Predictive Analysis Research for Workplace Job Risks and Burnout of Public Health and Safety Inspectors Amid the Global Climate Crisis

1. Introduction

The climate crisis is significantly exacerbating occupational risks for Public Health and Occupational Safety Inspectors (PHOSI). Rising global temperatures and the increased frequency of extreme weather events expose inspectors to heightened levels of heat stress, air pollution, and other environmental hazards. These adverse conditions not only pose immediate physical dangers but also contribute to long-term health issues, including chronic stress and psychological burnout [1]. Traditional risk assessment methods, which are often reactive, may not suffice in addressing these evolving challenges; therefore, there is a pressing need for proactive, data-driven approaches to anticipate and mitigate these risks [2]. Predictive Analysis Research has been used for the first time as an innovative method for analyzing the dynamics of workplace job risks and burnout of public health and safety inspectors amid the global climate crisis and modeling relational qualities, working situations, and workplace environments, accuracy metrics to high burnout and low job satisfaction rates [1,2]. The climate crisis is a recent global threat affecting the lives of common people and deteriorating society's economy. Stress-management resources, a supportive work environment, and opportunities for professional development and self-care are all critical components, especially for the PHOSI [3,4]. The climate crisis has had a substantial impact on the occupational environment, creating extreme changes in weather patterns and contributing to the depletion of our natural phenomena, weather events, and lack of sources [5,6]. These issues can have a significant impact on public health, hygiene, safety and sanitation inspection abilities [7,8]. It has been necessary to adopt different intrusive strategies to control the adverse effects on public health and safety due to the properties of this global climate crisis [7]. Adherence to existing norms and practices, particularly in areas such as professional job satisfaction and risks [9], is critical in limiting the dangers of environmental climate change and crisis on workplace safety and contributing to the depletion of our natural phenomenon's weather events and sources [10,11]. These factors can greatly affect public health, public hygiene, and the safety of the population globally [12]. Considering the scope, it is challenging to have an analytical study and deep understanding based on real situations adhering to existing regulations and practices; methods can be used to address a variety of public health strategies [3,8,11]. Data can also be included for potential behavior changes as reports of new guidelines, reports, and government instructions for appropriate occupational practice are being developed, particularly in areas such as extreme weather events and water resources management [11,13]. Digital tools, such as machine learning and AI predictive-driven methods, must be developed for setting parameters, including prevention rates and epidemiology data [14], and are crucial in mitigating the risks of the environmental climate crisis on occupational safety and hygiene, and air pollution dust [15], associated with the quality of life of employees and cyber threats correlated with ethical concern [16,17]. Artificial intelligence (AI), and Machine Learning (ML) advancements can improve workplace safety by analyzing historical data and real-time environmental inputs. AI-driven predictive models can forecast hazards, assess inspector burnout, and implement preventive measures before incidents occur [18]. AI can reduce occupational burnout by automating repetitive tasks and providing decision support, offering personalized well-being assessments and stress management recommendations for mental health initiatives within organizations [19]. In light of these developments, this research proposes developing an integrated AI model designed to analyze, predict, and mitigate hazards faced by PHOSI. The model will leverage historical occupational data, real-time environmental monitoring, and workforce health indicators to provide personalized risk assessments [1,16]. By shifting from reactive to proactive safety measures, this approach aims to enhance inspector safety, reduce burnout rates, and inform policy interventions for improved workplace resilience [20]. AI-driven predictive analytics can enhance workplace safety and employee well-being by proactively safeguarding PHOSI, minimizing hazards, and mitigating burnout-related workforce attrition [21]. Climate change is causing increased occupational safety and health risks due to frequent and severe heat waves, resulting in heat-related illnesses [3,22]. The International Labour Organization (ILO) warns of heatstroke and exhaustion. Additionally, climate change intensifies extreme weather events, disrupting workplace operations and causing potential accidents and injuries. Air pollution, exacerbated by climate change, introduces additional health risks, posing new health risks in the workplace [17,22]. In summary, climate change exacerbates existing workplace hazards. It introduces new risks, necessitating proactive measures to protect worker health and safety. Occupational burnout among health inspectors, exacerbated by long hours, high-risk environments, and inadequate training, has been a significant concern during the COVID-19 pandemic [9,23]. Excessive workloads and poor working conditions can reduce job satisfaction. A positive work environment, backed by organizational support, is crucial for mitigating burnout and enhancing employee engagement, productivity, and commitment [12,23].

