Requires a chemical hygiene plan maintenance websiteRequires a Chemical Hygiene OfficerSpecifies laboratory safety equipmentSpecifies emergency equipmentMandates a chemical management programRequires posting of signs and labels for chemical hazardsEstablishes Standard Operating ProceduresRequires professional development (specific)4Site Staff Chemical HygieneTraining of ALL science teachers & responsible administrators must be completed and documentation forwarded to Beverly Cea by October 3, 2014.Training must be face to face (to allow for Q & A). This training completes the additional hour required for the 0.5 CEU for today.This is a legal requirement no exceptions no free passes. Ideally, training is completed prior to any labs being performed; this is especially critical for new teachers.Training must be initial and ongoing at a minimum an annual refresher must be given.5Update & Maintenance of Local CHPA local copy of the CHP must be maintained with local site information such as chemical hygiene officer and emergency response information.(Communicate location of sites local copy of CHP and site specific procedures.)6Personnel with Responsibilities in the GCS Chemical Hygiene PlanSuperintendentPrincipalsGuilford County Chemical Hygiene OfficerSite Appointed Chemical Hygiene OfficerScience Teachers

An effective safety program and compliance with federal and state regulations is a SITE & GCS TEAM Effort.Everyone must do their part to fulfill these requirements.

Provide additional employee training for newly identified physical or health hazards.

10Globally Harmonized System created by the United Nations

Also known as GHS

A system for standardizing chemical classification and labeling for world-wide implementationLabels: Signal words (Danger/Warning) Hazard statements Precautionary statements Pictograms (9) SDS-16 categories Training http://www.osha.gov/Publications/HazComm_QuickCard_SafetyData.html11New SDS (formerly MSDS) format:http://www.osha.gov/Publications/HazComm_QuickCard_SafetyData.htmlHazard classification of chemical hazards Revised labeling provisions that include requirements for: Standardized signal words Pictograms Hazard statements Precautionary statements

12GHS looks at:

Class-nature of hazard Category-degree of severityA chemical can pose a physical hazard or a health hazardPhysical hazards are exhibited by certain chemicals because of their physical properties (e.g. flammability, reactivity, etc.)

These chemicals fall into the following classes:

Flammable liquids or solids

Combustible liquids

Compressed gases

Explosives

Organic peroxide: May react explosively to temperature/pressure changes

Oxidizers: Chemicals that initiate or promote combustion in other materials

Pyrophoric materials: May ignite spontaneously in air temperatures of 130F or below

Unstable materials

Water reactive materials13

Health hazard - Occurs when a chemical produces an acute or chronic health effect on exposed employees14Purchasing & Procurement ProceduresWork from inventory (Do we already have some of it? How much? Where is it?)Small amounts (microchemistry) Ideally - Store no more than one years supplyNever exceed the shelf life of a chemicalCheck with the SACHO for quantities, special hazards, and regulations (Is it banned? Does it require special permission?)Must follow proper purchasing proceduresDO NOT accept donated chemicals!!

15Chemical Inventory, Storage, & AccessOSHA Hazard Communication Standard 29 CFR 1910.1200 Inventory must be complete and currentMinimize quantitiesLabel properlySeparate according to hazard category and compatibilityDate upon receiptStore away from heat and direct sunlight16Chemical Storage RoomDesignate a central place for chemical storageLIMIT ACCESSDesignate a central place for waste storageUse a uniform labeling systemCheck inventory annuallyReduce duplicationClear aisles

17Why Maintain Chemical Inventories?National Research Council (1995), Prudent Practices in the Laboratory: Handling and Disposal of Chemicalshttp://www.nap.edu/books/0309052297/htmlOSHA Lab Standard-29 CRF 1910.1450; Appendix A, Section D.2.bChemical Procurement, Distribution, and StorageStored chemicals should be examined periodically (at least annually) for replacement, deterioration, and container integrity.OSHA Lab Standard 29 CFR 1910. 1450; Appendix A, Section D.2.d; Chemical Procurement, Distribution, and StoragePeriodic inventories should be conducted, with unneeded items being discarded or returned to the storeroom / stockroom.OSHA Hazard Communication Standard 29 CFR 1910.1200Inventory must be complete and current

19Safety Data Sheets (SDSs)SDSs the foundation of chemical safety!The SDS/SDS tells you:What chemicals are contained in a productWhat the hazards areWhat precautions you need to takeWhat to do in the event of a spill or exposure

20Elements of the Material Safety Data Sheet16 Sections Review Handout with Students posted on GEMS:

How to Read an MSDS 16 sections for new SDShttp://www.osha.gov/Publications/HazComm_QuickCard_SafetyData.html

21MSDSs Household ChemicalsOnce Household chemicals are used in a lesson you MUST have an MSDS/SDS for them.Vinegar, Household Ammonia, Bleach and other household chemicals when used at schoolAny substance used in a lesson requires a MSDS/SDSObtain from the company or Internet
