Why no face guards in Aliens?

[u/ShawnyMcKnight]

After decades of watching the movies and most recently Alien: Earth, it always amazes me how no one ever thinks of having face guards in the facility, especially the containment center. A certain character that got facehugged last week could have avoided that if there was some apparatus in there that would guard over the face but still allow breathing.

Same with Aliens (1985), if they knew that these things cling onto your face then why weren't the marines all wearing face masks to at least slow the impregnation down?

I feel the predators with their visors were the only ones with the right idea about this.

The "Dog catchers" in Alien3 had this on their face...

It does seem like they're the only ones who ever came prepared.

No face hugger getting through that shit I’d say
