Overview
When the 6.8 KG CO2 fire extinguisher was phased out of marine service, vessel operators and ship chandlers faced a straightforward but compliance-critical problem: the most common portable CO2 unit on commercial vessels no longer had a direct approved replacement available through standard procurement channels. A vessel carrying phased-out 6.8 KG units could not simply substitute a generic 7 KG CO2 extinguisher in its place — marine fire extinguishers must carry the approval of a recognised classification society or flag state authority for the vessel to remain in compliance with SOLAS fire safety equipment requirements. The replacement unit had to be type-approved for marine use, and it had to be available through an established supply chain serving the international maritime market.
The CCS 7 KG Carbon Dioxide Fire Extinguisher is the ship class approved marine replacement for the phased-out 6.8 KG CO2 unit — carrying CCS (China Classification Society) type approval, which is recognised by flag states and port state control authorities across the Asia Pacific region and internationally. At 7 KG CO2 agent charge, it meets and marginally exceeds the agent capacity of the unit it replaces, providing Class B (flammable liquids, solvents, oils, paints, thinner, and liquifiable solids) and Class C electrical fire suppression capability from a portable unit that fits the same installation positions previously occupied by the 6.8 KG unit.
CO2 as an extinguishing agent leaves zero residue on discharge — the defining characteristic that makes it the correct specification for vessel wheelhouses, navigation equipment rooms, electrical switchgear, and machinery control spaces where dry powder contamination would cause secondary equipment damage on top of the fire damage itself. The CCS 7 KG unit provides this clean-agent capability in a portable unit type-approved for marine service — the direct combination that procurement teams replacing phased-out 6.8 KG units need.
Key Features
CCS Type Approval — Recognised Marine Classification Society Certification
CCS (China Classification Society) is one of the major international ship classification societies, recognised by flag states and port state control authorities across the Asia Pacific region, China, and internationally under mutual recognition arrangements with other IACS member societies. CCS type approval for fire extinguishers means the unit has been independently tested and certified to the marine fire safety equipment standard — a requirement for portable fire extinguishers carried on SOLAS vessels. For vessel operators, technical superintendents, and ship chandlers sourcing portable CO2 extinguishers for commercial vessels, CCS approval provides the classification society certification that flag state compliance and port state control inspection requires.
Direct Replacement for Phased-Out 6.8 KG CO2 Units
The product description explicitly identifies the CCS 7 KG unit as the approved marine alternative to the phased-out 6.8 KG CO2 extinguisher — addressing a specific, documented procurement requirement in the marine supply market. Vessels previously equipped with 6.8 KG CO2 units at SOLAS-required positions need a type-approved replacement that can be substituted at those positions without triggering a fire safety equipment survey or re-approval process. The CCS 7 KG unit fills this requirement directly: it is the ship class approved replacement, available through marine supply channels, with the classification society certification that makes substitution at phased-out 6.8 KG positions straightforward from a compliance documentation perspective.
Class B and Electrical Fire Capability — Clean Agent Performance
The CCS 7 KG unit addresses Class B fires involving flammable liquids, solvents, oils, paints, thinner, and liquifiable solids — the fire classes most commonly encountered in marine machinery spaces, paint stores, and fuel handling areas. It is also effective against electrical fires, with the standard precaution that electrical supply to the affected equipment must be isolated before extinguisher discharge where safe to do so. CO2 is electrically non-conductive, making it suitable for electrical fire positions; its zero-residue discharge characteristic means no secondary contamination damage to electrical equipment in the vicinity of the fire beyond the fire damage itself — the critical performance characteristic for use in navigation equipment rooms, engine control rooms, and electrical panel spaces.
