Here are some occupational safety guidelines from a US Army manual for
preventive medicine. They clearly name diesel exhaust emissions in
cconfined spaces as a cause of death by asphyxiation.

IH Concerns in Confined Spaces

Citation: Johnson, L.F., Dangerous Atmospheres: IH Concerns in Confined
Spaces, Occ. Health & Safety, 65(5) 43-47 (1996).


All Army IHs should be involved in the installation confined space entry
programs. At a minimum our involvement should include verification that
appropriate atmospheric testing is accomplished and the PPE to include RPE
is properly used. This article concentrates on conditions that can result
in
asphyxiation, the leading cause of death in confined spaces, and proper
monitoring techniques. OSHA states the following activities can produce
oxygen-deficient atmospheres: 1) recirculation of diesel exhaust emissions;
2) solvent exposures; 3) welding operations; 4) fugitive dusts from metals
cleaning operations; 5) combustible gases and vapors; 6) decaying organic
materials; 7) simple asphyxiates; and 7) chemical asphyxiants like CO and
cyanides.

Testing of confined spaces prior to entry is essential as is continuous
monitoring of the space as long as it is occupied. Testing must be done in
the
following order: oxygen, combustible gases and vapors, and toxic gases and
vapors. The monitoring instruments must be intrinsically safe, portable,
reliable, accurate, and easy to use. Most importantly, the equipment
operators must be properly trained in the use of the equipment and the
equipment
must be properly selected for the monitoring task. Involvement by Army IHs
can ensure proper surveillance of confined spaces and could result in
saving lives.

I do not have access to the book by L. F. Johnson, but it appears evident
that diesel exhaust emissions can result in oxygen-deficient atmospheres
with consequent asphyxiation in enclosed spaces.
