ASP 25 Flashcards
1. Epicondylitis ("Tennis Elbow")
1. Caused by jerky, throwing motions
2. Tendons on outside elbow injured or strained
2. Nomenclature
Nomenclature is a system of names or terms, or the rules for forming these terms in a particular field of arts or sciences. The principles of naming vary from the relatively informal conventions of everyday speech to the internationally agreed principles, rules and recommendations that govern the formation and use of the specialist terminology used in scientific and any other disciplines.
3. state of matter
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma.
4. Neutron degeneracy
Neutron degeneracy is analogous to electron degeneracy and is demonstrated in neutron stars, which are partially supported by the pressure from a degenerate neutron gas
5. Matter waves
Matter waves are a central part of the theory of quantum mechanics, being an example of wave–particle duality. All matter exhibits wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave. In most cases, however, the wavelength is too small to have a practical impact on day-to-day activities.
6. Tendinitis
Inflammation of tendons associated with repeated moving, bending
7. Trigger Finger
Finger movement not smooth - snaps or jerks
8. White Finger
- Insufficient blood supply causes fingers to become pale
- Arteries closed due to vasospasms triggered by VIBRATIONS
- Working in the cold, working with jackhammers, etc
9. Ergonomics Program Steps/Factors
- All personnel represented on ergo team (labour, management, engineering, safety)
- Training
- Identifying existing or potential problems
- Evaluate risk factors
- Design and implement
- Monitor Effectiveness of corrections
10. Workstation Design (10 Factors)
1. Ensure PROPER MATCH between facility and operator
2. Task design and work DESIGN INTERRELATED
- Forces kept to less than 30% of maximal forces
- Up to 50% acceptable for short durations
- Static forces kept to less than 15% of maximal forces
3. Use best MECHANICAL ADVANTAGE
4. Foot controls OK for seated workers NOT for standing workers
5. Maintain proper SITTING HEIGHT
6. Permit CHANGE of POSTURE
7. Accommodate LARGE OPERATORS in design
8. BENCH Height
- Sitting 50cm - 70cm
- Standing 89cm
9. Controls and computer screens placed in VISUAL FIELD
10 INSTRUCT and TRAIN operators to use good working posture
11. Standing Work Heights (Delicate, Light, Heavy)
Delicate work - 2"-4" above elbow
- Light work - 2"-4" below elbow
- Heavy work - 6"-16" below elbow
12. REBA (Rapid Entire Body Assessment) (Bag it, tag it) Steps
- Looks at entire body as you do a task
- Steps
1. Observe the task
2. Fill out a checklist
3. Compute Scores
4. Compare
5. Interview and Observation
- Based on
- The most difficult postures and work tasks
- Posture sustained for longest period of time
- Posture where highest workloads occur
13. RULA (Rapid Upper Limb Assessment)
Rapid Upper Limb Assessment (RULA) is a survey method developed for use in ergonomic investigations of workplaces where work related upper limb disorders are reported. RULA is a screening tool that assesses biomechanical and postural loading on the whole body with particular attention to the neck, trunk and upper limbs. Very similar to REBA - see REBA for steps
14. REBA/RULA Pros/Cons
Pros:
- User Friendly
- Advanced Degrees/special equipment not required
Cons:
- Does not consider duration of task
- Only allows for looking at one point in time or worst-case scenario
- Must use representative postures
15. System Safety
- Systematic approach to detect deficiencies in system components
- Incorporate safety devices
- Provide warnings
- Develop procedures/training
16. System Safety Analysis (What-if, HAZOP)
- What-if Analysis: INFORMAL investigation introducing and evaluating hypotheticals
- Haz-OP: FORMAL study examining potential deviations from design conditions that could create problems/hazards
- Both frequently a TEAM EFFORT
17. FMEA (analysis)
- Failure Mode and Effects Analysis
- Looks to potential equipment failures - traced to predict effects
- Analysis leads to critical items list: What are the worst hazards? How to prioritize?
18. STEP analysis
- Simultaneous Timed Events Plotting
- Looks at events from time or sequence perspective
19. MORT
- Management Oversight and Risk Tree
- Identifies risks and refers to proper management
20. the unit of measurement of momentum
In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.
21. quantum field theory
In quantum field theory, correlation functions, often referred to as correlators or Green's functions, are vacuum expectation values of time-ordered products of field operators.
22. An electromagnetic field
An electromagnetic field (also EM field or EMF) is a classical (i.e. non-quantum) field produced by moving electric charges.[1] It is the field described by classical electrodynamics (a classical field theory) and is the classical counterpart to the quantized electromagnetic field tensor in quantum electrodynamics (a quantum field theory).
23. quantum vacuum state
In quantum field theory, the quantum vacuum state (also called the quantum vacuum or vacuum state) is the quantum state with the lowest possible energy.
24. Energy Trace and Barrier Analysis (Part of MORT)
- Incident: unwanted energy flow from inadequate barriers resulting WITHOUT adverse consequences
- Accident: Same but WITH adverse consequences
25. Fault Tree Analysis - Event Types
- Four Event Types:
- Fault Event: Rectangle
- Basic Event: Circle
- Undeveloped Event: Diamond
- Normal Event: House Shape - probability close to 1
