1
LAMINAR FLOW HOODS USE COMPLEX FILTERS TO REMOVE MICROORGANISMS; ASEPTIC ENVIRONMENT USED FOR:
ARTIFICIAL INSEMINATION.
PLANT TISSUE CULTURE.
BIOREMEDIATION.
SEMEN EVALUATION.
2
WHEN DILUTING ACIDS IT'S IMPORTANT TO SLOWLY ADD THE ACID INTO COOL WATER AS:
MANY CONCENTRATED ACIDS ARE NOT WATER SOLUBLE
MANY CONCENTRATED ACIDS CAN FLASH BOIL WATER, SPATTERING IT
ALL ACIDS ARE WATER SOLUBLE
MANY CONCENTRATED ACIDS CAN REACT VIOLENTLY, LEAVING FUMES
3
WHAT IS THE LEAST IMPORTANT REASON FOR USING SPECIALIZED CHEMICAL CABINET?
PREVENT LEAKS.
CLOSE EASILY AND SEAL TIGHTLY.
STORE REPORT FORMS.
CONTAIN AND SMOTHER FIRES.
4
PRIOR TO USING CHEMICALS IN AG LAB EXPERIMENTS, INDIVIDUALS MUST HAVE READ KNOW THE LOCATION OF
UNITED STATES DEPARTMENT OF AGRICULTURE ANNUAL REPORT
MANUFACTURERS PROMOTION SHEETS (MPS)
ENVIRONMENTAL PROTECTION AGENCY WARNING (EPA-W)
MATERIAL SAFETY DATA SHEET (MSDS) AND CONTAINER LABEL
5
KNOWING THE CONCENTRATION OF CHEMICALS USED IN LABORATORY EXPERIMENTS IS CRITICAL AS:
MORE CONCENTRATED CHEMICALS WILL SPEED UP RESULTS
LESS CONCENTRATED CHEMICALS COULD LEAD TO LAB FAILURE
MORE CONCENTRATED CHEMICALS WILL ACHIEVE BETTER RESULTS
PURE CHEMICALS ACHIEVE MORE EFFECTIVE RESULTS
6
THE STORAGE OF ALL EQUIPMENT AND MATERIALS NEEDED FOR CONDUCTING A EXPERIMENT ON THE WORKSPACE
ENABLES RESEARCHERS TO WORK MORE QUICKLY AND EFFICIENTLY
IS A SAFETY HAZARD AS THESE THINGS CLUTTER THE WORKSPACE
IS WASTED EFFORT
IS HELPFUL FOR RESEARCHERS
7
WHAT IS NOT AN EFFECTIVE METHOD FOR STERILIZATION OF LABORATORY EQUIPMENT AND INSTRUMENTS?
DIPPING IN A 70% ETHANOL SOLUTION.
ANTIBACTERIAL SOAP.
TREATMENT IN AN AUTOCLAVE.
CONTACT WITH THE OPEN FLAME OF A ALCOHOL BURNER.
8
INFORMATION ON EVERY CHEMICAL AND SOLUTION IN A LABORATORY IS MOST LIKELY FOUND IN:
LAB CHEMICAL RECORD SHEETS.
MATERIAL SAFETY DATA SHEETS.
MATERIAL CERTIFICATION RECORDS.
HAZARDOUS MATERIAL CARE SHEETS.
9
TO SAFELY EXTINGUISH FIRES CAUSED MY VOLATILE CHEMICALS AND FLAMMABLE LIQUIDS, USE A:
CLASS B OR CLASS D FIRE EXTINGUISHERS.
LARGE AMOUNTS OF WATER.
A FIRE BLANKET.
CLASS A FIRE EXTINGUISHERS.
10
PREVENT MIXING OF CHEMICALS DURING DISPOSAL IN A SINK AS SOME CHEMICALS IN AGRICULTURE LABS:
OCCUR IN GRANULAR OR POWDERED FORM.
REACT VIOLENTLY WHEN COMBINED.
PRODUCE NOXIOUS FUMES.
CAN EAT THROUGH DRAIN PIPES.
11
IF A CHEMICAL IS CONSUMED DURING A LABORATORY PROCESS, A INSTRUCTOR SHOULD CONSULT THE:
LABORATORY SAFETY POSTERS.
THE INTERNET.
TECHNICAL SUPPORT FROM THE CHEMICAL COMPANY.
MATERIAL SAFETY DATA SHEETS FOR THE CHEMICAL.
12
ALL GLASSWARE, CHEMICAL VESSELS, AND CONTAINERS IN A LAB SHOULD BE:
DISPOSED OF IMMEDIATELY AFTER USE
ORGANIZED BY COLOR
UNLABELED
PROPERLY LABELED
13
CONTROLLED BIOLOGICAL MATERIALS SHOULD BE AUTOCLAVED AFTER USE TO ENSURE:
THE MATERIALS WILL SURVIVE RELEASE INTO THE ENVIRONMENT.
THE DESTRUCTION OF ANY REMAINING LIVING ORGANISMS.
THE VIABILITY OF MATERIALS USED IN RESEARCH.
RESEARCHERS WILL NOT ACCIDENTALLY USE THE SAME MATERIALS.
14
WHEN USING ASEPTIC PROCEDURE IN A LAB, INSTRUMENTS SHOULD BE DISINFECTED:
AT THE BEGINNING OF THE LAB.
AT THE END OF THE DAY.
BEFORE EACH NEW STEP IN THE LAB.
AFTER THE LAB.
15
THOUGH LABORATORIES SHOULD BE WELL VENTILATED, PUNGENT AND NOXIOUS CHEMICALS SHOULD BE USED:
FOR SHORT PERIODS OF TIME.
