Health, Safety, Security and Environment

Working at height remains one of the biggest causes of fatalities and major injuries. Common cases include falls from ladders and through fragile surfaces. ‘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 a fall through a fragile roof).

What do I have to do?

You must make sure work is properly planned, supervised, and carried out by competent people with the skills, knowledge, and experience to do the job. You must use the right type of equipment for working at height.

Take a sensible approach when considering precautions. Low-risk, relatively straightforward tasks will require less effort when it comes to planning and there may be some low-risk situations where common sense tells you no particular precautions are necessary.

Control measures

First assess the risks. Factors to weigh up include the height of the task, the duration and frequency, and the condition of the surface being worked on.

Before working at height work through these simple steps:

  • avoid work at height where it’s reasonably practicable to do so
  • where work at height cannot be easily avoided, prevent falls using either an existing place of work that is already safe or the right type of equipment
  • minimize the distance and consequences of a fall, by using the right type of equipment where the risk cannot be eliminated

For each step, always consider measures that protect everyone at risk (collective protection) before measures that only protect the individual (personal protection).

Collective protection is equipment that does not require the person working at height to act for it to be effective. Examples are permanent or temporary guardrails, scissor lifts, and tower scaffolds.

Personal protection is equipment that requires the individual to act for it to be effective. An example is putting on a safety harness correctly and connecting it, with an energy-absorbing lanyard, to a suitable anchor point

Dos and don’ts of working at height

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
  • take precautions when working on or near fragile surfaces
  • provide protection from falling objects
  • consider emergency evacuation and rescue procedures

Don’t…

  • overload ladders – consider the equipment or materials workers are carrying before working at height. Check the pictogram or label on the ladder for information
  • overreach on ladders or stepladders
  • rest a ladder against weak upper surfaces, eg glazing or plastic gutters
  • use ladders or stepladders for strenuous or heavy tasks, only use them for light work of short duration (a maximum of 30 minutes at a time)
  • let anyone who is not competent (who doesn’t have the skills, knowledge, and experience to do the job) work at height

working at Height checklist should be used to evaluate the working hazards and type of falling Protection the checklist below can help you and include the following Items:

Worksite Inspection 
  1. All the workers have been explained safe work-procedures? 
  2. A well-developed Communication system have been made and explained to the workforce 
  3. Adequate illumination has been ensured. 
  4. Work-area inspected before starting the job. 
  5. The area below the worksite barricaded, especially below hot works 
  6. Workmen provided with bad / box to carry bolts, nuts and hand tools. 
  7. Arrangement for fastening hand tools made. 
  8. All work platforms ensured to be of adequate strength and ergonomically suitable. 
  9. Fabricated made shift arrangements and checked for quality and type of material welding,  anchoring, etc.
