no humans allowed
A policy prohibiting all people from entering a defined structure or area, including places closed for safety or conservation.
A restriction on human entry indicates that no persons are allowed within a structure or an area. This policy may be implemented for safety reasons, such as in places used for radioactive and hazardous material storage; or it may be applied for protection of nature, in order to let animals and plants grow without interference or threats from human beings.
The exclusion applies to human entry as such. Its purpose can concern hazardous conditions or protection of plants and animals.
Employees only still permits a specified group of people to enter. A no-human-entry restriction does not contain that ordinary staff allowance.
