Marine Fire Blankets: Compliance, Types, and Maintenance
In the high-stakes environment of a vessel at sea, where evacuation is not an immediate option and professional fire services are miles away, the initial response to a fire is critical. While fire extinguishers are the most recognized first line of defense, a more specialized and equally vital tool is the marine fire blanket. This simple yet profoundly effective device can mean the difference between a contained incident and a catastrophic emergency.
This guide delves into everything you need to know about marine fire blankets, ensuring your vessel is equipped, compliant, and prepared.
What is a Fire Blanket and How Does It Work?
A fire blanket is a safety device designed to extinguish small incipient fires. It consists of a sheet of fire-retardant material (typically fiberglass or Kevlar) stored in a quick-release container for easy access.
The science behind it is simple: it smothers the fire. Fire requires oxygen to sustain combustion. By placing the blanket over a fire, it creates a seal that cuts off the oxygen supply, effectively starving the fire. This method is particularly effective for:
Class F Fires: Cooking oils and fats (e.g., a galley fire).
Class A Fires: Common combustibles like wood, paper, or textiles (e.g., a trash bin fire).
Enveloping a Person: If a crew member’s clothing catches fire, a fire blanket can be wrapped around them to smother the flames quickly and safely.
Are There Different Types of Marine Fire Blankets?
Yes, not all fire blankets are created equal, especially in the demanding marine environment. The key types are distinguished by their material and construction:
Fiberglass Fire Blankets: The most common and cost-effective type. They are made from woven fiberglass fabric and are effective for most standard applications. They are resistant to high temperatures and corrosion.
Kevlar® Fire Blankets: A premium option known for its exceptional strength, durability, and higher heat resistance. Kevlar blankets are less prone to tearing and can withstand more abrasive conditions, making them ideal for harsh marine use.
Silicone-Coated Fire Blankets: These blankets have a fiberglass base coated with silicone rubber. This coating provides superior water and chemical resistance, prevents the blanket from sticking to hot surfaces, and makes it easier to clean and reuse after deployment.
For marine use, silicone-coated or Kevlar-based blankets are often recommended due to their enhanced durability and resistance to saltwater corrosion and humidity.
SOLAS and IMO Regulations: Why Compliance is Non-Negotiable
The International Maritime Organization (IMO) and the Safety of Life at Sea (SOLAS) convention have strict regulations governing fire safety equipment on vessels. Compliance is not a suggestion—it is a legal requirement for operating a commercial vessel.
Key regulations and codes relevant to fire blankets include:
SOLAS Chapter II-2: This chapter details construction and equipment requirements for fire safety. It mandates that all vessels must be equipped with appropriate fire-fighting appliances.
The International Code for Fire Safety Systems (FSS Code): Chapter 10 of the FSS Code specifically addresses the requirements for fire-fighting equipment, including portable extinguishers and, by extension, blankets. It stipulates that equipment must be approved by the Administration (e.g., the flag state) based on testing standards set by the IMO.
Manufacturing Standards: Marine fire blankets must be manufactured and tested to rigorous international standards to be certified. The most recognized standard is MED (Marine Equipment Directive) 96/98/EC, which ensures the product meets the strict safety and quality requirements for use on ships. Look for the MED wheelmark on the blanket and its container as proof of certification.
Using non-certified equipment is a severe safety risk and can lead to detention of the vessel by Port State Control during an inspection.
Proper Placement and Usage: A Step-by-Step Guide
For a fire blanket to be effective, it must be accessible and crew must be trained to use it correctly.
Placement:
Galleys: Mounted near the stove or fryer, but not so close that it becomes inaccessible in a fire.
Engine Rooms: Located near exits or at key workstations.
Messes and Common Areas: Easily accessible wall mounts.
Workshops: Near areas with electrical equipment or flammable materials.
How to Use a Fire Blanket:
Pull: Quickly pull the tabs to release the blanket from its container.
Shield: Hold the blanket by the fabric tabs, allowing it to unroll. Use it to shield your hands and arms from the heat.
Cover: Gently place—do not throw—the blanket over the base of the fire.
Turn Off: If it is a cooking fire, turn off the heat source immediately.
Leave: Leave the blanket in place for at least 15-30 minutes or until the heat source has completely cooled down to prevent re-ignition.
Evacuate: If the fire does not go out immediately, evacuate the area, sound the alarm, and follow your vessel’s emergency procedures.
Maintenance and Inspection: Ensuring Readiness
A fire blanket is only useful if it is in perfect condition. Regular inspection is crucial and should be part of the vessel’s planned maintenance system (PMS).
Visual Inspection: Monthly checks for any signs of damage, such as tears, holes, or discoloration.
Container Inspection: Ensure the container is not corroded, the blanket is easy to remove, and the instructions on the case are legible.
Certification Check: Ensure the blanket’s certification tag is present and valid. After use, a fire blanket must be professionally inspected and re-certified or replaced.
Never attempt to refold a used blanket yourself. Specialized techniques are required to ensure it will deploy correctly next time.
Frequently Asked Questions (FAQ)
Q1: Can a fire blanket be reused?
A: It depends. If it was deployed on a small fire and shows no damage (no burns, stains, or tears), it may be reusable after a professional inspection and repacking. However, if there is any damage or it was used on a chemical/oil fire, it must be replaced. Always err on the side of caution and consult the manufacturer’s guidelines.
Q2: How often should a marine fire blanket be replaced?
A: Even if never used, fire blankets have a service life. The manufacturer’s instructions will specify this, but it is typically between 5 to 7 years. The container and blanket should be replaced if any signs of degradation appear or after the stated service life expires.
Q3: Are fire blankets effective on electrical fires?
A: Yes, but with caution. A fire blanket is non-conductive, so it can be used to smother a small electrical fire (Class C). However, the first action should always be to de-energize the equipment if it is safe to do so. Never use water on an electrical fire.
Q4: What size fire blanket do I need for my galley?
A: Standard sizes are 1m x 1m or 1.2m x 1.2m. The larger size is generally recommended as it provides better coverage for larger pots and pans. The blanket must be large enough to completely cover the potential fire source.
Q5: Where can I get my fire blankets serviced and certified?
A: This is a specialized task that must be performed by an accredited service provider. Companies like Ftron Technology offer comprehensive servicing, ensuring your blankets are inspected, repacked, and certified according to strict marine regulations.
