20 Jobs from the Past That Were Practically a Death Sentence

Children were sent into narrow, soot-encrusted chimneys to sweep them, because their small size allowed them to squeeze through where adults could not fit. This job was synonymous with burns, falls, suffocation, lung damage, and a lifetime spent breathing in coal soot—all before anyone really cared about protecting the children who did it. 

Match manufacturing seems like a delicate process—until you get to white phosphorus. In the 19th century, workers in the match industry could contract “phosphorus jaw,” a terrible occupational disease that attacked the jawbones and turned a simple factory job into a slow-moving medical nightmare. 

Painting watch dials with radium was presented as clean, skilled work intended for young women, which makes the betrayal all the more cruel. The workers were asked to sharpen the radioactive brushes with their lips, thereby silently exposing them to radiation as they painted watch dials that glowed magically in the dark. 

"Powder monkeys" were usually young boys on board warships, small and agile enough to carry gunpowder from the powder magazine to the cannons during battle. A spark, a blow, a moment of inattention—and this task could go from being a simple job to causing an explosion. 

Coal mining has always involved very real dangers: cave-ins, explosions, poor air quality, flooding, and dust that accumulated in the lungs. Day after day, the men went underground knowing that the ground above them could collapse at any moment.

The young sorters would sit near the conveyor belts and separate slate from coal—often while they were still just children—breathing in the dust as their hands worked frantically beside the machines. It was the kind of work that first robbed them of their childhood, then their health, and sometimes even their fingers. 

Miners dug tunnels and built the foundations of bridges under rivers, working in a high-pressure environment where the body could turn against itself. Caisson disease, later known as “caisson sickness,” made returning to the surface dangerous in itself, as ascending too quickly could cause irreversible damage or even death.

Sewage workers used to empty septic tanks, latrines, and old-fashioned toilets before modern sewer systems took over to handle the worst of it. This work was as repulsive as it sounds, but the real danger lay in the risk of infection, foul air, cave-ins, and daily contact with everything a city preferred to keep hidden. 

The “toshers” scoured London’s sewers in search of anything valuable enough to sell. They worked in darkness, filth, and treacherous waters, earning their living in places where a single misstep could lead to illness, drowning, or simply never being found in time. 

From the outside, hat-making seemed like a respectable trade, but inside the workshop, the materials could insidiously poison those who handled them. Hatsmakers exposed to mercury could develop tremors, speech impairments, mood swings, and neurological damage—which partly explains the sinister origin of the expression “crazy as a hatsmaker.” 

Leech collectors met the medical community’s demand for bloodletting by wading through the marshes and letting leeches attach themselves to their own legs. This work involved blood loss, infections, cold water, and the strange humiliation of being both a laborer and bait. 

Tanners transformed animal hides into leather, which forced them to live amid rotting hides, corrosive liquids, scraping tools, and odors so foul that this trade had been banished to the outskirts of the city. It was an indispensable job, but also a filthy, corrosive, and physically grueling one, the marks of which never faded. 

Workers in the powder magazines had to exercise a level of caution that most other trades never require. A single mistake, a spark, a bit of friction, or a moment of inattention could reduce a building to ashes, making every workday feel as if it were on the verge of exploding. 

Whaling involved small boats, gigantic animals, freezing seas, sharp tools, and slippery decks covered in oil and blood. Even before considering storms or shipwrecks, the mere act of hunting and butchering whales exposed the workers to many different ways of dying. 

Workers exposed to lead were handling a material that was used everywhere, but the dangers of which were recognized far too late. Mining it, smelting it, using it for painting, or shaping it could lead to chronic poisoning, the effects of which developed so slowly that employers were unaware of them and workers bore the consequences. 

Asbestos once seemed like a miracle material, especially when it could be spun, woven, and turned into fire-resistant products. It was the people who handled these fibers who paid the highest price, inhaling dust that could cause asbestosis, lung cancer, or mesothelioma years later. 

During epidemics, someone had to collect the bodies, dig graves, and walk the streets that everyone else was trying to avoid. This work involved exposure to danger, exhaustion, grief, and the grim realization that the public good often entailed personal risk.

Ice cutters were hard at work on frozen rivers and ponds before the advent of refrigeration put an end to this trade. They used saws, hooks, horses, and their own physical strength on unstable surfaces, where a single misstep could send a worker through the ice instead of keeping him on the surface.

Pearl divers made this beauty possible by repeatedly diving into the depths, with little protection and no guarantee of ever returning to the surface. This work involved holding one’s breath for too long, enduring the pressure on the body, brushing against sharp coral, battling violent currents, and facing the constant risk of drowning—all for an object so small it could disappear in the palm of a hand.

Rope access workers scaled towers, chimneys, bell towers, and factory smokestacks with nothing to rely on but their composure, their tools, and their trust in the ladder or rope at their disposal. In this line of work, gravity seemed like a vindictive colleague, and a single misstep could end an entire career in a matter of seconds.
