Setting up a confined space entry system correctly is essential for safe and efficient operations. The SENTRY Tripod Kit is designed to provide a stable anchorage point for confined space access and rescue applications, but proper setup, inspection, and handling are critical before use.
This guide explains how to set up a confined space access system step by step, based on best practice procedures.
What is a confined space access system?
A confined space access system is a combination of anchorage equipment, lifting or retrieval devices, and fall protection components used to safely lower, retrieve, or protect a worker entering a restricted area such as a tank, shaft, trench, or manhole.
The SENTRY Tripod system is commonly used alongside:
- Fall arresters (SRLs)
- Rescue winches
- Confined space harnesses
- Certified anchorage brackets and accessories
Safety checks before setup
Before assembling any confined space system, ensure:
All users:
- Have read the User Instructions
- Are trained and competent
- Are familiar with the emergency contingency plan
- Are supplied with and wearing correct PPE
Preparing the work area
Refer to the completed risk assessment of the work area to ensure all necessary equipment is present.
Ensure all safe working loads and rope lengths are adequate for the application.
Perform pre-use inspections on each piece of equipment.
Prepare the access area by removing anything that may cause an obstruction and make sure the floor is cleared of any debris that may cause the feet of the tripod to slide, such as loose gravel or leaves. On colder days, it is recommended to place grit/salt down to defrost any ice where the feet are to be placed.
If the access point has a cover that is safe to walk on, the tripod can be set up directly over it. Otherwise, setup must be completed away from the hole, and the tripod system moved over once ready to be used.
Step-by-step: SENTRY Tripod Kit setup
1. Unfold and secure the SENTRY tripod
- Unfold the tripod legs
- Insert the locking pin
- Adjust legs if needed to allow the pin to fully engage
2. Fit the SAVER fall arrest bracket
- Attach the bracket to a tripod leg
- Adjust height depending on leg extension
- Ensure it aligns with the top pulley
- Tighten clamps securely
3. Install the SAVER SRL 3-way
- Align mounting holes and insert securing pin
- Rotate unit into position
- Secure using the wing screw
- Confirm correct alignment with pulley system
4. Route the lifeline correctly
- Feed the cable over the pulley
- Ensure it runs down the centre of the tripod
- Check it sits correctly under the locking pin and pulley wheel
5. Install the Globestock WINCH
- Lift winch into position with clamps open
- Align with top pulley
- Tighten clamps securely after positioning
Important:
- The winch rope must always pass underneath the top bar
- Never route it over the top
6. Configure the winch handle
- Remove the winding handle before free-run operation
- Use the free-run lever to extend cable
The handle is standard on the right-hand side, but the unit can be rotated by 180° if site conditions require left-side operation.
7. Extend tripod legs into final position
- Two people required for safe handling
- Extend one leg at a time while the tripod is tilted
- Secure each leg using locking clips before moving to the next
8. Position and connect equipment
- Move SENTRY tripod into final position over the access point
- Attach connectors to separate harness attachment points
- Confirm system stability before use
Key safety reminders
- Always ensure the locking pin is installed during use
- Never exceed safe working load limits
- Keep lifeline properly routed at all times
- Follow manufacturer instructions for all components
- Only trained personnel should install or operate the system
Why correct setup matters
A properly configured confined space access system ensures:
- Safe entry and retrieval
- Stable anchorage under load
- Reduced risk during emergency recovery
- Compliance with site safety procedures
The SENTRY Tripod Kit is designed to simplify confined space operations, but performance always depends on correct setup and user competence.
Final thoughts
Confined space work demands precision, preparation, and reliable equipment. When set up correctly, the SENTRY Tripod system provides a dependable solution for entry and rescue applications across industries including utilities, construction, water treatment, and industrial maintenance.
