Control measure

Monitor for signs of collapse or instability of temporary structures

Control measure knowledge

Temporary structures may collapse suddenly, with little or no warning. It is important to understand the type of construction involved and the method and sequence of construction or erection. This information should assist in assessing the likelihood of partial or structural collapse.

Partial collapse of a temporary structure may lead to instability and further collapse, especially if it is subjected to strong winds or other loads.

For further information about signs of collapse due to fire, see National Operational Guidance: Fires in buildings - Assess and monitor structural integrity: Unstable structure

Strategic actions

Fire and rescue services should:
  • Gather information about the location and type of temporary structures where feasible

Tactical actions

Incident commanders should:
  • Liaise with the responsible person; in the case of temporary structures this may be a hire company
  • Identify the type of structure, its method of construction and what it is being used for
  • Look for signs and assess the likelihood of instability or collapse
  • Look for signs of structural support that has been compromised or is missing
  • Look for and assess the suitability of temporary supports, ground anchors and propping
  • Consider the impact of current and forecast weather conditions on temporary structures
