FIVE STEPS OF RISK MANAGMENT?
Identify Assess Describe Implement Monitor and review
TWO MAIN TYPES OF HAZARDS?
Health
Safety
5 TYPES OF HEALTH HAZARDS?
Chemical Biological Physical agents Work design Workplace stress
PRODUCTS OF HEALTH HAZARDS?
Long term (chronic) problems
Occupational Illnesses
- exposure to chemicals, biological substances, or physical agent or other stressor that can harm them
SAFETY HAZARDS
A safety hazard is anything that can cause a physical injury
Safety hazards cause harm when hazard controls are not adequate
WHAT ARE THE DIFFERENCES BETWEEN HAZARDS AND RISKS?
- a hazard is something with the potential to do harm
- risk is the likelihood that death, injury or illness may result because of the hazard
WHAT ARE THE TWO MAJOR FACTORS TO CONSIDER WHEN ASSESSING THE RISK HAZARDS?
- likelihood of an incident occurring
- consequences
FOUR MAIN DIVISIONS OF INCIDENT LIKELIHOOD?
- high frequency/ high risk
- high frequency/ low risk
- low frequency / high risk
- low frequency / low risk

CONSEQUENCES OF HAZARDS?
EXTREME- death or permanent injuries
MAJOR- serious bodily harm
MODERATE- casualty treatment
MINOR- first aid only, no loss of work time
HI LIFT JACKS
Can lift , pull, or push 4,500 to 8,000 lbs
From base to mid shaft is most stable
Should be considered as secondary stabilization device, not primary
COMMON USE OF TORCHES
Cutting
Heating
Soldering
Brazing
Welding
Stress relieving
Flame hardening
ACETYLENE
- made of hydrogen and carbon
- member of the hydrocarbon gases
- explosive range of 3.0 - 93%
- requires only 10% O2 to ignite
- burning temp of 4600-5700 F WHEN BURNING WITH O2
- auto ignition temp is 763-824 F
- if gas reaches 30 psi in free state it can explode by itself without a spark or flame present
Type A bus
- limited passenger
- no special exit doors
- MUST have seat belts
Type B bus
- 22 passengers
- rear exit doors
- side window emergency escape
- may have seat belts
- engine in front of steering wheel
Type C bus
- up to 70 passenger
- emergency exit in rear and side door , some windows and roof
- probably no seat belts
- engine in front of window
Type D bus
- up to 70 passenger
- super D over 100 passengers
- rear engine
- emergency exits on side and roof NOT IN BACK
- narrow isles (12 to 15) in.
Transit buses
- few seats mostly standing
- up to 120 passengers
- both exits on passenger side
- large windshield
- large windows with emergency exits
- handicap accessible
Thomas bus
- few rivets
- adhesive used
- metal will tear before joints give way
- if heated, glue will fail
Bus incident phases
- size up
- pre-arrival size up
- special considerations
- treatment and or transport of under age victims
- policy per AHJ/ medical control required
- termination
Center of gravity
The point where all parts balance one another
Stability baselines
Imaginary lines drawn between points where tractor tires contact the ground
Centrifugal force
The outward force nature exerts on objects moving in a circular fashion
Size up
- number of vehicles
- type of bus
- point of contact
- position of bus
- bus hazards
- additional hazards
- inner/outer survey
Pre-arrival survey
- time of day
- day of week
- weather
- crowd control
- number of patients
- age of patients
- locations
Special considerations
- additional ambulances
- additional manpower
- parental control
- school notifications
- age of victims
- hospital communications
