Does the country have laws, regulations, policies or documents that require employers in high-risk industries (such as security guards) to buy personal accident insurance for workers?

The state only has mandatory requirements for general, three risks or five risks. For security posts or long-term business trips, companies generally buy a commercial insurance from insurance companies alone. This kind of commercial insurance is not compulsory, which means that some companies are more formal, afraid of accidents and take too much risk, so they will buy commercial insurance. Some private companies, small and informal, will not buy these commercial accident insurance.
