  1. Hazardous Materials Emergency Response Training

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

  3. 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!

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

  5. Barton Solvents Flammable Liquid Explosion and Fire Synthron Chemical Explosion Pictures Courtesy of CSB Veolia Environmental Services Flammable Vapor Explosion and Fire Huge blaze erupts at Oklahoma chemical plant following container explosions Williams Olefins Plant Explosion and Fire

  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 • 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. Essential Knowledge for Dealing with Hazardous Materials

  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

  11. Physical & Chemical Properties

  12. Simple Hazard Analysis / Risk Assessment

  13. Simple Hazard Analysis / Risk Assessment

  14. Simple Hazard Analysis / Risk Assessment

  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 be @ Flash Point to burn, given a ignition source is present. • Polar Solvents “OH” Mix with water • Temperature always affects Pressure

  16. Todays Demonstrations • Physical State • Flash Point • Boiling Point • Vapor Pressure • Vapor Density • Specific Gravity • Solubility Polar /vs/ Non-Polar • Lower Explosive Limit // Upper Explosive Limit • Surface Area / vs / Reaction Rate • Static Electricity • Stoichiometric Reactions • Expansion Ratio

  17. DYNAMIC TENDANCIES OFHazardous 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!
