Important Facts You Need to Know

Material Safety Data Sheet

• Acronym: MSDS
• Required for all HAZARDOUS materials
• Regulated or enforced by OSHA
• Designed to provide workers and

emergency personnel w/proper procedures for handling or working w/a substance

MSDS contents

• Chemical Name

– Common name also given

• Stability

– Room temp, refrigerate, freeze

• Reactivity

– Do not mix w/ ,,,

MSDS contents

• Physical Data

– Melting or boiling point

• Toxicity
• Health Effects and

First Aid

– Inhalation – Skin contact

• Storage and disposal
• Spill / Leak cleanup

MSDS are meant for:

• Workers who store or

handle the material

• Workers who use the

material and may be exposed to it

• Emergency workers such as

fire fighters or EMT who may be exposed

Where to find an MSDS

• Binder in the laboratory

– Organized alphabetically

• On line or from the Mfg.

– Can usually request on line copies if lab does not have one

• Companies are required to send with the

1st shipment of a chemical or hazardous material

Hazardous Chemical Label

• What does each area

mean?

– Red: Flammability – Yellow: Reactivity or instability – White: Special hazard – Blue: Health and Hazard

Hazardous Chemical label

OSHA

• Occupational Safety and Health

Administration

• Ensures worker Safety and protection
• Oversees MSDS
• Most common violation they cite companies

for is:

– Improper chemical labeling

EPA

• Environmental

Protection Agency

• Responsible for

protecting the environment

• Audits companies to

verify they are not improperly disposing of materials down the drain

DOT

• Department of

Transportation

– Need to know what they are transporting – Need copies of MSDS for hazardous materials – Need special permits and containers for hazardous materials

PPE

• Personal Protection

Equipment

– Lab coat – Safety Glasses / Goggles – Gloves – Face shield – Respirator

Proper PPE

• Closed toe shoes
• No contacts
• No loose or hanging clothes such as ties
• Minimal jewelry
• Lab coat, safety glasses and gloves most

common

• Glasses required for all liquid experiments

FIRES NEED 3 THINGS TO START

• Oxygen (Air)
• Fuel (any

material that will burn)

• Heat (sparks,

matches, flames)

Major Causes of Fires

• Carelessness with

smoking and matches

• Misuse of electricity

(overloading a circuit

• r overuse of

extension cords)

• Improper rubbish

disposal

• Improper storage of

flammables (such as gasoline)

• Arson

EXTENSION CORDS

• Avoid using extension cords

whenever possible

• Do not exceed specified

amperage

• Do not run extension cords

across doorways or anywhere they can be stepped on

• Do not plug one extension

cord into another and never plug more than one extension cord into an outlet

GENERAL FIRE SAFETY

Keep combustibles away from heat producing devices. Cap and store combustible liquids properly. Never prop open emergency doors. Fire doors not only let people out, they keep fire from spreading.

In the event of a fire, stay calm and RACE…

• R-rescue any patient

in immediate danger

• A-pull the alarm and

notify other employees of the location and type of fire

• C-contain the fire by

closing doors and windows

• E-extinguish the fire
• r evacuate the area

TYPES OF FIRE EXTINGUISHERS

• Pressurized water

extinguishers (Class A fires only)

• Dry Chemical

extinguishers (ABC or BC)

• Carbon dioxide

extinguishers (Class B and C)

• Foam (or AFFF and

FFFP) extinguishers

• Class D extinguishers

Fire Safety

• You should know…

– Where the fire extinguisher is located – How to use the fire extinguisher

• PASS

– Pull – Aim – Squeeze – Sweep

Proper Gowning

• When gowning for a

clean room, the process is from top to bottom

– Hairnet – Beard cover – Bunny suit – Booties – Gloves – Glasses

Clean Room Classifications

• Classified by the number of particles found

in the air in the lab.

– The number is what your count has to be less than.

• For example, a class 1,000 clean room has to

have less than 1,000 particles in the air

• So, which classification is the cleanest?

– Class 10 or 100

Particle size plays a role

Test your knowledge

• What would be the first steps if you have a

spill in the lab?

– Alert everyone, proper PPE, follow MSDS to clean up

• What is the acronym for use of fire

extinguisher?

– PASS (pull, aim, squeeze, sweep)

Test Your Knowledge

• What is the proper order of gowning for a

clean room?

– Top to bottom: hair, face, body, feet, hands

• Who is responsible for employee safety?

– OSHA

• Who is responsible for protecting

environment?

– EPA

Lab Cleaning and Waste Disposal

• Lab Surfaces

– Should be cleaned before and after experiments – 10% bleach or ethanol most commonly used

• Waste Disposal

– Be sure hazardous and biohazardous materials are disposed of properly – Wash materials down the drain with copious amounts

• f water

– Paper wrappers and paper towels go in regular trash

Sterilizing Equipment and Materials

• Autoclaves: work by steam and pressure

– Commonly used for equipment sterilization – Indicator tape used to verify the cycle was run

• UV light

– Example is goggle sanitizer – UV light causes mutation in DNA of bacteria

• Bleach or ethanol

– Often used to clean benches, may be used to sterilize equipment during an experiment

• Flames

– used to sterilize tops of tubes for microbiology

Test Your Knowledge

• When should you sanitize your bench?

– Before and after experiments

• What equipment uses steam and pressure

to sterilize equipment?

– Autoclaves

• Where do you discard paper towels after

drying your hands?

– In regular trash
