akj-nisp

*akj-nisp*ObjectiveBy the end of this course, you will be able to know:What are dangerous chemicalsSome properties of dangerous chemicalsHow to safely handle dangerous chemicals

akj-nisp

*akj-nisp*Ice Breaker:

Think of any chemical you know or you have used in your workplace and write it down.

2. Write one hazardous effect of the chemical.3. Write the Personal Protective Equipment you can use to handle the chemical.

*akj-nisp*Introduction The world we live in today has over 30,000 chemicals and it is certain that many more will still be discovered or manufactured.

Chemicals are vital to our existence despite the fact that they can hazardous or non-hazardous.

Chemicals must not be handled carelessly.

WHAT ARE DANGEROUS CHEMICALS?

akj-nisp

*akj-nisp*Chemicals that have toxic effects on plants, animals, humans.Examples are:Acacia gumAcetylene BenzeneBromineCarbon monoxideChlorineHydrochloric acidHydrogen sulphideSulphuric acid Sawdust etc.

*akj-nisp*Hazards of ChemicalsThere are 2 basic types of chemical hazardsPhysical HazardsHealth HazardsThe first rule of chemical safety is "Know what you are working with and how to protect yourself and others

akj-nisp

*akj-nisp*Physical HazardsChemicals are classified as having Physical Hazards if they are Explosive Compressed Gas Combustible Liquids Flammable Unstable Water Reactive OxidizersNote: Some chemicals may be safe by themselves, but become dangerous when in contact with other substances.

*akj-nisp*Health HazardsChemicals are classified as being a health hazard if they:Can cause cancerAre poisonous (toxic)Cause harm to your skin, internal organs, or nervous systemAre corrosive - such as acidsCause allergic reactions after repeated exposure

akj-nisp

*akj-nisp*Effects of chemicals and Routes of entry into the bodyyour lungs (Inhalation) if you breath fumes, mists or dustyour skin (Absorption) if liquid or dust touches or spills on you or splashes in your eyesyour mouth (Ingestion) if you eat after handling chemicals

NOTE: The effects of chemicals can be reversible or irreversible. Organs that may be affected include the kidneys, liver, reproductive or central nervous system

Mouth Lungs SkinNose

HOW CAN WE HANDLE DANGEROUS CHEMICALS?

akj-nisp

*akj-nisp*Control Strategies

Hierarchy of ControlsEngineering Controls: Methods include using Engineering controls such as ventilation or substitution of a safer chemical.

Administrative Controls: This is accomplished by incorporating safer work practices through such items as written safety policies, rules, supervision, training, work breaks and rotating work shifts.

Personal Protective Equipment: When engineering and administrative controls are not adequate, personal protective equipment becomes the last form of defense from exposure.

*akj-nisp*Other Methods of Handling Chemicals

- Labeling HMIS - Hazardous Material Identification System and NFPA - National Fire Protection Association. Both types must identify the chemical name and hazards Note: Pictures may be used to identify hazards and required protection. This information may also be on manufacturers label.

*akj-nisp*Material Safety Data Sheets (MSDS)Show chemical safety informationWritten and are provided by the chemical manufacturer. MSDS are kept in the workplace for employees useCommon name and chemical name of the substance Hazardous ingredientsPhysical & health hazards of the chemicalIdentification of chemical and physical propertiesFirst aid / emergency informationSafe handling and use information

akj-nisp

*akj-nisp*Employee Information and Training Every employee will need to attend a health, safety induction course prior to starting work. The course will address:Chemicals present in the workplaceLocation and availability of written HAZCOM programPhysical and hazardous effects of the hazardous chemicalsHow to reduce or prevent exposure to dangerous chemicalsCompany contingency plan put in place to protect or prevent employee exposure to the chemicals How to read labels and review MSDSs to obtain appropriate hazard information

What is SHOC?It means Safe Handling Of Chemicals:

Safety: in terms of Health and Environment

Purchase, Transportation, Usage and Disposal*akj-nisp*

akj-nisp

Why SHOC?Due careDue diligence Statutory requirements i. Factories Actii. Petroleum Decreeiii. Group SPDC Policy1V. HSE-MS*akj-nisp*

akj-nisp

What is contained in SHOC?Product identityProduct composition Physio-chemical propertiesToxicology informationSafety hazards and First AidEnvironmental Hazards and precautionsSpillage mitigation and disposal options *akj-nisp*

akj-nisp

Project Managers ResponsibilitiesEnsure SHOC cards are available on operation sites.Ensure compliance with SHOC guideline/regulationReport any new chemicals to SHOC custodians (ERE-ENVW) *akj-nisp*

akj-nisp

Benefits of SHOC1. Identification of HSE hazards 2. Basis first aid measuresFire fightingChemical handling and storageExposure controls and PPEsDisposal considerationTransport InformationRegulatory and other information*akj-nisp*

akj-nisp

Conclusion Chemicals are useful and dangerous. Having knowledge of the properties of any chemical before using it is very important.
