While clean rooms maintain a carefully monitored environment free of contaminating particles and humidity, there are nevertheless some things to consider when it comes to dealing with a cleanroom work environment.

Staff should wear full protective coverings such as hoods, specially designed jumpsuits, shoe covers or special boots, and whatever else is necessary to conduct sensitive tasks. Safety goggles or glasses should be used when working with chemicals. Face masks and shields should be used for sensitive processes that could lead to breaking glass or explosions. Always use gloves to handle dangerous chemicals and to prevent shedding skin contamination. Some processes require a respirator, so be sure to have the necessary training and qualification to use those if need be.

Processes in cleanrooms can often involve chemical handling such as possibly hazardous acids, bases, solvents, carcinogens, and cryogenics. Understand the present materials and their use and know the proper procedures of handling and disposing waste. If you come into contact with such a chemical, rinse the area with water for 15 minutes and remove any affected clothing. Hydrofluoric acid can be especially dangerous if eye or skin contact occurs. Such a substance can burn through tissue and even bone which can be very destructive. As stated above, rinse any affected area with water and get medical help.

Chemical processes should be conducted under fume hoods or in wet benches if they pose the risk of spilling. Chemicals should be carefully labeled and stored. All chemicals and mixtures should be properly cleaned and hazardous waste disposed of.

It is useful to know the layout of the cleanroom and to know where the necessary safety equipment is such as safety showers, fire extinguishers, eye wash stations, and emergency shut off switches. It is good to know what emergency signals and alarms indicate, and where to evacuate if necessary. Maintain familiarity with hazardous gas monitoring equipment and any alarms that might indicate hazardous air conditions.

These tips don’t cover everything. Make sure you understand all of the necessary safety precautions and instructions, and make sure the rest of the workers that use a cleanroom and work with processes inside do too. Following some of these basic points will help to eliminate many potential dangers however.
