Two dozen Amazon warehouse employees in New Jersey were hospitalized Wednesday, one in critical condition, after a robot punctured a can of bear repellent, according to local reports. The news was soon picked up by national outlets and spread on social media, in part because it’s a perfect horror story for the year of our lord 2018.

In total, 54 workers at the Robbinsville, New Jersey, facility were exposed to fumes. Bear repellent is made with capsaicin, or chili pepper extract; many of the workers experienced trouble breathing and said their throats and eyes burned. All of the injured workers are expected to be released from hospitals soon, if they haven’t been already, according to Rachael Lighty, a spokesperson for Amazon. “The safety of our employees is always our top priority,” she said in a statement. The Occupational Safety and Health Administration says it is conducting an investigation into the incident.

Wednesday’s mishap demonstrates the many hazards that workers must contend with in Amazon’s sprawling warehouses, where almost every product imaginable may be in stock—including aerosol cans of irritating spray for warding off bears. This particular accident comes with an added dystopian layer, since it was caused by one of the robots Amazon hopes will replace many of its human warehouse workers in the near future.

But things get much stranger when you realize this isn’t the first time a can of bear repellent has exploded in an Amazon facility. In 2015, the fire department responded to an accident at an Amazon facility in Haslet, Texas, that was caused by a robot running over a can of none other than bear repellent, according to public records unearthed by Jessica Bruder for her book Nomadland, which chronicles the lives of the retail giant’s older, transient workforce.

The New Jersey incident wasn’t even the first bear repellent accident at an Amazon facility in 2018! One employee at an Amazon warehouse in Indiana told WIRED that a can ruptured in his facility earlier this year. The worker says that accident was caused by someone dropping the can, and they believe no injuries occurred. They think the way the product is packaged may be the issue; the employee adds that they, too, have dropped the repellent, though in their case it didn’t rupture. “It’s a clamshell that pops open when you pick it up,” the employee says. “What I can say is that our safety people are on it, and they are top-notch.”

Lighty, the Amazon spokesperson, confirmed in an email that an incident involving bear repellent did occur at the Indiana facility earlier this year. She also confirmed the 2015 accident in Texas. However, she added, "I do not have exact information on the root cause of either scenario, only that they were different."

It’s not just bear spray that can cause issues at Amazon. The mishap this week in New Jersey affected a particularly large number of people, but bizarre and tragic accidents happen at the company’s facilities on a regular basis, some more serious than others. In November, two Amazon contractors were killed when a wall inside a distribution center in Baltimore collapsed during a bad storm. Seven months earlier, two people suffered minor injuries at a facility in Ohio after a tornado ripped open a 100-foot hole in the roof. In September 2017, an employee at an Amazon warehouse in Pennsylvania was run over by a truck and killed.

Accidents happen often at Amazon in part because it’s one of the largest employers in the US. Fatal occupational injuries have also been on the rise across the country, according to the Bureau of Labor Statistics. Amazon does employ onsite medical contractors, at least at some facilities, according to another employee who works at an Amazon warehouse on the East Coast. They are equipped to provide basic medical care in the case of minor illnesses and injuries. The worker said that a handful of medical staff work each shift at their facility.
