FAQ: class 4.3 labels

What does the blue background mean?

It designates class 4.3 substances, which emit flammable gases in contact with water. Keep the package dry. Trained responders must select the extinguishing agent from the SDS and the UN-specific ERG guide.

What is the difference between this label and a placard?

The 4 X 4 in label identifies the package. The larger placard is displayed on the vehicle or the large means of containment. Depending on the quantity carried, both may be required.

Paper or synthetic: which should I choose?

The water-resistant paper is intended for indoor use. PVC-free synthetic suits indoor and outdoor use, for packages exposed to the weather.

How many labels are on a roll?

500 labels of 4 X 4 in (10.16 X 10.16 cm), in paper as in synthetic.

Do the labels comply with the TDG Regulations?

According to the manufacturer, yes. Always check the requirements that apply to your shipment.

Suggestions for shipping class 4.3 substances

Need complementary safety equipment for handling closed packages? Consider the glasses (YASF201) with clear SecureFit anti-fog lenses, the gloves (GNTFC) with nitrile coating for handling, the toecaps (VC8021) for TurboToe toe protection, the helmet (TA80) for V-Gard top-of-head protection, and the vest (V6935) with mesh back for visibility. Select PPE through the risk assessment, not from the hazard class alone.

Under “Accessories” at the bottom of the page. Looking for complementary equipment? Consider the tape (ECT3YE1) with yellow CAUTION wording for marking from a safe area, the removable reflectors (EPTR) for marking a stopped vehicle, and the road safety kit (TR16) to complete vehicle supplies.These suggestions are not a response equipment list for a leak.
