Environment, Health & Safety committee made up to identify and resolve health and safety issues in the workplace.
The Role of the committee in:
Minimising failure rates
The aim of this option is to increase product quality by minimising failure rates.Your products are the figureheads of your company, having a significant impact on your company’s reputation. Minimising failure rates supports your efforts to deliver products of prime quality and should thus be seen as a key strategy for your business success. While most failures occur during the processing, their cause might be found in-house as well as beyond your company’s gates, at your suppliers’ or shipper’s side. Inferior raw material and chemical quality, inadequate handling or unprotected transportation of products are just a few examples.
For an overview of your most frequent failure rates, fill out the table below. Describe to the best of your knowledge the failure, the process and exact location (e.g., which (part of the) machine/process), as well as the cause (see further guidance below the table) and the number of failures. If available, use data from the last fiscal year or the last quarter and state the chosen time-period in the table. Otherwise collect the necessary information. Also try to fill out the total number of failures that occurred during the time-period, which should not simply add up to rows above, but summarise all the failures.
Total number of failures:
For comparability reasons, make sure to use the same time-period (e.g., one fiscal year) for all failures. In case you do not have the information and/or cannot collect it, try to fill out table based on estimates. In this case, mention in the comments line that the figures are based on estimates. Using the generated data will help you to draw a trend line of your performance over different time-periods (benchmark), to identify improvement options and to set targets. With a benchmarking process you can compare your performance internally as well as externally, with industry averages or competitors. To benchmark your performance and see your improvements, use a “failure per unit” ratio. The “unit” should be the unit of production that is most useful for you. Examples could be “kg or m2 of product” or “1 000 units of product”.
Following the identification of failures you should determine their causes, as this allows you to remedy the defects. Next to technical problems with your processing technology, the following causes can be commonly found:
• Poor quality input material delivered from suppliers
• Non-existent quality control of the water supply bases on critical parameters (softness, iron content, colour, buffer capacity, conductivity, etc.)
• Sub-optimised material for your machinery
• Lack of proper training for the employees to locate and fix malfunctions
• Lack of processes and products monitoring (accuracy of the recipe, water solubility, pH, colour, conductivity)
• Absence of written instructions on how to operate the technology
Having identified the causes you should aim to remedy the defects.
As a complementary strategy, you might want to inform the employees involved in processing about the necessity of minimising failure rates. Providing information about the failures and malfunctions that occur is the first step to address these problems. Update your staff about your efforts to reduce the number of failures and publicise the results of your efforts to ensure an ongoing support.
Failure minimisation results in a more efficient production with lower energy, water, raw- and auxiliary material consumption, adequate chemical use and a reduction in the amount of wasted textiles that need to be disposed of.
Following an initial assessment, this option will require investments in both time and money. However, significant savings in materials, energy and water, as well as an increase of product quality can be achieved. Applying measures to improve product quality, the share of second quality or waste products can be reduced by 5% to 35%. Increasing your product quality will also satisfy your customers and open up new business opportunities.
The functions of the Effluent Treatment Plant Design committee in :
- Fire safety conscious.
- Maintaining records and minutes of committee meeting every 3 month.