Stored-Pressure CO2 — Straightforward Operation Under Pressure
As a stored-pressure unit, the CCS 7 KG CO2 extinguisher requires no pre-actuation step beyond directing the horn at the fire and operating the valve. The cylinder contains liquid CO2 under its own vapour pressure — pointing the horn, operating the trigger mechanism, and directing the discharge at the fire base is the complete operating sequence. Under the stress conditions of a shipboard fire event — with potential smoke, noise, and other concurrent emergency response actions underway — the simplest possible operating procedure reduces the probability of incorrect operation. Crew familiarity with stored-pressure CO2 operation from portable units transfers directly to the CCS 7 KG unit without additional procedure training.
Zero Residue Discharge — No Secondary Equipment Damage
Carbon dioxide vaporises completely on discharge, leaving no residue, no contamination, and no cleanup requirement on extinguisher-wetted surfaces. In a vessel wheelhouse, navigation equipment room, or ECR where a CO2 discharge suppresses a localised fire, the affected space can be ventilated and returned to use on the basis of the fire damage alone — not the combination of fire damage and extinguisher agent contamination that a dry powder discharge in the same space would produce. For vessels where navigation and control equipment availability is a safety-of-life consideration, the zero-residue characteristic of CO2 directly affects how quickly the vessel can resume safe navigation capability after a fire event.
55B Fire Rating — Verified Class B Suppression Performance
The 55B fire rating is assigned following standardised Class B fire test conditions under the CCS marine fire extinguisher standard — verifying that the unit suppresses a Class B test fire of the specified size under controlled test conditions. A 55B rating is the standard performance benchmark for a 7 KG portable CO2 extinguisher in the marine context. For technical superintendents and HSE officers verifying that portable CO2 units meet the fire rating requirements of their vessel’s fire safety equipment specification, the documented 55B fire rating provides the performance verification data the compliance process requires — not a manufacturer’s capacity claim, but a tested and certified performance result.
255 Bar Test Pressure — High-Pressure Vessel Certification Standard
CO2 extinguisher cylinders are high-pressure vessels — the 255 Bar test pressure for the CCS 7 KG unit reflects hydraulic proof testing at well above working pressure, consistent with international pressure vessel certification standards for CO2 fire extinguisher cylinders. For vessels operating under classification society survey, high-pressure CO2 cylinder certification is a requirement separate from the fire extinguisher type approval — the cylinder must meet both the extinguisher performance standard and the applicable pressure vessel standard. CCS type approval covers both dimensions for this unit, providing a single certification framework for the complete compliance requirement.

Benefits
Compliance Continuity for Vessels Replacing Phased-Out 6.8 KG Units
The most immediate benefit of the CCS 7 KG unit for vessel operators is the ability to replace phased-out 6.8 KG CO2 extinguishers at SOLAS-required positions with a directly equivalent type-approved unit — without triggering a fire safety equipment re-survey or requiring flag state dispensation for a non-approved substitution. For ship managers working through a fleet replacement programme, or for vessels encountering phased-out unit compliance issues at port state control inspection, the CCS 7 KG unit provides a clean compliance pathway: like-for-like replacement with a current type-approved unit, documented by CCS certification, supported by part number (FEM-WI-C70) for procurement record purposes.
Navigation and Control Space Protection Without Secondary Damage Risk
For vessels where portable CO2 extinguishers are positioned in navigation equipment rooms, wheelhouses, ECRs, and electrical panel spaces, the zero-residue CO2 discharge characteristic directly protects the vessel’s operational capability in the event of a fire. Dry powder discharge in a wheelhouse or ECR suppresses the fire and simultaneously contaminates navigation and control electronics — potentially disabling systems needed to manage the vessel’s response to the fire event itself. CO2 portable units at these positions provide fire suppression without this secondary risk, maintaining navigation and control system integrity for the vessel’s ongoing safe operation after a fire incident.
Familiar Operation for Trained Marine Crew
CO2 stored-pressure portable extinguishers are among the most widely carried portable fire extinguisher types on commercial vessels — marine crew are routinely trained in their operation as part of STCW fire prevention and fire fighting competency requirements. The CCS 7 KG unit’s stored-pressure operation requires no procedure adaptation from crew familiar with portable CO2 extinguisher use: the operating sequence is identical to the 6.8 KG units it replaces, meaning no additional familiarisation training is required when the phased-out units are replaced with the 7 KG units on a vessel’s fire equipment inventory.
