Museum of Science and Industry

We look after our collections so that they can be seen, enjoyed and studied today and in the future. We do this by controlling the agents of decay, such as heat, humidity, light and pollution. For example, our Strongroom for archive collections (see above) needs to have very stable temperature and humidity. This is because paper can become very brittle in dry air and may develop mould in warm, moist air. 

We monitor the environment that galleries and stores provide by using electronic sensors that log temperature and humidity readings continuously. The readings are transmitted wirelessly to a computer where they can be uploaded so that the data can be stored and analysed. We also take manual readings of light levels in galleries where light-sensitive material, such as textiles or documents, is displayed.   

One of the biggest risks to objects and archives is when anyone moves and handles them. Careful handling by both Museum staff and visitors is essential. We wear gloves to protect items from the acidic moisture on our hands.  Working objects, such as the steam engines and textile machines, are regularly inspected to check for signs of wear or damage.
