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.

Hazards and Control Measures of working Alone at a workplace

 

Risk and Control Measures of Alone Working

 

 

What is a lone worker?

A lone worker is the one who works on his own without direct or close supervision and can be found in a different type of activities. Mostly we consider lone worker which is working alone without direct supervision and without his co-workers as well. 

 

Here are some examples of lone worker:

 

Watchman which are working alone most of the times.

Personal which are working outside the normal working hours.

Agriculture worker are also the example of lone working.

Drivers and operators are also fall in lone worker category.

Crane operator specially Tower Carne Operators

 

 

We have to consider about the safety arrangements for the lone workers as we care about the workers which working on the controlled workplace. It is important to make sure that the worker which is performing the activity alone is competent enough. Is he able to handle all the risk which can be there?

For the personal which are working out side the normal working hours can be instructed to work in the normal working hours. 

 

Things which need to be keep in mind related to lone working:

 

1.      Is there any risk of violence for the lone worker?

2.      Does the place is safe to work?

3.      Can young personal involved in the lone working?

4.      Can women be at risk?

5.      Is the medical condition of the worker suitable to allow him to work alone?

6.      Can a worker use effectively all the temporary tools, plants and equipments?

7.      Experience personal should educate the worker about the risks and control measure. Basically, teach them what they can do in case of emergency while working alone.

 

 

  

Only consider experience employees for lone working, new employee should not be sent for the job until they are fully qualified for the task.  

 

Regular communications required for the employees which are working alone. It could be achieve by radio or mobile phones and supervisors responsibility is there to check them time to time.

If no other means of communication is there, automatic alerts should be activated which raises the alarm in case of emergency.

 

  

Risks of working alone

 

Alone workers may face similar risks to others in your company, but the reality is that if they are lonely, the risks of a incident increase.

In particular, additional work-related risks include:

 

Lack of supervisors

Accidents

Emergency

Medical conditions

Violence or threats from others

 

These risks mean additional risk. If you are working alone, and there is no one around you to help in an emergency. If something goes wrong or you are in trouble, how will anyone else know that you are in need of help? If you have an emergency and no one around you then it will create delay, that delay can be fatal some time. 

That is the reason it is always important to reduce the risks before working alone.

 

Remember that when working alone, there is no backup on site and no other team member comes close for helping.

 

Control measures

 

Steps to overcome the hazards of the working alone:

 

Proceed with eliminate the need to work alone and make sure there are at least two people available all the times.

 

Working alone time amount can be reduce.

  

Provide emergency alarms for the lone worker in the workplace as a guideline for emergency services.

 

Provide an individual alarm for mobile users.

 

Provide suitable communication devices (such as radios and mobile phones) to alone workers.

Pre Task Safety Briefing for a specific task at a workplace

 

Pre Task Safety Briefing 

 

 

We can say that these are a kind of toolbox talk. Pre-task briefings are used to make a specific task safe. In this we can identify the hazards which could be there and control measures to control these hazards and also about the Personal Protective Equipment which are required to commence the job safely and securely. In others it works like on the spot risk assessment.

  

We will cover here all the topics about Pre-Task Briefings. Hazards can happen before even starting the activity i.e., unloading or material shifting for that activity. So, it is important to start with pre task briefing. It is better to conduct it in the same language which your crew members are speaking otherwise they are unable to understand the hazards due to language barrier.

It needs to be conducted if the work procedure change or even if the machinery or equipment changes during the activity. These few minutes which we spend on pre task briefing will help a lot to educate the workforce.

 

These pre task briefings are normally given by a competent personal, supervisor, engineer, leadsman or workplace safety officer some time. It should be conducted on the real workplace so that we can take input from the workers.  

 

In the past few years, I have investigated or reviewed a large number of incidents reports. Impotent thing in my mind is that how many of them included comments from workers involved in accidents or injuries. Most of the time the answer was I did not think about that or that was not in my mind. They were not engaged that is the biggest reason of incident on workplaces.

The input from worker which are the actual one who perform the task and also in real danger.

 

 

Infect, each pre task briefing should include review the work sequence, list the hazards associated with the work, and summarize how to control these hazards. 

Now we will discuss how it will be conducted:

Categorized all the parts of the activity.

Understand the job and responsibilities related to the job.

Identify the hazards which are associated with the activity.  

Control measures which are required to make the workplace safe.

Discuss about the tools and equipment and also about the suitable PPE (Personal Protective Equipment) to perform the job safely.

How many pre-tasks briefings we need to conduct? Frequency of the Pre-Task Briefing.

How to respond incase of emergency.

 

It is mandatory that each and every employee which is involved in the activity should sign on that form and verify that they have undertaken the work instruction.

 

If procced correctly these pre task briefing will help the workers to make them familiar with the activity and reduce the hazards or chances of getting injured.

  

Pre tsk briefings are the key to the framework if you have not started yet start conducting these it will surely help to achieve a safe workplace.

If you are already conducting pre task briefings then keep it up the good work. Enjoy

Violence at Workplace

 

What is Violence (Work Related)?

 

Definition:

“Any incident in which a worker or an employee is threatened, attacked or abused by a member of public in situations that arise during their employment is called work related violence”.

Another group of workers who are particularly at risk are lone workers. The risk of violence against a lone worker was listed as a major threat, as well as difficulty accessing aid and assistance, if anything goes wrong, including violent incidents.

 

 

Employment Sectors and work activities in which we can have violence incidents

 

There are chances of violence in a workplace which relates to these sectors:
