HAZARD IDENTIFICATION EMERGENCY OVERVIEW: Chlorine Trifluoride is an extremely toxic, corrosive, water-reactive, oxidizing, colorless, liquefied gas, with a suffocating, sweet odor. Chlorine Trifluoride liquefies easily and the liquid is greenish yellow. Chlorine Trifluoride is a powerful, corrosive irritant to skin, eyes and mucous membranes; however, on-set of symptoms may be delayed. Inhalation over-exposure to Chlorine Trifluoride can lead to potentially fatal lung disorders. Although Chlorine Trifluoride is not flammable, it will enhance the burning rate of all combustible materials and may cause spontaneous ignition of such materials. Chlorine Trifluoride is one of the most powerful oxidizing and highly reactive materials known and reacts with nearly all organic and inorganic substances (including concrete). Chlorine Trifluoride is heavier than air, and pockets of this gas can accumulate in low-lying areas. Extreme caution must be used when responding to releases. Persons who respond to releases of this product must protect themselves from inhalation of the Chlorine Trifluoride gas and mists, especially in areas which are downwind of the release. SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: Chlorine Trifluoride is toxic by all routes of HAZARDOUS MATERIAL INFORMATION SYSTEM exposure. Symptoms of exposure by all routes of exposure may be delayed. HEALTH (BLUE) 4 INHALATION: Inhalation of Chlorine Trifluoride can cause severe health effects, even at relatively low concentrations. This gas causes severe irritation of the nose and throat. Other symptoms of over-exposure to Chlorine Trifluoride gas include (RED) 0 coughing, excessive salivary and sputum formation, labored FLAMMABILITY breathing, and sore throat. In some instances, unconsciousness and potentially fatal lung disorders (e.g., chemical pneumonitis and pulmonary edema) may occur. Symptoms of pulmonary (YELLOW) 3 edema can be delayed. Severe inhalation over-exposures can REACTIVITY lead to hypocalcemia, a life-threatening lowering of serum calcium in the body, due to the formation of fluorides upon contact with the moisture in the lungs. Inhalation of this gas may PROTECTIVE EQUIPMENT X be fatal. Repeated Chlorine Trifluoride over-exposures by inhalation can EYES RESPIRATORY HANDS BODY result in emphysema and erosion of teeth and a condition known as fluorosis. See Section 8 CONTACT WITH SKIN or EYES: Direct exposure to the skin from the gas or liquid can cause severe burns in seconds. Burns For routine industrial applications may not be immediately painful or visible. Depending on the nature of the exposure, the effects can be immediate or delayed. Subcutaneous tissues can be affected by over- exposure, causing tissues to become blanched and bloodless. Gangrene of affected areas may follow. Minor contact with the eyes will cause tearing and irritation as Chlorine Trifluoride is a lachrymator. Severe over- exposure to the eyes will cause burns, resulting in blindness. SKIN ABSORPTION: Chlorine Trifluoride can decompose upon contact with moisture to form hydrofluoric acid, which can penetrate the skin, causing destruction of the deep tissue layers, including bone tissue. This damage to the body’s tissues may continue for days, as the fluoride ion reacts with the calcium in the skin and bone. Severe skin-contact exposures (especially when the skin contamination exceeds 160 cm2) can lead to hypocalcemia, a life-threatening lowering of serum calcium in the body. HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure to Chlorine Trifluoride may cause the following health effects: ACUTE: This gas is extremely corrosive, and can burn and damage eyes, skin, mucous membranes, and any other exposed tissue. If inhaled, irritation of the respiratory system may occur, with coughing, and breathing difficulty. Over-exposure to this gas may cause the extremely dangerous condition of pulmonary edema (an accumulation of fluid in the lungs) and may be fatal. Though unlikely to occur during occupational use, ingestion of large quantities may be fatal. Severe exposure to Chlorine Trifluoride can result in hypocalcemia, which can be fatal unless treated. Hypocalcemia is possible in all instances of inhalation or ingestion or whenever exposure has caused large areas of burns. CHLORINE TRIFLUORIDE - ClF3 MSDS EFFECTIVE DATE: JUNE 1, 1998 PAGE 2 OF 9 3. HAZARD IDENTIFICATION (Continued) CHRONIC: Persistent irritation may result from repeated exposures to this gas. Repeated Chlorine Trifluoride overexposures by inhalation can result in emphysema and erosion of tooth enamel. Though not anticipated to be a significant hazard associated with routine use of this gas, chronic ingestion of high concentrations of fluoride compounds in water supply can cause mottled enamel of teeth and osteosclerosis. Repeated over-exposure can lead to the condition fluorosis, which is a weakening and degeneration of bone structure. Damage may also occur to the heart, central nervous system and gastrointestinal system. TARGET ORGANS: Respiratory system, skin, eyes, skeletal structure, cardiac and central nervous systems. 4. FIRST-AID MEASURES RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS PRODUCT WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self- Contained Breathing Apparatus and Chemically-Resistant Personal Protective equipment should be worn. Remove victim(s) to fresh air, as quickly as possible. Only trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation, if necessary. SKIN EXPOSURE: If Chlorine Trifluoride gas or liquid contaminates the skin, immediately begin decontamination with running water. Minimum flushing is for 15 minutes. Calcium gluconate gel should be applied to affected areas. Remove exposed or contaminated clothing, taking care not to contaminate eyes. Victim must seek immediate medical attention. EYE EXPOSURE: If liquid is splashed into eyes, or if irritation of the eye develops after exposure to liquid or gas, open victim's eyes while under gentle running water. Use sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 15 minutes. Administer anesthetic eye drops after one minute of flushing if victim suffers from spasms to the eyes, in order to facilitate irrigation. Because of the special hazard of fluoride compounds, special treatment procedures are administered to victims of exposure to Chlorine Trifluoride. Physicians should refer to Section 11 (Toxicological Information) for specific recommendations to physicians. Victim(s) must be taken for medical attention. Rescuers should be taken for medical attention, if necessary. Take copy of label and MSDS to physician or other health professional with victim(s). 5. FIRE-FIGHTING MEASURES FLASH POINT: Not applicable. AUTOIGNITION TEMPERATURE: Not applicable. FLAMMABLE LIMITS (in air by volume, %): NFPA RATING Lower (LEL): Not applicable. FLAMMABILITY Upper (UEL): Not applicable. FIRE EXTINGUISHING MATERIALS: Use extinguishing agent 0 appropriate for surrounding materials in a fire. Use water spray to keep fire-exposed containers cool. HEALTH 4 3 REACTIVITY UNUSUAL FIRE AND EXPLOSION HAZARDS: Chlorine Trifluoride is W very toxic via inhalation and skin contact; this gas presents an extreme OX health hazard to firefighters. This gas is a powerful oxidizer which will support and accelerate combustion. As a strong oxidizing gas, OTHER Chlorine Trifluoride presents severe reactivity hazards, as it is readily capable of detonation or explosive decomposition or reaction with a wide range of organic and inorganic materials. In the event of fire, cool containers of this product with water to prevent failure. Do not direct water directly onto the Chlorine Trifluoride release, as Chlorine Trifluoride will react with water. Explosion Sensitivity to Mechanical Impact: Not sensitive. Explosion Sensitivity to Static Discharge: Not sensitive. SPECIAL FIRE-FIGHTING PROCEDURES: Incipient fire responders should wear eye protection.

You have seen that in any period the element in Group 1 is the most electropositive and metallic in nature. As we go across a period from Group 1. to Group 17 of the main group elements, nonmetallic nature, ionisation energy, electron affinityand elecmnegativity increase, reaching a maximum at Group 17. In this way, at one extreme we have Group 1 comprising alkali metals and at the other we have Group 17 comprising non- metals, namely, fluorine, chlorine, bromine, iodine and astatine, collectively called the halogens. Halogens derive their name from the Greek words, halos + gens meaning salt producers, as they form salts in combination with metals. The most common of the salts being sodium chloride or the common salt. Halogens find a wide variety of uses in everyday life. In view of their nature and usefulness, it will be interesting to study the chemistry of halogens. After studying this unit, you should be able to: explain the occurrence, extraction and uses of halogens, describe the isolation of fluorine, list the general characteristics of halogens and describe their reactions, describe the chemistry of hydrogen halihes, halogen oxides and oxoacids, describe the chemistry and geometry of interhalogen compounds and polyhalides, and explah the anomalous behaviour of fluorine.

  • Vapor Pressure 6-60
    VAPOR PRESSURE This table gives vapor pressure data for about 1800 inorganic and organic substances. In order to accommodate elements and compounds ranging from refractory to highly volatile in a single table, the temperature at which the vapor pressure reaches specified pressure values is listed. The pressure values run in decade steps from 1 Pa (about 7.5 µm Hg) to 100 kPa (about 750 mm Hg). All temperatures are given in °C. The data used in preparing the table came from a large number of sources; the main references used for each substance are indicated in the last column. Since the data were refit in most cases, values appearing in this table may not be identical with values in the source cited. The temperature entry in the 100 kPa column is close to, but not identical with, the normal boiling point (which is defined as the temperature at which the vapor pressure reaches 101.325 kPa). Although some temperatures are quoted to 0.1°C, uncertainties of several degrees should generally be assumed. Values followed by an “e” were obtained by extrapolating (usually with an Antoine equation) beyond the region for which experimental measurements were available and are thus subject to even greater uncertainty. Compounds are listed by molecular formula following the Hill convention. Substances not containing carbon are listed first, followed by those that contain carbon. To locate an organic compound by name or CAS Registry Number when the molecular formula is not known, use the table Physical Constants of Organic Compounds in Section 3 and its indexes to determine the molecular formula.
