Episode 26 — The Shipyards Never Sleep

“The first time I walked out on the ways, I was walking into a kind of nightmare of sounds, noise, and smells.” Howard Zinn was nineteen years old when he walked through the gates of Brooklyn Navy Yard in December 1941. He’d later become one of America’s most influential historians. But first, he’d spend years crawling into four-by-four-by-four-foot compartments so full of asbestos dust that workers couldn’t see across them.

By December 1943, 1.7 million shipyard workers labored around the clock — three shifts, twenty-four hours a day, seven days a week. Each Iowa-class battleship contained 465 long tons of asbestos insulation. Each destroyer: 85,000 to 90,000 pounds. Over 5,500 ships built between 1939 and 1945. One Navy memo from 1944 called the dust concentrations “a dangerous hazard to personnel.” It never reached the workers on the floor. They thought the dust dissolved when they breathed it in — like sugar in water.

Key Takeaways

• 465 long tons of asbestos insulation per Iowa-class battleship. Eighty-five thousand to ninety thousand pounds per destroyer. Over 5,500 vessels built 1939–1945 — Liberty ships, Victory ships, destroyers, battleships — each one packed with asbestos and built by workers who had no idea what they were breathing.
• Three shifts. Twenty-four hours. Seven days a week. At Brooklyn Navy Yard, 70,000 workers per day at peak production. Forty percent were logging more than 48 hours a week by 1942. The time-weighted averages industrial hygienists later used to define “safe” exposure were meaningless for workers logging 60–70-hour weeks in asbestos dust.
• Every trade was exposed. Pipe coverers handled felt insulation that was 85–95% asbestos by content. Welders wore asbestos gloves, aprons, leggings, and blankets. Boilermakers worked in compartments where insulators had just been. Electricians handled asbestos wire insulation. Carpenters cut Transite board (asbestos-cement). Court records: “Asbestos was essentially everywhere.”
• The 1944 Navy Bureau of Medicine letter. Dust counts during amosite felt insulation application were “well above the accepted maximum of eight million particles of dust per cubic foot.” Conclusion: “a dangerous hazard to personnel.” Written in 1944. Workers on the shipyard floor: never informed.
• Clarence Borel’s testimony. Industrial insulation worker, 33 years (1936–1969). Under oath: “I blowed this dust out of my nostrils by handfuls at the end of the day.” He thought it was “bothersome.” He “never realized it could cause any serious or terminal illness.” He believed the dust “dissolves as it hits your lungs.” He learned the truth in January 1969. He died June 3, 1970 — four months later. His case became Borel v. Fibreboard, the landmark asbestos liability decision.
• The information gap. 1930: British science establishes asbestos causes asbestosis. 1938: U.S. Public Health Service sets a 5-million-particle safe limit. 1941: Stephenson warns Admiral McIntire that “we are not protecting the men as we should.” 1944: Navy documents “dangerous hazard to personnel.” Workers’ knowledge throughout: the dust dissolves.
• 30% of all mesothelioma diagnoses are veterans. Nearly 1,000 shipyard and Navy cases annually. The 20–50-year latency clock meant executives who signed the 1944 memos were retired before workers started dying. Cases from 1940s wartime exposure are still being diagnosed today.

S1E26: The Shipyards Never Sleep

Series: Asbestos: A Conspiracy 4,500 Years in the Making  |  Arc 6: The War Effort  |  Era: December 1941 – December 1943 (consequences to present)

Key Takeaways

• 1.7 million workers labored in WWII shipyards where asbestos dust was so thick workers "couldn't see across rooms"
• An Iowa-class battleship contained 465 long tons of thermal insulation; a destroyer contained 85,000–90,000 pounds
• The Navy Bureau of Medicine documented "dangerous hazard to personnel" in 1944 — workers were never warned
• Workers believed asbestos dust "dissolved" in their lungs — Clarence Borel learned the truth only 4 months before his death
• Today, 30% of all mesothelioma diagnoses are veterans, with ~1,000 shipyard/Navy cases annually
• Howard Zinn, author of "A People's History of the United States," was an apprentice shipfitter at Brooklyn Navy Yard in December 1941

Episode Summary

Episode 26 covers the American shipyard mobilization of World War II — the largest industrial buildout in history — and how 1.7 million workers were exposed to catastrophic concentrations of asbestos while Navy medical officers documented the hazard in classified memos. The episode traces three parallel threads: the scale of asbestos use per vessel (465 long tons on a battleship), the internal Navy documentation of the danger (culminating in the 1944 Bureau of Medicine "dangerous hazard" letter), and the lived reality of workers like Clarence Borel who believed the dust dissolved in their lungs. The episode closes on Larry Gates — whose father died of mesothelioma from refinery exposure — and bridges to Episode 27 on the women of the shipyards.

