INTENDED USE**
Give brief details and attach protocol/instructions
Antibiotics will be added to culture media at low (g/ml) in order to select for recombinant bacteria.
Detergents will be used to solubilise membrane extracts.
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?
Kanamycin sulphate, gentamycin sulphate, streptomycin sulphate, EMB & Tyloxapol may all be harmful to unborn
children and should be avoided by pregnant workers.
Materials that cause burns, i.e. Zinc salts and PMSF are to be used in small amounts (mg) and therefore wearing
of latex gloves and a laboratory coat should provide adequate protection.
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
Wear latex gloves for handling all listed chemicals.
Face masks should be worn by those who suspect may be pregnant while dispensing Kanamycin sulphate,
gentamycin sulphate, streptomycin sulphate & EMB
Tyloxapol boils at 68C so should be sterilised by filtration rather than in an autoclave.
Materials that cause burns, i.e. Zinc salts and PMSF are to be used in small amounts (mg) and therefore wearing
of latex gloves and a laboratory coat should provide adequate protection.
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.
Spent culture medium and other contaminated fluids are to be autoclaved and disposed of via normal 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.
Disinfect spillages of biological materials with Microsol3. Allow at least 5 min contact time for disinfection and
then clear up spill using absorbent material. Autoclave absorbents and dispose of as solid waste. Wash area
thoroughly. Non-contaminated fluids should be absorbed and the area washed thoroughly.
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 latex gloves.
Face masks should be worn when clearing up gram-scale spills of Zn2+ salt and antibiotics powders. Spills
should be contained using absorbent granules and then placed in a closed container and arrange for its disposal.
