Unqualified Person Electrocution: most frequent causes of occupational - People who are not trained or still being trained injury Electricity travels in closed circuits How to Protect from Electricity Body can be a conductor which mean electric shock 1. Follow specialized Procedures The effect of electricity depends on the milliamperes 2. Use lockout/tagout 3. Conduct inspection 4. Follow assured grounding programs 5. Use GFCIs 6. Guard energized parts Assured Grounding Program - Written program, daily visual inspection, and method to detect a faulty grounding wire - Grounding gives a stray current somewhere to go. Effects on human body Severity of shock depends on: Fall Protection ○ Path of current - Fall is one of the most common causes of injury ○ Amount of current - Employers must set up the workplace to prevent ○ Length of time the body is in circuit employees from falling Types of injuries To prevent employees from being injured: Guard every floor hole using a railing and toe-board Direct Indirect or a floor hole cover 1. Electrocution 1. Falls Provide a guard rail and toe-board around every 2. Electrical shock elevated open sided platform, floor or runway. 3. Burns Safety harness and line, safety nets, stair railings and 4. Arc blasts handrails. Fall protection plan Causes 1. Identify hazards 1. Improper Grounding 2. Prevent hazard 2.

Fuel- combines with oxygen in the presence of safety of their workers heat (without this nothing to burn) - Industrial hygiene is the science dedicated to the 2. Heat- accelerates the combining of oxygen and anticipation, recognition, evaluation, fuel (not sufficient then no ignition) communication, and control of environmental 3. Oxygen- element that combines chemically with stressors in the workplace that may result in injury, another substance through the process of illness, impairment, or otherwise affect the oxidation (without this fire cannot begin) wellbeing of workers and community members - Performing maintenance on aircraft uses Key Components of Industrial Hygiene electrical tools that can produce spark as a result 1. Ergonomics - reduces stress and eliminate injuries a high potential for fire to occur associated with bad posture - Know what the caused the fire, how to prevent it, and how to put it out 2. Noise- long term exposure can lead to hearing loss Classification of Fire 3. Temperature- if temp is too high (heat stroke), temp Never fight fire if: too low can also cause problems - You don't know the material, what type of extinguisher to use, and how to use it 4. Indoor Air Quality- can be impacted by pollution, - The fire is spreading beyond where it started machines and more - Your instinct tell you not to 5. Chemical Exposure- take many forms and can be Pull the fire alarm, evaluate the area and call fire absorbed, inhaled, or ingested department Know PASS (Pull, Aim, Squeeze, Sweep) 6. Radiation a. Non ionizing- UV and laser radiation can cause burns Class Material b. Ionizing- more harmful and can be found in A Ordinary combustibles like paper, wood health care facilities or nuclear factories B Flammable Liquids 7. Biological Hazards- living organisms inside a human body and can cause acute and chronic infections. C Energized (Live) Electrical Equipment People who work with plants/ animals and laboratory are at risk D Combustible Metals like magnesium, sodium 8. Eliminating or Controlling Hazards- starts with K Combustible cooking oils/fats in cooking designing the hazard out of the process or operation appliance providing safety measures Types of Fire Extinguisher Fire Safety Fire Prevention 1. Understand the elements need to be there for fire to exist (Heat, oxygen, Fuel) 2. Good Housekeeping
