Failure of the settlement
A complete failure of the colony would mean the death of all settlers. Possible causes can be human failure, technical failure and acts of nature beyond control. It could take decades or centuries before a subsequent colonization attempt is started. This article wants to collect situations, incidents, precautions and mitigations.

Destruction of life support
Precaution: Underground parts of the settlement draw benefit from the high heat capacity of the surrounding rock, which keeps the temperature for a long time. The interior of the settlement rooms can be optimized to store large amounts of warmth. Big water tanks have a high heat capacity.
... with radioactive, chemical or bacteriological substances
Precaution: If dangerous substances are not produced, they can not pose a threat. If such substances are unavoidable, they should be produced, used and stored in a separated part of the colony, where no other vital system can be affected in case of an incident.

Destruction of equipment that is needed for maintenance of vital systems
The human metabolism need a great variety of substances. The full complexity of all interactions is not fully understood. If there is a shortage or an excess of some rather unknown substances, the health might be seriously affected. In worst case the ability to work and maintain the vital parts of the colony falls below a required minimum. Such substances may possibly produced by some sort of germs that are omnipresent on Earth, but are not in the Martian colony.
The immune system may get out of balance, since the ensemble of germs around and inside of the settlers will be different or narrowed. If, unlike in the ISS, the bacteriological profile is not updated frequently, some vital germs might become extinct.
Mitigation: A garden with soil is a living ground for many microbes and germs.
