Carbon Monoxide

Generators are considered stationary combustion engine devices. 

They emit carbon monoxide when operating, which is dangerous and can be fatal.  There are regulations, article 37 of the National Fire Protection Agency being one, which help protect the consumer when they are followed.

Carbon monoxide detectors are a good idea when gaseous appliances or devices such as generators, gas logs, gas hot water heaters, or gas furnaces are being used at your location.

Ventilation

Adequate ventilation for your generator set is an important consideration and should not be overlooked. 

All generator product has been engineered for certain clearance requirements for engine cooling.  Typically if the same 60" requirement of NFPA 37 is met, by default clearance for proper ventilation would be afforded the generator set.

Inadequate ventilation will lead to generator set failure and damage. 

High ambient temperatures combined with inadequate ventilation will cause oil vaporization which could lead to failure of the equipment.

Additionally there are working clearance requirements for all electrical or mechanical equipment.  The space in front of and around equipment provides for a safe work environment for service personnel  and adequate space for practical service and or repair.

Generator Placement

The placement of the generator should get special attention.

Once the location has been decided upon, taking into consideration clearances, direct sunlight areas, adjacent origins of condensation, access, and others, then preparation of the area must be completed.  A good solid foundation is required and grade should be worked so that water passes by the generator concrete pad or base.  Erosion under or around the generator base can create an out of level condition which could prove to be bad for components of the generator.  Additionally  water and sludge build up around the base of a generator will cause corrosion problems which can become expensive. 

Rock should be placed around the generator bases and combustibles kept away.

Sometimes considerations have to be made for flood zones and the possibility of water rising above the pads for generators at ground level.  It is possible to raise the generators on wooden or concrete structures but caution should be used when utilizing any combustible type materials.  Solid construction is very important and making sure the base of the generator is kept closed will keep overheating issues at bay.
