Typically tucked away in a police officer’s holster, Taser guns have the power to bring criminals crashing to their knees. Once triggered, these weapons deliver 1,200 volts of electricity to the body of a target typically for five seconds.

It’s vital that anyone who works with or around hazardous materials can properly identify the various aspects of each hazmat placard, as well as the various classifications that each one represents.

In all, carriers must display at least four placards in areas where the view isn’t obstructed. Some carriers add extra signs on each side of the truck cab for additional visibility.

With rare exceptions, companies that transport hazardous materials without the use of DOT hazmat placards are at risk for stiff fines and other penalties.

What is hazard Class 2.2 shipping requirements

Have you ever seen a truck, railcar, container or large tanks at a tank farm and wondered what types of chemicals it was transporting or storing? The answer can be found in its UN numbers and hazmat placards.

In addition to a UN number, the DOT requires cargo to carry Hazmat placards that help shippers determine its class, division, and compatibility group.

The suspect is first met by the laser guide, which can reach a distance of about 7.6 metres. Once positioned, the officer can pull the trigger and deliver a shocking shot. Bursting from the gun’s cartridge, two needle-style probes propel through the air to pierce the target’s skin. Electricity then flows from the gun through insulated wires to ultimately hijack the nervous system of the unfortunate victim.

Also known as ‘electro-muscular disruption’ guns, this method of defence results in the suspect’s muscles contracting, temporarily paralysing them as they fall to the ground.

According to federal regulations, each freight container, railcar, transport vehicle, or other vessel carrying hazardous materials must display placards on each side and each end. Regulations also state that placards on railcars and transport vehicles must be clearly visible from the direction they face unless they are obscured when coupled with another railcar or transport vehicle.

Similar to road or construction signs, these diamond-shaped hazmat placards alert the public that potentially hazardous materials are being hauled, as well as inform emergency responders which chemicals are present in case of an accident. Even if members of the public or first responders are unaware of exactly which materials are on board, the presence of hazmat placards lets them know that they should proceed with caution.

These numbers are assigned by the United Nations (UN) Committee of Experts on the Transport of Dangerous Goods, and must be listed on the Material Safety Data Sheet (MSDS) of each shipment. (Goods that aren’t classified or regulated by the UN are given four-digit North American (NA) numbers ranging from 8000-9279. These numbers are designated by the United States Department of Transportation (DOT).)

Hazmat warning placards are broken down into nine different classifications, along with their divisions. Each class number is found at the bottom of the sign, while the division number can be found in the middle.

Located on the back or sides of trailers or other containers, UN numbers (or UN IDs) are four-digit numbers ranging from 0004-3534 that identify dangerous goods or hazardous substances — such as explosives, flammable liquids, or toxic substances — in the framework of international transport.
