Chemical Storage

Signs and Postings

Ensure that storage areas are properly posted as to their contents and any warnings that may be necessary.

Is this a suitable hazardous chemical container?

Department of Transportation (DOT) markings may be required on buildings housing chemicals during rig moves or building transport. Cabinets and storage bins used for chemical storage must be labeled. Outside storage areas containing hazardous chemicals must have signs and be clearly defined.

Containers and Marking

The law requires that chemicals, regardless of the container they are stored in, must be clearly marked as to contents and health hazards. A system for marking and communicating chemical information should be part of the rig’s safety program. Ensure that chemical storage on the rig complies with company rules.

Chemicals must never be stored or transported in water bottles, cups, or cans that have contained or could contain fluids for human consumption.

Spill Reporting and Clean Up

Chemical spills can be a serious environmental exposure. Local, State, and Federal laws may apply to spills of highly hazardous chemicals. Ensure that any release of hazardous chemicals is reported to your supervisor. Always follow clean up and disposal instructions included in the appropriate SDS.
