Our hazardous area exit signs are designed for locations that are prone to flammable dust, vapors, corrosion, liquids, saltwater, ice, vandalism and much more. The signs carry industry recognized ratings for example, food safety NSF, wet location as NEMA 4X or IP67 or industrial classifications for areas as class 1 div 1, class 1 div 2 or are marine certified. For situations where temperatures fall below freezing, for our electrical signs and lights we will include battery heaters and/or a battery blanket. We have models for every situation.
