To reduce the potential losses resulting from fires, a chemical manufacturing company implemented the following safety measures in its warehouses: the establishment of additional escape and shelter areas； Add exhaust fans ； Set up a firewall ； Equipped with fire emergency respirators. Among the safety technical measures adopted by the following enterprises, which ones follow the appropriate priority order for preventing accidents and reducing the losses resulting from them? A. Install a firewall → Add smoke exhaust fans → Provide emergency fire respirators → Add escape and shelter areas. B. Add escape and shelter areas → Install a firewall → Add smoke exhaust fans → Provide emergency fire respirators. C. Add smoke exhaust fans → Install a firewall → Provide emergency fire respirators → Add escape and shelter areas. D. Provide emergency fire respirators → Add escape and shelter areas → Install a firewall → Add smoke exhaust fans. Answer: C. Explanation: (I) Safety technical measures to prevent accidents: (1) Eliminate hazard sources. (2) Restrict energy or hazardous substances. (3) Isolation. (4) Fail-safe design. (5) Reduce failures and mistakes. (II) Safety technical measures to reduce accident losses (1) Isolation. (2) Identify weak links. (3) Personal protection. (4) Encounters with difficulties and rescue. Installing additional exhaust fans can reduce the amount of toxic and harmful gases at a fire scene, thereby serving to limit the energy or hazardous substances involved in preventing accidents ； Set up a firewall: Installing a firewall can prevent the spread of fire, serving as a containment measure to reduce losses from accidents ； Equipping with fire emergency respirators is an individual protective measure to reduce losses from accidents ； Establishing additional escape and shelter areas is a sheltering and rescue measure to reduce losses from accidents ； Following the order of preventing first and then reducing, the correct answer for this question is C
C. Install additional smoke exhaust fans → Set up firewalls → Provide emergency breathing apparatus → Create additional escape and shelter areas
C 『Answer Explanation』This question tests safety technical measures. Installing additional exhaust fans can reduce the amount of toxic and harmful gases at the fire scene, and it is a safety measure to eliminate sources of danger. Setting up a firewall: Installing a firewall helps prevent the spread of fires; it is an isolation measure among the safety technical measures taken to avoid accidents. Equipping with fire emergency respirators is an individual protective measure to minimize accident losses. Creating additional escape and shelter areas is a measure for sheltering and rescue aimed at reducing losses from accidents; following the principle of preventing incidents first and then minimizing their impacts, the correct answer in this case is C.
C. Install additional smoke exhaust fans → Set up firewalls → Provide emergency breathing apparatus → Create additional escape and shelter areas