Asia Pacific Port State Control Compliance
CCS approval is specifically relevant for vessels trading in Asia Pacific ports — the Tokyo MOU port state control inspection regime, which covers ports in China, Japan, South Korea, Singapore, Australia, and across the Asia Pacific region, is one of the most active PSC inspection frameworks globally and regularly targets fire fighting equipment as an inspection area. CCS-approved fire extinguishers at SOLAS-required positions, with current service records and documented type approval, provide the compliance basis that Tokyo MOU PSC inspections require — reducing the risk of deficiency findings related to fire extinguisher certification at Asia Pacific port calls.
Who It’s For
Technical Superintendents Managing Fleet CO2 Extinguisher Replacement
A technical superintendent working through a fleet-wide programme to replace phased-out 6.8 KG CO2 extinguishers across multiple vessels needs a type-approved replacement unit that can be ordered in volume, shipped to ports along the fleet’s trading routes, and substituted at SOLAS-required positions without triggering individual vessel re-surveys. The CCS 7 KG unit addresses all three requirements: it is the designated approved replacement, it carries CCS type approval recognised across the fleet’s trading range, and part number FEM-WI-C70 provides a consistent procurement reference for fleet-wide ordering and inventory management.
Ship Chandlers and Marine Safety Equipment Suppliers
A ship chandler servicing vessels at Singapore, Hong Kong, or other major Asia Pacific ports regularly receives requests for CO2 portable extinguisher replacements — either as scheduled service replacements or as urgent sourcing requirements for vessels with PSC inspection findings. The CCS 7 KG unit (FEM-WI-C70) is the stocking item that addresses the most common portable CO2 replacement request in the Asia Pacific marine supply market: the approved 7 KG replacement for phased-out 6.8 KG units, with CCS certification, available for immediate supply from Singapore stock.
Vessel Masters and Chief Officers Responsible for Fire Safety Equipment
A chief officer conducting the vessel’s routine fire safety equipment inspection identifies a phased-out 6.8 KG CO2 extinguisher that needs replacement before the next port state control inspection. The replacement needs to be type-approved, correctly specified for the fire class and position requirements at that location, and available through the vessel’s supply chain before the next scheduled port call. The CCS 7 KG unit is the unit the chief officer needs to specify in the ship’s stores requisition — confirmed type-approved, correct agent type and capacity, and available through marine supply channels in Asia Pacific ports.
Possible Applications
Vessel Wheelhouse and Navigation Equipment Rooms
Wheelhouses and navigation equipment rooms contain electronic chart systems, GMDSS communication equipment, radar installations, and AIS transponders — all sensitive to powder contamination. CO2 portable units at these positions provide fire suppression for electrical and Class B fire events without the secondary contamination risk of dry powder discharge. The CCS 7 KG unit’s marine type approval makes it the correct specification for these positions on SOLAS vessels.
Engine Control Rooms and Machinery Control Spaces
ECRs and machinery control spaces house vessel management systems, engine monitoring electronics, and electrical distribution equipment that cannot tolerate dry powder contamination. Portable CO2 extinguishers at ECR positions provide first-response capability for electrical and Class B fire events in these spaces — the CCS 7 KG unit providing 9+ seconds of CO2 discharge at the SOLAS-required positions in machinery control areas on commercial vessels.
Electrical Switchgear Rooms and Panel Spaces
Main switchboard rooms and electrical distribution panel spaces are standard positions for portable CO2 extinguisher provision under SOLAS Chapter II-2. The CCS 7 KG unit meets the type approval requirement for these positions, provides Class B and electrical fire suppression, and leaves no residue that would contaminate switchgear contacts or bus bar insulation beyond any fire damage from the event itself.
