biological agents (germs). lead,
asbestos
radioactive substances Hazardous substances COSHH Doesn't covers these have their own specific regulations. Fume laden air Wood workers Quarry workers Lung diseases Benzine in Crude oil Oil workers Leukemia Flammable liquids Hazards Gas station Who COSHH applies to 1. If an organization , company , workplace has employees dealing with hazardous substances

is the necessary obligation by the authority if not its termed as a crime . Efferent Lymphoid vessel Afferent Lymphoid vessel Primary lymphoid follicle Secondary lymphoid follicle Germinal Center Capsule Artery Vein Marginal sinus Medulary sinus Medulary chords All containers , bottles , should be properly labeled with the standard COSSH signs COSHH In laboratories The laboratory consists of many hazardous substances including
chemicals
biologicals
sharps
animals
electrical equipment
Infectious organisms Chemicals Infectious organisms An Organism unlikely to cause human disease . An Organism which causes severe human disease
serious hazard to employees
likely to spread to the community and there is usually no effective
prophylaxis or effective treatment available. Hazard group 4 An Organism which causes severe human disease
risk of spreading to the communityusually effective prophylaxis or effective treatment available. Hazard group 3
An Organism which can cause human disease and may be a hazard
to employees
unlikely to spread to the community
treatments available . Hazard group 2 Hazard group 1 Permitted in teaching and research laboratories eg S. bovis ,Proteus mirabilis ,S. mutans, S. pyogenes only be used in an approved laboratory
the radioactive Hazards should be handled properly with proper supervision
the employees must me informed and trained All pharmaceuticals should be kept in secure conditions.
With proper storage facility
All poisons must be stored in a locked cabinet.
Maintained with proper care Radioactive hazards Poisons Pharmaceuticals Specimen disposal and hazardous waste Laboratory and hospitals contains many specimens which are harmful
therefore proper disposal protocols should be practiced hazards related to specimen hazards related to specimen Syringes, needles, and I.V. sets
Surgical blades
Dressings from draining wounds
Any material which comes in contact with a draining wound
Human tissue/specimen not sent for pathological evaluation
Blood elements and secretions
Disposable equipment
Any other material presenting a threat of infection infectious Hazardous Basic regulations of the act o Proper ventilation
The premisses should be clean and properly maintained
Proper seating should be installed

Minimal temperature 60 F
Drinking water should be available
First Aid kit should be installed with adequate items : employee should be able to use it when needed
adequete spacing should be provided for each person and storage facilities
Natural or adequate artificial lighting should be provided Quality control and quality assurance Quality : 'The totality of features and characteristics of a product or a service , and the ability to satisfy the consumer needs . ' Quality management : assembly and management of all works related to maintaining the quality of the product or service provided Quality management Quality Control Quality Assurance Quality in the laboratory Accurate results
Results within a short period of time
Patient and physician satisfaction
Maintaining patient history
Minimized errors
Will reduce wastage
Increase the net profit with best services
Will notify exactly the errors are made there for training can be done properly Quality Control quality control in the laboratory should be implemented to maintain routine technical activities to measure and control the activities . Main functions of QC: 1. Mundane accuracy checks
2. Identification of errors
3. Document proper record system Quality Control Protocol First line control Second line control Third line control Fourth line control Instrument performance check Checking calibration and standardization Batch control Overall check Quality assurance Quality assuarance is normally done by a person who is not directly involved in the compilation and development process the protocol is a planed system of reviews The personal should
make sure that the services and the products meet the quality objectives .
measure the error levels
identify where the errors are made ISO (International Organization for Standardization) ISO is a world wide federation for standardization
helps in making the laboratory more efficient and effective SLSI (Sri lanka Standards institution ) Sri Lanka Standards Institution (SLSI) is the National Standards Body of Sri Lanka Caerphilly Business Park Caerphilly CF83 3GG