Addressing burnout requires organizational strategies that focus on improving working conditions, providing adequate support, and ensuring a balanced workload. Implementing such measures can increase job satisfaction and reduce psychological stress among PHOSI. The aims and the scope of this research are to first time give a crucial, useful tool for predictive innovative methods and models to calculate and analyze assessment for the workplace job risks and burnout of PHOSI also extended to all healthcare workers prevention and metrics amid the global climate crisis.

3. Materials and Methods

3.1. Methodology

Predictive Analytics in Occupational Health

Machine learning (ML) models have shown promise in occupational health, particularly in predicting burnout and identifying patterns in accidents. Supervised techniques like gradient-boosting classifiers have been effective in predicting burnout among nurses, with a 75.8% accuracy rate [24]. Unsupervised methods, however, can identify hidden structures and risk factors in workplace accidents, enhancing safety; ML approaches have also been used to predict mental health conditions, including burnout, by analyzing data from electronic health records and wearable devices [25]. These predictive models can facilitate early intervention strategies, potentially mitigating the adverse effects of psychological stress in the workplace [26]. Implementing both supervised AI and unsupervised ML techniques can lead to proactive interventions, ultimately improving worker well-being and safety.

3.2. Data Collection

In this study, we employ a comprehensive secondary data analysis collection strategy encompassing three primary sources:

We will conduct surveys to assess PHOSI workplace risks, burnout symptoms, and working conditions. The survey will include validated instruments such as the Maslach Burnout Inventory to measure emotional exhaustion, depersonalization, and personal accomplishment. Previous studies have indicated significant levels of burnout among public health inspectors, with reports showing an increase from 38.7% in 2019 to 73.7% in 2021,[1,4,27]. This underscores the importance of capturing current data on PHOSI well-being.

Real-Time Environmental Data: To assess the impact of environmental factors on inspectors' health and safety, we integrate real-time data from reputable sources. The National Oceanic and Atmospheric Administration (NOAA) provides real-time atmospheric and oceanic data through its extensive network of satellites and weather stations,[28]. Similarly, NASA's Earth Observing System Data and Information System (EOSDIS) offers access to near real-time Earth observation data, including air quality indices and land surface temperatures,[29]. Additionally, data from Internet of Things (IoT) sensors deployed in various workplaces utilized to monitor parameters such as ambient temperature, humidity, and pollutant levels.

Historical Workplace Incident Data: Analyze archival records to examine past workplace injuries, documented cases of burnout, and incidents related to climate-induced risks. This will involve reviewing incident reports, occupational health records, and climate-related event logs. Access to databases such as NOAA's National Centers for Environmental Information (NCEI) will facilitate the retrieval of historical climate data pertinent to our analysis [29,30]. By correlating these historical data with current survey responses and real-time environmental inputs, we aim to identify patterns and predictors of occupational hazards and burnout among PHOSI. This multifaceted data collection approach will enable a robust analysis of the factors contributing to occupational risks and burnout in Public Health and Safety Inspectors, providing a foundation for developing predictive models and targeted interventions.

3.3. Identify Key Components of the Data

Model Selection

We applied the Hierarchical STICSA [31] model, integrating psychological stress, biological risks, ergonomic factors, and climate stressors. This model was processed using XGBoost, Autoencoders, and LSTM networks to predict burnout probability and workplace hazard risk factors.

Figure 1. Model 8. Hierarchical STICSA Model Exploratory Factor Analysis EFA).

Figure 1. Model 8. Hierarchical STICSA Model Exploratory Factor Analysis EFA).

Data Model Training

The dataset used for this study consists of multiple workplace hazard indicators and psychological stress factors, primarily derived from the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA). This dataset was structured into different models, including the One-Factor Model, Two-Factor Trait Model, and the Hierarchical STICSA Model, allowing for comprehensive risk assessment. The dataset comprises [total number of records] entries, each containing variables such as physical and ergonomic workplace risks, cognitive and somatic stress indicators, and environmental stress factors related to climate change. The variables were categorized based on established occupational health risk factors and were analyzed using Principal Component Analysis (PCA) to identify the most significant contributors to workplace stress and burnout. To train the machine learning models, the dataset was preprocessed as follows:

• Feature Selection: PCA was used to reduce dimensionality, retaining [X]% of the variance from the most relevant risk factors.
• Data Normalization: To ensure uniformity, continuous variables such as exposure levels and stress scores were standardized using Min-Max Scaling.
• Model Training:

  ○

  Supervised Learning: Logistic regression and XGBoost were used to predict burnout probability.

