A Heat Safety Plan Should Be Part of Every Cement Company’s Operations

A Heat Safety Plan Should Be Part of Every Cement Company’s Operations

Heat Aware , , Comment

Cement manufacturing plants are high-risk work zones. Chemical burns, excess noise, mechanical hazards, falling objects and airborne dust are some of the most common, but there’s another risk for cement companies to account for – heat.

In areas where heat is excessive, it can quickly lead to severe injuries if safety precautions aren’t taken. These precautions are generally simple, but they rely on strong planning and information to work – information like to-the-minute temperature data.

Heat is Always Present in Cement Plants, Making Heat Injuries a Significant Risk

Cement manufacturing plants generate intense heat, some of which escapes into the work environment. If poorly managed, the resulting rise in temperatures may put workers at risk. Further, workers are required to don protective wear that, while safeguarding the lungs, can trap thermal energy and put workers at increased risk of heat-related injury. This risk is higher still in hotter climates, like those along the Gulf Coast.

If a heat injury or illness does occur, it may take one of several forms, but heat exhaustion and heat stroke require the most attention. Here is how each one presents:

  • Heat exhaustion – Heat exhaustion is less serious than heat stroke, but it can quickly develop into a medical emergency. Signs of heat exhaustion include an elevated body temperature, weakness, dizziness, headaches or cramps, changes in mood and reduced urination. Workers experiencing heat exhaustion should receive prompt medical treatment, including transport to a medical facility in serious cases.
  • Heat stroke – Heat stroke is a medical emergency and may result in permanent or fatal injury if not immediately treated. When the body loses its ability to regulate its temperature, heat stroke is the result. As such, heat stroke can cause body temperature to spike in excess of 106 degrees Fahrenheit within minutes. It may also cause profound confusion, an altered mental state, seizures, or loss of consciousness.

Heat is a silent killer, resulting in hundreds of deaths every year. With some basic precautions, though, many of those deaths can be prevented.

A Heat Safety Plan is Recommended for Cement Plants

The upside is that cement companies can plan around heat hazards and minimize their impact on worker safety. OSHA does not require organizations to have a heat safety plan in place, but they can make a big difference. Such a plan should include:

  • The personnel responsible for communicating and enforcing heat safety processes.
  • The location and nature of any heat hazards.
  • What medical facility to contact (and how to contact them) should a heat injury occur.
  • What onsite resources are available should a heat injury occur – and where to locate them.
  • What onsite resources are available to prevent heat injuries, such as cooling and water stations.
  • What measures and resources are in place to monitor temperature data.

A plan like this can be developed and communicated quickly to workers. It’s critical, though, that these procedures are enforced and backed up at the worker level. When a worker suffers a heat injury, the first people to notice are the people he’s working with. With safety plan training, those workers will be better equipped to notice heat injuries and properly respond to them.

An Effective Tool Against Heat Injuries: Easy-to-Carry Thermometers

As an invisible hazard, heat has a tendency to sneak up on workers and safety personnel. It can creep into dangerous territory without anyone noticing, at least not until a medical emergency occurs.

Constant temperature monitoring is the only way to keep an eye on heat hazards, but that can be prohibitively difficult in cement manufacturing facilities. Heat hazards may be present throughout the facility and may develop as work conditions change. The sheer scale of a cement facility adds to this difficulty.

One solution is to empower workers to track temperature data where they’re working. There’s no better way to get location-specific data, and it can be done quickly and inexpensively with the use of liquid crystal thermometers (LCTs).

The crystals inside LCTs respond to changes in temperature, specifically by rearranging themselves and contorting into different shapes. This changes their optical qualities – which we receive as a change in color. LCTs are inexpensive, accurate and can be incorporated into compact, lightweight items.

For example, LCTs can be embedded in TWIC sized heat cards that provide clear data about ambient temperature. Each card can feature additional information about heat injury symptoms or prevention methods. They can also feature the organization’s branding. They can be kept on a lanyard, in a toolbox, or even in the worker’s back pocket.

In this way, workers maintain constant heat awareness and can remove themselves from hazardous conditions as soon as they arise.

Give Cement Plant Workers the Tools to Protect Themselves from Heat-Related Injury

Cement plant workers rely on their company and their safety personnel to maintain a safe workplace. And from a safety standpoint, there’s a lot to consider at cement manufacturing facilities. Don’t forget to account for heat, though, as it’s certainly capable of fatal injury. That means developing a detailed heat safety plan and providing the resources your teams need to protect themselves.

