Explosion at Hot Tub Manufacturing Plant


Hot Spring Spas Resin Vats Explode!



An explosion took place at Watkins Manufacturing home for the brands Hot Spring Spas, Caldera Spas, and  Freeflow Spas.  No injuries were reported. The explosion was on the exterior of the plant but the container that exploded did puncture the roof and cause the sprinkler system to break, causing flooding.

Watkins is known for known for being a very responsible company and most would speculate this was from isolated human error, and not poor processes on the part of the company.


VISTA, CA. — An 8,000-gallon container of chemicals exploded and launched through the roof at a hot-tub factory in south Vista late Thursday night, fire officials said.

No one was injured. A security guard was the only person around at 10:30 p.m. when the container exploded outside the main building of Watkins Manufacturing Corp., Vista Fire Department Capt. Robert Ford said Friday.

Hazardous materials crews from San Diego, the county, and Camp Pendleton were called in about 11 p.m. With company officials they spent the next nearly five hours dealing with the mess, Ford said. He said the cause of the blast was still under investigation.

The company makes Hot Spring and Caldera spas and hot tubs at an industrial park on Park Center Drive, west of Business Park Drive.

The container, 10 feet tall and 8 feet in diameter, held a resin-type of chemical and stood with similar containers on a raised platform behind a wall and beneath a metal roof adjacent to the factory building, Ford said.

The flying container dropped through the factory roof and ruptured the sprinkler system. When water from the sprinklers mixed with the chemical, it created a kind of slurry that did not spread beyond the immediate area or get into any waterways, Ford said.

He said when firefighters got to the factory, they could see light smoke, running water, and debris. There was no fire.

Firefighters called for additional engines and the hazardous materials crews. Ford said further clean-up duties were handed over to company officials early Friday.

Manufacturing any product can be hazardous,
And if we learn from the history of our industry,
We can avoid repeating the same mistakes.
