What is ISO 14620-2:2019- Safety requirement launch site operations about?  
ISO 14620-2 specifies requirements for the safety liabilities of countries undertaking space activities or allowing operators to perform space activities on or from their territory under outer-space treaties adopted by the United Nations. It defines the safety responsibilities for the operators involved in commercial or non-commercial space launch activities. ISO 14620-2 establishes the overall safety requirements to be observed on a launch site for prelaunch (integration, test, checking, preparation, etc.) and launch operations of a space object. It provides the basic principles to enable an operator to implement its own safety methods, tools, and procedures to ensure the safety of people and personnel, public and private property, and the environment, in a consistent and uniform manner.
The safety requirements for system safety are defined in ISO 14620-1, and the requirements for the flight safety systems in ISO 14620-3.

Why should you use ISO 14620-2:2019- Safety requirement launch site operations?  
Space activities, carried out within the framework of outer space treaties adopted by the United Nations, may cause harm to people and create damage to public and private property and the environment.
The variety of professional disciplines linked to space activities and the legal liabilities incumbent on countries require international regulations to protect Earth populations against the consequences of a possible mishap caused by these activities. The international treaties listed in Annex A of ISO 14620-2 define the liabilities for damage related to space activities.
ISO 14620-2 pertains to exposed people (including populations and personnel), launch systems, manned or unmanned space vehicles, operations carried out on or from a launch site and associated procedures, natural environment, etc., during prelaunch (integration, test, checking, preparation, etc.) and launch activities.
ISO 14620-2 is intended to be applied by any country, by any international organization, whether governmental or non-governmental and by any operator undertaking space activities within the framework of outer space treaties adopted by the United Nations.
ISO 14620-2 is intended to be applied by agencies, enterprises, manufacturers, customers, designers, operators, facility authorities, launch service providers, etc., participating in the activities carried out on or from a launch site, unless more restrictive requirements are imposed by the national regulations in effect on the launch site.
