The DANGER signal word is not interchangeable with WARNING or CAUTION. It means the hazard in consideration can cause severe injury or death if someone gets it wrong. A general chemical hazard sign covers a broad category. A Chemical Danger sign tells workers this specific area or substance is at the serious end of the scale and needs to be treated accordingly.

Highly toxic substances, concentrated acids and bases, flammables with low flash points, and oxidizers that react violently on contact. When in doubt, pull the Safety Data Sheet; the hazard classification in Section 2 will tell you what signal word is appropriate.

On storage cabinets and containers, at chemical room entrances, on process equipment, near dispensing and mixing stations, and on tank exteriors. The sign should be easily visible to workers before they are already in contact range.

OSHA 29 CFR 1910.1200 (Hazard Communication Standard) requires employers to communicate chemical hazards clearly. OSHA 29 CFR 1910.145 covers accident-prevention signs and tags. For large-volume storage, EPA 40 CFR Part 68 under the Risk Management Program may also apply.

Naming the chemical provides workers more clarity to work with. A general Danger sign works for mixed-chemical storage areas. Either way, individual containers still need their own GHS-compliant labels. The area sign and the container label are doing two different jobs.

Yes. Pairing a chemical danger warning with a PPE reminder on the same sign or directly alongside it is one of the most practical approaches. In one glance they have both the warning and the next step right there.

The signs come in different sizes. Some common sizes for hazard signs are 3.5" x 5", 5" x 7", 7" x 10", 10" x 14" These sizes ensure that the signs are visible and easy to read. These signs need to be big enough to grab people's attention and small enough to fit in the space available.
