Explosive sign is include in a safety sign and it has a dangerous caution and/or meaning or purpose. This type of sign usually encountered in many places such as laboratories, workplace and many more. For an example, The number of hazardous substances in the laboratory can also affects the number of safety signs or symbols.
Those safety sign can be found anywhere to indicate the meaning of the contents slash effects of these substances. There are lots of symbols for chemical substances such as corrosive, toxic, flammable, explosive and others.
The large number of materials in the laboratory require those symbols or sign to distinguish each of the content inside the materials. One of the many existing symbols is an explosive sign which is usually symbolized by a circle with several sides that appear to explode.
Each Chemicals that are marked as an explosive or labelled with explosive sign means that they have a tendency to easily explode in some conditions, so anyone should take a measurement caution in handling the chemicals itself.
Type of Danger Sign and Its Symbols Meaning
Explosion of materials labelled with explosive symbols can be triggered by several things, from a light touch until something more powerful such as due to impact, heating, friction, certain reactions, blows or even due to sparks.
Chemicals with explosive symbols can even explode when it is located in the absence place of oxygen, therefore actual care is really needed in treating or handling them.
Chemicals with an explosive symbols or signs, can be seen from an example like, TNT, Ammonium Nitrate, and also Nitrocellulose. The employee must have or needs a better knowledge regarding handling the chemicals with explosive properties in order to avoid the possibility of an explosion risk.
Apart from the explosive signs, there are other dangerous symbols that you should know the existents to avoid any workplace accidents that might be life-threatening for human.
Corrosive Danger Sign
The safety sign and symbol of corrosive explosive signs are usually depicted with hands and also objects that are seen to have an injured part due to a drop of a substance. The corrosive symbol itself means that the substance can damage living tissue for its corrosive behaviour.
This sign is usually used or owned by several chemical substances with a certain level of acidity. Materials with corrosive properties have a pH level of < 2 or > 11.5. Chemicals that usually have this symbol are for example sulfur oxides and chlorine.
In addition to its properties that damage tissues when in direct contact, this material is also dangerous when humans inhale its vapors, or even just when someone making direct contact with the eyes and then cause irritation. The R-phase for corrosive materials, namely R34 and also R35.
Flammable Danger Sign
The next Danger Sign type coming from hazardous flammable chemical or commonly understood as flammable sign. Materials with those properties are divided into 2 categories, which are extremely flammable sign and highly flammable sign. Each has different meaning than the others.
Extremely flammable means that it has a real point at 0°C and also a boiling point of 35°C. Usually a material that has this property will be in the form of a gas when it is at normal temperature and when it is stored in a high pressure airtight tube. The R-phrase for combustible materials is R12.
Highly Flammable sign means that the chemical with flammable substance has a flash point of 21 °C and an unlimited boiling point. In this type of chemical, the influence of humidity is very significant because it needs special treatment or care.
Highly flammable substances can be stored it in a room that has high humidity air to prevent the possibility of fire. The R-phase for this material is usually symbolized by R11.
Toxic Danger Sign
Usually depicted with a skull symbol to indicate that the substance is toxic. Poisoning that can be caused by chemicals with this symbol, among others, can cause death when consumed in high levels, or are acute and chronic. Many people think that this material is toxic only when it enters the mouth, but materials with the toxic symbol can also cause poisoning through inhalation and direct contact.
Some examples of chemicals with toxicity contained in it are Arsenic Trichloride and Mercury Chloride. To avoid this type of toxic hazard, users must well understand about how to treat these chemicals and how to use them. This must be done to avoid any possibility of poisoning.
Usually when the users use any of the toxic chemical, they can take a precaution by avoiding direct contact with the skin, using gloves and masks and also not swallowing any of that substances.
Oxidizing Danger Sign
Commonly called oxidizing. It can be interpreted as the chemicals are easy to evaporate and easily burn through the oxidation process. Usually the material burns caused by a chemical reaction with hot air, a spark, or by the reaction of a material that has reducing properties. Chemicals with oxidizing properties can be seen in Hydrogen Peroxide and Potassium Perchlorate. The R-phase for easily oxidized materials is R7, R8 and also R9.
