It is never a good idea to allow corrosive chemicals or hydrocarbons to leak from their containment vessel. This is particularly true in a commercial building or institutional facility where customers, guests, patients, and other individuals not familiar
with these materials have the potential to come into contact with them. This is a safety issue first and a liability issue second. However, elevator pits represent an additional and different type of safety threat. Should hydraulic oil leak into an elevator
pit from an elevator hydraulic system and then the building become involved in a fire, the hydraulic oil could have an impact on the speed with which the fire can be controlled. If equipment located in an elevator pit develops a hydraulic oil leak, a
layer of hydraulic oil will build on the pit floor. When firemen then put water on a fire, the water finds its way to the bottom of the pit and the oil floats on top. When the pit is full, additional water making its way into the pit pushes the oil out at
the top. When the oil leaves the confinement of the pit, it begins to spread. At this point, adding more water only spreads a high-grade fuel into the fire. Water is no longer a suitable tool for fighting the fire.
Multiple Elevator Pits
When multiple elevator pits need to be monitored we have a variety of options including a multi zone alarm panel with both visual and audible alarms and normally–open / normally–closed relay outputs. Systems can detect the presence of both hydraulic oil
and water separately on the same or independent zones. This is achieved by using the TraceTek sensing cables. The presence of either liquid causes a leak alarm, which alerts an operator or control system.
Single Elevator Pit
For single elevator pits, a popular option is a single zone alarm again with both visual and audible alarms and normally–open / normally–closed relay outputs. Systems can detect the presence of both hydraulic oil and water separately on the same zone.
This is achieved by using the TraceTek sensing cables. The presence of either liquid causes a leak alarm, which alerts an operator or control.
