Stationary Process Container Labeling

Stationary process containers are... well... stationary! Large storage tanks are good examples.

Employers may use signs, placards, process sheets, batch tickets, operating procedures, or other written materials in lieu of affixing labels to individual stationary process containers.

  • The alternative methods must identify the containers to which they are applicable and convey the information required on workplace containers.
  • The written materials must be readily accessible to the employees in their work area throughout each work shift.

Portable Container Labeling

Portable containers are used to transfer hazardous chemicals from labeled containers, and are intended only for the immediate use of the employee who performs the transfer.

The employer is not required to label portable containers. Drugs which are dispensed by a pharmacy to a health care provider for direct administration to a patient are exempted from labeling.

Figure This Out

It's important to know that portable containers must be under the positive control of the employee using it. Let's say an employee is cleaning some parts with solvent he has placed in a plastic container. If he is using it for immediate use and can prevent another employee from exposure, labeling is not required. But what must he do if he walks away from the workstation to go on a break (or for any reason), losing control of the chemical?

Since he loses positive control of the container, it must be labeled as a workplace container. OSHA inspectors routinely find containers in workplaces that are not properly labeled. As a safety person, ensure you're always on the hunt for unlabeled workplace containers!
