5S. Kaizen management methodology. Workplace organization method that uses a list of five words.

Enhancing Workplace Safety with 5S

5S is lean Six Sigma approach designed to reduce waste and maximize productivity by keeping an orderly workplace and achieving consistent results that can be checked via visual cues. Implementation organizes the workplace within its existing framework, and this is the first step toward a lean Six Sigma effort. However, in an advanced manufacturing environment, there are many benefits to adopting these practices outside the formal Six Sigma system.

Benefits of 5S in an Advanced Manufacturing Environment

Developing consistency and organization leads to a conscientious attitude and a safer, more efficient workplace. Conversely, when defects and waste aren’t measured and controlled, costs begin to pile up. Here are some examples:

  • Output falls short due to variations between crews.
  • Utilization is reduced due to longer-than-expected product changeovers.
  • Missing parts make it necessary to rush in a new one

Companies try to guide improvements via Six Sigma, Lean, or Total Productive Maintenance programs. However, studies show that up to two-thirds of such efforts fall below the expectations of stakeholders. Learning these methods is easy, but putting into action is not due to the following:

  • Process improvements decline.
  • Continuous improvement isn’t realized or prioritized.
  • The initiative isn’t global enough.

5S is One Solution

Companies like Danaher and Toyota went through the 5S program to develop positive cultures. 5S engages people to contribute to a visually-oriented organization, where cleanliness facilitates increased safety, productivity, and quality.

5S forms the foundation for more disciplined actions. Workers who put their tools back in place are more likely to follow production standards. Its visual nature makes it easy to spot items that are out of place. It lays the way for continuous improvement and provides:

  • Cleaner, safer work areas with fewer tripping hazards
  • Less wasted time searching for tools and materials that are more accessible
  • Unneeded items are eliminated so that less floor space is required
  • Improved self-discipline fostered by the visual nature of 5S, which makes abnormal conditions stand out
  • Improved culture due to 5S-motivated teamwork and motivation

What are the 5S’s?

The components of 5S are sorting, simplifying, systemic cleaning, standardizing and sustaining.

  • Sorting activities eliminate unnecessary items from work areas in order to clean it.
  • Simplifying arranges the work area for safety and efficiency.
  • Systematic daily inspection of facility and equipment helps determine if corrective action is needed.
  • Standardizing makes abnormal conditions stand out so that the workplace organization is sustainable.
  • Sustaining aims to keep current improvements to allow further progress to be made.

Implementing 5S

5S is not a housekeeping activity. Instead, 5S has to be a team effort and everyone should be able to tell instantly what’s out of place. With organization forming the crux of 5S, it’s vital to start with getting rid of unneeded items.

Sorting

During this phase, employees can sort and clear their work areas. This can take weeks in each department as everyone works to establish criteria for what to throw out. Much like cleaning your closet, anything not used for a year can be removed or put in a holding area. Disposing of uneeded items may mean transferring them elsewhere in the company, selling or discarding them. Then, the employee can conduct an initial cleaning.

Simplifying

Simplying gives everything a home and places each item in order of efficiency. Frequently-used items, for example, have to be close to where they’re used as possible. To accomplish this task:

  • Pick a spot for each item arranged in order of frequency of use and take safety precautions into account.
  • Label items so that there’s a home for everything.
  • Create a process to replenish supplies.
  • Document the equipment, layout and plan to replace supplies.

Systematic Cleaning

Systematic cleaning creates a document that enables inspection of the area. Everything should be swept, mopped and dusted and kept neat and clean with rags or brooms. Daily cleaning and inspections should be easy. Inspections include:

  • Identify points to check.
  • Define acceptable condition.
  • Mark equipment that has visual indicators such as gauges.
  • Conduct cleaning and visual check parameters.

Standardizing

Standardizing ensures that all workers understand the expectations.It is the workplace team that establishes the set of standards they will follow. It’s crucial that everyone has some involvement. Here are the steps to standardize the 5S processes.

