Blue red yellow and white. Colors are used to further distinguish the hazards with red referring to flammability blue referring to health and yellow referring to instability.
Nfpa 704 Chemical Marking And Fire Diamond
One diamond is blue one is red one is yellow and one is white as shown on image.
Hazard diamond colors. Click on the hazardscolors for the specific hazards represented by the numbers. Each division is color with Red blue while and yellow which indicates health hazards flammability reactivity and special hazards that chemical may profess during a fire. Numbers inside each diamond range from 0 no risk to 4 extreme risk.
The top square is red and describes flammability hazards the leftmost square is blue and describes health hazards and the rightmost square is yellow and describes reactivity hazards. The NFPA diamond consists of four color-coded fields. The four bars are color coded using the modern color bar symbols with blue indicating the level of health hazard red for flammability orange for a physical hazard and white for Personal Protection.
The number in each inner quadrant represents the hazard rating for each of the 3 categories. Blue indicates health hazard. The blue diamond is the health.
A diamond divided into four smaller diamonds each given a color code and number to signify a specific hazard. The different colors represent three different types of hazard that may be associated with chemicals. The National Fire Protection Association NFPA hazard identification system uses a color-coded diamond to represent four different hazards.
The four colors are blue red yellow and white. Each color represents a type of hazard. EXAMPLE Blue Health hazard Red Fire hazard Yellow Reactivity hazard White Special hazard 0 minimal hazard 1 slight hazard 2 moderate hazard 3 serious hazard 4 severe hazard.
The numbers superimposed over the colors rank the severity or danger ranging from one to four with four being the highest rating. The NFPA 704 diamond sign used to display this information has four colored sections. NFPAs Guy Colonna explains a few key differences between the hazard labeling guidelines in NFPA 704 Identification of the Hazard of Materials for Emergency.
0 There is no fire hazard. Blue for health red for flammability and yellow for instability. The blue section of the NFPA color code symbolizes health hazards.
Blue for health red for fire yellow for reactivity and white for anything else you need to know to be able to approach and use this chemical safely. Fire diamonds located on tanks and buildings indicate the level of chemical hazard located there. Flashpoint above 200F 93C.
Distinguish the hazards they are also colorcoded as follows. Each section is used to identify a different category of potential hazards. 0 - Will not burn 1 - Must be preheated for ignition.
The shades of red. The NFPA diamond provides a quick visual representation of the health hazard flammability reactivity and special hazards that a chemical may pose during a fire. Severity is indicated by a numerical rating that ranges from 0 as the minimal hazard to 4 as a severe hazard.
The NFPA diamond is designed to give general hazard information for chemicals. The diamond is divided into four color-coded squares each which conveys information about specific hazards present in the area. Blue red yellow and white.
Purpose Fire diamond is to convey the instruction to fire the fighting person about the hazard. The diamond-shaped signs use the four color-coded categories to give at a glance a general idea of the hazards that personnel or observers are exposed to in any specific area.
