highly hazardous materials. (See Chapter 4, section 4.D.)

   Inspect and test peroxide-forming chemicals periodically (these should be labeled with an acquisition or expiration date), and dispose of chemicals that have exceeded their safe storage lifetime.

   Store particularly sensitive materials or larger amounts of explosive materials in explosion relief boxes.

   Restrict access to the storage facility.

   Assign responsibility for the storage facility and the above responsibilities to one primary person and a backup person. Review this responsibility at least yearly.

5.E.8 Storing Highly Toxic Substances

Take the following precautions when storing carcinogens, reproductive toxins, and chemicals with a high degree of acute toxicity:

   Store chemicals known to be highly toxic in ventilated storage in unbreakable, chemically resistant secondary containment.

   Keep quantities at a minimum working level.

   Label storage areas with appropriate warning signs, such as




   Limit access to storage areas.

   Maintain an inventory of all highly toxic chemicals. Keep records of acquisition, use, possession, and disposal. Some localities require that inventories be maintained of all hazardous chemicals in laboratories.

Note: Facilities covered by the OSHA Laboratory Standard must use and store carcinogens, reproductive toxins, and chemicals with a high degree of acute toxicity in designated areas.


U.S. and international regulations apply to the movement of chemicals, samples, and other research materials on public roads, by airplane, or by mail or other carrier. When moving these materials on-site, anyone personally transporting regulated materials between adjacent or neighboring buildings within an institution should walk. (Secondary containment, such as a rubber bucket, should always be used for carrying bottled chemicals.) Organizations located in a larger campus setting should have guidelines indicating if special courier or designated vehicles are to be used to transport regulated materials according to applicable regulations.

Samples of experimental material to be transferred outside the laboratory, or that may be handled by individuals not generally familiar with the type of material involved, should be labeled as completely as possible. In addition, hazardous samples sent to individuals at another institution must be accompanied by appropriate labeling and an MSDS, according to OSHA’s Hazard Communication Standard amendments and OSHA’s Laboratory Standard hazard identification provision, including the name, address, and contact information of the sender and recipient for samples in transit. When available, the following information should accompany experimental materials:

   Originator: List the name of the owner or individual who first obtained the material. If sending the material to another facility, add contact information for the person who can provide safe handling information.

   Identification: Include, at least, the laboratory notebook reference.

   Hazardous components: List primary components that are known to be hazardous.

   Potential hazards: Indicate all known or potential hazards.

   Date: Note the date that the material was placed in the container and labeled.

   Ship to: Indicate the name, location, and telephone number of the person to whom the material is being transferred.

When transporting or shipping most chemicals, biological agents, and radioactive materials, even small amounts or samples preserved in solvents or alcohol, domestically or internationally, please note that the DOT or the International Air Transport Association (IATA) regulations may apply. Before preparing any packages for shipment, personnel must have documented evidence that they have complete DOT and IATA training. DOT controls shipment of chemicals by a specific set of hazardous materials regulations, 49 CFR Parts 100-199 (updated 2006). These regulations contain detailed instructions on how to identify, package, mark, label, document, and placard hazardous materials. Shipments not in compliance with the applicable regulations may not be offered or accepted for transportation. The regulations on training for safe transportation of hazardous materials are located in
