Aerospace & Defense
The manufacturing of aircraft parts mostly likely starts with the machining of parts using a CNC machine generating mist and smoke from coolant. The airborne mist can become a breathing hazard in a manufacturing shop. Airborne mist can also create a large maintenance issue with other machines because the mist wrecks havoc with the electronics and the machines operation. If too much mist settles on the shop floor the floors become ice rinks.
Another process which can present a problem with airborne particulate includes grinding, deburring, and polishing of many different sized parts, shapes, and materials such as steel, aluminum, titanium, magnesium, etc. Aluminum, titanium, and magnesium are flammable metals, the dust from these materials are very explosive. The other process would be the welding of various materials such as aluminum, manganese, chromium, and other materials producing fume that is very hazardous to breath and causes cancer.
A large concern with Aerospace and Aviation is the production of Hexavalent Chromium which can be generated by the welding of Stainless Steel parts or could be found in the painting of Aerospace parts where the paints have Chromate in them. When you work on these parts such as grinding or sanding you are exposed to Hexavalent Chromium which is very hazardous.
- HazDust — Grinding and Buffing of Flammable Metals, aluminum, titanium
- APB Downdraft — Grinding and Buffing of non-flammable dust such as steel
- SPC — welding of small parts
- VCF & HCF — welding of larger parts
- PBM — Grinding and polishing of large parts
- Mist and Smoke Collectors — CNC Wet Machining
- PFC and Portable Fume Booth — Odor and vapor
