What should you do if a microbial culture splashed in your eyes?
A. Rinse your eyes with water for at least 15 minutes and seek medical advice.
Rinse your eyes with water for at least 15 minutes and seek medical advice: Immediate flushing of the eyes with copious amounts of water helps remove microbial contaminants and reduce risk of infection. Seeking medical evaluation ensures further care if necessary.
B. Nothing. The cultures in this course are harmless.
Nothing. The cultures in this course are harmless: Assuming cultures are harmless is unsafe, as even nonpathogenic organisms can cause opportunistic infections, especially if they contact mucous membranes like the eyes.
C. Wipe my eyes with a damp paper towel
Wipe my eyes with a damp paper towel: Wiping is inadequate for decontamination and may worsen the situation by spreading microorganisms across the eye surface.
D. Wash my face with soap and water
Wash my face with soap and water: Washing the face does not adequately address exposure in the eyes. The correct action is prolonged eye irrigation to remove microbes effectively.

It's okay to wipe surfaces with bleach solution without wearing gloves.
A. True
B. False
Full Explanation
False: Wiping without gloves would be unsafe because bleach is a strong chemical that can irritate or damage the skin on direct contact. Handling it without protection increases the risk of burns, rashes, or chemical injury. Gloves should always be worn when using bleach solutions to prevent skin contact and chemical harm. Protective equipment ensures safe cleaning practices in laboratory and healthcare settings.
A microbe that doesn't cause disease or is not a risk to the environment can be handled at which biosafety level?
A. Biosafety Level 1
Biosafety Level 1: BSL-1 is designated for microbes that pose minimal risk to humans and the environment. These organisms are non-pathogenic and can be safely handled with standard laboratory practices.
B. Biosafety Level 2
Biosafety Level 2: BSL-2 is used for organisms that pose moderate risk and may cause human disease, requiring additional precautions such as limited lab access and protective equipment.
C. Biosafety Level 3
Biosafety Level 3: BSL-3 applies to microbes that can cause serious or potentially lethal diseases via inhalation, requiring controlled access and specialized safety equipment.
D. Biosafety Level 4
Biosafety Level 4: BSL-4 is reserved for dangerous, exotic pathogens such as Ebola virus, which carry high risk of life-threatening disease and require maximum containment facilities.

What is the meaning of this sign?
A. Irritant to skin, eyes, or respiratory tract
Irritant to skin, eyes, or respiratory tract: The Globally Harmonized System (GHS) pictogram for an irritant is a diamond containing an exclamation mark (!). This symbol is used for less severe health hazards like skin or eye irritation.
B. Health hazard
Health hazard: While acute toxicity is a health hazard, the specific pictogram for a range of serious, but non-acute, long-term health issues (like carcinogenicity, mutagenicity, or respiratory sensitization) is a diamond containing a human silhouette with a starburst over the chest (often called the "man exploding" symbol).
C. Acute toxicity; fatal
cute toxicity; fatal: The skull and crossbones symbol is an internationally recognized icon representing poison or danger of death. In the GHS, this specific pictogram is used for substances that are toxic or fatal even after only a short exposure to a small amount.
D. Explosive
Explosive: The GHS pictogram for an explosive substance is a diamond containing a bomb undergoing an explosion
