The ABC London event company has taken measures to prepare for rain, but despite these efforts, the risk of natural calamities cannot be entirely eliminated. The company also faces risks related to health, equipment failure, and injury/accidents when organizing an outdoor event in Royal Park. These risks include exposure to bugs, sunburn, and frostbite, as well as potential diseases. Additionally, there is a risk of equipment failure due to lack of proper connections, and the possibility of injuries or accidents occurring due to incidents such as tree falls. Despite these risks, it is suggested that the company organize the fundraising event in Royal Park, citing benefits such as no restrictions on space availability, allowing for seating arrangements for large numbers of people.
