Which of the following practices can enhance safety when working with LPG or CNG?

Regular training and emergency drills are critical practices that can significantly enhance safety when working with Liquefied Petroleum Gas (LPG) or Compressed Natural Gas (CNG). These practices ensure that individuals are familiar with the hazards associated with these gases and know how to respond effectively in emergency situations. Routine training helps reinforce knowledge about safe handling, proper use of equipment, and emergency protocols, which can prevent accidents and mitigate the effects of any incidents that may occur.

Emergency drills create a realistic environment where personnel can practice their response to potential emergencies, improving their readiness and confidence. This hands-on experience is vital in reinforcing safety habits and procedures, facilitating quick and efficient actions in a crisis. By integrating regular training and emergency exercises into the operational routine, workers are better equipped to recognize unsafe conditions and act decisively, which is crucial in maintaining safety when dealing with LPG or CNG.

Other practices, such as using manual start systems or minimizing personal protective equipment, do not necessarily enhance safety and can potentially create risks. Working alone in a controlled environment also undermines safety, as having colleagues present can provide support and additional oversight in case of an emergency.
