- Turn off the supply at the isolating valve on the oil tank.
- Mop up spills with sand, earth, cloths or any absorbent material.
- If the leak is in the oil tank – try to collect as much as possible into cans, buckets etc.
- If the leak is severe, try to form a dam with sand or earth until help arrives.
- Phone the Fire Brigade if you cannot cope and pollution of a watercourse is possible.
- Phone your installer or your oil supply company to get the tank pumped out.
