What is meant by a screw fitting for tank filling being in “good condition”?
The regulations do not define “good condition”. However we think it is sensible to consider whether a fitting is fit for purpose in the broadest sense. You should make sure the screw thread is usable and that deliveries to the tank using the fitting can be made safely and securely. Using the screw fitting should not increase the risk of oil spillage or jeopardise operator health and safety, for example from working at height. You should discuss the suitability of the tank’s screw fitting with your oil delivery company.
