  • 2. 2 | Preventing Heat Illnesses at the Construction Site Are you doing everything you can to minimize your workers’ exposure to heat-related illnesses? Does your company have a heat illness prevention program in place? We’ve got you covered with these tips and guidelines for keeping your workers safe and productive during these hot summer days.
  • 3. 3 | Preventing Heat Illnesses at the Construction Site TRAINING Training should be provided to all employees and supervisors working in high temperatures for any extended amount of time. Topics covered in the training should include how heat can affect the body, how to identify the signs and symptoms of various heat illnesses and what steps to take if a worker is experiencing symptoms of a heat-related illness or if they observe a coworker with symptoms. Stress to employees the importance of getting plenty of water, shade and rest especially on days when the temperatures are higher than normal or when they are doing tasks that put them at a higher risk of suffering a heat-related illness. Explain to workers that in addition to the heat and humidity,certain work environments like roofing or roadwork,sun exposure and body heat created by physical exertion can all lead to heat-related illnesses.
  • 4. 4 | Preventing Heat Illnesses at the Construction Site PROVIDE WATER An ample supply of cool drinking water should be provided and easily accessible for all employees on the construction site. The general rule of thumb is a quart of water per employee per hour during their shift.Remind workers they should not wait until they are thirsty. Drinking small amounts on a frequent basis is best. If workers want additional drinks at the construction site,encourage them to bring something that contains electrolytes, like coconut water or sports drinks, to replenish what is lost while sweating.
  • 5. 5 | Preventing Heat Illnesses at the Construction Site PROVIDE SHADE As a general rule, once the temperatures start hitting 80° F shade from the sun should be provided for workers during breaks and rest periods. Full shade is needed for workers to be able to cool off. Examples include tents, air-conditioned site trailers or vehicles or ventilated buildings. Workers should be encouraged to rest and cool off in shaded areas throughout the day. Shaded areas should be easily accessible especially in the event a worker begins having symptoms of heat illness and needs assistance in getting out of the sun.
  • 6. 6 | Preventing Heat Illnesses at the Construction Site ACCLIMATIZATION Workers need to get acclimatized to working in hotter temperatures. It can take anywhere from a few days to a couple of weeks for workers to full adapt to the heat. Once your body gets fully acclimatized to the heat you will begin sweating earlier and at a faster rate and the sweat will contain lesser amounts of sodium. All of this allows your body to retain more water and cool you better. Acclimatization will also improve blood flow and reduce your heart rate when working in high temperatures. Intense activity should be limited during the first few days of acclimatization.Workloads should be gradually increased each day as the body gets used to the strenuous work in the heat. It is important to monitor workers during this process as they are at a higher risk of suffering heat illness before their bodies get adapted to the heat.
  • 7. 7 | Preventing Heat Illnesses at the Construction Site MONITOR THE FORECAST As the heat index rises during the day, so does the risk level for workers to suffer a heat illness. Supervisors and safety managers should monitor the forecast for each day so that the proper protective measures can be implemented. The heat index is a combination of air temperature and relative humidity and is used to how hot it actually feels outside. OSHA recently updated their Heat SafetyTool app for iPhone and Android.Instead of manually having to enter both the temperature and humidity,the app can now automatically pull that data for your current location from the National Oceanic and Atmospheric Administration (NOAA) and calculate the heat index and risk level along with necessary precautions to take. The app lets you choose between the current data or the highs forecast for the day, or you still have the option to manually enter both the temperature and the humidity to calculate the heat index.
  • 8. 8 | Preventing Heat Illnesses at the Construction Site MONITORING EMPLOYEES Workers should be monitored frequently throughout the day to ensure that they aren’t showing any signs or symptoms of heat illness. This can be as simple as verbally communicating with all workers to more advanced measures such as checking an employee’s heart rate, temperature,blood pressure and water loss.Workers should be responsible for self-monitoring as well and should report any symptoms to a supervisor immediately. Pairing workers up on the buddy system is also a great way to keep an extra eye on all your workers. Workers should be made aware that personal risk factors can make them more susceptible to heat illness.These include age,overall health,level of acclimatization,alcohol consumption, prescription drugs and the amount of water consumed throughout the day. Symptoms of heat exhaustion include headache; dizziness; weakness; cold,pale or clammy skin; fast or weak pulse; nausea or vomiting and fainting. Not all of these symptoms will necessarily be present if suffering from heat exhaustion. Symptoms of heat stroke include high body temperature (above 103°F); hot, red, dry or moist skin; difficulty breathing; confusion; seizure; heavy sweating; rapid and strong pulse and possible unconsciousness.Heat stroke is the more serious of the two main types of heat illness. Heat stroke can cause major damage to the brain, heart, liver, kidneys and muscles.