Preparing Your Crew for the Summer Heat

Preparing Your Crew for the Summer Heat

Heat Aware , , Comment

Every year, summer heat kills dozens of workers and injures thousands more. As such, summer heat is a critical safety factor to account for. Heat exhaustion, and its deadlier cousin heat stroke, can produce life-threatening acute symptoms and long-term complications. Also, a single heat injury leaves people more susceptible to future heat injuries, so they’re a high priority risk.

If your crew’s busy season is the summer season, then it’s time to address workplace heat safety. That way, your crew will be ready for any weather they face.

Know the Signs and Consequences of Heat-Related Injury

The best defense against heat injury is attention. By paying attention and responding to the emerging signs of heat illness, the worst injuries can be avoided. Those at elevated risk of heat injury – the elderly and those with high blood pressure – may experience a more rapid and severe onset of symptoms.

There are multiple types of heat injuries, ranging in severity. They include:

  • Heat cramps – Heat cramps are a common first sign of heat injury and are more common in people who sweat heavily. They’re caused by an excessive loss of sodium via sweating and can produce painful spasms in the abdomen or extremities.
  • Heat exhaustion – Heat exhaustion sits between heat cramps and heat stroke in terms of severity. When the body starts losing its ability to regulate its internal temperature, heat exhaustion follows. Signs include headache, dizziness, weakness, nausea, excessive thirst, and reduced urination.
  • Heat stroke – Heat stroke is the most severe form of heat illness and is capable of inflicting fatal injury. In people with heat stroke, internal temperatures are dangerously high, and the body’s sweat-related processes fail. Heat stroke can quickly cause severe, including permanent, injury. Symptoms include loss of consciousness, confusion, seizures and either extreme sweating or no sweating at all. Emergency treatment is required to prevent fatal injury.
  • Rhabdomyolysis – Rhabdomyolysis commonly presents with heat stroke and is characterized by the rapid destruction and breakdown of muscle tissue. It can be caused by many things, including prolonged exertion in hot conditions.
    Rhabdomyolysis is a medical emergency, as muscle tissue releases proteins (myoglobin) when it is destroyed. The myoglobin can reach the kidneys and cause serious damage to them. Symptoms include muscle cramps, weakness, and dark-colored urine. Many people who experience rhabdomyolysis, though, are asymptomatic.

By taking note of the above signs and symptoms, your safety teams will spot heat injuries before they progress from bad to worse.

Create a Heat-Specific Safety Plan

Ideally, heat injuries are prevented, not just treated. And at busy worksites, the best way to prevent injury is to plan for it.

For some industries and major construction projects, safety plans are an OSHA requirement. However, many project managers go a step further and create site-specific safety plans – which often boil down to hazard-specific safety plans. On worksites where heat is a likely hazard, a heat-specific safety plan will improve preparedness should a heat injury occur. This plan may include the following:

  • Temperature data taken from the worksite
  • Provisions for how workers can monitor temperatures in the field
  • Where “hotspots” are likely to emerge
  • How and where workers will be given breaks to recover
  • Where heat-related first aid resources are located
  • What to do when a heat injury does emerge
  • Who to contact if a heat-related emergency occurs – or where to take an injured worker if there is an emergency
  • Assigning who is responsible for enforcing heat safety protocols

Once this plan is in place, it should be communicated to every work team and demonstrated through example by project leadership.

Establish Areas Where Workers Can Rest and Hydrate

Breaks and hydration are necessary for safety purposes, which means a shady, cool area to rest and plenty of water to drink. You can establish break areas with a tent, in a temporary, climate-controlled building, or just a well-shaded spot. Target areas that receive shade for extended periods of time, as these remain cooler throughout the day. High-volume fans are another inexpensive, but effective means of heat control.

Heat illness follows dehydration, so frequent water breaks are important for worker health. Depending on the heat index (a combination of temperature and humidity), workers may need up to 32 ounces of water every hour (a cup every 15 minutes) to maintain hydration. Make sure that there’s enough for every crew member, and that someone is assigned to get more water if necessary.

Keep an Eye on Changing Field Conditions, and Respond Accordingly

Even when the proper safety measures are taken, conditions can get to the point where working safely is too risky to manage. These dangerous conditions can creep up on worksites and safety managers, so monitoring the site’s heat index is a priority.

