Demolition hazards and control measures which we may face at a demolition site

 

 Demolition hazards & control measures 

Introduction

Demolition work involves the dismantling, destruction, or removal of structures, buildings, or other infrastructures. Demolition work can be hazardous due to the presence of numerous risks such as falling objects, electrical hazards, and exposure to hazardous substances. Therefore, it is essential to identify, assess, and control the hazards associated with demolition work to ensure the safety of workers and the general public. In this article, we will discuss demolition hazards and controls.

Demolition Hazards

Falling Objects: During demolition work, there is a risk of falling objects such as bricks, debris, and equipment. Falling objects can cause serious injuries or even death if they hit a worker or a member of the public. The risk of falling objects can be reduced by using safety nets, barricades, and warning signs.

Electrocution: Demolition work often involves the use of heavy equipment that can come into contact with overhead power lines. This can cause electrocution and result in serious injuries or death. Workers should be trained on the safe use of equipment and should be made aware of the location of overhead power lines. The use of insulated tools and equipment is also recommended.

Hazardous Materials: Demolition work may involve the presence of hazardous materials such as asbestos, lead, and mold. These materials can cause serious health problems if they are not properly handled and removed. Workers should be trained on the safe handling and removal of hazardous materials. Personal protective equipment such as respirators and protective clothing should be worn.

Noise Pollution: Demolition work can produce high levels of noise that can cause hearing loss or other health problems. Workers should wear earplugs or earmuffs to protect their hearing. Noise barriers can also be installed to reduce the impact of noise on the surrounding environment.

Structural Failure: Demolition work can cause the structure being demolished to fail prematurely. This can cause serious injuries or death to workers or members of the public. The demolition contractor should carry out a structural assessment to identify any weak points and ensure that the structure is properly supported before any demolition work commences.

Demolition Controls

Planning: A detailed demolition plan should be developed and approved by relevant authorities. The plan should identify the hazards and risks associated with the demolition work and outline measures to control or eliminate these hazards.

Training: Workers should be trained on the safe use of equipment, the handling of hazardous materials, and the use of personal protective equipment.

Equipment: The use of appropriate equipment such as cranes, excavators, and jackhammers should be used to minimize the risk of injury or damage.

Site Preparation: The site should be properly prepared before any demolition work commences. This includes the removal of hazardous materials, the installation of barricades and warning signs, and the proper support of the structure being demolished.

Environmental Controls: Measures should be taken to control noise pollution, dust, and other environmental impacts.

Supervision: A qualified supervisor should be present on site to ensure that the demolition work is carried out safely and according to the plan.

Conclusion

Demolition work can be hazardous due to the presence of numerous risks such as falling objects, electrical hazards, and exposure to hazardous substances. Therefore, it is essential to identify, assess, and control the hazards associated with demolition work to ensure the safety of workers and the general public. The use of appropriate equipment, the proper handling and removal of hazardous materials, the installation of safety measures such as safety nets, barricades, and warning signs, and the presence of a qualified supervisor are all important controls that can be used to mitigate the risks associated with demolition work. By implementing these controls, we can ensure that demolition work is carried out safely and efficiently.
