Elevator Pit Application
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 Pit
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
or the AquiTron™ probes. The presence of either
liquid causes a leak alarm, which alerts an operator
or control system.
Single 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 or the AquiTron™ probes.
