Remember to only use industry approved barrel blocking devices. The preffered device is a barrel sock/cover/condomn. A barrel plug is still acceptable at many fields. However a barrel sock is the best option. A swab or squeegee is not an acceptable substitute. Neither is placing the marker in your pocket, holding your hand over the barrel, or removing the barrel. Your eyes are way too important to use anything other than an industry approved BBD.
For a good example as to what could happen if proper safety measures are not taken I reffer you to 1-I's medical folder.
