Compressed gas cylinder components contain a number of visual clues to indicate their proper use. Look carefully at a cylinder in your laboratory, focusing on the regulator connection hex nut (pictured in the circle) for example, and you will see a stamped CGA number. This number must match the stamped CGA number on the valve (pictured in the triangles); if not, cross threading and leakage can occur. Likewise, a noticeable notch on the regulator connecting hex nut (pictured in the square), indicates the threads are of reversed thread design, meaning one would need to turn them clockwise to remove the nut. When connecting these components a small 10" sized adjustable wrench is all that is needed to make the final connection; never use teflon tape (pictured in the x) on the male or female type threads to achieve a tighter seal. Finally, always check the connection with an approved liquid indicator solution for any leaks; if leaks cannot be controlled, notify your supplier of the situation and follow their instructions.
In our pursuit of continuous quality improvement, EH&S is transitioning Regulated Medical Waste (RMW) services to a new vendor, Approved Storage & Waste Hauling (Approved), at the Morningside Campus, beginning in 2013. All service-related logistics of the RMW program will remain the same (i.e., Tuesday and Friday pick-ups), however new containers with improved features will replace the current stock of containers. Approved will also utilize a pickup attempt service notice, pictured here, for the same purpose as under the current program. A laboratory will receive the service notice if their RMW waste container(s) - either red bin or sharps - are not suitable for pickup and disposal. The container(s) cannot be picked up until identified issues are corrected. Examples of issues that will result in a service notice include:
