Working in Tight or Confined Spaces

Mechanical work offshore often requires using tools in tight or awkward positions — behind pumps, under pipes, inside modules, or in limited-access areas on platforms.

These environments greatly increase the risk of slips, pinch points, impact injuries, and loss of control.

This lesson teaches safe methods for working in restricted spaces while maintaining proper tool handling and situational awareness.

1. Risk Factors in Tight Spaces

• Limited visibility

You may not clearly see the tool or bolt.

• Restricted movement

Reduced ability to reposition or avoid hazards.

• Increased pinch points

Hands are easily trapped between equipment.

• Awkward body positioning

Creates poor leverage and instability.

• Difficulty in maintaining line-of-fire control

Unexpected tool movement becomes more dangerous.

2. Safe Approaches for Confined Tool Use

A. Plan the Task Before Starting

• Identify hazards
• Understand tool access points
• Confirm what must be loosened, removed, or isolated
• Decide if a different tool or approach is safer

B. Improve Visibility

• Use headlamps or work lights
• Check for reflective hazards
• Ensure shadows don’t hide pinch points

C. Use the Right Tools for the Space

• Offset or angled wrenches
• Stubby screwdrivers
• Low-profile ratchets
• Flexible extensions

Never force tools that don’t fit.

D. Maintain Controlled Movements

• Move tools slowly
• Apply force gradually
• Keep your other hand clear of pinch points

E. Communicate

If working with others:

• Inform them of hand positions
• Coordinate movements
• Ensure no one unexpectedly moves equipment

3. Avoiding Pinch Points in Tight Areas

• Know where your hands are at all times
• Avoid placing fingers between fixed and moving parts
• Use pry bars or alignment tools instead of fingers
• Never reach blindly behind components

4. Working With Restricted Leverage

When you cannot apply full force:

• Use torque multipliers if available
• Change your angle rather than forcing the tool
• Use tools designed for confined spaces
• Get assistance if force required exceeds safe range

5. When to Stop Work

Stop immediately if:

• You cannot see what your hands are doing
• Tool slip risk is too high
• Leverage is unsafe
• Another crew member enters your line-of-fire
• The space becomes unsafe due to movement or vibration

Key Takeaways

• Tight spaces require enhanced awareness
• Use correct tools and controlled movements
• Maintain visibility and clear line-of-fire
• Avoid pinch points and unstable positions
• Stop if conditions become unsafe
