					                                      UCD RISK ASSESSMENT – UCDF28
                                          DISSECTION / SURGERY

Dissection and surgery works involving the use of blades and similar equipment is routinely carried out
throughout the Veterinary Science Centre and Veterinary Hospital. Persons engaged in such activities run the
risk of being cut by blades and or being exposed to infectious agents.

                                                  Persons At Risk
The persons undertaking the works are at risk.

   Risk Assessment
                                        Likely                    Harmful                      Moderate Risk
                                      Measures Required To Reduce Risk
1. Persons engaged in dissections and surgery operations must observe excellent personal hygiene practices.
    To this end all persons must:
    o     Cleanse or wash their hands after dissections and surgery and prior to leaving their workplace or using
          the telephone, computer or any other equipment
    o     Not insert their hands or fingers or any pieces of equipment e.g. pens, into their mouth / eye / nose / ears
          whilst engaged in dissections or surgery
    o     Cover all cuts, abrasion and skin lesions with a waterproof dressing at all times
    o     Ensure that protective clothing is worn when engaged in dissections or surgery and is removed before
          leaving the working area and is laundered on a regular basis
    o     Ensure that gloves are worn when engaged in dissections or surgery
    o     Ensure that no food or drink is consumed in the working area
2. Good sharps practices must be adhered to at all times:
    o     Always handle blades with care
    o     Use the appropriate blade for the task. Do not use scalpel blades or razor blades unless absolutely
          necessary and when in use handle them with care
    o     Wherever possible use single unit disposable scalpels rather than changing the blades on a re-useable
    o     If not being disposed after use blades must always be placed in a safe position and orientation so as to
          avoid possible accidental injury to others. Do not leave scalpels pointing upwards from beakers or similar.
    o     Where a blade is used in a holder, particular care must be taken when changing the blade. The blade
          should not be held in the fingers during the process and the use of excessive force must be avoided.
    o     When working at a cadaver / sample / patient only one person at a time should be holding / working with
          a blade
    o     Always cut away from your body and away from others
    o     Do not pass cutting or sharp instruments from hand to hand
    o     Do not turn around with cutting equipment in the hand
    o     Use round nose scissors whenever possible.

    o   Place used sharps directly into a sharps bin for disposal (have a sharps bin available at the point of use
        to enable immediate disposal). Do not overfill sharps bins, fill only as far as the fill line.
    o   Cuts caused by sharps should be treated immediately. Wash well under running water and cover with a
        dry dressing. An attempt should be made to identify any chemical or biological hazard in the needle that
        may have been injected. Apart from very minor injuries, a First Aider should be called. In the event of
        sustaining an accident resulting in a wound:
               Immediately wash the wound liberally with soap and water but without scrubbing
               Gently encourage free bleeding of puncture wounds but do not suck the wound
               Dry the area and apply a waterproof dressing
               Seek medical advice if the sharp concerned was contaminated with any hazardous materials
               There is no evidence available to show that using antiseptics or squeezing a wound will reduce
                the risk of transmission of a blood borne pathogen. Using a caustic agent such as bleach to wash
                a wound is not recommended.
3. Dissection / surgery tools should be kept clean, sharp and free from rusts.
4. Clean or dispose of equipment after every dissection / surgery.
5. Design systems of work so as to eliminate aerosol formation.
6. Properly mount / position dissection specimens. Do not dissect a specimen while holding it.
7. Refer to UCDF4 Zoonoses (General) Risk Assessment; UCDE9 Use Of Sharps (General) Risk Assessment;
    UCDE23 Laboratory Personal Hygiene (General) Risk Assessment; and UCDD4 Use And Handling Of
    Biological Material Of Human And Animal Origin (General) Risk Assessment for further information.

Preserved Specimens
1. Avoid contact with preservative chemicals.
2. The use and handing of preservation chemicals may require the completion of a chemical agents risk
3. Rinse preserved specimens completely before dissection.
4. Wear safety goggles / glasses to prevent the splashing of any preservation chemicals into the eyes.
5. Wear gloves and protective clothing.
6. Know where the nearest supply of clean running water is located.
