inspector reasonably determines conditions or materials
are hazardous to health or safety of the inspector.
OSHA also has many other requirements as they consider a crawl space to be a confined or enclosed space. Their standards indicate level of O2
("oxygen-deficient atmosphere" means an atmosphere having an oxygen concentration of less than 19.5 percent by volume.)
