Workplace Heat Safety Tips: Protecting Employees from Heat-Related Hazards

If your worksites operate furnaces or commercial ovens, then heat safety is a priority for worker safety and regulatory compliance.

To ensure adequate workplace heat protection, the following safety tips are recommended:

  • Understanding the importance of workplace heat safety
  • Recognizing the signs of heat illness
  • Identifying potential heat hazards
  • Establishing a heat safety program
  • Providing adequate ventilation and air conditioning
  • Providing training on proper use of personal protective equipment
  • Implementing work and rest schedules/cycles
  • Providing access to cool water and water breaks
  • Training employees on all heat safety guidelines
  • Updating all heat safety measures as needed

Together, these heat safety procedures and tips will provide additional protection for your workers and additional protection for your jobsite in the form of better regulatory compliance.

A Closer Look at Important Workplace Heat Safety Tips

Workplace heat safety is a team effort and requires a comprehensive approach, as heat is invisible and odorless. That approach should include the following:

  • Understanding the importance of workplace heat safety – Heat safety isn’t just an employer’s responsibility, it’s the right thing to do. Every year, heat illnesses affect thousands of workers and cause serious, sometimes permanent or fatal injury.
    The first step for employers is to reinforce the importance of heat safety at every level of the company, including upper management. Safety culture is reflected by company leadership and all the way down to the individual workers who are most at risk of heat injury.
    An easy and inexpensive way to prioritize heat safety is to invest in heat stress management signs, as these remind workers of essential heat safety guidelines and encourage caution. They are also available in bilingual versions to support a bilingual workforce. Heat aware cards also reinforce heat safety awareness and provide workers with up-to-the-moment information on temperature and heat stress conditions.
  • Recognizing the signs of heat illness – Heat illnesses tend to emerge suddenly and progress quickly, so it’s essential that everyone on your worksites recognize the signs and symptoms of heat illness.
    Heat exhaustion and heat stroke present with confusion, slurred speech, excessive sweating, headaches, irritability, nausea and vomiting and, in severe cases, loss of consciousness. When any of these signs are present, it’s up to other workers and supervisors to notice and respond appropriately.
  • Identifying potential heat hazardsHeat safety plans are the guiding document when improving worker protections, and the first step in any workplace heat safety plan is identifying the worksite’s heat hazards. For exterior worksites, pay attention to where sun and shade are present throughout the day. For interior worksites, furnaces, ovens, foundries and any areas with limited air circulation are high heat-risk locations. Safety and heat stress management signage should be installed in these areas.
  • Establishing a heat safety program – Occupational safety plans are the primary safety guidance documents for worksites. However, for worksites with significant heat hazards, it makes sense to take the safety plan a step further and put together a heat-specific safety plan. Heat safety planning should include a list of all heat hazards identified on the site, the safety measures in place to mitigate them, and emergency procedures that should be followed if severe heat illnesses emerge. Once a heat safety plan is put together, managers should immediately implement all safety and training measures.
  • Providing adequate ventilation and air conditioning – Circulating air will reduce the impact of heat and should be present at all cooling stations. Inside, air conditions and air moving fans are recommended. Outside, position cooling stations in areas where air is moving, or install fans inside a tent to facilitate cooling.
  • Providing training on proper use of personal protective equipment – Personal protective equipment (PPE) is a critical layer of protection around chemical, electrical or fire hazards. However, they can cause overheating if worn too long or not worn properly. Heat safety training should include proper use of PPE to ensure it doesn’t result in heat illness.
  • Implementing work and rest cycles – When heat risks are elevated, like during peak daytime temperatures, many employers switch to alternate work rotations where workers spend less time at high-stress, high heat-risk stations and have additional time to rest – or at least have more time at light-duty workstations.
  • Providing access to cool water and water breaks – Regular hydration is a frontline defense against heat stress and should be consumed regularly during periods of elevated heat risk. Employers should ensure all cooling stations have access to cold water that’s replenished as needed.
  • Training employees on all heat safety guidelines – Once your organization has its workplace heat safety measures in place, including a heat safety plan, it’s time to train supervisors and employees on the plan. Training drills and unscheduled inspections will send the message to everyone that the company takes heat safety seriously.
  • Updating all heat safety measures as needed – Your company’s heat safety procedures should be updated and improved upon as potential vulnerabilities emerge in your safety plan. Review your heat safety measures prior to the hot season to ensure your organization is ready to deal with heat stresses. If heat hazards are present year-round, review your safety procedures semi-annually to verify emergency response readiness.

Implementing Workplace Heat Safety Tips Will Provide Protection for Employees

Heat is a difficult hazard to avoid, and it can become intense before anyone takes notice. Fortunately, heat is something that employers can prepare for with proper planning and procedures in place. For the sake of ensuring regulatory compliance and for your workers’ safety, consider implementing these heat safety tips on your worksites.
