Bio Science: Safety

What do each of the four (4) diamonds: Yellow, Red, Blue, and White in the MSDS safety diamond represent?

1. Explain why warning signs in labs are symbol heavy

2. List and explain purpose of preventative safety equipment

3. List and explain purpose of responsive safety equipment

4. Explain what to do if an incident occurs5. Draw an accurate floor plan of their

classroom lab safety equipment locations

Preventative – Used to reduce the risk of an accident and avert exposure.

Responsive – Used when an incident has occurred to minimized damage and contain exposure

What do these tell you?

What do these sign tell you?

Do you think there is a need to have universal symbols for cautioning people? Why? Come up with three (3) reasons.

Images from IFSTA Hazardous Materials for First Responders 4th Edition Ch. 2

Here are examples of International Organization for Standardization (ISO) and Globally Harmonized System (GHS) safety symbol you will see in the lab.

What do you notice about these that make them easy for anyone

to recognizes, give three (3) examples.

Two (2) types:Preventative – Used to reduce the risk of

an accident and avert exposure.Responsive – Used when an incident has

occurred to minimized damage and contain exposure

The number one purpose of all types of safety equipment is to prevent human

injury and loss of life.

List three (3) pieces of personal protective equipment (PPE).

In addition to these the lab is out fitted with other equipment. We ALWAYS use preventative equipment.

Safety Signs Fume Hood

Used to contain & evacuate fumes/

gasses

Goggles, Aprons, and Gloves

We ALWAYS use preventative equipment.

RespiratorsAbsorbent Station Pads Hand Wash

Station

Insure we do not transfer contaminates

out of the lab

Helps keep accidental spills/ drips contain and

easy clean up

Used to keep contaminants from entering

respiratory system

Used in the unfortunate event of an incident. We hope to never use these.

Hand Wash Station

Eye Wash Station

Safety Shower

Fire Extinguisher

Absorbent Pads

Spill a biological or chemical on hands:Immediately wash with Soap and water for 15min,

lab partner should notify instructor immediately.Spill or splash a biological or chemical on face or in eyes:

Immediately rinse out in eye wash station until instructor says to stop. Lab partner should help you over to station then get instructor.Spill or splash a biological or chemical all over body:

Immediately remove all clothes except undergarments and rinse under safety shower until instructor says to stop. Lab partner should get instructor.

Spill Chemicals or Biologicals on lab bench or floor: Take care of your body first if it contacts you.Notify others around you and instructor.Clean up.

Fire:Notify instructorPull fire alarm if instructed and prepare to evacuate

Gas or toxic fume leak:Notify instructorPrepare to evacuate room

A/B Partner QuizWhy is a wash station both preventative and

responsive safety equipment?

Using an entire page in your lab book, sketch a floor layout of the lab as is looking down on it. Include all permanent structures: doors, benches, tables, cabinets, fume hood, etc.

Now, locate all of the safety equipment we talked about and draw it into your layout.
