Boiler water treatment

I wish to know, is it alright to use hydrazine in low pressure boilers for oxygen scavenging. Literature suggests the use of Sodium Sulphite at low pressure. what happens if hydrazine is used instead of Sodium Sulphite ?

Hydrazine is a powerful reducing agent and oxygen scavenger, so it will probably do the same thing as the sodium sulphite. But it's SUCH a powerful reducing agent that it is explosive. I'm not confident from this distance that you can use it safely.
