This is part of our new Blog Series…Signal Application Tips by Industry. We hope you find these helpful in determining how and where to use Tomar Signaling Products.
Pharmaceutical operations are characterized by large, clean process areas with much movement of materials. In the office areas adjacent to production facilities the MicroLERT may be used as a visual signal to indicate a no-entry point. These areas usually do not warrant a heavy-duty alarm, and the MicroLED is more aesthetic than a typical industrial signal light.
Pharmaceutical plants are typically well automated, and therefore offer an expanded opportunity for process control signaling. These include the 440 Microstack, the LED Microstack, MicroLERT, and Microstrobe. An external sensor or PLC usually triggers each audible/visual device. Typical applications would be start-up/stop of conveyors, alert of problems on the production line, high/low levels of raw materials, and movement of large pieces of machinery or equipment.
Process areas of pharmaceuticals can be hazardous environments with the presence of numerous chemical and corrosives. The Model 490S-T and 4375 are especially well suited for pharmaceutical applications where manufacturing equipment is usually hosed down.
Complete plant-wide evacuation systems the 1000/1100 Power Alarm or even 10002WEP for indoor and outdoor warning alarms are sometimes in place in these plants given the large amount and mix of chemicals present. Research and Development areas are also affected. Sometimes radiation is present in these plants and requires alarm equipment.
Pharmaceutical facilities may have their own power plants and the inherent hazards there (see Power Plant Application Tips for more details on the use of signals). These plants also have water treatment facilities that require appropriate alarm equipment. The potential danger here is chlorine, which constitutes a Division 1 or 2 hazardous area. Think 3000 or 7000 series explosion-proof strobes and LED’s.
The widespread use of chemicals in pharmaceutical plants requires the storage, movement, and use of sometimes dangerous chemicals or derivatives. Visual and audible alarms are used to communicate conditions such as “Do Not Enter”, “Contamination Warning” or “Testing” in plants. These facilities are usually highly corrosive due to the presence of airborne chemicals. Heavy-duty general industrial or hazardous-area alarms are often required.
