Method of despatch - outside of London
Samples of petrol, benzole, kerosene and other “dangerous goods” (defined as products with a flashpoint below 66ºc) must not be sent through the post. Such goods must have affixed to the external package a label stating the contents and conspicuously bearing the word “Flammable”. Samples of these products are to be forwarded by train.
The official packaging is designed to comply with the railway regulations for the conveyance of flammable liquids. If satisfied that the samples have been properly packed to conform with the regulations, the Officer may sign the consignment note.
Samples of oil other than “dangerous goods” may be forwarded by the cheapest means. They should not be marked “Flammable”.
Method of despatch in London
In London, samples (packed in wooden boxes) are to be conveyed by messenger or carrier. If the boxes are numerous, they are to be enclosed in unsealed wooden cases. “Dangerous goods” are to be labelled “Flammable”.
Letter of advice (test note)
A test note is to be sent separately to LGC on the day the sample is despatched. Form C&E 140 is to be used for all samples, except those taken by RFTU’s for which form C&E 140RF is to be used.
For samples of Gas Oil or Kerosene to check for colour marker, commercial dye or other additive, the test note is to be in duplicate and must relate only to one sample. The duplicate copy will enable LGC to advise the despatching Officer of the result of the test, as LGC retains the original test note.
Samples requiring priority test by LGC
Only samples for which priority treatment is essential are to be marked “URGENT”. Both the sample and test note are to be marked accordingly, and a special note is to be made in station records of all such samples.
On receipt of a test note or sample marked “URGENT” LGC will contact the Officer if the associated sample or test note has not been received within 2 or 3 days.
