Lab Inspection Criteria

General 1 and 2 – Door signs

Laboratories are required to have personnel contact numbers on the outside of their laboratory door, in the event of after-hours emergencies.  Two (or more) names should be listed, in case one person is not available.

In addition, if the lab contains physical or health hazards that emergency personnel should be aware of, these hazards should also be indicated on the external lab door.

To request a new or updated door sign, follow this link: Laboratory Door Sign

Specific citations:

1. Emergency contact numbers (two names, preferably the PI, head technician, or a graduate student) shall be posted on the external doorway to the lab. These names and numbers shall be updated when personnel change.  (Chemical Hygiene Plan:

2. If a laboratory has 10 gallons or more of a flammable or corrosive liquid or toxic gas(es), the main doorway to the lab shall have a hazard warning sticker visibly posted on it to indicate the potential hazard.(Chemical Hygiene Plan:

General 3 and 4 – (M)SDS signs and access

The Michigan Occupational Health and Safety Administration requires every workplace to post information about the location of Material Safety Data Sheets or Safety Data Sheets for the chemicals used in the laboratory.

For an updated MIOSHA (M)SDS poster, follow this link: (M)SDS Poster (PDF)

In addition, employees must understand how to access the (M)SDSs for their location.  Laboratories have two options:

  • Keep (M)SDSs for their location either in paper form or electronically in their laboratory. Employees must demonstrate they have been trained on where these (M)SDSs are kept in the laboratory
  • MSU EHS has an online (M)SDS repository of thousands of (M)SDSs; the State of Michigan has indicated that this can serve as the (M)SDS location for all laboratories on campus. Employees must demonstrate they are aware of the online (M)SDS repository, and know how to access it when asked.  The link to the MSU EHS online (M)SDS database is here: (M)SDS Database

Specific citations:

1. Every laboratory shall have the Michigan Right-to-Know Law poster visibly posted, listing the location of MSDSs for all hazardous chemicals used in the lab. (Chemical Hygiene Plan

2. The system a unit uses to store MSDSs can vary from keeping them in a filing cabinet to using the EHS request system. Each unit must post a Michigan Right-To-Know Law poster, which indicates the location of all MSDSs for hazardous chemicals used in the lab. (Chemical Hygiene Plan 5.1.1)

3. Employers shall organize the safety data sheets for the hazardous chemicals in the workplace in a systematic and consistent manner and shall train employees in locating particular safety data sheets.

(OSHA 1910.1200 (g))

General 5 and 6 – Safety Training

All laboratory employees are required to be trained on the hazards of their workplace.  This training is to take place

  • At the time of initial assignment, and
  • If the scope of work changes sufficiently to warrant retraining, and/or
  • Annually, if determined necessary by the employer

This safety training has two parts – general online training modules and site specific training modules

The online training modules can be found here: Online Training Modules

You and your employees will be notified via email if any of your online training modules are overdue

Site-specific training modules are to be performed regularly for each employee.  Site-specific training needs to be documented, and specific for the laboratory operations.  The goal of site-specific training is to give the PI an opportunity to discuss in detail safety procedures specific to their lab operation with every employee.

A sample site-specific training template is located here: Site Specific Training Template (PDF)

Documentation of both online modules and site-specific training records should be available to inspectors.  These can be paper or electronic copies of training records.

Specific citations:

5. Site-specific training must be documented and maintained by the unit/PI/supervisor and be available to representatives of the EHS, the CHO, members of the CHS or other regulatory officials upon request. (Chemical Hygiene Plan: 1.9)

6. All laboratory employees who handle hazardous chemicals shall attend the Chemical Hygiene & Laboratory Safety course offered online at This training shall be at the time of initial assignment and prior to handling any hazardous chemicals. Employees should receive periodic refresher information and training to ensure that they are aware of the risks of exposure to hazardous chemicals.   (Chemical Hygiene Plan: 1.9)

General 7-9a.  Personal Protective Equipment

Supervisors must evaluate the need for Personal Protective Equipment (PPE) for all potentially hazardous procedures performed in the lab.  The employer also needs to provide PPE for all employees; the PPE must be maintained in good working order and fit the employee appropriately.

Employees are responsible for wearing the PPE provided. 

Both employers and employees must inspect PPE on a regular basis, and discard or repair those items that are broken, damaged or no longer offer protection. 

