Emergency Escape route :Keep it clear and clean

Just thought of writing this post after my return from an audit.
We must always ensure that the emergency escape routes/staircases are free of obstructions.Kindly ensure that you do not store any materials in this path,as it would proove detrimental in case of real emergency.
The route/path must be free,so that people can easily run out and evacuate as early as possible.
I think below are the few measures you can take to ensure this:

• Include checking the emergency escape route/path as a check-point in your Housekeeping cheklist and let this be checked atleast once after the end of the shift(No problem,if your housekeeping persons wants to check this every hour/frequently)
• Educate all employees on the importance of following this very important rule
• Display good visual controls,to inform all that it is not a good practice to block emergency escape routes
