Final answer:
The specified maximum travel distance to the 2-A rated portable fire extinguisher for G-60 torch operations is crucial for safety and emergency responsiveness, but the exact distance is not provided in the question.
Step-by-step explanation:
The question pertains to the required safety measures for hot works performed by a G-60 torch operator, specifically regarding the necessary proximity of a portable fire extinguisher. The fire extinguisher with a 2-A rating must be available at a maximum travel distance that ensures prompt and efficient response in case of a fire. It is vital for such safety equipment to be easily accessible to ensure the safety of the operator and to minimize potential damage from any accidental fires. Knowing the location of safety equipment like fire extinguishers and eyewash stations is a crucial component of laboratory and workshop safety protocols. This rule ensures that in case of an emergency, such as an unexpected fire during hot works, the operator or the fire guard can quickly suppress the fire, thereby preventing harm to individuals and property.
