Safety Evaluation and Control Summary

1. Determine the hazards that may be present from this list of energy sources.
2. Pressure Sources 

   Electrical Sources	Chemical Sources	Motion Sources	Heat Sources
   Capacitors	Corrosive materials	Pulley, belts, gears	Electrical
   Transformers	Flammable materials	Shears, sharp edges, pinch points	Steam
   Batteries	Toxic materials	Vehicles	Flames
   Exposed conductors	Radioactive materials	Mass in motion	Solar
   Static electricity	Pathogenic microorganisms		Friction
   Other high-voltage sources	Oxygen deficiency		Chemical reaction
   	Carcinogenic materials		Spontaneous combustion
   Gravity-Mass Sources	Cold Sources	Pressure Sources	Radiant Sources
   Falling	Cryogenic materials	Confined gases	Intense light
   Falling objects	Ice, snow, wind, rain	Explosives	Lasers
   Lifting		Noise	Ultraviolet (UV)
   Tripping, slipping		Chemical reactions	X rays and ionizing radiation
   		Stressed mechanical systems	Infrared sources
   			Electron beams
   			Magnetic fields
   			RF fields
   			Nuclear criticality (neutrons)

    

3. Consider how the employee and the energy sources might interact under the following situations:
   • Hardware being used incorrectly.
   • Personnel taking shortcuts to avoid arduous, lengthy, or unintelligible procedures.
   • Equipment that is difficult to maintain suffering from lack of maintenance.
   • Special training instructions being forgotten.
   • Written procedures that are confusing, lengthy, or poorly written and/or being ignored.
   • Personnel being distracted by stress, fatigue, inattention, illness, personal problems, etc.
   • People with varying experience being assigned to do the work.
4. Consider the severity of the accidents that could occur and how frequently they might happen (the risks associated with the hazards).
5. List the hazards found in the operation; those with the highest risk should be listed first.
6. Make a decision: Which hazards can be TOLERATED? Which hazards must be TERMINATED, TRANSFERRED, or TREATED?
7. After considering both cost and effectiveness, develop control criteria for those hazards that cannot be tolerated (the most effective control type is listed first):
   • Controls that can be designed to function as part of the hardware. (Engineering Control)
   • Personal protective equipment. (PPE Control)
   • Warning signs and devices. (Administrative Control)
   • Procedures and specialized training. (Administrative Control)
8. Consider the acceptability of the residual risks and obtain management approval as necessary.
9. Implement the control criteria developed.
