Odorant nonirritating

Carbon tetrachloride [56-23-5] (tetrachloromethane), CCl, at ordinary temperature and pressure is a heavy, colorless Hquid with a characteristic nonirritant odor it is nonflammable. Carbon tetrachloride contains 92 wt % chlorine. When in contact with a flame or very hot surface, the vapor decomposes to give toxic products, such as phosgene. It is the most toxic of the chloromethanes and the most unstable upon thermal oxidation. The commercial product frequendy contains added stabilizers. Carbon tetrachloride is miscible with many common organic Hquids and is a powerhil solvent for asphalt, benzyl resin (polymerized benzyl chloride), bitumens, chlorinated mbber, ethylceUulose, fats, gums, rosin, and waxes. 

Health Hazards Information - Recommended Persoruil Protective Equipment Self-contained breathing apparatus for high vapor concentrations Symptoms Following Exposure In high vapor concentrations, can act as simple asphyxiant. Liquid causes severe frostbite General Treatment for Exposure Remove from Exposure, support respiration Toxicity by Inhalation (Threshold Umit Value) Not pertinent Short-Term Exposure Limits Not pertinent Toxicity by Ingestion Not pertinent Late Toxicity None Vapor (Gas) Irritant Characteristics Vapors are nonirritating to the eyes and throat Uquid or Solid Irritant Characteristics Not pertinent appreciable hazard. Practically harmless to the skin because is very volatile and evaporates quickly Odor Threshold 899 ppm. 

Health Hazards Information - Recommended Personal Protective Equipment Chemical goggles or face shield Symptoms Following Exposure Low toxicity liquid may irritate eyes General Treatment for Exposure Flush all affected parts with plenty of water Toxicity by Inhalation (Threshold Limit Value) Data not available Short-Term Inhalation Limits Data not available Toxicity by Ingestion Grade 2 oral rat LDjo = 1.87 g/kg Late Toxicity Data not available Vapor (Gas) Irritant Characteristics Nonirritating Liquid or Solid Irritant Characteristics Liquid may irritate eyes it is not irritating to skin Odor Threshold 0.49 ppm. 

NUTRITIONAL IMBALANCE The antiviral dragp may-cause anorexia, nausea, or vomiting. These effects range from mild to severe. The patient may be able to tolerate small, frequent meals with soft, nonirritating foods if nausea is mild. Frequent sips of carbonated beverages or hot tea may be helpful for others. It is important to keep the atmosphere clean and free of odors. The nurse provides good oral care before and after meals. If nausea is severe or the patient is vomiting, the nurse notifies the primary health care provider. 

HFC-134a is a nonflammable, colorless gas or liquified gas with a faint ethereal odor. The odor, characterized as weak and nonirritating (Shulman and Sadove 1967), may not be noticeable for most individuals and thus will not serve as a warning property. The vapor is heavier than air and can displace air in confined spaces (ECETOC 1995). Additional chemical and physical properties are listed in Table 3-2. 

Chloroform is also known as trichloromethane or methyltrichloride. It is a colorless liquid with a pleasant, nonirritating odor and a slightly sweet taste. Most of the chloroform found in the environment comes from industry. It will only bum when it reaches very high temperatures. Chloroform was one of the first inhaled anesthetics to be used during surgery, but it is not used for anesthesia today. Nearly all the chloroform made in the United States today is used to make other chemicals, but some is sold or traded to other countries. We also import chloroform. 

Arsine is nonirritating with a garlic-like odor. Warning properties of exposure to hazardous concentrations are inadequate. ... 

Nonirritant to the nasal and bronchial passages, and not possessing an odor. 

Arsine, the most toxic form of arsenic, exhibits some characteristics that may make it useful as a chemical warfare (CW) agent. Arsine is a colorless, odorless, nonirritating gas and is 2.5 times denser than air (Henriksson et al, 1996 Pullen-James and Woods, 2006 Thomas and Young, 2001). At concentrations above 0.5 ppm, a garlic-like odor may be noted, but arsine is toxic at much lower concentrations. Acute arsine poisoning due to inhalation of arsine gas (AsHs) is rare but has no known antidote. It is the most acutely toxic form of arsenic causing rapid and severe hemolysis immediately on exposure. The mechanisms of hemolysis are not completely understood. Arsine has a short half-life (27-96 h) and is converted to various arsenic derivatives. Although it...
