Before we start a wee word about ignorance and incompetence

Before we start…a wee word about Ignorance and Incompetence…..

  • Before using my chemical reagent, what do I need to do?


Dcu faculty of science and health safe lab module 2 basic considerations for chemical reagent use1

DCU Faculty of Science and Health-Safe Lab Module 2- Basic Considerations for Chemical Reagent Use

  • Obtain a copy of the Material Safety Data Sheet (MSDS) for the chemical Reagent. You will get this from the manufacturer of the reagent e.g.. Sigma Aldrich www.sigmaaldrich.com.

  • The MSDS gives you a ‘safety blue print’ for all the hazards associated with your given reagent, and is your first point of reference.

  • It should be noted that as from December 2010, the Global Harmonisation System for the labelling of chemical agents will come into effect. What this means for us as users is that there are will be a ‘crossover’ period between the older system for the safety classification of chemical reagents, and the newer G.H.S. system. Total implementation of the new G.H.S. system will be effective by June 1st 2015. For more info. See the below link on www.

  • NEW CHEMICAL HAZARD SYMBOLSEFFECTIVE FROM 1ST DEC 2010 (AS PER G.H.S. LEGISLATION)

Identify all the risks associated with the reagent by carrying out a H.S. assessment for the reagent. This is done through the completion of a H.S.A.F. (abbv.Hazardous SubstanceAssesment Form).*

Filling out a H.S.A.F. makes you think about how you are actually going to use the reagent in your given workplace and lets your supervisor know that you have considered all the safety implications in using the reagent.

* See http://www4.dcu.ie/science_and_health/safety_info.shtml

Filling out a H.S.A.F. on a reagent is key to good reagent safety awareness. Completing a H.S.A.F. makes you ask yourself the following:

  • Am I confident/competent enough to work safely with this reagent?

  • Where do I intend working with this reagent and where will I store it when in use?

  • What are the Risk Numbers/Phrases , and Safety Numbers/Phrases designated to the reagent?

  • When G.H.S. is fully in place, these phrases will be replaced by Hazard Numbers/Phrases and Precautionary Numbers/Phrases

  • Can the substance be replaced by a substance less hazardous to me?

  • Have I got the glassware, laboratory equipment, Personal Protective Equipment (abbv.P.P.E.) to work safely with the reagent?

  • How much reagent do I really need to do my work?

  • Do I know what to do in case of an accidental release of the reagent?

  • Do I know what basic first aid measures I should follow if I am exposed to the reagent?

  • How will I disposes of the excess reagent and reagent waste streams I will generate?

  • When I am physically using my chemical reagent, what do I need to consider?


Dcu faculty of science and health safe lab module 2 basic considerations for chemical reagent use8

DCU Faculty of Science and Health-Safe Lab Module 2- Basic Considerations for Chemical Reagent Use

  • Do I need to work in a fumehood? Is it serviced and functioning correctly?

  • What Personal Protective Equipment will I need to use? In all cases for chemical reagent use, you will need a buttoned lab coat and safety glasses, as a minimum. Disposable nitrile gloves are also commonly used in the School of Chemical Sciences e.g.. “SemperGaurd” Nitrile Gloves-available from Fischer Scientific Ltd.

  • Date chemical reagent container on opening it-preferably apply label - and use a pencil to write date!!!

  • Will I need to instruct others that I share the lab with, about this reagent? Should I work outside normal university hours with the reagent??

  • Is the substance teratogenic/mutagenic/carcinogenic? Do I need to be monitored for exposure? If I am pregnant is there risk to me and my unborn child?? Who do I need to inform?

  • Is appropriate first aid/fire fighting equipment available? Am I trained to use a fire extinguisher?

  • Do I actually know what to do in the event of an emergency with this reagent eg. Spillage, splash to my body etc?

  • When I am finally finished using my chemical reagent, what then?


Dcu faculty of science and health safe lab module 2 basic considerations for chemical reagent use10

DCU Faculty of Science and Health-Safe Lab Module 2- Basic Considerations for Chemical Reagent Use

  • Where will I store leftover reagent? Return to a central storage area or keep in my lab? What are the storage options available to me?

  • How do I safely clean glassware contaminated with reagent? If reagent container is empty, how do I safely clean/ dispose of it?

  • How do I safely remove/dispose of my reagent waste that I generate?

  • Consult academic supervisor, safety adviser, in-house safety procedures etc. if you cannot answer these questions!!!

  • To sum up…..


Dcu faculty of science and health safe lab module 2 basic considerations for chemical reagent use12

DCU Faculty of Science and Health-Safe Lab Module 2- Basic Considerations for Chemical Reagent Use

  • Fill out a H.S.A.F. before starting work with that reagent. Send completed H.S.A.F. to supervisor/safety adviser for approval.

  • H.S.A.F. is key to every single chemical reagent you will ever use in the Faculty of Science and Health. (For example seehttp://www.dcu.ie/chemistry/policy_documents_safety.shtml)

  • Consult your project supervisor.

  • Consult your local Safety Rep/Advisor

  • Consult your technical Support Staff

  • Consult your colleagues

  • Consult University Health and Safety Office

  • If you have any doubt about chemical reagent safety---ASK! ASK!! ASK!!!!!!!
