The Laboratory Safety and Chemical Hygiene Plan (CHP) is a written program for ensuring the safe use of chemicals in laboratories at Indiana University. It describes policies, procedures, and control measures that must be understood and observed by all individuals involved in the laboratory use of chemicals.
Laboratory Safety and Chemical Hygiene Plan
There are eight main sections to the IU Chemical Hygiene Plan. Click the link below or use the buttons to navigate to a specific section of the Laboratory Safety and Chemical Hygiene Plan.

- Major emergencies
In the event of an accident in the laboratory which involves a fire, explosion, or a large release of a hazardous chemical:
- Evacuate the building by activating the nearest fire alarm.
- Call 911 to give the details of the accident including the location, personal injuries, and types of hazardous material involved.
If the accident also involves chemical contamination or serious personal injury (e.g. profuse bleeding, broken bone, unconsciousness, immobile victim, etc.) follow the steps above and:
- Move the victim from the immediate area of the fire, explosion, or spill (but only if this can be done without further injury to the victim or to you).
- Remove any contaminated clothing from the victim and flush all areas of the body contacted by chemicals with copious amounts of water for 15 minutes.
- Administer first aid as appropriate and wait for emergency medical responders to arrive.
- Minor emergencies
If the accident involves minor injuries requiring treatment, report to the medical services provider for your respective campus (See Medical Consulatation and Examinations):
- Administer first aid as appropriate and report to the appropriate supervisor or to the administrative office in the building or department as necessary.
- Responsible departmental personnel such as faculty, staff, or building managers should coordinate transportation assistance for the injured person upon request.
- Use departmental vehicles whenever possible or voluntary use of personal vehicles if necessary.
- Drivers must have a valid driver’s license and observe local speed limits and traffic ordinances.
In the event of an accident in the laboratory which involves a minor chemical release or spill (with no personal injuries):
- Accident reports
All laboratory accidents must be reported:
- Submit OSHA required occupational injury report and worker’s compensation claims to Human Resources.
- Report all accidents (including non-injury and near-misses) to Environmental Health and Safety for your respective campus.
- Fires and fire alarms
If a fire alarm sounds, laboratory workers should:
- Extinguish open flames (Bunsen burners, alcohol lamps etc.) and close the fume hood sash.
- Exit the building immediately to a designated assembly area.
- Report any incident information to the IU Police Department (IUPD) for your respective campus and stay available for a personnel count or any questions.
If a fire occurs, laboratory workers should:
- Pull the fire alarm and evacuate.
- Any employee may use an extinguisher to clear a route to make an escape.
- Employees who have received annual field training* in the use of extinguishers may use an extinguisher to fight an incipient fire but must evacuate if the fire is not immediately extinguished.
- To activate a fire extinguisher use the PASS method:
- Pull the pin.
- Aim at the base of the fire.
- Squeeze the handle, and
- Sweep from side to side.
If the fire is not extinguished after using one fire extinguisher then evacuate the building.
- Clothing can be extinguished using the Stop, Drop, and Roll method, a fire blanket, or the emergency shower.
- Water reactives and burning metals may be extinguished using a Class D fire extinguishing media (such as a bucket of dry sand or a commercial Class D fire extinguisher if available such as Met-L-X, Super-D, or Lith-X, etc.).
Note: Classification of fires and extinguishers - Class A, ordinary combustibles; Class B, flammable liquids and gasses; Class C, live electrical equipment; Class D, combustible metals and metal alloys. Most laboratories are equipped with combination Class ABC fire extinguishers. Some also have carbon dioxide Class B and Class C fire extinguishers for flammable liquids, gases, and electrical fires. A bucket of dry sand (marked “Class D Fire Extinguisher”) or commercial Class D fire extinguisher must be present in laboratories where water reactives and combustible metals and metal alloys are used.
* Insurance, Loss Control and Claims (INLOCC) approved annual field training
- Tornado watches and warnings (sirens)
A tornado watch means that conditions are favorable for the possible formation of a tornado. If a tornado watch is issued laboratory workers should:
- Monitor weather conditions or monitor your weather alert radio.
- Complete existing experiments to a termination point. Do not start any new experiments. Shut down equipment if hazardous conditions may result from loss of utilities (e.g. lossof coolant, vacuum, steam for autoclaves).
- Be prepared to terminate experiments immediately if conditions deteriorate and a tornado warning is issued.
- Complete any animal research activities in progress and be prepared to terminate activities immediately if conditions deteriorate.
- Confirm that all laboratory animals are moved to appropriate housing.
- Close any open containers, secure and protect valuable research samples, radioactive isotopes, biohazardous agents, recombinant materials and hazardous chemicals to prevent breakage and release.
- Secure chemical, radioactive, and biological waste.
- Secure any other regulated materials.
- Extinguish open flames and close all fume hood sashes.
- Unplug computers and all other electrical equipment (except refrigerators and freezers).
- Breakable items or items that may become airborne in heavy winds should be moved away from outside windows.
- Cover and secure or seal vulnerable equipment with plastic.
- Protect valuable files, research notebooks, and data to a safe secure location.
- Gather personal valuables and take them with you.
- Ensure you have your University issued ID with you.
- If a tornado warning is issued you must immediately suspend all laboratory procedures and seek shelter immediately.
A tornado warning means a tornado has been sighted in our area or nearby county. If a tornado warning siren is activated laboratory workers shall:
- Seek shelter immediately.
- Go to the designated tornado shelter.
- Basements, interior hallways and rooms on lower floors are the best locations for shelter.
- Stay away from windows and exterior doors.
- If no shelter is available, lie down in a low-lying area.
- Protect yourself from flying debris.
