Describe occupancies that may contain HM’s
Not confined to chemical facilities or Nuclear power plants – HM’s are stored in warehouses, hospitals, laboratories, industrial occupancies, residential garages, bowling alleys, home improvement centers, garden supply stores, restaurants, and other facilities and businesses… they can occur almost anywhere
Describe how your senses can be used to detect the presence of HM’s
Visual, auditory, or olfactory clues
Describe specific containers and container shapes that might indicate HM’s
many different types of containers, ranging from 1-gallon glass containers to 5000-gallon steel storage tanks. Steel or polyethylene plastic drums, bags, high-pressure gas cylinders, railroad tank cars, plastic buckets, above ground and underground storage tanks, truck tankers, and pipelines are all types of containers used with HM’s. Some very recognizable chemical containers, such as 55-gallon drums and compressed gas cylinders, can be found in almost every commercial building, materials in cardboard drums are usually in solid form. Stainless steel containers hold particularly dangerous chemicals, and cold liquids are kept in thermos-like Dewar Containers. One way to distinguish containers is to divide them into two separate categories: bulk storage containers and non-bulk storage vessels
Describe tanks that could hold HM’s
Fixed tanks [Secondary containment, AST’s & UST’s]; large transportation tankers, totes [portable plastic tanks surrounded by a stainless steel web that adds structural stability and protection], and intermodal tanks [both shipping and storage, surrounded by, or part of, a boxlike steel framework for shipping.

Yellow Section: chemicals in this section are listed numerically by their four-digit UN identification number. Blue Section: Chemicals in the blue section are listed alphabetically by name. The entry will include the emergency action guide number and the identification number. Orange Section: This section contains the emergency action guides. Guide numbers are organized by general hazard class and indicate what basic emergency actions should be taken, based on hazard class. Green Sections: is organized numerically by UN identification number and provides the initial isolation distances for specific materials. Chemicals included in this section are highlighted in the blue or yellow sections. Any materials listed in the green section are always extremely hazardous. This section also directs to consult the tables listing toxic inhalation hazard materials (TIH)
NFPA 704 Hazard Identifications system
o Uses a diamond-shaped symbol of any size, which is itself broken into four smaller diamonds, each representing a particular property or characteristic. The blue diamond indicates the health hazard posed by the material. The red diamond indicates flammability, the yellow diamond indicates reactivity, the white diamond is used for special symbols and handling instructions.
o The blue, red and yellow diamonds will each contain a numerical rating of 0 to 4 with 0 being the least hazardous and 4 being the most hazardous. The white quadrant will not have a number but may contain special symbols.
MSDS will include
