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.

According to the CDC, approximately 31.7% of the U.S. population has high low-density lipoprotein (LDL) or "bad cholesterol" levels.

Did you know?

Less than one of every three adults with high LDL cholesterol has the condition under control. Only 48.1% with the condition are being treated for it.

Did you know?

The newest statin drug, rosuvastatin, has been called a superstatin because it appears to reduce LDL cholesterol to a greater degree than the other approved statin drugs.

Did you know?

Serum cholesterol testing in adults is recommended every 1 to 5 years. People with diabetes and a family history of high cholesterol should be tested even more frequently.

Did you know?

People with high total cholesterol have about two times the risk for heart disease as people with ideal levels.
