How many industries offer a hazard pay? I know the military does for conflict zones, what amount do they offer?

May also be coming to doctors, nurses (if it isn't there already):

Customs workers, corrections officers, and a ton of other jobs also negotiating it. In Philly, among them are police, firefighters, sanitation workers, health care workers.

As for "who typically offers this" I would argue that this isn't quite like a "normal" time. Many people are putting their health on the line to come to work which is not something that is normally part of the decisionmaking process for their regular wage. As a result of that increased risk and because of the huge demand for their labor a large increase in pay makes a lot of sense (even if we take the "combat pay" stuff out of the equation. Demand-alone would increase their wages)
