TECHNICAL

Tank Sizing and Siting

Tank Sizing

Factors affecting tank sizing:

• Physical constraints imposed by the site.
• The estimated off-take capacity at peak demand.
• The required frequency of delivery.
• The access for deliveries

Tank Siting
A Calor specialist will always advise on the most suitable siting for Calor storage,
however there are some specific requirements that must be considered

General Safety Measures

• Ready access to a water supply for all installations.
• 19mm hose reel where the storage capacity exceeds 2500 litres.
• (Two nominal 9kg dry powder extinguishers where capacity does not exceed 2500 litres.)
• Crash protection where risk of damage by road vehicles.

Overhead Power Cables

• No overhead power cable to pass over the area contained within a distance measured 1.5m horizontally from the shell of the tank.
• Where the voltage in the cables exceeds 1.0kV, the distance from the power line must be increased to 7.5metres.

Testing Equipment

• Equipment installed by Calor normally remains the property of Calor and as such is subject to periodic examination.
• Where Calor does not own the equipment, an inspection service can be provided to insure the integrity of the system.

Access

• Calor must retain access to the land the tanks are sited on for refuelling and maintenance.
• Over access roads to the storage compound and the gas mains in metered developments.
• The access road for tank and subsequent fuel deliveries must allow the Calor tanker to get within 25m of the inlet valve and be sited so the driver can see the vehicle during the refilling process.