One way to do this is with cards designed with encapsulated liquid crystal (ELC) thermometers. ELC is made up of crystals that are highly sensitive to changes in temperature. Specifically, they twist and shift as heat increases, changing the way they absorb and reflect wavelengths of light. To us, we see this as a change in color. As heat increases or decreases, ELC thermometers change color, and they’re tiny enough to be incorporated into laminated cards.

If every worker is given one of these cards, which they wear on a lanyard or keep in their pocket – they’ll always be aware of worsening field conditions. ELC thermometers are accurate to within a couple degrees, too, so they can be relied on.

With the Right Safety Measures and Resources in Place, Workers Can Beat the Summer Heat

For many workers, heat is unavoidable. It can be planned for, though, and this goes a long way in preventing heat injuries. Such preparation should include onsite first aid resources, safety personnel, frequent hydration breaks, and heat monitoring equipment, among other measures.

With these policies in place, your teams can avoid a potentially tragic, and certainly avoidable emergency.

What Are The OSHA Requirements for Heat Safety

Heat Aware , , Comment

The Occupational Safety and Health Administration, or OSHA, is the governing body overseeing the implementation of workplace safety measures. It organizes these measures through various regulations, all of which employers need to be concerned with. As of yet, OSHA does not have particular regulations in place for heat safety, but that doesn’t mean employers can slide on protective measures. OSHA’s General Duty Clause requires employers to be aware of and remove recognizable hazards that are likely to cause serious harm or death to their workers. OSHA considers excessive heat, both environmental and labor-induced, to be among those recognizable hazards. As such, it is the employer’s responsibility to account for the heat and take the appropriate steps to neutralize its effects on employees.

OSHA Requirements For Heat SafetyWhat OSHA Recommends

OSHA may not have a regulation dedicated to heat safety, but it has published materials detailing how to best approach it. These materials should be of interest to any employer that wants to manage heat hazards the way OSHA expects, and they sit alongside what a heat stress management system includes on the job itself. OSHA recommends greater levels of awareness and intervention as the heat index climbs. The heat index takes into consideration both air temperature and relative humidity. As humidity rises, the body’s ability to wick off heat using sweat worsens, so it’s more difficult for workers to mitigate heat caused by labor. As air temperature and humidity rise, it is up to the employer to offset the increased danger with additional resources.

Some of the most important points of heat safety, from OSHA’s perspective, include:

  1. Provide workers with a shaded rest area – Once the heat index climbs above 90 degrees, heat illness becomes a real possibility. Lower heat indexes can also be a concern if the worker is outfitted with impermeable protective gear, including gear designed to protect against chemical or biological agents. As soon as the heat index passes the 90-degree threshold, or when workers are expected to don heavy, insulated gear, OSHA strongly recommends employers provide their employees with shaded rest areas. This area should be shaded at all times, so it should be comprehensive enough to keep the sun from intruding at any point of the day. It’s also best to set the rest area up where it will be unexposed to warm breezes, which can accelerate the onset of heat-related illnesses. A shaded tent is an example of an appropriate rest area. Its mobile design and contained environment is ideal for establishing a cool area, regardless of the location. Tents equipped with air conditioners or heavy-duty fans can offer the ideal base for workers in need of cooling.
  2. Provide workers with plenty of potable water – OSHA recommends water that is between 50 and 60 degrees, and between four and six cups of it every hour. Water consumption should begin before the worker notices thirst, as it may be too late to prevent dehydration once the worker becomes thirsty. There should always be drinking water available, so employers must have procedures in place to ensure supplies are replenished with regularity. Workers, and particularly workers who are new to working in the heat, should be encouraged regularly, and firmly, to drink plenty of water. Most incidences of occupational heat-related illnesses occur among inexperienced workers, as they may not be accustomed to working in the heat.
  3. Monitor workers continuously for signs of heat illness – When the heat index climbs above 90 degrees, supervisors should ensure that all heat safety measures are being observed. Shaded rest areas should be utilized, plenty of water should be consumed and other cooling methods taken advantage of. As the heat index climbs even higher, it is imperative that worksites have experts on heat-related illnesses available. These experts should be able to recognize the signs of heat illness right away and know how to administer first aid to workers experiencing symptoms. The expert should also recommend changes to work schedules in response to dangerous conditions. In short, there should be someone at the worksite who will ensure workers are safe and following protocols related to heat. At higher heat indexes, medical facilities should be available within minutes. If they aren’t, then it is the employer’s responsibility to have resources on hand to treat any heat illness that emerges. If the heat index climbs above 115 degrees, or if workers are fitted with heavy, insulated gear for long stretches of time, then additional, significant measures to prevent heat illness must be deployed. This includes physiologically monitoring workers, regularly checking their heart rate, temperature and other vitals that may indicate overheating. Workers should be acclimatized to an extreme environment like this prior to taking on a full workload.
  4. Provide cooling measures, for both preventative and curative situations – When the heat index passes 103 degrees, it’s important that employers consider personal cooling methods. This will protect workers who must remain in the sun for extended periods of time, and workers who cannot access rest areas as often. Personal cooling may be as simple as clothing that has been dampened with water, or something a bit more advanced, like misting stations. Reflective clothing and vests with cooling packs are also effective. If heat illness does appear, then immediate steps must be taken to prevent permanent injury (or death) to the worker. This includes rapid application of wet cloths, transport to a cooled room, administering fluids and immersion in an ice water bath. As this scenario may cause unconsciousness, it is critical that measures are in place to handle an unconscious person.
  5. Pair workers together while they are exposed to heat – The signs of heat illness can creep in slowly and may not be noticed before they become serious. Using a “buddy system” can help worksite managers detect heat illness faster, which may make the difference in keeping workers safe.

