In the wake of the In Amenas gas plant terror attack in Algeria this year the Foreign Secretary said the FCO had consulted businesses in high-risk regions and the families of those affected.
Mr Hague said more advice could help companies make better decisions on keeping their employees safe and to make longer term decisions on investments.
The FCO will therefore "engage" businesses who employ Britons in high-risk locations, offer British businesses and organisations the opportunity to apply to take part in "crisis table top exercises" and include more "contextual information" on the FCO's travel advice pages.
In a written ministerial statement, Mr Hague said: "The attack in January this year on a gas production facility in the Algerian desert by a terrorist group linked to al Qaida underlined the threat British businesses and nationals can face overseas. Five out of the thirty eight people killed were British nationals and one was a British resident.
"Since the attack we have consulted many British extractive industries that operate in high-risk environments and spoken to families of those affected by this tragedy. Many have said they would like to gain a better understanding from government of the terrorism fuelling the threats we describe in the FCO's Travel Advice.
"Companies have said the additional information could allow them to make better decisions on securing their employees, and also to make longer term decisions on what can be significant investments. And we have stressed to industry how important it is to ensure the availability of information to all those employed at any site, including subcontractors."
