Presentation Transcript

Slide 1: 

Laboratory Safety and Safety Ethics A.K. CHHABRA Professor Plant Breeding DISCLAIMER: Copyright of some of the figures used from internet and different web sites is duly acknowledged. The copyright stands with its original developer. The information has been gathered here for educational purpose and not for any kind of commercial purpose.

Slide 2: 

Safety in Research Laboratory Agricultural science is basically an applied science; so to conduct research we need laboratories. What is laboratory? It is a room or building used for scientific research, experiments or testing etc.

Slide 3: 

Safety in Research Laboratory Features of a Good Laboratory

Slide 4: 

Safety in Research Laboratory Laboratory Design and Safety Laboratory varies with its kind as it may be of Teaching or Research Laboratory, it may also be Physics, Chemistry, Botany or Zoology or it may be any special purpose laboratory. Requirements and designs of laboratory vary with the application for which the laboratory is to be utilized. Thus before we go for the establishment of any laboratory we should go for certain planning in our mind.

Slide 5: 

Safety in Research Laboratory Objectives for laboratory safety planning: Developing Workable Safety Statement “Safety requires focusing attention on the immediate work environment and modifying behavior and facility to protect personnel and property.”.

Slide 6: 

Safety in Research Laboratory Defining the Technical Objective of the New Laboratory Laboratory objective may be one of the following: General-purpose laboratories. Special-purpose laboratories Special occupancy laboratories Teaching or Research Laboratory

Slide 7: 

Safety in Research Laboratory General-purpose laboratories are those in which a variety of operations are carried out, usually in conventional apparatus and glassware, employing a number of the usual small laboratory instruments and using relatively small amounts of chemicals. Physics, Chemistry Labs for UG students

Slide 8: 

Safety in Research Laboratory Special-purpose laboratories are those intended for continuing use in one operation or manner involving definite or specific hazards, which require less stringent fire protection, electrical or emergency features. Biology labs for PG students

Slide 9: 

Safety in Research Laboratory Special occupancy laboratories may involve high-level hazards such as high pressure equipment, carcinogens or radioactive substances, flammable liquids or gases, high energy materials or biological health hazards. RIL, Electron Microscopy Lab, Tissue Culture Lab etc.

Slide 10: 

Safety in Research Laboratory Identifying Techniques for Determining User Safety Needs – Engineering associations and similar organizations have issued invaluable literature on laboratory safety concepts. Laboratory personnel who have precious experience in a similar situation should be formed into a subcommittee to share information with management. Experienced Lab technician

Slide 11: 

Safety in Research Laboratory Ranking Safety Requirements for Laboratory Facility – In the view of laboratory managers, the heating, ventilation and air conditioning system (HAVC) is the most important requirement for laboratory safety. FOLLOWING SAFETY MEASURES ARE REQUIRED: Laboratory exhaust ventilation Fire safety Emergency response Chemical handling

Slide 12: 

Safety in Research Laboratory Improper design, construction or layout. Protective devices not provided or proper equipments and tools are not provided. Failure to use protective devices provided and proper equipments and tools not provided. Lack of knowledge or improper mental attitude. Laboratory outside the organization. Use of devices with unknown defects. Bad physical conditions or handicap. Failure to follow instruction or rules. Failure of person incharge to give adequate instructions or inspections. Failure of person incharge to properly plan or conduct the activity. Basic Causes of Accident in Laboratory During Work:

Slide 13: 

Safety in Research Laboratory Requirement of national level organization which will coordinate and guide the research activities in research laboratory. The primary objective of such departments is to provide the guidance to the organizations and institution and not acts as policing agent. The member of the organization must be aware of technological advances so that they may provide best possible advices and trainings. Second major responsibility of such organization is to monitor the activities and management research laboratories in different institutions. The organization must be provided to with the enforcement authority to properly monitor compliance/compulsory adoption of the rules formulated by organization.

Slide 14: 

Safety in Research Laboratory Organization for safety in Laboratories: Laboratory director, Dean Supervisor or senior faculty Employee, junior faculty members and student V.C/ President of University Cooperated or university safety department Staff and university safety committee Safety engineer or coordinator Local safety committee

Slide 15: 

Safety in Research Laboratory Laboratory Hazards Fire Hazards Chemical and Toxicity Hazards Radiation Hazards Electrical Hazards Biological Hazards

Slide 16: 

Safety in Research Laboratory Fire Hazards: During working periods lab research worker are liable to receive burns caused by burners that are blown back, hot glass, non-luminous flames, ignition of inflammable solvents or clothing’s catching alight. Combustible materials are frequently used labs involving fire risks against which worker must protect himself as well as lab. Unprotected chemicals may provide fuel to increase the size and extent of the damage of a small fire. Research notes, theses material, unique chemicals, financial and academic records and above all a precious life; are more difficult to reproduce than a building and equipments.

Slide 17: 

Safety in Research Laboratory Prevention: An appropriate extinguishing system should be installed. Accumulation of materials in lockers and corners, near machinery, steam pipes and furnaces and stoves should be avoided. Fire protected storage should be there for records chemicals etc. Rubber gas connected tubes must be inspected regularly to minimize the chances of slipping and splitting of a tube. Regular inspection of all installations, apparatus and wiring is necessary to ensure that they are safe and secure.

Safety in Research Laboratory Workplace in isotope laboratory Waste container for "short-life" radioactive waste. …….. …….. …….. P32

Slide 26: 

plu·to·ni·um (plū-tō'nē-əm)    n. (Symbol Pu) A naturally radioactive, silvery, metallic transuranic element, occurring in uranium ores and produced artificially by neutron bombardment of uranium. Its longest-lived isotope is Pu 244 with a half-life of 76 million years. It is a radiological poison, specifically absorbed by bone marrow, and is used, especially the highly fissionable isotope Pu 239, as a reactor fuel and in nuclear weapons. Atomic number 94; melting point 640°C; boiling point 3,235°C; specific gravity 19.84; valence 3, 4, 5, 6. Safety in Research Laboratory
