Alkaline Substances - ST108 Safety Talk

Every year, hundreds of employees suffer severe and sometimes permanent eye, skin and
respiratory damage from exposure to alkalis.

There are, however, many thousands of other employees who have worked with alkalis for years
and never experienced an injury.

We are going to look at how you can avoid being a part of that unfortunate first group

Alkaline Substances - Safety Talk

  1. 1. Alkaline Substances Page 1 of 10 © PA Services Group - SMARTsafe 2013 Document Number: ST108 Revision 2013 1.0 This pack contains: • 7 - Page Talk Text • 7 - 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.

  2. 2. Alkaline Substances Page 4 of 10 © PA Services Group - SMARTsafe 2013 Document Number: ST108 Revision 2013 1.0 ALKALINE SUBSTANCES Accidents involving the use of alkalis usually occur because: we don’t know the health hazards; and we don’t know the safe handling precautions. If a mishap does occur when using an alkali, the outcome can be worse, if: you don’t wear the correct Personal Protective Equipment; you don’t know the required First Aid procedures; and you don’t follow the correct Emergency Procedures. “What is an alkali?” Hand out sheet 1 – What is an alkali An alkali is a corrosive chemical that can very quickly cause tissue damage by burning or dissolving the skin. “What scale indicates how corrosive an alkali is?” The pH of a substance determines if it is an alkali and how corrosive it is. All alkalis contain hydroxide ions, and it is the concentration of these ions that produce the corrosive effects of alkalis. A special measurement scale called pH is used to describe the concentrations. Numbers between 0 and 14 make up the scale, with values greater than 7 representing alkalis and values less than 7 representing acids. A pH of 7 indicates that a substance is neutral – water usually has a pH of 7. Each difference of 1 between two pH values, means that one is ten times more concentrated than the other. For example, detergent can have a pH of around 10. Since the difference between detergent and water is 3, detergents are 10 x 10 x 10 or 1,000 times more alkaline than water. Alkalis such as Caustic Soda has a pH of 14, meaning it is over 10,000 times more corrosive than a common household detergent. This document is a partial preview.

Alkaline Substances Page 7 of 10 © PA Services Group - SMARTsafe 2013 Document Number: ST108 Revision 2013 1.0 A Job Safety Analysis of specific work tasks, such as handling alkalis, serves as the basis for drawing up a Safe Work Procedure. SWP’s provide guidelines for even greater risk control measures to be applied by the operator. FIRST AID TREATMENT The universal First Aid treatment for contact with an alkali is to first rinse the contact area with running water for 15 minutes and then get medical attention. (e.g. eyewash, drench shower). Any contaminated clothing must be removed immediately - there is no time for modesty. Always launder clothing before reusing. With an inhalation exposure you should immediately leave the area and seek medical attention. If you have to help someone suffering from inhalation exposure, don’t become a victim yourself. Use a full-face airline respirator. If poisoning occurs from swallowing, do not induce vomiting – the alkali would have caused damage going down the throat and will do the same coming back up. Dilute the alkali by drinking water and then seek urgent medical attention. REPORT ALL ACCIDENTS OR INCIDENTS INVOLVING ALKALI HANDLING TO YOUR SUPERVISOR SAFE HANDLING Because of the pH difference between an alkali and water, the small amount of water that is first added to the alkali will result in a violent reaction (e.g. splattering and fuming). By adding the alkali to water, the greater volume of water prevents such a violent reaction. Remember, if you want to dilute an alkali spill with water you must: wear the required PPE; clear everyone else from the area; stay upwind and well away from the spillage; use plenty of water and allow it to run into the spill; and never put the water directly onto the spill. To do so would produce a violent reaction and produce dangerous vapours. “What is the best way to minimise the effects of an alkali exposure?” Hand out sheet 5 – First Aid treatment “Why do we never add water to alkali – always the alkali to the water?” This document is a partial preview.
