2.5. The 7 steps that save lives
ABB’s 7 steps that save lives concept is a series of actions that must take place
prior to commencing work on or near electrical installations.
1) Prepare for the work: do an on-site risk assessment or job hazard
analysis that considers the limits of approach for shock and arc-flash.
• Be in possession of a clear work order to execute the work.
• When required, the access or work permit is to be obtained by a
person who is authorized for the specific electrical system.
• Engage the person responsible for electrical equipment or system
to review single-line diagrams, schematics, switching plans, etc.
• Ensure the competence of workers.
• Check for proper tools for the job.
• Determine and select the proper arc-rated Personal Protective
Equipment (PPE).
• Decide of the appropriate work methods and initiate the Permit
To Work (PTW) process.
2) Clearly identify the work location and equipment.
• Use your senses (sight, hearing and smell) to identify
problem areas.
• Define the work area via barriers and barricading and
label equipment.
• Avoid distractions such as talking or texting on the phone.
3a) Disconnect all sources of supply.
• If ABB is responsible for switching and it cannot be done
remotely, then the person performing the switching must be
properly trained and wearing the proper PPE identified in step 1.
• The Person in Charge of Work (PICW) must ensure that switching
is performed in the proper manner by witnessing it from a safe
distance if present on site or by engaging the person responsible
for switching to identify all isolation points.
3b) Secure against reconnection by applying Lockout/Tagout.
• Apply Lockout/Tagout (LOTO) to the energy isolation device and
if multiple energy isolation devices are involved, then Group LOTO
must be implemented with the PICW serving as the
Group LOTO Leader.
