GHS & TDG Chemical Segregation & Storage

Under the Globally Harmonized System (GHS), chemicals should be segregated and stored based on their GHS hazard classes. Chemical segregation is necessary to prevent incompatible substances from coming into contact and creating dangerous reactions. In Canada, the Transportation of Dangerous Goods (TDG) regulates safe transportation of dangerous goods. The dual framework of GHS and TDG underscores the multifaceted approach required to manage chemical hazards comprehensively.

Proper segregation and storage practices play a crucial role in mitigating risks associated with chemical handling. Implementing storage considerations not only enhances workplace safety but also contributes to environmental protection.

Frequently Asked Questions About Chemical Segregation & Storage

What are Dangerous Reactions?

Dangerous or violent reactions include the following: 

  • Combustion or the release of substantial heat. 

  • Emission of flammable, corrosive, toxic, or asphyxiant gases. 

  • Creation of corrosive or unstable substances. 

  • Neutralization, resulting in the generation of corrosive mists or heat. 

  • Violent decomposition, exemplified by explosives. 

  • Polymerization accompanied by the release of heat, an increase in volume, and the potential rupture of the container. 

When Do Dangerous Goods Need to Be Segregated?

Segregation of dangerous goods may be necessary under the following circumstances: 

  1. When the means of transport, such as a vehicle, is set to be loaded with multiple types of dangerous goods, creating a "mixed load." 

  1. When packages are intended to contain more than one type of dangerous good. 

Do All Dangerous Goods Need to Be Segregated?

The simple answer is no. Segregation is required solely for dangerous goods exhibiting instability, violent decomposition, or potential hazardous reactions. Typically, goods with unstable characteristics are prohibited from being transported together in a mixed load or within the same packaging. 

Are There Specific Storage Requirements Outlined by the GHS & TDG?

The GHS provides general guidelines for storage conditions based on the hazard class of chemicals. Additionally, TDG regulations dictate specific requirements for the transportation of hazardous materials. This includes proper packaging, labeling, and segregation during transit. Chemicals must be transported in accordance with their GHS hazard class, and compliance with TDG regulations ensures the safety of both the transporters and the public. 

Are Chemical Storage & Segregation Training Programs Available?

Employees can be trained to follow GHS and TDG guidelines through dangerous goods training programs. Chemscape offers programs that cover the identification of hazard classes, proper labeling, and safe storage practices. Regular updates and refresher courses are essential to ensure that employees stay informed about the latest guidelines and regulations. 

Manage Chemical Hazards with Chemscape

Chemscape recognizes the importance of protecting workers from hazardous chemicals. To determine whether the chemicals you are storing are dangerous, it is recommended that you check the chemical manufacturers Safety Data Sheet (SDS) for specific details. The proper segregation and storage of chemicals under GHS and TDG regulations are integral components of a comprehensive approach to chemical safety.
