           RISK ASSESSMENT FOR A LABORATORY PROCEDURE

                                           Technique Title
       Developing X-Ray films


                                            Staff involved
       All CSC staff that may need to develop X-ray films


                                          Hazards involved
       Chemicals: Developer, Fixer


                                         Route of exposure
       Skin, eyes, inhalation


                                                Harm
       Chemicals: The respective COSHH forms for the above substances must be read prior to
        this technique commencing so that their hazards and control measures are understood.


 Identify any persons and any special risks associated with the technique and steps that
                           must be taken to minimise them.
       Person carrying out the work: All chemicals, reagents and associated techniques used in
        this protocol will have their associated risks and control measures so their relevant COSHH
        forms should be read in conjunction with this protocol. It is important not to spend too long
        in the room (4S5) as it is not as well ventilated as it should be.
       Other Persons: There is no risk to anybody else unless they are in the room with the
        person carrying out the task.

       Controls 1: All new staff and students have a laboratory induction to ensure that they
        understand all of the safety considerations associated with the work carried out within this
        laboratory. All techniques are explained and demonstrated to all new staff and students.
        Staff are sent on the appropriate training courses offered by the MRC to ensure they are
        familiar with all aspects of good laboratory practice.

       Controls 2: Appropriate PPE is always worn as well (Nitrile or Latex Gloves and Lab coat
        etc. eye protection if developer and fixer are being made). No eating and drinking is
        allowed in CSC labs either so there is no real risk of ingestion of chemicals.


                                  Emergency Spillage Procedure
       All chemicals in the protocol will have the relevant spillage listed in its own COSHH form
        and all staff should familiarise themselves with these procedures.
       All accidents must be reported to the Lab Manager / Safety Supervisor or the
        departmental first aid personnel, and CSC Safety via an accident report form:
    http://safety.csc.mrc.ac.uk/CSCAccidentReportForm.pdf


                                           Waste Disposal
       Unwanted films should be disposed of in the bin in the room.
       The Developer is plumbed in to purification equipment and the drain so all waste chemicals

                                                                                     London W12 0NN



                                           Waste Disposal
        is disposed of correctly



                      Include a brief stepwise description of the technique
       Put on your lab coat and take some gloves with you to the X-Ray developer (4S5)
       If the machine is off when you want to use it, switch it on using the switch underneath the
        film feeder. Leave to warm up for about 30 minutes. Chemicals should be at 370C for
        optimal results.
       Switch on the water flow by turning the right hand water tap on the wall 90 o anti-clockwise
        and similarly with the left hand tap. Leave the central tap as it is. The water pressure
        regulator underneath the bench should already be set at 2lb/in2.
       Ensure the chemical reservoirs have enough chemicals in them. DON’T ASSUME
        SOMEONE ELSE WILL DO THIS.
       Contact Dr. Steve Marley if the solutions are running low, if he is not available you will
        have to make them up yourself
       For the Developer:

                 Add the contents of the small bottles marked B & C to the large container marked A
        &         mix thoroughly.


       For the Fixer:

                 Dilute the concentrate 1 in 4 with water and add to the storage container. It does
        not       have to be distilled water; tap water is adequate.

       Lock the door, switch off the lights and put your film through the processor, it should take
        approximately 2-3 minutes to process each film.
       Once you have finished processing your films, write your Name, the date, department,
        grant code, and the number of films you have put through the developer. Failure to do this
        could result in your or your group from being banned from using this piece of shared
        equipment.
       Ensure the room is left clean and tidy after you have finished so the developer is ready for
        the next person.
