How Safety Of The Workers Can Be Ensured During A Demolition Operations
2. Personal Protective Equipment (PPE) Must Be Worn – During demolition, it’s vital for all employees to wear the correct PPE. As a minimum, 5-part PPE must be worn at all times on site by any operative, including:

Hard Hat Safety Glasses High-Visibility Vest/Jacket Safety Gloves Steel-Toe Capped Boots.

Our Safety Health Environment and Quality (SHEQ) Department manages the distribution of PPE to all of our operatives, ensuring we comply with British Standards (BS) and other relevant standards. The required standards of PPE can vary, depending on the project being undertaken or a client’s specific requirements.

We ensure that all our PPE satisfies each circumstance. All of our PPE is also compliant with HSE regulations, and we supply operatives with any specialised PPE outside of the basic 5-part, for example, face masks, welding masks, fire-proof overalls, Kevlar gloves, or anything else needed to safely carry out a specific task.

The stringent management of our PPE store by our SHEQ department allows the correct PPE to be allocated to the correct project, without delay or risk to safety to any personnel.

What are the safety measures for demolition work?

Work safely – Carry out the demolition work in a sequence that prevents you from falling from or through the building, and that prevents the building or parts of the building from collapsing. Also, make sure to protect yourselves with railings and scaffolding and by covering holes in the roof and floor partitions.

What is a risk assessment for demolition works?

Before any demolition or structural alteration work can begin on your project, first you will need to identify any potential hazards which may harm the workforce and surrounding areas. A thorough risk assessment should be completed that will help to highlight these problem areas which can then be used to create a method statement.

  • How should a risk assessment be carried out? By doing a risk assessment, it gives you a chance to assess the key risks and outline how they can then be minimised during the project.
  • As well as this, you should be assessing the impact on the surrounding buildings and road network to ensure minimum disruption.

You should carry the assessment out by first looking at the hazard and the likelihood of it causing harm or injury during the project. After that, outline how you are going to reduce or mitigate the possibility of any damage happening. What should be assessed? A demolition risk assessment should look at potential dangers and risks for the following:

Falls from height – includes risks of workers falling from edges, though fragile surfaces, openings, and partly demolished floors Fire – includes risks from tools that cause sparks, heat, or flames Hazardous materials – includes asbestos, dust, respirable crystalline silica, paints, acids, microbiological hazards, flammable liquids, and unlabelled drums Uncontrolled collapses – consider the age of the structure, its use, nearby buildings, and type of construction Falling materials – includes flying debris and premature structural collapse Vibrations and noise – includes hand tools and machinery Connected services – includes electricity, water, gas, and telecommunications Worker involvement – includes awareness of the risks and precautions of the worksite

Each of the above should be recorded with a risk level and the likelihood of it occurring. These risk levels are usually indicated as:

Low risk Medium risk High risk

There is no set way that you should carry out and record a risk assessment, however, it should always be modified for the complexity of the demolition work being undertaken. The Health and Safety Executive allows access to a Construction Phase Plan that can be used to help you plan and organise the job whilst ensuring the project is carried out without risks to health and safety.

Writing the Method Statement Once the risk assessment has been completed, a method statement should be written to describe the safety precautions you will need to put into place in order to control the identified risks and carry out work safely. Each method statement should be a bespoke methodology for the current project and will take into account the protection of the workforce, the public and maintaining the structural integrity of the building whilst the demolition is carried out.

Even more, the method statements should not just suggest control measures; they should detail exactly how you are going to implement them. It should be written as clearly as possible so that the statement can be used as easy as a checklist for the needed safety precautions.

  • It’s important to note that if tasks are carried out in new locations or require new equipment, the statement should be reviewed and where necessary, rewritten to make sure the health and safety requirements are still relevant.
  • This document is proof that you are carrying out tasks safely and legally so accuracy should be a priority for all projects.

What you should include A method statement should set out the task in a logical, step-by-step manner so that clear instructions can be given to the workers. It is common for them to be put into four sections, for example: Section 1 – header information used to provide information to your staff or prospective clients, the following bullet points can be used for this.

Title and a brief description of the task Company details Location of where the task will be carried out, including address Name of the person who completed the method statement Full description of the work to be carried out including step by step guide Work equipment and tools required

Section 2 – a summary of the main hazards and as a result, the control measures that must be implemented. Section 3 – a description of the task in more detail:

Staff & training Permits to work Machinery shutdown and lock off procedures Site Access and Egress Material Handling Scaffold & Access to height Background and preparation Welfare and first aid

Section 4 – the step by step guide which provides more detail on the steps that must be taken for the project to be carried out safely. As every demolition project comes with its own risks, it’s important to make sure you hire professionals with the experience to know what to look for during risk assessments.

