Lighthouse Thailand held a seminar called "Cleanroom Classification and Monitoring for Hospitals" at the Rajavithi Hospital in Bangkok, Thailand on Aug 19-20, 2016. Seventeen different government supporting organizations sent 45 Medical Device Engineers and Heads of Operating Rooms to attend the seminar. These 17 groups support all 76 provinces of Thailand. The seminar topics included real-time contamination monitoring, ISO 14644-1, workshop and testing of hospital OR rooms.The seminar was very well received by all the attendees and we are looking forward to hosting more of these seminars in the future! Thank you to Marcel van Haaren, Kris Teo, the Lighthouse Malaysia and Thailand teams.
