How to store liquid fertilizers

How to store liquid fertilizers?Various types of fertilizers are used on green houses in horticulture. In most cases, part of these fertilizers used contain hazardous substances. The storage of these hazardoussubstances is an important consideration, because the unsafe handling of these substances can lead to health problems, personal injury or even explosions. Not every company is aware of this and often not enough attention is paid to the correct way of storing hazardous substances. Recently, a number of changes have been made regarding legislation of liquid fertilizers. As a result, other issues become points of attention. Therefore, we have listed the most important ones for you.

Drip tray

Liquid fertilizers are stored in a dedicated storage area. For any form of liquid fertilizer larger than 50 litres, it is important that the storage facility is equipped with a drip tray or liquid-retaining floor, so that leaked or spilled hazardous substances cannot escape. The PGS 15 regulations contain the following information on this subject:

“If the working stock consists of a quantity of more than 50L, the products must be placed above a dripping tray or a facility like this. This can be deviated from, if (the relevant part of) the floor of the production/workspace in question is at least liquid-retaining.”

Separate storage for hazardous substances

Some fluid fertilizers may react with each other, causing dangerous gases, heat generation or precipitation, among other things. To prevent this, substances that can react with each other should be stored separately. Here you can see how different substances react with each other and what you can do to prevent this. To prevent liquid fertilizers from being unloaded in the wrong pipes, you can have unloading points fitted with slot spanners. Watch the video below for more information.

Lockable door

For extra security you can choose to provide the storage areas with a lockable door. This will prevent unauthorized persons from entering the storage room. Please note that the storage space must be openable from the inside without the need for a key.

Warning Signals

Make sure that the company’s storage location of the fluid fertilizers is well indicated with warning signals. These must indicate the hazards of the stored substances. The "Fire, open flame and smoking prohibited" sign must also be present in all storage facilities. When storing and unloading liquid fertilizers, stickers with CLP icons must also be placed on the pipes and barrels.

In case of emergency

If, despite the measures taken, something does go wrong, it must be possible to take immediate action in the event of an emergency. Therefore, make sure that there is a fire extinguisher of at least 6 kg near each storage area. It is also strongly recommended to equip a company with an eye shower