What are the hazards associated with demolition activity?

Assessing for Hazardous Substances – During demolition, exposure to hazardous substances is likely. During demolition, exposure to hazardous substances is likely. To prevent and reduce the hazards associated with the exposure to hazardous substances, do the following:

  • Conduct worksite inspections prior to the start of operations to assess for the presence, contents, and condition of tanks and equipment that might contain hazardous chemicals, gases, or flammable materials.
  • If the condition of tanks or equipment is suspect, avoid disturbing them until after the assessment is done and a plan of action is developed to reduce exposure or eliminate the hazardous substances.

Purge lines, tanks, and equipment containing hazardous chemicals, gases, or flammable materials.

What is risk assessment for workplace safety?

Risk assessment is the process of identifying safety and health hazards associated with work, assessing the level of risks involved, and prioritizing measures to control the hazards and reduce the risks.

What are the environmental hazards of demolition?

Sediment Control: During demolition and excavation works soil becomes disturbed, both a side effect of removing the house and tracking trucks and excavators over the site. This can lead to accelerated erosion or soil and sediment being carried off the site by rain and polluting local waterways.

What are the three main types of hazards in the building industry?

The Main Causes of Injuries in Construction – There are three leading causes of injuries due to workplace hazards in the construction industry. They are manual handling injuries, falls, slips and trips, and being hit by moving objects.

What chemicals are used in demolition?

What are three methods to reduce the impact of control hazards?

What are the main ways to control a hazard? – Back to top The main ways to control a hazard include:

  • Elimination : remove the hazard from the workplace.
  • Substitution : replace the hazard (e.g., hazardous products, machines, etc.) with a less hazardous one.
  • Engineering Controls : includes designs or modifications to plants, equipment, ventilation systems, and processes that reduce the source of exposure.
  • Administrative Controls: controls that alter the way the work is done, including timing of work, policies and other rules, and work practices such as standards and operating procedures (including training, housekeeping, and equipment maintenance, and personal hygiene practices).
  • Personal Protective Equipment : equipment worn by individuals to reduce exposure such as contact with chemicals or exposure to noise.

These methods are also known as the “hierarchy of control”. For more information, please see the OSH Answers document Hierarchy of Control.

What is the most effective control measures?

1. Eliminate the risk – The most effective control measure involves eliminating the hazard and its associated risk. The best way to eliminate a hazard is to not introduce the hazard in the first place. For example, you can eliminate the risk of a fall from height by doing the work at ground level.

Eliminating hazards can be cheaper and more practical at the design or planning stage of a product, process or workplace. In these early stages, there is more scope to design to eliminate hazards or to include risk control measures that are compatible with the requirements of the original design and function.

Employers can also eliminate hazards and risks by removing the hazard completely. For example, removing trip hazards on the floor or disposing of unwanted chemicals eliminates the risks they create. It may not be possible to eliminate a hazard if doing so means you are unable to make the end product or deliver the service.

What is effective control of hazard?

Conclusion – When dealing with hazards, using the best hazard control measure is important. The hierarchy of controls is a great way to select the best hazard control measure. Remember, always select the most effective hazard control measure first. Then, if that hazard control measure is not possible, select the next most effective one until an acceptable level of risk is achieved.

What is the NFPA standard for demolition?

NFPA 241 is the Standard for Safeguarding Construction, Alteration, and Demolition Operations.

How controlled demolition of building is carried out?

What is a Controlled Demolition? – Generally speaking, the term ‘controlled demolition’ refers to the demolition of a building or structure by means of explosives. Demolition using explosives, sometimes called an implosion, ensures the strategic collapse of a building or structure by placing explosive materials in a pre-determined, detailed sequence and detonating them at a pre-arranged time.

Site preparation for demolition is detailed and thorough, regardless of the method of demolition. When preparing a site for demolition by explosive means it all depends on the structure. A simple structure like a chimney can be prepared for a controlled demolition in less than a week but larger, more complex or multiple structures can take up to six months of preparation to remove internal walls, drilling holes for placing of explosives, wrapping columns with fabric and fencing before firing the explosives.

Although using explosives as a method to demolish indicates that the building or structure will be ‘blown up’, this is not actually the case. Controlled demolition employs a serious of small explosions, strategically placed within a structure, progressively detonated encouraging a collapse by weakening or removing critical supports.
