Caution Signs are required to be posted at the entrance to a space where hazardous materials are stored or used. The Caution sign is based on a location's chemical inventory; it alerts emergency responders and visitors of potential hazards and precautions for entry.
Warning Signs alert personnel and visitors to health and safety hazards beyond those identified in the caution sign. Specific warning signs may be required based on the type of hazard present.
The NFPA hazard rating system refers to a safety standard by the National Fire Prevention Association (NFPA) that outlines a hazard rating system for emergency personnel.
The NFPA 704 standard also defines the necessary signage and information that needs to be displayed to alert personnel of the type of hazardous materials that are present.
The Incompatible Chemicals Focus Sheet contains a Chemical Compatibility Chart chart adapted from the CRC Laboratory Handbook which groups various chemicals into 23 groups with examples and incompatible chemical groups.
This chart is by no means complete but it will aid in making decisions about storage.
For more complete information please refer to the MSDS/SDS for the specific chemical.
