OHSE stands for Occupational Health, Safety, and Environment. It encompasses the principles, practices, and legal frameworks designed to ensure a safe and healthy workplace while minimizing environmental impacts. OHSE is crucial for businesses across industries to protect employees, reduce workplace hazards, and comply with regulations related to health, safety, and the environment.
OHSE: A Simple Breakdown

- Occupational Health: Focuses on the physical and mental well-being of workers in the workplace.
- Safety: Aims to prevent accidents, injuries, and incidents by identifying potential hazards and implementing preventive measures.
- Environment: Deals with minimizing the environmental impact of workplace activities, including waste management, pollution prevention, and sustainable practices.
OHSE Formula: The Equation of Safety and Health
In OHSE, the equation that represents the relationship between hazards, risk, and safety controls can be expressed as:
OHSE Equation:R=H×E×CR = H \times E \times CR=H×E×C
Where:
- R = Risk (overall risk level)
- H = Hazard (potential source of harm)
- E = Exposure (level of exposure to the hazard)
- C = Control (effectiveness of safety measures in place)
The goal in OHSE is to reduce the value of risk (R) by minimizing exposure (E) and implementing effective controls (C), which reduces the impact of hazards (H).

Here is a chart that visually represents the OHSE risk reduction process. It illustrates the relationship between hazards, exposure levels, controls, and their impact on overall risk. The goal is to reduce risk by minimizing exposure and applying effective safety controls at different hazard levels.
As shown, when controls are more effective, the resulting risk decreases, even if the hazard or exposure is high. This concept is key in managing workplace health, safety, and environmental factors.