Cold Open: Howard Zinn's Testimony

Host 1: December 1941. Brooklyn Navy Yard. Howard Zinn is nineteen years old. An apprentice shipfitter. His first day on the job.

Host 2: Howard Zinn. The historian.

Host 1: The historian. But right now he's just a kid walking through the gate for the first time. Here's how he described it, decades later, in an oral history interview.

Host 2: Okay.

Host 1: "The first time I walked out on the ways, I was walking into a kind of nightmare of sounds, noise, and smells."

Host 2: A nightmare.

Host 1: "The smells of working on a ship are amazing smells. The smells of the welding, especially when they were welding galvanized steel. Galvanized steel is covered with zinc. And when zinc burns, it gives off the worst smell in the world."

Host 2: And that's just the welding.

Host 1: "In the summer it was very, very hot. Because we were wearing protective clothing. They gave us salt pills in the summertime. Because we were sweating, sweating."

Host 2: Salt pills.

Host 1: "And we were sweating not only because of the heat but because a lot of our job required us to crawl into the hull into these little compartments which were four by four by four."

Host 2: Four feet by four feet by four feet.

Host 1: "Which had a little hole through which you could go into this four by four by four compartment to work." That's where they built ships. That's where they built the fleet that won the war. And that's where one point seven million Americans breathed in dust that wouldn't kill them for twenty years.

Host 2: This is Asbestos: A Conspiracy 4,500 Years in the Making. Episode 26: The Shipyards Never Sleep.

The Scale of the Buildup

Host 1: After Pearl Harbor, American shipyards didn't sleep. Three shifts. Twenty-four hours a day. Seven days a week.

Host 2: For how long?

Host 1: For the duration. At Brooklyn Navy Yard alone, seventy thousand people reporting for work each day at peak production. The yard was a city unto itself.

Host 2: Three shifts. So workers coming in at—

Host 1: Day shift starting at six or seven AM. Swing shift at two or three PM. Graveyard starting at ten or eleven at night.

Host 2: And the insulation work — the asbestos work —

Host 1: Happening around the clock. A day-shift worker might enter a compartment that had been filled with asbestos dust by the night shift. By the swing shift before that. The dust didn't clock out.

Host 2: And overtime?

Host 1: Bureau of Labor Statistics records show that by 1942, forty percent of Brooklyn Navy Yard workers were logging more than forty-eight hours a week. President Roosevelt extended working hours for war industries in February 1943.

Host 2: More hours, more exposure.

Host 1: More hours, more exposure. And the time-weighted averages that industrial hygienists would later use to calculate "safe" exposure? Meaningless. Because the workers were in it for sixty, seventy hours a week.

The Trades and What They Breathed

Host 1: Let's talk about who was actually handling the asbestos. And what they were handling. First — the pipe coverers. The insulators. The workers applying asbestos directly to pipes, boilers, turbines.

Host 2: The highest exposure.

Host 1: The highest exposure. At shipyards like Bath Iron Works in Maine, there were dedicated pipe covering shops. Dr. Philip Drinker — Harvard professor, Chief Health Consultant to the Navy — surveyed them in 1944. His finding: workers cutting and pounding asbestos matting in conditions that created "a very real asbestos hazard."

Host 2: What were they cutting?

Host 1: Felt insulation. Asbestos content: eighty-five to ninety-five percent.

Host 2: That's not insulation with asbestos. That's asbestos with insulation.

Host 1: Exactly. And in some shipyards — Brooklyn, for example — there were asbestos mixing rooms. Workers combining raw asbestos fibers with magnesia, mixing them by hand.

Host 2: By hand.

Host 1: By hand. Then there were the boilermakers. They weren't applying insulation directly, but they were working in the confined spaces where insulators had just been. Or where insulators were working alongside them. Court testimony describes it: "In the naval shipyards, workers of all trades in small compartments breathed the heavy asbestos dust created by insulators and boilermakers."

