* U.S. Biological Research Laboratories at Fort Detrick (1944)
A.G. Wedum, MD (Arnold)
26
one of the pioneers in developing biosafety measures after the Second World War
A.G. Wedum, MD (Arnold)
27
evaluated the risks of handling hazardous biological agents and developed practices, ventilated cabinets) equipment, and facility safeguards for their control
A.G. Wedum, MD (Arnold)
28
Wedum and microbiologist Morton Reitman, colleagues at Fort Detrick, analyzed multiple epidemiological studies of laboratory-based outbreaks.
1966
29
general principles for dealing with potential biohazards
Asilomar Conference in 1975
30
was suggested that containment should be an essential consideration in the experimental design and that the effectiveness of the containment should match the estimated risk.
Asilomar Conference in 1975
31
when is the use of mechanical pipettors to prevent laboratory-acquired infections
1907&1908
32
when does the pharmaceutical company (Pennsylvania) developed a ventilated cabinet to prevent infection from mycobacterium tuberculosis
1909
33
WHO eradicate smallpox (College of Physicians of Philadelphia 2014).
1967
34
designation of 4 levels of biosafety
mid-1970s-
35
CDC published the Classification of Etiological Agents on the Basis of Hazard
1976-
36
(introduced the concept of establishing ascending levels of containment associated with risks in handling groups of infectious microorganisms that present similar characteristics)
the Classification of Etiological Agents on the Basis of Hazard
37
(explained in detail the microbiological practices, equipment, and facility necessarily corresponding to four ascending levels of physical containment)

CONTAINMENT
46
PREVENTING THE RELEASE OF BIOLOGICAL AGENTS
▪ BIOCONTAINMENT:
47
(control hazard at source)
PRIMARY BARRIERS
48
PRIMARY CONTAINMENT EQUIPMENT
□ BSC □ ANIMAL ENCLOSURES □ SEALED CENTRIFUGE ROTORS
49
(structure surrounding primary barrier)
SECONDARY BARRIERS
50
SECODARY CONTAINMENT EQUIPMENT
HEPA FILTERS ▪ LIQUID EFFLUENT TREATMENT ▪ SEALED LABORATORY WALLS AND floor laminar flow wood
51
PRINCIPLES OF BIOSAFETY
▪ PRACTICE AND PROCEDURES CONSIDERATIONS ▪ SAFETY EQUIPMENT ▪ FACILITY DESIGN AND CONSTRUCTION ▪ INCREASING LEVELS OF PROTECTION
52
STANDARD MICROBIOLOGICAL PRACTICES
▪ MOST IMPORTANT CONCEPT / STRICT ADHERENCE ▪ AWARE OF POTENTIAL HAZARD ▪ TRAINED AND PROFICIENT IN TECHNIQUES
53
USED TO PROTECT FROM INFECTIOUS FLUIDS □ DON’T WEAR LAB COATS OUTSIDE OF THE LAB OR TAKE THEM HOME □ CUFFED SLEEVES CAN PROTECT THE WRISTS AND LOWER ARMS
▪ LAB COATS AND GOWNS
54
□ WEAR DISPOSABLE VINYL, SYNTHETIC OR N-DEX NITRILE GLOVES WHEN WORKING WITH BIOHAZARDOUS MATERIALS □ AVOID LATEX GLOVES (MAY CAUSE ALLERGIES) □ DO NOT REUSE GLOVES □ DO NOT WEAR GLOVES OUTSIDE OF THE LABORATORY □ WASH HANDS AFTER REMOVING GLOVES
gloves
55
□ PROTECT MUCOUS MEMBRANES AND PREVENT INGESTION WHENEVER THERE IS POTENTIAL FOR SPLASH TO EYES/FACE
▪ EYE AND FACE PROTECTION
56
OPEN TOED SHOES, SANDALS AND OTHER OPEN FOOTWEAR SHOULD BE PROHIBITED □ SHORTS AND OTHER GARMENTS THAT LEAVE SKIN UNPROTECTED ARE NOT APPROPRIATE
▪ FOOT/SKIN PROTECTION
57
□ TWO TYPES: AIR SUPPLYING AND AIR PURIFYING □ FULL FACE, HALF FACE, PAPR (POWERED AIR PURIFYING RESPIRATOR) RESPIRATORY PROTECTION □ N95 RESPIRATORS □ N100 RESPIRATORS
RESPIRATORY PROTECTION
58
BIOSAFETY CABINETS (BSC)
PROVIDE EFFECTIVE PRIMARY CONTAINMENT FOR WORK WITH INFECTIOUS MATERIAL OR TOXINS WHEN THEY ARE PROPERLY MAINTAINED AND USED IN CONJUNCTION WITH GOOD LABORATORY TECHNIQUES
59
Remove toxic chemicals (ducting/ductless) - NO HEPA filter = not for biohazard agents
FUME HOODS
60
Product protection (no personnel protection) - Not for biohazard agents or chemical fumes
LAMINAR FLOW CABINETS
61
CLASS I BSC: personnel and environment protection - CLASS II & III BSC: personnel, product and environment protection - HEPA filters (not for chemical vapors)
BIOSAFETY CABINETS
62
personnel and environment protection
CLASS I BSC:
63
personnel, product and environment protection
CLASS II & III BSC:
64
