Chapter 2 - Properties of HazMat
"By the Numbers"
▪ The body can sustain a small fluctuation of 2oF below or 3oF above the normal core temperature of 99.7oF.
▪ Body temperature of 105oF or higher is suggestive of heatstroke.
▪ One way to prevent and/or reduce of the effects of heat exposure is to drink 7 ounces of fluid every 15 to 20 minutes.
▪ A liquified gas, such as propane or carbon dioxide, is one that at the charging pressure is partially liquid at 70oF.
▪ Cryogens turn from gas to a liquid at or below -130oF.
▪ Beta radiation particles are about 1/7000th the size of alpha particles but have more penetrating power.
▪ X-rays and gamma rays move at the speed of light (186,000 miles/second).
▪ Convulsants can cause muscle spasms to occur at varying intervals from 3 to 30 minutes.
▪ Disease and complications from exposure to carcinogens can occurs as long as 20 years after exposure.
▪ TLV-TWA of a material is the maximum airborne concentration to which an average person may be exposed repeatedly for 8 hours each day, 40 hours per week without suffering adverse effects.
▪ TLV-STEL value is the 15 minute, time-weighted average exposure that should not be expected at any time or repeated more than 4 times per day with a 60 minute rest period required between each exposure.
▪ Employees should not be allowed to work in a TLV-STEL area longer than 15 minutes without proper PPE.
▪ PELs are the maximum amount of exposure for an 8 hour work day.
▪ LD50 is the minimum amount of solid or liquid that when ingested, absorbed, or injected through the skin will be fatal to 50% of all subjects exposed to that dosage.
▪ LC50 of a substance is the minimum concentration of an inhaled substance in the gaseous state that will be fatal to 50% of the test group.
▪ Flammable liquids, such as gasoline and acetone, are those which have flash points below 100oF.
▪ Combustible liquids, such as fuel and lubricating oils, are those which have flash point above 100oF.
▪ With the exception of a few solids, such as napthalene (174oF flash point), solids are not considered to have flash points.
▪ The autoignition temperature of gasoline is 536oF, while the temperature at which it can be ignited by an independent ignition source is -45oF.
▪ Any concentration above 10% of the LEL must be considered as a serious ignition potential.
▪ Water has a specific gravity of 1.0 and liquids with less than 1 will float and more than 1 will sink.
▪ Most flammable liquids have a specific gravity less than 1 (float on water).
▪ Air has a vapor density of 1.0, which means gases with a vapor density less than 1 will rise in air and more than 1 will sink and hover around ground level.
▪ At 212oF, water changes from a liquid to a gaseous state.