Host 2: "Heavy asbestos dust in small compartments."

Host 1: Now add the welders.

Host 2: How were welders exposed? They weren't handling insulation.

Host 1: They were wearing it. Asbestos welding gloves. Asbestos aprons. Asbestos leggings. Asbestos blankets used as fire shields. And more than that — welders worked in the same confined spaces as insulators. They welded near freshly-applied insulation.

Host 2: So the protective gear was asbestos, and the environment was asbestos.

Host 1: And then the electricians — asbestos wire insulation, asbestos electrical tape. The carpenters — cutting asbestos-cement panels. Transite board. The machinists — brake and clutch materials. Gaskets. The reality, documented in court records: "Asbestos was essentially everywhere."

Host 2: How much asbestos are we actually talking about? Per ship?

Host 1: An Iowa-class battleship. Four hundred sixty-five long tons of thermal insulation.

Host 2: Four hundred sixty-five tons.

Host 1: A destroyer. Eighty-five thousand to ninety thousand pounds of thermal insulation alone. Not counting pipe hanger liners, gaskets, electrical cables. And how many ships were built? The Maritime Commission program built over five thousand five hundred vessels between 1939 and 1945. Liberty ships: two thousand seven hundred ten. Victory ships: five hundred thirty-one. Each one packed with asbestos. Each one built by workers who would carry the fibers home in their lungs.

Host 2: So that's the exposure.

Host 1: Now let's look at what officials were writing — during the same years, in the same shipyards.

Host 2: We covered some of this last episode. The Stephenson memo. Commander warning the Surgeon General that "we are not protecting the men as we should."

Host 1: March 1941. Before Pearl Harbor. But it didn't stop. 1944. Dr. Drinker reports to the Navy Bureau of Ships that dust counts at Bath Iron Works were "very much higher than anyone would recommend."

Host 2: And the Navy's response?

Host 1: A 1944 letter from the Navy Bureau of Medicine to the Supervisor of Shipbuilding. The Bureau had conducted dust counts during application of amosite felt insulation. Their finding: concentrations "well above the accepted maximum of eight million particles of dust per cubic foot."

Host 2: What was the accepted maximum?

Host 1: The U.S. Public Health Service had established a threshold of five million particles per cubic foot back in 1938. The Navy used eight million as their maximum. The shipboard measurements were well above that.

Host 2: And their conclusion?

Host 1: "A dangerous hazard to personnel." In 1944. While one point seven million workers were laboring in those conditions.

What the Workers Knew: Clarence Borel

Host 1: So that's what the Navy knew. What Drinker documented. What the Bureau of Medicine wrote in internal correspondence. Now let's talk about what the workers knew.

Host 2: They knew the dust was there. They couldn't not know — you couldn't see across the rooms.

Host 1: They knew it was there. They didn't know what it was doing to them. Clarence Borel. Industrial insulation worker. Thirty-three years, 1936 to 1969. Shipyards and refineries along the Texas-Louisiana border. His deposition testimony — given under oath, in the lawsuit that would change asbestos law forever — describes what he believed about the dust.

Host 2: Okay.

Host 1: "You just move them just a little and there is going to be dust, and I blowed this dust out of my nostrils by handfuls at the end of the day."

Host 2: By handfuls.

Host 1: "Trying to use water too. I even used Mentholatum in my nostrils to keep some of the dust from going down in my throat, but it is impossible to get rid of all of it."

Host 2: So he knew he was breathing it. Every day.

Host 1: Every day. For thirty-three years. And here's what he believed about what it was doing to him. He thought the dust was "bad." He thought it was "bothersome." But — and this is his sworn testimony — he "never realized it could cause any serious or terminal illness."

Host 2: He didn't know it could kill him.

Host 1: He didn't know it could kill him. And here's the part that broke me. When asked what he thought happened to the dust once he breathed it in, Borel said he believed it "dissolves as it hits your lungs."

Host 2: He thought it dissolved.

Host 1: He thought it dissolved. Like sugar in water. Like it just... went away. That's what the workers believed. The dust that was coating their lungs, embedding in their tissue, starting the twenty-year clock toward mesothelioma — they thought it dissolved.

Host 2: Nobody told them otherwise?

