A safety diamond is a visual element used to identify the types and levels of risk of some chemical element being stored or transported.
It is likely that on several occasions you have come across these types of signals and although you know what the description of the content represents, you really have no idea what each element of the rhombus means.
At first glance it may not seem that important unless you come across these often because of your job or some other factor. But it is always good to know the message that a sign or symbol wants to convey to us since we do not know at what time in life this information may be useful..
The safety diamond designated by the acronym NFPA 704 It was created in the United States by the National Fire Protection Association, this rhombus or diamond was created to give a global characteristic of easy recognition to stored or transported products.
This was done in order to clearly know how an item should be handled and so that the fire department could easily identify the material in the event of some type of accident or fire..
Later the use of the rhombus was extended to the international regulation accepted by the United Nations. In this sense, we can find this diamond or safety diamond in any country in the world and its meaning is the same.
The safety diamond or safety diamond is made up of four inner diamonds that form a larger diamond.
Each internal rhombus has a different color and each color indicates a different type of hazard, This type of rhombus is usually made of reflective materials in order to gain visibility in the event of any accident or incident related to the container or its contents..
The four hazards described in the different internal diamonds are classified on a scale of value that goes from zero to four, with zero being the minimum risk and four being the maximum risk, indicating that the material can be fatal..
Below we will make a description of each of the components of the safety diamond or safety diamond so that you are clear about what their colors mean and their different levels of risk.
The red color indicates the level of flammability or volatility in the face of fire or heat. In this sense, the red color on its scale indicates, at zero that the material is not flammable and at four, that the material is extremely volatile and flammable..
0 - Indicates that the material is not flammable
1- Materials that are not flammable at room temperature but can become so when heated, flammability above 94 ° C
2- Slightly volatile materials whose flammability is between 38 ° C and 94 ° C
3- This indicates that the material is volatile and can ignite at room temperature, that is, between 23 ° C and 38 ° C
4- Elements that can ignite at temperatures below 23 ° C and also quickly disperse in the air or evaporate.
This color indicates the level of risk that the component has in relation to the health of those who handle it or may come into contact with it in some situation. The blue on its scale indicates at zero that there is no risk to health and at four that the compound is fatal.
0- These types of compounds do not represent a danger to humans even in case of direct exposure, inhalation or ingestion.
1- Materials that can become irritating to the skin but do not represent a greater risk to health, they can even be treated directly without medical intervention.
2- This type of compound has the risk of causing permanent damage in the absence of adequate treatment, being exposed to this type of compound is immediately incapacitating.
3- Compounds that can be disabling even in short exposures, can cause permanent damage and in the absence of treatment can be fatal.
4- The maximum degree of damage to health is made up of those materials that can be fatal even when medical treatment is provided immediately.
The yellow color designates the explosive potential of compounds, this color tells us about the reactivity of the material to different exposures. On its scale, the yellow color indicates at zero that the material is not explosive and at four it indicates that the material is highly unstable even under normal conditions..
0- Materials not reactive to water or high temperatures, zero indicates that it does not have explosive potential.
1- This indicates that the material under normal conditions is highly stable, but that it may change if it is exposed to high temperatures for a long time..
2- Materials that are quite reactive to high pressure or temperature, it is also used to designate materials that can explode on contact with water.
3- Designates components that have a high volatility characteristic but that require an ignition source to explode, materials that explode on contact with water or that become explosive when heated a little.
4- Highly unstable materials that can explode even under normal conditions or by impact.
The color white is used to designate additional characteristics of the different compounds, these additional characteristics are potential dangers that they can represent for the integrity of those around them..
'W'- This symbol indicates that in no case should water be used with this compound either because the compound is volatile to it or because it reacts strangely or aggressively.
'OX' or 'OXY' - Indicates that the material by its condition is a strong oxidant.
'SA' - This special danger refers to the fact that the compound is an asphyxiating gas and is used in a preventive way not only in the safety diamond but in different places where gases are worked in very closed spaces.
'COR' or 'CORR' - These are highly corrosive compounds that can represent a high risk due to the difficulty of handling them. These corrosive materials can be acids or bases.
'BIO' - Indicates that the material involves high biological risks such as viruses or dangerous bacteria.
CRYO 'or' CYL '- Indicates that there is a cryogenic risk, that is, contact can cause immediate frostbite as is the case with liquid nitrogen.
'POI' - This acronym indicates that the material is poisonous to living things. Poi comes from the English word Poison.
'RAD' or 'RAAD' - Indicates that the material is radioactive, this callsign is the most important on the list since it is the only one that designates an extreme hazard.
We hope that this information about the Safety Diamond It helps you to know much better the world with which you interact and to prevent any danger.
