Oh, I know OC, and I know it’s good for automation and monitoring. I’m just saying that GT can also consider adding these content, so it looks like a high-tech factory, and it’s easier to manage.
In addition, some suggestions on warning signs are as follows:

Warning: It’s a common attention sign that can be used in many places.

Fire hazard: Can be placed in fire prone situations, such as near the burning box or inflammable warehouse.

Electrical hazard: Can be placed near uninsulated wires to prevent electric shock.

Ionizing radiation: Maybe it can be placed near a nuclear reactor…
Explosive hazard: It can be used in situations where explosion may occur (e.g. boilers)

Surface hot: DO NOT TOUCH THE STEAM PIPE!

Toxic hazard: Maybe it could be decorated more like a chemical plant…

Corrosion hazard: It may remind you that you should use anti-corrosive drums…

Laser caution: Maybe the LU in the air will be added later to prevent injuries…
Magnetic hazard: Maybe it’s just a decoration that fits near the electromagnet…
Cryogenic hazard: Maybe this should be placed near cryotheum pipes…
These signs can be made in a form similar to a cover, but can be placed on any blocks to decorate your factory,Maybe some fictional dangers, such as magical danger in GT5U,by using a pentagram, may need to design some warning signs, such as flux taint warning signs.These signs are not good at drawing on the texture of 16x16 px. Maybe they should be added to 32x32 or 64x64 px… and maybe yellow and black striped blocks should also be added…
