MAINTAINING YOUR CABINET
5.1 MAINTENANCE SCHEDULE
COSHH regulations from the UK Health & Safety Executive (HSE) require that equipment to control
exposure is properly maintained. It must be thoroughly examined and tested every fourteen (14) months
and records kept of this. This 14-monthly period specified suggests annual maintenance with two months
grace which is equivalent to Esco annual maintenance schedule.
In view of this, proper and timely maintenance is crucial for trouble free functioning of any device and
your Esco cabinet is no exception to this rule. We strongly recommend that you follow the maintenance
schedule suggested hereunder in order to obtain optimal performance from your Esco cabinet.
