The new Zistos SafeAirLADDER, patent pending, integrates gas metering electronics and alarms onto a ladder that is used to facilitate entry into a confined space.
The gas metering sensor is mounted to the base of the ladder and is designed to be inserted into a confined space, such as a tanker truck, rail tanker or processing tank. The top of the ladder mounts onto the manway and has an integrated alarm console, which remains outside of the space. The console offers a visual and audible indication of atmospheric conditions as communicated from the metering sensor at the base of the ladder.
When activated and inserted into a confined space, the ladder can alert a worker — and their manager — prior to entry that the atmosphere inside of the tank is not safe. Conditions are indicated via a yellow light (indeterminate state or malfunction), green light (safe environment) or red light (hazardous environment) in conjunction with a loud 120 decibel alarm. These visual and audible indicators provide local alarms for the worker and will alert them to a hazardous condition. Management can remotely monitor the status of all ladders inserted into confined spaces via WiFi on a smartphone, tablet or computer.
