  1. T-960 Hazardous Substances This work has been produced by DGL (Aust) Pty Ltd This Learner’s Tool is about the skills and knowledge required for Segregating Chemicals DGL (Aust) facilities. 12/07/2006 Rev B

  2. WHAT ARE HAZARDOUS CHEMICALS? • Chemicals and other substances that can affect your health, causing illness or disease. • Just because a chemical is not a dangerous good means that it is not a hazardous chemical for workplace health and safety purposes • Substances dangerous to a person's health due to the length of time of exposure, the amount of chemical to which the person is exposed, the way the chemical enters the body, or how destructive to human tissue the substance is. • May be solvents, pesticides, paints, adhesives, petroleum products, heavy metals or other substances used or produced at work. • Can take many forms – liquids, solids, vapours, gases, fumes, dust. 12/07/2006 Rev B

  3. HOW CAN YOU TELL IF HAZARDOUS? • To be classified as a hazardous substance, the ingredients of the substance must be present in concentrations that are known to cause health effects. • When this is the case, the substance must be labelled appropriately to ensure that users know its hazardous. It must also be accompanied by a Material Safety Data Sheet (MSDS) setting out health effects, instructions for safe use and storage and what to do in an emergency. 12/07/2006 Rev B

  4. HOW CAN YOU TELL IF HAZARDOUS? • The easiest way to determine if a substance is hazardous is to look on the label for the words “hazardous”, “warning”, “poison”, “dangerous poison”, “harmful”, “corrosive”, or other advice about specific health effects. • In the absence of information such as labels and MSDS, you should assume a substance to be hazardous. 12/07/2006 Rev B

  5. HOW CAN IT EFFECT ME? • Hazardous substances can get into your body in different ways: Eg. - by breathing in the substance (inhalation) - absorption through the skin (dermal) - accidental swallowing (ingestion), for example by eating or smoking with contaminated hands. • Health effects may be: - acute (immediate), resulting from a short-term (usually high) exposure, OR - chronic (long term), resulting from long-term (often low level) exposure over a period of time. Chronic effects may not occur for many years – they are hard to predict in advance and when they do occur it may be hard to identify what caused them. 12/07/2006 Rev B

  6. WHAT NEEDS TO BE DONE? • Employer: must take action to prevent your exposure to hazardous substances at work, or if that is not practicable, to ensure that the exposure is adequately controlled so as to minimise risks to your health. • Employee: you have the responsibility to work safely using the control measures provided. To ensure you can work safely you have the right to be provided with information and training on any hazardous substances to which you may be exposed. This should include advice about health hazards, reading labels on containers and how to access the MSDS as well as emergency procedures, incident reporting and first aid. 12/07/2006 Rev B

  7. PRACTICAL CONTROLS Risk assessments reduce the risk of working with hazardous substances by: • Elimination – removal of hazardous substance which is not essential • Substitution – use a less hazardous substance, or a less hazardous form or process • Isolation – separating hazardous substances from the people using them by distance or barriers • Engineering Controls – using machinery, equipment or processes which minimise workplace contamination by containing or removing hazardous substances 12/07/2006 Rev B

  8. PRACTICAL CONTROLS • Safe Work Practices/Systems – having procedures about how to do the job safely • Personal Protective Equipment (PPE) – wearing PPE suitable for the type of substance, of suitable fit and compliant with relevant Australian Standards • Monitoring and Health Surveillance • for some hazardous substances it may be necessary to monitor the amount of the substance in the workplace environment • Health surveillance/screening means the monitoring of your health to identify health effects from exposure to a hazardous substance. 12/07/2006 Rev B

  9. PERSONAL PROTECTIVE EQUIPMENT The Law: • Workplace Health and Safety requirements (Acts, Codes, Regulations) describe how to prevent or minimise risk in the workplace. • There is a Code of Practice outlining specific requirements for PPE. • An employee has a duty to cooperate with his or her employer to enable compliance with the legislation in the interests of health, safety and welfare. This duty includes following the PPE requirements at the workplace. • A person (including an employee) must not intentionally or recklessly, interfere with or misuse anything provided in the interest of health and safety, which includes PPE. 12/07/2006 Rev B

  10. WHAT IS PPE? • Personal Protective Equipment (PPE) is any clothing, equipment or substance designed to protect a person from risks of injury or illness. • PPE can include: • Ear muffs and ear plugs • Respirators • Eye and face protection (eg. goggles) • Safety helmets and sun hats • Gloves and safety boots • Clothing (eg. high visibility vests). 12/07/2006 Rev B

