Environmental Health and Safety Nurses play a vital role in integrating environmental knowledge into their nursing practice to promote community health. When using an upstream approach, community health nurses focus on addressing social determinants of health proactively to prevent illness rather than merely treating disease after onset. Strategic actions include community assessment, policy advocacy, health education, and collaboration with stakeholders (Brown & Johnson, 2020). The precautionary principle guides this approach by emphasizing prevention even when scientific evidence is not definitive, prioritizing safety and health protection (Raffensperger & tickner, 2013). The core functions of public health—assessment, policy development, and assurance—are essential in translating these strategies into effective community interventions (WHO, 2018). Applying these principles enables nurses to advocate for healthier environments and equitable health outcomes.

Environmental health and safety are critical components of public health nursing, particularly when considering the upstream approach aimed at prevention and health promotion. Community health nurses are uniquely positioned to implement strategic actions that address social, economic, and environmental factors influencing health outcomes. These actions include conducting comprehensive community assessments to identify risk factors, advocating for policies that promote environmental safety, and providing health education to empower populations (Brown & Johnson, 2020). An essential concept in this context is the precautionary principle, which suggests that action should be taken to prevent harm even when scientific certainty is lacking. This principle prioritizes precautionary measures in environmental health initiatives to protect vulnerable populations (Raffensperger & tickner, 2013).
Applying the precautionary principle in public health entails adopting proactive policies and interventions that mitigate potential risks before they materialize, thereby safeguarding communities against environmental hazards. This approach aligns with the core functions of public health—assessment, policy development, and assurance—forming a framework that promotes health equity and environmental justice (WHO, 2018). For example, in policy development, nurses might advocate for stricter pollution controls or safer housing standards to reduce exposure to toxins. Through assessment, they can monitor environmental risks and identify vulnerable groups. Assurance involves ensuring that services and policies are effectively implemented and maintained.
The core functions serve as foundational strategies for implementing upstream interventions. They enable community health nurses to proactively address root causes of health disparities linked to environmental factors. For instance, assessment helps identify communities exposed to industrial pollutants, guiding policy development for cleaner environments. Assurance ensures that community programs and regulations are enforced effectively. Overall, integrating these core functions with the precautionary principle fosters a comprehensive approach in public health nursing to prevent environmental health hazards and promote sustainable communities. This approach not only improves individual health outcomes but also advances health equity at the population level (Jacobs & Herce, 2019). Thus, community health nurses are instrumental in applying upstream strategies aligned with core public health functions and the precautionary principle to create healthier environments.
