Certified to ISO 12402-3, it provides 170N buoyancy with manual inflation through a pull-handle mechanism.

Sigma 170N Manual Lifejacket – Key Features

The Sigma 170N manual lifejacket combines reliable flotation with simple operation.

Unlike automatic models, this version requires manual activation. Consequently, the wearer must pull the activation handle to inflate the chamber.

Key features include:

• 170N rated buoyancy.
• Manual inflation through a pull-handle mechanism.
• ISO 12402-3 certification.
• Single inflatable buoyancy chamber.
• Oral inflation tube with valve.
• Durable red protective outer cover.
• Lightweight construction for comfortable wear.
• Adjustable webbing for secure fitting.
• High-visibility inflatable chamber.
• Retroreflective material for improved visibility.
• Integrated whistle for emergency signalling.
• Compact design for convenient storage.
• Easy repacking following approved servicing procedures.

Manual Inflation and Emergency Flotation

The LALIZAS Sigma 170N features a manually operated inflation system.

To inflate the lifejacket, the wearer pulls the activation handle. This action releases compressed CO₂ into the inflatable chamber.

Once inflated, the chamber provides buoyancy to support the wearer in the water.

In addition, an oral inflation tube allows further inflation when appropriate.

Manual activation helps avoid unwanted inflation caused by water exposure. However, the wearer must remain capable of activating the mechanism.

Important: This lifejacket does not inflate automatically upon immersion. Therefore, it may not be suitable where automatic activation is required.

Lightweight Construction and Comfortable Fit

The Sigma 170N lifejacket features a compact design suitable for regular onboard wear.

Its adjustable webbing helps achieve a secure fit. Meanwhile, the lightweight outer cover reduces unnecessary bulk during movement.

The durable red protective cover encloses the inflatable chamber during normal use.

Furthermore, its practical construction makes the lifejacket easy to handle and store.

This model is intended for adult users and does not include an integrated safety harness or crotch strap.

Visibility and Integrated Safety Features

The LALIZAS Sigma inflatable lifejacket incorporates essential emergency safety equipment.

Its inflatable chamber uses high-visibility material to improve identification in the water.

Retroreflective elements provide additional visibility in poor lighting conditions. In addition, the integrated whistle allows the wearer to attract attention.

Main safety features include:

• High-visibility inflatable chamber.
• Retroreflective material.
• Emergency whistle.
• Manual CO₂ inflation system.
• Oral inflation provision.
• Adjustable fastening webbing.

Together, these features support personal flotation and emergency signalling.

Inspection, Maintenance and Rearming

Regular inspection is essential for reliable lifejacket performance.

Before use, inspect the protective cover, webbing, fastening components, and inflatable chamber.

Check the CO₂ cylinder and manual inflation mechanism according to the manufacturer’s instructions.

Furthermore, ensure that the activation handle remains accessible and that the inflation system is ready.

After inflation, the lifejacket requires inspection and rearming before reuse.

Only approved replacement cylinders and compatible inflation components should be installed.

Important Safety Information

The Sigma 170N Manual Lifejacket requires the wearer to activate inflation manually.

Therefore, it should not be treated as a substitute for an automatically inflating lifejacket when automatic activation is required.

Always check the suitability of the lifejacket for the intended activity and operating conditions.

Follow the manufacturer’s instructions concerning fitting, inspection, maintenance, and rearming.
