Emergency plans Wouldn't the point be to look at your business and think through how you would deal?
Some ideas from someone who has been living this in the last week... I have no idea if you are rural or city, so take what is useful and leave the rest :) I can only speak to our situation.
Biggest challenges here have been - lack of coms, lack of usable roads/bridges, lack of power, damage to houses and sections and infrastructure. My town has been super lucky that we have had drinking water and sewerage right through. There is the first day challenge, then as the days go by the challenges change.
Maybe rename your 'evacuation procedure' to a 'communication procedure' and see if that changes anything.
1. how do you know everyone is safe when you have no mobile coverage? When celltowers fail, normal coms don't work. It can be days.
2. how do you deal if there is a slip, road closure, flood waters, bridges out between where your people travel? What do they have in the vehicle that will help them and others near them? eg. First aid kit + training. Does every driver know not to drive in flood waters, and how high is too high etc.
3. What are the alternate routes and safe spots? What routes would people need to go to get home. Where can people go if they can't go home?
4. What back up power do you have at the shed? Charged battery packs, maybe alternate simcards. Spare petrol/diesel. Where is your nearest generator if you needed one, and spare cables? Camping stove with gas for hot drinks. Is the shed the best place to keep this (eg. evacuation point) or could you rustle it up from someone's house.
5. Can you take a laptop somewhere else so you can still deal with admin elsewhere. Is it backed up? Do other people know the passwords to deal with stuff if needed? (a data evacuation procedure lol). Everyone needs to know about whether their pay will go through.
6. Maybe a facebook messenger group or similar to get messages to and from staff quickly. Send test alerts to make sure all staff can access it. Best coms last week on spark were texts and facebook messenger. Other stuff simply didn't load for days. lets not talk about vodafone.
7. back up water. if you are rural, you may lose water pumping and clean water. Stash of muesli bars and biscuits that are checked.
That is all I can think of for now, please excuse the braindump.
