Terminoly Pt 2 Flashcards
Upper explosive level (UEL)
“Too rich to burn”
Lower explosive limit (LEL)
“Too lean to burn”
Half life
Substance undergoing decay decreased by half
Halogenated hydrocarbons
Aromatic hydrocarbons, hydrogen molecules substituted by halogen group
Ignition
Material will self-ignite and sustain cubstion in air
Inhibitor
Control chemical reaction with other products
Instability
Decompose spontaneously, polymerize or self react. “Unstable”
Ionic or covalent compounds
Sharing or transfer of electrons
Irritants
Respiratory distress/copious tearing that incapacitates victims
Maximum safe storage temperature (MSST)
Max temperature organic peroxide (5) can be stored
Melting point
Solid becomes a liquid
Freezing point
Liquid converts to solids
Miscibility
To more liquid to for uniform blend. “Solubility”
Nerve agent
Interferes with central nervous system
Organic
Includes all other compounds of carbon
Inorganic
Lacks carbon chains
Oxidation potential
Combining anything with oxygen or yielding oxygen which presents greater hazard
Persistence
Chemical ability to remain in an environment
PH
Numerical measure of hydrogen concentration related to acidity or alkalinity
Physical state
Form of material at ambient temperature (ex: Fire on stove)
Physical change
Objects undergo change which doesn’t effect chemical properties
