Department Specific Safety Procedure Guidelines & Training

Miami University's Chemical Hygiene Plan

The CHP establishes guidelines for the handling and storage of chemicals, for procedures that involve heavy and/or sensitive equipment, and for general work practices in laboratories where chemicals are used or stored. The CHP was developed under the Occupational Safety and Health Administrations (OSHA) Lab Standard. Development of Miami’s CHP was also informed by Ohio state law and generally accepted industry standards.

Identified Safety Hazards in the Bioengineering Laboratory

There several specific safety hazards in the Bioengineering Laboratory of which you should be aware.  Examples of these hazards are identified below, and basic safety rules for dealing with them are described.

Chemical and Hazardous Waste

  • The Bioengineering Laboratory contains numerous solvents, salts, acids, bases, oxidizers, and other hazardous chemicals.  For specific chemicals you should consult the MSDS for proper disposal methods.  Many chemicals must be disposed of as hazardous waste.  Proper procedures for generating, labeling, and disposing of hazardous waste should be followed.  Additional information on hazardous waste disposal can be found at:  
  • It is important that non-compatible wastes not be mixed when storing them or preparing them for hazardous waste disposal.  A chemical compatibility chart is located in the laboratory for commonly used chemicals in order to keep non-compatible chemical wastes separate.  
  • Chemicals in the laboratory may present other health risks (carcinogen, reproductive toxins, etc.) and proper PPE should be work at all times.  The MSDS should also be consulted before working with any chemical.
  • When a new or replacement chemical arrives in the lab, it should be marked with the user (or PI) name and the date on which it was received.


  • There are several sources sharps in the Bioengineering Laboratory. These include needles, razor blades, and microtome blades for the cryostat.
  • Sharps that are not contaminated as biohazard should be placed in a properly marked, hard container.
  • Biohazardous sharps should be disposed of in a solid, red Biohazard sharps container.
  • The cryostat is a sharps hazard.  It contains a sharp, mounted blade.  When not in use, the cryostat should be in the locked position.  The cryostat should not be touched or used if you have not been trained.



  • The Bioengineering Lab may contain biohazard: agents that may cause human disease.  These include infectious bacterial strains and human cells.  These should be disposed of in properly labeled biohazard containers.
  • Non-biohazardous biological agents (e.g., mammalian cells or mammalian cell lines not infected by agents of human origins) can and should be disposed of as regular waste.


Splash and spill hazards

  • Disposal of chemical or biological agents (when permitted) down the sink represents a splash hazard.  In particular, many biological agents will be bleached before sinking.   Additional care should be taken to use laboratory goggles when disposing of items down laboratory sinks.
  • In the event of a small spill (< 300 mL) the spill can cleaned with an appropriate spill kit.  Several kits are available in the lab for cleaning solvents, acids, and bases.  Bleach and absorbent pads are also available to clean biological agent spills.
  • For larger spills, contact Environmental Health and Safety at x-92829.  If the spill is an emergency and/or presents a danger to laboratory (or building) personnel, then evacuate the laboratory (or building if necessary) and call 911.


Compressed Gas

  • There are several canisters of compressed gas in the Bioengineering Laboratory.  These may include carbon dioxide, nitrogen, and/or argon.  
  • Tanks should always be properly mounted and secured.  If you observe tanks that do not appear to be properly mounted and secured, contact a Bioengineering Laboratory faculty.
  • Do not move compressed gas cylinders without permission and proper training
  • Do not used compressed gas cylinders or the attached regulators without proper training


Cold hazards

  • The bioengineering lab has several cold hazards including a -80oC freezer, freeze drier system, and liquid nitrogen storage units.
  • Do not enter the -80oC freezer without laboratory gloves.  Additional cold gloves may also be worn.
  • Liquid nitrogen is a significant burn hazard in the lab.  Do not use liquid nitrogen without proper training.  When pouring, additional PPE must be worn including a face shield and special cold gloves.

Mechanical hazards

  • The Bose and Instron mechanical testers represent mechanical hazards in the laboratory.  Improper use can lead to crush or other injuries.  These pieces of equipment should not be used without proper training.
