Foreword
In 2017, the Bureau of Agriculture and Fisheries Standards (BAFS) initiated the
amendment of the Philippine Agricultural Engineering Standard (PAES) on
Slaughterhouse Equipment – Stunning Box/Knocking Pen – Specifications (PAES
513:2008) upon the endorsement of the PAES Task Force. A Technical Working Group
(TWG) was created through Special Order (SO) No. 487, series of 2017 (Creation of the
TWG for the development of PNS for Cattle Restrainer and for the revision of PAES for
Slaughterhouse and Lairage), SO No. 322, series of 2019 (Creation of Technical
Committee [TC] and TWG for Agriculture and Fishery Products and Machinery, Tools,
and Equipment), and SO No. 280, series of 2021 (Creation of TWG for the Development
of Philippine National Standards [PNS] For Agriculture And Fishery Products, Machinery,
and Equipment). This TWG was composed of representatives from the government
agencies, academe, and private sector. The revised PAES, which is now a BAFS PNS,
aimed to provide guidance to national and local authorities, engineers, technical
personnel, traders, manufacturers, processors, and other relevant stakeholders on the
restrainer design for the slaughterhouse of large ruminants intended for human
consumption. The final draft standard was reviewed and finalized through a series of
stakeholder consultations and TWG meetings conducted via online platforms.
This PNS/BAFS includes the following significant changes compared to the previous
PAES:
1. Modification of format in accordance with ISO/IEC Directives Part 2 eighth edition;
2. Change of name of the slaughterhouse equipment from “Stunning Box/Knocking
Pen” to “Large Ruminant Restrainer”;
3. Revision of the scope to include only general restrainers installed in
slaughterhouses and limit the large ruminants to carabao and cattle only;
4. Modify classification of restrainer;
5. Inclusion of these references: “PAES 192:2016 Agricultural Machinery –
Guidelines of After-Sales Service” and “Republic Act (RA) 8485 as amended by
RA 10631”
6. Revision and deletion of some terms and definitions under Clause 3 and use the
term “restrainer” throughout the document;
7. Addition of figures for different classifications of restrainer;
8. Deletion of the sketch illustrations for restrainer parts;
9. Deletion of the provision for the rotating-type cattle restrainer;
10. Inclusion of the butcher’s platform/flooring and discharge landing platform as
integral component of the cattle restrainer;
11. Addition of the provision for emergency stop;
12. Addition of noise level for ruminant and operator’s safety;
13. Deletion of the provision for the prohibition of paint; and
14. Inclusion of Occupational Safety and Health Standard (OSHS) Rule 1074.01-
1074.03 requirements attached as Annex A.
