No firefighter in their right mind is going to knowingly pump a drop of water anywhere near or in the direction of a data center, let alone into it. That's why they're equipped with Halon or other oxygen displacement, cooling, and flame suppression systems, and the FDs are equipped with appropriate Class 2 (Electrical) firefighting equipment. FDs conduct periodic inspections of all on-site fire-fighting equipment and the local station shifts do walk-throughs to review their procedures. If any hazardous materials are present (guaranteed in a DC), they're also taken into account.
The FDs that serve industrial sites are equipped to fight fires where the fuels can range from paper through plastics, up to actual petrochemical fuels. I worked in the last semiconductor fab still operating in Silicon Valley and worked with the City of Santa Clara FD on their plans, which had to deal with the presence of extreme toxins and corrosives such as hydrofluoric acid used to etch silicon wafers. They used to be responsible for the Intel fab next door until it was shut down and the fab in Hillsboro, OR, took over all R&D production. They said it was a nightmare waiting to happen because of the volume of extremely hazardous chemicals used on-site. Someone should be sued and go to prison for signing off on permits that would allow water to get anywhere near a DC - it's a violation of the National Electric Code, for starters. If anyone sees something like that, it should be reported immediately, and not within the organization, since the facilities people are either incompetent or complicit in keeping quiet about it. That's what anonymous.hotlines are for, and the media, if no action occurs with the hotlines - we're talking about the possibility of serious injury and death here.
