The Safety and Risk Management Office must be notified prior to a laboratory move,
relocation, or vacancy for any reason in order to perform a laboratory close out assessment.
This procedure will ensure that all hazardous materials are accounted for and properly
disposed of and will prevent the next occupant from inheriting “unknown” or potentially
If you are relocating your laboratory, the Laboratory Relocation Guidance document is available for review.
Laboratory close out procedure
STEP 1: At least three months before you move, or as soon as reasonably possible,
review the Laboratory Closeout Procedure Checklist. It covers general points to help you safely and efficiently dispose of unwanted
lab materials and equipment.
STEP 2: At least 30 days before the move, schedule a tour of your vacating lab(s)
with Safety and Risk Management (firstname.lastname@example.org). During the tour, SRM will help you address any safety issues and devise a plan
to safely dispose of unwanted items.
STEP 3: After the laboratory move, submit the completed Laboratory Closeout Procedure Checklist to Safety and Risk Management. When the form is received, a safety officer will
conduct a walk-through of the vacated lab space to ensure that all hazardous materials
have been removed and the area cleaned and decontaminated.
30 days before the move
- Inspect your lab(s) again to be sure all unknown materials have been identified and
no new ones have been created while preparing to vacate the lab(s). It is productive
to repeat this step of the close out process, because identifying and disposing of
"unknowns" is a major cost item in laboratory close outs.
- All surfaces and equipment in the lab(s) will need to be disinfected, cleaned, or
decontaminated to assure that no biological, chemical, or radioactive contamination
- Check beneath hoods, in shared labs and equipment, and in freezers, refrigerators,
or cold rooms for biological, chemical, or radioactive materials that might easily
be left behind.
- Follow-up on the status of time critical close out plan steps such as: chemical and
radioactive waste collection and special equipment moving arrangements.
- Depending on the scale of the move, such as when whole buildings are vacated for demolition,
there may be designated waste collection events. You should use this opportunity
to get rid of old, unwanted chemicals. Smaller moves, or single lab moves, may not
have this available. You must work with SRM to ensure timely removal of chemical
- Assess all the chemicals in your lab(s). Unknown, highly reactive, or expired materials,
such as peroxide formers, can be extremely dangerous to move. Determine which materials
will still be used in active research projects and will be transferred to your new
space. Plan to dispose of any unwanted chemicals or chemicals that you know will
not be used in future research projects.
- All chemicals that will NOT be transferred to your new laboratory must be disposed
of through SRM. NEVER dispose of any chemicals by pouring them into sinks or other
drains, by evaporating them in hoods, or placing in the regular trash.
- Chemical waste will NOT be transported to your new lab location. All chemical waste
must be disposed of through SRM.
- Identify chemicals that may need special handling or containers to be moved, such
as compressed gas cylinders, poison inhalation hazards, air reactive chemicals, and
DEA controlled substances. Transport of these chemicals will be addressed during
your lab’s close-out procedure.
- Look for old supplies from past researchers. Many labs have inherited chemicals that
must also be identified and disposed of before moving to a new location.
- If you find unlabeled or unclearly labeled containers, make sure to label them with
full chemical name (not formula) as soon as they are located. Unlabeled chemicals
will not be moved. If you cannot identify the material, attach a waste tag, mark
it as “unknown”, and place it in your waste accumulation area for disposal.
- Mercury and mercury containing equipment, including mercury thermometers, pose special
risks during moves. Labs are strongly encouraged to dispose of mercury thermometers
through SRM as chemical waste prior to moving.
- Gas cylinders and lecture bottles that are no longer used should be returned to the
manufacturer. Cylinders that cannot be returned to the manufacturer must be disposed
of as chemical waste.
- Tubing and regulators connected to corrosive or hazardous compressed gas cylinders
should be detached using safe procedures such as purging and venting to a hood or
ventilated area. Contact SRM for assistance or direction with this process.
- Prior to leaving the old lab location, tubing and regulators must be removed from
all gas cylinders. Caps must also be placed on the cylinder, whether they are being
moved to your new location or being returned to the manufacturer.
- Assess all biological materials (recombinant DNA, microorganisms, cells and cell lines,
tissues, organs, body fluids, plants, insects, and any biologically-derived or -contaminated
media, etc.) in your lab and determine which materials will be transferred to your
new lab. Plan to dispose of unwanted materials as you normally would during an experiment.
