Intermediate Bulk Containers (IBCs) are a cornerstone in the storage and transport of liquids across various industries in New Zealand. Ensuring the safe containment of these substances is paramount, not only for environmental protection but also to comply with stringent health and safety regulations. This is where IBC bunding, a form of secondary containment, plays a critical role.
Understanding IBC Bunding
IBC bunding refers to the secondary containment systems designed to capture spills or leaks from the primary IBC storage units. These bunds act as a safeguard, preventing hazardous substances from escaping into the environment or posing risks to personnel. In essence, if an IBC were to fail, the bund would contain the released liquid, allowing for safe recovery and disposal.
Safety Imperatives
The primary purpose of IBC bunding is to mitigate the risks associated with the storage of hazardous liquids. Key safety considerations include:
Spill Containment: Effective bunding ensures that accidental releases are confined, reducing the potential for environmental contamination and workplace hazards.
Fire Hazard Reduction: For flammable substances, bunds are designed to minimize the surface area of any spill, thereby reducing the risk of ignition and subsequent fire.
Structural Integrity: Regular maintenance and inspection of bunds are essential to ensure they remain robust and free from damage that could compromise their effectiveness.
WorkSafe Compliance in New Zealand
Adherence to New Zealand's health and safety regulations is non-negotiable for businesses handling hazardous substances. The Health and Safety at Work (Hazardous Substances) Regulations 2017 outline specific requirements for secondary containment:
Capacity Requirements: Bunds must have a capacity of at least 110% of the largest container stored within them. This ensures that even in the event of a complete IBC failure, the bund can fully contain the spill.
Design Standards: Secondary containment systems should be constructed to prevent any leakage and be compatible with the stored substances to avoid reactions that could compromise the bund's integrity.
Certification: Facilities with stationary container systems exceeding specified thresholds are required to obtain certification from a compliance certifier, ensuring all systems meet the legal standards.
Implementing Effective IBC Bunding Solutions
For manufacturers and engineers, selecting the appropriate IBC bunding system involves:
Assessing Chemical Properties: Understanding the nature of the stored substances to choose materials for bund construction that resist corrosion and chemical reactions.
Evaluating Storage Volumes: Ensuring bunds are adequately sized to meet or exceed the 110% capacity requirement.
Considering Environmental Factors: For outdoor storage, bunds should be designed to withstand weather conditions, potentially incorporating features like rain covers to prevent overflow due to precipitation.
Regular Maintenance: Establishing routine inspection protocols to identify and rectify any wear or damage to the bunding systems promptly.
Conclusion
Implementing compliant and effective IBC bunding is not only a regulatory requirement in New Zealand but also a critical component of workplace safety and environmental stewardship. By prioritizing robust secondary containment measures, businesses can protect their workforce, the environment, and their operational integrity.
