These are non-negotiable: - Protective gear - Wear gloves, eye protection, and even a mask if dealing with nicotine concentrates - Ventilation - Nicotine vapours or strong flavourings can irritate so have a window open or a fan nearby - Labels - Put labels on everything, including information about the date of creation, nicotine strengths, ratio of ingredients and the flavour - Safe storage - Concentrated nicotine is a toxin, so store it very carefully and avoid contact with skin - Clean, sterilised tools - Pipettes, beakers, and bottles should all be thoroughly sterilised to avoid contamination - A DIY calculator - Getting your ratios right will avoid overdosing or underdosing, so an e-liquid calculator is your friend - Responsible disposal - Leftover concentrates, used containers, and any other waste should be cleaned up and discarded safely And, most importantly, ALWAYS keep chemicals out of reach of kids and pets
