Chemical Lab Safety Compiled by: Dalton R. Fortin, RCh, MSc Course Facilitator DO NOT UPLOAD ONLINE. DO NOT SHARE WITHOUT PERMISSION FROM THE COURSE FACILITATOR. Objectives At the end of the training session, the student/staff should be able to know the following: ▪ Basic Personal Protective Equipment (PPE). ▪ Laboratory hazards ▪ First aid ▪ Location and proper use of safety shower, eye wash and safety kit. ▪ Location of Fire Extinguisher. ▪ Location and Use of Spill kits. ▪ Location and proper use of fume hood and safety cabinet. ▪ Basic information about chemical compatibilities. ▪ Information about Material Safety Data Sheet (MSDS). ▪ Location and information in emergency response guides. ▪ Emergency evacuation route. ▪ Chemical Waste Management. Chemical safety is the application of the best practices for handling chemicals and chemistry processes to minimize risk, whether to a person, facility, or community. It involves understanding the physical, chemical, and toxicological hazards of chemicals. Why does it matter? Safe working protects: – You because – Other lab workers – Cleaners – Visitors – Your work Personal Protective Equipment Personal Protective Equipment – Video Video Reference : Bionetwork NC Community Colleges Lab Safety – General Practices Do not apply cosmetics, eat, or drink in the lab. NoFood ta702_dt Never eat, drink or smoke in a laboratory. Never apply cosmetics. Long hair must be tied back. Do not taste any chemical! briggs-R1-12A Always wash your hands before you leave and especially before eating. Lab Safety - General Practices How to transport chemicals? Individuals transporting the chemical MUST BE FAMILIAR with the MSDS of the chemicals being transported. ▪ Wear appropriate PPE. ▪ Know the hazards of the chemicals and what to do in the event of a release or spill. ▪ Do not carry containers by hand. Use bottle carriers or carts with secondary containment. Safe Chemical Handling Video Reference : Bionetwork NC Community Colleges Material Safety Data Sheet Materials Safety Data Sheet (MSDS) is a technical document that contains information on the potential hazards and ways to handle the chemical products for safety purposes. It is important to know how to read and interpret safety labels and SDSs (updated from Material Safety Data Sheets (MSDS) in 2016). SDSs use the Globally Harmonized System (GHS), a universal system designed to provide a consistent method of communicating chemical hazards. Material Safety Data Sheet Number Blue Red Yellow Code 0 No unusual hazard Not combustible Not reactive when mixed with water 1 May be irritating Combustible if heated May react if heated or mixed with water but not violently 2 May be harmful if The combustible liquid Unstable or may inhaled or absorbed flash point of 100 0F to react violently if 200 0F mixed with water 3 Corrosive or toxic. The flammable liquid Explosive if shocked, Avoid skin contact or flash point below 100 heated under inhalation 0F confinement or mixed with water 4 May be fatal on short Flammable gas or Explosive material at exposure. Protective extremely flammable room temperature equipment required liquid Laboratory hazards EU Chemical Hazard Symbols Fire Breakage of glassware Sharps Spillages Pressure equipment & gas cylinders Extremes of heat & cold Chemical hazards Biological hazards Radiation And many more! Laboratory hazards Flammable substances Use minimum quantity Store in special storage cabinet Use temperature-controlled heating sources (eg water-bath rather than hot- plate or Bunsen burner) Laboratory hazards – Broken Glassware Use correct techniques for the insertion of tubing onto glassware Never use glassware under pressure or vacuum unless it is designed for the job and suitably shielded Dispose of chipped or broken glassware – it is a risk to you and others Always dispose of broken glass in a glass bin or sharps bin and not in a general waste bin Laboratory hazards – Spillages Clear up spillage promptly. You will already have determined how to do this as part of your risk assessment. Dispose of any hazardous material as toxic waste. Messy workers are usually poor workers!! General Tidiness Keep your workplace tidy. Clear up waste, deal with washing up and put things away as you finish with them. Make sure everything is safe before you leave things unattended. A tidy laboratory avoids accidents to everyone. Safe Chemical Handling Video Reference : Bionetwork NC Community Colleges First Aid All laboratory workers should undergo simple first aid training – For ALL chemical splashes, wash with plenty of water for 10 minutes – Control bleeding with direct pressure, avoiding any foreign bodies such as glass Report all accidents to your instructor. First Aid Chemical Splash in the eyes. Flush the opened eyes for at least 15 minutes in an emergency eye wash. Chemical on the skin Immediately flush the skin with large amount of water. Remove all the contaminated clothes including undergarments and jewelries. Removing them from the victim greatly reduce the severity of chemical burn. Bleeding Hold a clean towel or any pad directly on the wound and apply hand pressure. Get medical attention immediately Safety Equipment Eye-wash-fountain ▪ Eye wash fountain thermomix_stn_Z ▪ Safety shower bsr-a500 ▪ Fire extinguisher floorplan2 ▪ Emergency exits Safety Equipment – CS lab Safety Equipment – Know how to use?

Chemical containers must be labeled with a minimum of chemical name, hazard warnings. Containers shall be dated when received and opened. Accompanying material safety data sheets must be kept. Chemical Storage – requirements Be aware of special storage conditions such as temperature, relative humidity or limited shelf life. Segregate chemicals by hazard class or compatibility. If available, use ventilated cabinets for volatile toxics and odoriferous chemicals. Use approved flammable storage cabinets for flammable liquids. Use secondary containers or trays for corrosives and toxic solvents. THANK YOU FOR LISTENING ANY QUESTION?