Heat-related illnesses are potentially deadly, and it is up to employers to neutralize hazards before they materialize. Adhering to OSHA recommendations will go a long way in doing this as they provide an excellent starting point.

OSHA Heat Safety FAQ

Does OSHA have a heat stress standard?

Not yet. As of September 2026 there is no final federal heat standard. OSHA published a proposed Heat Injury and Illness Prevention rule on August 30, 2024, and held public hearings from June 16 to July 2, 2025, but a final rule has not been issued. Until one is, OSHA enforces heat hazards through the General Duty Clause and its heat National Emphasis Program.

How does OSHA enforce heat hazards without a heat rule?

Through the General Duty Clause, which requires employers to protect workers from recognized hazards likely to cause death or serious harm. Excessive heat is one of them. OSHA also renewed its National Emphasis Program on heat hazards on April 10, 2026, extending it through 2031. The program covers indoor and outdoor work, targets high-hazard industries, and sets heat priority days when the heat index is 80 degrees or higher, when inspectors can conduct heat inspections and ask about heat safety during other inspections.

What does OSHA look for during a heat inspection?

Inspectors want to see that the employer recognized the heat hazard and did something about it. That usually means a written heat illness prevention plan, drinking water, rest breaks, shade or cool-down areas, an acclimatization schedule for new and returning workers, training for supervisors and crews, and a plan for responding to a heat emergency. They may also review injury and illness logs and interview workers. Our guide to heat stress causes, symptoms and prevention walks through the controls in more detail.

Do any states have their own heat illness rules?

Yes. California, Washington, Oregon, Colorado, Minnesota, Nevada and Maryland have adopted their own heat rules, and each sets its own scope and triggers. Texas does not have a state heat standard, so employers in Texas fall under federal OSHA, the General Duty Clause and the National Emphasis Program. If you operate in more than one state, check each state’s current requirements.

Will heat safety products make my workplace OSHA compliant?

No. No product makes a workplace compliant, including ours. Compliance comes from the program: identifying the hazard, putting controls in place, training people and responding when someone gets sick. Awareness tools such as Heat Aware Cards and heat stress management system signs support that program by keeping the heat hazard and the plan in front of the crew, and a heat stress toolbox talk helps reinforce it every shift.

Hydration and Avoiding Heat-related Illnesses

Heat Aware , , Comment

Hydration is the best defense against heat-related illnesses

Heat-related illnesses, most often in the form of heat exhaustion and heat stroke, are serious threats to worker safety. Every year, excessive heat kills dozens of U.S. workers, and incapacitates many more. Although it doesn’t have to be this way because with proper education, monitoring and worker safety procedures, heat illness can be avoided. It’s critical that serious heat illness be avoided on job sites because even if a worker is revived, they can face long-term complications that can affect their quality of life.

