TOXICITY The following toxic rating code will be used in describing the toxicity of these materials: 0 -- none 1 - slight 2 - moderate 3 - high - unknown A. Biphenyl (Code 82601) 1. Synonyms: Diphenyl 2 r Description: White flakes or solid off white mass; somewhat pleasant odor. 3. Constants: Mol. Wt. 154.2: M.P. 69C.; B.P. 255C.; Density .9910 0 75/4C. 4. Flash Point: 235 F. (C.C.) 5. Auto Ignition Temperature: 1004F 1 ri . 6. Toxic Hazard Rating: Acute Local:. D V Acute Systematic: Ingestion 3. Inhalation 3 Chromic Local: U 7. Fire Hasard: Definitely when exposed to heat or flame can react with oxidizing materials. .8. Fire Fighting: C02 or dry chemical. 9.

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 solutions of the com pound can absorbe through the intact skin; therefore, repeated skin contact should be avoided. 11. See Hygienic Guide Series on "Diphenyl*1. B. Chlorine (Code 81059) 1. Description : Greenish yellow gas. 2 . Formula : Cl2 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 M.A.C. - 1 PPM in air per 8 hour day 5. Toxicology: Chlorine is extremely irritating to the mucous membraines of the eyes and respiratory tract. It combines with moisture to liberate nascent oxygen and from hydrochloric acid. Both of these substances, if present in quantity, j u j 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 PFM nay be fatal e-von when the exposure is brief. Because of its intensely irritating proper ties', industrial exposure seldom occurs, as the workman i s forced to leave the area before he can be seriously affected. In c n s vh .?re th i~ i ino.

(Cont'd) 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 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 contact with turpentine, ether, ammonia gas, illuminating gas, hydrocarbons, hydrogen and powdered metals. 7. Explosion Hazard: Present by reaction with reducinz 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) i. Synonyms: Muriatic acid, Chlorohydric 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. M.A.C.: 5 ppm in air for 8 hr. day 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 t h r o a t after short exposure. Concentrations of 50 to 100 p p n are tolerable for 1 hour. More serious exposures r e s u l t in pulmonary edema and often larynga.il spasm. C o n . . . tions of 1000 to 2000 ppm are dangerous even for b r i e ; exposures. Mists of HC1 are considered less harmful ti;an they anhydrous form since the droplets have no dchy1; ..* ir. effect. 7. S H y g i e n i c Cv.ide Suri'C:;. or yd r .*n C h 1 -rid " .

Formula: FeCl3 (Anhydrous) 3. Cons tan ts : Mol. w g t . - 166.22 , Melting Pt.** sublimes, solubility in H20 very soluble with heat rise. 4. Toxic Hazard Rating: Acute Local: Irritant 1; Ingestion 1 Acute Systemic: U Chronic Systemic: U Chronic Local: Irritant 1 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 are no storage regulations; however, it should be stored in a dry place as heat Is released upon solution in water and wet ferric chloride will not catalyze the chlorination reaction. E. Lime (Code 38800) (Calcium Oxide) 1. Description: Fine white or slightly gray powder, Rhomeric Trigonal crystals. 2. Formula: CaO. 3. Toxic Hazard Rating: Acute local: Irritant 3; Ingestion 1; Inhalation 3 Acute Systemic: Ingestion 2; Inhalation 3; skin absorption 0. Chronic local: Irritant 3; Inhalation 2 Chronic Systemic: Ingestion 2 ; Inhalation 3: Skin absorption 0. 4. Toxicology: Has a caustic reaction and, therefore, is irritating to the skin. As a dust it can cause dermatitis and irr.;.:i of the eyes and mu cons membranes. It is a gencrcii a; type of dust. 5. Fire Hazard: None 6. Explosion Hazard: Virtually none NEV 024927 738182 Dept* 246 - Standard Manufacturing Process AROCLOR APPENDIX J (Cont'd) SAFETY AND TOXICITY DATA (Cont'd) E. (Cont'd) 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 neutrilize any liberated HC1 and prevent sublimation of the FeCl3 catalyst. It is handled in 50// bags. F. ` Nitrogen (Code 43099) 1. Description: Colorless gas 2. Formula: N2 3. Constants: Mol. W t . 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. G. Aroclors 1. Recommended maximal atmospheric concentrations (MAC for eight hours): a. Aroclor 1242 - 1.0 mg per cubic meter of air b. Aroclor 1254 - 0.5 mg per cubic meter of air 2. Hazards and Control 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 temper atures, the hazard of inhalation is considered slight or absent. When these materials arc sub jected to elevated temperatures, the process either should be completely enclosed or other adept; it r mechanical exhaust ventilation must be prov ided *- o reduce concentrations to safe levels. b. Skin contact: Operations and handling procedures shou 1d b e su ch a s to "xiid th ? pw ;ib :1 i:> '" longed or repented svi:. contact. fon tam 1u a clothing must be laundered before reuse.

Eye contact: Goggles or face shield should be used where there is a possibility of liquid splashes. 3. Etaergency 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 administered if breathing is difficult. Eyes contaminated with chlorodiphenyl should be irrigated with water for at least IS minutes and the patient should be seen by a physician. Special procedures: Persons who are regularly or repeatedly exposed to chlorodiphenyIs 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. NEV 02*929 738184
