Half a year B. 1 year C. 2 years D. 3 years E. 4 years Article 22: Enterprises that produce or store hazardous chemicals shall entrust an institution with the **required qualifications to conduct a safety assessment of their safety production conditions every 3 years, and submit a safety assessment report. The content of the safety assessment report should include a plan for addressing the issues existing in the conditions for safe production. Enterprises that produce or store hazardous chemicals shall submit the safety assessment report as well as information on the implementation of the corrective action plans to the local county-level work safety supervision department for record-keeping. Enterprises that store hazardous chemicals within the port area shall submit the safety assessment report as well as information on the implementation of the corrective action plans to the port authorities for record-keeping. 　　2. According to the Code for Fire Protection Design of Buildings, the fire hazard classification for the coal-fired boiler room of this enterprise is (　D) 　A. Class A B. Class B C. Class C D. Class D E. Class E. Based on the Code for Fire Protection Design of Buildings, the appropriate fire hazard classification for boiler rooms is Class D: those that use gases, liquids, or solids as fuel for production ； 　　3 The pre-job safety training that employee A must receive upon being rehired by this company shall cover no less than (E) hours. 　　A.16 B.24 C.32 D.48 E.72 Basis: The \"Regulations on Training in Production and Business Operations\" (Order No. 3 issued by the General Administration in 2006) require that safety training for new operators handling hazardous chemicals must last at least 72 hours ； 　　 　　4 The possible accidents that could occur in this company’s warehouse are (A, B, C, E). A. Toluene fire B. Toluene explosion C. Toluene poisoning D. Asphyxiation due to toluene E. Xylene poisoning. Common asphyxiating gases can be divided into two categories based on their mechanism of action: simple asphyxiating gases and chemical asphyxiating gases. Simple asphyxiating gases typically include methane, carbon dioxide, and inert gases; they are either non-toxic or have very low toxicity. Their danger lies in the fact that their presence in the air reduces the oxygen level, leading to asphyxiation when inhaled. Chemical asphyxiating gases include carbon monoxide, hydrogen sulfide, cyanides, etc. When inhaled, these gases cause specific chemical reactions in the blood or tissues, disrupting the blood’s or tissues’ ability to carry oxygen. This affects the delivery of oxygen to the tissues and their metabolic processes, resulting in cell hypoxia. Such gases are more dangerous than simple asphyxiating gases. Toluene, being toxic, cannot be considered an asphyxiating gas ； 　　5. Based on the production status of this enterprise, which of the following statements is correct? (　) 　　A. The number of employees in this enterprise is less than 300, so it is not necessary to establish a safety management department or assign full-time safety officers (BD). 　　B.
