Answer to Question 1

The refrigerant detector will activate an audible and visible alarm and mechanical ventilation within the space.

Answer to Question 2

Refillable cylinders used to recover refrigerant must be inspected and hydrostatically tested a minimum of once every five years in accordance with Title 49 CFR Section 180.205. Some cylinders also have a last permissible use date. These are commonly known as 5 + 5 cylinders. They can only be re-qualified one time. These cylinders may not be used past the last permissible use date.
