Dow has also been using DuPont coveralls for many years in areas where staff are exposed to hazards arising from solids and dusts; for instance, in the production of cellulose ethers which are used as fillers and binders in construction materials, cosmetics and pharmaceuticals. The suits involved here are primarily from the Tyvek® product line, such as Tyvek® 600 Plus. TRY BEFORE YOU BUY Before purchasing new or updated garments, Dow carries out comprehensive wear tests lasting several weeks or even months with its front-line staff. These tests are a useful factor in coming to a decision about which product is most suitable for staff and their specific working conditions and whether the chosen garment can prove its worth under practical conditions. Thiede explains, “DuPont assists us with these tests by supplying sample garments in various sizes. Our staff enter their ratings on questionnaires covering criteria such as wearer comfort, fit, freedom of movement, handling, size range and, of course, the wearer’s subjective feeling of safety.” Dow then jointly evaluates these questionnaire responses with DuPont. Positive and negative feedback about the garments may then be fed into further product development. Dow’s standard practice originally was to keep stocks of the garments in sizes M to XXL. Over the course of time, the wear tests have increasingly revealed demand for very small and very large sizes as well. One advantage of working with DuPont is their ability to respond to these changes in demand, because they can offer a wide range of different sizes which are available from stock or made to order. CONTINUOUS SAFETY IMPROVEMENT Dow and DuPont have now been working together for over ten years on the selection and use of suitable protective garment solutions for specific hazards and applications. The aim is to ensure ongoing, continuous improvement in staff safety on the Stade site. This is why the companies carry out joint workshops to inform heads of department, H&S coordinators, staff from partner companies and apprentices about protective clothing in general, the characteristics of Tychem® and Tyvek® chemical protective clothing, the correct way to donning and doffing and proper disposal after possible contamination. As Thiede says, “Participants in these training workshops pass on their knowledge to their departments and among their shift colleagues. Our aim is to make sure this knowledge is put into practice and widely disseminated so our staff can work safely.” DuPont has helped to support the dissemination of safety information by providing training videos and step-by-step instructions which Dow staff can access via an intranet platform. In addition, custom garment solutions were required for some areas of use: such as protective suits with reinforcement at specific points subjected to particular mechanical stress, or specific details such as attached heat-sealed gloves or boot cuffs. “In such cases, DuPont put us in contact with a company which has been able to finish the garments in line with our requirements”, explains Thiede. “Also, we regularly collaborate on optimizing and further developing the products with the aim of continually improving staff protection.” ROLL-OUT TO OTHER SITES Since Stade manufactures basic chemicals, the safety insights gained there can also be transferred to other Dow sites in Germany and Europe to deliver a number of benefits. Firstly, broader implementation generates cost savings, since there is no longer any need to select and assess various chemical protection garments and carry out wear tests at each site. Secondly, the resultant synergies can ensure greater harmonization of PPE between sites and so enable uniformly high occupational safety standards across Germany. “This obviously also makes things simpler and more efficient for both parties. DuPont has a single point of contact on the customer side and we are able to take delivery of larger quantities, making it a win-win situation for everyone”, concludes Thiede.
