Trash Chute

Cleaning

• A trash chute is a vertical

duct in a building.

• It has side take-offs.

• It is open at the bottom.• The driving force is gravity.

• Because the world is not

perfect, nor is sealing, it is also an air duct that conveys

air.

• Natural air flow is upwards

from the bottom.

How do you clean a Trash Chute?

• The “contaminant” is hardened,

putrified garbage amongst other

things.• Left over paint is frequently found

• Unless you have a chute on a regular

cleaning schedule, you have no idea how long that has been hardening.
