Indy100 contacted Wandsworth Council to try to shed some light on the types of emergency a "grab bag" might be useful for.
A spokesperson responded:
This is part of an annual national campaign, supported by many public bodies up and down the country, including councils, the NHS, police and fire services, and is aimed primarily at those in vulnerable situations who may need to leave their homes at a moment’s notice.
This includes people living in a flood risk area, victims of domestic violence or those who may be affected by a gas leak or a power cut. This national campaign simply urges people to be prepared for sudden emergencies.
