Combustible formwork fires are specifically noted for occurring during what type of construction activities?

Combustible formwork fires are specifically associated with the process of formwork installation in construction activities. During this phase, temporary structures made from wood or other combustible materials are created to support the pouring of concrete until it sets. Since these materials are often highly flammable and used in significant quantities, they present a substantial fire hazard if not managed correctly.

The presence of other construction activities, such as roofing, bricklaying, and electrical installations, does not inherently involve the use of combustible materials to the same extent or in a manner that contributes to fire risk as much as formwork installation. In the case of formwork, the environment and conditions can lead to fire ignition if sparks from nearby work or improper handling of materials occur. Effective fire prevention strategies are crucial during formwork installation due to these inherent risks.