  • Establish a checklist for the work area. The checklist should show everything the team checks during self-audits.
  • A multi-level audit system helps to make sure that the organization fulfills the overarching 5S goal of sustaining the work areas so that the system can evolve to more stringent controls and process improvements.
  • Establish and document a single source of truth as to the 5S processes for the company
  • Add new standards to the master document.

Sustaining

Sustaining is considered the hardest “S.” However, it shouldn’t be if you let the 5S system work for your advanced manufacturing company. At this point, you should have engaged everyone in the work area during 5S activities and have a “tell at a glance” visual workplace. If this is so, then sustaining is much easier. That is important, but not sufficient. A more systematic way to prevent backsliding and to foster continuous improvement is needed. The steps of sustaining are:

  • Define the 5S overall grade.
  • Perform routine 5S checks via the 5S checklist.
  • Address new opportunities that are uncovered during routine checks.
  • Conduct scheduled, routine checks by supervisors or someone not directly from the work area in the machine shop that is being inspected.

Perform higher-level audits to evaluate how well the 5S system is working overall. For example, are there systemic issues with sustaining 5S? Often, the company’s safety committee is an excellent body for conducting these audits.

When you develop sustaining activities everything that follows becomes part of the 5S process and future refinements. When items are returned to their place, the entire operation is smoother. When something is out of place its cause is probably that the organization needs to be tweaked so that it’s convenient. The work team should be the ones who safeguard the sustainability of 5S and improve morale, safety, and productivity.

How to Implement 5s in the Manufacturing Workplace

The efficiency and the safety of a manufacturing organization are vital for improved productivity, quality production, and profitability. The 5S is a methodology aimed at optimizing the productivity and reducing waste at the factory. It makes use of visual cues and an orderly workplace to achieve consistent results. The 5S is implemented by small teams working together to achieve a higher goal of efficiency. It can be performed in any company that does manufacturing in the USA.

Steps in 5S implementation

1. Sort

The first S deals with getting unwanted obstacles out of the way to enhance speed in the production activities. All unneeded items should be kept away and the right people allowed to do the job at hand. In essence, the production workplace should only have items needed for the current operations in their bare form.

Why is it important to sort?

With enough space, time and efforts can be managed effectively as everything is in its place. In addition, it removes any annoyances and hindrances in the workflow management and lowers incidences of injury where there are moving parts in the production process.

2. Set in Order

The setting order involves arranging items such that they are in the area that they would be used. Each item is labeled for the ease of identifying it at the workplace.

Why is it important?

Setting things in order eliminates several kinds of waste that include;

· Waste of human energy as workers look for items across the facility

· Downtime as production activities await the delivery of the said items

· Difficulty in inventory management as some of the items cannot be traced.

US manufacturing school also teach the importance of putting everything in order as it lowers the chances that a wrong raw material may be used in producing a particular item.

3. Shine

Keeping the workplaces clean enhances efficiency and work morale. Clean machines and tools also work efficiently and do not break down now and then. The workplace and tools used daily should be cleaned each end of the day so that everything is set for the next work day. This applies to hand tools and CNC machining equipment at the workplace.

Why is it important?

· Clean machines produce items with fewer defects

· Puddles of dirt and oil are more likely to cause slipping injuries

· If machines do not receive regular maintenance, they tend to break down more often

4. Standardize

The above-said procedures should be maintained each day. The management of the workplace should standardize the processes so that the conditions do not deteriorate at any point. Similarly, the quality of the products should be maintained by such technology as CNC automation. CNC manufacturing ensures mechanical engineering products are cut to precision every time and products are of the same quality all through.

5. Sustain

The improvements on the procedures should be efficient in the long term. Inspections and audits help determine the effectiveness of any improvement in the production environment. US manufacturing schools teach on quality control especially in mechanical engineering and other production industries. If any improvement does not improve the quality of the product, lower the cost of production or make the work easier, it is not worth implementing.

There is high competition among competing firms in US manufacturing industry. One way a company can lead the pack is by cutting down the waste and maintaining the product standards. In addition to the procedures taught in mechanical engineering schools production managers should enhance optimal productivity by making the workplace efficient, clean and inviting.
