Questions contractors ask

Short answers before you act.

Does OSHA have one shipping-container rule?

No single rule covers every use. Applicable requirements come from material storage, egress, fire, electrical, hazardous materials and the actual work being performed.

Can workers use the container as a break room?

Only when the unit is purpose-designed and approved for occupancy. Egress must remain unobstructed and must not permit workers to be locked inside; ventilation, electrical, fire and local-code requirements may also apply.
