ISO 7010 No Access Symbol Update
ISO 7010 Symbol Update for No Access for Unauthorized Persons
One of the measures of the effectiveness of a safety label is its ability to communicate a critical message in a fraction of a second. This is particularly true in high risk industrial environments where unauthorized entry can lead to severe injury or equipment damage. To ensure these messages are as clear as possible, the International Organization for Standardization, known as ISO, maintains a rigorous schedule of review and refinement for graphical symbols. The recent ISO 7010 symbol update for No Access for Unauthorized Persons is a direct result of this ongoing commitment to human factors research and global safety alignment.
At Clarion Safety, we recognize that our customers rely on us to stay informed about these technical shifts, in line with today’s safety communication best practices. The update involves ISO symbol P080, a common prohibition symbol used across countless industries. In the prior design, the red prohibition slash was positioned below the human figure. While this was the industry standard for years, recent comprehension testing conducted by ISO experts revealed a more effective layout. The new ISO 7010 registered design now places the red prohibition slash directly over the large human figure. By overlapping these two elements, the symbol more clearly indicates that the person is the subject of the prohibition. This change reduces the time it takes for a viewer to process the instruction, which is a vital factor in preventing accidents.
