There are three emergency plans now.
Comprehensive emergency plan, special emergency plan and on-site disposal plan
Comprehensive emergency plan: it is generally a general procedural document, usually with only one unit.
Special emergency plan: formulate prevention, control and emergency measures according to different risks. Generally, it is divided into four categories: industrial production, natural disasters, public health and social security.
On-site disposal plan: generally connected with special plan. Specific emergency actions
The occupational health you refer to belongs to the special emergency plan of public health. There should be different special plans for different occupational health accidents, such as poisoning, suffocation and heatstroke. Therefore, it is not recommended to have only one occupational health emergency plan in the occupational health emergency plan, but to divide it into different special plans and formulate corresponding on-site disposal plans to form an occupational health emergency plan.
Therefore, the occupational health emergency plan is a public health plan in the special plan, not a comprehensive emergency plan.
According to your own question, what is a comprehensive emergency plan is to choose words. Mainly the understanding of the word "comprehensive". In a narrow sense, it is composed of several special emergency plans. If it is a comprehensive plan, of course. But there is no such expression in the emergency plan system, only the term comprehensive emergency plan.
