2.7.1 Transportation Boxes All samples of hazardous materials must be transported in an approved transportation box, which will be provided to you. These approved boxes have a performance package rating.
You can also use an actual ullage if you have taken one. To calculate how far you must lower your sampling equipment, you will need to make the following three calculations: Upper Sample: Ullage plus one sixth (1/ 6) of the innage Middle sample: Ullage plus one half (½) of the innage Lower sample: Ullage plus five sixths (5 / 6) of the innage From a practical point of view, it is acceptable to work to the nearest inch. Also, you will probably find that the calculations are easier if you convert feet and inches' measurements to decimal feet. For example, use 27.5' rather than 27' 6".
These labels should be pre-printed and contain the necessary components of a GHS complaint label.
2.6 Sealing Samples Samples placed onboard a vessel for delivery to the cargo receivers, those left in the custody of other persons, and retention samples are usually sealed to prevent tampering. Seals should have a company name or logo and a unique number embossed into the surface. SGS seals must not be given to non SGS employees, for any reason. They are to be kept in a secure location when not being used. 2.7 Sample Transportation All samples transported on a public highway must be transported in accordance with national and local transportation regulations. These rules are intended to protect the life of the driver and other users of the public highway, in addition to providing invaluable information to emergency responders, along with the applicable Safety Data Sheet and Emergency Response Guide which should be consulted.
2.8 Calculation of Upper, Middle & Lower Spot Sample Ullages When sampling shore tanks, and to a lesser extent marine vessel tanks, the most common type of samples taken are those of upper, middle and lower. It is therefore important for you, the Inspector, to be able to calculate how far into the tank you must lower your sampling device in order to take these samples at the correct level. The first two pieces of information that you must obtain are the reference height of the tank and the depth, innage, of the liquid. By subtracting the innage from the reference height you will get the ullage.
