From the linked article:

The 2022 injury rate at the company’s manufacturing-and-launch facility near Brownsville, Texas, was 4.8 injuries or illnesses per 100 workers – six times higher than the space-industry average of 0.8.

No mention of other industries, but a quick search shows that the injury rate is 2.4 in construction and 3.2 in manufacturing. However, it’s important to note that all industries underreport injuries, especially SpaceX, as OP’s article discusses.

Also, I think it’s interesting to note that Texas, where SpaceX are moving most of their operations, has the most worker deaths of any state.
