Study Notes
Preventive Safety Measures
- There are 4 types of preventive safety measures
Types of Preventive Safety Measures
- Human action (e.g. operator error prevention, training, and procedures)
- Physical preventive safety measures (e.g. relief devices, safety instrumentation)
- Inherent safety measures (e.g. inherently safer design)
- Procedural safety measures (e.g. maintenance, inspection, and testing)
Application of Preventive Safety Measures
- A safety shut down system can prevent the undesirable emission of flammable gases from a landfill when the outlet of the knock-out pot of the flare system is blocked
Preventing Over-Pressurization
- Physical preventive safety measures, such as relief devices, are required to prevent over-pressurization in vessels
- Guidelines for specifying relief locations include:
- Identification of potential over-pressurization sources
- Determination of relief requirements
- Selection of relief devices
- Installation and maintenance of relief devices
Mitigative Safety Measures
- These are measures taken after an incident to mitigate its effects
- Examples of mitigative safety measures include:
- Emergency response planning
- Firefighting
- Evacuation procedures
Emergency Response Plan (ERP)
- Objectives of an ERP include:
- Minimizing harm to people and the environment
- Reducing the impact of an incident
- Facilitating effective emergency response
- Key components of an ERP include:
- Emergency response procedures
- Communication plans
- Training and drills
Pressure Relief Valve
- A pressure relief valve is a type of relief device that automatically opens to release excess pressure and then closes when the pressure returns to a safe level
Preventive Safety Measure
- A preventive safety measure is a measure taken to prevent a loss event or to interrupt the chain of events leading to a loss event
Relief Event Scenarios
- Examples of relief event scenarios include:
- Over-pressurization of a vessel
- Rupture of a pipeline
- Failure of a critical safety device
