Floor drains that do not have water flow through them will go dry and sewer gas will leak out of them because the trap makes a seal and stops air from flowing out of the floor drain. Most commercial properties have drip primers that allow water to drip into a floor drain and keep the trap sealed but because water is dirty and since the drip primer has to have such a tiny hole, over time the drip primer corrodes and stops working and stops keeping water filled in the trap which is below any floor drain. When this happens like 2 - 4 yrs after the building was constructed the owner (like most) don't care or even know to care where the drip primer is. The best way I believe to seal a floor drain trap that is hardly used is to pour 1 gallon of water then 1/2 cup of vegetable oil down the floor drain, this oil sits on top of the water constantly making a seal on top of the water so the water can not evaporate and always making a trap seal.
