This document advertises an 8-hour online confined space training course that is OSHA accepted. It notes that 100-300 workers are killed each year in confined space accidents, representing a small percentage of overall workplace fatalities but a high rate given the number of workers involved. The dangers of confined spaces include atmospheric and other hazards that may not be apparent and can be difficult to avoid or escape from. The majority of confined space fatalities involve atmospheric hazards like low oxygen or toxic gases. Training and proper safety procedures are emphasized as the overwhelming majority of confined space deaths involve untrained workers.
