Tips for safe usage of IBCs in the summer

The summer is coming! A sunny time with pleasant temperatures – the temperature is gradually rising. Please be advised this can also affect the pressure build-up in IBCs. Therefore, we would like to give you some tips about the optimal and safe usage of the VARIBOX IBCs (Intermediate Bulk Containers). 

IBCs in the summer

UV resistance of the VARIBOX

Exposure to sunlight will lead to weathering of materials. UV radiation has a negative effect on the properties of materials. It can also change the color pigments in materials leading to fading of colors. The VARIBOX is manufactured from materials that have built-in protection against the effects of UV radiation. This lengthens the lifetime of our product, so you can truly reuse the VARIBOX containers even in sunny countries.

If the IBCs get too warm, pressure can build-up

Overpressure in the VARIBOX can also occur as a result of a rise in temperature. If a VARIBOX is used without a pressure relief vent, we recommend protection against high temperatures. To avoid the air in the VARIBOX heating up, it must be protected from direct sunlight when stored outdoors.

Overpressure can be recognized by a bulging of the upper part of the VARIBOX. The VARIBOX has been designed to cope with higher pressures, so don’t worry about its integrity. But relieve the overpressure before you connect the VARIBOX. This can be done by turning the screwcap by 30°. In this way, sudden pressure relief and leakage of the contents are avoided. Make sure that suitable personal protective equipment is worn!

Due to the bulging, the VARIBOX Safeline system may be raised and may not function as desired. After the pressure has been relieved, the position of the Safeline system must be checked, appropriate personal protective equipment must be worn.
