Mitigating Hex Chromates

The ROI of Mitigating Hexavalent Chromium Exposure

We previously explored the serious health hazards and bottom-line risks that metal fabricators and other manufacturers face from hexavalent chromium exposure. Fortunately, there are cost-effective, clean air solutions to safeguard employees, increase overall productivity and profits.

Duroair’s modular industrial air filtration solutions isolate and capture dangerous hexavalent chromium particulates that can bring production to a grinding halt. Below are a few examples of how this technology can improve operational processes and increase manufacturing clean air ROI.

Decrease Downtime

If employees become too ill to work, downtime is inevitable. Traditional methods to safeguard workers can also result in lost uptime. For many aerospace and aviation manufacturers, their only option for meeting OSHA’s Permissible Exposure Limit (PEL) is to open all of their hangar doors during sanding and painting to release the dangerous hexavalent chromium particulates when parts or planes cannot be moved into a traditional paint booth.

All other manufacturing processes must be put on hold until these tasks are complete, and it can take several hours before workers are allowed to re-enter the building and get back to work.

With Duroair’s clean air solutions, manufacturers can safely isolate painting and coating processes to not only protect the workers performing these tasks, but prevent the toxic VOCs and hex chromates from escaping the sanding/painting enclosure. Additional workflows can proceed unimpeded, and there’s no need for workers to spend hours in a break room waiting for dangerous toxins to vent outside.

Improve Productivity

Modular industrial air filtration improves productivity because the flexible, clean air enclosures can be moved when and where hexavalent chromium-producing processes are taking place. For aerospace and aviation manufacturers, this means additional work teams can disassemble aircraft components and conduct repairs, while sanding and painting is taking place.

There’s the added benefit of a controlled, clean air flow, such as Duroair’s Taper Draft Airflow Technology that pulls hex chromate particles and dust directly into the air filtration chamber, so the particulates don’t settle on the workpiece or the shop floor. Employees don’t have to waste valuable man-hours cleaning dirty floors and repairing dust-clogged machinery. This technology even speeds up drying times for water-based paints and coatings, without the use of additional quick-dry agents.

Reduce Material Handling

For large aircraft, submarine, or other bulky metal components, mitigating hexavalent chromium risks often requires extensive material handling to move assemblies into and out of dedicated clean air enclosures. But, what if you could bring clean air to each workpiece?

Duroair’s customizable combination of non-vented air filtration systems and retractable enclosures create self-contained work environments for helicopters, airplane assemblies, and other larger parts for sanding and painting.

This technology also eliminates the need to vent air-conditioned or heated air to release hex chromate particles. With Duroair’s industrial air filtration, clean air is recirculated back into the building without the need to use makeup air.

Expand Production Capability

Per the PEL, OSHA limits how many times per year industrial facilities can vent hexavalent chromium particulates. Without a process to isolate and capture all these particulates, manufacturers are only allowed to complete a specific number of sanding, coating, or painting processes per year to stay in compliance.

With Duroair’s six-stage filtration technology, 100% of the offending hex chromates are safely contained, removing the limitations on the number of manufacturing processes and task consumables, such as chromium-based aluminum coatings and rust-prevention paints. Facilities can significantly increase their production capability without being handcuffed by regulatory requirements.

Guarantee Indoor Air Safety for True ROI

Compromised safety leads to a compromised bottom line. Even one workplace accident or serious illness due to hexavalent chromium exposure can risk thousands or even millions of dollars in legal fees and OSHA and EPA regulatory action.

But, with Duroair’s hexavalent chromium containment technology, manufacturers can protect their most valuable assets – their employees. This clean air technology goes beyond OSHA and NESHAP 319 requirements to cost-effectively mitigate health risks that can negatively impact productivity and potential profits.

A safe workplace means employees can successfully complete critical tasks such as:

  • Airplane repair and refurbishing
  • Aircraft wing and component replacements
  • Engine repair preparation
