Editing Herculus Bull (section)

== Snubable Enterprise ==
Swiss engineer [[Stefan Shrankenhaus]] approached Bull through industrial engineering contacts and offered him a much higher salary at Snubable Enterprise. Bull interviewed with [[Lucian Pușcaș]] and joined the thermal section at the company's main complex in [[Căciulați]], [[Moara Vlăsiei]], on 4 March 2013. Pușcaș had designed the plant's primary–secondary chilled-water arrangement in 2010.<ref name="thermal"/> Bull began by inspecting secondary cooling circuits and checking the condition of their pumps. Within weeks, he challenged Pușcaș's inspection methods and received a reprimand. He complied with the existing procedures and was allowed to investigate minor equipment faults by that summer.

In 2014, Bull traced overheating in a refrigeration equipment room to a faulty ventilation damper and arranged for its repair. The next year, he worked on additional cooling circuits for the reinforced lower technical section built during Snubable's November 2015 expansion. He revised technical drawings and helped commission the new circuits. Bull continued to disagree with Pușcaș about proposed changes. In 2016, he complained to Shrankenhaus, who heard him out but declined to intervene in the thermal section.

Pușcaș died on 17 February 2017.<ref name="pușcaș"/> [[Richard Rambam]] appointed Bull to replace him as Lead Thermal Engineer. Snubable told its employees that Pușcaș had died from a cardiac problem after drinking. In fact, [[Dr. Arnold Isaak Burgelstein]] had killed him with a cyanide injection. Bull noticed unusual restrictions around Pușcaș's office and questioned the explanation for his death. Rambam told him to stop asking. Bull didn't know that Burgelstein had committed the killing.

Bull changed how the technicians worked after taking over. He assigned individual workers to look after particular cooling circuits and required them to document repairs. Unlike Pușcaș, he let technicians finish routine maintenance without repeatedly taking their work apart. He continued checking major alterations himself. In 2018, Rambam wanted to connect more incubators to an existing chilled-water circuit. Bull refused to approve the work until the available water flow had been tested. Rambam accepted the delay.
