NFPA Diamond 3-0-2 for Acid, Sulfiric Acid, No Water
This NFPA Diamond 3-0-2 provides proper safety and hazard identification of sulfuric acid, corrosive acids with how they are handled, or stored.
As an highly corrosive chemical, it is important to take extra precautions when handling and storing sulfuric acid.
This NFPA Diamond 3-0-2 printed on adhesive vinyl. The vinyl has a durability rating of up to six (7) years. Note: The durability will depend on the elements, any corrosive liquids making contact etc. We use resin inks not water based or other solvent based making our product more durable.

What is NFPA 704?
NFPA 704 is the standard that is intended to provide a simple, readily recognized, and easily understood system of markings. These markings will provide a general idea of the hazards of a material and the severity of these hazards as they relate to emergency response.
In more specific terms the objectives of the system are to:
- To provide an appropriate signal or alert and on-the-spot information to safeguard the lives of both public and private emergency response personnel
- To assist in planning for effective fire and emergency control operations, including cleanup
- To assist all designated personnel, engineers, and plant and safety personnel in evaluating hazards
The system shall also enable fire-fighting, emergency, and other personnel to easily decide whether to evacuate the area or to commence emergency control procedures. It shall also assist those personnel in selecting fire-fighting tactics and emergency procedures.
Where do I need to post NFPA 704 signs?
Signs shall be in locations approved by the authority having jurisdiction and as a minimum shall be posted at the following locations:
- Two exterior walls or enclosures containing a means of access to a building or facility
- Each access to a room or area
- Each principal means of access to an exterior storage area
What do the colors and ratings in each diamond mean?
Blue - Health Hazard Rating
This relates to the capability of a material to cause personal injury due to contact with or entry into the body via inhalation, skin contact, eye contact, or ingestion. All ratings are determined under emergency conditions.
| Rating | Description |
|---|---|
 |
Materials that can be lethal |
 |
Materials that can cause serious or permanent injury |
 |
Materials that can cause temporary incapacitation or residual injury |
 |
Materials that can cause significant irritation |
 |
Materials that would offer no hazard beyond that of ordinary combustible material |
Red - Flammability Hazard Rating
This relates to the degree of susceptibility of materials to burning.
| Rating | Description |
|---|---|
 |
Materials that rapidly or completely vaporize at atmospheric pressure and normal ambient temperature or that are readily dispersed in air and burn readily |
 |
Liquids and solids (including finely divided suspended solids) that can be ignited under almost all ambient temperature conditions |
 |
Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur |
 |
Materials that must be preheated before ignition can occur |
 |
Materials that will not burn under typical fire conditions |
Yellow - Instability Hazard Rating
This relates to the degree of hazard due to reaction with ambient air, light, or both, and the degree of intrinsic susceptibility of materials to release energy by self-reaction or polymerization.
| Rating | Description |
|---|---|
 |
Materials that can be lethal |
 |
Materials that can cause serious or permanent injury |
 |
Materials that can cause temporary incapacitation or residual injury |
 |
Materials that can cause significant irritation |
 |
Materials that would offer no hazard beyond that of ordinary combustible material |
White - Special Hazards
This area of the diamond shall address water reactivity and oxidizing properties of the materials that cause special problems or require special fire-fighting techniques.
| Rating | Description |
|---|---|
OX |
Material possesses oxidizing properties |
SA |
Material is a simple asphyxiant |
 |
Material that reacts violently or explosively with water |
Non-Standard Special Hazard Symbols
These special hazard symbols and others are not part of the NFPA 704 standard, but may be used if permitted by the authority having jurisdiction.
| Rating | Description |
|---|---|
ACID |
Material is an acid |
ALK |
Material is a base (alkali) |
COR |
Material is corrosive |
CRY |
Material is cryogenic |
POI |
Material that is poisonous |
 |
Material is radioactive |
