Surface Ship HAZMAT Website

The Surface Ship HAZMAT Website is a MyNAVSUP portal application (hosted at mynavsup.nag.navy.mil) supporting hazardous-material (HAZMAT) control and management aboard Navy surface ships. It is operated by NAVSUP Weapon Systems Support's afloat HAZMAT program and requires DoD PKI (CAC) authentication to reach.

What it is

A shipboard HAZMAT-management resource within the MyNAVSUP portal ecosystem, part of the same family of afloat HAZMAT IT tools NAVSUP WSS maintains for the fleet. NAVSUP's published afloat HAZMAT toolset includes the Hazardous Inventory Control System (HICS) for CHRIMP operations aboard surface ships, the Ship's Hazardous Material List (SHML) that controls afloat requisitioning via Special Material Content Code assignment, and DLA's Hazardous Materials Information Resource System (HMIRS) for Safety Data Sheets.

Who operates it

NAVSUP Weapon Systems Support (NAVSUP WSS) owns and maintains the afloat HAZMAT program, including its N261 Afloat HAZMAT and Pollution Prevention Division (part of the broader N26 Hazardous Material and Pollution Prevention Department). NAVSUP is designated the Navy's lead organization with technical and management authority for the Hazardous Material Control and Management (HMC&M) and Pollution Prevention Programs, of which shipboard HAZMAT management is a part.

Access

The site loads only behind DoD PKI (CAC) client-certificate authentication — attempting to reach it without a CAC returns a certificate-chain error rather than public content. The Directus record's stored access type of "public" does not match this behavior; it should be treated as CAC-gated (cac_required). No separate SAAR account-request process for this specific URL is publicly documented; access appears to follow standard MyNAVSUP/CAC provisioning used across NAVSUP's afloat HAZMAT tool family.

How logisticians use it

Surface-ship supply and HAZMAT personnel (CHRIMP technicians, HAZMAT Minimization Center staff, and ship's supply departments) use tools in this family to manage the shipboard HAZMAT inventory lifecycle — tracking authorized materials, requisitioning against the Ship's Hazardous Material List, checking Safety Data Sheets, and supporting proper identification, storage, and turn-in of hazardous material under the Navy's CHRIMP program.

Related systems

Part of the same NAVSUP WSS afloat HAZMAT toolset as the Hazardous Inventory Control System (HICS), the Ship's Hazardous Material List (SHML), and the Hazardous Material Management (HMM) Tool; also connects conceptually to DLA's Hazardous Materials Information Resource System (HMIRS) for Safety Data Sheets and to the Navy's CHRIMP/HMC&M program more broadly.
