Schedule 2 PIB Guidelines

OPCW recommends that the following information is included in the Pre-Inspection Briefing for a Schedule 2 facility.

A. Introduction of participants 

  • Host team 

    • Names and functions 
  • Facility personnel 

    • Participants names and functions 

B. General information about the facility  

  • Brief history of the facility and basic information 

  • Type of industry (e.g., fertilizers, pharmaceuticals, pesticides, plasticizers, paints, soaps, etc.) 

  • Management, organisation, operations, environment 

  • Certificates of accreditations (e.g., ISO, FDA, etc.) 

  • Security features (e.g., fence/wall, CCTV, patrols, others) 

  • Any changes in the facility (operational, organisational) since the last inspection (if applicable) 

  • Number of employees 

  • Aerial view map indicating: 

    • Location in relation to Point of Entry (POE)

    • Distance from POE  

  • Facility layout indicating: 

    • Boundaries and gates 

    • Total area of the facility 

C. Facility safety measures 

  • Related to inspection conduct: 

    • No operation/touching of equipment 

    • Need for escort 

  • Related to facility: 

    • Safety hazards and safety procedures 

    • Specific personal protective equipment 

    • Emergency alarms and response procedures  

    • Evacuation routes 

    • Assembly points 

    • Location of medical facilities and nearest hospital (in km) 

D. Logistics and administrative information  

  • Working hours: administration and operations 

  • Working spaces 

    • Inspectors and escort team working spaces (offices), and briefing areas 

    • Set-up inspection team office (lockable, power supplied, available during the entire inspection period, equipped with desks and chairs) 

  • Communications/mobile phone policy 

  • Transportation 

  • Lodging and meals 

  • Security and badging procedures 

E. Physical layout 

  • Provide facility layout or comprehensive list indicating the following: 

    • Declared Schedule 2 facility(s) 

    • Schedule 3 and DOC/PSF facility(s) (if any) 

    • Common infrastructure (e.g., QC/R&D laboratories, waste treatment, maintenance, warehouses, pilot facilities, medical facilities, etc.) 

    • Non-declarable facilities (e.g., formulation, polymers, inorganic chemicals, etc.) 

    • Other companies/facilities which may be physically located within the same boundary, but may not (operationally) form part of the facility 

    • GPS reading point (if coordinates are declared) 

F. Detailed information – quantitative information 

  • Declaration figures (indicate any changes/discrepancies in relation to the declared data) 

    • Identification of Schedule 2 facility(s) (e.g., building/structure, location, etc.) 

    • Main activities of Schedule 2 facilities(expressed in terms of PGC

    • Activities in relation to Schedule 2 chemicals (production (PROD) processing (PROC), consumption (CONS)) 

    • Characteristics of the facility(s) (dedicated, multipurpose) 

    • Other activities (expressed in terms of codes B04, B05, B06) 

    • Production capacity and method of calculation (if applicable) 

    • Specific information in each Schedule 2 chemical (IUPAC/trade names) 

G. Overview of declared Schedule 2 activities 

  • Consider inclusion of the following for each Schedule 2 facility: 

    • Chemical PROD, PROC, CONS quantities (e.g., annual summary) 

    • Types of chemical reaction(s) with reaction schemes/process diagrams (including downstream processes, e.g., filtration, distillation, centrifugation, etc.) 

    • Materials of construction (e.g., SS, CS, Hastelloy, etc.) 

    • Mode of operation: batch/continuous 

    • Dedicated/multipurpose 

    • Type of control (e.g., manual, automatic, etc.) 

    • Associated infrastructure (e.g., tank farms, laboratories, etc.) 

    • Specific safety features (e.g., detectors, PPE) 

  • List all scheduled chemicals on the facility, even if under threshold levels 

H. Records to be reviewed 

  • The records review process is not part of the PIB and therefore these documents should not be included in the PIB material. 

  • It is highly recommended to have these documents ready at the beginning of the inspection, to optimize the inspection process. 

  • The following is a non-exhaustive list of relevant records generally requested and accessed by OPCW inspectors during the records review process 

Record name 


Certifications (e.g., ISO) and Business Registration documentation  

To verify name, owner, and address of the facility 

Annual/monthly summaries in relation to (PROD, PROC, CONS, Import, Export) 

To verify the level of declared activities, non-diversion 

Batch records/daily inventory data/on-screen data  

To cross-check the integrity of the recording system 

Complete list of chemicals handled on site  

Absence of Schedule 1 and undeclared Schedule chemicals and activities 

Waste analysis/emission analysis 

Non-diversion and absence of any Schedule chemicals 

COA of Schedule 2  

Purity of Schedule 2 chemicals 

Technical data (SDS, basic chemistry) 

Identify chemical structure, composition of a mixture 

Explanation for discrepancy (if any) 

Identification of causes (calibration related, Schedule 2 chemical destruction) 

Methodology for recording systems  

Confirm the process of data capturing and register
