SOME GENERAL RISK ASSESSMENT IDEAS IN Science-CHEMISTRY

see also page on Gas Preparation and Collection Methods in chemistry

and further Chemistry - Rates of reaction investigation ideas

This not some definitive list and is more appropriate to chemistry, but it should give you some idea how to think on risk assessment for some coursework project or assignment

'Area' of potential risk for either student or teacher Hazcard information essential reading * particular pairs of linked risks
(1) EQUIPMENT and its SAFE USE
holding material in tongs or test tube holder safely
danger of test tube cracking on heating
over-heating danger (bunsen position, flame size etc.)
need for sand tray e.g. in oil distillation demonstration
danger of test tubes falling out of rack
water near lab pack e.g. electrolysis experiments
putting stoppers back on bottles
* ensure safe working space around you
* standing to do experiments, always?
only take the quantities of chemicals instructed or required
connecting bung in test tubes or flasks
setting up and filling a burette
any of the chemicals flammable or oxidising?
setting up equipment safely eg stand and clamp correct and stable
need for fume cupboard?
(2) GENERAL HEALTH and SAFETY
* harmful gas/vapour e.g. alkanes, acid expts, chlorine
* asthma suffers - increased risk of irritation
inappropriate use of, or play with, spills/splints etc.
inappropriate use of paper to light a bunsen
* irritating/harmful chemicals on hands, face etc. action
* need for plastic gloves? hazard or skin allergy risk?
safety glasses (always class practical, demonstration?)
need for safety screen in demonstration
how close can the pupils be to the safety screen?
(3) ACCIDENT ACTION & TIDY UP
clearing away chemicals and equipment
action required for anticipated accidents
