Beware of Other Hazards
OSHA has found that confined spaces hazards frequently occur in parallel with other hazardous conditions.
Hazards of uncontrolled release of energy (e.g. electricity, high pressure fluids and gases, or mechanical energy) often occur in confined spaces. These hazards are addressed by the OSHA Lock-out Tag-out standard at 29 CFR 1910.147.
