GHS Hazard classes

 GHS hazard classes standardize classification procedures; chemical substances and mixtures that fulfil specific criteria, become associated with a specific hazard class based on its nature of being a physical, health, or environmental hazard. U.N. appointed task forces (OECD, UNCETVG/ILO) use their expert judgement to examine the scientific basis of the criteria defining the several GHS hazard classes. Based on the 6th revised edition of the GHS Purple Book there are a total of 29 hazard classes 17 of which are physical hazards, 10 health, and 2 environmental. The specific hazard classes for each type of hazard are listed in the charts below.

Testimonial

We help US and International clients prepare their chemical packaging labeling for marketing success in Canada. It has been my pleasure to work with Nexreg for the last 2 years on many domestic and international jobs. They have provided my company, and my clients, with CCCR determination and other product assessments in a timely, professional and forthright manner. Their employees, such as James Dayus, have been proactive, professional and personable. I trust them to talk directly to my clients and they have never let me down on professional document completion or deadlines. They are great to work with and I wholeheartedly endorse their work.
