Packaged Goods
'Packaged goods' covers any method of transportation other than tankers, tanks, tank containers and bulk (that is, unpackaged solids in bulk). 'Packaged goods' includes drums, bags, boxes, cylinders, bottles, and Intermediate Bulk Containers (IBCs) .
More than 90% of HazChem incidents involve packaged goods rather than goods in tanks.
All dangerous goods are allocated a transport category ranging from 0 to 4. These values are used to determine whether the total quantity of goods carried is sufficiently large to fall within the regulations. Transport Category 0 relates to certain highly dangerous infectious substances. Transport Category 1 represents the most dangerous products, such as toxic compressed gases. Transport Category 3 represents less dangerous substances, while TC4 is deemed so safe that most of the regulations do not apply.
Gases are assigned a transport category relevant to their risk, i.e.:
|
TC 1 TC 2 TC 3 |
Toxic Flammable Non-Flammable, Non-Toxic Compressed Gas |
When determining whether the regulations apply for loads of the same transport category, the total quantity in litres or kilograms must exceed the threshold for the relevant transport category. All containers, drums etc count, and it is the weight or volume of container that counts - it is immaterial whether it is full or nominally empty (although cleaned purged containers are disregarded). No differentiation is made between litres volume and kilograms mass.

If the load is of mixed transport categories, the total for each transport category is multiplied by the relevant multiplier below. The result for each TC is added. The threshold is 1000 - if the total exceeds 1000 the regulations apply.

This is not as complicated as it sounds!
I have created a form that can act as an original note and lead you through the calculations. Click
here to download the form in Microsoft Word format, or right-click on the picture at the bottom of the page to save as a jpeg.Example:
7.5-tonne vehicle carrying 10 1KG tins of a substance in TC-1, 4 25 litre drums of a substance in TC 2, and 6 50KG sacks o a substance in TC 3.
TC1 10 x 1KG = 10 KG x TC1 multiplier [50] = 500
TC2 4 x 25 l = 100 l x TC2 multiplier [3] = 300
TC3 6 x 50KG = 300 KG x TC3 multiplier [1] = 300
Total 500+300+300 = 1100 which exceeds the 1000 threshold, so regulations apply.
Two new Transport Categories, 1A and 2A, have been introduced for certain class 1 explosives. Their thresholds and load multipliers are shown below.

Special Provisions (Parking and Supervision Rules)
To ascertain when these rules apply we need to look at Column 19 of Table A of Chapter 3.2 of ADR. This column gives a reference to Chapter 8.5 of ADR and indicates what special provisions apply to the parking and supervision rules for a particular substance and any other special requirements.
If the total mass of substance limits are reached then the parking and supervision rules apply.
The tunnel book (below), available from British Toll Tunnels, remains a useful reference source.
