Hazard Communication

Graph with warning, danger, signs and symbols.

TWU is committed to ensuring that all faculty, staff, and students working with or around chemicals are informed of the specific physical and health hazards of those chemicals, and are protected against their hazards. This will be accomplished through training, the use of Safety Data Sheets (SDSs), and container labels. TWU has developed a written program (see the documentation below) describing the implementation of the Hazard Communication Program on campus in more detail.


All employees must receive training to become knowledgeable about the potential hazards of the materials they use and how to properly handle workplace chemicals. The training will include specific information about the potential health and physical hazards of chemicals, and measures to protect yourself from these hazards. The training will also cover information on how to read and understanding SDSs and labels used at TWU, proper handling of chemicals, and incidental spill cleanup.

Safety Data Sheets (SDSs)

SDSs for chemicals stored or used on campus can be found in BioRAFT. Faculty, staff, and students receiving or bringing chemicals on-site must retain the SDS, and forward a copy to EH&S for inclusion in this database. 

Container Labeling

TWU uses the third edition of the Hazardous Materials Identification System (HMIS III) for labeling containers that are not already labeled by the chemical manufacturer. The HMIS system provides a simplified system allowing employees to understand the primary risks of a chemical quickly but does not substitute for reading the SDS.

Chemical hazards laboratory settings are also covered by the Hazard Communication Program, however, the labeling requirements are somewhat different as per the TWU Chemical Hygiene Plan.
