Cleanrooms are highly controlled environments with rigorous cleanliness standards. Some of these cleanrooms deal with chemicals or substances that are hazardous, flammable or toxic. With these hazardous substances comes risk, and extra safety precautions are required. Depending on the various types of hazardous substances in the room, specialized clothing may be required. This may include goggles, various types of gloves, head or face coverings, and perhaps even a full bunny suit. This clothing serves two purposes, as it can protect the cleanroom user from the hazardous substances and can keep particulates shed by the user from entering the room or contaminating cleanroom processes. If a toxic material is released in a cleanroom, a fast detection is of paramount importance. Many cleanrooms that work with these types of substances are equipped with chemical or gas detectors. These detectors are often quite advanced pieces of equipment and can tell where substances may be leaking in a room. Additionally, HVAC units may be monitored for these chemicals or substances. A leak or spill of these hazardous or toxic components could have drastic results. In addition to the protective clothing and detectors, there should also be a written plan for cleanroom workers to follow. These written plans provide clear instructions for a whole range of activities conducted in the cleanroom, but most importantly, detailed plans on how to handle different kinds of emergencies. In conclusion, cleanrooms are very delicate environments, and some cleanrooms can work with dangerous substances. Having the proper means to detect these substances, as well as a written plan, will help ensure safety for the cleanroom workers, as well as the integrity of the cleanroom.
