Collections to look after and halls that change every week: how the ducts of a museum or a convention center are reviewed

In a museum the collection rules and in a convention center the calendar rules, and in both things are coordinated before a duct is opened.

Short answer

Duct cleaning in museums and convention centers is the camera inspection and cleaning of the ducts that air condition exhibition rooms, halls and support areas, coordinated with the conservation team and the event calendar. The camera goes in through the duct access doors and whatever is not opened is noted.

What sets museums and convention centers apart

The collection decides when and howThe conservation team says which rooms can be worked on, at what hours and with what care. This page does not define them, it follows them.

Halls that change with each eventIn a convention center occupancy goes from empty to full from one day to the next, and the setup calendar marks the gaps.

Humidity that is checked, not assumedIn a humid climate it makes sense to know whether water or mold is visible on ducts and grilles. The inspection allows checking it room by room.

Facts that help decide in museums and convention centers

In Panama: The country’s Historical Heritage museums received 120,120 visitors between 2022 and 2024, and Panamá province accounted for 46.8%. The figure covers the museums that reported to the Ministry of Culture. (INEC, Culture Statistics 2022-24)
Technical fact: The Canadian Conservation Institute explains that at 60% relative humidity visible mold may already appear on some surfaces, although a stable humidity at that value is rare, and that at about 25 °C mold takes about 100 days at 70%, 10 days at 80% and 2 days at 90% or more. (Canadian Conservation Institute, Incorrect Relative Humidity)
Peer-reviewed study: A two-year study in two museums and a library in Greece measured particles and microorganisms and found PM10 and microbial concentrations higher indoors than outdoors, which it attributed to the presence of people and indoor activities. (Lazaridis et al., 2015, Heritage Science)

Types of place within museums and convention centers

Type of place	What changes in the work plan
Museums	Before opening a duct near a room, the conservation team is asked for guidance
Convention centers	The event calendar is the starting point and the days between setups are used
Event halls	Halls that are transformed with each setup: reviewed when they are cleared
Conference rooms	Unit and returns of closed rooms, before or after the day’s sessions
Libraries	Shelves and archives: visible moisture is checked and it is coordinated with whoever looks after the collection
Art galleries	Spaces with works on the walls: the gallery agrees which room and which day

How the work is organized in museums and convention centers

Agree with whoever looks after or schedules. With the conservation team or the events area it is defined which rooms are included, on what dates and with what care.
Inspect by room and by date. The camera goes through the agreed ducts in the gaps of the calendar, starting with the busiest rooms.
Hand over what was seen and what was not. The report separates what was observed from the rooms left out because of the collection or an event.

An example of what the report brings

An illustrative page from a museum report: room 4, upper floor. A photo of the duct access door, a photo of the return grille with a little dust and a decision line: monitor until the next review. It is noted that the neighboring room was left out at the conservation team’s request.

What you are left with at the end

A plan by room and date, adjusted to the venue’s calendar
Photographs of the inside of the ducts, with no images of pieces or artworks
The rooms left out because of the collection or an event
A suggestion of when to look again, based on the event season

Frequently asked questions

Are pieces or display cases touched?

No. The service is limited to the ducts, which are opened through their access doors, and the work zone is agreed beforehand with whoever looks after the collection.

Can the work be done with the museum open?

It depends on the place. The closing day or the hours without visitors are often preferred, and the museum team decides.

What if there is an event the next day?

The center’s calendar rules. The work happens in the gaps between setups and what does not fit is left for another date.

Are the humidity or temperature of the rooms measured?

It is not part of the camera inspection. If the conservation team has its own records, it can share them for the report.

How often does it make sense to check the ducts in museums and convention centers?

There is no fixed frequency. It makes sense to look before an event season, after large setups, or when the conservation team notices moisture or odors near a room.

What does the report include for museums and convention centers?

It brings photographs of the inside of the ducts. It is organized by room, separates what was observed from what was left out because of the collection or an event, and includes no images of pieces.
