Appendix J Safety and Toxicity Data IH.(Cont'd) A. (Cont'd) 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 p p m ) . The compound, or organic solutions of the compound can absorb through the intact skin; therefore, repeated skin contact should be avoided. 11. See Hygienic Guide Series on "Diphenyl". B.

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 membranes of the eyes and respiratory tract. It combines with moisture to liberate nascent oxygen and from hydro chloric acid. Both of 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. Con centrations 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 NEV 025057 738312 Department 246 - Standard Manufacturing Process Description Page 53 Section IV Comments On Process(Contd.) Appendix J Safety and Toxicity Data III. B. 5. (Cont'd) of the eys 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 Ha z a r d : 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 Chlorid 2. Description: Colorless gas. 3. formula: HC1. h. froxlc Hazard Rating: Acute l o c a l : f r r i t a n t 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 . Ifoxlcology: Hydrogen chloride is an irritant to the mucous membranes of the eyesand respiratory tract. Concentration of 35 ppm causes irritation of the throat after short exposure Concentrations of 50 to 100 ppm are tolerable for 1 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 effect. 7. See Hygienic Guicfe Series on "Hydrogen Chloride".

Ferric Chloride (Code 33500) 1. Description: Granular solid. 2. Formula! FeCl,, (Anhydrous) 3. Constants: Mol. Wgt. = 166.22, Meltln Pt. * sublimes, solubility in H 0 = very soluble with heat rise. 4. Toxic Hazard Ra c i n g : 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 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 irritation of the eyes and mucous membranes. It is a generalnuisance type of dust. 5. Fire Hazard: None. 6. Explosion Ha z a r d : Virtually none. 7. Handling: Dust respirator, adequate protective clothing, including rubber coated gloves, optional rubber ful cover apron and full cover plastic goggles should N&V 023059 738314 Department 246 - Standard Manufacturing Process Description Page 55 Section IV Comments On Process(C o n t d .) Appendix J Safety and Toxicity Data E. 7. (Cont'd) 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 43099) 1. Description: Colorless gas 2.
