Technology News 509 - a new method to clean dust from soiled work clothes.
NIOSH 2005 May; :1-2
The new NIOSH-developed clothes-cleaning process has been shown to be much more effective in removing dust from a worker's clothes than the methods currently used by workers. This process uses a compressed air nozzle manifold to blow dust from the worker's clothes in an enclosed booth. Since the air exhausted by the dust collector causes the booth to be under negative pressure, no dust escapes to contaminate the work environment or other workers. Test results showed that the NIOSH process cleaned the work clothes 10 times faster and removed up to 50% more dust than the single air hose or vacuuming methods. The average cleaning time with the NIOSH technique was less than 20 seconds. The cost of this clothes-cleaning system was approximately $3,000, excluding the cost of the exhaust ventilation component.
