HEALTH & SAFETY IN THE SCIENCE LAB: RISK ASSESSMENT For use in conjunction with the Lab Safety Manual. Activity Associated Hazards/Risks Receipt of chemicals into the laboratory Unknown chemical properties and safe handling/storage requirements Handling and managing toxic/dangerous chemicals Chemicals that require special permits, licensing requirements and so on Inadequate and/or unavailable storage facilities Chemicals delivered to wrong area or an area not appropriately set up for receipt of chemicals Temporary storage are inappropriate location/facilities Damaged packaging: physical exposure fume spills and leaks Risk Rating Medium Who/What might be at risk Responsible Person Controls Additional Controls Required Students Teachers Lab Technician Maintenance Visitors Lab Technician Health & Safety Officer Maintenance Team Risk assessment of area where chemicals are delivered Chemical risk assessments Rationalizing chemical supplies to ensure: o ordering minimum quantities o compatibility of chemicals o adequate storage facilities and space available o all required signage and PPE is available Substituting less toxic chemicals where possible Use of purpose built chemical cupboards Use personal protective equipment as described in the MSDS Emergency procedures in place First aid kits Training provided for maintenance team/personnel who receive chemical deliveries Local induction and emergency training Spill kits Trained first aiders Periodic inspection of firefighting equipment Residual Risk Rating Low Activity Associated Hazards/Risks Storage of chemicals Incompatible chemicals stored together leading to fire and or explosion Damaged, removed or incorrect labels Damaged containers Chemicals stored in inappropriate areas. For example corrosive chemicals stored under a sink and not a purpose built corrosives locker Toxic fumes Chemical spills and leaks Manual handling hazards associated with large heavy containers of chemical Time sensitive chemicals – properties of chemicals alter, can become unstable Risk Rating Medium Who/What might be at risk Responsible Person Controls Additional Controls Required Teachers Lab Technician Maintenance Lab Technician Health & Safety Officer Risk assessments to determine appropriate storage arrangements and packaging requirements Use of chemical lockers: o corrosives locker o poisons locker Where ever possible chemicals stored in their original containers/packaging. Where this is not appropriate a risk assessment is undertaken to ensure correct packaging and labeling Signage where required Time sensitive chemicals dated and monitored through scheduled workplace inspections Use personal protective equipment described in the SDS Training for workers responsible for storing and accessing chemicals Access to chemical storage restricted to authorized personnel only First aid kits Training provided for maintenance team/personnel who receive chemical deliveries Local induction and emergency training Spill kits Trained first aiders Periodic inspection of fire equipment Residual Risk Rating Low Activity Associated Hazards/Risks Using and handling chemicals Incompatible chemicals mixed together: fire explosion release of toxic fumes Creating unknown new chemicals Damaged, removed or incorrect labels Chemicals used in inappropriate containers Chemicals used in inappropriate areas Toxic fumes and leakage from chemical experiments Fire and explosion during decanting Physical contact with a chemical; poisoning Manual handling hazards associated with large heavy containers of chemical Manual handling injuries from moving and setting up gas cylinders Risk Rating Extreme Who/What might be at risk Responsible Person Controls Additional Controls Required Students Teachers Lab Technician Maintenance Visitors Lab Technician Science Teachers Risk assessments to determine chemical properties and appropriate handling arrangements - Teachers Training provided for Teachers/maintenance team/personnel Local induction and emergency training Spill kits Trained first aiders Periodic inspection of fire equipment Maintenance documents installed for fume cupboard, eye wash stations, housekeeping should be aware of activities in which flammable gases such as hydrogen may be produced.

Acid Always add acid to water Clear up any spillages immediately according to COSHH guidelines. Ensure that all disposable pipettes that have come into contact with the acid are rinsed immediately after use and before disposal.

Lab Technician trained to handle/dispose microbes recommended Activity Associated Hazards/Risks Risk Rating Who/What might be at risk Responsible Person Controls Additional Controls Required Residual Risk Rating Cultures of microorganisms should be grown at or near room temperature. Do not grow cultures at 37 C Petri dishes containing cultures should be autoclaved before disposal. Do not pipette by mouth - use a pipette bulb or other pipetting device.
