'Dry riser' nghĩa là ống đứng không có nước, thường liên thông với nhiều tầng của một tòa nhà để ráp vòi chữa cháy vào khi có hỏa hoạn (A dry riser is a normally empty pipe that can be externally connected to a pressurized water source by firefighters. It is a vertical pipe intended to distribute water to multiple levels of a building or structure as a component of the fire suppression systems).

Ví dụ
Fire crews put the fire out using a hose reel via the tower blocks internal dry riser system.

We also charged the dry riser system in case the fire spread, but it didn't and was extinguished quite quickly.

Although the photo shows that the dry riser opening is not obstructed, but CWS ascertains that there had been a door that prevented the cat from coming out.

'A dry run' nghĩa là cuộc diễn tập, cuộc tập trận (an occasion when you practise doing something to make sure there will be no problems when you really do it; a rehearsal of a performance or procedure before the real one).

Ví dụ

Bride Lucie Jones uses Eurovision as dry run for wedding.

In a statement this week, it added that the HSE has undertaken one “dry run” of the new facility, which took place on May 17.

While nurses say one dry run simply isn’t enough, the hospital’s statement also insists they have not been told this by nursing unions before now, and they describe it as “regrettable” that the INMO spoke publicly before writing to management.
