Chemical spills:

Lab PPE – Lab coat and gloves should be worn when undertaking any procedure in the lab. Safety glasses can be found in the last bay in the top drawer under the plate shaker and should be worn when handling strong acids and bases, fuming and corrosive substances. A full face shield must be used when handling liquid nitrogen and when taking out heated liquid from the microwave oven. The fume hood is located in the chemical room.

Accidents, incidents and near misses 

The chemical spill kit and mercury spill kit are located under the main lab sink. There is a further chemical spill kit and safety signs located near the stores window. Before clearing hazardous spills, check the MSDS for any special measures. In the event of a mercury spill, evacuate the area for 30 minutes, don protective clothing and respiratory mask before clearing spill. The mop and bucket are located in the cell culture room.

First aid kits are located in both the office and lab corridors of L1 in the middle of the building.  If you need to 

Accidents/incidents and near misses can be reported Accident/Incident and near miss reporting: "It is important that the Campus Health and Safety Service are made aware of any incident on the Campus that has lead to someone being injured or made ill, or to property or equipment being damaged. We also need to know about those incidents that could have led to someone being injured or made ill, or to property or equipment being damaged - a 'near miss'.

L1 Induction and Rules

Updated 11th September 2021 

New Staff/Student Induction for 2021/22 

General Points 

To keep the lab running smoothly, we have a standard operating procedure for all communal  equipment and areas. Keep these areas tidy by cleaning up afterward and putting things back in the same  place and condition as you found them.  

If you are unsure about anything, ASK. It is always better to check before you do it. 

New technicians, UG and PG students, and post-docs should be given a tour of the wet lab area by  one of the current L1 technicians or the L1 Safety Officer BEFORE starting lab work. 

ALWAYS wear a lab coat in the wet lab area. 

Mobile phones should NOT be used in the wet lab area. Always set your mobile to silent mode in  L1 write-up areas. 

The use of headphones in the lab is strongly discouraged. 

NO lab coats or gloves should be worn outside the wet lab area, unless you are transporting  something that requires you to wear these items. DO NOT open doors outside the wet lab area with  a gloved hand. 

UNDERGRADUATE STUDENTS ONLY: All bags and backpacks must be stored in the lockers  located on the landing outside the entrance to L1 corridor. Coat hooks are available in the write-up  areas for jackets, etc

Use of Communal Equipment / Areas 

Lab Consumables (gloves, tissues, pipette tips, blue roll, etc.) 

  • If a consumable item is running out, please write it on the whiteboard for ordering. Communal items are currently stored in room L146. 

Microwaves and Heating Blocks 

  • DO NOT heat solutions in closed or partially closed vessels. If you do, a dangerous  pressurised vessel will be established which will eventually explode. Use an open vessel  that will allow the pressure to escape. 
  • Any spillages in the microwave/heating block must be cleaned up even if the substance  is not hazardous. 

Centrifuges (Beckman L7 Ultra and Optima TL Ultra, Sorvall and Sigma) 

  • New members of staff must receive departmental training (email: biol-infrastructure before using the Beckman L7 Ultra, Beckman Optima TL (in room  L131), and Sorvall centrifuges for the first time. Undergraduate students must be  supervised at all times by a trained member of staff when using these centrifuges. 
  • Sorvall (Lynx 6000) high-speed centrifuges and the Beckman ultra-centrifuge must be  booked online before use. Please also book the rotor you plan to use.  

( then click on  “Online Booking System” at top right of web page) The details of your centrifuge run(s)  and a valid workorder code must be recorded in the logbook (next to centrifuges). Do not take someone else’s booking without their permission. Any machine found to be  running, but not booked, could be switched off. 

The booking information on the web should be completed as follows: 

  • Always give a contact phone number and your name – your email is  

automatically recorded. 

