What is the maximum combined total NEW (Net Explosive Weight) in pounds for which an OSI must be designated?

The designation of an Operating Safety Instruction (OSI) relates to the management and oversight of explosives, which is critical for safety during handling and storage. The maximum combined total Net Explosive Weight (NEW) for which an OSI must be designated is set at 200 pounds. This standard helps ensure that proper safety protocols are in place when dealing with explosives, as higher quantities increase the potential risk.

Having a designated OSI for amounts at or below 200 pounds enables personnel to adhere to specific operational safety measures intended to mitigate risks associated with explosive materials. This designation is essential for maintaining compliance with safety regulations and protecting personnel and property from accidents related to explosive handling.

Understanding the significance of the 200-pound limit underlines the importance of careful management and training when working with explosives, ensuring that personnel are educated on appropriate emergency procedures, storage guidelines, and handling requirements when dealing with explosive materials.
