Study Notes

Hydrostatics and Hydraulics

Hydrostatic pressure is a key concept in fluid mechanics
Torricelli's Law states that the pressure of a fluid at equilibrium is proportional to the height of the fluid column
Head pressure is the pressure of a fluid due to its height or elevation
Velocity head is the pressure of a fluid due to its motion or velocity
Velocity pressure at constant laminar velocity can be calculated using the formula: ΔP = ρ * g * h
Flow rates and pressure drops are important concepts in hydraulic systems
Bernoulli's Principle states that the pressure of a fluid decreases as its velocity increases
Key information to remember on hydrostatics and hydraulics includes understanding pressure, flow rates, and velocity

Ventilation

Ventilation is used to remove contaminants from the air and provide a healthy working environment
Types of ventilation include general ventilation, dilution ventilation, and local (exhaust) ventilation
General concepts of ventilation include calculating volumetric air flow, static pressure, velocity pressure, and total pressure
Principles of air movement include contaminant generation, purge rates, and steady-state concentration
Local exhaust ventilation includes canopy hoods, down draft hoods, enclosure hoods, and receiving hoods
Ventilation measurement equipment includes pitot tubes, rotating vane anemometers, and thermal anemometers
Key information to remember on ventilation includes understanding types, concepts, and measurement equipment

Accident Causation and Investigation Techniques

Domino Theory suggests that a series of events can lead to an accident
Heinrich's Axioms of Industrial Safety state that accidents are preventable and that safety is a line responsibility
Human Factors Theory suggests that human error is a major contributor to accidents
Accident and Incident Theory includes the epidemiological theory, systems theory, energy release theory, and behavior theory
The Modern Causation Model includes operating errors, systems defects, command errors, safety program defects, and safety management errors
Seven Avenues include safety management error countermeasures, safety program defect countermeasures, and command error defect countermeasures
Accident investigation procedures include purpose, investigation procedures, fact-finding, and interviews
Problem-solving techniques include the scientific method, gross hazard analysis, job safety analysis, and failure modes and effects analysis
Key information to remember on accident causation and investigation techniques includes understanding theories, models, and procedures.
