Injury Flashcards
Injury vs. Accident
I: PREVENTABLE
A: implies that it can’t be prevented… we don’t use this word
Injury:
physical damage due to exposure to an energy agent or lost of an essential agent (usually oxygen-suffocation/drowning)
Kenetic Mechanical Thermal Chem Radiation Electrical
Intentional vs. Unintentional nrg
Intentional: suicide, homicide, assult
Unintentional: Car crash, alls
Kinetic nrg
motor vehicles, bullets
potential nrg
fals
mechanical nrg
dog bite, chain saw injury
chemical nrg
poisoning
lack of oxygen
suffocation, drowning, sewage workers
NIOSH…is injury work related?
If injury occurs in work activity/training
YES
NIOSH…is injury work related?
If you’re on break?
YES…unless you’re eating, applying cosmetics
NIOSH…is injury work related?
If you’re in the parking lot?
yes! if youre going to/leaving work

NO
NIOSH…is injury work related?
if you’re just a visitor
NO
NIOSH…is injury work related?
If you’re commuting to work?
NO

if your job is a “homemaker”
no… not a real job

If you’re working for pay at home
yes
NIOSH…is injury work related?
Working in family profit-oriented buisness
yes
if family members are EMPLOYED… farmers make sure all family is employed

Yes
commuting
no
NIOSH…is injury work related?

no
fired
NIOSH…is injury work related?

yes
NIOSH…is injury work related?
student engaged in school activities?
only if you work for school
An injury is work related IF
- Person injured while engaged in work activity
- injury occurs to worker at work location…even if on break!!!
Leading CODs in US
#1: Heart disease #2 Cancer #3 Stroke #4 UNINTENTIONAL INJURIES ...leading in people under 24
deaths and disabilities due to injjury
90K deaths a year
19M disabling injuries a year
Firearm deaths on the rise hugely
what do we need to consider a public health issue?
car crashes
cost estimate per year due to injuries
$400 billion per year
direct medical costs for ex
Injury Direct costs
$51 billion for ALL injuries in 1992
$55 billion in 20122 JUST FOR THE TOP 10
Industrial death rates per 100K people
30% Ag and logging 18% mining 15% transportation, warehousing 10% construction 2.5% manufacturing 2.6% Other Services

Heinrich’s Domino Theory (1931)
Change the behavior, but blame the worker
for each major reported injury: 29 minor, 300 incidents with no injury
unsafe acts by worker account for 90%
injuries usually caused by a single event
Energy Exchange Concept:
Dehaven (1942) and Gibson (1961) control nrg transfer, engineering control five basic nrg forms -mechanical/kinetic -chemical -thermal -electrical -radiation
Community Injuries: Car Crashes
33,000 deaths/year
death per 1M miles has dropped due to engineering changes
2M bad injuries per year (.5 of all brain damages)
Costs about 99Bill a year
Car Crashes…what is the exposure?
whenever you get into a vehicle
this the the DENOMINATOR
Why have the trends in vehicle crashes changed?
increased with increase of # of cars
people died from being thrown from vehicles
60’s: seat belt and replace metal with plastic
Control Strategies
Safety rating systems for cars Ergonomics: design and system layout Protection of occupants:airbags Control to allow for human error: antilock breaks, stability control Better emergency treatment: jaws of life
important things to remember with cars…
MASS of vehicle… whoever is in the lighter car is in more trouble :(
Injuries of children
#1 COD is trauma (all under 24) 44% of trauma deaths occur in 1-14 yr olds
we spend on childhood disease…but not childhood injury
lack of data and control strategies
Fires
More smoke alarms and firefighters… death rate from fires 1.5-3X higher than other countires
why is our fire death rate higher
we don’t make sure that our fire detectors work
we have improved fire codes…but that only applies to new buildings
Residential Fires
85% all fire deaths in US 66% of fire related injuries 50% property loss leading causes: cooking and bad heating systems Leading cause of fire deaths: smoking!
Leading cause of fire
ARSON
three major risk factors associated with fire deaths
- poverty: older houses, no batteries in fire alarms
- cigarettes
- alcohol
injury rates in workers…
120 mill workers…usually females, usually older
LESS manufacturing, more services… so we have more high tech and toxicity injuries
10 leading injuries in the workplace
#1 Over exertion #2 slipping/tripping #3 Falling from Heights #4 Reaction Injuries #5 Falling Object injuries #6 "Walking into" injuries #7 Vehcile Accidents #8 Machiene Entanglement #9 Repetitive motion #10 on the job VIOLENCE
injury rate in workplace…
more people working, more injuries
rate may not change
