Proposed New Rules for Workplace Protection Against Wildfire Smoke

Not much is known about the true effects wildfire smoke has on outdoor workers, yet many regions are considering installing new rules to protect workers against associated workplace health hazards. Wildfires generate copious amounts of smoke into the atmosphere which can linger and spread far distances affecting many diverse workplace industries, and those that must work outdoors are directly at risk. Certain complications affecting respiratory and cardiovascular systems are known to be caused directly from smoke inhalation, and protections in the new rules will seek to provide for those ailments. 

Many different components have contributed to the new rules and certain regions have been in discussions for multiple years over the specific regulations to be imposed. Lawmakers have been diligently working with environmentalists, scientists, medical professionals, public involvement, and those predominantly affected to develop succinct rules that can protect those at risk. Certain areas more severely affected by climate change, drought, and dry conditions will continue to increase frequency of wildfires posing additional risks for industries and any employee conducting business outdoors. 

Effects of Smoke Exposure

Smoke exposure can invoke a variety of different complications to the human body, particularly affecting the respiratory and cardiovascular systems of those exposed. Wildfire smoke is different from cigarettes or exhaust due to the variety of different gas combinations and particulate matter. The mix of gasses and fine particulates form from burning vegetation, structures, or other materials. Studies suggest breathing in wildfire smoke can have instantaneous effects on anytype of individual, regardless of health. 

Immediate Symptoms

• Coughing

• Breathing difficulties 

• Stingy eyes

• Dry throat

• Runny nose

• Irritated sinuses

• Wheezing and shortness of breath

• Chest pain

• Headache

• Asthma attacks

• Tiredness

• Accelerated heartbeat

Immediate side effects from smoke inhalation can rapidly degrade a person’s ability to effectively work, travel, or participate in outdoor activities. These symptoms can continue to persist for extended periods of time, even when a person removes themselves from the source of the smoke.

The difficulties when assessing smoke inhalation risks in regards to wildlife smoke is the percentage of pollutant particulate matter. Health effects when dealing with air particulates can range from relatively minor symptoms to more serious long term health effects. The fine particulates are respiratory irritants that can cause persistent coughing, phlegm build up, difficulty breathing, and impacts to the entire respiratory system. These particulates can decrease the body’s ability to effectively remove foreign materials from the lungs, leading to excess bacteria and viral infections. Even people without underlying conditions can experience reduced respiratory activity including lung irritation and pulmonary inflammation. 

Long term exposure to wildfire smoke inhalation has relatively little known data to conclusively make assessments, however studies involving prolonged exposure to severe conditions over several days and weeks suggest a cumulatively negative effect on the lung’s capacity to provide clean oxygen to the body. Difficulties in assessing the effects of wildfire exposures is due to the lack of detailed studies on the general public's reaction to those conditions compared to the studies conducted on wildland firefighters directly in the pathway of dangerous smoke conditions. Gaps in the knowledge also fail to accurately depict the status of persistent health conditions in the wildlife offseason for workers. 

Protections From Wildfire Smoke

The most effective way to prevent wildfire smoke inhalation health effects is by limiting a person’s direct exposure to the elements. The Center for Disease Control has published a variety of tips for the public to avoid developing health complications in the height of wildlife season. 

1. Observe local air quality conditions

1. News and health networks will release warnings and condition updates when there is a wildfire in your area. Take safety precautions by limiting your exposure to the outdoors when under advisory. 

2. Evaluate health guidelines if they are available to your area.

3. Stay indoors and keep indoor air as clean as possible. 

1. Keeping inside air sealed from outside pollutants is almost as important as staying inside. 

4. Use an air filter

1. Air filters will help remove potential harmful particulates from the air you are breathing.

5. Do not rely on dust masks for protection

1. Comfort and dust masks will not protect you from smoke as they are only designed to stop large materials like sawdust. 

2. A typical N95 used for covid will provide some protection if you must be exposed to the elements. 

Proposed rulings for regional safety precautions for employers are based on the Air Quality Index (AQI) tool used by the Environmental Protection Agency to measure air quality. The AQI utilizes a rating system to quantify the probability of danger to the respiratory system and anyone outdoors. The rules outline necessary protections for when the AQI denotes dangerous particulate conditions in the air quality. 