Examples of Personal Protective Equipment include:

  • Chemical protective gloves appropriate for chemicals used, free of rips or cracks
  • Reusable gloves without tears or holes
  • Safety glasses or goggles with clear, clean lenses and tight-fitting straps
  • Lab coats that are reasonably clean, free from holes, and offer appropriate protection for the chemicals being used
  • Other lab-specific PPE such as face shields, aprons or UV glasses are worn and maintained in good condition.

Labs may share a spill kit, if the spill kit can be accessed by all employees whenever someone is working in the lab.

A chemical spill kit can be purchased for $10 from The Biochemistry Store: BMB Store Catalog

Specific Citations:

14. Ready access to a chemical spill kit is required in laboratories that work with hazardous chemicals. Each laboratory’s spill kit should be kept in a readily accessible location and each employee should be trained on how to use the spill kit. (Chemical Hygiene Plan: 4.1.4)

General 15 – Broken Glass Bucket

Laboratories that use glassware need to have a broken glass bucket or box that is separate from regular trash or hazardous waste.  Broken glass that is not contaminated with chemical or biological agents is placed in the broken glass bucket for disposal.  Do not put glass or sharps of any kind in the common trash – injuries to lab members and custodial staff can occur.

Contaminated, solid hazardous waste disposal directions can be found here: MSU Waste Disposal Guide (PDF) 

Specific Citation:

15. No broken glass bucket observed. A separate waste receptacle must be designated for non-contaminated glass. Follow guidelines established in the MSU Hazardous Waste Disposal Guide for disposal of contaminated glass. (Chemical Hygiene Plan 2.4(c))

General 16 – Fume Hood Testing and Maintenance

Proper fume hood maintenance is essential to those labs working with hazardous chemicals.  Use of an untested or condemned fume hood is strictly forbidden at MSU.  Fume hoods must be kept clean, free of debris and unobstructed.

Fume hoods are tested annually by MSU EHS.  If a fume hood does not pass inspection, the room users will be notified and work in the hood must cease until the fume hood is repaired.

Supervisors should schedule maintenance and repair of fume hoods via Infrastructure Planning and Facilities.

Specific Citation:

16. MSU EHS staff will conduct fume hood testing as soon as possible.

19. An extinguisher shall have a tag attached to it showing the maintenance or recharge date and the initials or signature of the person who performed the service. (MIOSHA part 8 R408.10835(2))

General 20 – Inventory of Chemicals

An up-to-date, accurate chemical inventory is an important tool in managing laboratory chemicals.  Inspectors will ask to see a laboratory’s chemical inventory; this can be electronic or on paper.   Occasionally, entities outside of MSU will ask if certain chemical compounds are present on campus; chemical inventories make this information readily accessible.  Inventories also alert faculty and staff members if highly hazardous or toxic chemicals are misplaced in the laboratory.

Specific Citation:

20. It is recommended that each facility keep a detailed inventory of highly toxic chemicals and explosive/reactive materials. There should be a record of the date of receipt, amount, location and responsible individual for all acquisitions, syntheses and disposal of these chemicals.  A physical inventory should be performed annually to verify active records.  There should be a procedure in place to report security breaches, inventory discrepancies, losses, diversions or suspected thefts. (MIOSHA R325.70101 - R 325.70114, Appendix A: E.3). 

General 21 – Chemical Hygiene Plan

All MSU employees working with hazardous chemicals must know how to access the MSU Chemical Hygiene Plan.  The Chemical Hygiene Plan can be present in paper form, electronically, or as an active link on a computer.  Inspectors will ask lab personnel if they know where their copy of the MSU Chemical Hygiene Plan is located, and ask them to demonstrate their knowledge at the time of inspection.  The Chemical Hygiene Plan is updated on a regular basis; employers must ensure their employees have access to the latest version of the document.

The MSU Chemical Hygiene Plan can be found here:  MSU Chemical Hygiene Plan (PDF)

Specific Citations:

21. The MSU Chemical Hygiene Plan must be readily available to employees and employee representatives through their PI, supervisor, or departmental office. Additional copies of this document are available from the EHS office and the EHS website: under “Manuals and Forms.” (Chemical Hygiene Plan: 1.7)

General 22 – Laboratory Standard Operating Procedures

Employers and employees must work together to develop safe and effective work procedures, and document those procedures via a standard operating procedure (SOP).  While recommended for all laboratory operations, it is particularly important for highly hazardous chemicals, operations or dangerous equipment.  Inspectors will ask to see SOPs for items such as toxic gases, highly toxic compounds, potentially dangerous equipment, highly reactive chemicals, etc. 