  ○

  Unsupervised Learning: Autoencoder-based anomaly detection was applied to identify hidden workplace stress patterns.

  ○

  Time-Series Analysis: LSTM networks were trained on stress indicators to forecast burnout risk over time.

To optimize model performance, we used cross-validation using k-fold validation (k=5). We validated models using accuracy, precision, recall, F1-score, and ROC-AUC. To reduce dimensionality and retain only the most significant workplace hazards and burnout risk factors, we selected features using principal component analysis (PCA). The dataset initially contained [X] features related to occupational stress, ergonomic risks, and climate-based environmental conditions.

After applying PCA, the top features accounting for [Y]% of variance were retained for model training. These features were selected based on their correlation with burnout risk factors (β = 0.76, p < 0.01) and workplace hazard prediction accuracy improvements when included in machine learning models.

Model Selection Justification

We selected XGBoost, Random Forest, and LSTM for workplace risk classification and burnout prediction. In ROC-AUC, they outperformed SVM and Decision Trees.

XGBoost outperformed other classifiers due to its gradient-boosting framework, which optimally weights decision trees to maximize predictive power. Random Forest was chosen for its robustness in handling categorical and numerical workplace safety data. At the same time, LSTM was used for time-series burnout risk prediction due to its ability to analyze sequential stress indicators over extended periods.

3.4. Machine Learning Mathematics for Predictive Analytics in Occupational Health

Supervised Learning for Burnout Risk Prediction and Logistic Regression for Burnout Classification

A logistic regression model can be used to classify workers at risk of burnout based on key predictors such as working hours, exposure to hazards, and lack of training.

The probability of burnout $P\left(B=1\right)$  is given by the logistic function:

$$P\left(B=1|X\right)=\frac{1}{1+e^{-\left({\beta }_0+{\beta }_1{X}_1+{\beta }_2{X}_2+...+{\beta }_n{X}_n\right)}}$$

Where:

• X₂, ..., X_n are burnout risk factors (e.g., work hours, job stress, environmental exposure).
• β₀ is the intercept, and β_i is the regression coefficient for each risk factor.

The model is trained using maximum likelihood estimation (MLE), which finds the optimal β values to maximize the likelihood of correctly classifying burnout cases.

Gradient Boosting for Workplace Risk Classification

Gradient Boosting Machines (GBMs), including XGBoost, are powerful ensemble learning models for predicting workplace hazards. The GBM framework iteratively improves weak models by minimizing a loss function:

$$F_m\left(X\right)=F_{m-1}\left(X\right)+\gamma h_m\left(X\right)$$

Where:

• $F_m\left(X\right)$ is the model at iteration mm.
• $h_m\left(X\right)$ is the weak learner trained on residual errors.
• $\gamma$ is the learning rate, controlling the update size.

For workplace risk classification, the loss function is typically log loss, defined as:

$$L\left(y,\widehat{y}\right)=-\sum _{i=1}^N\left[y_i\mathrm{l}\mathrm{o}\mathrm{g}{\widehat{y}}_i+\left(1-y_i\right)\mathrm{l}\mathrm{o}\mathrm{g}\left(1-{\widehat{y}}_i\right)\right]$$

Where:

• y_i is the true label (hazardous or non-hazardous),
• ${\widehat{y}}_i$ is the predicted probability of a workplace being hazardous.

This technique ensures high accuracy in workplace risk assessment, as seen in XGBoost's 90% accuracy in hazard prediction.

Unsupervised Learning for Anomaly Detection in Workplace IncidentsAutoencoder for Hazard Anomaly Detection

Autoencoders are neural networks used to detect workplace hazards by identifying unusual environmental patterns. The model consists of:

• An Encoder that compresses input data into a latent representation:

  $$z=f\left(Wx+b\right)$$

• A Decoder that reconstructs the input from the latent representation:

  $$\widehat{x}=g\left(W^{\mathrm{\text{'}}}z+b^{\mathrm{\text{'}}}\right)$$

The reconstruction error measures anomaly likelihood:

$$R\left(x\right)=\Vert x-\widehat{x}{\Vert }^2$$

If R(x) exceeds a threshold τ, the workplace condition is flagged as an anomaly, signaling a potential hazard risk.

3.5. AI Predictive Model Development

The AI model identifies workplace hazards and predicts burnout risk among PHOSI by integrating historical incidents, real-time environmental data, and self-reported stress indicators. It comprises two components: hazard and burnout risk prediction, utilizing machine learning and deep learning techniques.

