When is it safe to operate a fog nozzle at 185 gpm?

Operating a fog nozzle at 185 gallons per minute (gpm) requires careful consideration of safety protocols, particularly regarding personal protective equipment (PPE). Utilizing appropriate PPE is crucial because it safeguards firefighters from potential hazards associated with high-pressure water streams, such as thermal injuries from steam, injuries from debris displaced by the water, and exposure to hazardous materials that may come in contact with the water.

The specific flow rate of 185 gpm, when deploying a fog nozzle, can generate a considerable amount of force and produce steam, especially in hot environments. Therefore, wearing PPE, including helmets, goggles, gloves, and protective clothing, is essential to mitigate the risks involved in effectively managing and directing the water stream while ensuring personal safety.

While other factors, such as pressure drops, supervision, and flow tests, are important in different contexts of firefighting operations, they do not address the immediate protective measures that personnel need when actively engaging with the nozzle at that flow rate. In this scenario, ensuring that all firefighters are equipped with the right protective gear prioritizes their safety over other procedural aspects.
