Discussion on whether flammable gas detectors are needed in hazardous waste warehouses?
Thread Content
A hazardous waste warehouse stores used activated carbon, as well as waste containers from various solvents after they have been used; nothing else is there. Such common hazardous wastes are likely to emit some organic compounds – is it necessary to install gas detectors? If setting it is necessary, given the sheer number of organic gases emitted, how should it be set? I originally installed VOCs sensors and linked them to the emergency fans in the warehouse; however, experts believe that it is not possible to use VOCs sensors for such interlocking purposes. The key point now is whether combustible gas detectors need to be installed in this situation.
From a safety perspective, the spent activated carbon and various solvents stored in hazardous waste warehouses are bound to emit some organic compounds, which may lead to the accumulation of flammable gases. Therefore, it is recommended to install combustible gas detectors in hazardous waste warehouses to monitor the concentration of combustible gases in real time, thereby enabling timely measures to prevent fires and explosions. To address the issue of \"there being too many types of organic gases emitted,\" one could consider using gas sensors that are sensitive to common organic compounds, such as formaldehyde and benzene. If it is not possible to determine the specific type of organic compound, a multi-parameter probe can be used, one that is capable of detecting both flammable gases and toxic gases, in order to improve the accuracy of monitoring. As for the issue of whether VOC sensors cannot be interlocked, adjustments can be made based on the specific circumstances, or professional engineers can be sought to help resolve it. -
You can consult the manufacturers of combustible gas detectors.
To make the settings, if there are too many types of gases, it is possible to find the explosion limit for each one; priority should be given to installing detectors for those gases that are more prone to exploding
I casually asked a certain manufacturer, and they have VOC detectors that can interlock with the emergency fans.
Thank you for your feedback. Indeed, there are some VOC detectors that can interlock with emergency fans. This allows the emergency fans to be automatically activated for ventilation when the concentration of hazardous gases exceeds a certain threshold, thereby preventing accidents. However, it should be noted that there may be differences between different detectors and fan devices. Therefore, before installation, it is necessary to verify the compatibility of the devices and conduct relevant tests to ensure their reliability and stability. Professional engineers' guidance and assistance are also needed to ensure the proper use and maintenance of the equipment. -
Will the volatile organic compounds reach an alarm level?
The VOC detector interlocks with the emergency fan, which can be activated automatically to provide ventilation when the concentration of hazardous gases exceeds the threshold, thereby preventing accidents. This is still necessary
It’s not necessary to install combustible gas detectors; generally, hazardous waste warehouses are equipped with forced ventilation systems.
The newly built hazardous waste storage facility at our company is equipped with combustible gas alarms. We chose a methane detector based on the types and concentrations of the waste liquids present there. In reality, this type of combustible gas detector can detect several different gases.
