Understanding the Fumes Generated in Oil Misting Processes

In industrial environments where machinery is an integral part of daily operations, ensuring a safe and healthy workspace is crucial. As technology advances and production speeds increase, the challenge of managing workplace air quality becomes even more critical. Among the various concerns, airborne contaminants such as oil mist represent a significant health risk that can often be overlooked.

Addressing these risks effectively, not only improves employee safety but also contributes to the overall efficiency and longevity of machinery. In this blog, we will explore the implications of oil mist in the workplace and introduce advanced machinery to eliminate these airborne hazards.

What is Oil Mist?

Oil mist is generated during operations where oil is used as a coolant or lubricant in machinery processes. Common in the automotive and metalworking industries, these fine droplets can form clouds of mist that may linger in the air of a facility. The size of these droplets typically ranges from less than 1 micron to about 10 microns, allowing them to be easily inhaled by workers, which poses significant health risks.

Health Risks Associated with Oil Mist

Exposure to oil mist can lead to serious health conditions such as:

• Respiratory problems: Inhalation of oil mist can cause lung diseases, including hypersensitivity pneumonitis (HP), a condition characterised by inflammation of the lung tissue.
• Dermatitis: Oil mist can settle on the skin, leading to irritation and dermatitis.
• Other risks: Chronic exposure may also contribute to an increased risk of certain types of cancer.

Is Oil Hazardous?

While oil is essential in many industrial processes, it does have hazardous properties that must be carefully managed. Beyond the immediate risks of oil mist and smoke, oils can pose environmental hazards if not disposed of properly, potentially contaminating water sources or soil. Fire risk is another concern, as oil can ignite under certain conditions, emphasising the importance of proper storage and handling procedures to ensure safety.

Oil Mist and Oil Smoke Formation Explained

Oil Mist: Oil mist forms during metalworking processes, such as milling and drilling, when metalworking fluids (MWFs) encounter fast-rotating tools. When high-speed tools operate with oil, they create fine oil droplets, which are then dispersed into the air around the machinery.

Oil Smoke: Oil smoke can occur during operations that involve hot temperatures, such as grinding. As the metal parts heat up, the temperature can cause the MWFs to overheat, "burn," and degrade. This process produces even smaller droplets, known as oil smoke, which occur when the droplet diameter is smaller than that of oil mist.

Effective Management of Oil Mist

Controlling oil mist involves a combination of engineering controls, proper maintenance practices, and safety equipment. Installing high-efficiency extraction systems like HEPA Filters provided by Purex can capture oil mist at the source, preventing it from dispersing into the workplace environment.

Regular maintenance ensures they operate effectively, reducing the amount of oil mist generated. Educating employees on the risks associated with oil mist and proper safety practices helps mitigate potential health impacts.

How To Stop Smoke Oil

Oil smoke, a finer byproduct of oil mist, often occurs during high-temperature machining processes and can be more hazardous due to its smaller particle size and higher chemical reactivity. To combat oil smoke, workplaces can implement robust extraction and filtration systems like those we offer, equipped with HEPA filters and carbon filters designed to capture these fine particles. Additionally, effective machine operation settings and using high-quality cutting fluids can reduce the generation of oil smoke.

HEPA Filters: Purex's Advanced Filtration Technology for Oil Mist Control

Purex utilises advanced filtration technology, including HEPA (High-Efficiency Particulate Air) filters, to tackle airborne oil mist effectively. In industrial settings where machinery operations produce oil mist, HEPA filters are designed to draw in contaminated air, pass it through the HEPA filters where the oil mist is trapped, and then circulate the purified air back into the workplace.

This not only helps in maintain a healthier environment but also enhances operational efficiency by preventing the buildup of oily residues on equipment and surfaces. If you would like to know more about how Purex systems can help extract fumes from your commercial setting, get in touch.
