What is Line Stopping?
Before diving into safety protocols, let’s quickly explain what line stopping involves:
Line stopping is a method where we insert a temporary plug (or “stopper”) into a live, pressurised pipeline. This creates a seal that blocks flow at a specific point, allowing work to happen downstream while the rest of the system keeps running.
The process typically involves:
- Attaching a fitting to the pipe
- Creating an access hole using special drilling equipment
- Inserting the line stopping tool to block the flow
- Completing the needed repairs or connections
- Removing the line stop and sealing the access point
Each of these steps needs careful safety management.
Risk Assessment: Always the First Step
Every line stopping operation begins with a thorough risk assessment. This isn’t just paperwork – it’s a crucial safety step that includes:
- Identifying all potential hazards
- Assessing pipeline contents and pressure
- Checking pipe condition and material
- Evaluating the work environment
- Identifying nearby equipment or structures
- Planning emergency response procedures
We never proceed without a complete risk assessment that’s been reviewed by our safety team.
Essential Safety Equipment for Line Stopping
The right equipment is vital for safe line stopping. Our teams always use:
Personal Protective Equipment (PPE)
- Hard hats with face shields where needed
- Safety glasses and ear protection
- Chemical-resistant gloves suitable for the pipe contents
- Fire-resistant coveralls
- Steel-toed safety boots
- Respiratory protection if hazardous materials are present
Site Safety Equipment
- Gas monitors and leak detectors
- Fire extinguishers appropriate for the materials involved
- Emergency eyewash stations
- First aid kits
- Communication devices
- Proper lighting
- Barricades and safety signs
Staff Training and Certification
Equipment alone isn’t enough. Everyone involved in line stopping operations must have:
- Formal training in line stopping procedures
- Up-to-date certifications
- Regular safety refresher courses
- Knowledge of emergency protocols
- Experience with the specific equipment being used
We maintain detailed training records and never assign staff to tasks they aren’t qualified for.
Pre-Job Safety Briefing
Before any work begins, we hold a safety briefing with everyone involved. This meeting covers:
- The specific job steps and potential risks
- All safety protocols relevant to this job
- Roles and responsibilities of each team member
- Communication procedures
- Emergency response plans
- Questions and concerns from any team member
These briefings ensure everyone starts with a clear understanding of safety requirements.
Pipeline Pressure Management
Managing pressure safely is at the heart of line stopping. Our protocols include:
- Verifying actual line pressure before beginning work
- Using equipment rated for higher pressure than what’s in the pipe
- Installing pressure gauges to monitor conditions during the job
- Having procedures ready for unexpected pressure changes
- Working within safe pressure limits for all components
We never exceed the safe working pressure of our equipment or the pipeline itself.
Controlling the Work Area
A controlled work environment helps prevent accidents. We always:
- Set up a clearly marked work zone with limited access
- Remove trip hazards and obstacles
- Position equipment safely to prevent falls or equipment damage
- Ensure adequate lighting in all work areas
- Keep unnecessary personnel away from active operations
- Maintain clear emergency exit paths
Safe Drilling Procedures
Creating the access hole for a line stop requires specific safety measures:
- Using the correct drilling equipment for the pipe material
- Securing the drilling machine properly to prevent movement
- Following proper drilling speeds based on pipe material
- Containing any chips or debris that could cause injury
- Having backup equipment ready in case of problems
- Using proper cutting lubricants for the material being drilled
Handling Pipeline Contents Safely
Different pipeline contents require different safety approaches:
Water Lines
- Controlling water spray during tapping
- Managing slippery conditions
- Having drainage systems in place
Gas Lines
- Using explosion-proof equipment
- Implementing continuous gas monitoring
- Eliminating ignition sources
- Having ventilation systems in place
- Following strict grounding procedures
Chemical Lines
- Using chemical-specific protective equipment
- Having neutralisation materials ready
- Following specific handling procedures for the chemical involved
- Having decontamination stations ready
Equipment Inspection and Testing
All line stopping equipment must be regularly inspected:
- Visual checks before each use
- Pressure testing of components
- Checking seals and gaskets for wear
- Testing stopping heads for proper operation
- Verifying all safety features are working
- Maintaining detailed inspection records
We immediately remove any damaged or worn equipment from service.
Emergency Response Protocols
Despite all precautions, emergencies can happen. Our teams are prepared with:
- Clear emergency shutdown procedures
- First aid training for all team members
- Spill containment equipment
- Emergency contact information for local authorities
- Evacuation plans
- Regular emergency drills
Communication During Line Stopping
Good communication prevents accidents. Our protocols include:
- Using clear hand signals when needed
- Maintaining radio contact between team members
- Regular status updates during critical operations
- Clear reporting procedures for any safety concerns
- Open communication between all team members
Post-Job Safety Review
After completing a line stopping job, we hold a safety review to:
- Discuss what went well and what could be improved
- Record any safety incidents or near misses
- Update procedures based on what we learned
- Document any equipment issues
- Recognise good safety practices
This continuous improvement helps make future jobs even safer.
Why These Protocols Matter
Following these safety protocols isn’t just about compliance—it’s about making sure everyone goes home safely. Proper line stopping safety also:
- Protects the environment from spills or leaks
- Prevents damage to valuable infrastructure
- Maintains service to customers who rely on the pipeline
- Builds trust with clients who know we prioritise safety
- Helps jobs finish on time without safety-related delays
