Phosphate Global Harmonization Safety (GHS) Requirements

Carus blended phosphate products are part of the broad chemical category identified as “corrosion control and sequestering chemicals”.  These products are manufactured, packaged, and delivered in either a dry powder or a concentrated liquid form.

These two forms are similar in that the active ingredient, which is orthophosphate and polyphosphate, is the same regardless of the physical form of the product. However, they are different in the concentration of this active ingredient, varying from nearly 90% as a dry product, to 40% to 10% as a liquid solution. These changes in form and concentration drive the associated cautions about safe handling and use.

Regarding safety and handling of phosphate, the most important communication pieces we offer are Safety Data Sheets (SDS), formerly known as Material Safety Data Sheets (MSDS). The main change from MSDS to SDS includes the Globally Harmonized System (GHS) for Hazard Communication. Required in this change, for example, is a new 16-section format – although Carus has been using a 16-section MSDS for some time. For more information on what each section includes, check out the OSHA Hazard Communication Safety Data Sheets Quick Card.

When our phosphate products are stored and handled properly, they are stable and easy to use. Blended phosphates are not hazardous chemicals.  Under GHS, signal Words, hazard statements, and precautionary statements are new to phosphate labels.  These are included to better define the health and safety impacts of the product being used.

There are only two signal words to choose from under GHS: WARNING or DANGER.   Neither is used in the case of blended phosphate products.

The new hazard statement reflects the potential health hazards as well as the chemistry of phosphate. “This mixture does not meet the criteria for classification” is the designated hazard statement for phosphate.

Below are the new precautionary statements for phosphates. The wording is specific to phosphate and linked to the physical hazards associated with them.

·         Prevention: Observe good industrial hygiene practices.

·         Response: Wash hands after handling.

·         Storage: Store away from incompatible materials.

·         Disposal: Dispose of waste and residues in accordance with local authority requirements.

For more in-depth information on safety and handling of phosphates, please register for our upcoming webinar.  In addition to GHS requirements, this presentation will cover the storage and safe handling of phosphate products ranging from orthophosphates and zinc orthophosphates to liquid blended poly/ortho phosphates.  Topics will include chemistry, material compatibility, storage, handling, proper PPE, and disposal of phosphate-based products. We also have the following document available regarding our blended phosphate compatibility information.
