The Philippines' Fire Season and Heat Season Are the Same Season, and BFP Crews Are Working Both at Once

In the Philippines, fire season and heat season are not two separate problems. They are the same three months. The Bureau of Fire Protection (BFP) recorded over 15,679 fire incidents in 2023, a 20.7 percent jump from the year before, concentrated almost entirely in the March-to-May dry season, the exact window when PAGASA's heat index routinely crosses into "Danger" territory. Firefighters responding to those calls are doing so in full turnout gear, on days when the ambient heat index alone is already flagged as a health risk before anyone lights a hose.

Two curves that peak together

BFP data shows fire incidents rising sharply every summer: an average of nine fires a day in March alone, enough that the government designated the month Fire Prevention Month by presidential proclamation. Electrical overloads, unattended open flames and LPG-related accidents drive most of these calls, worsened by aging infrastructure and rising electricity demand as households run cooling equipment harder during the heat.

The same window is when PAGASA's heat index readings climb into their most dangerous range. On multiple days this year, Metro Manila and dozens of provincial areas recorded heat index values between 42°C and 46°C, PAGASA's "Danger" category, where the agency's own advisory states that heat cramps and heat exhaustion are likely and heat stroke is probable with continued exposure. Areas including Dagupan City, Aparri, Casiguran, San Jose in Occidental Mindoro, Cuyo in Palawan and Dumangas in Iloilo have each logged danger-level readings this season, some for several consecutive days.

What that overlap means for a firefighter in turnout gear

A heat index in the Danger category already carries elevated health risk for someone standing still in the shade. For a BFP firefighter working a structure fire in full PPE, the risk compounds. Turnout gear blocks the evaporative cooling that would normally offset high ambient heat and humidity. Radiant heat from the fire itself stacks on top of an ambient heat index already at 42°C or higher. Extended structural response, common in the densely built, closely packed neighborhoods where the BFP notes many fires originate and spread quickly, keeps crews in gear for longer than a controlled burn would require. With 34,474 personnel covering 51 city stations and 597 municipal stations nationwide, and frequently relying on volunteer force multipliers to cover call volume, rehab and cooling capacity at the individual station level varies widely.

This is the same exertional heat stroke risk profile documented for structural and wildland firefighters everywhere, but in the Philippines it is guaranteed to occur during the same weeks every year, because the fire season and the heat season are, structurally, the same season.

Cool First, Transport Second does not require a wildfire to apply

The ACSM Expert Consensus Statement 2023 and IOC guidance (Hosokawa Y, Racinais S et al., BJSM 2021) apply to any exertional heat stroke case, structural firefighting included: cold water immersion should begin on scene, before transport, to bring core temperature below 39°C within 30 minutes of collapse. Casa et al. (Exercise and Sport Sciences Reviews, 2007) measured a cooling rate of 0.35°C per minute with this method, roughly ten times faster than wet towels or ice packs, and the Korey Stringer Institute's dataset of over 401 cases treated this way reports a 100 percent survival rate when temperature drops below 40°C within that window. The protocol was built around exertional heat stroke as a physiological event, not a wildfire-specific one, which makes it directly applicable to a BFP crew coming off a structure fire on a 44°C heat index day.

Cooling equipment sized for a station budget, not just a wildfire season

Kollder One's case for BFP stations is different from its case for wildland fire services: it is not about multi-day deployments on remote terrain, it is about having on-scene cold water immersion capability ready at any of the country's 648 fire stations, deployable by a single responder in under 2 minutes, without needing a fixed medical facility nearby. Fire services and EHS teams assessing heat readiness ahead of next year's March-to-May peak can request a Kollder quote.