  • 9. 9 | Preventing Heat Illnesses at the Construction Site TAKE PROTECTIVE MEASURES OSHA has compiled the following chart of protective measures to take based on the heat index and associated risk level:
  • 10. Heat Index < 91oF Heat Index 91oF - 103oF Heat Index 103oF - 115oF Heat Index > 115oF Risk Level Lower (Caution) Risk Level Moderate Risk Level High Risk Level Very High to Extreme • Provide drinking water • Ensure that adequate medical services are available • Plan ahead for times when heat index is higher, including worker heat safety training • Encourage workers to wear sunscreen • Acclimatize workers If workers must wear heavy protective clothing, perform strenuous activity or work in the direct sun, additional precautions are recommended to protect workers from heat-related illness. • Remind workers to drink water often (about 4 cups/hour) • Review heat-related illness topics with workers: how to recognize heat-related illness,how to prevent it,and what to do if someone gets sick • Schedule frequent breaks in cool, shaded area • Acclimatize workers • Set up buddy system/instruct supervisors to watch workers for signs of heat-related illness If workers must wear heavy protective clothing, perform strenuous activity or work in the direct sun, additional precautions are recommended to protect workers from heat-related illness. • Schedule activities at a time when the heat index is lower • Develop work/rest schedules • Monitor workers closely • Actively encourage workers to drink plenty of water (about 4 cups/hour) • Limit physical exertion (e.g. use mechanical lifts) • Have a knowledgeable person at the worksite who is well- informed about heat-related illness and able to determine appropriate work/rest schedules • Establish and enforce work/rest schedules • Adjust work activities (e.g.,reschedule work,pace/rotate jobs) • Use cooling techniques • Watch/communicate with workers at all times When possible, reschedule activities to a time when heat index is lower. Reschedule non-essential activity for days with a reduced heat index or to a time when the heat index is lower.Move essential work tasks to the coolest part of the work shift. Strenuous work tasks and those requiring the use of heavy or non-breathable clothing or impermeable chemical protective clothing should not be conducted when the heat index is at or above 115°F. If essential work must be done, in addition to the steps listed above: • Alert workers of extreme heat hazards • Establish water drinking schedule (about 4 cups/hour) • Develop and enforce protective work/rest schedules • Conduct physiological monitoring (e.g. pulse, temperature, etc) • Stop work if essential control methods are inadequate or unavailable.
  • 11. 11 | Preventing Heat Illnesses at the Construction Site EMERGENCY PROCEDURES Immediate action should be taken as soon as a worker is observed or reports any signs or symptoms of heat illness. In the event of an emergency, 911 should be called immediately. Workers and supervisors should both be able to give their current location and a description of symptoms to the 911 dispatcher.First aid should be provided to the worker based on their symptoms. For heat exhaustion or cramps, workers should be moved to a cool, shaded area and be given plenty of cool water to drink. Tight clothing should be loosened and ice packs can be applied until the worker is feeling better. If heat exhaustion doesn’t improve or worsens after an hour of rest, the worker should seek medical attention. For heat stroke,call 911 immediately and begin to administer first aid.This includes moving to an air-conditioned area where they can lie down and removing any unnecessary clothing. Cool the body by applying ice packs to the worker’s armpits, groin, back and neck to get their core body temperature down. Alternatives include wetting the skin while fanning air over the body or immersion in cool water or an ice bath.
  • 12. 12 | Preventing Heat Illnesses at the Construction Site HAVE A PLAN They key to keeping your workers safe and preventing heat-related illnesses from occurring at your construction site is to have a written heat illness prevention program as part of your company’s overall policy. The information provided is a great starting point and general guideline for creating a prevention program for your company. AS ALWAYS,WORK SMART, BE SAFE!
