Thankfully nobody was harmed.
The site has been assessed for reinforced autoclaved aerated concrete (RAAC), with none present.
Several tiles have been removed, and colleagues are assessing the ceiling, just to make sure there are no underlying issues, and in the meantime, props will be put in place as an additional safety measure.
Once again, this incident serves as a reminder of the challenges associated with operating within an aging site, with infrastructure which dates back to the 1930s and 1960s.
