Reactive Perspective
Crisis management, people wait until something happens and then they react to it.
Retrospective Perspective
Looking back at past events
Prospective Perspective
Predict what will go wrong so we can try to prevent or mitigate something that could happen.
Ozone Depleters
Methanol
Radioactive Debris
Acid Rain
CFC
How to calculate a TWA and interpret?
TWA= Concentration PPM X TIME in hr/8hours
Five Key elements of PPE program?
Hazard Identification Medical Monitoring Continuous environmental surveillance Equipment selection use maintenance and decontamination Training and administration
How long to keep medical records?
30 years after the end of employment
Two objectives of a PPE program?
Protect user from hazardous exposure
prevent injury to the user from PPE misuse of malfunction
What are APR’s and when to use and not use?
Air-purifying respirator. Don’t use in Oxygen deficiency, IDLH, uncharacteristic confined space
What is a SCBA and when to use and not use?
Self- contained breathing apparatus. Use in an Oxygen deficiency atmosphere.
What is a protection Factor and how is it used?
It is used to determine the MUC (Maximum use concentration)
What are Warning Properties?
Odor, Taste, or irritating effects
Levels of protection and difference between levels
Level A-fully enclosed suit with SCBA
Level B- suit not fully enclosed with SCBA
Level C- Same suit as B with APR
Level D
What should a written IH plan address?
Hazard Recognition
Hazard Evaluation
Hazard Control
Personnel Training
Oxygen deficient atmosphere is?
Less than 19.5%
What is penetration, degradation, permeation as it applies to CPC?
Degradation, result of a chemical reaction between contaminant and protective material. Penetration, due to imperfections in design or construction. Permeation, concentration gradient.
Criteria for using measurement devices when sampling?
Needs to be accurate and precise.
