What type of fire extinguisher is most commonly required on construction sites?

The most commonly required fire extinguisher on construction sites is the Class A, B, and C extinguisher. This is due to the diverse range of potential fire hazards present in construction environments. Class A extinguishers are designed for fires involving ordinary combustibles like wood, paper, and cloth, which are often found on construction sites. Class B extinguishers address flammable liquids and gases, such as solvents, oils, and fuels, which are also prevalent in various construction activities. In addition, Class C extinguishers are used for electrical fires that may occur due to power tools and equipment commonly used on construction sites.

The requirement for a fire extinguisher that covers all three classes ensures that workers are adequately protected and prepared to respond to different types of fires that may arise in this dynamic and changing environment. This comprehensive approach is crucial for maintaining safety standards and minimizing the risk of injury or damage during construction operations.