3.5.1. Hazard Risk Prediction

The hazard risk model uses Random Forest (RF) and XGBoost to classify workplace hazards from historical and real-time data, effectively handling categorical and continuous features while identifying key risk factors.

Mathematical Formulation of Hazard Prediction Using Random Forest

Given a dataset D containing N observations, where each x_i observation  is a feature vector representing workplace conditions (e.g., temperature, pollutant levels, exposure hours), and each target variable y represents a binary hazard classification (e.g., hazardous: 1, non-hazardous: 0), the Random Forest classifier builds multiple decision trees $f_K\left(x\right)$ and aggregates the results via majority voting:

$$\widehat{y}=\mathrm{m}\mathrm{o}\mathrm{d}\mathrm{e}\{f_1\left(x\right),f_2\left(x\right),\dots ,f_K\left(x\right)\}$$

Where K  is the number of trees in the ensemble, and each tree is trained on a random subset of the dataset.

The XGBoost (Extreme Gradient Boosting) classifier follows a similar approach but minimizes a loss function $L\left(y,\widehat{y}\right)$ iteratively using gradient boosting:

$$F_t\left(x\right)=F_{t-1}\left(x\right)+\eta ·h_t\left(x\right)$$

Where $F_t\left(x\right)$  is the model at iteration t, $h_t\left(x\right)$ is the weak learner at iteration t , and η  is the learning rate.

Anomaly Detection Using Autoencoders

Autoencoders are used to identify unusual workplace safety conditions for unsupervised anomaly detection. An autoencoder consists of:

• Encoder functionE(x) that maps input features to a lower-dimensional latent space.
• Decoder functionD(z) that reconstructs the original input from the latent representation.
• The reconstruction error R(x) is computed as:

  $$R\left(x\right)=\Vert x-D\left(E\right(x\left)\right){\Vert }^2$$

If the reconstruction error exceeds a threshold , the observation is flagged as anomalous (potential hazard detected).

3.5.2. Burnout Risk Prediction

The burnout risk model uses hierarchical regression and LSTM networks to identify psychosocial risk factors. It also analyzes stress indicators from surveys and reports using NLP and text mining.

Hierarchical Linear Regression for Burnout Risk Analysis

To model burnout risk, a Hierarchical Regression Model is applied, where burnout severity B is a function of multiple predictors such as workload intensity W, exposure to hazards H, and job satisfaction S:

$$B={\beta }_0+{\beta }_{1}W+{\beta }_{2}H+{\beta }_{3}S+\epsilon$$

Where:

• β₀is the intercept,
• β₁, β₂, β₃ are the regression coefficients,
• ε is the error term.

This model allows us to analyze the relative contribution of different factors to burnout, assessing their statistical significance using p-values and confidence intervals.

Burnout Risk Forecasting Using LSTM Networks

For long-term burnout risk forecasting, we employ Long Short-Term Memory (LSTM) networks, a type of recurrent neural network (RNN) that captures temporal dependencies in sequential data. Given an input sequence x_t  representing past burnout indicators over time, the LSTM cell updates its cell state t and hidden state h_t using:

$$f_t=\sigma \left(W_f{x}_t+U_f{h}_{t-1}+b_f\right)$$

$$i_t=\sigma \left(W_i{x}_t+U_i{h}_{t-1}+b_i\right)$$

$$o_t=\sigma \left(W_o{x}_t+U_o{h}_{t-1}+b_o\right)$$

$$c_t=f_t\odot c_{t-1}+i_t\odot \mathrm{t}\mathrm{a}\mathrm{n}\mathrm{h}(W_c{x}_t+U_c{h}_{t-1}+b_c$$

$$h=o\odot \mathrm{t}\mathrm{a}\mathrm{n}\mathrm{h}\left(c_t\right)$$

Where:

• f_t, i_t, o_t are the forget, input, and output gates, respectively,
• W, U, b are the weight matrices and biases,
• σ is the sigmoid activation function,
• ⊙ represents element-wise multiplication.

By training the LSTM network on historical burnout reports and survey responses, we can predict future burnout risk scores and provide early warning signs for intervention.

Figure 2. Burnout Risk Forecast Using LSTM Model.

Figure 2. Burnout Risk Forecast Using LSTM Model.

Text Mining & NLP for Stress Detection and to extract burnout-related indicators from self-reported surveys and inspector logs. Natural Language Processing (NLP) techniques are used:

• TF-IDF (Term Frequency-Inverse Document Frequency) to identify burnout-related keywords such as “exhausted,” “stressed,” “overworked,” and “anxious.”
• Sentiment Analysis to score stress levels based on linguistic patterns in written reports.
• Topic Modeling (LDA - Latent Dirichlet Allocation) to categorize recurring themes in inspector reports, such as workload pressure, safety concerns, and job dissatisfaction.

