Laboratory Hazards Flashcards
These are the three types of Laboratory Hazards.
- Physical
- Chemical
- Biological
This is a hazard that requires contact.
Physical Hazard
This is a hazard that involves reagents.
Chemical Hazard
This is a hazard that involved microorganisms and pathogens.
Biological Hazard
These are examples of physical hazards.
- Needles
- Broken Glass
- Sharps
These are examples of chemical hazards.
- Spills and Sprays
- Aspiration via Pipette
- Skin Absorption
These are examples of biological hazards.
- Bites of Animals
- Parasites
These are necessary precautions when handling needles, broken glass, and sharps.
- Do not recap needles
- Use durable sharp containers
- Use specific waste containers
- Never directly handle broken glass
These are safety precautions used in Biosafety Level 1 and 2 storage of chemical hazards.
- Spill Containment Cabinets
- Hazardous Waste Storage
- Flammable Liquid Storage
These are the 4 categories found in Material Safety Data Sheets.
- Flammabiity (Red)
- Reactivity (Yellow)
- Health (Blue)
- White (PPE)
These are hazards that makes use of aerosols and droplets as their main sources of contamination.
Biological Hazards
The most frequently reported infectious agent in laboratories in the US during 1979 to 1999
Mycobacterium tuberculosis
This is an example of a single-source with multi-laboratory infections.
Brucellosis; Centrifugation
These are the main contamination routes.
- Inhalation
- Skin
- Ingestion
- Occular Vision
These are examples of chemicals that can contaminate via skin absorption.
- Cylin
- Ogranophosphate
- Cyanide (Most Deadly)
This is the element that blocks radioactive chemicals.
Lead (Pb)
The difference between inserts and manuals.
Inserts are paperwork. Manuals are instructions.
These are the PPE for BSL 1 and 2.
- Laboratory Coat
- Gloves
- Goggles or Face Shield
- Masks
- Hearing Protection
This is a PPE that is 1 time use and should always be worn in a laboratory.
Gloves
This is a PPE that is used to protect the mucous membranes from air droplets.
Googles and Face Shields
This is a PPE that reduces the amount of pathogens that enters the respirtory system.
Masks
A procedure that tests which respirator is suited for the shape of your face and mouth.
Fit Testing
This is a PPE that is a mandatory part of a laboratory outfit and requires inflammable fabric. BSL 3 must require this PPE to be disposable.
Lab Gown
This is a type of spills that are manageable and can be cleaned by a regular person.
Minor Spills
This is a type of spill that requires help from outside of a laboratory group.
Major Spill
These are the materials that can be used to clean chemical spills.
- Baking Soda
- Polypropylene Pads
- Diatomaceous Earth (Parasites)
This is a type of spill that involved live organisms or bodily fluid.
Biological Spills
This is the duration in which cleaning solutions must remain in biological spills.
at least 20 minutes
These are the concentraion used in disinfecting surfaces.
1:10 and 1:50
These are the two classification of fire.
- Small Fire
- Large Fire
These are the classifications of fire extinguishers.
- A (Wood or Paper)
- B (Organic Material)
- C (Electrical)
- D (Metal)
- K (Greese)
This is the meaning of PASS.
Pull, Aim, Squeeze, Sweep
This is what to avoid when designing a laboratory or workflow.
Common Pathways
These are the factors wherein safety is depenent on.
- Supervisor
- Safety Manual and SOP
- Trained Personnel
- Risk Assessment
- Lab Design
This is the meaning of SOP.
Standard Operating Procedure
