Blackouts, shortages & attacks
A free UK guide to surviving a national crisis — blackouts, solar storms, fuel and gas shortages, food imports cut off, cyber attacks on the NHS, banks, water and the grid, missile and drone strikes, and undersea cable sabotage: ten scenarios played out hour by hour, the first 72 hours, water, a family-of-four food stash (including gluten-free), staying warm, security, staying unseen, self-defence within UK law, car kits, grab bags, and whether to stay, move or leave the UK.
Pandemics & dangerous infections
A free UK guide to surviving pandemics and dangerous outbreaks — new viruses, highly contagious and slow-but-deadly infections, and deliberate release: how infections spread, masks and ventilation that work, isolating a household, and detailed home medical care for when health services are overwhelmed.

Make a donationWhy these guides
Figures come from primary and official sources — risk registers, health services, regulators and the scientific literature — and the sources are named in each guide.
UK law, UK weather, UK homes and UK services: from petrol-storage limits and knife law to gas boilers that stop in a power cut and when to call NHS 111.
Every guide prints to A4 with a pocket quick-reference, because in a real emergency you may have no power, no signal and no internet.
Questions
Yes, all of them. Read every guide online, or download the PDFs to keep. There's no sign-up, no email and nothing to pay. Donations are welcome but entirely optional.
Start with UK Crisis Survival: long power cuts, storms, fuel and supply problems, cyber attacks and strikes on infrastructure are the emergencies most likely to affect UK households, and its water, food, warmth, security and grab-bag advice applies to almost any emergency. Keep the Emergency Medical Survival guide with your first aid kit. Then read the guide for the specific threat you're most concerned about.
Each guide comes as two A4 PDFs: the full guide and a short pocket quick-reference — Nuclear Event Survival (88-page guide + 6-page pocket guide); UK Crisis Survival (81-page guide + 4-page pocket guide); Pandemic & Outbreak Survival (44-page guide + 4-page pocket guide); Emergency Medical Survival (86-page guide + 4-page pocket guide). Save them to your phone or computer and print them for your emergency kit, because in a real emergency you may not be able to get online.
Every figure and procedure is checked against primary and official sources — for example FEMA, the CDC, the WHO and the IAEA for nuclear events, and the UK National Risk Register, NESO, National Gas, the Met Office, Ofcom, the NHS, the National Audit Office, Defra, the Food Standards Agency and the HSE for the UK crisis guide. Sources are named in the guides, and they are updated as guidance changes.
Print as many copies as you need for yourself, your household and your emergency kit. To share, please send people the link to survivalmg.com rather than re-uploading the files, so they always get the latest version.
No. The guides are educational and summarise publicly available guidance. In a real emergency, always follow the instructions of the emergency services, the NHS and your local authorities.
