Ch9 Flashcards
More often than not, ________causes mental and physical mistakes.
Overexertion
We know that _______is the leading cause of injuries and deaths at incidents.
Overexertion
The essence of fire service professionalism is the ability to function _____ at all times.
Safely
The number one cause of injuries?
Overexertion
Efforts to improve an individuals strength, flexibility, and aerobics to help prevent overexertion can be defined as?
Work hardening
The science of adapting work or working conditions to a worker. Others define it as the study of problems associated with people adjusting to their work environment
Ergonomics
Physical setting + Worker relationship to setting + Task requirements = ?
Ergonomic stress
Worker relationship to the setting:
Often the speed or pace at which the task is completed may also create an __________.
Injury relationship
Task requirements:
In other cases, the limited number of people(staffing) available to accomplish the task is the primary factor leading to ______.
Injury
Physical setting:
Understanding the stressors related to the physical setting involves examining the surface conditions of the working area.
Distractions are also part of the work setting.
Often, The setting stressor has to do with the space size or geometry of the work location.
Key information
Ergonomic abatement strategies:(3)
Awareness
Accomodation
Acclimation
Perhaps the most used abatement strategy and certainly the most simple.
Awareness
______includes efforts to alter or adjust the environment, worker relationship, or task to reduce injury potential
Accommodation
Abatement strategies:
The use of PPE is ?
Accomodation
Can be defined as an individuals gradual process of becoming accustomed to an environment
Acclimation
Abatement strategies:
The most difficult stategy to implement during an incident. Most is done proactively and is typically gradual
Acclimation
The primary mechanism to prevent heat stress is _______.
Sweating.
Evaporative cooling
FFs engaged in operations wearing full structural PPE will have elevated core temperatures, averaging over _______ after 20 minutes(one scba bottle) of activity.
101.5
An early warning sign that the core temperature is elevated.
THF
Transient heat fatigue
____ is a signal that active core cooling remedies are needed
THF
Characterized by the onset of physical exhaustion that is remedied by rest and hydration only to return quickly and more profoundly upon engagement with the hit environment
THF
Thermal radiation from flames and hot surfaces is the most common cause of THF.
True or false?
True
Characterized by blotches of red skin or red bumps, especially around the neck, cheeks, underarms, and groin
Heat rash
- another sign that active cooling remedies are needed
True injury marked by muscle spasms. A warning that the body’s electrolytes are not balanced. Medical attention is warranted.
Heat cramps
- dehydration may also play a role in heat cramps
Actually an early form of hypovolemic shock due to the loss of water and electrolytes through sweating.
Heat exhaustion
Characterized by cool and clammy skin that may be ashen gray and may be accompanied by dizziness, nausea, and or headaches. Medical attention is warranted.
Heat exhaustion
The most serious heat stress injury
Heat stroke
Result of the failure of the bodies cooling mechanisms. Characterized by a change in behavior and in some cases, hot, dry, flushed skin(late sign)
Heat stroke
_____is considered a medical emergency and rapid transport to hospital is mandatory
Heat stroke
The prevention of thermal stress injuries can be accomplished by ______,_________, and __________.
Accomodation, rotation, and hydration
