Fire Safety in Construction: Key Reminders for the Jobsite

July 2, 2025

At Morcon, we talk a lot about “Building with Integrity.” That doesn’t just mean delivering quality projects on time—it means protecting the people doing the work, every step of the way. And when it comes to fire safety, integrity looks like smart choices, safe habits, and knowing your A, B, C’s (yes, we’re talking fire extinguishers).

With the Fourth of July around the corner—and fireworks on everyone’s mind—it’s the perfect time to talk about fire risks that don’t just happen once a year. From hot tools to fuel tanks, jobsites carry real fire hazards every day. So let’s light up the grill, not the job trailer, and keep these key reminders in mind:

Know Your Fire Types (and Extinguishers)

Not all fires are created equal, and neither are extinguishers. Here’s a quick cheat sheet:

Class A = ASH (paper, wood, cloth)
Class B = BOIL (liquids—gas, oil, paint)
Class C = CURRENT (electrical)
Class D = DUSTS (metal shavings, magnesium)

Pro tip: Bigger number = bigger capacity. A 2A is better than a 1A. Keep them inspected and in the right spots.

Equipment Must-Haves

Fire extinguishers every 3,000 sq. ft. or 100 ft. max spacing
On every floor, and next to stairwells
10B extinguishers within 50 ft. of flammable materials
For larger flammable storage? You’ll need 20BCs nearby.

Don’t forget the water drums, hose lines, and pails if you’re subbing out extinguishers—just follow the code, and remember: freezing temps and water hoses don’t mix.

Cut the Risk at the Source

Store flammable liquids properly—safety cans, cabinets, or designated storage rooms
Keep temporary heaters away from combustibles (10 ft. minimum!)
Never block exits, fire doors, or extinguishers
Use flash arrestors on gas lines, especially acetylene
And yes—No Smoking signs are there for a reason (that includes around fuel cans)

Sound the Alarm (Loudly)

If a fire does break out, yelling “FIRE!” isn’t enough. Your site should have an alarm

Planning for Prevention

Demolition work? You need charged hose lines and a written fire plan before you even start. And if you’re storing combustible materials outside, keep piles 20 feet away from buildings, mow the grass, and keep access roads clear.

A Final Word (Before the Fireworks Start)

Whether it’s battery charging, temporary heating, or just storing gas cans the right way, fire safety comes down to attention, intention, and integrity. If it’s not safe, we don’t build it. If it doesn’t feel right, we fix it.

As we gear up for a weekend of backyard barbecues, fireworks, and family time, let’s carry that same care back to the jobsite on Monday. Because at Morcon, fire safety isn’t seasonal—it’s part of the foundation we build on.

Happy Fourth of July, and stay safe out there. 🇺🇸