  • In the description box record the number of runs to be carried out and any  hazard. 
  • Your PI or group name should be given instead of grant code. 
  • You must receive training from Dr. Christoph Baumann  ( before using the bench-top Sigma centrifuge for the  first time. You must enter a code to use the Sigma centrifuge.  
  • The bench-top Sigma centrifuge must be booked before use. Do not take someone else’s  booking without their permission. DO NOT overfill Falcon™ tubes when using this  centrifuge (max. of 10 ml in 15 ml tube, max. of 35 ml in 50 ml tube). 
  • Tubes MUST be accurately balanced by weight to within 50 mg (not by eye) and tube  type, i.e. a Centricon™ must be balanced with another Centricon™ and not a Falcon™  tube. 
  • When a centrifuge is switched on, the lid must be closed to allow cooling. Before starting each run, make sure the rotor lid is screwed onto the rotor. This holds the  rotor in place during the run. 
  • When finished, check the rotor for spills, switch off the centrifuge and leave the lid  open. Remove the rotor from the Sorvall centrifuges when finished. Leave the rotor in  the Sigma centrifuge when finished. 
  • If any spillages occur, clean both the rotor and the inside of the centrifuge, and  decontaminate if necessary. Only use 1% (v/v) Neutracon detergent for washing the  rotors. Afterward rinse rotor with plenty of water, then oil with slushing oil (see Dr.  Christoph Baumann for oiling instructions). 
  • Always wear gloves when touching any part of the gel-doc system, including the PC.  This avoids personal contamination by ethidium bromide (even when your gel does not  contain it). 
  • Take care when changing between the trans-illuminator and the white-light box. The  white-light box must be placed vertically at the back of the light-proof cabinet using the  clips provided for it. New users must receive training from an experienced user before  using the gel-doc system unsupervised. 
  • When moving the trans-illuminator box back and forth, please ensure that the cable  connected to the white-light box is not caught in the tracks. 
  • DO NOT pour liquid directly onto the trans-illuminator or white-light box. Ethanol and water bottles, and tissues are placed in the gel room to clean the light-boxes  after use. If these run out while you are using them, or are running low, please fill them  up. Do not leave empty bottles or boxes in gel-doc room. 
  • Once you have taken your photo, leave the computer on with the Gene Snap programme  open. Please close your image window when finished. You do not need to switch off the  computer or gel-doc system. 
  • Extra printer film is available in the drawer under the PC. When you use the second to  last roll of film, please write it on the whiteboard for ordering. 
  • Make sure you back-up your data as this is NOT done automatically.

Chemicals Room 
  • Chemicals must be put back in the correct place (alphabetical order) on the shelves or in  the cupboard after use. No chemicals should be stored on the benches as there is plenty  of room on the shelves. 
  • Any spillages must be cleaned up even if the substance is not hazardous. This involves  cleaning the area around the balance as well as the top of the balance. 
  • Water bottles must be filled up with ultra-pure deionised water, not left empty or nearly  empty. Do not replace empty bottles with a full one from the main lab. 
  • Tissue boxes must not be left empty. Replace with a new box. 
  • Do not leave empty chemical containers in the Chemicals Room or fume hoods. Wash  them out with plenty of water (if not hazardous), remove hazard labels and dispose of  the container in the appropriate bin (red glass recycling bin or recycling bin for plastics). 
  • Empty glass Winchester bottles should be washed out with plenty of water and saved for  disposal of liquid chemical waste. Clean, empty Winchester bottles can be stored in the  Chemicals Room on the floor under the bench to left of the fume cupboard and used as  needed for the disposal of liquid chemical waste. 
  • Empty plastic 2.5 liter solvent bottles should be washed out with plenty of water,  labelled with a recycling label (in top drawer beneath balances in Chemicals Room), and  returned to Biology Stores for recycling (see below). Do not leave empty bottles in the  fume hood. 
  • If a chemical is running out, check in the chemical cupboard for another. If there is none  left then write it on the whiteboard for ordering (communal items only). 
  • Switch off the balances and pH meter after use. The pH probe should always be stored  in 3 M KCl when not in use – make sure the end of the pH probe is covered by solution. NEVER use an open flame in any of the fumehoods! 
Gel Room 
  • If possible, all groups should use SYBR Safe DNA gel stain (Invitrogen) for their work  as an alternative to ethidium bromide. Wear gloves when handling SYBR Safe as the  gel electrophoresis equipment may be contaminated with ethidium bromide. 
  • If using ethidium bromide for agarose gels please take care as it is carcinogenic and  mutagenic. Work in the designated area only (on the mat) on the bench. 
  • Agarose gels and any other items, e.g. gloves and tips, contaminated with SYBR Safe or  ethidium bromide can be disposed of in a yellow non-hazardous identifiable lab waste  bag. 
  • Wash out your gel equipment in the sink and leave to dry on the side where the agarose  gels are prepared, not next to the sink where the PAGE equipment is stored. 
Constant Temperature (CT) Rooms 
  • ALWAYS log your use of all warm room shakers. There are forms for this purpose in the CT rooms. 
  • Book the shaker for 2.5 liter flasks in advance using the diary in the warm room. Do not leave things in the rooms unlabelled or for long periods of time without booking  it. Things left in this manner will be autoclaved and discarded. 
  • Do not store items on the benches in the cold room for extended periods of time. All  items should be labelled with your name and date. Bench-top areas are reserved for  conducting experiments or protein purifications. 
  • Please check that the door of the 37˚C room closes completely as it has a tendency to  wedge itself open.
  • Never open your liquid cultures in the warm room to remove samples as this risks a  phage contamination. 
Laminar Flow Hood 
  • Please use the laminar flow hood (room L131) for handling sterile materials whenever  possible to reduce the use of expensive gas canisters. 
  • Agar plates streaked with bacterial culture should NOT be dried in the hood. The hood  should remain a sterile environment – no bacterial cultures! 
  • Label all freshly poured sterile plates before leaving them in the hood to cool and dry. The inside of the laminar flow hood should be wiped with 70% (v/v) ethanol before and  after use. 
Class II Microbial Safety Cabinet 
  • This cabinet (room L131) can be used to handle Category 2 micro-organism(s), but you  must consult with your PI and an experienced user before using it. A Biological Agents  Risk Assessment for handling the micro-organism(s) must be completed and approved  by the Departmental Safety Officer (Dr. David Nelson) before using the cabinet. 
  • The cabinet should be booked in advance using the hard-copy diary located on the left hand bench in room L131. 
  • The inside of the cabinet should be wiped with 70% (v/v) ethanol before and after use. When finished with your work all items should be removed from inside the cabinet. 

