@ maroush: Ahan, nice to know someone else here related to the pharma industry. Yup ur right, u can't take pictures on site. Not even with ur mobile phone. There is a serious risk of causing an explosion. (camera battery or mobile battery may react with the flammable atmosphere)
If for some reason u do need to take a picture of something then u need to get a special permit from the manager and they give you a special security camera. And the team leaders of the manufacturing technicians on the plant are also given special mobile phones in protective casing etc.
I needed to take pictures for my internship report. I had to prepare a report at the end of the internship so I got the special permit from the manager, he gave me the security camera and thats how I took these pictures.
