Core Viewpoint - The article emphasizes the increased demand for gas during winter and highlights the associated safety risks, particularly carbon monoxide poisoning and gas leaks, urging both households and restaurants to adopt proper gas usage practices [1][2]. Group 1: Household Gas Safety - The main safety hazards in household gas usage during winter are insufficient combustion and poor ventilation [1]. - The use of direct exhaust water heaters is dangerous as they lack a proper exhaust system, leading to indoor gas exposure; these products are now banned, and households still using them should replace them promptly [1]. - Improper installation of gas water heater exhaust pipes can cause backflow of exhaust gases into the home; regular checks and corrections by gas companies or professionals are necessary [1]. - The use of incompatible "energy-saving products" can lead to incomplete combustion and carbon monoxide production, posing significant risks [1]. - Insufficient indoor ventilation during winter can lead to carbon monoxide buildup; proper ventilation is essential, and any abnormal flame color should prompt immediate action [1]. Group 2: Restaurant Gas Safety - The restaurant industry has high gas consumption and usage frequency, necessitating strict adherence to gas safety protocols [2]. - Establishing a robust gas safety management system with designated personnel and regular employee training and emergency drills is crucial [2]. - Restaurants must avoid using "black gas" and ensure the use of legitimate gas sources, reporting any illegal activities related to gas supply [2]. - Ensuring the safety of gas facilities includes proper installation of gas alarms and automatic shut-off devices, with regular testing and maintenance [2]. - Key winter gas usage reminders include avoiding dangerous gas appliances, maintaining good ventilation, and conducting regular equipment checks [2].