NEAR A WINDOW.
UNDER FUNCTIONING FUME HOODS.
16
ALL MUST KNOW THE HAZARDS PRESENTED BY A CHEMICAL IN RESEARCH STUDIES. THIS INFORMATION IS:
THE WEBSITES OF CHEMICAL PRODUCERS AND SELLERS
IN THE DESK OF THE LABORATORY MANAGER
IN THE MANUFACTURERS PROMOTION SHEETS
IN THE MATERIAL SAFETY DATA SHEET OF THE CHEMICAL
17
HOLLY REPORTS A DANGEROUS SAFETY CONDITION IN THE BIOTECH LAB. SHE NOTES THE PROBLEM AS:
THE PLACEMENT OF GLASSWARE IN A RACK TO DRY AFTER CLEANING
CHEMICAL MATERIALS WITH MISSING/DAMAGED LABELS
THE PLACEMENT OF FLAMMABLE CHEMICALS IN A LOCKED CABINET
THE PLACEMENT OF GLASSWARE LOCATED IN CABINETS AT EYE LEVEL
18
IF MAINTAINING ASEPTIC CONDITIONS IN A LAB EXPERIMENT, CONTAMINATION OF MATERIALS IS PREVENTED:
WASHING HANDS AND WRISTS WITH ANTIBACTERIAL SOAP
BY HANDLING MATERIAL WITHOUT GLOVES
TAKING A BREAK WITHOUT WASHING HANDS
BY PLACING MATERIAL ON THE FRONT EDGE OF THE WORK AREA
19
ENZYMES FOUND IN FOOD ARE GENERALLY SAFE TO HANDLE. SAFETY PRECAUTIONS SHOULD BE TAKEN WHEN:
THEY ARE IN CONCENTRATED FORM
THEY ARE IN LIQUID FORM
THEY ARE IN SOLID FORM
THEY ARE IN DILUTED FORM
20
WHAT TYPE OF CHEMICAL SPILL IS TREATED BY APPLYING A MILDLY ALKALINE CHEMICAL TO THE AREA?
BASE.
ORGANIC.
INORGANIC.
ACID.
21
THE USE OF RESTRICTED BIO MATERIALS IN AGRICULTURAL LABS REQUIRES:
PROOF THAT ORGANISMS WILL ONLY BE USED IN BIOTECHNOLOGY
THAT ALL ORGANISMS TO BE AUTOCLAVED PRIOR TO USE
THE PRESENCE OF PREDATOR ORGANISMS
SPECIAL PERMITS FROM THE FEDERAL GOVERNMENT
22
TO MEASURE THE MASS OF A LIVING ORGANISM THE MOST ACCURATELY AND EFFECTIVELY, USE A:
GRADUATED CYLINDER.
SINGLE BEAM BALANCE.
DIGITAL SCALE.
TRIPLE BEAM BALANCE.
23
WHEN POURING CHEMICALS/SOLUTIONS INTO GLASSWARE, MINIMIZE THE RISK OF ACCIDENTS BY POURING:
SLOWLY WITH CONTAINERS SEVERAL INCHES APART USING A FUNNEL
SLOWLY, RESTING ONE CONTAINER ON THE RIM OF THE OTHER
QUICKLY WITH CONTAINERS SEVERAL INCHES APART
QUICKLY RESTING ONE CONTAINER ON THE RIM OF THE OTHER
24
SECURING THE AREA, NOTIFYING OTHERS, AND RINSING AND TREATING EXPOSED SKIN HAPPENS AFTER:
BREAKING GLASS LAB WARE
COMBINING THE INCORRECT INGREDIENTS IN A SOLUTION
INHALATION OF NOXIOUS FUMES
A CHEMICAL IS SPILLED
25
WHAT IS NOT AN IMPORTANT SAFETY PRINCIPLE FOR WORKING IN A LABORATORY?
KNOW THE LOCATION AND FUNCTION OF EMERGENCY WASHE
IMMEDIATELY DISPOSE OF BIOHAZARDS AFTER USE
PLACE CHE
KEEP WALKWAYS AND TAB
26
A PERSON WITH CHEMICAL EXPOSURE TO THEIR EYES SHOULD IMMEDIATELY USE AN EYE RINSE FOR:
SECONDS
SECONDS, THEN RUB EYES, AND FLUSH AGAIN
MINUTES
MINUTES, PAUSING TO RUB EYES EVERY 30 SECONDS
27
THE USE OF A LABORATORY COAT IS:
ONLY USEFUL FOR PROTECTING CLOTHING UNDERNEATH.
A GOOD METHOD TO PREVENT CONTAMINATION OF RESEARCH.
CONSTRICTING DURING LABORATORY WORK.
NOT NECESSARY IN AGRICULTURAL LABORATORIES.
28
THE LEAST IMPORTANT REASON FOR DILUTING AND NEUTRALIZING STRONG CHEMICALS IS:
HIGH LEVELS OF INANE CHEMICALS = ENVIRONMENTAL DAMAGE
STRONG CHEMICALS CAN DAMAGE PLUMBING AND SEWER SYSTEMS.
FEDERAL LAW: ALL CHEMICALS MUST BE DILUTED BEFORE DISPOSAL.
CHEMICALS COULD CONTACT CLEANING STAFF.
29
INCUBATION OF BACTERIA CULTURES SHOULD NEVER BE CONDUCTED AT TEMPS GREATER THAN 30°C. WHY?
TEMPERATURES HIGHER THAN THIS WILL KILL MOST BACTERIA
