Working in the contamination control industry, we are used to working directly with Pharma companies, Healthcare companies, labs, controlled environments and drug processing facilities.
When ‘controlled environments’ are discussed, for most people a Hazmat suit and air looks will spring to mind; brightly lit facilities with strict SOPs and rigorous cleaning schedules to stop the pollution of sensitive products.
So it may come as a surprise to many that auto manufacture facilities can also be classed as controlled environments, and that the same SOPs that apply to clinical trials or drug processing are often applied to building and spraying cars.
There are two main contaminant factors at play in vehicle manufacture:
Firstly, particulate contamination – such as dust and debris reaching the spray painting area and areas where parts are prepared for painting.
When a consumer spends thousands of pounds on a brand new car, the finished result is expected to be perfect. Dust and particles getting into the paintwork may not only damage the aesthetics, but can also cause gaps in the paintwork which would eventually lead to water reaching the chassis/body underneath and rusting to take place. Great lengths are gone to by auto manufacture companies to make sure that these pollutants, which are often air bound or are bought in on the feet and wheels of employees/trolleys, can be removed from the environment in much the same way as a laboratory or other sterile zone. You can see an example of SAAB, a major player in the auto manufacture industry, using a floor level solution to reduce air borne contaminates here.
The second issue is electrostatic discharge, a problem that has been prevalent in the technology industry, as the development of electrical items has rendered them more prone to damage by electro-static. If you want to find out about ESD in detail, please check out our other blog post here, which is a comprehensive overview of ESD in electronics manufacturing.
Electrostatic can cause issues with car electronics in the same ways as for the manufacture of mobile phones, computers, radios and more. Check out our Continental case study here, and see how we have helped global brands to combat ESD.

Electrostatic discharge (ESD) is caused by a number of factors and is commonly generated by the contact of materials. It can be produced by everyday occurrences, such as a person picking up a piece of polystyrene packaging or walking across a carpet; it can even be caused by dust in the environment.Positive and negative charges are stored in materials and carried by people. The human body is capable of storing a charge up to 25,000V. This charge is then dissipated (Electrostatic discharge) through the receiving object as the current seeks an unimpeded path. An object’s metal chassis will often act as the conductor for the static to strike, but it can occur through other materials.
