Stored Energy Release Hazards

Key Hazards

• Struck-by injuries from snapping straps or tensioned equipment
• Eye and face injuries from released stored energy
• Unexpected movement of compressed, stretched, or pressurized components

2–3 Minute Talk Script

Stored energy release hazards exist in nearly every workplace and can cause serious injuries when tension, pressure, compression, or mechanical force is suddenly released. Workers may not recognize how much force is stored in stretched straps, compressed springs, hydraulic systems, suspended loads, or secured materials until failure occurs.

Different operations create different stored energy hazards. Utility crews may work with tensioned chains or pressurized piping, mechanics encounter compressed springs and hydraulic systems, warehouse workers use ratchet straps and load securement devices, and construction crews often work around suspended or tensioned materials.

Bungee cords, ratchet straps, tow straps, chain binders, compressed air systems, and spring-loaded equipment can all recoil violently if they fail or release unexpectedly. These incidents commonly cause injuries to the eyes, face, hands, and upper body.

Workers should inspect straps, hooks, chains, fittings, and pressurized components before use. Damaged or worn equipment should be removed from service immediately. Workers should also position themselves outside the direct line of tension whenever possible.

Stored energy hazards increase when workers rush tasks, improvise equipment, or exceed load ratings. Proper tools, controlled release procedures, and communication between workers help prevent sudden equipment movement or catastrophic failure.

Situational awareness is critical around stored energy systems. Workers should identify where energy is being stored before beginning work and understand how sudden release could affect nearby personnel or equipment.

Safety Reminders

• Inspect straps, chains, and tensioned equipment before use.
• Stay clear of the direct line of tension whenever possible.
• Remove damaged securement devices from service immediately.
• Use equipment within rated load limits only.
• Recognize stored energy hazards before beginning work.

Ask the Crew

• What stored energy hazards exist during today’s tasks?
• Are any straps, chains, or tensioned systems damaged or overloaded?
• Do workers understand safe positioning around tensioned equipment?
• What procedures are in place to safely release stored energy?