  11. PPE IS PERSONAL! • Personal Protective Clothing is intended for an individual’s use. • Some PPE should be issued and worn on a personal basis. For example, masks and respirators – no sharing. • In some workplaces, multiple use of certain types of PPE is necessary. Apart from ensuring that multiple use PPE is correctly used, handled, stored, cared for and maintained, appropriate procedures on suitable cleaning and sterilisation must be provided. These procedures must be followed at all times. • What are we doing? 12/07/2006 Rev B

  12. WHEN SHOULD YOU USE IT? • Personal Protective Equipment should be used in conjunction with other control measures. • PPE should not be relied on as the main control measure. • PPE should be used to provide extra protection during an emergency situation such as a spill. 12/07/2006 Rev B

  13. PPE NOTES • Personal Protective Equipment: - does not reduce the hazard at the source - if the PPE fails and the failure is not detected, the risk increases significantly - people may fail to wear equipment, particularly for that ‘one off, quick job’ and take the attitude ‘it’ll be right’ - people believe they are ‘safe’ when wearing PPE and may place themselves at a higher risk. 12/07/2006 Rev B

  14. SELECTING PPE • Personal Protective Equipment should: • Be appropriate for the type of work • Give adequate protection to the user • Not create additional health and safety risks • Be compatible with other PPE being used • Fit properly • Not interfere with any medical conditions of the user • Be easy to use • Be comfortable • Comply with relevant Australian Standards. 12/07/2006 Rev B

  15. STORING & MAINTAINING PPE • PPE should be stored in a way that ensures its cleanliness and functionality. • PPE needs to be checked regularly both during storage and use. • PPE should be maintained to ensure its continued effectiveness (storage, cleaning, checking procedures and replacement criteria). • Defective PPE should be repaired or discarded. 12/07/2006 Rev B

  16. TRAINING IN PPE • Safety and Health policies and procedures • Provision, use, storage and maintenance of PPE, particularly the risks caused by incorrect use or maintenance of the equipment • Emergency procedures in case of special risks, eg. chemical spills or fires • Correct selection and wearing of PPE • Comfort and fit requirements • Limitations in use and effectiveness • Maintenance and replacement procedures • Ongoing training should be provided when work practices and equipment are updated. 12/07/2006 Rev B

  17. RESPIRATORS Safe Operating Procedures: • Where a MSDS recommends or requires the use of a respirator, the MSDS will recommend which type of filter is required for use with the chemical. • Respirators are to be selected on the basis of hazards to which the worker is exposed. • Only approved respirators are to be used. • Respirators are to be regularly cleaned and disinfected, or used once and replaced. 12/07/2006 Rev B

  18. RESPIRATORS • Any cleaning regime should follow manufacturer’s instructions – cleaning frequency is related to the use, number of wearers, and the contamination of the equipment. • What do we currently do • Respirators are be stored in a convenient, clean and sanitary and cool location. The storage cabinet must protect against extreme cold, heat, sunlight, dust, excessive moisture and contaminating chemicals. 12/07/2006 Rev B

  19. SELF CONTAINED BREATHING APPARTATUS Whenever a Material Safety Data Sheet (MSDS) indicates that Self Contained Breathing Apparatus is required to be worn when responding to a spill, ring 000 and invoke Evacuation Procedure. 12/07/2006 Rev B

  20. READING LABELS Reading labels on containers is the first step in getting health and safety information on the chemicals used in your workplace. 12/07/2006 Rev B

  21. READING LABELS • Chemicals classified as Hazardous substances have labels which show: • A symbol or key word indicating the hazard • Product name • Chemical name(s) of the substances and/or ingredients • Risk information • Directions for use • Safety information • First aid directions 12/07/2006 Rev B

  22. READING LABELS • Emergency procedures • Name and phone number of manufacturer or supplier • Expiry date (where relevant) • Reference to a MSDS. 12/07/2006 Rev B

  23. INTERPRETING SIGNS & WORDS ON LABELS • First, look to see if the label shows a dangerous goods ‘diamond’, a warning ‘signal word’ or the word ‘Hazardous’. 12/07/2006 Rev B

  24. INTERPRETING SIGNS & WORDS ON LABELS “Diamond” labels – dangerous goods • If a substance is a dangerous good it will have a ‘diamond’ sign(s) which indicate a type of hazard. Dangerous goods ‘diamond’ indicates an immediate hazard and not a health risk. • In addition, some labels show the Packing Group (abbreviated as PG), which indicates the degree of danger: • PG I – great danger • PG II – medium danger • PG III – minor danger 12/07/2006 Rev B

