ISO 20024:2020

Overview

ISO 20024:2020 - Solid biofuels - Safe handling and storage of solid biofuel pellets provides principles and requirements for the safe handling and storage of pelletized solid biofuels in commercial and industrial settings. Using a risk-based approach, the standard addresses operations from the pellet production cooler outlet through distribution and to industrial end‑users up to the point pellets are fed into fuel preparation or combustion systems. It excludes the safety of transportation itself but includes unloading/loading operations, detection and suppression system guidance, preparatory measures for firefighting, and fire/explosion incident management.

Key Topics and Technical Requirements

ISO 20024:2020 organizes practical safety guidance across design, operation and emergency planning. Key technical topics include:

• Risk management framework: hazard identification, risk estimation, evaluation and risk reduction measures tailored to pellet storage and handling.
• Design and construction requirements: site-specific risk areas, material handling infrastructure and protective design considerations.
• Operation, maintenance and documentation: safe operating procedures, housekeeping, maintenance regimes, and visitor/contractor guidance.
• Conveyor systems and transfer points: detection, fire protection, explosion protection and preparatory measures for transfer equipment.
• Silos, bunkers and warehouses: detection and temperature/gas monitoring, fire and explosion mitigation and system design recommendations.
• Detection and suppression systems: guidance on sensors, temperature/gas monitoring, inerting, and arrangement of detection/suppression equipment.
• Emergency preparedness and firefighting: preparatory measures that enable safe and efficient firefighting operations; incident management guidance.
• Informative annexes: supply‑chain descriptions, self‑heating and off‑gassing, dust hazards, ventilation for cooling, inert gas distribution, sensor layouts and a sample risk assessment.

Practical Applications - Who Uses It

ISO 20024 is practical for organizations that handle pelletized biofuels:

• Pellet production plants (from cooler outlet to loading)
• Commercial distributors (from receiving to loading)
• Industrial end‑users (from receiving to fuel preparation/combustion) Typical users:
• Safety and EHS managers
• Facility and process engineers
• Fire protection and explosion mitigation specialists
• Design consultants and architects for storage facilities
• Insurers, auditors and regulators evaluating compliance and operational risk

Use cases include designing safer storage silos and bunkers, specifying detection and suppression systems, preparing emergency response plans, performing risk assessments, and improving housekeeping and maintenance to reduce fire and explosion risk.

Related Standards (if applicable)

ISO 20024 complements broader risk management and fire safety standards, national building and fire codes, and industry guidance on explosion protection and dust control. Organizations typically apply ISO 20024 alongside local regulatory requirements and specialist standards for electrical and explosion‑proof equipment.
