A warehouse fire at Doric Products in Marshall, Illinois pushed firefighters to their physical limits on September 4, as they battled flames inside heavy protective gear while the heat index climbed close to 105 degrees. The Marshall Fire District brought in extra personnel and support from Clark County emergency management just to keep crews safe enough to keep working.
Marshall Fire District Chief Jerry Parsley said temperatures at the scene reached 95 degrees that day, according to WTHI-TV, even as the heat index felt closer to 105. Parsley said firefighters face serious safety risks when layering on protective gear in rising temperatures, and that wearing full gear in extreme heat is stifling and energy-depleting. He said his job includes making sure his firefighters are taken care of, looked after, and safe, adding that he must balance his team's safety with the demands of the job on extremely hot days.
The fire itself started when employees noticed smoke coming from an interior wall near a plugged-in lithium battery charger, according to the Daily Dispatch. Flames spread rapidly behind the wall and engulfed the 100-foot-long structure. Employees evacuated safely, and no injuries were reported among staff or emergency responders. The warehouse destroyed in the blaze was used by Doric Products, Inc. to manufacture display vault models and a baby casket line, though core burial vault liner production in adjacent buildings on the property remained unaffected, per Connecting Directors. The company, founded in 1955, operates multiple manufacturing buildings at its Marshall site.
Extra Crews and Cooling Stations Kept Firefighters Going
To keep the operation staffed through the heat, the Marshall Fire District worked with the Martinsville Fire Department to bring in extra personnel during the fire, the station's report notes. That additional manpower allowed each firefighter to take necessary breaks rather than pushing through exhaustion. Some firefighters went to a waiting ambulance for rehabilitation during the incident, and Clark County EMA was on-site specifically to look after crews working the scene, providing water, Gatorade, and ice-cold wet towels.
Marshall sits in Clark County near the Indiana border, roughly 20 minutes east of Terre Haute, according to Sentinel Emergency Solutions. During the fire, Marshall worked with the Martinsville Fire Department to bring in extra personnel. Illinois departments coordinate that kind of support through the Mutual Aid Box Alarm System, a statewide network that deploys extra manpower and equipment when local agencies face severe heat or major fires, according to MABAS Illinois. Pre-planned box cards dictate which surrounding departments respond as alarms escalate, which is effectively how Marshall pulled in help from Martinsville.
Why Turnout Gear Becomes a Liability in the Heat
The same gear that protects firefighters from flames also works against their bodies once the temperature climbs. Standard structural firefighting protective gear — bunker coat, pants, boots, gloves, helmet, and self-contained breathing apparatus — weighs about 45 to 55 pounds on average, and can exceed 70 to 80 pounds once tools and water-soaked hose lines are added, per Patch. NFPA-certified turnout gear uses multi-layered moisture and thermal barriers that can trap internal body heat and sweat, according to Firehouse Magazine, restricting the evaporative cooling that is the body's primary defense against overheating during strenuous work.
That physiological conflict has serious consequences nationally. A National Fire Protection Association report on 2025 data found heart attacks remained the leading cause of death among U.S. firefighters, accounting for 45 of 83 total line-of-duty and 24-hour post-duty fatalities, according to Occupational Health & Safety. Volunteer firefighters accounted for 16 of the 18 heart attack deaths that occurred within 24 hours after completing duty in 2025, the outlet reported. Research cited by the National Volunteer Fire Council indicates sudden cardiac events cause 40% to 50% of all annual line-of-duty firefighter fatalities, with 36% of those fatal cardiac events tied to high-exertion fire suppression work in high-heat environments.
Rehab Protocols Aim to Prevent Collapse on the Fireground
Heat stress isn't the only internal risk. Centers for Disease Control and Prevention occupational health research highlights that firefighters performing heavy labor inside thermal gear during high ambient temperatures face acute kidney strain, severe dehydration, and elevated risk of rhabdomyolysis, as Hoodline has previously reported. Heavy sweating without adequate hydration and electrolyte replacement can lead to rapid muscle breakdown and added kidney stress.
To manage those dangers, the national standard NFPA 1584 mandates formal firefighter rehabilitation protocols during emergency incidents — vital sign checks, active cooling, fluid replacement, and mandatory rest periods after a firefighter exhausts two 30-minute SCBA air tanks or operates under severe heat conditions, according to JEMS. That standard was created specifically to reduce on-scene heat exhaustion, collapse, and cardiac incidents, and it lines up closely with what played out in Marshall: extra crews rotating in, an ambulance serving as a rehab station, and Clark County EMA on hand with water and cooling towels for firefighters working through the heat at the Doric Products fire.
