People get fired over accidents
Why are they using poison to clean a machine like that anyways? It doesn’t add up

It is very likely not harmful if the machine is properly rinsed and the right amount of cleanser is used. Toxicity often depends on the amount of the substance involved. Even substances that are benign in smaller amounts can be toxic at larger doses.
