Heating elements would raise ambient temperature, increasing thermal stress on electronics rather than protecting them from dust or static.

Compressed air cans are the standard tool for blowing dust and debris out of vents, fans, and circuit boards in dusty field environments, preventing overheating and component damage caused by particulate buildup.

Extra computer cases provide physical housing but offer no protection against dust infiltration or electrostatic discharge in a harsh environment.

Spare cables address connectivity redundancy but do not protect equipment from dust accumulation or ESD caused by dry conditions.

A humidifier counteracts extremely low humidity in arid environments, which dramatically increases electrostatic discharge (ESD) risk - ESD can permanently damage sensitive electronic components, so maintaining adequate moisture levels is critical protection.

Oxygen tanks are not relevant to computer equipment protection; they address air supply for personnel, not environmental hazards affecting electronics.
