Pink flame retardants - what do we know about them?



 “Yeah. They’ve got a couple water sources, so she might be on the hose. I know they dropped mud on her earlier.” 

 “Why would they drop mud on Rowan?” 

 His laugh broke out, long, delighted. 

“Sorry. I meant the fire. Mud’s what we call the retardant the tanker drops. 

Believe me, no smoke jumper wants to be under that.”

Aircraft battling fires raging through the Los Angeles area are dropping more than water: Hundreds of thousands of gallons of hot-pink fire suppressant ahead of the flames in a desperate effort to stop them before they destroy more neighborhoods.

 “Why pink? It’s kind of girlie.” 

 He grinned as she got out a skillet. 

“They add ferric oxide to make it red, but it looks like pink rain when it’s coming down. 

The color marks the drop area.”

'Catastrophic' bushfires hit Sydney




“Take cover!” she shouted to her team. “We’re good, Gibbons. Tell them to drop the mud. We’re clear.”
Through the smoke, she watched the retardant plane swing over the ridge, heard the thunder 
of its gates opening to make the drop, and the roar as the thick pink rain streaked down from the sky.

“You don’t want to hear about mud.”
“You’re wrong,” she told him as they gathered up the tray,
 the glasses, the wine. “I’m interested.”
“It’s thick pink goo, and burns if it hits your skin.”
“Why pink? It’s kind of girlie.”
He grinned as she got out a skillet. “They add ferric oxide

Brazil's Amazon rainforest is burning





Dobie pulled a smashed sandwich out of his bag, 
looked up at the towering columns of smoke and flame. 
“Biggest I’ve ever seen.”
“She’s a romper,” Rowan agreed, “but you know what they say 
about Alaska. 
Everything’s bigger. 
Fuel up. We’ve got a long way to go.”

Fires are raging at a record rate in Brazil's Amazon rainforest, and scientists warn that it could strike a devastating blow to the fight against climate change.

The fires are burning at the highest rate since the country's space research center, the National Institute for Space Research (known by the abbreviation INPE), began tracking them in 2013, the center said Tuesday.

School That Turns Firefighters Into Fire Detectives






“Regardless, we’ll pursue every avenue of the investigation. We can speculate, too, Mr. Curry,” DiCicco added. “But we have to work with facts, with data, with evidence. Two people are dead, and that’s priority. But those wildfires matter. I work for the Forest Service, too. Believe me, it all matters.”

When a wildfire stops burning, an important job begins: Figuring out how it started, and who should be held responsible.











________________







And while he performed these habitual acts, he scanned the scene. A man in his position needed to keep an open mind about fire. He would take an overview of the scene, the weather, note the wind direction, talk to the fire fighters. There would be all manner of routine and scientific tests to run.
But first, he would trust his eyes, and his nose.
The warehouse was most probably a loss, but it was no longer his job to save it. His job was to find the whys and the hows.
He exhaled smoke and studied the crowd.
He knew the night watchman had called in the alarm. The man would have to be interviewed. Ry looked over the faces, one by one.

Forest Fires Make Their Own L-ish Weather






“Hey, Swede.” Gibbons, acting as fire boss, hailed her over the din. 
Ash blackened his face, and the smoke he’d hiked through 
reddened his eyes. “I’m taking you, Matt and Yangtree off the saw line. 
The head’s shifted on us. It’s moving up the ridge to the south and building. 
We got spots frigging everywhere. We need to turn her while we can.”
He pulled out his map to show her positions. “We got hotshots working here, 
and Janis, Trigger, two of the rooks, flanking it here. 
We’ve got another load coming in, and they’ll take
the saw line, chase down spots. We’ve got repellent on the way, 
should dump on the head in about ten, so make sure you’re clear.”
“Roger that.”
“Take them up. Watch your ass.”
She grabbed her gear, pulled in her teammates and began the 
half-mile climb through smoke and heat. In her mind she plotted 
escape routes, the distance and direction to the safe zone.

The most useful thing scientists can tell a fire crew in the field is what the fire's going to do. And that means understanding how the winds may shift—even when they come from the fire itself.

She felt the change in the wind, just a flutter, and saw the fire grab its tail to ride. A cut to the
west now, still north of Trigger’s crew, she noted, but moving toward them.
She circled around, contacting him by radio.
“She’s shifting, curling back toward you.”
“We’ve got a Cat line here, a good, wide one. I don’t think she can jump it. Escape route due
south.”
“They’re bringing mud. I just called to tell them to dump a load west, down your flank. Stay
clear.”
“Roger that. Cards just got here with reinforcements. We’re going to hold this line, Swede.”
“After the mud drops, I’m going to get an air report. I want to take four from your team, same
from mine, get them up to the head. Squeeze it. But if she jumps the road, get gone.”

Chasing Fire



  It screamed, Rowan thought as she tore the protective case off her fire shelter, shook it out. Or Matt screamed, but a madman with a gun had become the least of their problems.

  She stepped on the bottom corners of the foil, grabbed the tops to stretch it over her back. Mirroring her moves, Gull sent her a last look and shot her a grin that seared straight into her heart.

  “See you later,” he said.

  “See you later.”

  They flopped forward, cocooned.

  Working quickly, Rowan dug a hole for her face, down to the cooler air. Eyes shut, she took short, shallow breaths into the bandanna. Even one breath of the super-heated gases that blew outside her shelter would scorch her lungs, poison her.
  The fire hit, a freight train of sound, a tidal wave of heat. Wind tore at the shelter, tried to lift and launch it like a sail. Sparks shimmered around her, but she kept her eyes closed.

Firefighter owes life to fire shelter

 

Although the shelters saved his life twice, Rodriguez said he well knows the uncertain protection they provide.


"You don't want to rely on your fire shelter to get you through something," Rodriguez said. "It is a last resort. It's when all else has failed."


How well such shelters work depends on factors such as the terrain where they're used and how long the fires burn on top of them, Rodriguez said. His fallen colleagues were never able to reach an appropriate surface where they could deploy their shelters.


"They're designed to deflect radiant heat," Rodriguez said. "You do absorb some on the inside. But it all depends on where you're at, where you deploy them. You have to wait it out."


Getting through the fire also depends on staying calm as the heat and smoke rage outside, he said.

Dizzy, she realized, sick. Too much heat. Can’t pass out. Won’t pass out. As she regulated her breathing again, she realized something else.
  Quiet.
  She heard the fire, but the distant snarl and song. The ground held steady under her body, and the jet-plane thunder had passed. 

  She was alive. Still alive. 

  She reached out, laid a hand on her shelter. Still hot to the touch, she thought. But she could wait. She could be patient. 

And if she lived, he’d damn well better live, too.
