The Annexes of NFPA 70E can be very useful. We previously addressed the first eight. Here's an overview of the next four.
Annex I — Here, you’ll find a sample job briefing and planning checklist. It consists of six sections: Identify, Ask, Check, Know, Think, and Prepare for an emergency.
Annex J — This resource contains a sample energized work permit and a flow chart that provides a decision-making process for producing a work permit that will help achieve the desired outcome. That outcome is, as the final box of the flowchart says, “Proceed to work safely.”
Annex K — Electrical hazards can be divided into three general categories. Do you know what they are? This annex names them and provides some information on each one. If you’ve read this annex, you won’t be surprised to know that the majority of hospital admissions resulting from electrical accidents are not from electrical shock (one of the three categories).
Annex L — Electrolytic lines present their own set of hazards, and this annex addresses the application of safeguards against those hazards. It names seven specific safeguards for working on these lines.
