Electrical Safety Signs and Symbols

The safe working procedure includes Safety precautions during the execution of work and shall the site shall be kept safe even after working hours are over.

All safety gears should be wore by the working persons and the equipment must be handled in correct way.

The instructions in simple form play a crucial role in such cases. But the time required to go through text material is more.

During emergency, the time required to react is very less so safety sign play a very important role.

Requirements of Safety Signs

The requirement of safety signs are as below:

>> It should be illustrative i.e.the person must understand its meaning easily.

>> It should convey the instruction easily.

>> It should be Pictographically so that it is easily understood by all persons.
>> Sometimes text is to be used. The text used should be easy to read and understand. Preferably it should be in local languages.

>> By seeing safety sign the person should be in a position to initiate immediate action.

>> Colour codes play an important role in conveying a message regarding safety. Each safety colour has a specific meaning. The colour of the sign specifies the nature of the sign.

  • Red signs are prohibitive.
  • Blue signs are mandatory.
  • Yellow signs are warnings.
  • Green is used for safe condition and first-aid signs.

Electrical Safety Signs and Symbols

Some Electrical Safety Signs and Symbols which is use in industries and day to day life is shown below along with description:

1. Warning sign

Warning sign in electricity
Warning sign

  • Warning sign giving warning of hazard or danger.


2. Overhead Load

Overhead load sign
Overhead load sign
  • There is a material handling going on by crane overhead.


3. Caution sign

Obstacles caution sign
Caution sign
  • There is obstacles in the way


4. Material Flammable

Material flammable sign
Material flammable sign



  • The material is Flammable.


5. Direction Sign

Direction signs

  • It used for route direction


6. Height Restrictions

Raised platform sign
Height restrictions or Raised Platform sign


7. Fire Exit Sign
Emergency Fire Exit Sign
Emergency Fire Exit Sign


8. First Aid Facility Sign
First Aid Facility Sign
First Aid Facility Sign


9. Fire Extinguisher Sign

Fire Classes and Their Prevention

Fire Classes and Their Preventions are described below:

Class A Fire

Class A Fire Symbol
Class A Fire Symbol

Fire involving combustible material such as wood, paper, cloth, rubber, plastic requiring the heat absorbing effects of water, water solutions.


Class B Fire

Class B Fire Symbol
Class B Fire Symbol

This type of fire involves flammable or combustible liquids, greases, petroleum products and similar materials for extinction, a blanketing effect is essential.


Class C Fire

Class C Fire Symbol
Class C Fire Symbol

Which involves flammable gases, substance under pressure including liquefied gasses.

Here it is necessary to dilute the burning gasses at very fast rate with an inert gas, Dry chemical powder or carbon-di-oxide.


Class D Fire

Class D Fire Symbol
Class D Fire Symbol

Fire involving combustible metals such as sodium, magnesium, zinc, potassium. These burning metal react with water and water containing agent.

Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino

Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino Introduction to Arduino | Pin Function of Arduino | Working Process of Arduino Introduction To Arduino Arduino is an Italian company that designs and manufactures Open Source Hardware (Microcontroller) and Open Source software or IDE (Integrated Development Environment). Arduino hardware is such a programmable computerized platform, by working on which the user can combine the hardware and software and prepare the electronic brain according to his own and can control the electronic devices from that electronic brain. What is arduino? If you want to understand more easily, then we can say that Arduino microcontroller is an empty brain, in which you can upload memory by coding or programming through arduino software, so these are called open source. Arduino works like a CPU of a board computer. Right now the microcontroller of the arduino of this time that we can take up is lik

Variable Inductance Transducer | Classification Of Variable Inductance Transducer

Variable Inductance Transducer | Classification Of Variable Inductance Transducer Variable Inductance Transducer | Classification Of Variable Inductance Transducer These are based on a change in the magnetic characteristic of an electrical circuit in response to a measurand which may be displacement, velocity, acceleration etc. Variable inductive transducer may be classified as follows: 1.Self-generating type In this type voltage is generated because of the relative motion between a conductor and a magnetic field. These may be further classified as follows: (A)Electromagnetic type (B)Electrodynamic type (C)Eddy current type 2.Passive type In this type the motion of an object results in change in the inductance of the coils of the transducer. These may be further classified as follows: (A)Variable reluctance (B)Mutual inductance (C)Differential transfer type 1.Self-generating Type (A)Eleotromagnetic t
