AFH labeling typically refers to Arc Flash Hazard (AFH) labeling, which is used to warn individuals about the potential hazards of arc flashes in electrical equipment. These labels are crucial for safety and compliance with standards like NFPA 70E and OSHA. They indicate the potential incident energy and required personal protective equipment (PPE).
Do….👍
Do label “WORST” case energy or PPE level. Consider all possible modes of operation.
Do label per as per Country Standards i.e. Eg. ANSI Z535.4 etc.
Do label using only one color, Orange for Warning or Red for Danger.
Do standardize on only one working distance – preferably 18 inches for all labels in a facility.
Manage down PPE levels using work permits stating increased distances based on work task and proper safety procedures.
Label to warn of potential danger, not for the purpose of working on the equipment.
Do use common sense in your hazard labeling.
Do implement NFPA 70E Article 130.1 work permit requirements for all energized work even if a label is present.
Don’t…👎
Do not label each MCC bucket, breaker/fuse cubicle, or plug-in (busway).
Do not label using colors for PPE level.
Don’t label with multiple distances or PPE levels on the same equipment.
Don’t make it complicated.
Don’t substitute labeling for NFPA 70E Article 130.1 work permit requirements.
