Full definition
The complete system of visual signs, labels, floor markings, and pipe identification in an industrial facility that communicates hazards, required behaviors, prohibited actions, evacuation information, and zone identification to workers and visitors. Per NOM-026-STPS-2008 (Mexico) and ANSI Z535 (US): safety colors — red (prohibition/fire), yellow (caution/warning), green (emergency/safe condition), blue (mandatory action); these are consistent across ISO 7010, ANSI Z535, and Mexican NOMs. Beyond safety signs, industrial signage includes: (1) Pipe identification per ANSI/ASME A13.1 — color bands and text identifying pipe contents (water, steam, compressed air, chemicals, fire protection). (2) 5S/lean zone markings — floor tape demarcating work areas, walkways (green/yellow), material storage (blue), and hazard zones (red). (3) Machine and equipment labels — operating instructions, weight limits, maintenance schedules. (4) Chemical labels per GHS — product identifier, hazard pictograms, signal word, hazard/precautionary statements. (5) Electrical danger labels — arc flash labels per NFPA 70E/IEEE 1584. (6) Lockout points — identification of all energy isolation points per LOTO program. Per NOM-026-STPS, ANSI Z535, ISO 7010, and OSHA 29 CFR 1910.145. A well-signed facility reduces accidents, improves emergency response time, and demonstrates regulatory compliance during inspections.
