Laboratory Safety: Study Guide

A safety shower should be used if you spill a chemical on your skin.

Medical attention/advice should be sought immediately if an eye injury occurs.

Students should line up alphabetically in the designated area during a fire drill.

Flammable chemicals be stored in the Flammable Safety Cabinet

Accidents can cause serious injury or even death.

If you must smell a chemical do not put your nose directly over the sample but gently waft the vapors instead.

You have a Right to Know about the hazardous chemicals you use on the job and how to work safely with those chemicals.

OSHA created the Hazard Communication Standard.

Health hazards and physical hazards are the 2 categories for chemical hazards.

Any glassware with breaks should be discarded in the glass waste container.

The UV light can damage your eyes.

The use of a liquid near an electrical outlet is unsafe and could lead to electrical shock.

Backpacks are not allowed in the classroom/laboratory and can be the cause of slips and falls.

Shoes that completely cover your feet should be worn in the laboratory. 

It is necessary for you to wash your hands before leaving the laboratory so that you do not take any hazardous chemicals with you.

If a chemical is splashed in your eye, you should flush for 15 minutes with the eye wash.

MSDS sheets should always be available for laboratory employees.

Chemical stability is how a chemical changes when subjected to different conditions.

Toxicological refers to how a chemical is tested for health hazards.

Section numbers and titles can vary with the arrangement of an MSDS?

Examples of common causes of fires in the laboratory are accidental ignition of flammable liquids and defective bunsen burners

No open flames or uneven heating devices should be used to heat a flammable chemical.

If toxins or gases get trapped, they can have direct contact with your eyes and cause eye injury.

Toxic chemical can have an effect on one or more body organs or systems. It can damage the lungs, stimulate or depress the nervous system or damage other systems, such as kidneys or liver.

Toxic effects are dependent on the dose- how much exposure you have over what period of time.

It is the chemical manufacturers’ job to determine a chemical’s hazards and provide MSDS and chemical labels to communicate these hazards. It is an employer’s jon to maintain MSDS and provide safety training.

It is NEVER acceptable to have food in the laboratory.

You should move to fresh air if you are exposed to an inhalation hazard.

Vapor density is whether chemical vapors will rise or stay close to the ground.

Flashpoint is the temperature at which a liquid gives off enough vapors to burn.

When using a fire extinguisher, PASS stands for: Pull the pin, Aim the extinguisher at the base of the fire, Squeeze the handle and release the agent, Sweep the extinguisher from side to side across the base of the fire until it goes out.

The four things that an MSDS tells you is: What chemicals are contained in a product, what the hazards are, what precautions you need to take and what to do in the event of a spill or exposure

The three factors that assist in exposure control are Engineering controls, PPE (personal protective equipment) and hygiene (hand washing)

Evacuation and isolation of area, evaluation by trained responders, containment and cleanup are all examples of what to do in the event of a spill or leak.

The scale for hazardous materials is 0 no hazard to 4 extreme hazard

Locations of Emergency Safety Equipment:

1.	Burn Kit: There is one in each room- Rm 44: near goggle sanitizer and Rm 45: behind door near pipette tip wire rack

2.	Eye Wash: There is one in each room- Rm 44:Under safety shower and Rm 45: On wall near biosafety cabinet

3.	Fire Extinguisher: There is one in each room- Rm 44: Front of room near door and phone and Rm 45: Back of room near exit door to parking lot

4.	First Aid Kit: There is one in each room- Rm 44: near goggle sanitizer and Rm 45: behind door near pipette tip wire rack

5.	Safety Shower: Back left corner of room

    Match the color to the hazard for NFPA- The National Fire Protection Association Labeling

6.	White: Other hazards or special handling

7.	Red: Flammability

8.	Yellow: Reactivity

9.	Blue: Health

		The three things necessary for a fire and depicted in the fire pyramid are an ignition source, oxygen and fuel.
