APPENDIXA UP RR SHSP—HAZARDOUS PROPERTY INFORMATION Explanations and Footnotes A Water solubility expressed as 0.2 g means 0.2 grams per 100 grams of water at 20°C. Water solubility is expressed in different terms in different references. Many references use the term"insoluble"for materials that will not readily mix with water,such as gasoline. However,most of these materials are water soluble at the part per million or part per billion level. Gasoline,for example,is nearly insoluble and will be found as a discrete layer on top of the ground water. But certain gasoline constituents,such as benzene,toluene,and xylene,will also be found in solution in the ground water at the part per million or part per billion level. B Solubility of metals depends on the compound in which they are present. C Specific gravity is the ratio of the density of a substance to the density of a reference substance. For solids and liquids,the reference substance is water;for gases, the reference substance is air. Specific gravity is expressed in units of g/cc(for solids and liquids)or g/I(at 0°C and 760 mm Hg)for gases. DI Vapor density is the weight/unit volume expressed as grams/cubic centimeter liquids. E Flash point is the temperature at which a liquid or volatile solid gives off sufficient vapor to form an ignitable mixture with the air. Flash points may be determined by the open cup method or closed cup method. Several chlorinated hydrocarbons exhibit no flash point in the conventional sense,but will burn in the presence of high energy ignition sources or will form explosive mixtures at temperatures above 200°F. F Vapor pressure is the pressure at a given temperature of a vapor in equilibrium with its liquid or solid form. It is expressed as mm Hg at 1 atm. Temperatures vary...see chart. G Lower explosive limit(LEL)and Upper explosive limit(UEL)are the minimum and maximum concentrations of a gas or vapor in air that will support flame. LEL and UEL are expressed as%in air at ambient or room temperature. H LD50 is the quantity of a substance administered by ingestion that is necessary to kill 50%of the test animals exposed to it within a specified time. I Threshold limit value as a time-weighted average(TLV-TWA)is the concentration for a normal 8-hr workday and 40-hr work week to which nearly all workers may be repeatedly exposed,day after day,without adverse effect. Values reported are the current ACGIH Threshold Limit Value-Time Weighted Average(TLV-TWA) and OSHA Permissible Exposure Limit(PEL). All PELs are based on pre-1989 values,per OSHA's 1993 decision to vacate the 1989 PELs. 1 Immediately Dangerous to Life and Health(IDLH)concentrations represent the maximum concentrations from which,in the event of a respirator failure,one could escape within 30 minutes without a respirator and without experiencing any escape-impairing or irreversible health effects. K Recommended Respiratory Protection/Max. Use Concentration is used to show the limits for respirator style and contaminant concentration. The codes in the table refer to the following: =Half-face,air-purifying respirator FF=Full-face,air-purifying respirator OV=Organic vapor canisters HEPA=High Efficiency Particulate Air canisters PAPR=Powered Air-purifying Respirator The Odor Threshold is the lowest concentration at which one may detect an odor or experience a warning effect such as taste,eye irritation,etc.,which varies with individual susceptibility. L Hazard Property: A-Corrosive D-Volatile G-Carcinogen B-Flammable E-Reactive H-Infectious C-Toxic F-Radioactive I-Reproductive Toxin Note: A reproductive toxin is a compound(chemical)that affects the reproductive organs(generally the sperm and eggs,but sometimes the physical structure of the testes or ovaries,too). It can affect the reproductive organs of males,females,or both;it can affect the reproductive organs of an adult or child,-it can affect the reproductive organs of a developing fetus with or without affecting the mother. M Dermal toxicity data is summarized in the following three categories: 1. Skin Penetration A-negligible penetration(solid-polar) + B-slight penetration(solid-nonpolar) ++ C-moderate penetration(liquid/solid-nonpolar) +++ D-high penetration(gas/liquid-nonpolar) 2. Systemic Potency E-Slightly Toxic (LD50=5-15 g/kg) Lethal dose for 70 kg adult=1 pint to 1 quart F-Moderately Toxic (LD50=0.5-5 g/kg) Lethal dose for 70 kg adult=1 ounce to 1 pint G-Extremely toxic (LD50=5-50 mg/kg) Lethal dose for 70 kg adult=7 drops to 1 teaspoon 3. Local Potency H-slight-reddening of the skin I-moderate-irritation/inflammation of skin J-extreme-tissue destruction/necrosis N Acute Exposure Symptoms A-abdominal pains G-diarrhea M-respiratory irritation B-central nervous system depression H-drowsiness N-skin C-comatose I-dyspnea 0-tremors D-convulsions J-fever P-unconsciousness E-confusion K-headache Q-vomiting F—dizziness L-nausea R-weakness
