Smoke shafts typically extend the height of multiple floors in a building and the size of the vent openings introduces a safety issue. It’s important to ensure that grills and fall arresters are installed as required to prevent accidental falls.
For single vents the vent will need to have an opening angle of at least 140°. Twin vents that are installed side by side should have each leaf open to at least 90°. This is primarily to reduce damage caused by wind and to ensure adequate airflow.
