      • into contact with it
      • A substance may be hazardous because it is
      • explosive, flammable, harmful, irritant,
      • corrosive, toxic, produces a chemical reaction
      • or an allergic reaction
    • Harmful Substances

    • Legislation
      • The Health & Safety at Work Act 1974
      • The Management of Health & Safety at Work Regulations 1999
      • The Control of Substances Hazardous to Health (COSHH) Regulations 2002
      • The Chemicals (Hazard Information & Packaging for Supply) Regulations 2002 (CHIPS)
    • The Health & Safety at Work Act 1974
      • “ It shall be the duty of every employer to ensure, so far as is reasonably practicable, the health, safety and welfare of all employees” :
        • Safe plant and systems of work
        • Safe use, handling, transport, storage of substances and articles
        • Provision of information, instruction & training
        • Safe place of work including access and egress
        • Safe working environment with adequate welfare facilities
        • A written safety policy if more than four employees
        • Further duties extend this requirement to include non employees
      • who may still be affected by the work undertaking
    • The COSHH Regulations 2002
      • Designed to protect employees and others from the effects of harmful substances
      • Provides more specific guidance than the general arrangements
      • Outlines an 8 step approach to managing harmful substances in the workplace
    • The COSHH Regulations 2002
      • Not included under the COSHH regulations:
      • Biological agents outside the employers control (flu, colds, measles etc)
      • Asbestos & Lead
      • Substances that are hazardous only because they are:
        • Radioactive
        • At high pressure
        • At extreme temperatures
    • The CHIPS Regulations 2002
      • CHIP requires the supplier of a dangerous chemical to:
      • Identify the hazards (dangers) of the chemical, this is known as ‘classification’;
      • Give information about the hazards to their customers. Suppliers usually provide this information on the package itself (eg a label) and, if supplied for use at work, in a material safety data sheet (MSDS);
      • Package the chemical safely
    • The 8 Steps to Reducing Risk
      • Step 1 Assess the risk
      • Step 2 Decide what precautions are needed
      • Step 3 Prevent or control exposure
      • Step 4 Ensure control measures are used
      • Step 5 Monitor the exposure
      • Step 6 Carry out health appropriate surveillance
      • Step 7 Plan for accidents and emergencies
      • Step 8 Provide employees with information, training and supervision
    • Step 1- Assess the Risks
      • Identify the hazardous substances present in the workplace:
        • Warning labels
        • Material Safety Data Sheets (MSDS)
        • HSE website – EH40/2005
        • Dept of Health
        • Trade Associations
        • Specialist agencies
    • Chemical Hazard Symbols
      • Oxidising Agent
      Radioactive Biohazard Explosive Toxic Flammable Corrosive Harmful Harmful to the environment
    • Material Safety Data Sheets (MSDS)
      • Legal requirement placed on commercial suppliers of chemicals and products
      • 16 Headings
      • Updated as appropriate
      • Not designed as a risk assessment
      • Use of Risk Phrases
      • Not all harmful substances will have a MSDS
    • Difficulties With Identification
      • Unlabelled containers
      • Substance cannot be detected by our senses
      • Hazard results from reactions between chemicals
      • Gradual increases in concentration
      • Specialist competence required
      • Nursing home faces chemical alert
      • Thirteen residents had to be evacuated from a nursing home after chlorine-based chemicals were accidentally mixed together. Firefighters were called to the Nyton House Nursing Home, in Aldingbourne, West Sussex, on Wednesday morning to a strong smell of chlorine fumes.
      • The chemicals had been placed in a bucket, but were removed by fire crews to a sealed container. Four people were treated in hospital for the effects of the fumes.
      • West Sussex Fire and Rescue Service said it seemed two chlorine-based chemicals used for the swimming pool at the nursing home had been mistakenly mixed together by a workman, causing the release of the fumes
    • Assessing The Risk
      • Describes the likelihood of harm occurring:
      • Risk = Severity of Harm x Extent of Exposure
    • Exposure - Dose
      • Amount Of Substance
      • Method Of Use
      • Form Of Substance
      • Routes Of Entry
      • Length Of Exposure
      • Existing Controls
      • Consider everyone who may be exposed
      • Working environment
    • Amount Of Substance
      • Can be difficult to determine
      • Factors to consider include:
        • Varying concentrations over time
        • Duration of exposure
        • Accurate measuring of quantities
        • Changes to form of substance
    • Form Of The Substance
      • Solid – Liquid – Gas
      • Dust The term used for small particles of a solid suspended in the air
      • Vapour The term used to describe the gaseous state of solids or liquids
      • Fumes Formed when solid vapours condense in the atmosphere
      • Mists Small liquid droplets that form when a liquid is atomised
    • Changes Of Physical Form
      • S olid To Dust – Asbestos & Hardwood Dust
      • Liquid To Vapour – Petrol
      • Solid To Fumes – Lead Oxide, Chlorine gas
      • Liquid To Mist –Paint Spray, Pesticides
      • Fumes poison workers at animal charity premises
      • Norfolk animal charity and two of its managers were fined a total of £30,100 and ordered to pay £21,120 costs by Norwich magistrates after three workers were badly affected by inhaling toxic fumes from rat poison. All parties pleaded guilty to all charges.
    • Routes of Entry Into Body
      • Inhalation
      • Ingestion – Food/Drink
      • Absorption – Skin/Cuts
      • Injection
    • Route of Entry!
    • Step 2 - Decide What Precautions are Needed
      • Compare existing control measures against recognised management standards:
      • www.hse.gov.uk/coshh essentials
      • Industry sector best practice

      • Provide welfare facilities
      • Good personal hygiene
      • Safe storage of harmful substances
      • Safe systems of work for routine and non routine activities
    • Personal Protective Equipment (PPE)
      • Use as a last resort if only control measure
      • The hazard remains unaffected
      • It’s effectiveness relies on correct use
      • Only the wearer is protected
      • Effectiveness may be reduced over time
      • Supplied, maintained, cleaned, stored and replaced free of charge
      • May require specialist fit testing etc
      • May require specialist disposal
      • Can be uncomfortable to wear

      • Systems for reporting defects
      • Accident and incident reporting
      • Refresher-Update training
    • Step 5 – Monitor Exposure
      • Mainly concerned with measuring the concentration of hazardous substances in the air likely to be breathed by employees or others
      • May not be required if other methods of adequately controlling employees exposure can be demonstrated
    • Step 6 – Health Surveillance
      • This is usually only undertaken in specific instances where:
      • There is an identifiable disease or other identifiable adverse health outcome linked to the work
      • The disease or health effect may be related to exposure
      • There is a likelihood that the disease or health effect may occur
      • There are valid techniques for detecting indications of the disease or health effects exposure to a substance linked to a particular disease or adverse health effects
    • Step 7 – Plan for Accidents and Emergencies
      • Applies to circumstances where the risk of an accident or emergency involving exposure to a hazardous substance goes beyond the risks associated with normal day to day work
    • Step 8 – Provide Employees with Suitable Information- Instruction - Training
      • Legal requirement to provide in a format likely to be understood
      • Updated as required
      • Based on required level of competency
      • General Approach – Low Level
      • Hazard specific – WELs
      • Provided by a competent person
