Spring and Cable Tension Safety: the full procedure
The business rule that all spring and cable tension work is performed only per the manufacturer's instructions by a trained technician - never improvised.
- Applies to: All technicians and crew
- Frequency: Any job touching springs or cables
- Scope: This is a deferral and safety-control procedure, not a how-to. It defines who may touch tensioned components and mandates that all spring winding, cable replacement, and tension adjustment defer to the manufacturer's installation instructions, a trained garage door technician, OSHA, and the business safety plan.
What you need
- Manufacturer install manual
- Business safety plan
- Lockout/tagout supplies
- PPE (eye protection, gloves)
- Incident log
The procedure, step by step
- Stop and assess before any tension work — Before touching a spring, cable, or shaft, confirm whether the component is under tension. If it is, this is a deferral point - proceed only per the rules below.
- Confirm technician qualification — Only a technician trained per the manufacturer's instructions and your safety plan may perform spring winding or cable work. Untrained crew never touch tensioned components.
- Use only manufacturer-specified tools and method — Spring and cable work follows the manufacturer's installation instructions and approved tools exactly. Improvised tools (screwdrivers, rebar) are prohibited - DASMA warns these cause catastrophic injury.
- Wear required PPE — Eye protection and gloves are required for any work near tensioned components per OSHA and the safety plan. Keep your face and body out of the line of force.
- Keep the work area clear — No customers, helpers, or bystanders within the danger zone of a tensioned spring or cable during the work.
- Verify safety cables on extension springs — Per DASMA, extension springs must have containment safety cables. If missing, defer the correction to a trained technician per the manufacturer's instructions.
- Escalate anything outside training — If the situation falls outside the manufacturer's instructions or the tech's training, stop and escalate to a qualified technician or the owner. Never guess on tension.
- Log the work and any near-miss — Record who performed the tension work and log any incident or near-miss per the safety plan for review.

Frequently asked questions
Why does this SOP refuse to give spring-winding steps?
Because providing winding specifics would invite untrained staff to attempt one of the most dangerous tasks in the trade. Torsion springs store hundreds of pounds of force, and DASMA documents that a slipped winding bar can break bones or worse. The SOP deliberately defers all winding and tension work to the manufacturer’s instructions, a trained technician, OSHA, and your safety plan.
Can a helper or new hire assist with spring work?
Untrained crew must never touch tensioned springs or cables. Only a technician trained per the manufacturer’s instructions and your safety plan may perform the work, and bystanders must be cleared from the danger zone. Per DASMA, extension springs also require containment safety cables, and any missing cable is corrected by a trained technician, not improvised.
