It was heavy, dirty work in some of the departments. In the press shop, for instance, grenades were oiled with graphite mixed with oil. Fortunately, employees could clean themselves up, to some extent, in one of the washrooms on site.

Building 277 – Transformer house – Hembrug
This was one of the transformer houses which supplied some of the site with steam, helping to make the business self-sufficient. Buildings where there was a risk of explosion didn't have an electricity supply, but instead used steam from the boiler house. A secure electrical system was later added. Hembrug had its own medium-voltage network (3000 to 10,000 volts).

This cartridge store had its own small turning shop for the production of percussion caps. Legend has it that the archives of the German occupying forces were kept here during the war. Later on, it housed Eurometaal’s water purification equipment.

Store – Building 85 – Hembrug
This was the store for the munitions assembly department (MSLW). Things like machine components, spraying moulds, and casting moulds were kept here.
