Dissection Safety Rules
Dissection Safety Rules
- Conduct yourself in a responsible and safe manner at all times during the dissection.
- Wear safety glasses while you are dissecting even if you wear glasses or contact lenses. Contact lenses can hold chemicals in the eye(s) increasing the potential damage in the event of an accidental splashing of chemicals into the eye(s).
- The squid has been preserved with a safe chemical and the classroom doors will be cracked open to allow fresh air in the room. However, if you need to take a break or the odor is beginning to bother you, notify the teacher.
- Avoid contact with preservative chemicals. Keep your hands covered with the plastic gloves at all times. Rinse the squid completely before dissection.
- Use the proper procedures described by the teacher and keep the squid on the dissecting tray. Do not dissect the squid while holding it.
- Handle the scalpel or scissors with extreme care. They are sharp enough to cut through skin.
- Always cut away from your body and away from others.
- Never remove squid/squid parts from the classroom. Properly dispose of dissected materials.
- Clean up the work area and return all equipment to the proper place when the dissection is completed.
- Carefully wash your hands for a minimum of 15 seconds before returning to your seat.
Figure 1 shows the dissection equipment you will use in this investigation.
A. Teasing or Dissection needle which used to pull apart muscle tissue,
B. Dissecting scissors which is used to cut through tissue, and
C. Forceps, which is used to lift and move cut tissue.
Figure 2 shows different types of dissecting pins. Dissecting pins are used to hold the squid in place in the dissecting tray. They are also used to hold back the mantle so you can observe the internal organs.
Figure 3 shows a dissecting pan. The dissecting pan holds the squid as you dissect it. We will be using a plate. At the end of the dissection, you will remove the squid and discard it in the trashcan.
