The proper use of personal protective equipment (PPE) is a critical component of any electrical safety program, and yet proper PPE use often is overlooked, diminished, or simply disregarded by electrical workers in manufacturing. Plant Engineering will present a Webcast on December 5th at 1 p.m. CT that will discuss the importance of PPE to mitigate arc flash dangers and other electrical safety issues.

Notes de l'éditeur
- Normally flammable liquids and gases should not be used around electrical equipment.
- [Read slide.]You may be involved in conducting audits at your location. Audits help verify what procedures work and where more training is needed. It is also a good idea to get someone outside of your department or even from outside of your location or company to participate in an audit. An outside perspective is a good way to catch holes or weakness in safety practices. EXPERT: Best practice companies follow this routine - Electrical audit one year by in-house person from your plant; next year audit by having another plant person audit your plant and you audit theirs. This cross-pollinates within the company and raises everyone’s skills. Third year, hire an outside auditor. Some companies give a little more time to correct things from an outside auditor or require the plant to justify in writing to the corporate auditor why they disagree with or cannot do what the external auditor suggested. This type of audit program can change a company throughout all its plants in many positive ways.Annual auditing of the qualified workers individually, the written ESP every three years and an annual general audit of safe practices has really been the intention of the committee for quite some time.

- Continuously monitoring your programs is essential to their successes. Research proves that both training and auditing improves safety; and, they go hand-in-hand. Audits are critical to verifying not only that new training skills are put to use, but that they are working for your facility. Audits also let your facility identify weakness and get an action plan in place before an injury occurs.EXPERT: The study cited showed in general safety (hard hat and safety glasses) that compliance to rules was about 65% before any training. Training increased the compliance to about 70%. Auditing increased the results to about 78% BUT re-communication of the audit results made compliance soar to about 95%. Management commitment AND measurement increases compliance much more than just training alone.
