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
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)
SHOES Examples of suitable footwear
Examples of unsuitable footwear
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
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
Emergency Assembly Area
MacFarland Court
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.
Material Safety Data SheetsBefore 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 ChemWatch GoldFFX at:

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.

Faulty / Broken EquipmentAffix tag in a visible location and tell your
supervisor
WasteDO 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.
Recycling In green/yellow bins Contents as indicated Printer cartridges Batteries (safe disposal)
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
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.
Supervision / After hours work
Hons/Masters/PhD students/staff must not carry out experiments alone in the lab.
Working after hours: 6 pm – 7:45 am, 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!
Gas Alarm strobe & siren
Gas Alarm Panel – data display

Lab Inspections
Full lab inspection: Every 3 months, Bio21
Every 6 months, Chem
Emergency eye washes: Weekly Safety Showers: Every 4 weeks
Specific Safety Inductions
Resonance Lab, Room 283 NMR, Mass Spectrometry, EPR Decanting liquid nitrogen
X-Ray Diffractometer Lasers (plus eye exam required) Solvent Decanting
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.
