Can a bathroom be installed within the plant area?

I’m not sure what regulations specify this, but for the convenience of employees, it is possible to build a toilet in a location far away from the equipment area; this can be considered as ensuring a distance of 30 meters between such facilities and the equipment

I really haven’t seen any device that comes with a bathroom

Who said there isn’t? They are generally found in the plant area operation rooms, control rooms, and offices.

I don’t think it’s necessary to look for rules for everything. What if a bathroom is installed in the plant area, and someone can’t resist smoking there, resulting in a fire or explosion? Such accidents are not without precedent.

That makes sense. However, for a device 100 meters long and wide, if a toilet is to be built, taking safety distances into account, roughly 1/4 of that area needs to be set aside. If we really agree to do this, it will seem like a huge joke in the history of chemistry.

Next to the DCS cabinet room in the blast-resistant structure, there is usually an on-site operation room, and a restroom is certainly designed as well. There’s no need to design it on-site; safety issues are difficult to address.

The operation center of the facility definitely has a toilet, but it is located at some distance. Personally, I think it would be fine to build a toilet near the green belt beside the facility. As long as there is sufficient safety distance, that’s enough. Inside the device, hehe!

Sampling is done wherever there are toilets, hehe;P

Most of the older installations from the past had toilets, not only for use by their own employees but also for those who carried out maintenance work. In recent years, new installations generally do not have separate toilets outside; instead, toilets are only provided in the cabinet rooms or near the control rooms. Personally, I think this is not very user-friendly. When hundreds of people are working on maintenance or upgrades, finding a place to use the toilet becomes a difficult problem to solve.

I have consulted experts from the Chemical Industry Institute and those responsible for standard-setting at SEI, and I have also referred to GB50984. Based on all this, my recommendations are as follows: First, it is necessary to consider whether bathrooms can be located in the equipment area, as people may be there, and in the event of a fire, explosion, or release of toxic gases, it could lead to casualties. GB50984, GB50016, and GB50160 are the standards that specify such spacing. Among them, GB50984 is comprehensive. Second, the explanatory notes of GB50984 contain a schedule. For determining fire separation distances, refer to GB50160; for explosions, consider VCE highly explosive sources (light hydrocarbons, over 10 tons); for toxicity, consider highly toxic sources. This standard essentially specifies the distance between populated areas and sources of hazard. Third, the situation in the restroom is rather complex; there are people there, but certainly fewer than in areas such as the outdoor exercise room. But precisely because people are taken into account, major facilities generally refer to the card spacing specified in GB50984. Since this standard does not explicitly designate the bathroom as a separate category, in practice bathrooms are generally not placed in the equipment area. However, if it is necessary to locate a bathroom in that area, it does not violate the standards; it is only important to place it as close as possible to the edges of the equipment area, away from sources of high fire, explosion, or toxicity hazards, and in a location where evacuation is easy. Additionally, measures such as proper ventilation and fire prevention should be implemented. Otherwise, it is preferable to integrate the bathroom with other facilities such as an explosion-proof control room, or to locate it far away from the production area and closer to the living areas.
