Risk AssessmentLegal RequirementCarried out before work startsIdentify hazards
Look at controls in placeEvaluate the risk (likelihood)What improvements are needed?Incorporate precautions in SOPsSee School ProceduresUniversity Safety Office - New Researchers Talk
“Hi, I’m David and I’m invincible”Slide18
Risk AssessmentUniversity Safety Office - New Researchers TalkHAZARDthe
potential of something to cause harmRISKthe likelihood of an event occurring which will allow the hazard to occurThink of an activity outside of the UniversityList the hazards
List the control measures that reduce the riskSlide19
Training vs CompetenceAttending training is one thing, being competent to carry out an activity is another.You should have evidence of both training and achieving competence
Some schools use postgraduate supervisory requirements form (PSRF) -personal to you and confirms what supervision you requireKeep a record of allExternal coursesUniversity coursesLab-specific training (procedures and/or equipment)Records should show who has trained you and whenUniversity Safety Office - New Researchers TalkSlide20
Accidents and First AidReport all incidents whether injuries or ill-health (to your line manager/safety officer)Know how to call a first aiderKnow how to call for an ambulance8888 or 0115 9518888
It may be you, it may be a friend, it may be nothing to do with the work – know how to helpUniversity Safety Office - New Researchers TalkSlide21
Fire Safety – What you should know
Evacuation Procedure Call point location Escape route(s) Assembly point
University Safety Office - New Researchers TalkSlide22
Fire ProcedureIf you discover a fireRaise the alarmDial 8888 (0115 951 8888)Leave the building by nearest exit
Close doors and windows behind youReport to assembly pointOnly use extinguisher if:Small, contained fireConfidentClear exit routeUniversity Safety Office - New Researchers TalkSlide23
Fire ProcedureOn hearing alarm - leave building by nearest exit
- closing doors/widows - go to assemblyNotify if known false alarm – 8888(Mobile 0115 9518888)University Safety Office - New Researchers TalkSlide24

COSHH AssessmentDecide on control measuresEliminate or substitute, justify use.Engineering - contain, extract (FCs/MSCs)
Personal protectionTraining, supervisionHealth surveillance/screening/vaccinationOther considerations - Storage
- Transport - Disposal - Emergencies – leaks, spills - Nanoparticles
University Safety Office - New Researchers TalkSlide36
NanoparticlesOne or more external dimensions in the order of 100 nm or less ie: < 0.1 micrometre / micronUniversity Safety Office - New Researchers Talk
MSDS for micron-sized particles of a substance does not necessarily apply to nanoparticles – we MUST take the precautionary approach and avoid exposureSlide37
A means of containing or extracting hazardous fumes/vapours/aerosols away from the operator, to be safely discharged to the atmosphere

Personal Protective Equipment (PPE)Last resort not first line of defense
Lab Coats - must be worn in lab, remove before entering offices/clean areasHand - gloves - correct type for the work ProtectionEye/ face -
glasses, goggles, visors – depending Protection on hazardRespiratory - half masks, full masks, powered Protection hoods
- fit critical to protection
