3 History Issued by OSHA November 25, 1983. First issued for companies in SIC codesApplies to manufacturers and importers.
4 Hazardous Material Defined Any material that, because of its quantity, concentration, or physical or chemical characteristics, may pose a substantial hazard to human health or the environment when incorrectly used, purposefully released, or accidentally spilled.
5 What Makes a Substance Hazardous ? A material is considered hazardous if it exhibits any of the following characteristics beyond predefined levelsToxicityReactivityIgnitabilityCorrosivityBioaccummulative
6 Mixture RuleIf a mixture has not been tested as a whole, the mixture is assumed to present the same health hazards of hazardous ingredients which compromise more than one percent (0.01) of the whole.A mixture is considered to be a carcinogen if any component in concentrations of 0.10 %, or greater are carcinogenic.

54 Toxicity The quality of being poisonous; having harmful effects. "Everything is a poison, nothing is a poison, the dose alone makes the poison.” -Paracelsus,The toxicity of a substance is due to its ability to damage or disrupt the metabolism of living tissue.
55 Routes of Entry Oral = Ingestion by mouth Dermal = Skin exposure Inhalation = Absorbed by lungsOcular = Eye exposure
56 Toxic Effects May Occur: During or soon after exposure (acute), andAfter repeated exposures over a long time (chronic).In addition, some people may be especially sensitive (allergic) to a substance.
57 Acute ToxicityAn acutely toxic substance can cause damage as the result of a single or short-duration exposure
58 Chronic ToxicityA chronically toxic substance causes damage after repeated or long-duration exposureAt times, it becomes evident only after a long latency period
60 Routes of Entry"Everything is a poison, nothing is a poison, the dose alone makes the poison.” Paracelsus,

88 CHEMICAL HAZARDS Fire Hazards Explosive Hazards Toxic Hazards Corrosive HazardsChemical ReactivityPhysical Properties
89 Fire Hazards Combustibility Flammability Pyrophorics Gas or Vapor Explosions
90 Combustibility The ability of a material to act as a fuel OSHA says combustibles have flash point between 100° F and 200° FAnything that can be readily ignited and sustain a fireAnything that can’t is considered non-combustible
92 FlammabilityThe ability of a material (gas or liquid) to produce sufficient vapors to be ignited and produce a flame under normal conditions.There must be a proper fuel to air mixture to sustain combustion. Each material has its own mixture range called “Flammable Range”.
93 UFL and LFLConcentrations < the LFL will not burn because they are too “lean”.Concentrations > the UFL will not burn because they are too “rich”.
94 OSHA FLAMMABLEOSHA considers anything flammable if it has a flash point below 100°F.Flashpoint - See Section 2, page 14.
95 REGULATORY CONFUSION OSHA-Flammable: < 100°F Combustible: 100F-200°FWill Not Burn: > 200°FDOT- Flammable: < 141°FCombustible: > 141°F but < 200°FNon-Hazardous: Anything > 200°FEPA- Anything < 140°F is “Ignitable”
96 GAS OR VAPOR EXPLOSIONS A Rapid, Violent Release of EnergyLarge amounts of kinetic energy, heat and gaseous products are released.The KEY is confinement of a Flammable Material. The combustion reaction is more rapid and confinement increases energy which enhances the explosive process.
97 UEL and LELExplosive gases and vapors exhibit an explosive range which is the same as the flammable range.The UEL (Upper Explosive Limit) and the LEL (Lower Explosive Limit) are the same as UFL and LFL, but in confined areas.Again, CONFINEMENT is the Key!
98 Dose - ResponseToxic effects on human beings depends on the length and amount of exposure and the level of toxicity (its lethal dose) of the material.HAZARD = EXPOSURE + TOXICITYTherefore, as the dose (length of exposure and amount of exposure) increases the human response increases also.

100 PHYSICAL PROPERTIES OF CHEMICALS One of the most ignored parts of an MSDS is the part where Physical Properties of Chemicals are listed.Most people do not understand Physical Properties.Evaluating risk on an incident depends on understanding these properties.
101 Solubility/Miscibility The amount of chemical (solid, liquid, gas or vapor) which can be dissolved in water at 68°F. Measured in percent, the higher the percentage, the more chemical that will dissolve in water.Example: Sugar is 100% soluable.Miscibility refers, specifically, to the solubility of a liquid.
102 Density and Specific Gravity The Density of a substance is its mass per unit volume, commonly expressed in grams per cubic centimeter (g/cc).The density of water is 1 g/cc.Specific Gravity is the density of a chemical compared to that of water. If the SpG is less than 1g/cc the chemical will float. If SpG is more than 1 g/cc it will sink.
103 Vapor DensityThe Density of a gas or vapor can be compared to the ambient atmosphere. If the density of a vapor or gas is greater than ambient air, it will tend to settle.If Vapor Density is close to, or less than, ambient air it will rise or disperse in the atmosphere.Discuss hazards page 2-13.
104 Vapor Density, continued What are the hazards of a gas or vapor which will settle? Use Carbon Monoxide as an example.How about Gasoline vapors?
105 Vapor PressurePressure exerted, by a vapor, on the sides of a closed container.It is Temperature Dependent. As temperature increases, so does Vapor Pressure.The lower the boiling point of a liquid, the greater vapor pressure it will exert at a given temperature.
106 Vapor Pressure, continued Values for Vapor Pressure are most often given as millimeters of mercury (mm Hg).NIOSH HandbookExamples: Ammonia- VP= 8.5 atm (p. 262) Carbon Monoxide (p. 54)Methyl hydrazine (p. 210)Atmospheric Pressure mm Hg.
107 Boiling PointTemperature at which liquid changes to vapor. The temperature where the pressure of the liquid equals atmospheric pressure (760 mm Hg).What it the boiling point of Ammonia?What is the boiling point of Sulfuric Acid?What is the route of entry for each of these?
108 Melting PointTemperature at which a solid changes to a liquid. It is also the freezing point-depends on the direction of the change.Example: Water (ice) = 32°F
109 Flash PointThe minimum temperature at which a substance produces sufficient flammable vapors to ignite:Highly FlammableModerately FlammableRelatively Inflammable
110 Odor ThresholdThe minimum concentration of a substance in air that can be detected by the human sense of smell.It is different for each person Ammonia= 5 ppm Ethyl alcohol= 10 ppmThe ACGIH STEL for Ammonia 25 ppm. What does this mean?
