Warts: Liquid Nitrogen Treatment

Liquid nitrogen freezes and destroys both the wart and a small area of normal skin around the wart. A special spray bottle or a cotton swab is used to put on the liquid nitrogen. It takes about 10 to 20 seconds to apply. The liquid nitrogen is so cold it actually stings like frostbite or feels like an ice cube stuck to your skin.

Choose the right fluid for your pressure test

There are three choices for the test fluid: air (or nitrogen), process fluid (gas or liquid), or water. Each choice poses its own problems. Testing with compressed air is limited to about 80 psig, although nitrogen is often available from a utility provider at pressures of about 150 psig. A danger with compressed air is that it may be
