Chemical Hygiene Plan


Lycoming College has developed this Chemical Hygiene Plan (CHP) in compliance with the Occupational Safety and Health Administration (OSHA) Laboratory Standard Rules and Regulations. This Laboratory Standard is published as an amendment to 29 CFR 1910, Subpart Z, and identified as Section 1910. 1450. The title of that amendment is Occupational Exposure to Hazardous Chemicals in Laboratories. The Laboratory Standard applies only to laboratories meeting the four criteria given under the designation of "laboratory use of hazardous chemicals" in the definitions of the Standard. OSHA defines a hazardous chemical as a substance for which there is statistically significant evidence, based on at least one scientific study, showing acute or chronic harm may result from exposure to that chemical.

This is the Chemical Hygiene Plan developed for laboratories at Lycoming College in Williamsport, Pennsylvania. This CHP is maintained readily available to laboratory employees in the Reading Rooms of the Chemistry and Biology Departments in the Heim Building, as well as in the Safety and Security Office in the lower level of Rich Hall. It will also be available on-line on the Home Pages of the Chemistry and Biology Departments (http://www. lycoming. edu/dept). All laboratory personnel must know and follow the procedures outlined in this plan. All operations performed in the laboratory must be planned and executed in accordance with these procedures. In addition, each employee is expected to develop safe personal chemical hygiene habits aimed at the reduction of chemical exposures to themselves and coworkers.

The two critical features of the Laboratory Standard are the requirement to appoint a Chemical Hygiene Officer (CHO), and the requirement to develop and implement a Chemical Hygiene Plan (CHP). The CHP reflects the particular character and operations of the individual laboratory situation, and may be subject to revision as required by changing conditions or circumstances.

Each department which has laboratories meeting the four criteria established in the Laboratory Standard shall designate a departmental Chemical Hygiene Officer (CHO). The CHO acts as the representative of the President of the College who has the ultimate responsibility for chemical safety in that department. The CHO also reports to the Director of Safety and Security or the Safety Officer as that person designated by the President and Dean of Student Affairs for overseeing any financial implications of the CHP and chemical safety. The CHP will be distributed to all fulltime employees of the laboratories designated above and copies will be accessible to any other laboratory employees, student laboratory assistants, or other interested parties. The CHP will be reviewed at least annually and updated if necessary.

This CHP, which is applicable only to laboratories, is one component of the Lycoming College Life Safety Plan (LSP). While the LSP applies to all departments, laboratories in compliance with this CHP are not required to comply with the Hazard Communication component of the LSP. At a minimum, this CHP covers employees (including student employees, technicians, researchers and faculty) who use chemicals in teaching and research laboratories at Lycoming College. Certain non-traditional laboratory settings may be included under this CHP at the option of the individual departments within the College. Also, it is the policy of Lycoming College that laboratory students, while not legally covered by the Laboratory Standard, will be given training commensurate with the level of hazard associated with their laboratory work. Finally, individual supervisors are encouraged to implement additional chemical hygiene provisions for their laboratories as appropriate.


Section and Title Page


1. Standard Operating Procedure for the Chemical Laboratory

2. Criteria for Implementation of Control Measures
In this section the criteria are presented by which the use of engineered controls and/or personal protective equipment are to be used.

3. Engineering Controls
4. Employee Information and Training
5. Prior Approval for Laboratory Activities
Certain laboratory activities present specific, foreseeable hazards. These activities include off-hours work, sole occupancy of building, hazardous operations and unattended operations. Written prior approval must be obtained from the supervisor prior to the performance of these activities.

6. Chemical Hygiene Responsibilities
7. Special Precautions
When laboratory procedures require the use of additional classifications of chemicals (defined in the appropriate MSDS as allergens, embryotoxins, teratogens, carcinogens, etc. ), additional special precautions shall be implemented as deemed necessary by the Chemical Hygiene Officer.
In general for each of these categories it is expected that the hazardous chemicals will only be used where necessary (i. e. , no safer, equally suitable alternative exists) and that the amounts used will be the minmum required.

8. Chemical Spills, Releases and Accidents
In the event of a chemical spill, release or other accident, all employees will adhere to the procedures outlined in the Emergency Response plan as required by OSHA standard 29 CFR 1910. 38 and 1910. 120.

9. Medical Consultations and Examinations
10. Laboratory Waste Disposal
The accumulation of waste in these departments is of such a small quantity as to put the College well below the level of a small quantity waste generator classification; nevertheless, it is expected that extra care will be exercised to ensure the proper collection and disposition of any hazardous waste.
Disposal of all chemical waste will be carried out under the direction and/or supervision of the Chemical Hygiene Officer in conjunction with the Safety Officer. Each Department and Laboratory Supervisor shall ensure proper collection (for disposal) of wastes generated in their laboratories. Solid chemical wastes should not be discarded into waste baskets, but rather disposed of in a permissible way. Any accidental mercury spills (for example, from broken thermometers) will immediately be cleaned up with a vacuum collector, by a faculty member.
11. Recordkeeping

12. Annual Chemical Hygiene Plan Audit
The Chemical Hygiene Officer will conduct an audit of all phases of the Chemical Hygiene Plan each year. Results will be provided to the ranking official and the laboratory manager. Supervisors are responsible for taking corrective action. Appendix D will be used as a guide for the audit.

C) Database Functions

  • Special Functions / Buttons: In addition to the information present on the Main Form for each chemical and the Container Subform for each container, there are several functions built into the database represented by the following buttons.

  • Find Chemical: This will search for any string of characters, and currently looks in every field of the main form. There are three possibilities for searching in the pull down list, given after "Where": Any Part of Field, Match Whole Field, and Start of Field. In these searches, case is ignored, Start of Field is usually the fastest, and Any Part of Field is the slowest. It is not a bad strategy to search only on those parts of the name you are reasonably sure of (e.g. search for"copper sulfate" with Start of Field if not sure about hydrate) or even better, to search on CAS number. The (search) Direction up is Z to A, while down is A to Z. Find First starts from the first record and searches, while Find Next starts from the current record. Thus if you were at the record for "Nickel", it would be better to search for "Sodium Chloride" using Find Next, but better to search for "Magnesium" using Find First. Close gets you out of the search once the item sought is found.

  • Add New Chemical: Adds a new, blank record after the current last record. Please fill in as much of the information asked for as possible. In the Main Form, Sort Name is required. In the Container Subform, Room, Amount, Rec'd, and Chem/Bio are required. The nonnetworked version of the database will not sort this new record into proper alphabetical order when it is done.

  • Record: This bar is found below both the Main Form and the Container Subform. In either form the buttons function the same. The "|<" button will take you to the first record, "<" takes you back one record, ">" takes you forward one record, and ">|" takes to the current last nonempty record. Between these buttons is the text "Record X of Y". Y is always the total number of records (chemicals for the Main Form, Containers for the Subform). Typing in a new number X takes you to that number record (and is the fastest way to get to a particular place in the database, if you know the record number). Once the inventory of existing chemicals is complete, an alphabetical list of record numbers will be distributed (so you can go to record 1235 to start all the "sodium" records, and then go forward with ">" to "sodium sulfate").

  • Exit: This saves all changes made so far and leaves the program altogether.
