8- Self test questions Flashcards
Define a work-related musculoskeletal disorder.
Disorders of the musculoskeletal system that have developed gradually over time, and which can be
attributed, either completely or in part, to a person’s occupation and related workplace conditions.
Ergonomic risk factors include what type of hazards?
Vibration, repetition, awkward and/or static postures, forceful exertion and heavy lifting, contact stress,
and temperature.
What questions should you ask while gathering information for an ergonomic assessment?
How many workers are employed in each job? What are the characteristics of the workforce (e.g.,
gender, age, etc.)? What are the primary tasks involved in each job? What is the established work rate and how is it determined? What opportunities are there for workers to rotate to other jobs? How many
hours do employees work each week, is the work organized into shifts, and how much overtime (if
any) is required?
How can you help determine if fatigue influences the way work is performed?
By visiting the shop at different times during the day.
List some examples of engineering controls that you might recommend for ergonomic
hazards.
Change the transportation methods, change the process or product, modify containers or parts
presentation for easier reach, and change the workstation layout.
What are some benefits of administrative controls?
They can be implemented quickly, often at low cost, making them useful as temporary measures while
awaiting engineering control implementation. They can be implemented when engineering controls
may not be possible or practical. The education and training continue to be beneficial to workers even
after an engineering control has been implemented.
What types of long-term indicators can be used to determine control effectiveness?
Reductions of musculoskeletal disorder the incidence rates, severity rates, job turnover or absenteeism,
workers compensation claims, workers complaints of discomfort, and an increase in productivity of the
quality products and services.
List the signs and symptoms of heat illness.
(1) Dizziness or confusion.
(2) Nausea or vomiting.
(3) Staggering.
(4) Disturbed vision.
(5) Confusion, collapse or loss of consciousness.
What is the most serious heat-related disorder?
Heat stroke.
List the work-related risk factors to consider when accomplishing a heat stress evaluation.
Hot environments, high work demands, and protective clothing requirements.
What climatic factors influence the rate of heat exchange between a person and the
environment?
Air temperature and air speed.
What are the physiological responses to cold stress?
The first physiological response to cold stress is to conserve body heat by reducing blood circulation to
the skin; the second physiological response is shivering, which increases the rate of metabolism.
At what outside daily high temperature are WBGT measurements taken and how often?
At 85 °F, WBGT measurements are to be taken a minimum of four times, evenly spaced, during the
hottest part of the day.
What offices/personnel are involved in determining the FITS zones and notifying the
aircrews?
Meteorological/weather staffs, BE personnel, and squadron operations flights.
Who approves and authorizes unit commanders to reduce the MOPP level?
The senior AF commander.
