Self-Contained Breathing Apparatus (SCBA): Statutory Marine Safety Inspection, Testing & Annual Survey
Self-Contained Breathing Apparatus (SCBA) sets are primary life-support appliances used by marine firefighting squads. Governed by SOLAS Chapter II-2 Reg. 10.10 and FSS Code Chapter 3, every commercial cargo ship must carry a minimum of two (2) firefighter outfits, each equipped with an approved positive-pressure SCBA. The installation requires 200 bar or 300 bar cylinders containing at least 1,200 liters of free breathing air (minimum 30 minutes operational duration at 40 L/min consumption). Annual IACS testing includes pneumatic high-pressure leak testing, demand valve positive pressure verification, audible low-pressure warning whistle activation (55 ± 5 bar), face mask speech diaphragm checks, and 5-year hydrostatic testing.
Self Contained Breathing Apparatus (SCBA) – Comprehensive Safety Solution by Seanav Marine
At Seanav Marine, we recognize that safety is the cornerstone of all marine, industrial, and emergency response operations. Among the most critical safety equipment for hazardous environments is the Self Contained Breathing Apparatus (SCBA). Our experienced team, backed by decades of domain expertise and supported by a strong global network of channel partners, provides world-class SCBA solutions to clients worldwide.
SCBA units are vital for protecting personnel working in oxygen-deficient, smoke-laden, toxic, or otherwise hazardous environments. They provide clean, breathable air from a self-contained high-pressure cylinder, allowing the user to work safely in areas where the ambient air is unsafe or immediately dangerous to life and health (IDLH).
What is a Self Contained Breathing Apparatus (SCBA)?
A Self Contained Breathing Apparatus is a wearable respiratory protection device that delivers breathable air to the wearer independently of the surrounding atmosphere. SCBA systems are commonly used in firefighting, confined space entry, chemical handling, marine emergencies, rescue operations, and industrial hazardous environments.
An SCBA set typically includes:
High-Pressure Cylinder – Stores compressed breathing air (usually at 200–300 bar).
Full-Face Mask (Facepiece) – Provides a sealed fit and supplies clean air to the user while protecting eyes and face from smoke, gases, or chemical splashes.
Demand Valve and Pressure Regulator – Controls air flow from the cylinder to the face mask, ensuring constant breathable air at safe pressure.
Harness and Backplate Assembly – Allows the SCBA to be worn on the back comfortably and securely during operations.
Pressure Gauge and Warning Whistle – Displays remaining air pressure and sounds an audible alarm when air is low.
PASS Device (Personal Alert Safety System) – Alerts rescuers if the user becomes motionless, signaling possible distress.
Types of SCBA
SCBA systems are categorized based on how they supply air and how long they can support the wearer:
1. Open-Circuit SCBA
Most commonly used type
Compressed breathable air from the cylinder is inhaled by the user, and exhaled air is released into the atmosphere.
Used extensively in firefighting, shipboard emergencies, and industrial rescue.
2. Closed-Circuit SCBA (Rebreather Type)
Exhaled air is scrubbed of carbon dioxide and enriched with oxygen from a cylinder, then recirculated.
Offers longer-duration use (up to 4 hours).
Common in mine rescue, tunnel maintenance, and specialized confined space applications.

Regulatory Compliance and Standards
Safety regulations for SCBA are governed by international maritime and industrial safety codes. SCBA units offered by Seanav Marine comply with:
International Maritime Organization (IMO) SOLAS (International Convention for the Safety of Life at Sea) Chapter II-2, Regulation 10.10.1 – requiring the carriage of at least two SCBAs on board all ships, and additional sets for fire parties.
EN 137 – Standard for compressed air breathing apparatus used by firefighters.
MED (Marine Equipment Directive) – Required certification for SCBA used on EU-flagged vessels.
NFPA 1981 – Standard on open-circuit SCBA for emergency services (common for firefighting units).
Occupational Safety and Health Administration (OSHA) and National Institute for Occupational Safety and Health (NIOSH) guidelines for industrial usage.
All SCBA systems are also subject to hydrostatic testing, annual servicing, and regular functional checks as per the manufacturer’s and international safety requirements.

Frequently Asked Questions (Statutory & Technical FAQ)
How many spare cylinders are required for shipboard SCBA sets?
Under SOLAS Chapter II-2 Reg. 10.10.2.5, vessels must carry two (2) spare cylinders for each required SCBA set. However, if the ship is equipped with a certified breathing air compressor capable of refilling empty cylinders to 300 bar, only one spare cylinder per set is required.
What is the statutory hydrostatic test interval for SCBA carbon-composite cylinders?
Composite cylinders must undergo hydrostatic pressure testing at 450 bar every 5 years by an authorized facility and have a maximum statutory service life of 15 to 30 years.
What pressure should trigger the SCBA low-pressure warning whistle?
The pneumatic warning whistle must activate automatically when cylinder pressure drops to 55 bar (± 5 bar), sounding continuously at ≥ 90 dB(A) until the cylinder is exhausted.
