INTENDED USE**
Give brief details and attach protocol/instructions
Polymerisation of polyacrylamide gels mostly containing SDS and sometimes up to 1.5M urea using 0.1%
TEMED and >0.1% ammonium persulphate
Samples to be prepared in buffer containing 10% glycerol, 100mM dithiothreitol and 0.1% bromophenol blue and
are often boiled using a PCR thermocycler.
Acetic acid (10%) and methanol (30%) to be used in fixing and de/staining. Stain contains 0.1% coomassie blue
6
RISKS to HEALTH and SAFETY from INTENDED USE
From personal exposure or hazardous reactions. Refer to OELs, flash points, etc., as appropriate. Are pregnant women, breast-feeding
mothers especially at risk?
Acetic acid: Flash point 40C
Methanol: Flash point 11C
TEMED: Flash point 10C
7
CONCLUSIONS ABOUT RISKS
Is level of risk acceptable? Can risk be prevented or reduced by change of substance/procedure? Are control measures necessary?
Acceptable level of risk. Cannot substitute chemicals. See below for control measures
8
CONTROL MEASURES
Additional to Good Chemical Practice
Use Nitrile gloves and eye protection for handling acrylamide-containing solutions.
Wear face mask for dispensing SDS powder
Solutions of Acrylamide will be purchased in order to decrease the risk of inhalation
9
INSTRUCTION/TRAINING
Specify course(s) and/or special arrangements.
New staff/students to be trained by postdoctoral fellows where applicable.
10
MONITORING
Performance of control measures,
Personal exposure
Health Surveillance
Personal exposure should not occur if the control
measures are observed.
As Personal exposure.
11
WASTE DISPOSAL PROCEDURE
See School Server for Approved Procedure Document on specific Chemical Waste Disposal.
Polyacrylamide gels will be disposed of as solid waste
Waste acrylamide solutions will be polymerized and disposed of via solid waste
Destain will be disposed of via non-halogenated solvent waste route.
12
REVIEW
Enter the date or circumstances for review of assessment (maximum review interval 5 years)
Update names of users as changes occur
13
EMERGENCY ACTION
TO CONTROL HAZARDS
To stabilize situation eg spread absorbant on liquid spill; eliminate sources of ignition, etc.
Use absorbent on spills of buffers, acrylamide and stain-destain solutions. Dispose absorbent from acrylamide
spills as Special Waste and thoroughly wash affected area. Shut off sources of ignition where glacial acetic acid
and methanol are involved.
TO PROTECT PERSONNEL
Evacuation, protection for personnel involved in clean-up, Special First Aid
Inform other laboratory members to avoid the affected area during cleaning
Those involved in cleaning should wear appropriate gloves (see above)
TO RENDER SITE OF EMERGENCY SAFE
See control hazards and personnel protection
