm in air per 8 hour day. 0.5 ppm action level. 5. Toxicology: Chlorine is extremely irritating to the mucous membranes of the eyes and respiratory tract. It combines with moisture to liberate nascent oxygen and from hydrochloric acid. Both these substances, if present in quantity, cause inflammation of the tissues with which they come in contact. If the lung tissues are attacked, pulmonary edema may result. A concentration of 3.5 ppm produces a detectable odor; 15 PPM causes immediate irritation of the throat. Concentrations of 50 ppm are dangerous for even short exposures. 1000 ppm may be fatal even when the exposure is brief. Because of its intensely irritating properties, severe industrial exposure seldom occurs as the workman is forced to leave the area before he can be seriously affected. In cases where this is impossible, the initial irritation of the eyes and mucous membranes of the nose and throat is followed by cough, a feeling of suffocation and later pain and a feeling of constriction in the chest. If exposure has been severe, pulmonary edema may follow with rales being heard over the chest. 6 Fire Hazard: Moderate -- can react to cause fire or explosion upon contac t with turpn tine , ether, ammonia gas, illumina tin g gas, hydroc arbons, hydrogen and powdered me ta Is .

Explosion Hazard: Present by reaction with reducing agents. 8. Disaster Control: Dangerous; emits highly toxic fumes; will react with water to form toxic and corrosive fumes of HC1; is heavier than air -gas will hug the ground. People without adequate protection should go across wind until out of the affected area. C. HC1 Off-Gas (Code 828.51) 1. Synonyms: Muriatic Acid, Chlorophydric Acid, Hydrogen Chloride 2. Description; Colorless gas. 3. Formula: HC1 4. Toxic Hazard Rating: Acute Local: Irritant 3, Ingestion 3, Inhalation 3 Acute Systemic: U Chronic Local: Irritant 2 Chronic Systemic: U 5. TLV: 5 ppm in air for 8 hour day. Action Level 2 . 5 ppm 6. Toxicology: Hydrogen chloride is an irritant to the mucous membranes of the eyes and respiratory tract. Concentration of 35 ppm causes irritation of the throat after short exposure. Concentrations of 50 to 100 ppm are tolerable for one hour. More serious exposures result in pulmonary edema and often laryngeal spasm. Concentrations of 1000 to 2000 ppm are dangerous even for brief exposures. Mists of HC1 are considered less harmful than the anhydrous form since the droplets have no dehydrating effeet. 7.

TOXICITY (Cont'd) D. Ferric Chloride (Code 33500) T.L.V. of 1.0 Mg/M3 Action Level = 0.5 Mg/M3 1. Description: Granular solid 2. Formula; FeCl3 (Anhydrous) 3. Cons tan ts : Mol. Wt. * 166.22, Melting Pt = sublimes solubility in H2 O = very soluble with heat rise. 4. Toxic Hazard Rating: Acute Local: Irritant 1: Ingestion 1 Acute Systemic: U Chronic Local: Irritant 1 Chronic Systemic: U 5. Fire Hazard: There is no fire hazard under normal conditions, but it will emit toxic fumes at high temperatures. 6. Handling: Protect the skin with approved protective clothing, avoid the breathing of FeCl3 dust, wear approved respirator with adequate cartridge, and protect the eyes with approved goggles. There a r e no storage regulations; however, it should be stored in a dry place as heat is released upon solution in water and dry ferric chloride will not catalyze the chlorination reaction. E. Lime (Code 38800)(Calcium Oxide) T.L.V. 10 Mg/M3 Nuisance Dust 1. Description: Fine white or slightly gray p o w d e r . 2. Formula: CaO 3. Toxic Hazard Rating: Acute Local: Irritant 3; Ingestion 1, Inhalation Acute Systemic: Ingestion 2; Inhalation 3; Skin Absorption 0. Chronic Local: Irritant 3; Inhalation 3 Chronic Systemic: Ingestion 2; Inhalation 2; Skin Absorption 0. 738138 DEPARTMENT 259 - STANDARD MANUFACTURING PROCESS PYRANOLS AND INERTEENS APPENDIX J - SAFETY AND TOXICITY DATA III. TOXICITY E. Lime (Continued) 4. Toxicology: Has a caustic reaction and, therefore, is irritating to the skin. As a dust it can cause dermatitis and irritation of the eyes and mucous membranes. It is a general nuisance type of dust. 5. Fire Hazard: None 6. Explosion Hazard: Virtually none. 7. Handling: Dust respirator, adequate protective clothing, including rubber coated gloves, optional rubber full cover apron and full cover plastic goggles should be used when handling lime (dust). Adequate ventilation and dust removal equipment should be used in the handling area. Lime is added to the stills to neutralize any liberated HC1 and prevent sublimation of the FeCl3 catalyst. It is handled in 50# bags. F. Nitrogen (Code 43101) TLV * Simple asphyxiants. Oxygen content of air must be 18% or higher (equivalent to a partial pressure of 135 mm Hg.) 1. Description: Colorless gas. 2. Formula: N? 3. Constants: Mol. Wt. 28.02; M.P. - 210C; B.P. - 195.8C; Density 1.2506 gr/liter at 0C. 4. Toxicity: None. In high concentrations, it is an asphyxiant.
