White point fire commander5/15/2023 Even with a 360-degree walk around, the situation will be constantly changing and ongoing information on conditions from division and group supervisors will be needed to keep the action plan current and safe.Ībandoned and dilapidated buildings are a special consideration for a 360-degree size-up and decision-making. The incident commander must also understand the size-up is an ongoing process, requiring frequent progress reports from all points of the fireground. Until the complete 360-degree assessment is completed, the incident commander must be cautious in committing fire crews, must constantly monitor changing conditions and must be prepared to immediately adjust crew commitments or withdraw crews all together. Without it, the incident commander will be limited in vital information. You can’t under estimate the value of the visual observation of all four sides of an incident to the incident commander and effective command decisions. Later-arriving chief officers should be assigned appropriate division or group assignments to improve the 360-degree size-up for the incident commander and provide ongoing progress reports. ![]() ![]() Once the rapid size-up is completed, it’s absolutely essential that the incident commander establish a stationary command post, preferably in a fire-department vehicle. Where the chief has an aide, utilizing this member for size-up duties can be very effective. Typically, only a few fire companies are on the scene doing this short period and the incident-commander function won’t be compromised. In some cases, the first arriving chief officer assuming command can drive around the incident building or conduct his own walk-around, in order to obtain a complete 360-degree size-up of the fireground while assuming mobile command and directing companies for a short period of time. Where barriers prevent this, multiple companies will be arriving on scene in a relatively rapid sequence, and it may be more effective to quickly assign fire crews or other officers to various locations on all four sides of the building, obtaining a size-up report via radio from company officers. In the urban or suburban environment, four-member crews will allow two members to stretch an attack line while the company officer completes a 360-degree size-up. Additionally, where the initial arriving crew is three members, the OSHA two-in/two-out rule prohibits entry until another crew or officer arrives. Until other companies arrive, there are no other companies to command. In a rural environment, it may be many minutes before a second-due company arrives on scene, providing a reasonable period for the company officer or incident commander to conduct a 360-degree size-up. There are several approaches to obtaining the size-up. Evaluating these factors will allow the incident commander to forecast future conditions and risk and to develop a safe action plan. The incident commander must know what’s burning, where it is and where it’s likely to go. There will be factors that are visually present and those that aren’t observable from the command post. NIOSH firefighter fatality reports repeatedly cite a lack of a complete size-up as a contributing factor in firefighter deaths.Įach side of the fireground has its own unique fire conditions and risk that must be assessed. There has been much discussion in recent years about the need for the incident commander to conduct or obtain a 360-degree size-up of an incident. Objective: To cause the incident commander to obtain an early 360-degree survey and risk assessment of the fireground in order to determine the safest approach to tactical operations as part of the risk assessment and action plan development and before firefighters are placed at substantial risk. The first rule states: Rapidly Conduct or Obtain a 360-Degree Situational Size-Up of the Incident In this case, the incident commander is responsible for the safety of all firefighters operating on the fireground. This provides consistency in safety objectives but they're applied differently based on responsibilities. ![]() ![]() You'll recognize that several rules from the firefighter series cross over to the incident commander rules. This article begins the incident commanders' rules. Previous articles summarized the rules of engagement for firefighters.
