GHS LabelsUPDATE: In 2012, the US Occupational Safety and Health Administration has updated the Hazard Communication standard to conform to a globally harmonized system of classification and labeling of chemicals. All employees who previously received hazard communication training will need to receive update training explaining the changes to manufacturer labeling and Materials Safety Data Sheets (now simply called Safety Data Sheets).

HMIS Label

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 documentation below) describing implementation of the Hazard Communication 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 MSDSs and labels used at TWU, proper handling of chemicals, and incidental spill cleanup.

Material Safety Data Sheets

MSDSs for chemicals stored or used on campus can be found the web-based TWU MSDS database.  Faculty, staff, and students receiving or bringing chemicals on site must retain the MSDS, and forward a copy to Risk Management for inclusion in this MSDS database.  Paper copies of MSDSs may also be maintained in various department offices and laboratories on campus.

Container Labeling

TWU uses the third edition of the Hazardous Materials Identification System (HMIS III) for labeling of 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 MSDS.

HMIS Guide

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.
