|
Infectious |
Caused by microorganisms. Not all contagious |
|
|
Contagious |
Transmitted |
|
|
Acute effects |
Present immediately |
|
|
Chronic effects |
Can be yrs |
|
|
Acute exposure |
Large concentration effects immediate or long term |
|
|
Chronic |
Repeated exposure low levels of concentration over several days or longer |
|
|
3 types of stress |
Thermal Mechanical Chemical |
|
|
Thermal stress |
Results from radiated, convected, conducted or direct heat exposure |
|
|
Mechanical stress |
From dominant physical force |
|
|
Chemical stress |
Result of rxn or interaction, may change of contents or container |
|
|
5 ways of breach |
Disintegration Run-away cracking Closures opening up Punctures Splits/tears |
|
|
Disintegration breach |
Fails due to rust/corrosion |
|
|
Run-away cracking |
Crack grows |
|
|
Closures opening up |
Incorrect op of closing mechanism |
|
|
Punctures |
Mechanical stressors, container HIT in By another object |
|
|
Splits/Tears |
From mechanical stressor, container hit in sliding motion from another object |
|
|
4 ways containers release contents |
Detonation Violent Rupture Rapid Relief Spills & Leaks |
|
|
Detonation |
Explosion of contents Unstable molecules use energy to instantaneously split into small pieceslg 🔀amts of heat♨️ |
|
|
Violent rupture |
NOT an explosion Run-away cracking Rapid acceleration polymerization Oxidizing hazmat rxns |
|
|
Rapid relief |
Pressure ruptures (over pressured/safety valve fails) |
|
|
Spills & leaks |
Gradual flow through openings Tears/splits Punctures |
|

|
Front (Term) |
Pool- liquids equally shaped ⭕️ in all directions & all areas |
|
Front (Term) |
Irregular- no definitive shape |
|
|
Factors influencing length of time (dispersion/exposure) |
Quantity Method Speed of release |
|
|
Time frames |
Short-term: min&hrs ✔️low haz ✔️quick control ✔️short release
Medium term: Days Wks & Mnths ✔️mod-high haz ✔️exposure contamination occurred ✔️Decon lengthy/ difficult ✔️ mod cleanup required
Long term: yrs & generations Not decades ✔️ high haz ✔️ heavy contam. ✔️ Decon lengthy/diff. ✔️extensive cleanup |
|
|
Factors influencing harm |
Concentration & duration |
|
|
Types of Hazards causing harm |
TEAM-CPRP Thermal-heat Etiologic-bodily fluids Asphyxiation-lung/ blood O2 deficient Mechanical-explosion Corrosive Poisonous-inhibit bio function Radiation-mutating thro waves/particles Psychological-emotional state |
