What is the main finding of this research?

Multiple human body explosion accidents have occurred due to high-concentration hydrogen inhalers, with 'normalization of deviance' as a background factor. A shift to low-concentration hydrogen inhalation is a fundamental solution for intrinsically safe design.

What is 'normalization of deviance' in concrete terms?

It is an organizational phenomenon where a dangerous condition is considered 'normal' because 'it was fine before'.

What should I do for safe hydrogen inhalation?

Use a low-concentration hydrogen inhaler that keeps the device output concentration at or below the empirically verified value of 10% by volume.