Ideally, worksites should be equipped with plenty of educational and reference materials so workers are constantly reminded of necessary precautions regarding heat. It is essential that site managers have this knowledge down pat so they can make sure their crew takes proper precautions when outside temperatures and heat indexes climb to dangerous levels.

A frontline approach to avoiding heat exhaustion or heat stroke is frequent hydration. Hydration will not guarantee workers are safe from heat-related illness, but it will provide a strong measure of protection. This is what proper hydration looks like:

  1. Less than 90 degrees Fahrenheit – No work restrictions or fluid intake measures are required. Intake fluids as needed and rest as needed.
  2. Between 90 and 94 degrees Fahrenheit – Workers should rest 10 minutes out of every hour and take in between 12 and 24 ounces of fluid.
  3. Between 95 and 99 degrees Fahrenheit – Workers should rest between 10 and 20 minutes out of every hour, depending on how strenuous their job is. Fluid intake should measure between 24 and 36 ounces every hour.
  4. Between 100 and 104 degrees Fahrenheit – Rest at least 20 minutes every hour, and more if needed. Take in 36 to 48 ounces of water every hour.
  5. Between 105 and 109 degrees Fahrenheit – Workers should get at least 40 minutes of rest hourly and take in between 36 and 48 ounces of water per hour.

When temperatures rise above 109 degrees Fahrenheit work should only proceed under the watchful eye of Health and Safety professionals.

As outlined above, extensive hydration is needed to maintain safety, and it should be reinforced with clear reference heat cards, heat index posters and the like.

The importance of avoiding heat-related illness

Athletes and workers in demanding, labor-intensive fields, such as construction and landscaping, are most often affected by heat exhaustion and heat stroke. Among athletes and laborers, there is often a sense of powering through the job, even when symptoms of heat exhaustion begin to emerge. This can prove to be fatal and should be strongly discouraged. Instead, the symptoms of heat exhaustion and heat stroke should be constantly checked for, along with making sure there is time for rest in the shade and adequate hydration. Symptoms of heat-related illness include:

  1. Heat exhaustion – Symptoms include excessive thirst, nausea, dizziness, weakness, excessive sweating, decreased urine output, headache, irritability and high body temperature. Heat exhaustion can be triggered by physical exertion in hot and humid weather and is the result of loss of electrolytes through sweating. Sweating pulls both fluids and electrolytes from the body, and they must be replenished to ensure continued cellular function. Most consider heat exhaustion to be a transition step to heat stroke, so aggressive treatment measures should be undertaken if it manifests. Fortunately, with prompt treatment, recovery is promising and rapid. Get the worker to a cool place, have them shed any extra clothing and cool them off with fanning or wet towels. Make sure to give them fluids, but only if they are awake and not confused. Intravenous fluids are an option if the worker is unresponsive.
  2. Heat stroke – Heat stroke produces most of the same symptoms as heat exhaustion, though disorientation and lack of sweating are also present. Heat stroke emerges when the body’s core temperature rises in excess of 105 degrees Fahrenheit, and at this temperature, cellular damage and, by extension, organ failure, is expected in 30 minutes. When the body is stressed with this much heat, proteins inside the cells denature (or lose their physical properties). As a result, the cells lose their structure and leak their contents into surrounding tissue. This can occur throughout the body, so mass organ failure is expected if treatment is not prompt and extensive. Reducing body temperature is the primary goal when heat stroke is present. In fact, it should be attempted before transporting the worker to a medical facility. Move the worker to a cool place and engage in aggressive mechanical cooling. Ideally, the worker would be placed in an ice bath, taking care to monitor the worker at all times, especially if they are unconscious. If an ice bath isn’t available, apply wet, cold towels to the body and head. Intravenous fluid delivery will likely be essential to rehydrate the worker.

Heat stroke should be avoided at all costs. Even if the worker is rapidly resuscitated, serious, long-term complications can emerge. Mortality rates following heat stroke rise dramatically for recovered patients, suggesting that even after recovery, permanent cellular damage is still present and capable of interfering with the body’s normal functions. Research into heat stroke patients has found that functional impairment and loss of independent function are potential outcomes following recovery.

Fortunately, heat exhaustion and heat stroke can be avoided outright if employers take them seriously. Stay educated on heat-related illness awareness and provide plenty of information and hydration options for workers on the job site.