AQI Rules - Rating spans 0 to 500 or higher

0 to 69

1. Air quality is satisfactory and no risk to outdoor exposure. 

1. 69 to 100

1. Air quality is acceptable but may pose certain risks to sensitive individuals or those with underlying conditions. 

2. Wildfire smoke response plan and recommended emergency response measures for workers experiencing any associated symptoms. 

2. 101 to 300

1. Some members of the public may begin to experience health complications and respiratory symptoms, while those with underlying conditions may react more severely. 

2. Provide respiratory protections 

3. Feasible working conditions with necessary precautions 

3. 301 to 500

1. Respirator use for affected workers

2. At least N95 masks for every employee

3. Full workplace respiratory protection program

4. Higher than the AQI

1. An N95 does not offer satisfactory protections, and more advanced respirators are required. 

Wildlife Risks for 2023

With summer shortly beginning across the United States what are the predicted risks for wildfires?

Areas in the western United States prone to severe wildfires include dry regions with adequate amounts of vegetation like California, Washington, and Colorado. The threat between April and June will be very low, but gradually increase with summer temperatures and lack of moisture. 

The peak wildlife season is expected to last between August and September, with some areas to remain under advisory until late November. The 2022 season observed more than 7 billion acres of land burned by wildfires and although 2023 has seen more moisture in certain areas then previously recorded, that statistic will likely remain the same if dry conditions prevail later in the year. 

The Northwest and Rockies observed a dryer than average winter, which means those regions will face a higher risk of wildfires as the snowpack melts quickly with the onset of summer temperatures. Some forecasters are placing the start of severe wildfires season as early as June in some of these at risk areas. Forecasters also released warnings that although many states are unaffected by the direct outburst of severe wildfires, the spread of smoke across the nation can continue to pose long lasting effects and should be taken seriously. 

America’s Tornadoes are Evolving

In the last few weeks a flurry of tornadoes devastated many regions in the midwestern United States.These storm cells left scientists and the communities wondering why tornadoes seem to be increasing in frequency, devastation, and expansion across the United States. Peak tornado season lasts between March and June with approximately 70 percent of yearly storm cells being recorded during those months. However, as a warming climate continues to modify atmospheric conditions scientists are observing certain changes in the aspect of tornado patterns and basic formation. 

The 2023 season has already observed five times reported preliminary tornado reports than the average between 1990 and 2010. The month of January alone had an astounding 168 reports of tornado storm cell activities across the United States. 

While it is still too early to definitively relate climate change to increased tornado activities, scientists are able to correlate some adverse side effects to the subtle evolution of tornado size, span, and frequency as they continue to wreak havoc across the United States each year. 

Understanding Tornado Patterns

Tornadoes are a rapidly rotating column of air that extends from a thunderstorm cell system in the atmosphere to the ground. Tornadoes become visible as they form a condensation tunnel of wind that collects water droplets, dust, and debris. Some tornadoes have been recorded with wind speeds of more than 300 miles per hour, completely destroying anything in their path. These storm cells can be some of the most dangerous and destructive weather phenomena, responsible for countless deaths and economic damages each year. 

Tornadoes occur predominantly in the midwestern United States, but other areas of the world that experience them include Argentina, Bangladesh, and various reports on the other continents. The United States records about 1,200 tornadoes every year, however average reports overtime are somewhat inconsistent because official records only date back to 1950 and recording methods have changed overtime. 

The media often refers to an area of the United States known as tornado alley when discussing these deadly storm cells and their typical range across the United States.Although the region is a relatively common for tornado activities, the idea of “tornado alley” can be somewhat misleading.

Tornadoes have been reported in all fifty states, and many violent tornadoes have occurred outside of “tornado alley”. In the cooler months of the year tornadoes are more likely to affect the southeastern states, while the southern central plains regions are more at risk in the warmer months between May and June, and the northern plains during early summer months. 

Environmental Trends Affecting Tornadoes

To understand how environmental conditions may be affecting tornado storm cell development and resulting damages, meteorologists have been researching trends in their parent strom cell development. The scientists have been closely observing how changes in atmospheric humidity, temperature, and jet stream cycles may affect storm cell formation. 

Most tornadoes in the United States form from an uncommon supercell thunderstorm system which requires moist warm air to form close to the ground and a strong wind shear. The system requires a strong vertical wind shear caused by changing wind speeds and direction closer to the ground to draw the warm moisture up into the atmosphere. The air begins to spin cyclonically as it lifts off of the ground and continues to narrow and increase its cyclonic speed as it begins to form a menacing funnel cloud. The funnel and rotating system are the first indication of a potential tornado, but are only classified as such if they actually touch down on the ground. 

Factors Affecting Tornado Patterns 

• Increased heat and humidity in the atmosphere

• Modifications to the jet stream

• Larger and more frequent supercell thunderstorm systems

Since scientific data is fairly limited and inconsistent, scientists cannot definitively identify long term changes in the storm cells over time. They have described that we are currently in an “experimental” phase studying how tornadoes are evolving, and they can only hypothesize what the future will entail. 

The Future of Tornadoes

As warming surface trends, associated with ongoing climate changes, continue scientists have identified possible modifications to the patterns and formation of tornado storm systems as we have observed over the past 70 years. While long term predictions are not possible due to the lack of consistent and historical data, preliminary conclusions and warnings can be formulated. 

Meteorologists have already recorded an increase in the size and frequency of many supercell tornadoes, as damages have continued to surpass millions of dollars in economic losses each year. Continued expansion of industrial and residential development in at-risk regions has contributed to the increased death toll related to tornadoes in the past decades. Another factor is the increasing spread and range the storms are beginning to acquire, as unprepared regions are exposed to the severe risks associated with tornado development. 

Droughts and atmospheric conditions have resulted in fewer deadly tornadoes in states like Texas, Louisiana, Oklahoma, Kansas, South Dakota, Iowa, and Nebraska. A dangerous tornado developed just last month in New Jersey leaving multiple people dead and more continue to appear in states outside the tornado alley region. The southeastern states have a long wind shear that forms the necessary conditions for tornadoes when combined with increased atmospheric temperature and humidity contributed by climate change. The necessary conditions may suggest the range of tornadoes will continue to expand to bordering states previously at a lower risk to these kinds of natural disasters. Meteorologists also suggest supercell thunderstorm formation will likely shift toward later winter and early spring months rather than summer and fall as seasonality is also affected by climate changes. 

There are many uncertainties associated with how and where tornadoes continue to evolve, but scientists are undoubtedly sure there will be continued increases in devastation, loss of life, and economic damages. The United States population has almost doubled since 1950 and increased development across tornado alley and the east coast, suggesting tornadoes are more likely to affect more people than ever before. 

Train Derailment in Ohio Threatens State’s Environmental Health

A massive ecological disaster is currently underway in East Palestine Ohio after a severe train derailment releases a variety of different chemicals into the environment. Scientists have been able to identify several of these chemicals released from the train cars including vinyl chloride, butyl acrylate, and isobutylene. 

Health officials are on high alert because many of the harmful chemicals have been known to cause a variety of harm to human health including irritation, breathing difficulties, cancer, and eye damage. The alarm continues to rise as the full breadth of the disaster continues to unfold, raising major concerns about the severity of exposure and contamination resulting from the incident. 

After the initial derailment of the 150 car freight train occurred, authorities decided to burn some of the spilled chemicals to avoid any potential explosions. The chemical burning has sparked additional concerns regarding human and environmental health for the greater portion of eastern Ohio, as the contaminants have now been observed entering the local atmosphere and essential resources like waterways and nearby farms.  

5 Toxic Chemicals Identified Around Derailment

Residents of the Palestine Ohio area have been told it is safe to return home after the initial assessments of the impacted area, however questions still remain over the extent of exposure to the region’s resources and additional safety concerns surrounding the chemical burning. Scientists are working to determine the level of exposure to the soil, air, and water. They have already been able to identify at least 5 different contaminants released by the train derailment. 

1. Vinyl Chloride: This compound is a known carcinogen, observable as a colorless flammable gas used to make polyvinyl chloride (PVC) components. PVC is the plastic material used in many different types of packing materials, electronics, medical supplies, and construction products. Extended exposure to vinyl chloride can result in drowsiness, disorientation, extremity numbing, nausea, and eventually cancer. This chemical is also a culprit of severe eye and skin irritation, among many of the initial reports from affecting individuals. Vinyl chloride has also been recorded causing extensive liver damages to those with long term exposure able to seep into soil and pollute groundwater resources. 

2. Butyl acrylate: This colorless liquid chemical is also used to produce various types of plastics, polymers, resins, and material coatings. Butyl acrylate is colorless with a fruity odor causing irritation to the eyes, skin, and respiratory tracts after long exposures. 

3. Isobutylene: A colorless gas utilized in plastic production for packing materials and resins. Exposure to isobutylene causes dizziness and headaches.The shipping company transporting this company reported in an inventory briefing that the cells carrying this chemical had no breaches, although it has still been observed in the scientist’s environmental assessment surveys. 

4. Ethylene glycol: A synthetic compound used in components of paint, ink, hydraulic brake fluid, and antifreeze compounds. Exposure to ethylene glycol has been recorded causing irritation to eyes, skin, and upper respiratory tracts. 

5. Ethylhexyl acrylate: This colorless liquid is used to produce plastics and polymer compounds. Any person exposed can experience irritation to their eyes and skin as well as nausea and sore throats. 

Experts Criticize Disaster Response

Most of the country has been kept in the dark regarding the massive derailment, and many experts are now highly skeptical concerning the actual response from county officials and site surveys. The derailment was overshadowed in the news by sightings of rogue balloons thought to be of Chinese origin over the continental USA, and the superbowl. As more information and public highlighting of the events happening in the Ohio town reach the rest of the country, people are demanding more cohesive explanations regarding how officials are handling the spill. 

So far the conclusions are unsure if officials have done enough to study the effects and potential concerns for immediate and long term impacts the chemical spill could pose to human and environmental health. Evidently there has been a lot of testing and safety discussions since the initial accident, however there has not been any formal reports outlining the comprehensive actions taken to address the contamination concerns and consequences. 

Other expert scientists have also drawn concerns to the potential pollutants that may have been created as a byproduct of the derailment and fire. When some of the identified chemicals are burned they can produce byproducts known as dioxins which are extremely harmful and toxic substances. 

Ohio’s Environmental Protection Agency has stated they will be continuing to monitor and survey the quality of Palestine’s air, soil, and water however they have not identified if they will also be testing for the harmful chemical byproducts adding to further criticism. 

The dioxins are heavy sticky compounds able to settle on people’s properties and tracked inside their homes, creating health hazards after being inhaled or ingested. These toxic compounds by products also do not break down easily and can sometimes persist for decades.

Environmental Damages

Initial estimates have been updated to suggest the freight train derailment is responsible for more than 44,000 animal deaths. The Ohio Department of Natural Resources (ODNR) estimates the deaths account for more than 38,000 minnows, plus more than 5,000 additional species that include fish, amphibians, crayfish, and macroinvertebrates. 

Shortly after the derailment officials declared it unsafe to enter waterways in the area unless prepared with specialized protective gear and equipment. Residents reported hundreds if not thousands of fish washing up on the shores of the rivers and streams further downstream from the incident, although officials have observed fish returning to the initial areas closer to where the incident happened. 

Hazardous trains are also required to be fitted with specialized automatic braking systems that would allow trains to brake faster potentially reducing the extent of damage a derailment can cause. Companies are always looking for ways to add more cars to their trains, inadvertently increasing the risk of derailment.

Mauna Loa Volcano Awake Almost 40 Years

Mauna Loa Volcano, located on the Big Island of Hawaii, has been awake for nearly two years, and has finally erupted in late November.

This imposing volcano is one of the most active in the world and its activity reveals fascinating insights into geology and Earth's shifting landscape.

In this article we explore what an 'awake' Mauna Loa means for locals, scientists and hikers alike.

Mauna Loa Volcano: Exploring Its Recent Activity

Mauna Loa is the largest volcano on Earth, located in Hawaii.

It has been active since its formation thousands of years ago and continues to show signs of activity today through periodic eruptions.

Over the past two years, Mauna Loa has awakened again with a series of small earthquakes that have caused concern among scientists and residents alike. Prior to this activity the last eruption was not since 1984. 

From December 2018 to July 2019, there were 619 small magnitude earthquakes detected near Mauna Loa Volcano’s summit region (at depths less than 5 km).

Scientists believe these quakes are related to magma movement within a shallow magma reservoir close beneath the surface—an indication that new eruptions were likely years down the road, and it finally happened.

What makes this event so interesting and noteworthy is not just its size but also its duration; most seismic swarms associated with volcanoes typically last only weeks or days whereas this one has lasted an entire eight-month period.

The fact that seismic activity continued for such an extended time frame tells us something important: it was likely driven by pressure from large amounts of trapped gas rather than rising molten rock inside a shallower chamber below ground level.

The eruption occurred as pressurized gasses like carbon dioxide rose with the molten rock fast enough to the surface. The expanding gasses and materials lead to big explosions as the energy is rapidly released, sometimes in spouting lava plumes. 

As part of ongoing monitoring efforts, Hawaiian Volcano Observatory (HVO) staff took measurements several times during April 2020 showing increases in sulfur dioxide gas emissions at both Kilauea Summit and lower East Rift Zone vents, as well as changes in temperature consistently throughout those locations, indicating flow pathways which connect distant regions across multiple areas spanning tens of kilometers .

This data reveals that pressure is building inside the volcano to critical rates and future eruptions could occur relatively quickly until the molten materials are dispensed.

Understanding how volcanoes behave requires lots of data analysis compiled from various sources, including remote sensing technologies such as satellites equipped with infrared cameras able to detect heat radiating off the landscape for potentially hazardous hot spots. Field observations closely study features occurring in the surroundings using ground-based instrumentation to track and measure subsurface conditions. The data surveys atmosphere pollution particles in order to assess impacts on the environment to manage land usage for safety purposes. Gathering observations allow for risk analyses to proactively protect affected communities from any future disaster scenarios and identify signs of a possible imminent threat posed to nearby populations.

Mauna Loa's recent awakening provides valuable insight into predicting volcanic behavior: • Insight into pressurization levels behind quakes linked to specific movements happening in deeper chambers, providing better identification strategies for gauging levels of risk in the front-end model. Better identification strategies will aid emergency communication, accordingly helping avert disasters if spotted early enough.

Challenges Facing The Monitoring Of A Restless Giant

Scientists have been closely monitoring Mauna Loa for the past two years, as its state of unrest signaled potential eruptive activities. 

The volcano is located on Hawaii’s Big Island and rises 13,680 feet above sea level.

As one of the world’s most active volcanoes, its activity can cause significant disruption to communities living nearby or even downwind from it.

Here are some of the challenges facing scientists and other authorities as they monitor this restless giant:

1) Inadequate Resources – Monitoring such an active volcano requires constant surveillance including ground deformation measurements, seismic monitoring equipment, aerial photographs and real-time satellite imaging to identify possible eruptions before they occur.

Unfortunately, these efforts require substantial financial resources that many cash-strapped governments lack; consequently, dangerous situations may go unnoticed until it is too late for action.

2) Difficult Accessibility – Many parts of Mauna Loa are quite remote and difficult to access quickly by personnel when necessary, such as during earthquakes or volcanic eruptions when reliable data must be collected quickly without endangering anyone involved in the mission.

This limitation not only makes monitoring more challenging but also results in inaccurate information being captured due to longer response times, which ultimately leads to false alarms that could potentially result in unnecessary evacuations and widespread panic among populations near potential hazards caused by geological events still happening deep underground in off-site locations.

3) Hazards To Personnel – While measuring Mauna Loa’s earthquake activities, seismologists often have to come close enough to place their recording instruments around lava fields while running current risk assessments on potential present dangers. The high risk environment not only involves themselves but also residents living within areas perceived at harm because of possibly misplaced predictions during geophysical studies. 

These are the reasons why people get paid large salaries to get up close to the volatile volcano, doing what others wouldn't dare try anyway. Many tourists travel to Hawai’i to see the volcano, getting extremely close to the dangerous lava fields despite countless warnings now visible everywhere. Increased global attention and foot traffic have made this process perhaps even more risky than usual when confronting unpredictable forces beyond human control.

Officials have established barriers and road closures to prevent people from wandering into unstable areas, and geologists are constantly monitoring ongoing activities. Already the eruption has experienced many changes and its lava is slowly expanding down its slopes towards roads and other infrastructure. 

4) Technology Limitations

- A common challenge faced by those tasked with studying any natural phenomenon occurs when inadequate technology fails to get accurate readings from volcanic emissions floating through air as conditions greatly change over short periods.

Volatile changes require advanced tools and techniques to obtain reliable quantifications.

Untrustworthy data might disrupt communications causing mistaken decisions to result in serious delays and unfavorable outcomes despite the official's best efforts.

Hurricane Ian’s Impact Lingers Amidst Climate Change Implications

Hurricane Ian quickly developed into one of the deadliest hurricanes to hit Florida since 1935, and one of the worst natural disasters in recent years for the United States. Damages from the hurricane are still being evaluated with early estimates totaling more than $60 billion USD alone in damages to infrastructure and properties. This large category 4 hurricane slammed into the Florida coast toward the end of September resulting in significant coastal damages, inland flooding, massive runoff, and large community displacements. Florida experiences many hurricanes each year, but it is now clear that the severity of the storms is increasing as they are exacerbated by the effects of climate change. 

Hurricanes are a natural aspect of the Caribbean and Gulf of Mexico geography, as conditions in late summer and early fall often generate cyclonic storm cells. A majority of south Florida lies at or below sea level putting many areas at increased risk for minor swells and ocean surges, regardless of storm activities. Florida has invested significant federal and state funds into coastal defense barriers like sea walls, sand dunes, foundation fortifications, and emergency aid response programs. These efforts seem to mitigate many damaging effects, but their effectiveness continues to wane as warming ocean temperatures increase the intensity of these Atlantic storm cells.

Climate change has a variety of negative effects on Earth, specifically intensifying the strength and frequency of destructive storm cell activities. Warmer coastal waters increase surface evaporation, rapidly accelerating hurricane wind speeds and the overall strength of the hurricane. Factors like warming climates, more intense storms, and continued development along the coast of at-risk regions like Florida have also increased the susceptibility of people and infrastructure to extensive storm damage. 

President Joe Biden addressed the nation after surveying the damages of the fierce storm, highlighting its similarities to many other significant natural disasters affecting other regions of the country. He indicated how climate change is responsible for many of the extensive damages caused by this storm, the fires in the midwest, and water shortages on the west coast. The increasing vulnerability of many regions affects more than the durability of the infrastructure, also implicates community health and long-term safety. 

As the aftermath of Hurricane Ian continues to be surveyed, it is clear this storm has impacted a multitude of resources, regions, and people across Florida. Many of Florida’s main waterways are now filled with contaminated pollution as a result of the upstream storm surge inundation and coastal runoff. Organic matter, chemical pollutants, and refuse washed off the land from torrential precipitation leading to additional negative environmental impacts. Environmental scientists suggest the pollution could damage aquatic ecosystems posing short-term dangers to human and resource health, while also subjecting these fragile ecosystems to additional long-term challenges. 
With the increasing intensity and frequency of storms like Hurricane Ian, similar events are likely to become more normal in the future. For at-risk regions, preparing the necessary infrastructure and response teams is vital to adequately handle estimated damages. These damages include factors impacting infrastructure, human health, environmental well-being, and long-term effects. Over the past decade, the United States has already had multiple examples of these effects as climate change continues to increase natural disaster intensities and frequencies.
