Information on how the aerosol product will be used in normal and reasonably foreseeable use is needed as part of any safety assessment. For example, how and where it will be used, how frequently, how long will it be sprayed and at what spray rate. Certain products present special risks by virtue of their formulations, e.g. oven cleaners and water-proofing sprays. For these Special Products awareness of labelling requirements is necessary.
The aerosol product shall be formulated and designed to reduce the potential for cold burns to the user during application. If, during use, liquid propellant is allowed to come into contact with the skin (or eyes) then a cold burn could occur. This is due to the rapid cooling as the liquefied propellant evaporates. This effect should be considered when choosing a propellant and hardware.
An assessment of safety under conditions of accidental misuse shall be made. An assessment of safety when products are accidentally sprayed into eyes by adults and/or children should also be carried out where relevant. Misuse, resulting in liquid propellant coming in contact with the skin (or eyes), could cause a cold burn to occur. For aerosol oven cleaners containing alkalis or solvents, additional precautions should be taken to minimise the possibility of accidental misuse. Specifically, actuators should clearly indicate the direction of discharge and aerosols should carry adequate warnings. For these products awareness of special labelling requirements is necessary.
