Handling flammable liquids in manufacturing is a high-risk process that requires strict safety measures. Certain liquids, such as gasoline, ethanol and solvents, have low flash points and / or low conductivity. Industries such as manufacturing, automotive and pharmaceuticals rely on these flammable substances, making it essential to use the right equipment and follow stringent protocols to avoid accidents.
The flash point is lowest liquid temperature at which, under certain conditions, a liquid gives off vapours in a quantity capable of forming an ignitable air/vapour mixture. Flammable liquids with flash points at or below 100°F (37.8°C) are especially volatile and prone to generating flammable vapours. Gasoline and acetone, for example, can release enough vapours to ignite even at low temperatures (should an ignition source be present), making proper storage and transfer critical. Some highly flammable liquids have flash points below 0 deg C.
To maintain a safe workplace, choose pumping and mixing equipment that minimises vapour release and eliminates ignition sources. This is especially important when pumping flammable liquids with low conductivity, as these liquids will take more time to dissipate any static charge generated within them during the transfer process.
Improperly transferring flammable liquids can lead to serious accidents, including fires and explosions. Static electricity is a common hazard during liquid transfer, as friction from pumping can create static build up. A spark from static discharge may ignite flammable vapours if operators fail to ground pumps and containers properly. Additionally, using uncertified or damaged equipment can cause leaks, increasing the risk of vapour exposure and ignition. It’s essential pumps designed for use in explosive atmospheres are used to avoid these dangers.
FLUX manufactures ATEX-certified pumps, which are specially designed for use in explosive atmospheres. These pumps reduce risk of sparks and minimise risk of static discharge during the transfer process, significantly reducing fire risks. With grounding and bonding features built in, FLUX pumps ensure safe, reliable handling of volatile and flammable liquids. The materials used in these pumps are also resistant to specific chemicals, reducing the potential for leaks.
In the UK, handling flammable liquids requires compliance with strict regulations set by the Health and Safety Executive (HSE). These regulations, including the Control of Substances Hazardous to Health (COSHH) and DSEAR (Dangerous Substances and Explosive Atmospheres Regulations) require employers to assess and control risks to safety from fire, explosion and substances that are corrosive to metals.
The regulations require organisations to conduct risk assessments, Zoned area classifications, implement safety measures and provide proper employee training. Using ATEX-certified equipment for flammable liquids not only enhances safety but ensures compliance with these essential regulations. For more information on ATEX certifications and how they apply to your operations, visit our ATEX guide.
Safely handling and transferring flammable liquids in manufacturing requires the right equipment, adherence to safety protocols and compliance with regulations. By choosing FLUX ATEX-certified pumps and motors, businesses can reduce the risks of fire, explosion and environmental harm, while maintaining operational efficiency. Prioritising safety helps protect both employees and valuable assets, ensuring a secure and compliant workplace.
Diaphragm pumps, also known as membrane pumps, are one of the most versatile pump types available. They are widely used in many industries, for good reason. They are robust, compact and available in wide range of materials and sizes. In addition, they are self-priming and have dry-run capability. Plus, they are suitable for wide ranging […]
Brewing beer is one of the oldest beverage production methods, requiring specialised beer brewing equipment. In contrast to grape juice that ferments on its own, beer production involves multiple steps from grain to glass, thereby making the brewing industry a pioneer in technological innovation. Today, sophisticated systems produce and bottle beer hygienically and gently. Additionally, […]
