6. Physical & Chemical Properties
Significant in Assessing Hazards and Managing Risk;
Will it Hurt Me? How?
IDLH, TWA /PEL values
Identifying your “TARGET”
Qualitative / Quantitative Analysis Using Instrumentation.
Necessary for proper PPE selection

7. Physical / Chemical Properties
Essential Knowledge for Dealing with Hazardous Materials
Physical Properties: Observed or measured without changing the composition of matter. Physical properties are used to observe or describe matter. Chemical Properties: Describe how substances have the ability to undergo reactions and form new substances.

8. CHEMICAL PROPERTIES
Minimum temperature that a substance gives off vapors sufficient to burn in the presence of an ignition source
FLASH POINT Fire Point Flammable Limits Auto Ignition Temperature Toxicity Stability Reactivity Ionization Potential
Minimum temperature that a substance will continue to burn in the absence of ignition source
Explosive range or
LEL / UEL
Temperature at which a substance will spontaneously ignite with out the presence of an ignition source

9. PHYSICAL PROPERTIES
Fuel State of Matter
SOLID / LIQUID / GAS Boiling Point Vapor Pressure Volatility Specific Gravity Vapor Density Solubility
Temperature at which the pressure of the vapors = atmospheric pressure
Molecules escaping from liquid or solid
How readily a substance vaporizes. Substances that vaporize at room temperature are considered to be Volatile
Relationship of substance to water
Relationship of substance to Air
Ability of Solute to dissolve in solvent

10. Flammable Liquids Physical Relationships

15. Physical / Chemical Properties “Hazmat Response Constants”
Air= 14.7 Psi / 760 mmHg
29 AMU
Water= 8.34 lbs/gal
1% = 10,000 ppm
Branching: Lowers Boiling Points
Materials must Flash Point to burn, given a ignition source is present.
Polar Solvents “OH” Mix with water
Temperature always affects Pressure

17. DYNAMIC TENDANCIES OF Hazardous Materials
WARNING STATEMENT! The demonstrations you are about to see, have been laboratory tested, and performed through research and development methods. It is strongly recommended that you do not attempt to try this yourself. These are hazardous materials, and they can pose serious harm and even death if not treated with respect!
