How Does The Weather Affect Construction Site Safety?

Along with all of the other health and safety risks on a construction or demolition site, the weather can play a significant role in increasing the chances of an accident or incident occurring. The most obvious weather conditions which pose a danger are:


  • Strong Winds
  • Temperature
  • Lightning
  • Heavy Rain
  • Fog


  • Strong Winds

    One of the main dangers from strong winds will be to people and loose material which is at a height, as it is likely to be more exposed and therefore more susceptible to high winds. Cranes and towers are particularly at risk. People working at height can be blown to the side, increasing the chances of them falling if there is insufficient side protection or harnesses to stop them from falling. If the wind is strong, there can be a risk of materials such as roof tiles and fast-moving debris striking a person. Also, the wind can whip up dust which can damage or irritate eyes, as well as aggravating conditions such as asthma.


    Strong winds can also make it difficult to hear properly, so much so that workers may be oblivious to approaching vehicles if they cannot hear them coming.


    Temperature

    Extremes of temperature can directly or indirectly increase the probability of an accident. Work taking place in extreme cold runs the risk of poor visibility through frozen up windscreens, as well as creating slip hazards from ice.


    In hot temperatures, workers may suffer from conditions such as dehydration and sunstroke which can affect their judgement and reaction times, and is particularly perilous when driving a heavy vehicle around or operation machinery. They may also give in to temptation to cool down by not wearing protective equipment such as hard hats or high-visibility jackets, which increases the odds of them being injured or killed by a moving object or falling item. Along with causing issues for people, high temperatures or the intense glare of the sun can cause overheating and fire risks to machinery and flammable materials on site.


    Extreme temperatures can also cause machinery to not operate correctly or break down completely. Not only will this cost time and money, but can also be extremely dangerous if the temperature were to damage or cause a failsafe feature not to function whilst in use.


    Lightning

    The abundance of metal on a construction site means that the risk of lightning is very real, particularly for objects which are tall and higher up such as cranes and scaffolding. Acting as conductors, there is a chance they could be struck by lightning, causing electrocution, fires, or explosions as a result.


    Heavy Rain

    Apart from being unpleasant to work in, the presence of heavy or torrential rain will reduce visibility for the drivers of vehicles, and will turn the ground into mud which poses its own risks to the health and safety of site workers.


    Fog

    Fog can be particularly dangerous for the workers on a construction site as it greatly reduces the visibility of everyone. The drivers of vehicles will not be able to see very far ahead, meaning that they may not be able to react in time if a person or object is in the roadway. The driver may even drive off the road if they cannot see where the edge is, increasing the chances of them colliding with something or driving over the edge of a steep drop. Along with the visibility issues for the drivers, workers on the ground will also find it difficult to see approaching vehicles and get out of the way in time.


    Conclusion

    The unpredictability and power of the weather can create unforeseen problems and delays. Even with the most comprehensive project management and all of the health and safety courses and training in the world, there are still risks of injuries and accidents occurring, which will be greatly increased with the presence of one or more of the weather conditions listed above.

    Need an Accredited Course?

    Along with designing bespoke health and safety training programmes, we also run the accredited NEBOSH, IOSH and ConstructionSkills (CSkills) health and safety courses as open courses at selected venues across the UK, as well as in-house for those companies who have a number of employees requiring the training, as it will be much more cost effective than sending them all onto a scheduled open course.
