Anthrax attack: What to do

The threat of infection from anthrax is negligible

Panic has been spreading in America after a fourth anthrax infection was confirmed following contact with suspect mail packages.

Security experts say, though, that there is little cause for alarm if people take basic precautions when dealing with suspicious packages.

Be alert

If you suspect you have received mail containing dangerous items, check the packaging thoroughly before opening.

Take special care with packages

from senders you do not know

that have mis-spelled words

that have protruding wires

that are lopsided or uneven

that have a strange odour, discolourations, oily stains or crystallisation on the wrapper

that have excessive tape or string

that are unexpected

that appear to contain powder or other unusual contents.

At home

If any of the above appear to apply, do not panic. If it happens at home, ring the police and follow their instructions.

Advise your employees of any suspicious packages as soon as possible

If you come across a suspect package at work, put it into your bin and place something on top of it, or put it in a plastic bag which can be sealed.

Put a clear sign on the suspect package signifying it shouldn't be touched, then telephone the emergency number for your building, explaining who and where you are, how you can be reached by telephone and why you are suspicious.

You may be asked where the item has come from and to whom it is addressed.

Stay calm

If you have already opened the mail or package and you're worried by the contents, remain calm, and ensure that no one enters or leaves the room.

This is a precaution to limit those who might be exposed to any risk and to enable your employers to take quick action if appropriate.

This advice applies equally in large, open-plan offices.

Providing action is taken in the above fashion the risk from inadvertently opening a contaminated package is negligible, and any subsequent health effects are very likely to be treatable with antibiotics.