Waste Disposal 

ALL LAB CONSUMABLE WASTE AND GENERAL WASTE MUST BE DISPOSED OF in  either a clear autoclave bag, a `tiger´ bag, or a black `general waste´ bag (by hand wash sinks  only) depending on its level/type of contamination (see below). Some decontaminated, plastic  lab consumables can be recycled – see below for more information on the L1 Green Impact  recycling scheme. 

RESIDUAL CHEMICAL MATERIAL is defined as a non-hazardous concentration.  Information on Chemical Waste Threshold Levels can be found on a poster in the L1 Chemicals  Room. 

DRY ICE SHOULD NOT BE POURED INTO THE LAB SINKS. Unwanted clean dry ice  should be placed in the blue insulated box located in room L131 so it can be used by other  groups. Dry ice contaminated with organic solvent should be left to sublimate in the fume hood. 

Lab consumables 
  • Heavy-duty `tiger´ bin bags (`Non-Hazardous Identifiable Lab Waste´) 

o `Tiger´ bags should be used for non-hazardous identifiable lab waste, which does  not require incineration or autoclaving. Black bins containing these bags must be  labelled `Non-Hazardous Identifiable Lab Waste Only´ (labels are available  from Biology Stores) – wire racks should not be used to hold `tiger´ bags. We pay a significant disposal charge for every ‘tiger’ bag removed from the  Department – therefore, these bags should only be used for non-hazardous  identifiable lab waste that cannot be recycled or disposed of in a black `general waste´ bag. L1 has implemented a recycling scheme for some commonly used, plastic  lab consumables, e.g. serological pipettes, 15 ml and 50 ml screw-cap tubes,  micro-well polystyrene plates, polystyrene tubes, and syringes.

Please see Reyme Herman (in Thomas group) for more information about our lab  plasticware recycling scheme. 

o Significant volumes of non-hazardous liquids must NOT be place in the `tiger´ bags. Only residual liquid contamination of waste is allowed. For this reason, all  non-hazardous liquids must be poured down the sink before putting a tube/container in the `tiger´ bag. 

o Items contaminated with biological (human/animal tissue or fluids) or  microbiological/GM agents must NOT be disposed of via these `tiger´ bags.

o Individual groups are responsible for closing and removing full bags in their lab  areas (see next bullet point). The individual group responsible for the weekly L1  Glassware Rota will remove full bags in communal lab areas, i.e. Chemicals  Room, Gel-Doc Room and Gel Electrophoresis Room.  

o L1 lab staff are responsible for closing full `tiger´ bags (3/4 full or < 10 kg) with  cable ties (Biology Stores code SHE6000), labelling with laboratory ID details  (i.e. `L1 Communal´) and placing them near to the ice machine for collection by  the cleaning staff. A supply of the heavy-duty `tiger´ bin bags, ID labels and  cable ties can be found in the Chemicals Room. 

o Uncontaminated pipette tips, or those contaminated with residual chemicals,  must be placed in a `tiger´ bin bag. NOTE: It is recommended that pipette tips  are collected in disposable plastic jars (available from Biology Stores) before  disposal in a `tiger´ bin bag when full. 

