Tools are appropriate and well-designed for safety. Set-up part positioning, controls and fastening systems should be reliable and durable. Holding systems, screens, or other barriers prevent the flying of parts, liquids, or piece fragments. Vacuuming, wiping, etc. is used for cleaning purposes (rather than using air to blow off). If possible, the machine start switch is linked to the closing and locking down of covers. Depending on the type of the product/chemical, safety showers and eye-wash fountains are installed nearby.
