Push-back combines the density of drive-in rack with the selectivity of single selective pallet rack using a series of mobile carts that ride on rails within each row. A loaded pallet is placed on the upper cart within the system. As the next pallet is loaded, the forklift gently pushes the first pallet load back, exposing the 2nd cart. The process continues until all carts are used (typically 3-4 deep), with the last pallet resting on the rails. As each pallet is extracted the subsequent pallet flows to the aisle face for selection, allowing for highly productive pallet retrieval.
Push-back is a last-in/first out (LIFO) storage solution and not appropriate for items with expiration dates. Additional vertical clearance is needed per level to accommodate stacked carts which may limit the number of vertical positions available.
Advantages | Considerations:
- High density system
- Requires limited number of aisles
- Ideal for high-volume, low-SKU applications
- LIFO stock rotation – drive-in
- FIFO stock rotation – drive-through
- Systems can be underutilized as SKUs increase (honeycombing)
Violence in the workplace often erupts without warning, and can have tragic results. Taking steps to prevent these situations can improve safety in your workplace, improve employee satisfaction and lead to increased productivity. Conversely, ignoring potential hazards can result in employee injury, even death — and legal action at considerable costs to the company.
OSHA has outlined five steps you can take to identify and prevent these violent encounters before they happen. While they are not directly related to materials handling operations, we feel these guidelines can apply to a wide variety of organizations, including your company.
Management Commitment and Employee Participation
As with any initiative, without the commitment of management and leadership, the rank-and-file of the organization will likely ignore any efforts to improve safety with regards to violence. Company leadership must be involved on a regular basis and visibly endorse the effort. This can be achieved by establishing a safety and health committee, and having leadership rotate in and out of meetings conducted by the committee.
Management must articulate a policy and establish goals for the company. Once a plan has been developed, leadership should allocate sufficient resources to accomplish the goals and uphold program performance expectations. Providing resources could entail meetings with health professionals to help identify potential hazards, creating visible signage and using other communication methods to keep workers involved in and aware of the program.
Worksite Analysis and Hazard Identification
There are probably facets of your operation that are prone to producing higher anxiety or tension among your employees. These could be actual physical conditions such as heat, cold, and hazardous areas as well as departments that demand high productivity, or even interaction with the public. Taking stock of these areas and identifying factors that are the least or most likely to create a stressful atmosphere are key to prevention. Two steps you can take to identify and prevent violence include:
- Conducting job hazard analysis – Management can conduct surveys of their departments to assess the potential risk of violence among employees. This not only includes internal assessments, but assessments of destinations to which your employees may travel, including specific neighborhoods, time of day, etc. Sites that expose your employees to violent behavior are often outside the walls of your facility.
- Conduct employee surveys – Employees will often tell you if their jobs create stressful situations for them and if they feel endangered by some of their job tasks. Conduction of reviews on a regular basis will help you identify these areas and create a plan to reduce danger.
Hazard Prevention and Control
Once management has established and articulated its commitment, and evaluations have taken place, a plan to reduce potential hazards must be implemented. This step includes:
- Identification and evaluation of control options for workplace hazards
- Selection of effective and feasible controls to eliminate or reduce hazards
- Implementation of these controls
- Follow up to confirm these controls are being used and maintained
- Evaluate effectiveness and improve, expand or update these controls as needed
Safety and Health Training
As with any program you want to succeed, employees must be trained in order to follow the steps outlined by the company to identify and report these risks and follow up as needed.
This training could include meetings with mental health experts to help identify signs of stress in colleagues that could lead to violence. It also can include training on how to avoid violence outside your facility by taking common-sense actions (such as parking under a street lamp), what to do if an employee feels threatened and even self-defense training. Other training topics can include:
- The company’s workplace policy on violence prevention
- Documentation and reporting
- Location, operation and coverage of safety devices such as alarms
- Ways to identify and deal with hostile situations
- A standard response plan for violent situations
Recordkeeping and Program Evaluation
Recordkeeping includes reporting procedures, what gets reported and to whom, and how these records are kept. Keeping track of both “close calls” and actual events helps you identify patterns, areas of particular concern and even certain job functions that might be creating undue stress on employees. It can help you identify areas outside your facility that present a danger to your employees, such as areas of town they serve.
OSHA Log of Work-Related Injuries and Illnesses (OSHA Form 300) can help you organize information not only for reporting to your proper internal sources but also for reporting to OSHA if necessary. As of January 2015, all employers must report:
- All work-related fatalities within 8 hours
- All work-related inpatient hospitalizations, all amputations and all losses of an eye within 24 hours
Injuries sustained as a result of assault must be entered on the log if they meet OSHA’s recording criteria (CFR Part 1904, revised 2014).
Keeping track helps you improve your program, improve employee safety and ensure your employees are operating in a safe and productive work environment.
We hope this summary is helpful to you in establishing your own workplace violence prevention plan.

While it was prepared for healthcare and social service workers, the overall content of this guide can assist any company, big or small, in achieving a safer work environment for all.
