There are numerous documents that define the term "adequate ventilation", but ANSI Z129.1 (1976) defines it as

“a condition falling within either of the following categories:
1) Ventilation to reduce levels of air contaminant below that which causes personal injury or illness
2) Ventilation sufficient to prevent accumulation of significant quantities of vapor-air mixtures in concentration over one-fourth of the lower flammable limit.”

OSHA’s definition says that “ventilation required (natural or mechanical) such that personal  exposure to hazardous concentrations of airborne contaminants are maintained below the allowable levels or sufficient to prevent accumulation of significant quantities of vapor-air mixtures in concentration over one-fourth of the lower flammable limit.”
