Asbestos Textiles: Cloth, Garments, Gloves, and Blankets

Asbestos textiles were the gear that stood between a worker and the heat: the gloves for handling hot metal, the blankets thrown over a weld, the coats and hoods worn at the furnace, and the cloth, tape, and rope wrapped around anything that ran hot. The danger was that the protection itself shed fiber every time it was handled. Clapping the dust out of a pair of worn asbestos gloves has been measured at 47.6 fibers per cubic centimeter, which in fifteen minutes puts roughly fourteen years' worth of ordinary city background air through a worker's lungs¹, and that was a gesture workers made without a thought, dozens of times a week, for years. You don't need to remember which brand of gloves hung by the furnace or dig up any old records to find out whether you have a claim; if you wore or handled this gear at work, that's where we start.

Even ordinary city air carries a faint trace of asbestos everywhere, from natural mineral erosion and decades of industrial use, and that trace is the baseline both sides of the panel are measured against.

What these numbers mean. Asbestos in air is measured in fibers per cubic centimeter (f/cc), a unit that hides how dangerous a task was. Across this site we translate each measurement into fibers breathed, feet of fiber end to end, and years of ordinary city air, using conservative, government-sourced assumptions. See how we measure asbestos in air for the method and its limits.

What asbestos textiles were

Asbestos is a mineral, but its fibers are long and flexible enough to be spun and woven like wool, and that single property built an entire product category. Mills carded raw fiber into roving (loosely twisted strands ready for spinning), spun the roving into yarn, and wove the yarn into cloth, and from that cloth the industry cut and sewed nearly everything that had to survive heat: gloves and mitts for handling hot metal, aprons and leggings for pouring and casting, coats and hoods for furnace work, blankets and curtains for welding, and pads for stress-relieving welds on pipe.

Alongside the sewn goods came the woven and twisted forms sold by the roll and the coil. Asbestos cloth wrapped pipes, boilers, and wiring runs. Woven asbestos tape, sold in narrow rolls, wrapped joints, hoses, and electrical work. Asbestos rope and wick packed the doors of ovens, kilns, and boilers, and sealed the seams that gaskets couldn't reach. Much of it ran to very high asbestos content, because the mineral was the point; the cotton or other carrier fiber was there only to help the weave hold together.

Representative products and their asbestos content. These are examples, not a full list:

Notice what those percentages mean. A product that is 95% asbestos isn't a material with some asbestos in it; it's asbestos, held together by a thread of something else. Textiles were overwhelmingly a chrysotile (white asbestos) category, because chrysotile is the form whose fibers spin and weave well, and we present that point honestly rather than blurring it: chrysotile is classified by IARC as a Group 1 human carcinogen and is a recognized cause of mesothelioma⁵. The case for these products doesn't need any overstatement about fiber type; it rests on what the woven mineral did in the air when people handled it.

How asbestos textiles put asbestos in the air

A new asbestos glove or blanket looks like a solid piece of fabric, and the industry leaned on that impression for decades. But a weave isn't a seal. Every flex of the fabric works fibers loose, heat dries and embrittles the material, and wear frays the surface into a nap of exposed fiber. The dust that built up on and in the gear then came out the way dust always comes out of fabric: by handling it. Clapping gloves together to knock the grit off, shaking out a blanket after a weld, folding and unfolding a curtain, and cutting or tearing cloth and tape to length all released fiber directly at face height, in the breathing zone, which is the air right where a worker actually inhales.

Here is what that handling measured. Each figure is a phase-contrast (PCM) measurement, which counts only the longer fibers and so reads as a floor, not a ceiling:

The pattern in that table is the whole story of this product. The worn gloves read twice as high as the good ones, because wear is exactly what turns a woven product into a fiber source, and no glove on a working shop floor stayed in good condition for long. The gear got used until it fell apart, and it shed the entire time.

By the illustrative math on our how we measure asbestos in air page, 15 minutes of clapping the dust out of worn gloves put roughly 14 years of ordinary city air through the lungs. This estimates fibers in the air breathed, not a retained dose.

