I have a journeyman electrician friend who often works on construction sites. She told me about one job where the boss made sure everyone had water on hand – which is great – but the sign reminding employees to stay hydrated was posted behind a door in the break room.

Putting up signs where people least need them is a real missed opportunity. It’s easy to forget to take care of yourself or make sure you stay safe when you’re busy doing your job, so putting signs like this one outdoors makes a huge difference.

When she mentioned it to a supervisor, the sign got moved and now the workers can see the reminder when they actually need it.

Staying Hydrated

Water makes up at least two-thirds of the human body. It’s no surprise, then, that we need to drink plenty of it to make sure that our body functions properly by keeping joints and eyes lubricated, the skin healthy, and digesting functioning properly.

Taking in enough water is even more important during the hotter months of the year, when water evaporates more quickly from the skin. When the water content of the body is reduced, it needs to be replaced soon enough or it will affect workers’ performance on the job, and possibly their health and safety as well.

Dealing with Dehydration on the Jobsite

Staying hydrated is one of the very best things any worker can do to stay healthy on the job site. Drinking enough water is critical for the proper functioning of the human body. A dehydrated worker is likely to experience symptoms of stress and disorientation that can be life-threatening on the job.

Drinking plenty of water while working outdoors on hot days is a serious matter and it’s about more than just comfort. Dehydration causes strain on the heart, which makes it harder for blood to circulate. Add to this the fact that there is already plenty of stress on the job, not to mention all of the physical and muscular exertion, and you have a recipe for serious health complications.

The Centers for Disease Control and Prevention (CDC) advises that workers should be reminded to drink water frequently throughout the work day to maintain good hydration. This is especially critical when temperatures are high.

Having plenty of cool water nearby, within easy reach of workers who are already doing physical labor, is mandatory. But you should also consider taking a few extra steps. Posting signs outdoors to remind employees about the dangers of dehydration is a good way to keep reminding them that there’s nothing heroic or admirable about working through the thirst.

It’s also a good idea to make proper hydration a part of your toolbox talks at least once a week. If reminding a group of adults to drink their water seems too basic, remember how easy it is to get caught up in the work they’re doing out in the field. That weekly reminder could make all the difference.

How to Spot Dehydration in Workers

Reminding workers to stay hydrated is just one part of the equation. You also need to make sure everyone on site can identify the symptoms of dehydration and assist any employee who might be experiencing them.

The signs of dehydration are similar to the symptoms of heat stress. They can include:

  • Dry mouth
  • Muscle cramps
  • Sleepiness
  • Rashes or redness on the skin
  • Dizziness
  • Confusion
  • Rapid pulse
  • Urine in low volume and more yellowish or darker than normal

No one can determine if a worker is properly hydrated better than that they can. But during periods of extreme heat, encourage employees to look out for each other. A reminder to rest and drink some water can make a big difference.

Don’t Wait for the Symptoms

Workers who feel a sense of thirst or who are sweating profusely will need to drink water more often. They should never wait for severe symptoms of dehydration to show before taking action. Rest, shade, and water should be used at regular intervals to ensure a safe and productive workday.
