When you read some instructions and then report them to another person, use the phrase "It says to ___." For example:
It says to add the onions and celery and simmer for five minutes.
For warnings, say "It says not to ___":
It says not to touch the connectors.
You can also specify where the instructions came from:
The sign says not to go in there.
It might seem strange to use "says" with written instructions since the instructions don't actually speak. But English doesn't have a separate verb to describe information that's written down, so we use "says".
"Ventiation" means allowing air to move between the indoors and outdoors. This can be done with windows, vents, or fans.
Chemicals which are dangerous for people to breathe often have a warning. The warning says that you should use the chemical in a "well-ventilated area", so that the person using it can get fresh air.
