We know that _______ is the leading cause of injuries (and deaths) at incidents.
overexertion
Efforts to improve an individual’s strength, flexibility, and aerobics to help prevent overexertion at incidents cane defined as ________.
work hardening
Work hardening is an important part of overexertion resistance, as is efficient _________.
fueling
The three stressors that influence overexertion are related to the ___________, ___________, and the quality of _________.
environment
human physiology
rehab efforts
Some define _______ as 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
The relationship of the worker to the setting has to do with ________ that are being employed.
body mechanics
The _________ strategy acknowledges that the workers are less apt to suffer an injury if they are aware of the problem.
awareness
_______ is 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
_______ can be defined as an individual’s gradual process of becoming accustomed to an environment.
Acclimation
The primary mechanism to prevent heat stress is ___________.
sweating
_________ includes the use of shade, air movement, and rest to bring down core temperatures.
Passive Cooling
________ is the process of using external methods or devices to reduce elevated body core temperatures.
Active cooling
Active cooling is best achieved using a ________ technique or the use of cold, wet towels on the head and neck.
forearm immersion
Exposure time to frostbite is based on ____________.
uncovered, dry skin
The prevention of thermal stress injuries can be accomplished through ___________, __________ and __________.
