Safety Regulations In The Chemical Laboratory

1. Safety Regulations In The Chemical Laboratory Bryan McGowan Safety Officer School of Chemistry Room: 252 Ext: 4-4027 Mobile: 0431 688 447 Email: bmc@unimelb.edu.au Sioe See Volaric Deputy Safety Officer Room: 380 Ext: 4-6472 Email:sioe@unimelb.edu.au Christian Rantzau Bio 21 EHS Coordinator Ext: 4-2207 Mobile: 0401 171 097 Email: Rantzau@unimelb.edu.au School of Chemistry, Jan 2014

2. Personal Protective Equipment • Lab coat • Safety Glasses/Goggles • Closed shoes • Gloves: Latex, Nitrile, Neoprene, Barrier, PVC, PVA, Cotton, Leather Welding, etc. • Face Shield • Other PPE as required for the task

3. Glove Safety • Do: • Ensure you use the correct glove for the chemical-consult MSDS • Replace gloves IMMEDIATELY after contamination • Do Not: • Re-use gloves • Touch common surfaces (door handles) with gloves • Wear gloves or lab coats outside of the lab • Watch out for defective gloves (check expiration date)

4. SHOES • Examples of suitable footwear • Examples of unsuitable footwear

5. Personal Protective Equipment The last line of defence. PPE use is mandatory. PPE Maintenance & Inspection: • Check PPE on a regular basis—send lab coats for cleaning • Throw out PPE when it is worn/damaged • Replace with new ones conforming to Australian Standards

6. Building Evacuations • If the alarm sounds, safely shutdown all experiments (gases, heat, reactions that require monitoring). • A floor warden wearing a yellow hard hat will ensure areas are clear and assist with an orderly evacuation (do not wait to be told). • KNOW THE LOCATION OF: • Various exit pathways • First Aid kits • Safety Showers / Eye Wash Stations • Spill kits—every lab must have one • Fire extinguishers / fire blankets • Emergency Assembly Area

7. Emergency Assembly Area MacFarland Court

8. Emergency Information • Once outside, take direction from the Wardens and proceed to the assembly point – MacFarland Court (grassy area next to Chemistry West). • Stay out of the building until you are told by the Building Emergency Controller (BEC) that you are allowed to re-enter the building. • If you have an incident in your lab, please inform the Safety Officer ASAP. No incident scene should be cleaned up without permission from the Safety Officer. • If there is a fire and the fire alarm has not sounded, activate the closest red break-glass alarm – this will contact the fire brigade and evacuate the building. Only fight small fires. • Emergency contacts are listed in the Safety Manual and throughout the building.

9. Material Safety Data Sheets Before using a chemical for the first time, you must read the MSDS. An MSDS contains information you need to safely use, store, and dispose of the chemical and what to do in the event of a spill, leak or exposure. Australian MSDSs have 16 sections. • Identification: UN number, DG class, Poisons schedule, Hazard Ratings and statements, etc. • Physical data: Flashpoint, auto-ignition temperatures • Emergency data: Spills, health effects, first aid • Storage and use: Incompatibilities, disposal considerations. • MSDSs can be accessed in ChemWatchGoldFFX at: http://safety.unimelb.edu.au/topics/chemical/chemwatch/

18. Chemical Hazard Risk Assessment Available in Green lab books from Chemistry Store Must be added to other lab books Must be signed off by your supervisor before the work If this form is not appropriate for the experiment use a generic risk assessment form.

21. Risk Control Hierarchy Most Preferred Least Preferred • Eliminate (design change) • Substitute (safer chemical) • Isolate (barriers / enclosure) • Engineering controls (fume hood) • Administrative controls (rules) • Personal Protective Equipment

22. Faulty / Broken Equipment Affix tag in a visible location and tell your supervisor

23. DO NOT POUR CHEMICALS DOWN SINKS! Use the appropriate waste container (Water Soluble, Water Insoluble, Chlorinated etc.) Glass/plastic bottles Clean glass only in glass bins behind the building – choose recycling or landfill. Remove chemical residue Remove/deface chemical label incl. hazard diamond Residue-free chemical containers are recyclable-bins outside Pyrex glass (lab glassware), Pasteur pipettes, slides are not recyclable. Waste Recycling In green/yellow bins Contents as indicated Printer cartridges Batteries (safe disposal)

24. Housekeeping • Keep benches tidy & clutter free • Corridors, passages, exits must remain clear • Seal all chemical and waste containers • Label chemical containers clearly (full chemical name) • Do not store chemical containers on the floor • Liquid chemicals must be in spill trays • Keep the laboratory floor dry at all times. Clean up spills. • Food and drink must never be taken into laboratories • Ensure sinks are clear of rubbish, debris and any obstructions • Beware of broken glass – clean up only with dust pan and brush to prevent glass cuts

25. Additional Requirements • All water connections must have hose clamps installed. • All unattended hotplates must have a secondary temperature control method. • Passengers must not travel in a lift with gas cylinders or liquid nitrogen.

26. Supervision / After hours work • Hons/Masters/PhD students/staff must not carry out experiments alone in the lab. • Working after hours: 6pm – 7:45am, weekends, public holidays: • Swipe card access, East Wing entrance or bio21 foyer • Fill in After-Hours Register • No hazardous operations after hours • Use a buddy system • Do not loan your keys/card to anyone. Report lost keys/card. • No parties, no alcohol consumption!

33. Other Safety Information • Some entry/exit points to the building will be blocked at various times. Learn your way around using different entry/exit points. • Report unsafe areas/situations to the Safety Officer. • Smoke Free Campus – designated spots only • Read Chem News every Friday for safety updates. Let us know if you are not receiving it.
