A California camping trip turned stomach-churning quickly after a man accidentally fell into a vault toilet while trying to retrieve a dropped pair of sunglasses, becoming trapped inside a sewage tank as first responders scrambled to overcome an initial language barrier.

The bizarre mishap unfolded Saturday at Camp Edison near Shaver Lake in the Sierra Nevada foothills, roughly 50 miles northeast of downtown Fresno, according to the Fresno County Sheriff’s Office.

Authorities said the man attempted to retrieve the sunglasses after they slipped into a waterless, non-flushing toilet, but instead ended up tumbling into the chemical storage tank beneath it.

Emergency crews, including Cal Fire personnel, rushed to the scene after a caller reported someone had fallen inside the confined space.

The man remained stuck for about 10 to 15 minutes before rescuers were able to pull him out.

Officials said that the language barrier became an initial hurdle during the response.

Sgt. Chris Tullus told yourcentralvalley.com, “via a Spanish translator, they advised that the subject had fallen into the chemical storage tank.”

First responders, campground staff and law enforcement worked together to extract the camper and clean him off.

There was no immediate word on whether the sunglasses that sparked the disastrous dive were ever recovered.

A sheriff’s spokesperson told The Los Angeles Times they highly suspect the eyewear was permanently “lost to the vault” and left behind in the waste chemicals.

Camp Edison’s restroom facilities, however, have previously received mixed attention online.
