General office environment preparedness

FAK
A good bandaids & aspirin FAK for a small office shouldn't cost more than $300. Keeping it stocked might cost around $30 / month. You will be replacing antacids and aspirin way more than bandages. An advanced FAK isn't indicated unless you have some CPR trained folks and they are designated by and known to the entire office as the GO-TO medic. That title should come with perks if not pay. The advanced FAK might add cpr mask, Ambu-Bag, BP Cuff, Stethescope, AED, Oxygen and trauma bandages. The most likely use of the advanced FAK in the environment you describe would be for heart attack.

FIRE
You might want to supply yourself if not everyone with evac-u8 hoods. Fire would seem the most probable large-scale event you would want to prepare for. If there are openable windows (often there are in older buildings) you might think of storing escape ladders near the openable windows. You are only on the second floor and that would provide extra evacuation routes if the stairs are blocked by fire or smoke. These are fairly cheap insurance ~ $50 each.

Power Outage
Some of those plug-in emergency lights that store in the plug socket and light up when they aren't getting any power from the plug are cheap and very useful. If there is no emergency lighting already installed then these would be a decent item to place in each hallway or office for ~$20 per. Recommending flashlights to the residents is a waste of air. Often promotional gadget vendors will offer samples in the effort to get you to get something imprinted for mass mailing. There are cheap led keychain lights available throught that approach. If you had one for each employee they might put them on their keychain or they may throw them in their desk drawer - eitherway they might have one when the need it at work.
If you have battery backed UPS's for your PC's then someone needs to take the duty of checking the batteries once a month. If this isn't being done you probably don't really have UPS backup power but rather a large heavy heater that will be useless when called upon.
Same person should be checking fuel condition and supply and genset maintenance if you have that sort of power backup installed. A genset needs to be run for a few hours each month to stay usable.

General Maintenance
If you don't have a building maintenance contract or crew then you have a communal responsability to change the lightbulbs and refill the TP roll. If this isn't being shared and no-one has been designated then you have a political problem not a tool problem. That being said, tools for these sort of responsibilities should be provided by the person responsible. If that person is in the employe of the firm then the appropriate tools should be provided to them as needed.

PC Admin - maintenance.
See general Maintenance - same thing just different skills and tools.

Shelter
If there is any possibility that your office may become your home for a short duration because of whatever event that makes getting home or being home untennable and evacuation to better digs impossible then your office needs sheltering supplies.
Water - 1 gallon per person per day minimum, Blankets, Fuel powered heaters - alpaca kerosene stove is a great alternative, sanitation without plumbing - honey buckets are a possibility as long as you have a place to dump them once a day, Food - think vending full vending machine with three or four slots mandatorily taken up with granola bars, and pop-tarts or other "complete meal" alternatives in the eternal food category.

Just some thoughts. Probably won't get the firm to spring for the whole she-bang but if you are decent at Powerpoint proposals and do a thorough job of researching supplies and prices and options you could pitch it to the big honcho in the corner office as a good thing to consider and maybe get a decent Office FAK at least. There is good stuff at the FEMA site and the ARC site to start your research. If you do make a presentation I would love to see the finished product.

Heck for that matter, If anyone here has made a pitch like this to their firm before I would love to see the presentation and supporting documentation.
