These questions categorized as 38 general A substance or mixture with this pictogram has one or more of the following effects: Is carcinogenic Affects fertility and the unborn child Causes mutations Is a respiratory sensitiser, may cause allergy, asthma or breathing difficulties when inhaled Is toxic to specific organs Aspiration hazards, may be fatal or harmful if swallowed or if it Any self-reactive substance or mixture which can detonate or deflagrate rapidly, as packaged; B: Any self-reactive substance or mixture possessing explosive properties and which, as packaged, neither detonates nor deflagrates rapidly, but is liable to undergo a thermal explosion in that package; C a w/w or w/v preparation. Thus a 1:100 ratio strength would mean a solution with 1g in 100ml, or it might mean a solid preparation, say 1g of drug in 100g of ointment. You will use the word “in” to verbally express the relationship between the two numbers. Thus, an epinephrine 1:1000 ratio strength solution would be pronounced epinephrine
