Workplace Controls for Health Hazards
Discuss why you believe a general ventilation system is appropriate for this operation.
-State where you would you place the fans associated with the ventilation system.
-Explain how you would test the effectiveness of the ventilation system.
For the local exhaust ventilation systems:
-Describe the local exhaust ventilations (LEVs) you would use for each area (paint booths and hand-welding stations).
-Choose a hood type for each of the two LEVs.
-Calculate the flow rate that would be required if you placed the LEV for the welding operation 24 in. from the weld and desired a capture velocity of 100 ft per minute (ft/min) given W=12 in. and L=24 in. for any of the three hood types.
Discuss any barriers you might face in implementing the use of the LEVs for these two operations.
Part II: You also determined that engineering controls are needed for the hydraulic press area.
-Discuss some types of engineering controls that might be implemented for the hydraulic press area.
-Describe the information you might require prior to designing engineering controls for the hydraulic press area.
-Explain how you would evaluate the effectiveness of the engineering controls for this area.