o Uncontaminated pipettes, or those contaminated with residual chemicals must be  placed in Bio-Bin `pipette bins´ to avoid puncturing or splitting `tiger´ bags.  Once a Bio-Bin is full, it should be sealed and placed into a `tiger´ bag for  disposal. Individual groups should purchase Bio-Bin pipette bins from Biology  Stores. 

o Empty plastic chemical containers can be put in `tiger´ bin bags (or washed and  recycled, see below).  

o Weigh boats, micro-titre plates, centrifuge tubes, empty FPLC fraction collection  tubes, disposable plastic flasks, petri dishes (no agar or bacterial contamination)  and buffer filtration devices can be placed in `tiger´ bin bags if they are NOT  contaminated with biological/microbiological agents, or they only contain  residual chemical material.  

o All lab tissue and blue roll contaminated with residual chemical material can be  placed in a `tiger´ bin bag. 

o Uncontaminated gloves or gloves contaminated with residual chemicals should  be placed in the `tiger´ bin bag. 

o Polymerised acrylamide gels can be disposed of in these bags. 

o Empty gas canisters should be placed in the box near the ice machine for  recycling. 

  • Large yellow bins (`Clinical Waste´ for incineration) 

o Lab waste (tissue, blue roll, tubes, gloves, pipettes, pipette tips, plasticware, etc.)  contaminated with hazardous concentrations of any chemical should be placed in  large yellow bins. Information on Chemical Waste Threshold Levels can be  found on a poster in the L1 Chemicals Room. 

o These large yellow bins can be purchased from Biology Stores by individual  groups. 

  • Small yellow `sharps´ bins 

o All `sharps´ waste, glass vials, NMR tubes, glass ampoules and glass Pasteur  pipettes should be disposed of in these bins, NOT the red glass recycling bin (see  below).

o The `sharps´ bin must NOT be filled above the designated level. If the bin is full,  seal the container and replace with a new one. A communal supply of new  `sharps´ bins are stored in room L136 (under the sink). These small yellow bins  can be purchased from Biology Stores. 

o Glass crimp-top HPLC vials must be disposed of in these bins, NOT the red  glass recycling bin (see below). 

  • Incineration `Anatomical Waste´ bag 

o This type of waste disposal bag is not in use on L1 corridor. Please see the L1  Safety Officer if you need to start using these bags. 


Liquid waste 

o Decontaminate with Virkon™ (final concentration = 1% w/v) for 1 hour (or  alternatively use Presept). Chloros can only be used on glass containers. 

Solid waste 

o Place in a clear autoclave bag and send for autoclaving (see guidelines below). o Where an autoclave bin (rather than a wire rack) is used it should be labelled  'Autoclave Waste Only' (labels available from Biology Stores). 

o Pipettes contaminated with bacterial culture should be placed in a small  autoclave waste bag. They should not be mixed with other solid waste in a large  autoclave bag as there is a risk of puncturing the bag. 

  • Most chemicals can be washed down the sink with plenty of water. Those that cannot be  washed down the sink must be placed in a clearly labelled GLASS waste bottle and  taken to Biology Stores for disposal. 
  • Clean, empty Winchester bottles can be found in the Chemicals Room on the floor  under the bench to left of the fume cupboard, or obtained from Biology Stores. 
  • Wash out glass chemical bottles thoroughly with water, remove hazard labels and  plastic closures, and place in the red glass recycling bin (in room L138). 
  • Empty glass Winchester bottles should be washed out with plenty of water and saved for  disposal of liquid chemical waste. Clean, empty Winchester bottles can be stored in the  Chemicals Room (room L138) on the floor under the bench to left of the fume cupboard  and taken as needed for the disposal of liquid chemical waste. 
  • Make sure you remove all hazard labels from the glass waste before placing it in the red  glass recycling bin or taking it to Biology Stores. 
  • Small glass pipettes in the gel room must be discarded in the yellow `sharps´ waste bin,  NOT the red glass recycling bin. 
  • All glass microscope slides and cover slips must be discarded in a yellow `sharps´ waste  bin, NOT the red glass recycling bin. 
  • All glass crimp-top HPLC vials must be disposed of in a yellow `sharps´ waste bin,  NOT the red glass recycling bin. 
  • DO NOT dispose of fluorescent bulbs, tungsten bulbs or mercury lamps in the red glass  recycling bin. These should be taken directly to Biology Stores for disposal – mercury  lamps will be sent to Chemistry for disposal. 
  • Do not leave empty plastic chemical containers in the Chemicals Room or fume hoods.  Wash them out with plenty of water (if not hazardous), remove/cross out hazard labels and dispose of the container in the appropriate bin (lab recycling bin or `tiger´ bag). Everyone should recycle plastic packaging and containers where possible. Empty plastic 2.5 liter solvent bottles should be washed out with plenty of water, a  recycling label affixed on top of solvent label without covering up the solvent name, and  returned to Biology Stores for recycling. Recycling labels are stored in the drawer  beneath the balances in Chemicals Room. Do not leave empty bottles in the fume hood. 
Paper and Cardboard 
  • Paper packaging can be placed in the lab recycling bins. 
  • Flatten out cardboard boxes/tubes and place in the cardboard recycling bin near to the  ice machine. 

