What label must be on any compressed gas cylinder brought to a Sobeys store by an outside service technician who is fixing one or more of their refrigerated/freezer units?

The correct label that must be on any compressed gas cylinder brought to a Sobeys store by an outside service technician is a supplier label with a black and white border. This requirement aligns with the standards set for handling hazardous materials, particularly compressed gases. The supplier label serves as a crucial source of information about the gas contained within the cylinder, including its identity, hazards, handling precautions, and emergency measures.

Supplier labels typically follow specific visual and informational criteria set by regulatory bodies to ensure that they clearly communicate the necessary safety information. The black and white border is a recognized feature that helps distinguish these labels from others, enhancing visibility and ensuring that employees can quickly identify the hazards associated with the gas. This is particularly important in a setting like a Sobeys store where food safety and employee safety are top priorities, as any mishandling of gases could lead to serious incidents.

In contrast, workplace labels or manufacturer labels may not meet the specific safety standards required for compressed gases used in commercial settings. These labels might lack the necessary information or formatting to be compliant with local regulations on the safe management of hazardous materials, including compressed gases.
