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

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
