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

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

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.

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.
