Chemical Hygiene Plan

5.0 Hazard Recognition

The PI/Lab Supervisor with the assistance of the SO/CHO is responsible for the recognition of hazards related to the use, storage, and disposal of laboratory chemicals. The two most important aspects to the recognition process are ensuring that laboratory personnel have access to Material Safety Data Sheets (MSDS) and an inventory of laboratory chemicals used and stored is maintained.

5.1 Material Safety Data Sheets (MSDS)

MSDS are documents prepared by the manufacturer that contain the following information:

  • Identity of the product and manufacturer.
  • Ingredients, percentages and exposure limits, where appropriate.
  • Physical properties, fire and explosion hazards and reactivity data.
  • Health hazards.
  • Release, spill and disposal information.
  • Personal protective equipment.
  • Handling and storage procedures.

The PI/Lab Supervisor with the assistance of the SO/CHO is responsible for ensuring that MSDS are readily available.  MSDS are available online (msdsonline.com) for most laboratory chemicals used at Westmont . For those chemicals for which MSDS are not available on the Web site, MSDS must be obtained and maintained at the location where the chemicals are used.

The PI/Lab Supervisor with the assistance of the SO/CHO is responsible for providing training regarding MSDS retrieval on-line and documenting the training. The PI or SO/CHO is also responsible for ensuring MSDS are accessible in the event of power failure.

5.2 Hazardous Chemical Inventory

The PI/Lab Supervisor with the assistance of the SO/CHO is responsible for maintaining a chemical inventory which includes all chemicals acquired, used, stored or transferred in the laboratory and uploading this information to the online Chemical Hygiene Plan.

The PI shall make available, and make known the location of, reference materials on the hazards, safe handling, storage and disposal of laboratory chemicals including, but not limited to, MSDS.

5.3 Labeling of Chemicals

All chemicals are required to be labeled with the following:

  • Identity of the hazardous chemical or mixtures.
  • Hazard warning(s).
  • Name and address of the manufacturers, importer or other responsible party.

Chemical users should:

  • Ensure manufacturers' labels on new container are not removed or defaced.
  • Clearly mark on the chemical containers the dates the containers are received and opened.
  • Properly label "in-house" containers when transferring chemicals.
  • Ensure that piping systems used for chemical transport are labeled for contents and direction of flow.
  • Properly label waste containers.

5.4 Laboratory-Developed Chemicals:

Chemicals produces in the laboratory require special consideration.

  • If the composition of the chemical substance which is produced exclusively for the laboratory's own use is known, the PI, with assistance from the SO/CHO, will determine if it is hazardous.
  • If the chemical is produced as a byproduct whose composition is not known, it shall be assumed to be hazardous.
