Research and write up a Full Risk Assessment for the titration. You will need to bring your Risk Assessment to your Core Practical 3 Laboratory session so that you can follow it.
1. Carry out research to develop a Risk Assessment. Ensure you make your precautions relevant to the correct chemicals and the concentrations and volumes being used. Hazcards 32,91A,47A. (It is recommended that you read the procedure on the next page first.)
CPAC 3a - Identifies hazards and assesses risks associated with these hazards, making safety adjustments as necessary, when carrying out experimental techniques and procedures.
Complete full risk assessment prior to task
1. Include chemical hazards reactants & products plus physical hazards
2. Take account of volumes used to ensure risk assessment is appropriate
3. Take account of concentrations used to ensure risk assessment is appropriate
4. Make appropriate assessment of hazards and risks to do with the practical procedure itself
5. Reference hazcards used to plan for safety (CPAC 5b may be awarded if referenced)
CPAC 5a - Uses appropriate software and/or tools to process data, carry out research and report findings.
Carry out suitable research to support your risk assessment
Writes up a risk assessment in your own words specifying precautions relevant to practical being carried out
CPAC 5b - Sources of information are cited demonstrating that research has taken place, supporting planning and conclusions.
Carries out research to support planning by writing a risk assessment to prepare for safety before practical
Cite within text as necessary
Reference Hazcards in a bibliography in such a way that the reader may retrieve the information easily.
