About Eugene’s Corner

For over five decades, Eugene Ngai has been dedicated to educating code officials, emergency responders, higher education institutions and industry professionals on the hazards of compressed and specialty gases. Through extensive research, publications, training, and working to establish safe practices and regulations, Eugene has become a global expert and…a legend…in compressed gas safety. He’s passionate about sharing his deep institutional knowledge and we’re delighted to make his exclusive collection (a treasure trove!) of resources available here, in Eugene’s Corner. Take a moment and read his Open Letter to Community and his biography to learn more about Eugene, his company Chemically Speaking LLC, and then browse and search this amazing collection of resources.
