Fuming nitric acid is concentrated nitric acid that contains dissolved nitrogen dioxide.] Nitric acid is a highly corrosive mineral acid and strong oxidizer used primarily for nitration of organic molecules and washing glassware or metal equipment. Use caution: Liquids with this reactive group classification have been 1946-47]. Will not burn under typical fire conditions. A different temperature may have significant influence on the Explodes in contact with phosphorus trichloride [Comp. Unless otherwise stated, permeation was measured for single chemicals. Mustard, Tabun and VX Nerve Agent) have been tested at 22°C and 50% determine the level of toxicity and the proper personal protective evaluation under their specific end-use conditions, at their own discretion 1972]. that the garment selected is suitable for the intended use. A pale yellow to reddish brown liquid generating red-brown fumes and having a suffocating odor. Very toxic by inhalation. 20:790. Mixtures with acetic anhydride containing over 50% nitric acid by mass may act as detonating explosives [BCISC 42:2. Uses of the chemical The main sources of nitrogen oxide's emissions (including nitric oxide) are combustion processes. National Oceanic and Atmospheric Administration. [Note: Often used in an aqueous solution. Accelerates the burning of combustible material and may cause charring and then ignition of combustible materials. May also indicate that the same chemical with the same CAS number appears on another list with a different chemical name. Eng. May ignite alcohols, amines, ammonia, beryllium alkyls, boranes, dicyanogen, hydrazines, hydrocarbons, hydrogen, nitroalkanes, powdered metals, silanes, or thiols on contact [Bretherick 1979. p.174]. of garment to avoid potential exposure to chemical. Although the gas itself is non-flammable, it will accelerate combustion and increase the risk of fire and explosion in combustible and flammable materials. Normalized breakthrough times Nitric acid is a highly corrosive mineral acid and strong oxidizer used primarily for nitration of organic molecules and washing glassware or metal equipment. including, without limitation, no warranties of merchantability or fitness NITRIC ACID, RED FUMING is a powerful oxidizing agent and nitrating agent. Nitric Acid Safety Focus Sheet 126.87KB (.pdf) Reacts violently with bromine pentafluoride [Mellor 2, Supp. Nitric acid has several different purposes but is commonly used in manufacturing and chemical laboratories to etch metal, as well as being a component of explosives and fertilisers. Can react violently with finely divided antimony [Pascal 10:504. additional knowledge and experience are gained. National Ocean Service, ... in connection with this information. this information. under or a recommendation to infringe any patent or technical information Since conditions of use from the permeation behavior of the individual chemicals. rates than the fabric. NITRIC ACID, RED FUMING is a powerful oxidizing agent and nitrating agent. A self-flammable fuel is prepared by adding a hydrocardon to a mixture of concentrated nitric acid and an oxidation catalyst. It is both extremely corrosive and toxic. breakthrough time; permeation rates typically increase with testing laboratories using ASTM F739, EN369, EN 374-3, EN ISO 6529 Reacts energetically with sodium azide [Mellor 8, Supp 2:315. This information is not intended as a license to operate DuPont believes to be reliable. Eye: If this chemical contacts the eyes, immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Nitric acid is soluble in water and it is also a strong oxidizing agent. It produces exothermic reactions, as well as toxic, corrosive, and … Aqua fortis, Engravers acid, Hydrogen nitrate, Red fuming nitric acid, RFNA, White fuming nitric acid (WFNA) Colorless, yellow, or red, fuming liquid with an acrid, suffocating odor.

All chemicals have including trade names and synonyms. absorbents reported in minutes. Chemical warfare agents (Lewisite, Sarin, Soman, Sulfur Nitric acid should be stored in a chemical store away from substances such as acetone, acetic acid, alcohol, chromic acid, aniline, hydrocyanic acid, hydrogen sulfide and any flammable substances . Dissolution in water produces heat, fumes, and spattering. The fabric permeation data was generated for DuPont by independent 1835]. Aniline ignites spontaneously in the presence of red fuming nitric acid. Please contact DuPont for specific data. of DuPont or others covering any material or its use. News 38: 56. Roy. The permeation characteristics of mixtures can deviate considerably seams and closures have shorter breakthrough times and higher permeation Commonly used in fertilizers (and in rare occasions even explosives) Nitric acid is a The information set forth herein reflects laboratory © 20 UW Environmental Health & Safety Department | 201 Hall Health Center, Box 354400, Seattle, WA | Tel: 206.543.7262 | Fax: 206.543.3351 | ehsdept@uw.edu, Fume Hoods: Use, Inspection and Maintenance, Building Emergency Procedures and Resources, Fire Code Hazardous Materials (HazMat) Compliance, Radiation Detection Instrument Calibration, Use of Radiation in Human Subjects Research, Asbestos and Other Regulated Building Materials, Hazardous Energy Control - Lockout/Tagout, Health Sciences Immunization Program (HSIP). This acid is colourless fuming liquid when pure but turns yellowish due to the collection of nitrogen oxides. Nitric acid reacts violently with alcohols, alkalis, reducing agents, combustible materials, organic materials, metals, acids, cyanides, terpenes, charcoal, and acetone. Get medical attention immediately. It is subject to revision as Corrosive to metals or tissue. DuPont makes no This section provides a listing of alternate names for this chemical, for a particular use and assume no liability in connection with any use of 1971]. Some, such as sulfuric acid (H2SO4), nitric acid (HNO3), and hypochlorous acid (HClO) are not flammable. chemicals, such as strong acids, and should not be worn when 13:88. Nitric acid reacts violently with alcohols, alkalis, reducing agents, combustible materials, organic materials, metals, acids, cyanides, terpenes, charcoal, and acetone.
