Personnel hygiene station in slaughter and cutting plant

In 2018, an existing personnel hygiene sluice in the access area to the production area was expanded with a double-lane, force-guided automated soaping system for an owner-operated slaughterhouse and cutting plant for pigs in northern Germany.

Task

An already existing personnel hygiene sattion with hand disinfection and sole cleaning as well as 8 hand washing stations with manual soap dispensers was to be expanded with an access control system including time recording and automatic 2-hand soap dispensers with turnstiles, so that the personnel were forced to wash their hands before entering the hygiene area. The employees have to check in and also check out by RFID chip card.

A key driver for the implementation of the conversion was the elimination of overlapping breaks. The simultaneous departure of 120 employees from production and their simultaneous return led to bottlenecks and unnecessary waiting times due to the existing turnstile system. To counteract this problem, we opted for this solution in order to optimise the flow of staff and at the same time meet the strict hygiene requirements.

In addition, the task was not only to save paper for hand drying by using hygienic high-speed hand dryers, but also to minimize the personnel and time required for waste disposal, storage and purchasing of the paper. In addition, a positive side effect of the changeover was to be the avoidance of wet, unsightly scraps of paper inside the hygiene lock due to, for example, full waste baskets or employees not disposing of paper scraps accurately.

The office of the plant manager, which is located within the production area, should also be equipped with an automatic 2-hand disinfection machine with door contact switch. Only after disinfection of the hands does the plant room door receive an electrical opening impulse for access to the hygiene area.

Project description and special features

  • Two double-lane 2-hand soap dispensers with turnstiles of the Soap-Control Duo Highline type were positioned as access controls in conjunction with a time recording system before entering the personnel hygiene lock. All employees are now required to first log in via RFID chip card in order to then be able to apply soap to both hands simultaneously. The automatic soap dispenser is switched off using sensor control technology that is safe from unauthorized access. It is not possible to trick the user by attempting to apply soap to one hand or by deception. If soap has been applied to both hands, the electric turnstile enables access to the hygiene sluice for one person. The connections for power and data lines are installed from the ceiling.
  • An electronic time recording system for each lane is installed on the respective 2-hand soap dispenser for the outward and return journeys, which documents the working and break times by chip card before access or after leaving the production area. The forced sequence of the hygiene station only starts after the employee's chip card has been detected by the reader.
  • Stainless steel guide barriers (railings) with integrated locking bars (so-called pig ears) prevent "bypassing" of the soap application process by pulling back a locking arm of the 3-arm turnstile in the opposite direction and "slipping through" the personnel.
  • The 4-lane access and simultaneous return of the personnel ensures that no employee gets in the way of the hygiene process, that distances can be maintained and that personnel congestion is avoided.
  • For hand cleaning, employees have 8 hand washing stations, divided into 2 individual stainless steel hand washing troughs mounted back-to-back. Each washing station is touch-free (sensor-controlled).
  • Hand drying takes place by means of four Jet-II high-speed hand dryers installed on the wall side within 10 seconds.
  • In the further course of the hygiene sluice planned in the room, a continuous sole cleaning system with 2-hand automatic disinfection machines from a third-party manufacturer follows before access to the production rooms (hygiene area).
  • Here, automatic sole cleaning via brush rollers takes place permanently and independently of time recording. This ensures that the return journey from production to the social and changing rooms can be made via the same hygiene station.
  • The optimized railing also makes the individual steps of the hygiene station an inescapable feature.
    For the cleaning staff, too, an escape-route-capable railing gate system with a sticky-magazine locking system was installed, which is coupled to the fire alarm system via a Rittal compact control cabinet and releases the escape or rescue route n the event of panic.
  • In addition, a 2-hand disinfection machine type Desi-Star Highline was installed in the office of the plant management, which was coupled with the operating room revolving door via the potential-free contact. Only after correct 2-hand disinfection has been carried out does an electrical pulse release the door for access to the production rooms.
