NFPA 704, the Standard System for the Identification of the Hazards of Materials for Emergency Response, outlines minimum text size requirements to ensure that NFPA 704 signs remain legible at long distances in order to keep emergency personnel safe. In addition to the viewing distance specifications, the standard also provides dimensions of each hazard rating number as it relates to the hazard rating quadrant surrounding it.
It is the responsibility of the end user to determine the viewing distance, and the correct size NFPA 704 sign necessary to alert emergency personnel at a safe distance. According to the NFPA 704 Standard, a ratio of 25 feet of viewing distance per inch of text should be used to determine the minimum text size required up to 100 feet. From 100 to 200 feet, a ratio of 100 feet per inch of text should be used, and from 200 to 300 feet, a ratio of 50 feet per inch of text should be used. The NFPA 704 Standard does not distinguish between favorable or unfavorable viewing conditions.

Using the latest digital printing technologies and processes, your NFPA Container Label has text and graphics printed directly onto the substrate without lamination. Using UV inks, your label text and graphics will not peel, unlike labels from companies that laminate graphics over the label material. These advanced practices also eliminate set-up charges and minimums. Your set-up time is also greatly reduced, allowing to print your NFPA Container Label quickly and have them shipped out fast.

Printing Methods

We choose our printing processes for each product carefully so you receive the best quality product at the lowest price with industry-leading turnaround times. Depending on your size, material, quantity, and other factors, your sign will print using one of our carefully-tested methods.

SafetySign Printing
Cross-Hatch Ink Adhesion Test’s advanced printing process undergoes a stringent cross-hatching test. This specifically tests the adhesion and resistance to separation of the inks from the sign. In testing, a sample from the printing process is scored and covered in adhesive tape. The tape is removed and the sample assessed for adhesion quality.

We use a three-stage process to test all of our printing processes. We print our signs using only the processes that pass all three stages, giving you the highest quality signage possible.

SafetySign Printing

The text is printed in Arial Black and Arial Condensed Bold fonts.

The NFPA Container Label from uses these fonts to create a bold message that stands out in order to grab your attention, while also allowing for a large word message that remains clearly legible.
