In the "reducing agent" article in Wikipedia it says

Good reducing agents are reagents that deliver $\ce{H2}$.

Wouldn't that make water unsafe to dissolve oxidizing agents?

    $\begingroup$ I don't quite see how the statement about reducing agents is related to the safety of dissolving oxidising agents in water. Perhaps you could clarify this. $\endgroup$ – bon Jun 15 '15 at 16:40
  • $\begingroup$ @bon I think OP means that water may deliver $\ce{H2}$ and is as such unsafe to dissolve oxidizers in. $\endgroup$ – tschoppi Jun 15 '15 at 16:50

If the oxidizing agent is sufficiently strong, e.g. fluorine, yes. "[W]ater spontaneously combust[s] under a fluorine jet."

However, there are only a few oxidizers, such as fluorine, fluorine trichloride and dioxygen difluoride that can displace oxygen from water. More likely you'd encounter a strong reducing agent, such as Group I metals, that would attach to the oxygen in water, liberating hydrogen.

The safety arises from the solution's characteristics. Some oxidizers produce highly alkali solutions which pose personnel risks from chemical burns. This nature occurs to a lesser extent when dry chemical contacts the skin or mucus membranes ext. as the agent acquires water from the body and in essence forms saturated solutions at the contact sites.
