Throw Back to Basics: Hazmat Placards

By Brian Zaitz

在道路上上下行驶，您几乎可以肯定会通过标语牌或带有标语牌的建筑物开车穿过车辆。这些识别标记对于我们作为第一响应者的关键是适当反应和减轻hazmatincident.

The NFPA 704 placard is a four-color placard used to identify a hazard using a 1-4 scale to identify the health risks noted in the blue; flammability noted in red; reactivity noted in yellow; and white to make denote such as no water or other special hazards. The key is to both identify the risk as well as preplan the facility.

The DOT placard is commonly found on shipments traveling across the country everyday. The DOT categorizes hazardous materials into nine hazard classes (Explosives, Gases, Flammable Liquids, Flammable Solids, Oxidizers, Poisons, Radioactive Materials, Corrosives and other Miscellaneous). These classifications are noted with a number 1-9. In addition, the placard is colored and a symbol placed to assist in the hazard identification of the hazard.

It is important to review and familiarize with the placard system; knowing the nine hazard classes and how to respond will both improve ourfirefighters‘ overall scene safety and efficiency for mitigation.
