Observations

What is Laboratory Safety?

Lab safety is all about being aware of your surroundings as well as cultivating a specific skillset that is used to keep you, your peers, and the lab safe.

How can you be safe in the lab?

What does it stand for?

What does the Acronym RAMP stand for?

Recognize Hazards

A hazard is a potential source of danger or harm and can result from working with chemicals, equipment, and instrumentation

“toxic”, “flammable”, or “corrosive” show understanding (of the terms) describing chemical hazards.

Recognize Hazards

Obtaining information from chemical labels

Safety Data Sheets(SDS) or MSDS

SDS-a simpler and more effective way to communicate the hazards of the chemicals used.

MSDS-Provides detailed information about a specific hazardous material such as how to store it or first aid procedures

Multiple Choice

What is the difference between MSDS and SDS?

• SDS is a simpler and more effective way to communicate the hazards of the chemicals used.

• Its the exact same thing they just dropped the M

• MSDS- Manual for Safety Data Sheets

Chemical Labels (RH)

One common type of label is the

US National Fire Protection Association (NFPA)

system

Color=Hazard

Chemical Labels (RH)

Blue=Health

Red=Fire Hazard

Yellow=Reactivity Hazard

White=Special Hazard

Chemical Labels (RH)

NFPA Number System- numbers found within each color on the NFPA label.

0 = minimal hazard

1 = slight hazard

2 = moderate hazard

3 = serious hazard

4 = severe hazard

Multiple Choice

Safety Data Sheets provide some basic health information in addition to information about chemicals.

• True
• False

Multiple Choice

Which hazard does this pictogram represent?

• Flammable
• Oxidizing
• Health Hazard
• Danger to the Environment

Multiple Choice

What does the white color on the NFPA diamond stand for?

• Special Information Hazard

• Health Hazard

• Flammability Hazard

• Reactivity Hazard

Multiple Choice

What does the blue color on the NFPA diamond stand for?

• Special Information

• Health Hazard

• Flammability Hazard

• Reactivity Hazard

Assess Risk

Once a hazard(s) is recognized, laboratory safety necessarily requires an assessment or evaluation of risk from potential exposure to the hazard

Assess the Risk

have a full understanding of the nature, magnitude and probability of a potential adverse health or environmental effect of a chemical.

Considers both hazard and exposure

Open Ended

What is the importance of being able to assess the risk of certain items in the lab?

Minimize Risk

include but not limited to carrying out experiments in a fume hood with a protective shield and wearing protective gloves and goggles. 

Multiple Choice

Things can never be prevented within a lab. What's meant to happen is going to happen.

• True

• False

Prepare for Emergencies

Be ready and alert for anything!

React promptly and deliberately to emergencies

Showers, eye washes, fire extinguishers, and spill kits, escape routes

• Scream

• Get in the chemical shower

• Get on the ground and get someone to smother it with the fire blanket

Multiple Choice

What type of horseplay is okay in the lab?

• Wresting
