Before construction begins in a healthcare facility, the project team must conduct a thorough risk assessment to evaluate potential impacts to life safety systems and develop interim life safety measures (ILSM). The risk assessment team should include facility staff, project managers, safety personnel, and clinical staff. All ILSM such as alternative egress routes, signage, staff training, and notifications to emergency responders and regulators must be carefully planned, documented, and communicated to maintain life safety during construction activities. Proper management of ILSM is critical to mitigating risks to patients, staff, and visitors.
