My husband has a rash under his arms and it is only getting worse can anyone help? - rash under arms

My husband works for a company manufacturing steel tanks together in the warm Florida SUN This outburst came a few weeks ago, and thought to irritate his armpit hair, he shaved almost everything. The rash is still angry that he said he had no itching or burning, but it can get worse. Suggestions?
