Scott Sigma 2 Self Contained Breathing Apparatus (SCBA) – 6.8L / 300 Bar
Per piece
The Scott Sigma 2 Self Contained Breathing Apparatus (SCBA) is a professional respiratory protection system designed to provide an independent supply of breathable compressed air in hazardous, smoke-filled, contaminated, or oxygen-deficient environments.
Developed for demanding professional applications, the Sigma 2 combines a 6.8-litre / 300 Bar high-pressure cylinder, full-face mask, breathing system, and ergonomic carrying harness in a compact configuration. It is suitable for trained personnel involved in firefighting, rescue, industrial safety, confined-space operations, and emergency response.
The ergonomic harness and back plate are designed to support secure equipment positioning and user mobility, while the full-face mask provides respiratory and facial coverage with a wide field of vision.
Independent Breathing Air Supply: Provides compressed breathing air independently of the surrounding atmosphere.
6.8L / 300 Bar Cylinder: High-pressure cylinder provides a dedicated breathing-air supply for professional emergency and industrial applications.
Full-Face Respiratory Protection: Full-face mask provides respiratory and facial coverage during operation.
Wide Field of Vision: Panoramic visor helps maintain visibility and situational awareness in demanding environments.
Low Breathing Resistance: Breathing system is designed to support comfortable airflow during physically demanding operations.
Ergonomic Carrying System: Adjustable harness and back plate help distribute equipment weight and provide a secure fit.
Pressure Monitoring: Allows the user to monitor the available breathing-air supply during operation.
Professional-Grade Construction: Designed for use in firefighting, rescue, industrial safety, and emergency-response environments.
Communication Compatibility: Can support compatible communication accessories depending on the mask and system configuration.

Specifications may vary depending on the exact cylinder, facepiece, and SCBA configuration supplied. Verify the manufacturer's specifications before purchase.
The stated 45-minute duration is a nominal rating and should not be considered a guaranteed working time. Actual usable duration can vary significantly depending on:
User breathing rate
Physical workload
Cylinder filling pressure
Environmental conditions
Equipment configuration
Reserve-air requirements
Users should follow established operational procedures for air management and safe withdrawal from hazardous environments.

The applicable standards, approvals, cylinder testing requirements, and certifications depend on the exact Sigma 2 configuration, cylinder, facepiece, and market in which the equipment is supplied.
Where specified, configurations may be designed to meet applicable EN 137 requirements for self-contained open-circuit compressed-air breathing apparatus.
Always verify current certification, cylinder test documentation, product identification, and applicable regulatory requirements before purchase or deployment.
The Scott Sigma 2 SCBA provides a practical respiratory protection solution for trained professionals operating where ambient air cannot be safely relied upon.
Its combination of a high-pressure breathing-air cylinder, full-face mask, ergonomic carrying system, pressure monitoring, and professional-grade breathing components makes it suitable for firefighting, rescue, industrial safety, and specialized emergency-response applications.
SCBA is life-safety equipment and must only be used by appropriately trained and authorized personnel. Users should be trained in equipment inspection, donning, facepiece fit checking, air management, emergency procedures, safe withdrawal, and equipment removal.
Before every use, inspect the cylinder and cylinder pressure, facepiece and seal, hoses, valves, regulator, pressure indicator, warning system, harness, and associated breathing components according to the manufacturer's instructions.
Cylinder filling, hydrostatic testing, inspection, servicing, storage, and component replacement must be carried out in accordance with the manufacturer's requirements and applicable regulations.
Never rely solely on the nominal breathing duration when planning entry into a hazardous atmosphere. Appropriate risk assessment, air-management procedures, emergency backup, and safe-exit planning are essential.