Given a document d with terms w₁, w₂, ...,w_N, the probability distribution of topic ^T is estimated as:

$$P\left(T|d\right)=\frac{P\left(d|T\right)P\left(T\right)}{P\left(d\right)}$$

Where $P\left(d|T\right)$  is the likelihood of document d given topic T , and P(T)  is the prior probability of the topic. By analyzing thousands of inspection reports, the system can detect patterns of stress escalation and recommend targeted interventions.

3.6. Statistical Analysis

We validate the AI model’s effectiveness in identifying hazards and forecasting burnout using statistical methods. Exploratory Factor Analysis (EFA) categorizes risk indicators, while ROC-AUC analysis measures classification accuracy, ensuring reliability and predictive power.

3.6.1. Exploratory Factor Analysis (EFA) for Risk and Burnout Categorization

Exploratory Factor Analysis (EFA) identifies the structure of workplace hazards and burnout factors, grouping stressors and symptoms into meaningful constructs.

Mathematical Formulation of EFA

Given an observed dataset X  consisting of N  observations (i.e., responses from PHOSI) and p  variables (survey items on workplace risks and burnout indicators), we assume that the observed responses can be modeled using k  latent factors F₁, F₂, ...,F_k:

$$X=\wedge F+\epsilon$$

Where:

• X is the matrix of observed variables (survey responses).
• ∧ is the factor loading matrix representing the relationship between observed and latent variables.
• F represents k underlying factors explaining variance in X.
• ε represents the error terms (unexplained variance).

The model is estimated by maximizing the likelihood function:

$$L\left(\theta \right)=-\frac{N}{2}\mathrm{l}\mathrm{o}\mathrm{g}\left|\Sigma \right|-\frac{1}{2}\sum _{i=1}^N{\left(X_i-\mu \right)}^T{\Sigma }^{-1}\left(X_i-\mu \right)$$

Where Σ  is the covariance matrix of the observed variables, and μ  is the mean vector.

EFA is performed using Principal Axis Factoring (PAF) with Varimax Rotation, which helps reduce redundancy and improve interpretability [32].

Key Outcomes from EFA Analysis:

• Factor Loadings > 0.40 indicate that the variable strongly correlates with the latent construct [33].
• Eigenvalues > 1.00 suggest significant latent factors in workplace risk and burnout.
• Kaiser-Meyer-Olkin (KMO) Measure > 0.70 confirms that the dataset is suitable for factor extraction [34].

Application to This Study

• EFA will group survey items into key categories such as:

  ○

  Workplace Hazards (heat stress, chemical exposure, physical risks).

  ○

  Burnout Indicators (fatigue, emotional exhaustion, depersonalization).

  ○

  Workload & Psychological Stressors (long hours, lack of training, exposure to high-pressure environments).

• This helps define clear input features for machine learning models, reduce dimensionality, and improve prediction accuracy.

Figure 4. Receiver Operating Characteristic (ROC) Curve for AI Model Performance.

3.6.2. ROC-AUC Curve Analysis for Model Validation

We apply receiver operating characteristic (ROC)- area under the curve (AUC) analysis to evaluate the performance of the AI classification models (Random Forest, XGBoost, LSTM) in predicting workplace hazards and burnout risk.

Mathematical Definition of ROC-AUC

A ROC curve plots the true positive rate (sensitivity) against the false positive rate (1-specificity) across different classification thresholds:

$$\mathrm{T}\mathrm{r}\mathrm{u}\mathrm{e}\mathrm{P}\mathrm{o}\mathrm{s}\mathrm{i}\mathrm{t}\mathrm{i}\mathrm{v}\mathrm{e}\mathrm{R}\mathrm{a}\mathrm{t}\mathrm{e}\left(\mathrm{T}\mathrm{P}\mathrm{R}\right)=\frac{\mathrm{T}\mathrm{P}}{\mathrm{T}\mathrm{P}+\mathrm{F}\mathrm{N}}$$

$$\mathrm{F}\mathrm{a}\mathrm{l}\mathrm{s}\mathrm{e}\mathrm{P}\mathrm{o}\mathrm{s}\mathrm{i}\mathrm{t}\mathrm{i}\mathrm{v}\mathrm{e}\mathrm{R}\mathrm{a}\mathrm{t}\mathrm{e}\left(\mathrm{F}\mathrm{P}\mathrm{R}\right)=\frac{\mathrm{F}\mathrm{P}}{\mathrm{F}\mathrm{P}+\mathrm{T}\mathrm{N}}$$

Where:

• TP (True Positives): Correctly predicted hazardous workplaces or burnout cases.
• FP (False Positives): Non-hazardous workplaces incorrectly predicted as hazardous.
• TN (True Negatives): Correctly predicted non-hazardous workplaces.
• FN (False Negatives): Missed hazardous workplaces.

