Safety Data Sheets and Warning Signs

New! "Material Safety Data Sheets" are now known as "Safety Data Sheets"

Know the hazards associated with the materials you use! Always review chemical safety information, such as an SDS or other resource, before starting work with a new or unfamiliar chemical.

Safety Data Sheets (SDSs)

Safety Data Sheets (SDSs) provide necessary information about precautions for protecting against known hazards associated with the material and often include useful information on chemical, physical, and toxicological properties, along with suggestions for storing, transporting, and disposing of chemicals. SDSs are the best general source of information available, and they should be consulted as a first step in assessing the risk associated with doing an experiment or working with a new product. However, because there is currently no standard format for SDSs, their quality varies widely, and the information that they contain may be inappropriate for laboratory use. Exercise caution when using SDS's and use non-SDS sources for additional information. If you need additional assistance call EH&S at 9-2553.

UC Safety Data Sheet System

The University of California's Environmental Health and Safety Offices have combined efforts and resources to create a ‘one-stop’ source for SDS's and chemical safety information. This search engine will be growing as UC routinely adds major chemical vendors into its integrated database.

To access this UC SDS database you must be connected through a recognized UC campus computer.

Chemical Hazards Information

Micromedex is a commercial database that provides easy access to chemical hazard, environmental, toxicological and medical information needed for the safe use and management of chemicals. The UC EH&S Offices have obtained a site license for this excellent resource, and it is available to all main UC sites with UC IP addresses.

Warning Signs

Laboratory spaces where designated biological, chemical, or radiological materials are used or where potential physical hazards exist are posted with warning signs. Researchers, staff, and visitors should note and understand hazard communication information provided on the warning signs, including specific hazardous agents (biological, chemical, radiological) and physical hazards (lasers, magnetic fields) present and used in the space, stated precautions (no food or drink allowed), and required personal protective equipment (lab coat, eye protection, gloves, etc.)

GHS Symbols

The GHS (Globally Harmonized System) symbols were developed by the United Nations as a world-wide standardized system for the classification and labeling of chemicals. Click here to view the GHS symbols.

Laboratory Warning Sign Symbols

Biological Hazard

biohazard warning symbol

The biological hazard warning is used to identify locations, equipment or materials where infectious agents may create a health risk. It is used to identify specific equipment, containers, rooms, and waste items that are known or potentially contaminated with biohazardous materials.

Radioactive Material and X-Rays

radioactive material warning symbol

All areas where radioactive materials or x-rays are used are posted with this symbol. The symbol also identifies specific equipment, containers, rooms, and items that contain, or are potentially contaminated, with radioactive material.

Laser

laser warning symbol

The laser warning sign indicates the presence of a laser with enough power to cause injury to your eyes or skin. Do Not Enter a room with this symbol unless you are sure the laser is off. Do Not Enter a room if you cannot determine if the laser is on or off from the lighted warning sign outside of the lab.

High Voltage

high voltage warning symbol

Rooms or areas within rooms that contain high voltage equipment are posted with this warning sign. These areas can present significant hazards should a flood or water leak occur. Do not work on or handle open wiring or open devices that may be energized.

Strong Magnetic Field

magnetic field warning symbol

This warning sign is common in rooms with Nuclear Magnetic Resonance (NMR) machines. Do not approach the magnetic field area with metallic objects, including tools or equipment. 

No Pacemakers or Metallic Implants

pacemaker warning symbol

Individuals with pacemakers, other medical electronic devices or metallic implants MUST STAY OUT of areas with this warning sign. This warning sign is common in rooms with Nuclear Magnetic Resonance (NMR) machines.
