Study Notes

Overview of the PNS for Agricultural Structure – Lairage – Swine

Provides guidance on designing lairage for swine slaughterhouses aimed at human consumption.
Draft reviewed through stakeholder consultations via online platforms.
Aims to assist national and local authorities, engineers, traders, processors, and stakeholders.

Significant Changes from Previous Standard (PAES 410:2000)

Standard scope revised to specifically focus on swine.
Provisions for ruminants removed, streamlining the standard.
New terms and definitions added in Clause 3.
Construction and structural requirements included as Clause 7.
Provisions amended for unloading areas, lighting, drainage, fencing, gates, dividers, storage, and waste disposal.
Annexe A amended; new drainage design (Annex B) and concrete cover design (Annex C) included.
Occupational Safety and Health Standard rules for worker safety appended as Annex D.

General Requirements and Objectives

Establishes requirements for site selection, design, and construction.
Outlines essential operational requirements for lairage facilities.
Focus on the protection and convenience of slaughterhouse personnel.
Emphasizes animal welfare throughout the operation.

Key Design Specifications

Unloading dock must feature solid side fences with a gap for easy washing.
Separate entrance gates or ramps required for swine not unloaded directly.
Ramp width varies based on unloading method: 0.35 m to 0.43 m for single-file, wider for double-file.
Adequate and uniform lighting required in holding pens, ramps, and raceways for effective animal handling.

Drainage Requirements

Each pen should have individual drainage outlets with a 2% slope leading to the main drainage line.
Catch basins needed before wastewater enters treatment facilities; must have easy-to-clean strainers.
Wastewater canals outside lairage should have detachable concrete covers.

Fencing and Structural Safety

Gates and fences made with rust-resistant metal pipes; outside walls constructed from concrete.
Protruding nails and sharp edges must be avoided to prevent injuries to swine.
Safety features for gates include counter-weighted vertical slide gates and padded bottoms.

Noise Exposure Guidelines

Permissible noise exposure levels defined by maximum exposure duration per day and corresponding sound levels (dB(A)).
Noise exposures of less than 90 dBA not covered by restrictions; detailed color requirements for cumulative exposure need consideration.

Conclusion

The PNS for Agricultural Structure – Lairage – Swine standard is formulated to enhance the design, operation, and welfare aspects of swine slaughterhouses, ensuring safety for both personnel and animals.
