EROS Easy Riser – Brings Pre-Vac
Valve Maintenance Down To Earth
In line with Work at Height Regulations,
EROS Easy Riser demonstrates our continuing
commitment to product development
The EROS Easy Riser is a system designed to eliminate
working at height. Bulk fuel storage tanks need to breathe
during the fuel delivery process. The vent or ‘breather’
pipes vent at a high level, typically around the 4-5 metres
height. Tank breather vents are fitted either with weather
caps or pressure vacuum valves.
Pressure vacuum valves are required on all sites with
Stage 1 vapour recovery systems. The pressure vacuum
(PV) valve allows a slight build up of pressure vapour in
the tank farm and greatly reduces the free flow of volatile
organic compounds to atmosphere. Many countries
around the world have signed up to this type of system on
the basis of environmental pollution control.
These PV valves are a mechanical moving component and
as such require regular inspection and servicing to prevent
blockages and ensure functionality. The traditional method
of inspecting or changing these units would be to use a
ladder, scaffold tower or some form of mechanised lifting
gear to get an operator to the top of the vent to do this
work. Working at height can be extremely dangerous and
following the ‘working at height’ legislation that came into
effect in 2004 it became clear that an alternative method to
inspect the PV valves was needed.
