Increased Risk of Work Safety Accidents During Extremely High Temperatures
1School of Government, Nanjing University, Nanjing, China.
Summary
Extreme heat significantly increases work safety accident risks by 18.7%. This highlights the need for urban adaptation strategies to mitigate heat-related workplace dangers.
Area of Science:
- Environmental epidemiology
- Occupational safety
- Climate change impacts
Background:
- Workplaces face increasing extreme heat due to global climate change and urban heat island effects.
- The precise risk of work safety accidents linked to extreme temperatures is not well understood.
Purpose of the Study:
- To quantify the relationship between extreme heat and work safety accidents in Chinese cities.
- To identify specific types of accidents and geographical regions most vulnerable to extreme heat.
Main Methods:
- Utilized an environmental epidemiology approach.
- Analyzed data from Chinese cities to assess temperature-heat exposure and accident occurrences.
Main Results:
- Exposure to extremely high temperatures correlated with an 18.7% rise in work safety accident risk.
- Low-severity, road transport, and vehicle accidents were particularly susceptible.
- Regions in temperate monsoon and tropical/subtropical monsoon zones showed increased vulnerability.
- An estimated 1% of work safety accidents were attributable to extreme heat.
Conclusions:
- Extreme heat poses a significant risk to work safety, especially for certain accident types and regions.
- Findings underscore the necessity for enhanced urban management, adaptation strategies, and preventive measures to address climate change-related occupational hazards.

4.4K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

7.7K
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Concreting at elevated temperatures accelerates the hydration process, leading to quicker setting but potentially reducing the long-term strength of the concrete structure. Additionally, low air humidity fosters rapid moisture loss from the concrete, resulting in reduced workability, pronounced plastic shrinkage, and a higher likelihood of crazing.
Mitigating the heat increase in concrete can be economically achieved by shading aggregate stockpiles to prevent heating from solar radiation,...

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