The full task-by-task story of who wore this gear and where, from the welding bay to the furnace floor, lives on the occupation and industry pages linked below. What belongs here is the product itself and the fact that its danger was built into how it had to be used: worn on the body, handled by hand, and cleaned by shaking.

What the makers knew

The documented record on asbestos textiles has a bitter through-line: the very gear sold to keep workers safe from heat was itself putting fiber into their air, and that fact was measured and published, not guessed at.

The work-practice literature recorded it directly. A 1992 Millette/MVA study of glove handling recorded peak short-duration exposures reaching 47.6 f/cc from nothing more than clapping the dust out of a worn pair¹. Hatfield and Longo at Materials Analytical Services documented in 1999 that just six minutes of routinely shaking out a single welding blanket generated substantial breathing-zone fiber². And the measurements reach back further still: Gibbs measured workers in 1975 simply for wearing asbestos coats, hoods, and gloves around blast furnaces, treating the protective clothing itself as the exposure source under study³. Wearing the gear was an exposure; handling and cleaning it was a heavy one; and the literature said so for decades.

That record matters legally as well as historically. These weren't exotic laboratory conditions; the studies measured the ordinary, intended use of the products, the exact handling every manufacturer knew its gloves and blankets would receive on a shop floor. A hazard documented in the published literature of the industry is a hazard the makers are charged with knowing, and the workers wearing the gear were told the opposite: that this was the safety equipment.

Who was exposed

Asbestos textiles weren't tied to one trade; they were issued wherever work ran hot. Rather than retell each worker's story here, this page hands that off to the pages that own it:

• welders, who worked under and beside asbestos blankets, gloves, and heat garments every day
• steelworkers and foundry workers, whose furnace and pouring work meant asbestos coats, hoods, mitts, and leggings
• electricians, who cut and wrapped asbestos cloth and woven tape around wiring, connections, and heat-prone equipment

If you or your family member wore heat gear or handled asbestos cloth in any of these settings, the exposure history is usually easy to reconstruct.

The manufacturers and the trusts

Recovery in a textile case runs mostly through the asbestos bankruptcy trusts, because the major makers of asbestos cloth, garments, and blankets went bankrupt under the weight of these claims, and the trusts they funded pay claims today through a paper process with no lawsuit. Depending on where the gear was worn, the site owner can also be reached as a premises defendant, and one pathway doesn't reduce another.

A §524(g) trust, named for the bankruptcy-code section that creates it, is a fund a bankrupt asbestos company sets aside to pay present and future claimants; filing against one is a documentation process, not a courtroom fight. If the idea of any lawsuit is uncomfortable, you're in good company; Clarence Borel, the refinery insulator whose 1973 case built the modern asbestos-litigation system, didn't want to sue either, and we can pursue trust claims alone if that's your preference.

Sources of compensation

A textile case usually draws from several sources at once, and they run in parallel:

• Asbestos bankruptcy trusts. The makers who went bankrupt set aside money to pay the people they harmed. These are paper claims, with no lawsuit and no courtroom, and one career in heat gear often supports filings against several trusts. How asbestos trust claims work.
• Lawsuits against solvent companies. Where a responsible company never went bankrupt, it can be sued directly, and those tort recoveries often exceed what a trust pays per claim. How product liability lawsuits work.
• Premises liability against site owners. The mills, foundries, shipyards, and plants that issued the gear and controlled the worksite can be held responsible for the conditions they allowed. How premises liability claims work.
• Federal and disability benefits. Navy service can support VA disability benefits, and civilian shipyard work can support Longshore (Longshore and Harbor Workers' Compensation Act) benefits, both paid in addition to the rest. How asbestos disability and benefit claims work.

The defendants in textile cases lean on the fabric itself, arguing that a woven product is a contained product. None of it is new to us. All of this applies only to the lawsuit side. Trust claims are a paper process: no opposing lawyer raises defenses, no one is deposed, and no one goes to court.
