[Note: Shipped as a liquefied compressed gas. In small concentrations the gas is detectable by smell. While it looks like the fish mortality should be very high, the fish are doing fine. J Ind Hyg Toxicol, Smyth HF Jr [1956]. AVSHIPS 250-649-1. TSA-20-72-3, pp. Ammonia is a colourless, reactive gas that is lighter than air (approximately half as heavy) which dissolves readily in water. CAS number: 7664-41-7 NIOSH REL: 25 ppm (18 mg/m3) TWA, 35 ppm (27 mg/m3) STEL Current OSHA PEL: 50 ppm (35 mg/m3) TWA 1989 OSHA PEL: 35 ppm (27 mg/m3) STEL 1993-1994 ACGIH TLV: 25 ppm (17 mg/m3) TWA, 35 ppm (24 mg/m3) STEL Description of substance: Colorless gas with a pungent, suffocating odor. Not perfect, but not a disaster. 1. If ammonia levels are higher than zero, you need to find the cause of the problem, and fast. Henderson Y, Haggard HW [1943]. U.S. Navy Standards [U.S. Bureau of Ships 1962] Maximum allowable concentrations (MACs): Other animal data:RD50 (mouse), 303 ppm [Appelman et al. Noxious gases. Back KC, Thomas AA, MacEwen JD [1972]. The product typically is 99.98% pure with minimal levels of moisture and other impurities (< 200 ppm and < 5 ppm Oil) making it ideal for use in all types of refrigeration systems. Emergency and continuous exposure guidance levels for selected airborne contaminants. Damage of mucous membranes with more than one hour exposure, Fatal after short exposures - less than half an hour. PPM Levels PPM (Parts Per Million) refers to the concentration of the particulates in your feeding solution. Solutions of ammonia are alkali and can be corrosive when concentrated. New York, NY: Academic Press, Inc., p. 607. Maximum exposure 15 minutes. Silverman L, Whittenberger JL, Muller J [1946]. Ace ammonia is 10% concentration; Ammonia Clear is around 5% … Ammonia is also flammable at concentrations of approximately 15% to 28% by volume in air. Flury F [1928]. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Easily liquefied under pressure.] R717 (Ammonia) Pressure Enthalpy Chart. CDC twenty four seven. At a pH of 6.0, and 10 ppm of TAN, the ammonia is only .007 ppm. Kills: M.tuberculosis, HBV, HAV, HIV at 1000ppm available chlorine, C. difficile at 5000 ppm in under 10 minutes, E. coli in 30seconds, H. pylori at 150 ppm in 30seconds, Norovirus at 1000ppm in 1min, SARS at 1000ppm in 1min, anthrax at 5250ppm in 5 mins, B. atrophaeus at 100ppm in 5 minutes, Candida and salmonella at 500ppm in 30seconds and P.aeruginosa in under 10 minutes. of liquid ammonia at its saturation pressure; Parts per million - ppm - ppm - parts per million - commonly used as a unit of concentration et al. A change in respiration rate and moderate to severe irritation has been reported in 7 subjects exposed to 500 ppm for 30 minutes [Silverman et al. This calculator estimates the weight and volume of ammonium hydroxide solution required to reach a target ammonia level in an aquarium. Description of substance: Colorless gas with a pungent, suffocating odor. I did a 25% water change the day before yesterday. In a stocked tank, your aquarium test kit reading for ammonia should read 0 ppm (parts per million). Environmental, Safety and Health Group . You can target the Engineering ToolBox by using AdWords Managed Placements. J Haz Mat. Might try placing the test vial on the colour patch on the chart and viewing it from above. Although a standard ammonia test kit can only show the combined amount of ammonia and ammonium present in the aquarium, the reading should be compared to a chart relating ammonia to pH levels. Example: I have a tank at 27 deg with pH 6.6 water and 2.0 ppm of ammonia. ESHG-Health-01.00 . Liquid ammonia - Thermal Properties at saturation pressure - Density, specific heat, thermal conductivity, viscosity and Prandtls no. Ammonia is a compound of nitrogen and hydrogen with the formula NH 3.A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. Maintaining this chart might seem a boring thing to anyone but for proper growth, it is mandatory. Moderate eye irritation, no long-term effect in exposures of less than 2 hours, Moderate throat irritation. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! AIHA [1971] also reported that 5,000 to 10,000 ppm are reported to be fatal [Mulder and Van der Zahm 1967] and exposures for 30 minutes to 2,500 to 6,000 ppm are considered dangerous to life [Smyth 1956]. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Reclassification of materials listed as transportation health hazards. Existing short-term exposure: recognized by odor. Introduction R717 is refrigerant grade high purity ammonia (NH 3). Ammonia - NH3 - is a gas commonly used as a refrigerant in cooling systems. Scroll down to find download buttons for pressure enthalpy charts in either Metric or Imperial Units. and Austin’s Clear Ammonia (available on Amazon).. Some of our calculators and applications let you save application data to your local computer. With a higher ammonia concentration ranging from 72–134 ppm, the same irritation can occur in half the time. Time for a water change? So, .25 is sort of a compromise between the ideal of zero and more than .25. 2011. Basis for original (SCP) IDLH: The chosen IDLH is based on the statement by AIHA [1971] that 300 to 500 ppm for 30 to 60 minutes have been reported as a maximum short exposure tolerance [Henderson and Haggard 1943]. Under normal circumstances the concentration of ammonia in the circulation remains low, typically less than 50 μmol/L (85 μg/dL). The gas is colorless with very sharp odor. A-172 to A-173. An average person detects ammonia by odor at around 17 ppm. Concentration solution unit conversion between milligram/liter and part per million, part per million to milligram/liter conversion in batch, mg/L ppm conversion chart Experimental ammonia gas poisoning in rabbits and cats. Only iron, steel, certain rubbers and plastics, and specific nonferrous alloys resistant to ammonia should be used for fabrications of anhydrous ammonia containers, fittings, and piping. 1988 American Industrial Hygiene Association (AIHA) Emergency Response Planning Guidelines (ERPGs), National Research Council [NRC 1987] Emergency Exposure Guidance Levels (EEGLs). Ammonia gas is non-flammable, but because at certain concentrations when mixed with air it could explode if ignited, it is treated as flammable.
