What does “active storage” mean and how is it different from “passive storage”?
Passive storage is the storage of flammable liquids in containers that are securely sealed and that are not filled or disposed of in the store or opened for any other purposes.
Active storage is the storage of flammable liquids in non-stationary vessels that are used at their storage location as stationary removal or collection containers or opened for other purposes.
Does a safety storage cabinet need to be operated with an industrial exhaust system?
If filling or transfer is carried out on the safety storage cabinet (= active storage), operation without an industrial exhaust system is not permissible. For storage of sealed containers (passive storage), operation without an industrial exhaust system is permitted provided the following requirements for the containers to be stored are satisfied:
This must be documented in the explosion protection document, and the resulting ex-zones around the safety storage cabinet must be maintained:
For passive storage, operation with an industrial exhaust system with a minimum of 10-fold continuous air exchange per hour is therefore advisable. In this case, no ex-zones are assigned to the cabinet.
What rate of air exchange must the safety storage cabinet be operated with?
The air exchange rate is specified by the operator as part of the risk assessment for the workplace. Generally accepted values can be used as the basis for determining the rate:
For passive storage of flammable liquids, at least a 10-fold air exchange per hour is recommended to avoid the formation of an ex-zone. A higher rate of air exchange may be necessary to reduce odours.
For active storage of flammable liquids, the safety storage cabinet must be operated with an air exchange rate of at least 21 m³/h and the ventilation function must be monitored.
Flammable gases should be stored with at least a 10-fold air exchange per hour, and toxic gases with at least a 120-fold air exchange per hour.
Does a safety storage cabinet need to be connected to an earthing system?
Safety storage cabinets without industrial ventilation and safety storage cabinets for active storage must be earthed by equipotential bonding to avoid ignition hazards.
