TGHS6: Practical notes: use of gas bags LINKS The use of plastic bags as a means of manipulating gases is a novel technique that has been developed for the videos on this CD-ROM. While offering a convenient means for handling gases, there are potential safety issues: if a bag accidentally comes into contact with a flame or if a bag splits, for example. Note that published model (general) risk assessments do not exist for these techniques.
