Improving Safety in Food and Beverage Manufacturing with Explosion-Proof Systems

Improving Safety in Food and Beverage Manufacturing with Explosion-Proof Systems

Tuesday 4 March

The food and beverage industry is a high-risk environment when it comes to fire and explosion hazards due to complex processes, various ingredients and high temperatures. In this article, we will outline the risks your facility may face and how explosion-proof systems can mitigate these hazards.

The Leading Causes of Explosions 

• Combustible dust: Many food products, such as flour, sugar, cornstarch and powdered milk, are highly combustible. If enough of this dust accumulates in an enclosed area and is exposed to an ignition source, a dust explosion can occur. 
• Flammable gases and vapours: Gases used in refrigeration systems, such as hydrogen, methane or ammonia, can leak and pose hazards when combined with a spark.
• Oils and fats: Cooking oils, fats and similar liquids can often be spilt or processed in areas with poor ventilation, increasing the risk of fire and explosion.
• Ethanol vapours and flammable liquids: Distilleries, breweries and wineries that handle large amounts of ethanol are at risk when ignition sources such as open flames, sparks, static electricity or hot surfaces are present.

With this considered, facilities such as flour mills, bakeries, sugar refineries, distilleries and powder production plants are particularly at risk.

How Can You Prevent the Risks?

A key prevention method is the implementation of explosion-proof electrical systems. This includes motors, switches, lighting and ventilation specifically designed to mitigate risks. These systems contain any ignition within the equipment, preventing it from spreading to the surrounding atmosphere.

Explosion-proof electrical systems function by using specially designed enclosures, wiring and components that can operate safely in hazardous atmospheres. Some key features include:

• Sealed enclosures: Electrical components are housed in robust, flameproof casings that can withstand and contain internal explosions without allowing sparks or flames to escape. 
• Intrinsically safe wiring: Low-energy circuits ensure that electrical signals do not generate sufficient heat or sparks to ignite flammable substances. 
• Specialised conduits and fittings: Cable and wiring systems are designed to prevent the release of ignitable substances and maintain a safe operating environment. 
• Temperature control: Components are rated for specific temperature classifications to prevent overheating in hazardous zones. 

By implementing these measures, food and beverage facilities can significantly reduce the likelihood of ignition sources in potentially explosive areas.

The Cost of Non-Compliance 

Failing to adhere to explosion-proof electrical requirements can have serious consequences, including:

• Legal and regulatory penalties: Non-compliance with ATEX and other hazardous area standards can result in substantial fines and legal action. 
• Increased risk of fire and explosion: Without proper safety measures, electrical systems can become ignition sources, leading to devastating accidents.
• Higher insurance costs: Facilities without proper hazardous area compliance may face increased insurance policies or difficulties obtaining coverage. 
• Reputational damage: Safety breaches can damage a company’s reputation and reduce customer and stakeholder confidence.
  
  

How to Upgrade Your Facility

By investing in explosion-proof electrical systems, you can safeguard your operations, ensure regulatory compliance and create a safer working environment for employees.

Upgrading to explosion-proof electrical systems involves a structured approach to ensure compliance and safety. It is essential to work with an accredited hazardous area electrical contractor who can help fulfil your site’s specific requirements.
