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.
