Chemical Bunding Requirements and Workplace Guidelines

Workplace safety is an uncompromisable priority, demanding utmost attention for safeguarding employees and the environment from potential risks. In the face of evolving industries and emerging challenges, it becomes increasingly critical to establish safety measures to effectively counter the hazards posed by chemicals.

That’s where chemical bunding comes into play. This ingenious technique plays a pivotal role in preventing and mitigating incidents by confining hazardous substances within designated areas, ensuring their containment and minimising the impact on personnel and surroundings.

Join us as we embark on an enlightening exploration of chemical bunding requirements and their contribution towards workplace safety, unveiling the importance of establishing robust protocols and guidelines to ensure the safe handling, storage, and containment of hazardous substances.

What is Chemical Bunding?

Chemical bunding or secondary containment refers to the practice of creating a physical barrier or containment system around storage areas, equipment, or processes where hazardous substances are handled. The purpose of chemical bunding is to prevent the accidental release or leakage of these substances into the environment, ensuring their confinement within a designated area.

Types of Bunding

Different types of bunding systems can be implemented based on the specific requirements of a workplace:

• Containment Berms or Dikes: Containment berms are raised structures made of concrete, steel, or earth that surround storage areas or equipment. They are designed to contain spills and prevent the spread of hazardous materials.

• Bunded Pallets or Trays: Bunded pallets or trays are platforms with built-in containment that are used to store smaller containers, drums, or barrels. They have a sump or tray at the bottom to capture any leaks or spills.

• Bunded Tanks or Containers: Bunded tanks or containers are used for storing larger quantities of hazardous substances. They consist of an inner tank that holds the chemical and an outer bund or containment structure that acts as a secondary barrier to contain any leaks or spills.

Advantages of Chemical Bunding

Implementing chemical bunding measures in the workplace offers several advantages:

• Environmental Protection: Chemical bunding helps prevent hazardous substances from contaminating soil, waterways, or nearby ecosystems in the event of a spill or leak. It minimises the risk of environmental pollution and ensures compliance with environmental regulations.

• Employee Safety: By containing hazardous materials within designated areas, chemical bunding reduces the risk of accidental exposure to employees. It provides a physical barrier that helps to prevent spills from spreading, allowing for safer cleanup procedures.

• Regulatory Compliance: Chemical bunding is often a legal requirement imposed by regulatory authorities. Adhering to bunding guidelines ensures compliance with safety and environmental regulations, protecting organisations from potential penalties or legal consequences.

• Damage Prevention: Bunding systems act as a safeguard against property damage by containing spills and leaks. They help minimise the financial impact of cleanup, remediation, and potential downtime resulting from accidents involving hazardous substances.

Legal Requirements for Chemical Bunding in the Workplace 

In Australia, ensuring compliance with legal requirements is essential for maintaining workplace safety and upholding environmental standards. The specific legal obligations for chemical bunding can vary based on the industry and the nature of the hazardous substances involved.

Workplace Health and Safety (WHS) Regulations

Under the Workplace Health and Safety (WHS) Regulations in Australia, employers are legally obligated to prioritise the safety of their employees by creating a work environment free from hazards, including the proper handling and containment of hazardous substances. This includes implementing effective chemical bunding measures to prevent spills or leaks, conducting risk assessments, providing necessary training and information to employees, and ensuring regular maintenance and inspections of bunding systems. By fulfilling their duty of care, employers contribute to the well-being and protection of their workforce and demonstrate a commitment to workplace safety.

Environmental Protection Regulations

Organisations in Australia are subject to environmental protection regulations that aim to prevent pollution and degradation of the environment. These regulations often require businesses to implement effective chemical bunding systems to contain hazardous substances and prevent their release into soil, waterways, and the air. By complying with these regulations, organisations contribute to the preservation of ecosystems, safeguard human health, and demonstrate their commitment to sustainable and responsible practices.

Industry-Specific Regulations

In addition to WHS and environmental protection regulations, Standards Australia has developed specific regulations and guidelines specific regulations and guidelines regarding chemical bunding based on the nature of operations and the substances involved in various industries. For example, the oil and gas industry typically has stringent regulations for bunding due to the high risk of spills and leaks. Requirements may include secondary containment systems around storage tanks, bunding for transfer areas, and regular inspections and maintenance. Similarly, industries involved in chemical manufacturing and storage are also subject to strict regulations. These may include specific requirements for the design, construction, and capacity of bunding systems, spill response plans, and regular integrity testing.

Non-compliance with chemical bunding regulations can lead to severe consequences, such as:

• Fines and Penalties: Regulatory authorities may impose substantial fines and penalties for non-compliance, which can vary depending on the severity and frequency of violations.

• Legal Action: Non-compliance can result in legal action, including civil lawsuits, injunctions, and enforcement orders, which can be costly and damaging to an organisation’s reputation.

• Operational Disruption: Failure to comply with regulations may lead to operational disruptions, such as temporary or permanent closure of facilities, suspension of permits, or the inability to obtain necessary licences.

• Environmental Damage and Liability: If a chemical spill or release occurs due to inadequate bunding measures, the organisation may be held liable for the resulting environmental damage, cleanup costs, and potential health and safety risks to individuals and communities.

To avoid these consequences, organisations must diligently assess and understand the specific legal requirements for chemical bunding in their industry. It is crucial to implement and maintain appropriate bunding systems, conduct regular inspections and audits, and stay updated with regulatory changes to ensure compliance and prioritise workplace safety.

Benefits of Chemical Bunding

Chemical bunding offers several key benefits that contribute to workplace safety and environmental protection. Let’s explore three key advantages of implementing effective chemical bunding measures:

1. Contain the leak or spill 

One of the primary benefits of chemical bunding is its ability to contain leaks or spills of hazardous substances. By creating a physical barrier around storage areas or equipment, bunding systems prevent the spread of chemicals, limiting their impact on the surrounding environment. This containment helps minimise the potential for contamination of soil, waterways, and air, reducing the risk of harm to employees, communities, and ecosystems.

2. Minimise the risk of fire or explosion 

Chemical bunding plays a vital role in mitigating the risk of fire or explosion associated with hazardous substances. By confining the leaked or spilt chemicals within a designated area, bunding systems prevent their contact with ignition sources, such as sparks or open flames. This containment significantly reduces the chances of fire incidents or explosions, safeguarding the well-being of workers and the integrity of the workplace.

3. Aid the recovery and clean-up of chemicals 

In the unfortunate event of a chemical spill or leak, effective chemical bunding systems facilitate the recovery and clean-up process. The containment provided by bunding allows for easier and more efficient containment and collection of spilt substances. It helps prevent further spreading and enables specialised response teams to safely and effectively manage the clean-up, minimising the impact on the environment and allowing for faster restoration of normal operations.

These benefits not only protect the well-being of employees and the environment but also contribute to regulatory compliance and the overall sustainability of the workplace.
