Hazardous Materials Labeling Training - GHS, HMIS and NFPA Labels

Hazardous materials come in many forms, and no two can be handled exactly the same way. Knowing how to quickly read and interpret hazmat labels is one of the most critical skills for anyone who works around dangerous substances. This course explores the major labeling systems used in the workplace and how to use them to identify hazards, take the right precautions, and stay safe on the job.

Course Highlights

• Overview of the key government agencies — OSHA, DOT, and EPA — that regulate hazardous materials labeling and what each agency requires
• Introduction to the Globally Harmonized System (GHS), including its nine hazard class pictograms, signal words, hazard statements, and precautionary information
• Breakdown of the Hazardous Materials Identification System (HMIS), including its color-coded categories for health, flammability, reactivity, and personal protective equipment (PPE)
• Explanation of HMIS hazard severity numbers (0–4) and how they communicate the level of risk associated with a substance
• Guide to NFPA diamond-shaped labels, including how to read the four color-coded quadrants and identify special hazards such as radioactive materials, water-reactive substances, and oxidizers
• How to recognize chronic health hazard indicators, target organ information, and special handling requirements on HMIS labels
• Common labeling requirements that apply across all systems, including legibility, prominent display, and firm attachment to containers

By the end of the course, you will have learned

• Why hazardous materials labels are a critical source of safety information and how they are regulated by OSHA, DOT, and the EPA
• How the GHS classifies hazardous materials and what each label element — pictogram, signal word, hazard statement, and precautionary information — communicates
• How to read HMIS labels, including the meaning of each color-coded category and the 0–4 hazard rating scale
• How to identify the appropriate PPE for a hazardous material using the letter or pictogram codes found on HMIS labels
• How to interpret NFPA diamond labels, including flammability, stability, health hazard ratings, and special hazard icons
• The differences and similarities between GHS, HMIS, and NFPA labeling systems and when each is used
• How to use hazmat labels to make informed, safe decisions when working with or around hazardous substances
