>>>HOUSTON (Reuters) - An “ineffective” safeguard failed to prevent an explosive mixing of air and fuel at a Husky Energy refinery in Superior, Wisconsin, leading to a blast and fire in the plant’s gasoline-producing unit in April, a U.S. industrial safety group said on Wednesday. Air seeped through a hole in a valve within a fluidic catalytic cracking unit (FCCU), the U.S. Chemical Safety Board (CSB) said, causing an April 26 explosion that led to a massive fire and a 24-hour-long evacuation of residents living within miles of the plant. Husky, according to the CSB, had only considered a failure of the valve when locked open, not a failure when it was closed, according to an updated report the board presented of its months-long investigation at a meeting Wednesday in Superior. The failures leading to the Superior refinery explosion were similar to those that caused a 2015 explosion in an FCCU at a Torrance, California, refinery then owned by Exxon Mobil Corp. Exxon sold the refinery to PBF Energy in 2016.

rocket booster failed due to improper use of O ring as warned by NASA engineers a design flaw. A leaky closed valve is not a design flaw. A valve is not a high tech or custom designed device. My question is - is that failed valve made in china? Even US military aircraft, ships, etc have been infiltrated with Chinese made components
