I mixed my sensitiser from stock solutions and used it immediately without
any harm.
A red safelight is desirable. My solution proved too sensitive any other
way. It was easy to coat under the red (ortho) safelight as it pale
yellow-green which showed up well; much better than under a yellow
safelight.
