An oxidizing agent is a substance capable of causing oxidation. Widely used in industrial processes, they are essential for the production of items such as fuels and chemicals. These oxidisers are recognised as Class 5.1 dangerous goods and require compliant storage to reduce the many risks that they pose.
Oxidizing agents are diverse substances, ranging from simple molecules to complex compounds.
Here are some common examples of oxidizing agents that you may already be working with:
However, there are many more substances with oxidizing properties.
It's important to handle them with care and follow appropriate safety measures due to their potential hazards. We’ll look at this topic in the next section of our post.
Oxidizing agents are substances that can cause other substances to undergo oxidation, meaning they lose electrons.
While these dangerous goods are essential in various chemical processes, they can also pose serious risk to people, property and environment if not handled and stored in the right way.
Here are some common physiochemical hazards associated with oxidizing agents:
Division 5.1 Oxidising Agents have physiochemical and health hazards and must be placarded appropriately to alert staff members to these hazards.
Some oxidizing agents may also pose other health risks, depending on their chemical properties.
Some may be toxic to humans and animals. Exposure to oxidizing agents may cause irritation, burns or severe health effects, depending on the specific chemical and concentration.
Oxidizing agents can also corrode or degrade living tissues, as well as various materials such as metals and stone. This corrosion can weaken structures, damage equipment and harm humans and the environment.
To determine the best practice storage and handling for oxidizing agents, turn to the relevant Australian Standard.
AS 4326 - The storage and handling of oxidizing agents details all requirements for workplaces managing the risks of oxidizing agents.
When storing your chemicals, make sure the equipment is built for purpose, so the design and construction is specific to the risks posed by the oxidising agents.
Oxidixing agents may be stored indoors or outdoors, depending on your risk assessment and the quantities you hold.
Handling oxidizing agents requires careful attention to safety protocols to minimize the risk of accidents and exposure.
Here are some general guidelines for handling oxidizing agents safely:
REMEMBER: Conduct a thorough risk assessment before working with oxidizing agents to identify potential hazards and implement appropriate control measures to mitigate risks in your workplace.
While there are many considerations when storing oxidizing agents in the workplace, there are some key takeaways to factor into your storage procedures:
IMPORTANT: If oxidizing agents have subsidiary risk or risks, the greatest separation and segregation distances will apply.
The types of oxidizing agent packages stores that are deemed as suitable by the Australian Standards include, but are not limited to:
Due to the cost-effectiveness and simplicity of installing a compliant storage cabinet, the Class 5.1 Oxidizing Agent Storage Cabinets are often a popular solution for indoor storage.
Alternatively, a purpose-built Class 5.1 Outdoor Storage Container can offer adequate protection for the goods if stored in the outdoor environment.
IMPORTANT: Safe storage is only the first step. It’s important to follow proper safety protocols, including conducting risk assessments, providing adequate training to personnel, using appropriate protective measures, and implementing strict storage and handling procedures.
One of the key construction features of an Oxidising Agent Storage Cabinet is the door closing system. Storemasta Class 5.1 cabinets provide self-closing, tight-fitting doors which automatically release if there is a build-up of pressure (chemical reaction) within the storage unit.
Spill containment, double walled sheet steel construction with thermic air barrier, and perforated shelving (to prevent build-up of oxidizing agents in corners or ledges of cabinet) add to the overall control of oxidizing agent storage risks.
Features of an oxidising agent indoor storage cabinet include doors that can release automatically if there is a build up of pressure within the storage equipment.
Mechanical ventilation is required for your Class 5.1 cabinet or bulk store. The ventilation system must be compliant, and exhaust directed away from ignition sources – as well as areas in which people may congregate. The ventilation system must be sufficient to ensure exposure levels are within the limits set by the workplace exposure standards.
REMEMBER: Storemasta Oxidizing Agent Storage Cabinets are equipped with built in flash arrestors and vent openings for mechanical ventilation systems.
To reduce the impact of an accident or spill in the workplace, Emergency Decontamination Equipment is required for stores that hold oxidizing agents.
The appropriate gloves (see the safety data sheet of your substance) and water for hand washing must be provided.
However, we recommend conducting an onsite risk assessment to determine your need for equipment such as safety showers and emergency eyewash stations.
