I think the fact is where you made mention of implement procedures to ensure only authentized personnel can enter in the lab, i the company should also consider posting caution signs to alert individuals of the sensitive nature of the lab this could also be of help too, pulses always ensure throughful screening of staff and visitors before gaining access to the lab. Prioritizing lan security services that can protect sensitive information assets and personal data of clients
There is no lab that does not have caution signs before entrance, at the entrance, there must be some caution signs out there for anyone entering to see for themselves before they proceed with their movement, as to be extra cautious, so they would be aware of the nature of activities going on there. This caution sign awareness cuts across all fields of operation as it is the normal global standard and also amongst the safety rules and principles. Regardless of the mode of operation, the lab must have a caution sign.
However, at some organisations, before entrance into the premises, staff and visitors are properly screened before gaining entrance, and I believe this to be the standard of this organisation. Organisations that deal with sensitive information mostly do screening before entrance, because anybody can come in with anything just to get clues on what is going on at the lab, for facts or whatsoever as it pleases them.
