When two or more refrigerant are mixed what must be done with the mixture

Refrigerants are chemical mixtures composed of several substances. During the HVAC cycle, refrigerants can usually exist in several states.
These substances have very dangerous and destructive effects on the environment.

Based on this, if two or mire refrigerants are mixed together, the mixture must be recovered into a separate tank and sent to the specialized facility to destroy it. 
The destruction of the mixture should only be done by experts in specialized facilities.

Hope this helps :)

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
