Minimise the risk of arc flash incidents through the application of Lockout Tagout (LOTO) procedures.

Preventing arc flash incidents in the workplace is crucial for the safety of personnel and the protection of equipment. Two important safety practices to mitigate the risk of arc flash incidents are Lockout Tagout (LOTO) procedures and proper electrical safety measures. Let’s delve into each of these practices:

Lockout Tagout (LOTO) Procedures:

Lockout Tagout is a safety procedure used to ensure that dangerous machinery and energy sources are properly shut off and not restarted while maintenance or servicing is being performed. While LOTO is often associated with mechanical equipment, it’s also essential for electrical work to prevent arc flash incidents. Here’s how LOTO can help prevent arc flash:

Lockout: Physically isolate the electrical equipment from its energy source by using locks or other devices to ensure that it cannot be turned on. This prevents unintentional energization while work is being performed.

Tagout: Use tags to communicate information about the equipment’s status. Tags should provide information about the reason for the lockout and who is authorized to remove it.

Verification: Before starting any work, always verify that the equipment is properly locked out and de-energized. This step ensures that the equipment won’t unexpectedly become energized during maintenance.

Proper Electrical Safety Measures:

In addition to LOTO procedures, there are other electrical safety measures that should be followed to prevent arc flash incidents:

Personal Protective Equipment (PPE): Properly selected and used PPE can significantly reduce the risk of injury in the event of an arc flash. PPE may arc rated clothing in accordance with IEC 61482-2, face shields and either composite or arc flash rated gloves.

Arc Flash Risk Assessment: Conduct an arc flash risk assessment to determine the potential energy levels and hazards associated with different electrical equipment. This assessment will help in determining the appropriate level of PPE and safety procedures for each situation.

Regular Maintenance: Ensure that all electrical equipment is properly maintained and inspected regularly. Damaged or worn-out components can increase the risk of arc flash incidents.

Warning Labels: Affix warning labels to electrical equipment indicating the potential arc flash hazard and the necessary PPE requirements.

Training: Provide proper training to workers on the hazards of arc flash, how to identify potential risks, and how to use LOTO procedures effectively.

Engineering Controls: Implement engineering controls such as arc-resistant switchgear and enclosures to contain or redirect the energy of an arc flash, reducing its impact.
