LAPS Stunning System - Top 25 FAQs

1. What is LAPS®?

LAPS® is a stunning method where atmospheric pressure in a sealed chamber is gradually reduced, inducing unconsciousness in birds humanely without gas or electrical contact.

2. How does the LAPS® process work?

Birds in drawers/modules are placed in a sealed chamber where pressure slowly decreases, inducing mild hypoxia and a controlled loss of consciousness.

3. How long does a LAPS® cycle take?

Typical decompression cycles last around 4–5 minutes, depending on bird size and welfare settings.

4. Do birds experience distress?

Independent studies and welfare assessments indicate minimal stress during LAPS®, with fewer adverse behaviours compared with gas or electrical stunning.

5. Can the LAPS® cycle be interrupted?

Yes — systems are designed with automatic fail-safes that either complete or abort cycles in the event of interruptions.

6. Is LAPS® considered humane?

Yes — LAPS® is scientifically validated and recognised by authorities, including EFSA and welfare bodies, for its welfare benefits.

7. How does LAPS® compare with gas stunning?

Unlike gas methods, LAPS® avoids aversive atmospheres and eliminates the risks and regulatory burdens of handling gases.

8. How does it compare with electrical stunning?

LAPS® avoids shackling and electrical current, reducing stress and physical handling prior to unconsciousness.

9. Does LAPS® support welfare certifications?

Yes — if operated to approved welfare standards, systems can support schemes like Red Tractor or RSPCA Assured.

10. Are there mechanisms to monitor bird welfare?

Chambers use pressure sensors and cycle data logging to ensure consistent, welfare-compliant decompression profiles.

11. What capacity can LAPS® handle?

Capacity depends on drawer configuration and chamber size, typically engineered for commercial speeds (e.g., 4,000–12,000 birds/hr).

12. How does LAPS® impact meat quality?

Reduced pre-stun stress lowers bruising and muscle pH variability, improving meat colour, texture, and shelf life.

13. Can LAPS® integrate with existing systems?

It is designed to integrate with handling systems such as ProLoad and other standard processing lines.

14. Does LAPS® require special gases or supplies?

No — it operates without CO₂ or any other gas, eliminating the need for supply and storage.

15. Does it reduce environmental impact?

Without gas use, operations see lower emissions and no gas-related risks.

16. Is LAPS® safe for operators?

Yes — there’s no gas exposure risk, and safety procedures ensure safe access and operation of chambers.

17. What happens if there’s a power failure?

Systems include emergency protocols and fail-safe pressure release to maintain welfare and safety.

18. Are operators trained?

Operators should be trained in use, welfare principles, and emergency procedures.

19. Can controls and data be exported?

Many systems log cycle data and welfare parameters for audit and compliance reporting.

20. Is noise or vibration a concern?

LAPS® chambers operate quietly with minimal disturbance compared with some traditional systems.

21. How often should the system be serviced?

Routine servicing is recommended quarterly, with daily operator checks.

22. Do you recommend spare parts on site?

Yes — having an essential set of spares like seals and sensors helps minimise maintenance impact.

23. Can heavy or large birds be handled?

The system is currently approved for broilers of 4kg or less in weight

24. Is maintenance complex?

Systems are designed for easy access, diagnostic checks, and reduced downtime.

25. Can LAPS® be upgraded over time?

Yes — expansions and software upgrades can support future throughput or compliance needs. (based on system architecture)
