Top Takeaway: Heat stress and the risk of falling are both serious hazards when working at height in the summer. Combined they can be deadly, so stay cool and plan ahead to keep everyone safe this season.
Summer is synonymous with construction. Its consistent weather and sunny days make working outside significantly easier and safer than harsher seasons. The heat, however, is not always your friend.
Heat stress is a major problem on jobsites throughout the warmer months and can complicate already hazardous jobs, such as working at height. Here are five rules that must be followed if your site involves working at height this summer.
1. Watch the weather.
Summer weather is typically reliable. It’s hot, maybe humid, and has significantly less precipitation to worry about. While this reduces the risk of slipping, summer brings its own hazards, like heat stress and lightning storms. Keep an eye on the weather and make sure your site is prepared for anything the season can throw at you.
2. Cover up.
Heat stress occurs when your body warms up faster than it can cool down. Although it feels nice to lose the layers, exposing your skin to the sunlight increases the rate at which your body heats up. Instead of going sleeveless, wear light, loose clothing with long sleeves and legs, UV-blocking sunglasses, and sunscreen to protect yourself from the worst of the sun’s rays.
3. Stay hydrated.
Staying hydrated is the most important factor in preventing heat-related illness. Keep a water bottle close at hand throughout the day, refilling it every time you empty it. Drinking water will cool you down and keep you alert, and refilling your bottle will give you regular opportunities to step out of the sun.
4. Use appropriate fall protection and prevention.
Drier weather reduces the likelihood of slipping, but it’s still crucial to utilize the appropriate fall prevention and protection equipment for the height you’re at (WorkSafeBC has a simple guide here). Take time to lay out a fall prevention and rescue plan, making sure everyone on site is familiar with it. When you’re not wearing your PPE, store it in a cool, dry place to prevent any damage from the sun or heat.
5. Don’t wait to get help.
Getting dizzy or passing out while still at height could put yourself and others in extreme danger as they try to rescue you. Heatstroke can progress quickly, so if you start to feel symptoms such as a headache, dizziness, or you’ve stopped sweating, get back to the ground as quickly and safely as possible to get treatment.

Top Takeaway:
High temperatures are the greatest challenge for jobsites in the summer. Make sure everyone on site is hydrated, eating well, and taking time to cool down to prevent heat stress.
Summer is here, and with it comes long days and hot weather. Warmer temperatures can be exciting but are also hazardous for those who work outside or in the heat. Heat stress is a serious threat on a jobsite, so check out these best practices to stay safe this season.
1. Have a plan.
The best way to keep your jobsite running safely and smoothly this summer is to be prepared. Consider supplying additional cooling PPE for your crew, such as fans or cold packs, and organize working hours to avoid the hottest part of the day.
2. Stay hydrated and wear sunscreen.
These are the two simplest ways to avoid heat illnesses and protect your health in the long term. Drink enough water (most doctors recommend eight glasses a day) and continuously apply sunscreen to protect yourself from the heat and UV radiation.
3. Respect the sun, love the shade.
Exposure to sunlight is inevitable in the summer, but it should be avoided when possible. Create shaded areas with good air-flow to prevent sunburn and heat-related illnesses.
4. Dress right.
Sleeveless may seem the way to go on a burning day, but exposed skin means a higher risk of sunburn and sunstroke, and could even lead to skin cancer in the long term. Instead of losing layers, wear loose-fitting clothing made of breathable material, a hat with a brim, and sunglasses that block UV rays. These steps will guard your health and keep you cooler in the long run.
5. Eat right.
It’s natural to crave sugary drinks and icy treats in the summer heat but these foods will sap your energy as you digest them and leave you with a sugar crash. Choose healthy, energizing foods, like fresh fruit or low-sugar granola bars and stick to water as your drink of choice.
6. Allow for acclimatization.
If an employee is new or has been off work for a while, their bodies will need time to adjust to the summer’s heat. Start them with reduced time spent in high temperatures and increase it slowly. An acclimatized body will be able to better handle heat exposure and is less likely to suffer from heat stress.
7. Stay cool.
It’s important to allow your body to cool down after spending extensive time in the heat. Prepare air-conditioned break rooms and encourage your crew to spend time indoors after work to prevent the effects of heat stress.
8. Plan for the next day.
Your habits outside of work will also affect your ability to operate in the heat. Avoid overindulging on coffee or alcohol after-hours, as these will continue to have dehydrating effects on your body the next day.
9. Watch for symptoms.
Heat stress can progress quickly once it has begun and, if left untreated, can require time off work to recover from. Watch out for dizziness, nausea, headaches, cramps, elevated pulse, and if sweating stops. If you notice any of these symptoms, take a break in a cool area and drink lots of water. If a person becomes unresponsive, call 9-1-1 immediately.
10. Educate your crew.
While it’s important to pay attention to the health of your crew, it’s impossible to monitor everyone onsite at all times. Make sure your staff are trained to recognize the signs of heat stress and treat it immediately.
11. Know when to call it.
Some days are just too hot to work. It may be frustrating to end a workday early, but it will be more productive in the long run to preserve the health of your employees. There’s no legal cut off for when it’s too hot to work, so monitor the heat and your crew’s condition to make the wisest choice.

If you’re going to work with tower cranes, you better know your hand signals. Clear communication is essential for staying safe on the job site.
A crane operator should always use a signaler, and they should communicate according to the established code of signals. Hand signals are preferred and commonly used. In certain cases, a signaler may be required by law, especially if the operator’s view of the intended path of travel is obstructed in any way.
Here are six essential rules for crane operators and signalers:
- Only a qualified person can be a signaler. They must be trained to give hand signals to a crane operator.
- Only one designated signaler should be assigned for each crane operation. If one signaler ever needs to be replaced by another, the one in charge should wear a clearly visible badge of authority. There should never be two active signalers.
- The crane signaler must be in clear view of the crane operator.
- The crane signaler must have a clear view of the load.
- The crane operator and signaler must both keep other persons outside of the crane operating area and never direct a load over a person.
- A crane operator must obey STOP signals no matter who gives it.
Importantly, the Occupational Safety and Health Administration requires that anyone designated as a signal person must meet certain qualifications and be evaluated by a qualified individual. These regulations, in addition to a commitment to standardized signals, have helped reshape the landscape of crane safety, with crane-related deaths falling to their lowest recorded level in 2017 according to the Bureau of Labor Statistics.
Below, we have a visual guide to basic crane hand signals, including a few signals that are particular to telescopic, crawler and tower cranes. In any case, crane hand signals are an essential part of operating a crane, whether using a small carry deck crane or a larger all-terrain crane. These basic signals are even used with the largest cranes in the world. Some crane rentals also include operators and a signal person in the cost.