All research groups on L1 share communal glassware. This glassware is stored in labelled cabinets  along the windows. When you finish using a piece of glassware, you should wash it with soapy  water, rinse well with tap water followed by deionised water (green tap), then place it in the  communal drying oven. Glassware should not be left to dry next to the sinks as this poses a safety  hazard. All lab glassware breakage should be recorded on the sheet posted near the whiteboard.

All research groups are responsible for their own autoclaving. You should discuss the local rules  for autoclaving items with your PI. The following notes are for guidance only. 

Routines for safe disposal of waste 

  • All waste must be double-bagged, and the outer bag taped and labelled with PI’s  surname and floor number (L1). 
  • Autoclave bags MUST NOT be overfilled – half full is ideal. They must fit into the  autoclave buckets allowing steam penetration of the contents.  
  • `Sharps´ (including syringe needles and razor blades) MUST NOT be put into autoclave  bags. 
  • Empty gas canisters should NOT be placed in autoclave bags. 
  • Chemicals that vaporise, i.e. those handled in a fume cupboard, must not be put into  autoclave bags. 
  • Puncturing of bags by plastic pipettes or cocktail sticks will be recorded as an incident.  Cocktail sticks should be put into a plastic tube or wrapped in paper. 
  • Prior notification is required for the handling and autoclaving of blood and tissue  products.

Sterilisation of clean media, plasticware and glass items 

  • Media must be contained in suitably sized glass or plastic container. Contents should not  exceed 2/3 of full volume to prevent spillage. Use the following guidelines when filling  containers with media/agar: 

o 100 ml bottle (max. volume = 60 ml) 

o 500 ml bottle (max. volume = 300 ml) 

o 1 liter bottle (max. volume = 650 ml) 

o 500 ml conical flask (max. volume = 250 ml) 

o 1 liter conical flask (max. volume = 600 ml) 

  • Tops of bottles should be “cracked” open to allow for expansion.
  • Media containers and tip boxes must be labelled with group initials and floor number,  and sealed with a small piece of autoclave tape. 
  • Autoclave runs for sterilisation of media, glass and plasticware are scheduled at the  following times each work day (subject to change): 10:30 and 13:30 (items available for  collection the next work day). 
  • If you have a large number of items for autoclaving, e.g. 6 x 500 ml conical flasks,  please let the Autoclaving and Glass washing (A&G) Staff know (email: biol one day in advance. 
Lone Working in the Research Labs 

If a postgraduate research student or post-doc is working outside normal working hours in the  laboratory, all work must be inherently low risk. A formal risk assessment is required for higher  risk lone working activities. Guidance on lone working in the laboratory can be found on the  departmental website: (excerpts from website below) 

Lone working represents a situation where a person has neither visual nor audible communication  with someone else who can summon assistance in the event of an accident, illness or other  emergency. Lone working can, therefore, include those work activities undertaken both: during  normal departmental working hours (8.00-18.00 weekdays) and outside normal departmental  working hours (includes weekends and holidays when the University is closed).” 

“Supervisors of all lone workers must be satisfied that an individual has received appropriate  training and has the necessary experience before allowing lone working. It is good practice for  those individuals working outside normal working hours to inform a friend or family member of  their location and approximate time of return.” 

Undergraduate Project Student Supervision 
  • No undergraduate (UG) student is allowed in the lab before 9:00am or after 5:00pm without  direct supervision – a student must arrange for supervision BEFORE starting their  experiments. It is not sufficient to have a supervisor in the dry area – students must be  accompanied in the wet lab by a supervisor. 
  • UG students cannot work after 7:00pm Monday-Friday, or on the weekends. If an UG  student must conduct lab work outside normal departmental working hours then the project  supervisor must give permission in advance by completing the out of hours permission form
  • All accidents should be reported to your supervisor and the L1 Safety Officer (Dr. C.G.  Baumann).
