Understanding Hazard and Risk – Key Concepts for Safety and Success

Hazard:
- A hazard is anything that has the potential to cause harm, injury, damage, or adverse effects. It is a source or situation with the potential to cause harm under certain conditions.
- A hazard does not necessarily cause harm by itself but could do so if the situation or conditions are right.
Examples of hazards:
- Chemicals (like asbestos or toxic substances)
- Machinery (like a rotating blade)
- Weather conditions (like a hurricane)
- Natural events (like earthquakes)
- Radiation or noise
Risk:
- Risk is an uncertain event that may or may not happen.
- It refers to the probability (likelihood) and impact (severity) of the harm.
Risk formula:
Risk=Probability of harm × Impact of harm
Negative Risks (Threats): Risks that can have a detrimental impact on the project, such as delays, cost overruns, or resource shortages.
Positive Risks (Opportunities): Risks that could have a beneficial impact on the project, such as a new technology that speeds up production or a supplier offering better pricing.
Tool used: A Risk Register is a tool commonly used in project management to identify, assess, and track potential risks that could affect the success of a project.
Examples of risk:
- The risk of injury when working with machinery depends on how often the machine is used, how well it’s maintained, and how properly it’s operated.
- Late delivery of construction materials.
In summary, hazard is the danger itself, and risk is the chance that the hazard will cause harm in a given situation.
Scenarios:
Construction Project: Building a New School
Project Type: Construction of an elementary school.
Resource Management: The construction manager needs to plan and allocate resources effectively. This includes hiring labor, securing materials, and managing the equipment needed.
- Example: A resource leveling technique is used to ensure that the most skilled workers are available for critical tasks such as laying the foundation and constructing the building’s frame.
Budget Management: The team must stick to the project budget, considering the costs for materials, permits, labor, and utilities.
- Example: During the project, the price of steel increases unexpectedly. The manager renegotiates contracts with suppliers to ensure the costs stay within the allocated budget.
Quality Management: Regular inspections and tests are performed to ensure the construction meets safety standards and building codes.
- Example: During the construction phase, the manager arranges for independent safety audits and makes adjustments to the structure if required.
Healthcare Project: Implementing a New Electronic Health Record (EHR) System
Project Type: Deployment of a new EHR system in a hospital.
Scope and Requirements Management: The hospital’s IT department works with doctors, nurses, and administrative staff to determine what functionalities are required from the new EHR system.
- Example: Key features such as patient history tracking, appointment scheduling, and patient-doctor communication are identified, while more advanced features (like AI-assisted diagnostics) are saved for future updates.
Communication Management: Ensuring all team members, from healthcare providers to IT professionals, are updated on the progress of the system installation.
- Example: The project manager sends out weekly progress reports to hospital staff, explaining updates on system testing, training sessions, and troubleshooting issues.
Training and Support: After the system is implemented, training sessions are conducted for hospital staff on how to use the new EHR system.
- Example: A support team is set up to answer questions and address problems that arise during the initial phase of use.
