Helium leaks are hard to detect. Helium is odorless, colorless, tasteless, and does not react with other chemical substances. Not only can we not see or smell it, but traditional gas sensors have trouble detecting the element because they rely on chemical reactions. Despite this, identifying a helium leak is still crucial, because excess helium can displace oxygen in a confined space, leaving less oxygen for people to breathe.