- If you will be cleaning out a large amount of biological waste for autoclaving, work
with your waste coordinator and SRM to ensure that there will be sufficient containers,
and that autoclaved waste is removed in a timely fashion. Individual biological waste
bags should weigh 20 pounds or less.
radiological equipment & materials
- Notify SRM at least 30 days prior to moving x-ray equipment to ensure NC RPS registration
is completed in a timely manner.
- Notify SRM if any radioactive materials will be transferred to the new lab location
or disposed of as waste.
laboratory equipment & Surplus
- Equipment, such as biosafety cabinets, glove boxes, centrifuges, ovens, laminar flow
hoods, etc., must be decontaminated prior to being moved. Decontamination is the
responsibility of the lab. Contact SRM if you are unsure of the appropriate way to
decontaminate a piece of equipment.
- Clean and defrost refrigerators and freezers prior to moving the equipment.
Equipment Disposal & Surplus
- Unwanted or broken equipment, such as refrigerators, freezers, incubators, centrifuges,
vacuum pumps, etc., may be discarded through WCU Surplus. Equipment that could possibly
be contaminated with biological, chemical, or radioactive materials MUST be decontaminated
and cleared by SRM prior to surplus pickup. Lab personnel are responsible for equipment
decontamination prior to disposal. Submit the Equipment Clearance Before Surplus Form to SRM to schedule the clearance.
- Any equipment that may contain oils or refrigerants MUST be drained prior to disposal.
The oil is collected for hazard waste disposal.
transporting materials safely
- Hazardous materials, including, biological, chemical, or radioactive materials, must
not be moved in compromised containers. This is one of the major causes of spills,
so please ensure all containers are free from cracks and chips.
- Notify SRM if any hazardous materials, biological or chemical, will be transported
in any type of vehicle. This notification should be made as soon as possible so there
is sufficient planning time if special arrangements are necessary.
- Seek assistance from SRM in planning the removal or safe transfer to your new lab
of any materials that may need special handling or containers (compressed gas cylinders,
poison inhalation hazards, air reactive chemicals, and DEA controlled substances)
as identified during the chemical inventory assessment.
- Separate chemicals by the following hazard class and transport with sufficient packing
material to prevent bottles from breaking: Inorganic oxidizer, flammable liquid, inorganic
acid, inorganic base, organic acid, oxidizing acid, flammable solid, organic compounds
not listed in former groups, inorganic compounds not listed in former groups.
- Avoid transporting hazardous materials alone and never transport in a personal vehicle.
- Have boxes, plastic bags, and containers for broken glass, etc., ready and available
before the move begins. Spill clean-up materials should be available at the time of
the move in case there is a spill while packing or unpacking.
- Biological, chemical, and radioactive materials must be transported in secondary containment
(even when just moving a few doors down the hall).
- Package and move lab items only during normal business hours (8:00 a.m. - 5:00 p.m.)
so staff will be available to help if there is a spill or accident.
- Wear appropriate personal protective equipment (PPE) for the materials being handled
(safety glasses or goggles, lab coat, gloves, closed-toe shoes, etc.).
- Back pain, often caused by heavy lifting, is one of the most common work-related injuries.
Apply the following ergonomic principles to prevent injuries and maintain a healthy
- Keep your head up and maintain the natural curve in your back
- Tighten your abdominal muscles before you lift
- Plan ahead and before lifting test the weight you are about to lift
- Share the load, if it is too heavy ask for help
- Hold objects close to reduce pressure on your back
- Pivot with your feet when lifting, don’t twist
- Lift with your legs while keeping your back in a neutral position
OCCUPYING THE new laboratory
- Have boxes, plastic bags, and containers for broken glass, etc., ready and available
before you begin unpacking. Spill clean-up materials should be available while unpacking
in case there is a spill.
- Review the location of safety showers, eyewashes, fire extinguishers, and all available
means of exit from laboratories and the building for your new location. This should
also include the designated meeting site for your new building.
- All biological safety cabinets must be certified again after the move to ensure filter
- Schedule a radiation survey with SRM for any x-ray equipment that has been relocated.
- Submit a new Laboratory Registration Form to SRM. Updated door signs with emergency contact information will be posted by SRM.
- Submit an updated chemical inventory for the new location.
- Submit an updated biological agent inventory to SRM for the new location.
- Submit an updated Laser Registration form to SRM.
- Make sure any required warning signs for radioactive materials, biohazards, lasers,
etc. are posted in your new lab location.
- Update your Lab Specific Chemical Hygiene Plan (CHP) and SOPs as needed to address
the new locations of safety equipment (i.e. eye wash, safety shower, fire extinguishers).
