Unless you are equipped with self-contained breathing apparatus (SCBA), you should avoid using fire extinguishers that displace the breathable oxygen, generate other asphyxiants or otherwise implicate your ability to breathe.
If you do not have SCBA and vapor-barrier protection (e.g., structural or aircraft firefighter turnout suit) and you should avoid using water-based extinguishers that can turn into 20,000 times more steam.

A carbon dioxide extinguisher (used on electrical installation fires) should not be used in a confined space, as the user could be overcome and be asphyxiated (deprived of air).
As long as the fixture in the confined space is approved for confined space and the wattage rating of the fixture is not below 60 watts then there should be no problem using a 60 watt bulb in this situation.
Confined space is an area that is enclosed. A dog kennel could be a confined space for a dog. A living room is a confined space for example.
There is currently a sale on confined space gas detectors at pksafety. They have several models to choose from: http://www.pksafety.com/confined-space-gas-detectors.html
Carbon Dioxide extinguishers displace the air from the immediate area, and so are not suitable for confined spaces (though they're safe in a normal-sized room). Dry powder is non-toxic, but is discharged as a cloud of irritating dust, which can cause vision problems in a confined space. Generally, I would use the nearest extinguisher suitable for the fire, and vacate the area immediately after discahrge to wait for the fire service to check the area.

Confined space is an area which is enclosed with limited access which makes it a dangerous place to be in. Therefore, confined space rescue refers to techniques to save people whos been trapped in confined spaces.
A confined space is an enclosed area that has limited access and may have a risk of hazardous conditions such as poor ventilation or the presence of toxic substances. Examples include storage tanks, sewers, and tunnels. Proper precautions and safety measures should be taken when working in confined spaces to prevent accidents or injuries.
There should be about a 1 metre (or 3 feet) clearance around any fire extinguisher. This ensures easy access in a emergency situation.
The minimum oxygen level for a confined space should be at least 19.5%. Levels below this can be unsafe for workers, potentially leading to asphyxiation and other health risks. It is important to monitor and maintain proper oxygen levels in confined spaces to ensure safety.
