Unlike other types of hazards, airborne contaminants are often invisible because of their size or nature.
You may not be able to see, feel or even smell them. An airborne contaminant is any type of material or
gas that does not normally occur in the atmosphere.

Preventing airborne contaminants from entering the workplace and providing adequate ventilation are
the first steps that should be taken. Sometimes this is not possible and respiratory protective equipment
must be worn.

  • 1. Air Purifying Respirators Page 1 of 11 © PA Services Group - SMARTsafe 2013 Document Number: ST049 Revision 2013 1.0 This pack contains: • 8 - Page Talk Text • 8 - OHP Presentation Slide Pack Using the talks (Extract “How to Present Safety Talks”): Plan which topic you want to discuss with your team. Read through the script before you hold the meeting to familiarise yourself with the material. Start the talk with a comment that makes the topic relevant to the team. For example, if you have seen a number of people using ladders incorrectly, use this as your opening comment. Follow the script but don’t read straight from the page. The script is only a prompt and it will sound better if you use your own words. Ask the questions as they appear in the script. It is important you do this because they are a lead in to the next section of your talk. Give the team enough time to answer the questions. Safety talks can be boring for the team if you are the only one talking. Hand out the information sheets as they appear in the script. Don’t hand out all the information sheets at the start of the talk otherwise there is a temptation for the team to read ahead and not listen to the points you are making. Collect the information sheets at the end of the talk so they can be used again.

Air Purifying Respirators Page 4 of 11 © PA Services Group - SMARTsafe 2013 Document Number: ST049 Revision 2013 1.0 AIRBORNE CONTAMINANTS “What are some of the airborne contaminants that you can find in the workplace?” Hand out sheet 1 – Airborne contaminants The kinds of respiratory hazards which may require the use of respiratory protection includes: particulate contaminants; gas contaminants; and oxygen deficient atmospheres. Particulate contaminants are tiny solid or liquid particles suspended in the air. Fumes are solid condensation particles of extremely small size. Fumes are found in the air where soldering, welding and brazing work is carried out. Mist is tiny liquid droplets given off whenever a liquid is sprayed, mixed or agitated. Spray painting is an example of where mists are formed. Vapours are formed by the evaporation of liquids. Solvents that are used in spray painting, such as acetone, generate vapours. Toxic gases are any gases that are capable of producing injury when entering the body in sufficient concentration. Examples include chlorine, ammonia, sulphur dioxide and hydrogen cyanide. Dust is solid particles suspended in the air which are created by cutting, grinding, crushing and handling of solid materials. Silica dust generated by the cutting of bricks is an example of dust that is particularly harmful to the lungs. Gas contaminants are toxic gases and vapours that are present in the air. Oxygen deficiency is a respiratory hazard. An atmosphere with an oxygen content below 19.5% of the atmosphere is harmful to the human body and is termed “oxygen deficient”. This usually occurs in poorly ventilated areas such as confined spaces. e.g. workshop pit. This document is a partial preview.

  • 3. Air Purifying Respirators Page 7 of 11 © PA Services Group - SMARTsafe 2013 Document Number: ST049 Revision 2013 1.0 To provide adequate protection the mask must be worn at all times while exposed to the contaminant. If you have to remove or adjust the mask, leave the contaminated atmosphere. HALF-FACE RESPIRATOR MASKS Hand out sheet 5 – Half-face respirator masks Half-face respirator masks are similar to disposable mask respirators but have a more complex design and a higher filtering efficiency. Half face respirators consist of a rubber or flexible plastic mask which is designed to cover the nose and mouth area. Replaceable filter cartridges are screwed into the mask in front of the inhalation valves. Half-face respirator masks can be used for protection against particulate contaminants and certain types of gases. They are fitted with inhalation and exhalation valves. Half-face respirator masks reduce the level of particulate and gases by passing the contaminated air through an absorbent material contained inside the cartridge. The absorbent can be charcoal or some other special material. Hand out sheet 6 – Filter cartridges The three types of particulate filter cartridge are: Class P1 used for filtering dusts; Class P2 used for filtering out dusts such as silica and asbestos metal fumes from welding; and Class P3 used for protection against highly toxic or highly irritant particulate such as beryllium dust asbestos and metal fumes from welding. A gas filter cartridge may be very effective in filtering one type of gas but totally ineffective in filtering out another type of gas, so it is important that you know how to select the correct type of cartridge. Gas filter cartridges are made from different colour plastic material and labelled with: the type of gas they are designed for; and their absorption capacity. The gas type is indicated by a standard letter and in some cases, the name of the gases they are suitable for. For example, a type K filter is designed for filtering ammonia The absorption capacity is indicated by a class letter or number. The higher the number the greater the capacity of the filter.

  • 4. Air Purifying Respirators Page 10 of 11 © PA Services Group - SMARTsafe 2013 Document Number: ST049 Revision 2013 1.0 SELECTING THE CORRECT RESPIRATORY PROTECTION Selecting the correct respiratory protection requires knowing what type of contaminant is present and in what concentrations, particularly with toxic gases, vapours and dusts. If you are unsure, check with your Supervisor or Safety Adviser who will arrange for atmospheric sampling. If you know what contaminant is present but are unsure of what type of respirator and filter cartridge to use, refer to the Safety Data Sheet which will tell you the correct type of respiratory protection to wear. Failing this, refer to your Supervisor or Safety Adviser. SUMMARY Air purifying respirator masks cannot be used as protection in atmospheres that are deficient in oxygen. Make sure that you wear the correct respiratory protective equipment for the type of airborne contaminant that is present. Always check the respirator seal, because without the seal you are not protected. Wear your respirator at all times where a contaminant is present. Change disposable respirator masks, filter cartridges and canisters as soon as you suspect they are becoming clogged or failing to filter out the contaminant. If there is any doubt as to what respirator you should be using, refer to Material Safety Data Sheets, your Supervisor or Safety Adviser. FURTHER REFERENCES FOR THE SUPERVISOR/PRESENTER ISO and/or Country Standards relevant to your country or region some examples: United States NIOSH European standard EN 143 European standard EN 149 AS/NZS 1715 - “Selection, maintenance and use of respiratory protective devices.” AS/NZS 1716 - “Respiratory Protective Devices.” Other References: http://www.ccohs.ca/oshanswers/prevention/ppe/respslct.html This document is a partial preview.

  • 6. Air Purifying Respirators – ST049 © PA Services Group - SMARTsafe 2013 Class P1 masks are used for filtering dusts such as silica and asbestos. Class P2 masks are used for filtering metal fumes They cannot be used as protection against: • highly toxic dusts; • Toxic gases; or • Vapours. Check the mask for: • holes in the filter material; • Strap tension; and • Secure metal nose clip. Check the face seal before using the mask.
