4. Summary. Particular attention should be paid to operations involving exposures to carbon monoxide during the
winter months, when windows and doors in buildings are generally closed and carbon monoxide concentrations may
reach dangerously high levels. Where rates of generation of combustion products exceed the capacity of natural
ventilation to maintain a sufficiently low atmospheric concentration of carbon monoxide, supplementary mechanical
controls may be necessary.
