I remember seeing this movie in television a long time ago. So long that some parts that I remember might be a bit wrong.
The basic premise is that scientists accidentally or intentionally release a poison gas inside an underground research facility in what looked like the Arizona desert. The poison makes everyone who gets infected in to deranged psychopaths. They're still capable of talking and doing normal tasks and working in a group, but they can't stand light, so they break most of the brighter lights in the facility. The government wastes no time sealing all the entrances and they send a team of soldiers down in to the facility. But they get ambushed and killed by the laboratory personnel. As far as I remember the main character's daughter is stuck inside the facility and the main character (man) enters the facility with a partner through a ventilation shaft. That's basically everything I can remember, it looked like it was filmed in the 80's or early 90's tops. I'm also pretty sure it was a TV movie.
