What is required for personal supervision according to fire safety regulations?

Personal supervision as mandated by fire safety regulations necessitates the presence of a certified individual at a designated location. This requirement ensures that there is an experienced and knowledgeable person on-site who can respond immediately to any hazardous situations that may arise, particularly concerning the use of flammable gases in laboratories. The presence of this certified individual enables effective risk management by allowing for direct and immediate intervention in emergency scenarios, as well as ensuring that all safety protocols are being adhered to during operations.

While other options may play a role in overall safety management, they do not fulfill the critical aspect of direct human oversight that is vital in environments where flammable gases are involved. Scheduled checks by safety officers, continuous monitoring by remote systems, and availability of written protocols can enhance safety practices but cannot replace the necessity for an actively supervising individual present in the area where potentially dangerous activities are taking place. This hands-on approach is key to mitigating risks associated with flammable materials.
