quadrant blue; flammability, top quadrant red; reactivity, bottom quadrant yellow; and special hazards, bottom quadrant white. (An Introduction to Hazardous Materials: Unit 3) Utilizing the NFPA 704, fire fighters visually inspect the information from a safe distance. As a result of information provided in the NFPA 704, hidden dangers will be quickly exposed; thereby enabling emergency workers to recognize the appropriate personal protective equipment to wear within the appropriate time constraints. Without
Hazardous materials can be important in everyday life when properly handled. However, when improperly handled, they can result in injury, death, and destruction as well as have lingering effects that may last for years to come. To address the risk of an uncontrolled hazardous materials release, there must be a coordinated effort to identify, locate, and quantify the hazardous materials in a particular location (Drexel University Safety & Health, 2001). Typically, industry and government agree that
Therefore, two hazardous materials identification systems have been developed. The first system is the National Fire Protection Association's (NFPA) 704 System, which provides immediate information on chemical hazards during a response to fixed facilities by indicating the product's health, fire, reactivity, and special hazards. This information is necessary for firefighters and HazMat responders
1. Sodium Chloride has a higher boiling point than water, so when salt is added to water, the solution has a higher boiling point than pure water. The sodium ions and chloride ions present in sodium chloride disassociate and dissolve in water. These ions interfere with the dipole interactions that occur between molecules of water. The dissolved sodium ions and chloride ions require more energy to separate from the water molecules in the solution than the water molecules from themselves, so the boiling
