Hazardous Materials Emergency Response Training

The Dynamic Tendencies of Physical and Chemical Properties Presented By: HMERT Brian Ramsey

Why Demonstrate Visual Education Increased Awareness of Hazardous Materials Death by POWER POINT Increased Knowledge of Chemistry and Toxicology (What we really need to know to be SAFE!) Risk Based Response Home Safety Plus This Stuff is REALLY COOL!

Target Audience Hazmat Technicians / Specialist’s Chemical Facilities Process Safety Engineers Municipal Fire Departments Safety Professionals

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

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.

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

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

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!
