Air showers are generally constructed from cleanroom-compatible steel or plastic materials and feature electronically-powered blowers, filters and high-pressure jet nozzles, the latter being incorporated into the walls and ceiling of the chamber. Air, at velocities of 3,000 to 7,000 feet-per-minute (FPM), continuously streams from the jet nozzles for 30-45 seconds, effectively removing loose particulate matter.
Personnel inside the enclosure will lift their arms and turn their bodies for uniform exposure to the air streams, a procedure usually specified in protocol. Air currents from the jets create shearing and flapping forces, which lift and remove contaminants from both flat surfaces and the creases of garments. HEPA filtration within the air shower is capable of removing 99.97% of particles greater than 0.3 µm diameter.

Air showers are specialized enclosed antechambers which are incorporated as entryways of cleanrooms and other controlled environments to reduce particle contamination. Air showers utilize high-pressure, HEPA- or ULPA-filtered air to remove dust, fibrous lint and other contaminants from personnel or object surfaces. The forceful "cleansing" of surfaces prior to entering clean environments reduces the number of airborne particulates introduced.
When properly incorporated into cleanroom design, air showers provide an ISO-classified transition vestibule to ensure the cleanliness of the classified cleanroom. Air showers are typically placed between a gowning area and cleanroom; after workers don appropriate garb and personal protective equipment, they enter the shower so that the pressurized air nozzles remove any residual particles from coveralls. Once the program cycle is complete, users exit through a second door into the cleanroom. Air showers (or air tunnels) may also be placed between cleanrooms of different ISO ratings.
What other factors should I consider when selecting and using this type of emergency equipment?
Potentially hazardous substances in the immediate work area
All hazardous substances need to be properly identified. A review of safety data sheets (SDSs) and labels can help to evaluate the hazard. To select the appropriate eyewash and shower equipment, you must know about the chemicals you use and their potential risks!
Number of workers in an area with a hazardous substance
More than one emergency shower or eyewash station may be required in an area where many workers use hazardous substances. Evaluate how many workers are using the hazardous chemicals, and provide more equipment where necessary to ensure the each worker's protection.
Isolated workers
The installation of an audible or visual alarm can alert other workers when the emergency shower or eyewash station is being used. An alarm is especially important if only one worker happens to be working in that area. A person may need help in getting to the eyewash if temporarily blinded. Some companies connect valves electrically to warning lights or buzzers in central areas.
Comfort and warmth
Extra overalls and foot covers should be stored near emergency showers. Clothes contaminated with corrosive or toxic chemicals need to be removed from the injured person. Consider installing a privacy curtain (but remember to maintain the 'obstacle free' diameter dimension as stated in the ANSI standard.)
Quality of the Flushing Fluid
Changing the fluid in self-contained systems frequently and cleaning the units regularly can prevent inadvertent use of contaminated fluid. Refer to the manufacturer's instructions for further details. Even in plumbed eyewash stations, the water may contain contaminants such as rust, scale and chemicals. Systems should be flushed and cleaned regularly.
Neutralized Solutions
It seems logical to neutralize exposure to an acid with a base or vice versa. However, there are concerns that attempts to neutralize chemical contamination of the skin or eyes could increase injury by causing:
▪a delay in starting irrigation while first-aid providers search for special irrigating fluids
▪ thermal burns from the heat given off when the two chemicals react, and
▪ additional injury due to contact with the neutralizing agent.
