Basic lab safety principles

Lab safety must be taught to :

All employees, including service groups should:undergraduate studentsgraduate studentsprofessorsvisitors

new employeesnew proceduresa change in proceduresnew equipment

REVIEW LABORATORY SAFETY WHEN:

LABORATORY PROCEDURES MUST BE SITE

SPECIFIC !

based on your lab needs,

conditions,

and equipment

LAB SAFETY procedure ..

Must be:

written and available

Laboratory Policies and Procedures

usually common to all areas

General Procedures or Rules:

General Procedures or Rules:

no food or drink allowed in the laboratoryno mouth pipettingindividuals not allowed to work in the laboratory alonewear required personal protective equipmentno smoking in laboratorymaintain good housekeeping habits

No

food

or

drink

inside

the

lab

No

food

shall

be put

in

fridges

GLASSWARE PROCEDURES

StorageProper useCleaning Cleaning up broken glasswareDisposal of broken glassware

Glassware handling cont

• Bad practices

• Good practices

Handling and Using Lab Equipment

Proper installationTraining on proper useManuals or written procedures availableInspections MaintenanceDOCUMENT

SAFETY EQUIPMENT

proper equipment must be availablerequires training for the location so individuals know how and when to use equipment appropriatelytraining on the correct

maintenance &storage is alsonecessary

SAFETY EQUIPMENT

FIRST AID kitsEMERGENCY EQUIPMENTSHOWERS, EYEWASH STATIONSMSDS’SPPE

First Aid kits

First aid kit available and properly stocked (nothing expired)Trained first aid attendant orMedical facilities within 15 minutesEmergency numbers posted

Emergency Showers and Eyewash Stations

must be availableshowers must be tested for proper operation with results documented

MSDS Information Includes:

Nomenclature including chemical family and formulaHazardous ingredientsPhysical dataFire and explosion hazardHealth hazardSpill and leak proceduresSpecial protection informationStorage and handling precautions

Personal Protective Equipment

AGENCY MUST:Provide PPE for all employees

at no cost to the employeetrain employees how to use PPE properlytrain employees on the limitation(s) of PPEtrain employees in proper care, storage, and useful life, and disposal of PPE

Appropriate PPE:

aprons,lab coatsgloves-latex,nitrile,neoprenegoggles, face shields, safety glassesrespirators-full, partial, dust masknoise protection

PPEs

Gloves

Ultraviolet rays

Transportation of

chemicals

DISPOSAL PROCEDURES

chemical wastesorganisms, diseases, animalsglasswarespillssharps

DISPOSAL PROCEDURES CONT.

Trained persons designated to handle disposalMeet all required rules and regulationsProper collection containersWaste collection contractsDoes not expose humans, animals, plants, etc upon disposal - may include decontamination, sterilization, incineration, autoclaving

Flammable – Any substance that will burn if exposed to an open flame.

Explosive – A substance that may explode if exposed to heat or flame.

Chemical Hazard Symbols and Definitions

Toxic/Poison – A substance that can lead to death if inhaled, ingested, or absorbed by the skin.

Corrosive – A substance that can destroy or burn living tissue and can eat away at other materials.

Chemical Hazard Symbols and Definitions

Irritant - A substance that causes inflammation upon contact with skin or mucous membranes.

Environmental - Substances that are harmful to the environment. They must be disposed of properly, not washed down the drain.

Chemical Hazard Symbols and Definitions

Chemical strage

Problems with Alphabetical Chemical Storage

Acetic acid + acetaldehyde small amounts of acetic acid will cause the

acetaldehyde to polymerize, releasing large amounts heat

All CERAMIC restorations on:

Maleic anhydride + magnesium hydroxide potentially explosive reaction

Use of Perchloric Acid

Perchloric acid is a powerful oxidizing agent that may react explosively with any organic compound or reducing agent. If you consider how many materials that encompasses, you quickly realize the magnitude of the hazard that this acid presents. It reacts with alcohols to form very unstable (to shock or heat) perchlorate esters, which have the same shattering power as nitroglycerin.
