Is industrial injury and social security the same thing?

No. Social security is a social welfare system, including endowment insurance, medical insurance, industrial injury insurance, unemployment insurance and maternity insurance. Among them, industrial injury insurance is a part of social security, and necessary material assistance, such as compensation and medical expenses, is given to workers who suffer accidental injuries or occupational diseases at work, resulting in temporary or permanent loss of working ability and death. Therefore, work-related injuries and social security are not the same thing.
