The framework regulations § 60

§ 60 Marking of safety zones

Established safety zones shall only be marked if the operator or the Ministry of Labour and Social Inclusion deems it necessary. Any marking shall be in accordance with international marking rules.
The Ministry of Labour and Social Inclusion can require markings to be altered.

According to the first subsection, safety zones are typically not marked. This is because these zones should be known upon their establishment, and the safety-related value of marking is therefore small. Furthermore, the marking buoys can come loose, and can thus amount to a risk for facilities and vessels. However, the operator can, following a comprehensive assessment, mark safety zones.