The use of perchloric acid is strictly controlled at MSU.  Heated perchloric acid can create potentially explosive perchlorate salts that deposit on equipment and ventilation elements.  All laboratories using or storing perchloric acid will be required to follow all of the requirements outlined in the following document:  Safe Use of Perchloric Acid.

All users of hydrofluoric acid must also follow MSU guidelines when using and storing this compound.  This includes having a readily accessible and well-stocked HF exposure kit on hand at all times.

Other examples of SOP templates can be found here:  Toxic Gases (DOCX)  Osmium Tetroxide (DOCX)   Blank SOP (DOCX)

Guidelines for creating SOPs can be found here: Standard Operating Procedures

Specific Citations:

22. Where the scope of hazards is not adequately addressed by the Chemical Hygiene Plan, units and/or PIs must develop written standard operating procedures for work area specific operations. It is required that records of specific laboratory training for individual laboratories be retained by the PI in the laboratory or the department. (Chemical Hygiene Plan 1.10, 2.0)

Chemical 1 – Compressed Gas Cylinders

Compressed gas cylinders are to be secured at all times.  Active cylinders with regulators attached must be individually secured.  Laboratories are allowed one “stand-by” cylinder per “active” cylinder in use– excessive storage of cylinders in a laboratory is discouraged.  Place valve caps on cylinders not in active use.

Toxic, pyrophoric or corrosive gases must be used and stored in a gas cabinet or a fume hood. An SOP is required for toxic, pyrophoric and corrosive gases. See a list of these gases here: Gases Requiring Approval (XLSX)

Contact Genevieve Cottrell at 432-8715 or for gases requiring approval.

Cylinders with obvious corrosion and/or cylinders greater than 10 years old should be returned to the gas supplier immediately. Return gas cylinders by using this guide: Returning Compressed Gas Cylinders (PDF)

Flammable and oxidizing gases must be separated by at least 20 feet, per fire code.

All use areas and indoor storage areas shall be designed, constructed, maintained, and operated to prevent the release of polluting materials through sewers, drains, or otherwise directly or indirectly into any public sewer system or to the surface or groundwaters of this state. (Department of Environmental Quality: Part 5, R324.2005(3))

2. For containers labeled by the manufacturer, inspect the labeling on incoming containers. Replace damaged or semi-attached labels. (Chemical Hygiene Plan  

Chemical 3 – Proper Labeling of Chemicals

MIOSHA Hazard Communication Standard requires employers to ensure all secondary containers of hazardous chemicals are labeled with the full chemical name, and any hazards associated with the chemical.  Groups of vials, small bottles or samples can be labeled as a group with a common ticket for all items.  If the lab members wish to use abbreviations instead of full chemical name, provide an abbreviation chart in plain view in the lab.

Examples of labeling techniques can be found here: Proper Labeling of Hazardous Chemicals (PDF)

Request hazard warning labels here: Request Hazard Warning Labels

Specific Citations:

For transferred products or prepared solutions labeled by the user, label each chemical container with the chemical name and hazard warning. Refer to the MSDS for hazard warning. Hazard labels are available from EHS. (Chemical Hygiene Plan

No key observed in laboratory for abbreviations used on secondary containers. Provide a key in a visible location in the lab with complete chemical name. (Chemical Hygiene Plan

Chemical 4 – Chemical Compatibility

To prevent unintended reactions between incompatible compounds, chemical containers need to be segregated into compatible groups when in storage.  The use of secondary containment (such as bus tubs, buckets, etc.) under containers is encouraged. 

For further information on chemical compatibility, follow this link: Chemical Compatibility Information (PDF)

Specific Citation:

4. Classes of incompatible chemicals should be segregated from each other during storage, according to hazard class. Please refer to Appendix B of the MSU Chemical Hygiene Plan for further assistance. (Chemical Hygiene Plan: Appendix B)

Chemical 5 & 6 – Peroxide-Forming Reagent Management

Certain classes of compounds will form potentially explosive peroxide crystals upon extended storage.  Common examples of peroxide-forming compounds include: isopropyl ether, diethyl ether, tetrahydrofuran, dioxane, potassium metal. 

These compounds must be used in a timely manner, or tested on a regular basis to ensure peroxide formation is not occurring.  A label affixed to the outside of the container should indicate date of last test, and test results.  Any compound testing positive for peroxide formation must be disposed of via MSU EHS.

Peroxide forming compounds that are very old, have obvious container problems, or show visible crystallization inside the bottle or cap require immediate, specialized management.  Telephone MSU EHS directly at 517-355-0153 for immediate assistance.  Leave the container in place until MSU EHS arrives.
