What conditions cause on the job stress ○ Sources of workplace stress include environmental conditions, work overload, role ambiguity, lack of feedback, personality, personal and family problems, and role conflict. Other sources of workplace stress are task complexity, lack of control over the job, public safety responsibility, job security, lack of psychological support, and environmental safety concerns.  2. What is best policy regarding stress ○ The best policy regarding stress is to learn to adapt to it.  3. Concept of risk assessment ○ The process of quantifying the level of risk associated with the operation of a given machine or process ○ Decision Tree; asks 4 questions ■ Severity of potential injuries ■ Frequency of exposure to potential hazards ■ Possibility of avoiding the hazard if it does occur ■ Likelihood that the hazard will occur  4. What type of machine guard shuts machine down when access doors are not in place ○ Interlock  5. Best guard for robots ○ The best safeguard for a robot is a barrier around the perimeter of its work envelope. Sensitized doors or gates in the barrier can also decrease the hazard potential.  6. Categories of surface falls ○ Most falls fit into one of four categories: trip and fall, stumble and fall, step and fall, and slip and fall.  7. Primary causes of falls ○ The primary causes of falls are a foreign object on the walking surface; a design flaw in the walking surface, a slippery surface, and a person's impaired physical condition.

 8. 40% of injuries in the first year of employment are back related  9. What force hard hats are tested in foot lbs. ○ Hard hats are tested to withstand 40 ft lbs of impact  10. What elements slip and fall prevention programs should include ○ A slip and fall prevention program should have the following components: policy statement commitment; review and acceptance of walkways; reconditioning and retrofitting; maintenance standards and procedures; inspection, audits, tests, and records; employee footwear; legal defenses; and measurement of results.  11. Difference between heat stroke and exhaustion ○ Heat exhaustion is a condition whose symptoms may include heavy sweating and a rapid pulse, a result of your body overheating. ○ Heatstroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious form of heat injury, heat stroke, can occur if your body temperature rises to 104 F (40 C) or higher.  12. Know net heat load  ○ When body cannot compensate by sweating, its net heat load is exceeded  13. Critical burns ○ Third Degree ■ Penetrate inner layer of skin. Scars 1. Minor: 2% BSA (Burn Surface Area) 2. Moderate: 2-10% BSA 3. Critical: 10% and up BSA  14. Second degree burns (how much % of body has to be covered) ○ First Degree ■ Minor Burns ○ Second Degree ■ Up to 210 F, Blisters 1. Minor:0-15% BSA 2. Moderate: 15-30% BSA 3. Critical: 30% and up BSA   15. What safety hazards associated with pressurized boilers

Safety hazards which are associated with pressurized boilers include all of the following except: Operator training ○ Design construction installation errors, poor operator training, human error, mechanical failure, insufficient inspection, improper application of equipment, insufficient preventative maintenance 16. The best ways to promote safety program ○ Incentive programs ○ Encourage Safety ○ Rewarding ○

 17. Know situations that cause vacuum ○ A vacuum (negative pressure) is caused by pressures below atmospheric level. ■ May be a result from hurricanes or tornadoes  18. Greatest danger to electrical shock ○ Current  19. Know safety device used to detect the current of ground to open circuit ○ Ground Fault (Circuit) Interrupter - GF(C)I  20.Flash point for flammable liquids ○ Flammable liquids have a flash point below 100ºF.  21. 3 elements to sustain fire ○ Oxygen ○ Fuel ○ Heat  22. Fire classifications related to nature of the fuel ○ Metal fire, inorganic matter fire ○ Class A fires involve solid fuels. ○

■ Wood, coal Class B fires involves flammable liquids and gases.

○

■ Oil, gasoline Class C fires involve live electricity.

○

■ Short circuits, wires Class D fires involve combustible metals. ■

Sodium, potassium, uranium

 23. Carbon Monoxide Gas

○

A colorless, odorless, deadly gas - the result of incomplete combustion of a fuel. Produced when there is insufficient oxygen

○  24.Toxic effects are a function of: a. Properties of the substance b. Amount of the dose c. Level of exposure d. Route of entry ← this was bold in the book e. Resistance of the individual substance 

25. Max allowable rems (radiation unit) per quarter ○ During any calendar quarter, the dose to the whole body does not exceed 11/4 1.25 rems  26.How many days employers have to follow up with written report after radiation incident occurs ○ Within 30 days  27. Let go current for average person in milliamps ○ Women - 6 milliamps ○ Men - 9 milliamps  28.Definition of confined spaces: ○ Any area with limited means of entry and exit that is large enough for a person to fit into but is not designed for occupancy  29.What agency helps OSHA with radiation regulation ○ Nuclear Regulatory Commission (NRC)  30. Categories of radiation hazards are (particles) ○ Ionoizing ■ radiation that becomes electrically charged or changed into ions. ○ Non-ionizing ■ is that radiation on the electromagnetic spectrum that has a frequency (hertz, cycles per second) of 1015 or less and a wavelength in meters of 3 Hz 10–7 or less. This encompasses visible, ultraviolet, infrared, microwave, radio, and alternating current (AC) power frequencies. Radiation at these frequency levels does not have sufficient energy to shatter atoms and ionize them.22 However, such radiation can cause blisters and blindness. 31. Toxic Substances:
