Advanced Microclimate Monitoring for Safety in Petrochemicals

Advanced Microclimate Monitoring for Safety in Petrochemicals

In the petrochemical industry, where safety margins are as thin as the chemicals are volatile, personal protective equipment (PPE) plays a critical role. Yet, this essential gear, while providing necessary protection from chemical exposure and extreme conditions, can also create significant hazards. A key challenge is the formation of microclimates beneath the protective layers, which can jeopardise both the health and the efficiency of workers. Advanced monitoring technology offers promising solutions to mitigate these risks and enhance overall safety and productivity.

What are microclimates?

Microclimates are small areas where atmospheric conditions dramatically differ from the surrounding environment, such as in gardens, parks, valleys or urban areas. Similarly, workers wearing heavy, insulated suits and respirators can inadvertently generate their own microclimates. These microclimates, created by PPE, present significant challenges that must be addressed.

Imagine a worker wearing a thick, chemical-resistant hazmat suit, labouring near large distillation columns where temperatures are already elevated. The suit, while shielding the worker from hazardous chemicals, traps body heat and moisture, effectively creating a ‘personal sauna’. This localised heating effect can drastically raise a worker’s core body temperature, leading to discomfort and, more critically, health risks.

PPE, such as heavy suits and full-face respirators, are designed to block external contaminants but do little to accommodate the body’s natural cooling processes, such as sweat evaporation. In environments where external temperatures can soar, this gear can become less of a shield and more of a burden, resulting in immediate and far-reaching consequences.

What are the health impacts of microclimates caused by PPE?

The health implications of these microclimates as a result of PPE can be severe. Workers facing prolonged exposure to elevated temperatures can experience heat stress. According to the Occupational Safety and Health Administration (OSHA), thousands of workers suffer from serious heat-related illnesses annually. These numbers can be particularly high in environments like petrochemical plants, where PPE-induced microclimates are common.

Heat stress can rapidly deteriorate a worker’s health, leading to a range of symptoms that can progress from initially mild symptoms, such as dizziness and muscle cramps, to severe medical emergencies like heat exhaustion and heatstroke. Heatstroke is not just a medical emergency but a signal of systemic safety failures, often resulting from unrecognised or unmitigated heat stress conditions. 

If not promptly addressed, these conditions can have lasting health effects or even result in a fatality. For example, at a petroleum refinery in Louisiana, a tragic incident claimed the life of a 45-year-old contract worker who was cutting piping while wearing a chemical-resistant suit and multiple layers of clothing. The ambient temperature during the incident was 28°C / 82.4°F, but the increased heat stress was exacerbated by the protective gear. 

This event led to the US Department of Labor’s OSHA citing the company for a serious violation: specifically for not implementing an adequate heat management programme. OSHA’s action reflects the critical need for rigorous safety protocols in handling PPE in environments like petrochemical facilities, where the protection offered by such equipment can inadvertently increase the risk of heat-related ailments. 

The rapid onset of heat stress can catch workers off-guard, particularly in environments where microclimate conditions are not actively monitored. Additionally, the cognitive effects of working in intense heat and their impact on overall worker safety are not to be underestimated. 


The safety impact of microclimates

According to a recent study, workers suffering from heat-induced stress may experience diminished concentration, slower reaction times and impaired judgement. This cognitive impairment can lead to errors in critical, high-risk activities. For example, slower reaction times might delay the shutdown of a reactor in an emergency, escalating a potentially controllable situation into a hazardous event. 

Similarly, impaired judgement could lead to incorrect handling of chemicals, resulting in spills or accidents that endanger the entire facility.

To determine the effects of temperature on workplace injuries, researchers at the University of California Los Angeles (UCLA) compared over 11 million California workers’ compensation claims from 2001 to 2018 alongside detailed local weather data. Their research found that, on days with temperatures above 32°C / 89.6°F, there was a 6% to 9% surge in the likelihood of injuries compared to cooler days. In addition, when temperatures exceeded 37°C / 98.6°F, the possibility of injuries increased by 10% to 15%.


The impact of microclimates on productivity

The impact is equally stark from a productivity standpoint. When temperatures range from 24 – 26°C / 75.2 – 78.8°F , there’s a notable dip in output, escalating significantly as temperatures rise to 

33 – 34°C / 91.4 – 93.2°F, where a worker’s capacity can drop by half. Looking ahead to 2030, with a predicted global temperature increase of 1.5°C / 2.7°F, an estimated 2.2% of global working hours might be lost to heat stress, translating to an economic downturn of approximately $2,400 billion globally. 

When employees are working in direct sunlight, consequences can intensify, increasing to a 3.8% loss in productivity hours, equating to 136 million full-time jobs. This projection is not only a signal for urgent adaptation in labour and health policies but also a call to enhance workplace safety through innovation. Modern heat management strategies and improved PPE designed to mitigate the severe impact of heat stress are needed. 

While PPE is indispensable for worker safety, effective microclimate management strategies are urgently needed in petrochemical environments and beyond. Recognising the dangers posed by microclimates, the next logical step is to look towards proven strategies to manage them effectively to ensure workplace safety.

How to manage microclimates in the workplace

To combat the dangers posed by microclimates effectively, several strategies can be deployed:

Adjusting work-rest cycles 

Implementing more frequent breaks or rotating shifts during the hottest parts of the day can help manage exposure to high temperatures. During these scheduled breaks, it’s important that PPE is removed to allow the body time to cool. 

Improving PPE design

Innovations in PPE, such as using materials that enhance breathability and dissipate heat more efficiently, can significantly reduce the risk of heat stress. Manufactured from a highly breathable material, a study found the Eagle Synergy Suit, designed for firefighters, exhibited 62% less sweat absorption in comparison to two other market-leading suits. Such material choices ensure the risk of dehydration and heat stress is minimised while keeping the user safe.

Localised cooling zones

Setting up cooling stations with mist fans or air-conditioned rest areas provides workers with opportunities to reduce their body temperature between tasks. According to a study by the CDC, access to air-conditioned spaces can reduce heat-related mortality risks by about 66%, compared to those without such access.

While the strategies mentioned are effective, companies can elevate their microclimate management by leveraging advanced technologies that ensure precision and safety under the most challenging conditions. The ability to use real-time physiological monitoring through cutting-edge solutions is revolutionising the approach to these long-standing issues.

Monitoring microclimates

Different workers, varying by age, experience or physical condition, have different personal risk factors when exposed to heat, leading to varied reactions in identical environments. That’s why it’s important to monitor individual physiological responses, rather than just environmental conditions. For example, a veteran worker might tolerate higher temperatures more comfortably than a new recruit, who could be more susceptible to heat stress and fatigue.

Implementing real-time, personal, physiological monitoring can significantly mitigate the risks of microclimates. These wearable solutions use sensor technology to monitor key indicators, such as core temperature, heart rate and physiological strain, in real-time. This provides a comprehensive understanding of each worker’s individual physiological response in environments where microclimates pose a severe risk. 

For instance, implementing wearable technology in a petrochemical facility can alert safety personnel if a user’s core body temperature exceeds safe limits during a routine maintenance operation in a poorly ventilated space. This prompt allows for swift intervention, preventing severe heat-related illnesses. As it is monitoring the individual’s physiological response, this can be an effective alarm long before the user is even aware they’re at serious risk.

Implementing real-time physiological monitoring technologies is a crucial step in managing microclimate risks effectively. These wearable sensors provide not only continuous data but also critical, timely interventions in extreme environments.