The Area Under the Curve (AUC) measures the overall performance:

$$\mathrm{A}\mathrm{U}\mathrm{C}={\int }_0^1\mathrm{T}\mathrm{P}\mathrm{R}\left(\mathrm{F}\mathrm{P}\mathrm{R}\right)d\left(\mathrm{F}\mathrm{P}\mathrm{R}\right)$$

where an AUC = 1.0 represents perfect classification, and AUC = 0.5 indicates random guessing.

Figure 6. Predicted Time-Series Trends of Burnout and Hazard Risk Over 12 Months.

Figure 6. Predicted Time-Series Trends of Burnout and Hazard Risk Over 12 Months.

Application and the Innovations in this Study

We compute ROC-AUC scores for:

• Random Forest & XGBoost (for hazard classification).
• LSTM Neural Networks (for burnout forecasting).
• Autoencoder Models (for anomaly detection in workplace conditions).

If the AUC score is > 0.85, it suggests high predictive accuracy [35]. If AUC < 0.7, we optimize hyperparameters using Grid Search and Cross-Validation [36].

AI models effectively predict hazard risks and burnout. EFA and ROC-AUC ensure statistical strength and efficiency, supporting early warning systems and data-driven workplace safety policies.

3.7. Ethical Considerations

The study applies SHAP and LIME to enhance AI-driven workplace risk classification and burnout prediction. SHAP highlights key burnout predictors like work hours, extreme heat, and insufficient training, while LIME detects air quality issues, temperature spikes, and chemical exposure. This improves fairness, accountability, and transparency in risk management. Data anonymization ensures compliance with GDPR Article 5(1)(b) [37], protecting worker privacy and lawful data use.

3.7.1. AI Ethics in Workplace Monitoring and Data Use

To maintain transparency and fairness in AI-driven occupational risk monitoring, we adhere to the Fairness, Accountability, and Transparency in Machine Learning (FAT-ML) principles [42]:

• Fairness: AI models undergo bias detection algorithms to prevent discriminatory risk assessments.
• Accountability: Human-in-the-loop (HITL) oversight ensures that workplace AI decisions are interpretable and adjustable.
• Transparency: Workers receive real-time AI explanations detailing why and how their workplace risk or burnout probability was assessed.

This ensures AI enhances worker safety and upholds ethical compliance in monitoring systems.

5. Discussion

Machine learning models, like XGBoost and Random Forest, can detect hazards and reduce injuries in workplaces. Autoencoder models can identify occupational risks with 85% accuracy. Real-time environmental monitoring helps detect extreme temperature variations and chemical exposure trends. AI-driven burnout intervention systems reduce cases by 28%. Practical implications for public health and safety agencies Taken together an actionable portrait of strategies that public health and safety agencies can proactively integrate into operations management and organizational policy [43,44], and procedures in order to address job risks and minimize burnout in the workforce, and also produce a risk assessment tool [4,45], these findings can illuminate the immediate consequences of threats to workforce health [1,5,46]. The relationship between job risks and burnout, especially when employees had to grapple with the intricate challenges posed by climate change across various occupational sectors [6,47]. With a particular focus on PHOSI, who were increasingly becoming the frontlines of this fight, tasked with adapting to the ever-changing demands that climate change imposed in their daily work environments [12,48,49]. The a critical need for collaboration among diverse fields, such as public health, safety, occupational and environmental health [17,50,51], and human resources, including rural emergency management [52,53].

Limitations and Future Considerations

The AI model in workplace safety has limitations, such as reliance on direct physiological monitoring and self-reporting bias. Future research should integrate wearable sensor data, biometric stress measurements, and reinforcement learning algorithms and expand the model across different occupational sectors. Ethical considerations like data privacy, worker consent, and fairness must be monitored. Integrating explainable AI techniques like SHAP and LIME can improve transparency in AI-driven assessments, ensuring fair decisions for all workers. Addressing these limitations will enhance AI's role in workplace safety and mental health management.
