Security Level 2 Sign

Security Level 2 Sign for ISPS Heightened Security Operations

A security level 2 sign is used aboard vessels and at port facilities to support operations under ISPS Security Level 2, the heightened security state declared when there is an increased risk of a security incident, even though no specific target or timing has been identified. This sign forms part of the broader signage package that helps crew and port personnel recognise and respond correctly when a facility or vessel moves from routine operations into a period of additional protective measures.

Referenced under IMPA 33.2702 and ISSA 47.527.02, this sign is used to communicate the operational security posture at a vessel or facility during the period a heightened level applies. Because Security Level 2 involves additional protective measures beyond normal baseline procedures, such as increased monitoring, restricted access and more frequent checks, having clear signage in place supports consistent understanding among crew, contractors and visitors during that period.

Supplied in a 150x300mm format, the security level 2 sign is sized for posting at gangways, access points and security offices, consistent with where other ISPS-related signage is typically displayed on a vessel or at a facility.

What Security Level 2 Means in Practice

Under the ISPS Code, security levels describe the degree of risk that a security incident may occur, and the level in force determines what additional measures a ship or port facility must apply. Security Level 1 is the baseline, with minimum protective security measures maintained at all times. Security Level 2 applies for a defined period when there is a heightened risk of a security incident, requiring additional protective measures such as tighter access control, more frequent screening and closer coordination with port facility security officers. Security Level 2 applies only for a limited period when a security incident is probable or imminent, calling for further specific protective measures.

A security level 2 sign supports a vessel’s or facility’s Ship or Port Facility Security Plan by giving crew and visitors a consistent reference point during a declared heightened period, reinforcing the additional procedures already communicated through security briefings and access control measures.

Mounting Format Options

This security level 2 sign is available as a self-adhesive label for a flat gangway or security office surface, or as a rigid panel for mounting on a stanchion or barrier frame at an exterior access point. Facilities and vessels that update signage between security levels often keep a rigid panel mounting bracket in place year-round, allowing the specific notice to be changed quickly as the declared level changes.

Material, Format and Standards Context

This sign is produced on standard, non-luminous marine-grade vinyl, suited to exterior gangway, access point and security office locations where it needs to withstand weather and regular handling without requiring the photoluminescent properties used on lifesaving appliance signage. The 150x300mm size fits typical mounting points alongside other access control and security notices.

Vinyl is available in Class C or Class D grade to match a vessel’s existing signage specification. Standardised security and safety signage of this type is developed around the same graphical symbol conventions addressed by ISO 24409, supporting consistent recognition across international shipping and port operations. For the full range of ISPS Code signage, including access control and security level signage, see our ISPA Signs category. Keeping a security level 2 sign in place alongside related access control notices supports the documentation trail a port state control officer expects to see when reviewing a vessel’s security records during a call.
