Midterm Part 2
The shipping and cold storage room at Pick 'n Pay Produce (fruit and vegetables) warehouse is a busy place. Twelve-foot vertical racks in the cold storage room hold multiple pallets. Some of the fruit is tightly packed and overripe. The boxes are heavy and sometimes damp. Electric forklifts move pallets from place to place, including an outdoor dock where transportation trucks are loaded all year round by the forklifts.
The manager is giving a tour of the area to the boss’s nephew who will be working there for the summer. The manager wants to impress upon the young man that this is serious work with a variety of hazards.
• What four major safety and health (including ergonomic) hazards can you identify and control? For each of these four, identify their potential impact on worker health and safety and some ways to control the hazard. [HINT: See grading rubric below.]
• Using the scenario above, select two categorically different hazards or potential hazards that you identified in part (A) and answer the following for each of the two distinct hazards. [HINT: See grading rubric below.]
• Identify at least one OSHA standard for each hazard that would reduce the hazard
• Cite the standard as "29 CFR 1910.x, Name of Standard"
• Analyze the major requirements of the standard as they address the hazard
• How would implementing any of those requirements reduce or eliminate the hazard?
• Is implementing an OSHA requirement sufficient to ensure worker safety? Why or why not?
