Вчера целый вечер занимались этим:

I Broke a Fluorescent Lamp. Now What?

Open doors and windows in the area to allow any mercury vapor to start dispersing from the immediate area. If other areas of the building can be closed-off, close them off. TURN OFF AND LEAVE OFF any window or central air conditioner blowers and ceiling fans, as the mercury may condense in the air ducts or coils of these units or spread the contamination to other areas. Allow outdoor air flow to clear the air for an hour at least. (A box fan positioned in a window or door that is pushing air into the room from the outside can help speed the process. Don't use the fan to blow air already in the contaminated room anywhere else.)

Any bleeding injuries should be treated immediately since many of the phosphors used in lamps can prevent blood from clotting and impair healing. Any skin or eye contact with phosphor should be washed with water for at least 15 minutes, unless the eye was actually cut by glass. If an eye injury occurred, ask emergency personnel how to proceed, as washing with water might cause more problems. All contaminted clothing and shoes must be removed prior to leaving the area. Then get medical attention immediately, no matter how minor the injury or contamination seems to be. Cleaning up the affected area should be done after injured persons are treated.

Even if there are no injuries, clothes and shoes must be still washed before being used again. In particular, the rubber in shoes can absorb the mercury they come in contact with (usually from the floor), so shoes must be washed thoroughly, and all contaminated items should be washed separately from non-contaminated items. Mercury on the floor will be picked-up by the shoes of others as well as the feet of pets, so keep uncontaminated individuals and all pets out of the area until it is cleaned-up.

Inhalation of any mercury vapor is extremely dangerous, and mercury vapor will be present if the lamp was operating or was hot when it was broken.