Vessel Paint Stores and Flammable Liquid Storage
Paint stores, solvent stores, and flammable liquid storage rooms on commercial vessels carry Class B fire risk from paints, thinners, and solvents — specifically listed in the product description as fire classes addressed by this unit. Portable CO2 extinguishers at paint store access points provide first-response Class B suppression in enclosed storage spaces where the fire load is flammable liquid.
Accommodation Block Corridors and Public Spaces
SOLAS fire fighting equipment provisions require portable fire extinguishers at defined intervals in vessel accommodation blocks, on passenger vessel public decks, and at crew accommodation corridor positions. CCS-approved portable extinguishers meet the type approval requirement for these positions — the CCS 7 KG unit is suitable for corridor and accommodation positions where Class B fire risk from cabin contents, galley fuel, and electrical fittings is the primary fire scenario.
Offshore Supply Vessels and Platform Support Vessels
OSVs and PSVs operating in the Asia Pacific offshore sector are subject to SOLAS and flag state fire safety equipment requirements and operate within the Tokyo MOU PSC inspection zone. CCS-approved portable CO2 extinguishers at SOLAS-required positions on these vessels provide the type approval certification that Tokyo MOU PSC inspection requires — relevant for the large fleet of OSVs and PSVs operating out of Singapore, Batam, and other Asia Pacific offshore support bases.
Coastal Trading Vessels and River/Port Craft Under National Regulation
Smaller commercial vessels operating in coastal and inland waterways under national maritime authority regulation in China and across CCS-recognised jurisdictions may require CCS-approved fire fighting equipment under their applicable flag state rules. The CCS 7 KG CO2 unit (FEM-WI-C70) provides a type-approved portable CO2 specification for these vessels alongside the international commercial fleet market.
Trust & Certifications
CCS Type Approval — China Classification Society Marine Certification
CCS (China Classification Society) is a full member of the International Association of Classification Societies (IACS) and one of the largest ship classification organisations in the world, classifying a significant proportion of the global commercial vessel fleet. CCS type approval for marine fire safety equipment is recognised by flag states and port state control authorities operating under Tokyo MOU, Paris MOU, and other regional PSC frameworks. For portable fire extinguishers on SOLAS vessels, CCS type approval provides the classification society certification that flag state compliance requires — equivalent in regulatory standing to type approvals from other major IACS member societies including Lloyd’s Register, DNV, Bureau Veritas, and ABS.
55B Fire Rating — CCS Standard Class B Performance Verification
The 55B fire rating is the Class B fire suppression performance benchmark achieved by the CCS 7 KG unit under standardised CCS fire test conditions — verifying the unit’s suppression capability against a defined test fire size rather than relying on agent capacity alone as a performance proxy. For technical superintendents and HSE officers verifying fire equipment compliance against vessel fire safety management system specifications, a documented fire rating under a recognised classification society standard provides the performance evidence basis that the verification process requires.
Approved Replacement for Phased-Out 6.8 KG Units — Documented Compliance Pathway
The CCS 7 KG unit’s status as the ship class approved marine alternative to the phased-out 6.8 KG CO2 extinguisher is the product’s most significant compliance credential for the marine market. This is not a general-purpose CO2 extinguisher adapted for marine use — it is the specifically approved replacement unit for the most common portable CO2 extinguisher previously carried on commercial vessels, providing a documented, recognised compliance pathway for vessel operators managing the transition from the phased-out 6.8 KG specification.
SOLAS Chapter II-2 Compliance Support
SOLAS Chapter II-2 requires portable fire extinguishers on commercial vessels to be of an approved type, maintained in serviceable condition, and positioned at required locations throughout the vessel. CCS type approval satisfies the “approved type” requirement of SOLAS Chapter II-2 for vessels whose flag state recognises CCS as an approved classification society — which covers the majority of vessels operating in the Asia Pacific region and internationally. Port state control inspections under Tokyo MOU routinely verify fire extinguisher type approval certification; CCS-approved units with current service records provide the compliance documentation basis that PSC inspectors require.
