Question:

How do I know if my glasses have antireflective coating?

Just asking because I'm going to the beach today and I'm legally blind. So dose the water affect the anti reflective coating? And how do I know if i have it?Thanks:)

Answer:

It's not designed to, but smoke of all kinds contains CO, so it is possible.
No way can you use PVC fittings on a gas line, they are 2 different compounds, and very illegal in the UK.
In most smoke detectors a steady green light means its working properly, a blinking green light means it is either on battery backup or theres a trouble such as a dirty screen. Red means it is in alarm for either no power, low battery or you have a actual fire.
