- 3. WORKING AT HEIGHT Definition: Work at height means work in any place where, if there were no precautions in place, a person could fall a distance liable to cause personal injury Working at elevated areas: • Roofs, Scaffolds, Ladders, Bigger equipments/machines include falling objects and the potential for a working platform to collapse or overturn as well as contact with overhead electrical services. • Working at height or depth of 1.8m or above to be considered as working at height and adequate working arrangements and fall protection to be made to prevent fall of persons and materials

- 14. Work at height hazards: These are acts, situations and conditions which have the potential to cause harm to anyone working at height; these hazards includes: Over-reaching Failure of a fragile surface. Unguarded holes in floors Failure of the elevated work platform (Collapse, overturn, etc.) Poor edge protection Items being poorly stored or secured Work in areas without guard rails or covers. Poor training Falling object

- 23. Work at height control measures Here are series of action that should be taken to manage all the hazards associated with work at height. To set a workable work at height control measures, proper work at height risk assessment should be carried out. This will guide the process of drawing out adequate control measures for work at height activity. Hierarchy of controls when working at height When working at height, hierarchy of control to be followed include: Avoid working at height where possible Work from an existing place of work, or use an existing means of access and egress.
- 25. Preventing falls using collective protection Preventing falls using personal protective equipment Provision of work equipment to minimise the distance and consequences of a fall, e.g. fall arrest systems Instruction and training and/or other means Where possible, work at height should be avoided, usually by carrying out tasks from the ground. If not possible, other hierarchy of controls should be adopted.
- 36. Use existing working platform Here existing safe place of work is used to carry out work where possible. This existing work platform is believe not to require additional protectiveequipment and with is no risk of falling because preventative measures are already in place.
- 37. Preventing falls using collective protection This means protecting everyone who’s potentially at risk. This involve ensuring the use of a safe working platform. Below are the characteristics of a safe working platform: The working surface must be stable and of sufficient strength and rigidity for the purpose. The working platform must rest on stable and suitably strong surfaces. It must be of sufficient size to allow safe use for persons, plant and material; the space must be suitable. Should be designed in such a way that fall from the platform is avoided. No gaps should be left on the platform.
- 38. Suitable protection, such as platforms, coverings, crawling boards or guard rails, must be provided. Measures should be taken to minimise the distance and consequence of any fall, e.g. fall arrest systems, safety nets and air bags
- 39. Preventing falls using personal protective equipment This could include equipment such as safety belts (Body harness), which restrict the worker’s movement to the extent that a fall isn’t possible. Minimise consequences using collective equipment This level on the hierarchy of control again refers to the use of safety nets or airbags. This can help to reduce the distance of a fall, and also to soften the impact of fall. Ensure workers training: Before any worker is assigned with the task of working at height, the worker needs to be properly trained. The training should cover: What is working at height Dangers of working at height
- 40. Who should work at height Safety measures to adopt while working at height Appropriate use of fall protection and its accessories. Different types of body harness, and their suitability. This will help in the choice of the best body harness for the job; they could need harness with a single lanyard or a double lanyard. If all these hierarchy of controls are adequately implemented, the hazards of working at height would have been greatly managed.

Image Reference: Conservation of Royal Kitchen, Lahore Fort Presentation - Work at Height Work at height means work in any place where, if there were no precautions in place, a person could fall a distance liable to cause personal injury. For example you are working at height if you: ■ are working on a ladder or a flat roof; ■ could fall through a fragile surface; ■ could fall into an opening in a floor or a hole in the ground. Before working at height you must work through these simple steps: ■ avoid work at height where it is reasonably practicable to do so; ■ where work at height cannot be avoided, prevent falls using either an existing place of work that is already safe or the right type of equipment;
- 42. Lahore Fort – Conservation of Picture Wall Examples for each of the above steps to help you comply with the law. ■ do as much work as possible from the ground; ■ ensure workers can get safely to and from where they work at height; ■ ensure equipment is suitable, stable and strong enough for the job, maintained and checked regularly; ■ make sure you don’t overload or over reach when working at height; ■ take precautions when working on or near fragile surfaces; ■ provide protection from falling objects; ■ consider your emergency evacuation and rescue procedures.
- 43. Lahore Fort – Conservation of Picture Wall What are the most common causes of accidents when working at height? Roof work is high risk and falls from roofs, through fragile roofs and fragile roof lights are one of the most common causes of workplace death and serious injury. As well as in construction, these accidents can also occur on roofs of factories, warehouses and farm buildings when roof repair work or cleaning is being carried out. The following are likely to be fragile: ■ roof lights; ■ liner panels on built-up sheeted roofs; ■ non-reinforced fiber cement sheets; ■ corroded metal sheets; ■ glass (including wired glass); ■ rotted chipboard; ■ slates and tiles. What do you need to consider when planning work? The following are all requirements in law that you need to consider when planning work at height. ■ take account of weather conditions ; ■ check that the site is to be safe; Each place where people will work at height needs to be checked ; ■ stop building materials or objects from falling; ■ plan for emergencies and rescue procedure
- 44. Conservation of Altit Fort – GB Hunza (1000-Years) How do you select the right equipment for a job? ■ provide the most suitable equipment ; ■ take account of factors such as: -the working conditions (eg weather); - the nature, frequency and duration of the work; - the risks to the safety of everyone where the work equipment will be used. What must employees do? Employees have general legal duties to take reasonable care of themselves and others who may be affected by their actions, and to co-operate with their employer to enable their health and safety duties and requirements to be complied with. For an employee, or those working under someone else’s control, the law says they must: ■ report any safety hazard they identify ; ■ use the equipment and safety devices
