Stairways |
|
|
Return fire stairs, taken from fire door (on the left) and from landing. Note that the floor landings are directly above one another, hence the term "return" stair, meaning that it returns to the same place (one floor above or below.) |
|
|
Access stairs, from top and bottom. Note that there are no walls surrounding them to prevent smoke or flames from spreading from lower floor to upper. Question: if these two stairs were moved and placed next to each other, and were enclosed as fire stairs, what kind would they be called? |
|
|
Fire stairway door, taken from the stairway side. The sign at the top of the door reads "8"; on the door signage reads "re-entry on this floor. No re-entry on floors 9-13" and "smoking prohibited in stairways and corridors." There are at least three things wrong here. What are they? |
|
|
Two fire stairway doors, taken from the corridor side. Above the left door is "stairway 1B", on the right is "stairway 1C". One more time: what's wrong? |
|
|
Misc. |
|
|
Fire alarm control panel. |
|
|
A floor plan that wouldn't pass inspection. Why? Because it's a blueprint which has faded so much that it's unreadable. |
|
|
Fire fighters' emergency telephone. This one happens to be in a mechanical room. The second photo shows the same phone with the door open. Note there's no dial. |
|
| Elevator control panel, showing fire department key switch and instructions. | |
There are many other kinds of fire safety
equipment which I don't have photos. If you can supply any such
images, please email
them to me as attachments (sorry, no payments made; I'm not paid for these
either).
If I publish them here, I'll give you the credit.