  25. INTERPRETING SIGNS & WORDS ON LABELS Poisons Label – poisons • One of the following ‘signal words’ indicates that the substance in the container is classifies as a scheduled poison. DANGEROUS POISON POISON WARNING CAUTION 12/07/2006 Rev B

  26. INTERPRETING SIGNS & WORDS ON LABELS Hazardous Label – hazardous substances • Some containers have the word ‘Hazardous’ in red. • Detailed information on the ‘Hazardous’ label include: • Name of the substance and ingredients (Trade name and common name are given. For mixtures, each chemical which is hazardous is usually listed as an ingredient) • Risk phrases (A general description of the hazards. Also written as an alpha-numeric classification number, Eg. “Irritating to Skin” (R38). Phrases are chosen by the supplier from a standard list of phrases based on the health criteria classification). 12/07/2006 Rev B

  27. INTERPRETING SIGNS & WORDS ON LABELS • Safety phrases (Provide information on safe storage and handling and personal protection. Can also be written as a alpha-numeric classification number, Eg. “Wear suitable protective clothing” (S36). Phrases are chosen by the supplier from a standard list). • Directions for use (Provides directions on how the substance should be used, in more detail than the safety phases). • First aid (Brief first aid instructions are provided for immediate treatment if exposure or contact occurs.) 12/07/2006 Rev B

  28. INTERPRETING SIGNS & WORDS ON LABELS • Emergency procedures (Apply to situations such as spillage, fire or leakage of the substance. This includes type of equipment to be used, Eg. type of fire extinguisher to use). • Details of manufacturer or supplier (The name, address and AUSTRALIAN emergency number of the manufacturer or supplier initially responsible for distributing the substance. This is also the source of Material Safety Data Sheets). 12/07/2006 Rev B

  29. MATERIAL SAFETY DATA SHEETS Reading the Material Safety Data Sheet (MSDS) is the second step in getting more detailed health and safety information on the chemicals used in your workplace. 12/07/2006 Rev B

  30. WHAT IS A MSDS? • A document prepared by the manufacturer of the product, or the supplier. • Available from the manufacturer or through the supplier. • Provides detailed information of a chemical. 12/07/2006 Rev B

  31. MATERIAL SAFETY DATA SHEETS • A MSDS will be available if the chemical is identified as a hazardous substance and/or is a dangerous good. • A MSDS should clearly state if a product is a hazardous substance and/or a dangerous good. • For chemicals which are non-hazardous substances, other types of information may be available which is not set out in the format of an MSDS. • If a MSDS doesn’t tell you what you want to know, then get in touch with the contact person listed on the MSDS. 12/07/2006 Rev B

  32. MATERIAL SAFETY DATA SHEETS • Information on a MSDS aids in the selection of safe products and helps prepare employers and employees to respond effectively to daily exposure situations as well as to emergency situations. • As MSDS are a comprehensive source of information for all types of employers, there may be information that is not useful or important to you. Concentrate on the information that is applicable to your situation. 12/07/2006 Rev B

  33. WHAT DOES A MSDS LOOK LIKE? MSDS formats may be different but should include the following information: • Statement of hazardous nature • Date of issue (not to be more than 5 years old) • Manufacturer’s or supplier’s details (emergency telephone number must be Australian) • Identification section (includes product names; manufacturer’s product code; UN number; DG Class and subsidiary risk; Hazchem code for responding to road emergencies); Poisons schedule number; Packing Group) • Use (recommended or intended use by the manufacturer and methods of application) 12/07/2006 Rev B

  34. WHAT DOES A MSDS LOOK LIKE? • Physical description and properties (covers wide range of technical information on properties such as boiling points, flash points, flammability. Also information on reactivity with other common substances, important when considering safe use and storage) • Ingredients (chemical name, proportions etc. Gives the chemical identity of each hazardous ingredient) • Health hazard information (health effects, first aid, advice to Doctor) • Precautions for use (WorkSafe exposure standards which must not be exceeded; engineering controls for reducing exposure; personal protection (PPE); flammability – to avoid fires and explosions) • Safe handling information (storage & transport; spills & disposal; fire/explosion hazards). 12/07/2006 Rev B

  35. MSDS SUMMARY • An MSDS provides hazards information and information to: • Use • Handle • Store • Transport • Dispose of the material safely and correctly. 12/07/2006 Rev B
