Safety Aspects
VRU is installed in environment containing combustible liquids and explosive gases.
Risks of fire and explosion with toxic emissions
Preventive measures and risk analysis have to be performed:
HAZOP
ATEX explosion protection document (EXDOC)
SIL safety integrity level risk assessment
EC declaration of conformity for the whole unit (§ 3.7.1.1)
Manufacturer assumes responsibility for compliance with the directive
Manufacturer should provide a conformity assessment of the whole assembly
Manufacturer provides clear instructions for assembly / installation / operation / maintenance… in the operating manual.
Some of the VRU safety features:
The whole system is explosion pressure proof to 9 bar
All valves with open / closed limit switches
Gasoline pumps installed below liquid level
High and low level switches on the re-absorber column
Temperature monitoring in the activated carbon beds
Outlet temperature of the vacuum pumps < 50°C
Detonation arrestor in the inlet
Two positive closing valves in each gasoline circulation line
Etc
