Risk Assessment

Safety signs Risk Assessment What does this safety sign tell you? Trip hazard. What are the trip hazards in a school laboratory? How could they be minimised? Bags and coats on the floor or other things like that would be the most likely. That is why they should be tidied away. Other things like stools out of the way and moving around safely can also be mentioned.

Safety signs Risk Assessment What does this sign tell you? Splashes into the eyes are a serious hazard. Eye protection should be worn. Schools will have different practices on this but tell students what the requirement would be in an industrial setting. Often students will think there is no need to wear safety glasses if they are not doing anything themselves. However, others in the class could still be performing practical work. What should the students be thinking about in that situation?

Safety signs Risk Assessment What does this sign tell you? Corrosive on the skin. Don’t spill things onto your skin, wash off immediately. Could suggest things like wearing gloves if needed although materials used in these activities are not corrosive

What could possibly go wrong? Risk Assessment What are the possible hazards shown by this image. Risk assessment is about assessing the hazards and minimising the dangers. Ultimately it is about deciding whether to do an activity or not. Briefly a risk assessment is spotting and assessing the severity of the dangers (hazards). Then seeing if precautions can be taken to minimise the dangers to an acceptable level. Link in the idea of the chance of something happening as well as the severity of the hazard. Finally the idea that an assessment is made to see if the risk is low enough and that the benefit outweighs the risk.

Your task Risk Assessment Use the risk assessment grid to think about the possible dangers when making and testing a shampoo formulation. Complete the table and suggest the precautions you can take to minimise the dangers Decide if you can work safely Risk Assessment Corrosive on the skin. Don’t spill things onto your skin, wash off immediately. Could suggest things like wearing gloves if needed although materials used in these activities are not corrosive

Discussion Risk Assessment Are there any dangerous materials or processes? What precautions would you take to reduce the risks present? What should be done if something goes wrong? What is the overall assessment? Is it safe to continue? Risk Assessment Corrosive on the skin. Don’t spill things onto your skin, wash off immediately. Could suggest things like wearing gloves if needed although materials used in these activities are not corrosive

Making & Testing a Shampoo

Ingredients and Amounts Formulations Ingredients and Amounts

Formulations Formulations A formulation is a list of ingredients and their quantities - similar to a recipe for a cake! Formulations

Formulations Consistency Accuracy Formulations At Croda we have formulations for lots of different products: Shampoo Conditioner Moisturiser Hair Gel Sun Cream Formulations

Product Development & Testing Making and Testing a Shampoo

Making & Testing a Shampoo NPD – New Product Development Starts off on a small scale Different batches are made to specific formulations Making A Shampoo

Making & Testing a Shampoo Why is it important to start on a small scale in a laboratory? Allows for changes to be made easily – to meet the demands of our customers Different batches can be made to test that each time it’s made it is exactly the same (repeatability) Alert us to any problems we might face when scaling it up to a large size i.e. too thick! Cost effective – you don’t want to waste products by making mistakes at large scales Making A Shampoo

Email Request Making a Shampoo From: Sarah Smith-Shilling To: Croda Team Making a Shampoo

Making & Testing a Shampoo They have started testing this in the lab in a small batch and would like Croda to look at it for them before they scale up to a large batch. Each batch needs to have the same formulation, so accurate measuring and mixing is important. Work in pairs and follow the instructions on the product specification sheet. Making a Shampoo

Discussion Perfume Colour Thickness Shelf-life Discussion How accurate do you think the method is? Is it repeatable? How could it be improved? What other things do you think could be added to the formulation to make it more appealing to customers? Would they like to use the shampoo as it is? Discussion Perfume Colour Thickness Shelf-life

Scale up for Production Why do you think calculating the volume of foam produced would be more accurate than stating the height of the foam? Volume = πr2 x height of foam Extension

Scale up for Plant Production On plant production the quantities are increased Convert your small weights to larger production batch sizes Extension
