Key Aspects of Line Break Safety

1. Pressure Management: Ensuring systems are designed and operated within safe pressure limits.
2. Material Selection: Choosing appropriate materials for lines based on application, pressure, and media (fluid, gas).
3. Regular Inspection: Routine checks for signs of wear, corrosion, damage.
4. Protection Measures: Protecting lines from external damage (physical protection, routing).
5. Emergency Response Plans: Having plans for dealing with line breaks, leaks.
6. Training: Personnel trained in handling and safety procedures.

Hazards Associated with Line Breaks

1. Fluid/Gas Release: Potential for hazardous substance release.
2. Pressure Release: Forceful release can cause injury or damage.
3. Fire/Explosion Risk: Depending on media (flammable gases/liquids).
4. Environmental Impact: Spills or releases affecting environment.

Industries Where Line Break Safety is Critical

1. Oil and Gas: Pipelines for crude oil, natural gas.
2. Chemical Processing: Handling hazardous chemicals.
3. Hydraulic Systems: High-pressure hydraulic lines in machinery.
4. Power Generation: Steam lines, cooling systems.

Safety Measures

1. Pressure Relief Devices: Safety valves, rupture discs.
2. Leak Detection Systems: For early detection of leaks.
3. Piping Codes and Standards: Following codes for pressure piping.
4. Personal Protective Equipment (PPE): Appropriate PPE for workers.

Checkpoints for Line Breaking

1. Dismantling piping for repairs or replacement must be done with caution. Check to make sure the line has been de-pressurized, drained and cleared from possible harmful n substances and that a valid permit has been issued.
2. When opening a line at a flange, start by slightly loosening, or “breaking” all bolts in an even manner.
3. Bolts should be completely loosened at opposite sides of the piping to evenly distribute pressure on the flange. In other words, do not loosen bolts randomly as this can result in unnecessary strain on the flange, keeping four loosened but not released bolts in cross position up to breaking flanges! WHY?
4. When using a cold cutting device, such as a “pipe cutter” or “water cooled hacksaw”, always make sure an updated Procedure, Method statement, relevant JHA and work permit has been issued.
5. When cutting a pipe, use a pipe cutter slowly and to provide proper means to prevent the piping from “snapping” apart.
6. Allow any residual product or chemicals in the pipe to drain out and remove all flammables from the area before performing any hot work.
7. All piping must be stoppled, or equally plugged, gas tested and have a hot work permit issued before grinding, welding, torch cutting, or using other sources of ignition.

Examples of Line Break Incidents

1. 1. Pipeline Ruptures: Can lead to environmental damage and safety risks.
2. 2. Hydraulic Line Failures: Can cause equipment damage and injury.
