 +=====Notes on Filling Dewar with LN2=====
 +  * Make sure you always use the static discharge strap whenever you're touching the dewar.
 +  * Before inserting the metal fill tube into the M4K touch it to the outside of the fill port
 +  * If the pressure in the LN2 dewar is low, you can hook up the dry nitrogen to pressurize the dewar and fill faster.  These dewars only allow 7 psi of pressure before venting, so please do not turn up the dry N2 higher than 7.  The M4K won't fill faster at this point, and dry N2 is being wasted. 
 +  * If you use the last of the LN2 in a tank please swap transfer tube to a fresh dewar.  Your certifier should have gone over how to do this.  If you don't feel comfortable doing this, reach out to Mountain Ops for training.  
 +  * **[[public:observer:stress_proper_ppe_use|Wear proper PPE.]]**  When handling LN2 in any capacity wear long pants and closed toed shoes.  You must also wear goggles AND a face shield when using liquid nitrogen, and cryo gloves.  You must also wear long sleeves when handling liquid nitrogen.  If you don't have long sleeves we've provided lab coats for you to use.
 +  * For the M4K, the dewar MUST be filled every 24hrs. NO EXCEPTIONS.
 +    * If a camera has gone longer than 24 hours, call a staff member. Sometimes the M4K is warming up deliberately, so always call if you find it over 24 hours between fills.
 +    * The staff member will probably ask you first if the scope is in lightning shutdown, if not they'll want you to check the cam temp on Azcam. NEVER FILL THE DEWAR ABOVE -40C
 +    * If the telescope is in lightning shutdown, they will ask you to check if the fill port is outgassing. Sometimes it is not readily apparent, so you will need to put your thumb over the fill port for 10 seconds and remove it to see if a spurt of gas comes out. They will also ask if the outside of the dewar is sweating. It will look like condensation on the outside of iced water. From this point on, the staff member will guide you as to what to do next.
 +    * Warning!!! LN2 can spill out of camera dewar after filling!
