microlab safety theory

what is anthrax known as

bacillus anthracis

anthrax is what type of bacteria

gram +, rod shaped

anthrax is best known for

use in past bioterrorism attacks

anthrax spreads via

indirectly, spores

what capsule in anthrax makes it more difficult for immune system to fight

polyglutamic

what is a bio safety cabinet (BSC)

enclosed, ventilated laboratory workspace

BSC is also known as

microbiological safety cabinet (MSC)

BSC function

protects operator and environment from pathogenic materials and volatile chemicals

describe class I

open fronted, and air is drawn in entirely via the front opening

BCS class I function

protects the operator only

describe class II

open-fronted, with the air drawn in via the front, but it is drawn through a HEPA filter before being blown over the work

BCS class II function

protects both work and operator

describe class III

fully enclosed, with glove ports, and air is drawn into the cabinet via a HEPA filter. the operator is therefore segregated from the work by a solid barrier

BCS class III function

offers maximum protection to both used and the work

describe class I/III and function

protects both work and operator ; capable of running in either class I or Class III mode

describe negative air flow

isolation technique used to prevent air from flowing outside of room or lab

air flows from ___ to ___ pressure

high to low

pressure of a lab should be between

-30 Pa and -50 pa

what is worn to minimize exposure to serious workplace injuries

personal protection equipment (PPE)

describe fumigation

decontamination method, where affected area is filled with gas or vapor such as formaldehyde —> kills endospores, bacteria, viruses, fungi, algae, and protozoa
