INTENDED USE**
Give brief details and attach protocol/instructions
Acrylamide/bis-Acrylanmide – gel constituant to separate saccarides
Tris – buffer
Glycine – gel and buffer constituant
Ammonium persulfate – gel polymerization Activator
Temed – gel polymerisation catalyst.
Acetic Acid – to adjust pH
Ethylene Glycol – Constituant for running buffer
Bromophenol blue – colour marker to determine location of saccahrides
Phenol red – colour marker to determine location of saccharides

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?
Acrylamide/bis-Acrylanmide – Risk of harm due to splashes of liquid reagent to unprotected eyes and skin. Small
risk of inhalation. User may become sensitised with use.
Ammonium persulfate – Small risk of harm by inhalation. Risk of harm due to splashes to the unprotected skin
and eyes. User may become sensitised with use.
Temed – Corrosive – causes burns. Small risk of harm from inhalation. Risk of harm from splashes to unprotected
skin and eyes Flammable – vapour may trail towards sources of ignition.
Ethylene Glycol – Small risk of inhalation. Risk of harm from splashes to skin and eyes.
Acetic Acid – Corrosive risk by inhalation. Risk of burns due to splashes to unprotected skin and eyes.
Flammable – refrain from use by ignition sources.
Phenol red – Small risk of irritation by inhalation. Risk of harm due to splashes to unprotected skin and eyes.

CONCLUSIONS ABOUT RISKS
Is level of risk acceptable? Can risk be prevented or reduced by change of substance/procedure? Are control measures necessary?
Due to the nature of some of the chemicals listed in this assessment there is a small risk . But due to the small
amounts used and as long as measures laid out in section 8 are followed then the level of risk is acceptable. Non
of the chemicals used can be replaced with other “ less hazardous” reagents.

CONTROL MEASURES
Additional to Good Chemical Practice
Laminar flow hood recommended for manipulation of acrylamide powders.
Wear labcoat, safety glasses and chemical resistant gloves.
Be aware of and avoid sources of ignition.
9
INSTRUCTION/TRAINING
Specify course(s) and/or special arrangements.
One to one initial instruction
10
MONITORING
Performance of control measures,
Users of Respiratory sensitisers need to be registered with the HSU and Occupational Health PRIOR to
commencement of work, to enable assessment, monitoring of exposure and possible subsequent sensitisation.
Instruction given as to importance and application of control measures. Training given to aid recognition of initial
symptoms of sensitisation.
Personal exposure
Health Surveillance
Exposure to sensitisers - Lung function tests and health
review as instructed by Occupational Health. Records
kept of outcome courtesy of Occupational Health.
Exposure to sensitisers - Lung function tests and
health review as instructed by Occupational Health.

WASTE DISPOSAL PROCEDURE
See School Server for Approved Procedure Document on specific Chemical Waste Disposal.
Unused acrylamide solutions should be polymerised with APS and TEMED prior to disposal by incineration.
Used polymerised acrylamide gels should be disposed of by incineration.
Other reagents, ammounts listed within the protocol can be disposed of down the sink with copious amounts of
water.

EMERGENCY ACTION
TO CONTROL HAZARDS
To stabilize situation eg spread absorbant on liquid spill; eliminate sources of ignition, etc.
Small amounts of reagents listed within this protocol can be mopped up with absorbant material ( tissue ) .
Large spills of Acrylamide should be treated/mopped up with an adsorbant material,
TO PROTECT PERSONNEL
Evacuation, protection for personnel involved in clean-up, Special First Aid
Personal contact with listed reagents should be treated immediately by flushing with copious amounts of water
before seeking medical advice.
Respiratory difficulty should be treated immediately by moving to area of well ventilated clean air and seeking
medical advice if deemed necessary due to unresolvement of symptoms.
Contaminated clothing should be immediately removed.
Clean-up/decontamination
TO RENDER SITE OF EMERGENCY SAFE
Areas of spillage should be cleaned with a diltue decon solution
Acrylamide : Large spills warrant evacuation. Use of self-contained breathing apparatus, rubber boots and heavy
duty chemical resistant rubber gloves. Spill should be mopped up with absorbant material, swept up into a bag,
held for specialist waste disposal by Departmental Stores.
Ventilate area and wash spill with diltue decon solution after material pick up is complete.
Small spllls od acrylamide should be mopped up immediately, placed in a bag for specialist waste disposal. Area
cleaned with diulute decon solution.