Host 1: Borel's testimony is explicit on this point. No one — not employers, not manufacturers, not the Navy — ever told him asbestos dust could cause fatal disease. He learned about asbestosis in January 1969, when he was hospitalized with breathing problems. February 1970, they removed his right lung. Found mesothelioma. He died June 3, 1970. Four months after learning what the dust had actually done.

Host 2: Thirty-three years of exposure. Four months of knowing the truth.

Host 1: And Borel wasn't unique. He was typical. The New York Times would later report that during World War II, asbestos dust clouded shipyards so thickly that "one often could not see across the rooms they worked in." One point seven million workers. And they thought the dust dissolved.

Host 2: That's what they walked into. Every day. For years.

Host 1: Let's put the timeline side by side. 1930: Merewether and Price establish, in the British medical literature, that asbestos causes asbestosis. 1935: Sumner Simpson writes that "the less said about asbestos, the better off we are." 1938: U.S. Public Health Service establishes five million particles per cubic foot as the safe limit. 1939: Navy Medical Officer H.E. Jenkins recommends respirators for shipyard workers. 1941: Commander Stephenson warns Admiral McIntire that "we are not protecting the men as we should." 1943: Navy issues safety standards calling for ventilation, respirators, medical exams. 1944: Navy Bureau of Medicine documents shipboard dust concentrations as "a dangerous hazard to personnel."

Host 2: That's the official record.

Host 1: And during the same years — 1941 to 1945 — one point seven million workers labor in conditions so dusty they can't see across rooms. They blow asbestos out of their nostrils by handfuls. They wear protective gear made of asbestos. They crawl into four-by-four-by-four compartments filled with asbestos dust. And they think it dissolves.

Host 2: How is that possible? The Navy knew. The standards existed.

Host 1: The information never reached the workers. Navy medical officers documented hazards in internal memos. The memos went up the chain of command. The workers on the shipyard floor saw nothing.

Host 2: So when workers started dying twenty years later—

Host 1: —the executives who signed the memos would be retired or dead. The workers would be grandfathers, wondering why they couldn't breathe. And the paper trail would be buried in corporate archives.

Host 2: The latency clock.

Host 1: Twenty to fifty years between exposure and diagnosis. The workers exposed in 1943 wouldn't develop disease until 1963 at the earliest. Today, thirty percent of all mesothelioma diagnoses are veterans. Nearly a thousand shipyard and Navy cases diagnosed every year.

Host 2: The shipyards built the fleet that won the war.

Host 1: And they poisoned a generation.

Larry Gates and the Veterans Who Came After

Host 2: Which is why this matters. Larry Gates grew up three blocks from the Shell refinery in Pasadena, Texas.

Host 1: The Golden Triangle.

Host 2: His father was a chemical operator. Instrument technician. Worked at Shell for years — exposed to asbestos throughout the plant.

Host 1: In his twenties and thirties, when the exposure was heaviest.

Host 2: And then?

Host 1: 1999, his father was diagnosed with mesothelioma. Dead six months later. Larry's words: "I watched him wither away from a strong, active man into a skeleton."

Host 2: And now Larry's Senior Client Advocate at Danziger and De Llano, helping families navigate VA claims and trust fund compensation.

Host 1: He's seventy-two. Currently fighting his own battle with cancer.

Host 2: When he talks to families, he's not reading from a script. He's lived both sides — as a son who lost his father, and as someone fighting the same industrial disease.

Host 2: Dan-Dell dot com. That's D-A-N-D-E-L-L dot com.

Host 1: That's the men's story. The pipe coverers, the boilermakers, the welders, the electricians. One point seven million workers at peak production. Every one of them walking into the dust.

Host 2: But they weren't the only ones exposed.

Host 1: No, they weren't. Because starting in 1942, there was another workforce flooding into the shipyards. Women.

Host 2: Rosie the Riveter.

Host 1: By 1943, women made up thirteen percent of shipyard production workers. Thirty thousand in Portland alone. Seven thousand at Brooklyn Navy Yard. They did the same jobs. They worked in the same conditions. And when the war ended and they went home—

Host 2: —their husbands kept working. Bringing the dust home on their clothes.

Host 1: Next episode: The Women of the Shipyards. The exposure that happened on the factory floor — and the exposure that happened at the wash basin.

Host 2: Until next time. This has been Asbestos: A Conspiracy 4,500 Years in the Making.
